Ask HN: What's your quarantine side project? - <AUTHOR> For those who are still under lockdown, what are you working on / building / learning?
I've been making excessive amounts of bread. <comment><USER8> All: apologies for the interruption, but don't miss that there are multiple pages in this thread, with over 2000 posts by now. You have to click through the More links at the bottom to see them all. Later pages have all kinds of stuff that is just as interesting. It's kind of incredible.

(We intend to get rid of pagination once the next implementation of Arc is ready.)

<comment><USER8> Replies to this top comment have been quite a job to juggle. My approach has been to reply and then detach them, so as to minimize distraction at the top of the thread. Unfortunately, that has led to the same questions being asked over and over, so I'm going to move all the replies underneath this stub, and then collapse it. The reason for a stub root comment rather than just collapsing all the replies is that a list of dozens of collapsed replies would take up most of the page.

I'm also going to partition them by topic, since there are so many.

<comment><USER8> If you want to reply about Arc, do so here.

<comment><USER9> I'm trying to write this in a way that does not come across as sarcastic or ungracious, but does it strike anyone else as odd that this change blocks on the next version of the underlying programming language?

<comment><USER10> Given that both the language and the forum are developed in tandem, and are linked to the degree that they ship together, it wouldn't be surprising that changes in Arc would be made specifically with the forum in mind.

[https://medium.com/endless-filament/make-your-filament-at- ho...](https://medium.com/endless-filament/make-your-filament-at-home-for- cheap-6c908bb09922)

Hopefully, this will reduce the use of virgin plastic for creating art pieces in 3d printing community and you might be able to create beautiful and useful things out of waste plastic while cleaning plastic waste from the environment.

It's a profitable business.

I worked on this in my free time during quarantine.

I want to make the project more accessible so people around the world can develop local recycling unit. There is lots of work which needs to be done including making parts more standardized, demonstrating how parts fight together in a visual way and also have a microcontroller firmware to control diameter of filament. I don't have much experience with microcontrollers but I've ideas, so we'll see.

<comment><USER12> Some guys in our city are doing this on a larger scale, schools in the area collect all plastic bottles and in return they get 3d filament: [https://www.greenbatch.com/](https://www.greenbatch.com/)

<comment><USER11> Wow that's great, I wonder how they modify the PET polymer, as I've been researching it's not an easy polymer to print with atleast not without the glycol modification which is usually sold as PETG.

Any idea how they are doing it?

Naturally, this got very boring very quickly, so I made a Chrome extension which upon a click connects to a Voximplant app which calls the concierge, receives his voice input, forwards it to Dialogflow, and uses the intent recognized by DF to play back recorded audio tracks of my voice asking for a pass, answering questions or thanking the concierge.

I'm thinking about making the extension intercept the traffic to the website of my favorite delivery services and automatically place the call so the button click also won't be required.

<comment><USER14> This is my view of the AI dystopia. AI for calling concierge, AI for answering concierge, AI for monitoring the concierge calls, AI for all the pointless things that humans used to do, but expanded and accelerated massively. Humans spending their lives training AI to defeat some new attack or spam bot.

<comment><USER13> The "AI" part here is a bug, not a feature. I wouldn't have to do it if I had an API for sending requests, or a condo-provided app, or at least if the concierge service used e.g. Telegram officially. Since neither of these is true, I had to resort to a workaround.

We designed it in Sketchup, did a material takeoff in Excel, and built it with lumber that got delivered to our house. 4' high, 8' wide and 29' long—-and hours and hours of fun. Teaching things like trig and how to use a chop saw and the difference between different grades of plywood to a boy who's learning-starved since school closed has been one of the more rewarding things I've ever done.

<comment><USER16> Excellent project. Not as hard as a half pipe, when I was 8 my Dad and I built a lumber bike rack. Classic memory, its still stationed in front of the garage having taken quiet a beating. During the summer every night of mine and my siblings - sometimes drunken - teenage buffoonery for years on end ended with us riding/crashing into each slot.

</comment></comment><comment><USER17> I created [https://web.trango.io](https://web.trango.io) a LAN based calling and file sharing service. Essentially, you can share files, make video and audio calls to those on the same network as you without having to go through the internet. Your data never leaves your local Wifi. The internet is only used to discover those on the same network as you. We use webrtc and a signalling server to make this system work.

We were in the same office and needed a fast, simple way to communicate with eachother without coming in close contact (covid 19) and wanted to do that over LAN rather than use tools over the internet NOR use our ancient intercom system. So now we are using this internally for fast file sharing and good quality video calls.

Going to be introducing group calls soon and also the ability to integrate online calling and file sharing.

<comment><USER18> This is a really great idea from the security and privacy point for small teams and offices. And for sharing stuff in a house! Would this work through a VPN?

you could also introduce differnt channels, so different groups of ppl can chat . And you should add text chat through the data channel

<comment><USER17> Thank you!

It works over some VPN's but not all. We will look into why and try to resolve.

Yes, it works very well when we need to call eachother or share files with eachother in the office. At home, I mainly use it to share large pictures and videos with my wife as it is very fast.

Yes, different channels and group calling should be added. We could add a chat function in it aswell.

Even though it is based on your local wifi and the data never leaves your home/office network, we have still encrypted it by default so we can integrate online calling and file sharing in a secure manner and dont have to redo the whole security aspect again!

[https://github.com/doersino/aerialbot](https://github.com/doersino/aerialbot)

I've built this tool because satellite imagery can be extremely beautiful [2], and I was looking for a way of regularly receiving high-resolution satellite views of arbitrary locations such as the center pivot irrigation farms of the American heartland [3] in my timeline. Plus, for obvious reasons, it's nice to see the world without actually having to go outside right now.

Currently, I'm running two Twitter bots based on ærialbot:

* @americasquared, which posts one randomly selected square mile of the United States every 4 hours: [https://twitter.com/americasquared](https://twitter.com/americasquared)

* @placesfromorbit, which analogously posts a 5×5 km square anywhere in the world every 6 hours: [https://twitter.com/placesfromorbit](https://twitter.com/placesfromorbit)

I finally put my photos up on my personal website. The only constraint I gave myself was to build a site that doesn't need Javascript to load.

In the end I ended up using Next.js as a static site generator that pulls all the routes from my directory structure, making it possible to add new photography collections and filters as I go.

Might be overkill for the use case but it was fun to learn. The irony is I had to write a bunch of JS to produce it.

Still need to optimize the image sizes and I am thinking about adding filters for b&w/color/format.

<comment><USER23> Pretty cool!

OP, have you tried loading="lazy" ? I don't know if it works with the picture tag but it is worth trying I think.

Very often, webpages contain many images that contribute to data-usage and how fast a page can load. Most of those images are off-screen (non-critical), requiring user interaction (an example being scroll) in order to view them.

Loading attribute The loading attribute on an  element (or the loading attribute on an ) can be used to instruct the browser to defer loading of images/iframes that are off-screen until the user scrolls near them.

I was curious about the picture tag. Here is what Mozilla documentation says [https://developer.mozilla.org/en- US/docs/Web/HTML/Element/pi...](https://developer.mozilla.org/en- US/docs/Web/HTML/Element/picture) :

The HTML <picture> element contains zero or more <source> elements and one  element to offer alternative versions of an image for different display/device scenarios.

The browser will consider each child <source> element and choose the best match among them. If no matches are found—or the browser doesn't support the <picture> element—the URL of the  element's src attribute is selected. The selected image is then presented in the space occupied by the  element.

To decide which URL to load, the user agent examines each <source>'s srcset, media, and type attributes to select a compatible image that best matches the current layout and capabilities of the display device.

The  element serves two purposes:

It describes the size and other attributes of the image and its presentation.

It provides a fallback in case none of the offered <source> elements are able to provide a usable image.

Common use cases for <picture>:

Art direction. Cropping or modifying images for different media conditions (for example, loading a simpler version of an image which has too many details, on smaller displays).

Offering alternative image formats, for cases where certain formats are not supported.

Saving bandwidth and speeding page load times by loading the most appropriate image for the viewer's display.

If providing higher-density versions of an image for high-DPI (Retina) display, use srcset on the  element instead. This lets browsers opt for lower-density versions in data-saving modes, and you don't have to write explicit media conditions.

<comment><USER22> Good point I hadn't thought of that. Still have to troubleshoot it a bit in Firefox but it looks like its working in Chrome.

The resolution scaling is a good idea as well. I used the picture tag initially as a fallback for browsers that don't support webp images. More importantly I need to actually create scaled images which I have been putting off...

Thanks for your comments/advice!

[https://seanwilson.itch.io/wordoid](https://seanwilson.itch.io/wordoid)

I've tried to make it intuitive enough that you don't have to read a page of instructions first but let me know if I've missed the mark. I'm hoping you can learn the gameplay mechanics as you play.

I'm not using any web frameworks for this which was actually fun to do. It gave me a chance to improve my understanding of CSS animations + reflows, and catch up with changes to JavaScript.

<comment><USER26> Just played with it for a few minutes, I liked it! The only bit that occasionally tripped me up was going diagonally in my word construction, but I got the hang of it after a few rounds.

One thing that may make this easier is beveling the edges of the tiles slightly so you don't accidentally select letters on either side of the diagonal unintentionally.

<comment><USER25> Great, thanks for the feedback!

> One thing that may make this easier is beveling the edges of the tiles > slightly so you don't accidentally select letters on either side of the > diagonal unintentionally.

Thanks, I'll have a play with that. If you use your web devtools to inspect the HTML, you should see over each letter tile, there's actually an invisible tile on top of each one at a 45 degree angle that's being used as the real touch/mouse target for selecting letters (as accidental selection is awful if you use the actual tile as the target). Maybe there's a more reliable way but playing with the target shapes and sizes will probably help.

1) Trail Router ([https://trailrouter.com](https://trailrouter.com)) - This is a running route planner that favours greenery and nature in the routes it generates. It can generate point-to-point or round-trip routes that meet a specified distance. I developed this because I am (or was...) a frequent traveller for work, and want to run in nice areas rather than by horrible busy roads when I'm visiting somewhere new. Naturally, the utility of this tool is limited at the moment for people stuck in lockdown!

2) Fresh Brews ([https://twitter.com/FreshBrews_UK](https://twitter.com/FreshBrews_UK)) - I've been touring the UK's finest craft beer breweries from my own home in recent weeks. New beer releases sell out very quickly and I was frequently missing out. Fresh Brews is a simple bot that monitors the online shops of my favourite breweries and posts when a new beer is released to the shop, or an item comes back into stock.

<comment><USER28> Super nice work on trailrouter. The several routes it produced for me in Berlin look quite nice, being familiar with the surroundings.

Would be cool to see how you built it, if you put it on github.

I'm curios about building a similar thing for cycling – crazily neither Komoot nor Google Maps let you filter by type of road, and I'd like to select _only_ bicycle paths and roads where cars can't go. Even if it means cycling much longer, I'd simply like to avoid cars and in Berlin it's possible 90% of the time.

<comment><USER27> I wrote a long reply to someone on the Graphhopper forum who was trying to do similar to you. This may be helpful: [https://discuss.graphhopper.com/t/can- someone-make-a-video-t...](https://discuss.graphhopper.com/t/can-someone-make- a-video-tutorial-of-how-to-create-customize-a-routing-profile-or-walk-through- the-process-in-much-greater-written-detail/5189)

I'll probably write a blog post on how it's built though - there's quite a lot going on under the hood!

Supporting cycling is a possibility for the future. I don't think you'd want to absolutely exclude non-cycleways (as it might make many routes impossible), but you could certainly weight very heavily against them and show on the map which parts of the route were dedicated to cyclists vs which were not.

<comment><USER29> Congratulations on creating trailrouter! This is one of the most unique and useful side projects I've seen in quite a while. I had a lot of fun looking at the various suggestions it offered for my neighbourhood, and I could see how this could help people enjoy their neighborhood a lot more.

If you have the time, I'd also love to read a blog post (or even series) explaining how you built this. Your answer on the Graphhopper forum was very clear and makes me think that a more detailed version could be super useful for a lot of people.

Nice work!

<comment><USER27> Thanks very much for the kind words! I wasn't sure if others would find the technical details of this topic interesting (it's my first foray into GIS work), but it sounds like they would, so consider a blog post in the works.

It is an electron (toolbar) app, which uses WebRTC, so should be fully P2P.

It is too early to use or show, but I did not want to miss out on this thread!

[https://github.com/pompals/pompals](https://github.com/pompals/pompals)

<comment><USER31> I don't know much about WebRTC or electron, so forgive me if this question makes no sense: if it's a simple toolbar app (such as a Chrome extension) why is electron needed?

<comment><USER30> Hi! When I say toolbar, I mean in the native toolbar (runs outside the browser) - we decided with this approach due to the fact you may not always be in a browser (coding for example).

</comment></comment></comment><comment><USER32> Well, my main side project is the same as it's been for the last couple of years, an animation/vector editing tool written in Rust: [https://github.com/logicalshift/flowbetween](https://github.com/logicalshift/flowbetween)

It's sort of starting to make the transition between a pile of ideas and an actually useful tool at the moment. The whole idea is to be a vector editing application that works more like a bitmap tool when it comes to painting, so there's a flood-fill tool and a way to build up paths just by drawing on the canvas rather than having to manually mess around with control points.

The way I built the UI is unique too I think. Choices for UI librarys for Rust were quite limited when I started so I built it to be easy to move to different libraries. I don't think there's any other UI library in existence that is as seamless for switching between platforms (or which can turn from a native app to a web app with a compiler flag without resorting to something like Electron)

<comment><USER33> I suspect that [https://github.com/hecrj/iced](https://github.com/hecrj/iced) would now be another UI library that's as seamless for switching between platforms. Flutter might qualify too (or might not).

<comment><USER32> I've been keeping an eye on the various UI libraries when they come up: right now it seems to take me around a month to add a new one so I'm waiting for one to get traction.

Something else that's a problem is that as a drawing app, FlowBetween wants to be able to get access to data from a digitizer: pen pressure and tilt in particular. A lot of UI libraries don't think to pass that through from the operating system, or have an awkward API (browser support is also very spotty for this)

<comment><USER33> Yeah, lack of support for different input media has been a real pain point for me—most of the developers of these things have mice only, and don't stop to bother about touch or pen input. I use a Surface Book which has mouse, touch and pen, and I like to _use_ all three forms at various times.

If you're trying to do touch and pen on non-web platforms, things tend to be very messy if you want to handle all three types of pointers optimally.

But browser support spotty? I find the pointers events API a _marvellous_ abstraction over platform differences, doing the right thing automatically for >99% of cases, and making the remaining cases possible. The only thing I feel it actually _lacks_ is standardised gesture support for touch. I wrote a simple pressure-capable drawing app a couple of years back in the very early days of pressure-sensitivity (back when Edge was the only browser on Windows that supported it, so I targeted Edge only until other browsers got it), and I found it a refreshingly straightforward system to work with. And since then, everyone implements things like tilt and pressure.

So I'm curious to hear what you're quibbling over, as someone that's been using this stuff in anger more recently than I.

<comment><USER32> I suspect some of my experience is now out of date, as it's now spread out over quite some time. The most recent issue I had to deal with was Chrome: when drawing the canvas at high-res it was being a bit slow at blitting some bitmaps and so was running at 30fps. Something is tied to the framerate with the pointer events implementation and so the events also lagged behind, which made drawing on the canvas quite difficult as the display was 250-500ms behind the user. Eventually 'fixed' by turning the resolution down, but it was a real pain finding what part of the application had got behind (FlowBetween being designed not to lag but to catch up when the display can't keep up). That's quite a subtle one and the pointer events lagging is easily mistaken for the frame rate lagging.

Other browsers don't do this, but they've had a few other issues: what I remember in particular - some only support pressure information using the touch API, and some seemed to support pressure information on different APIs on different platforms, so both pointer events and touch events were needed.

All of these are maturity issues rather than real problems with the API, though and I haven't re-checked some of the older issues recently - <USER2> Chrome issue was still happening back in January so might still be around, but the others I last encountered over a year ago so may have been fixed by now.

<comment><USER33> If you haven't been using it, make sure to use PointerEvent.getCoalescedEvents where available, which unlinks the events from the display frame rate. Anything using pointer events for drawing should use it. (But remember that events can come in at any speed, e.g. a 240fps pen should coalesce four events per 60fps frame—so make sure you can cope with lots of events.)

I _believe_ that the pointer events API is in current browsers now uniformly superior in functionality to the touch events API which it obsoletes.

</comment></comment></comment></comment></comment></comment><comment><USER34> I've spent a decent amount of time learning over the time that this quarantine has been going on.

A major issue that I've seen is that of most beginner-focused educational content not being fast enough to learn with for the more experienced developer. This along with the fact that time is often a big issue for us. I've had numerous times where I had to learn a new framework within a 1-2 week time span in order to plug some work gap or speed up a project, and found no legitimate resources that could allow an intermediate developer like me to learn faster.

This is why I am currently creating content targeted specifically at intermediate to advanced developers and teaching new languages and frameworks (using the 'constructivist' method) in a way that makes the process of learning them much more efficient. In short, faster.

It's a little rough around the edges but you can check out the blog where I share my current tutorials here: [https://fromtoschool.com](https://fromtoschool.com).

To gain a better understanding of why the method of teaching that I've described is more efficient than others for the intermediate developer, check out this post: [https://fromtoschool.com/why-most-programming-tutorials- are-...](https://fromtoschool.com/why-most-programming-tutorials-are-so-hard- to-understand-and-a-solution-to-this-problem/).

Frustrated by filter bubbles and the general state of online debate, especially on Twitter, I made Debubble.

It's a publishing tool that will let you challenge another Twitter user to a debate. If they accept, the two of you will be able to engage in a public but distraction-free conversation. Debubble will make sure you wait for your turn before you can deliver your arguments. It will also limit each response to 1500 characters (roughly one page) and the entire debate to 12 turns. Instead of cheering for their side like sports fans, registered readers will be able to signal the value they got from your conversation by starring the whole debate.

I haven't properly tried to launch it yet, as my day job and kids are keeping me very busy at the moment.

<comment><USER37> I really like your 'starring whole debate' mechanism, that seems like huge innovation.

The trend is to just reuse the standard up/down voting comments without realizing implications. Yes, if you do this and sort comments by votes you will on average get higher quality user-curated content. OTOH small piece of UI is using reward system to condition users to seek attention, and it sets the tone for whole discussion.

There are no easy solutions here. Everyone wants their opinion to be heard (even if somebody already expressed same thing). That will sometimes mean aligning your opinion to masses so that your content gets proper visibility, which leads to echo chambers and bubbles. Your take forces users to bring attention to all of debate and not just to one side's arguments. Clever.

<comment><USER36> Thank you for the positive feedback. That's pretty much where I'm coming from: "likes" have created an unhealthy dynamic in online conversations and I was wondering if there could be a hack around that.

</comment></comment></comment></comment><comment><USER39> I've been working on converting a Mazda RX-8 to electric. At the moment, that mostly amounts to making battery boxes to go in the various empty spaces by tig welding aluminum (which I had no experience with prior to this project).

The general plan is to use about 400 pounds of lithium iron phosphate cells, spread between the spaces under the right and left rear passenger seats where the gas tank used to be and the engine compartment (mostly approximately where the radiator was). I'm using a Netgain Hyper9 AC motor (144 volt version). I haven't decided what I'll do for charging and battery management. I plan to order an adapter from CanEV to interface to the transmission so I'll be able to keep the stickshift.

<comment><USER40> Whoa! That sounds like an incredibly fun project. I am not questioning your plan, as you are almost certainly more knowledgable than myself, but is there any technical reason to actually keep the manual transmission? I thought one of the biggest advantages of electric drive vehicles was a relatively linear power/torque curve.

<comment><USER41> Most EV conversions end up keeping the manual gear box because it's simply easier to build an adapter plate for the motor transmission interface than it is to build out a whole new gearbox replacement.

From what I've seen it's fine, you can choose which gear to shift to and leave it there. Cold start from 5th gear. Can even be fun to play with the gear ratios, apparently. But it is another point of failure.

One of the things holding me off from attempting an EV conversion on my old Saab 900 sitting in my shop is that the gear box in it is notoriously brittle and would break even with the torque from the (turbo) gas engine that it shipped with.

<comment><USER42> The real problem with that is weight. Because SAAB is -- well -- SAAB. Great company, great car btw.

This time around the tech stack is React js as the UI with Springboot and MongoDB in the backend. Making great progress can do lists/task crud but lacking sync etc..

When you are accustomed to how things work and then forced to change its not fun. Current covid19 circumstances brought enough unwanted changes. This project started out as a fuck you to MS but it really turned into a fun project to keep my productively on track and also keep my mind busy.

The only shame is that I can't really "release" this cause it really looks like the original and the copyright vultures will waste no time coming for me. My best bet would be to change the UI design. BUT that would void the original purpose of the project.

We're working with other local maker-y spaces on these efforts; we've picked up a few Ender 3's to help with the 3D printing and we have a small team of volunteers helping with sewing. So far we've distributed over 1,500 face masks to folks and healthcare workers in Fresno, San Diego, Idaho, and soon to a school in Uganda.

This is all on top of trying to keep our community engaged and hosting meetups and happy hours on Zoom. Also on top of my day job. I've never been so busy in my life, and I'm looking forward to a time when we can safely re-open and get back to building the community face-to-face.

Especially after having seen and almost daily used dplyr with R, when having to use something else, I miss that convenience of a clear and consistent API and the chaining of operations. I don't know yet if this project makes sense in terms of speed and corner case handling. I haven't done any real-world work with it yet, but at least it's been a good learning project.

<comment><USER52> As someone who uses pandas daily and detests it violently, godspeed.

<comment><USER53> One interesting usecase for a Pandas replacement is AWS lambda functions. If you have a skinnier package that can get 80% of the data-processing niceness whilst using up a smaller % the Lambda function's size limit this could come in very handy for many people.

Also agree that the dplyr syntax is cleaner.

I'm a keen mountain biker, so I've put my energy and frustration into developing new mountain bike trails in the hills around my house. Been meaning to do this for a long time, but there are such good trails a few miles further away, so the incentive has not been very strong until now.

I'm building for about 1 hour per day on average, and I manage to get between 10 and 100m of trail built in that hour, so by the time the lock-down ends I'm aiming to have a contiguous piece of singletrack that's a mile long.

Also, I've been helping on a local project to develop an open-source ventilator ([https://www.backabuddy.co.za/champion/project/rescuevent](https://www.backabuddy.co.za/champion/project/rescuevent))

And I'm working on a peer-to-peer donation platform (which is not really ready to show to anyone yet)

<comment><USER55> Creating a new trail sounds interesting - I had to do similar as part of a service project when I was a kid, but I imagine it's much more fulfilling when it's for your personal use. How are you able to create the trail, is it free use public land, or more of a guerrilla repurposing of untended private land?

<comment><USER54> The land is in limbo: it's abandoned pine plantations currently being used by joggers, dogwalkers and (to a lesser degree) cyclists.

I can highly recommend trail building (both walking and cycling trails) as a combination of physical, aesthetic and intellectual challenges (figuring out how to use the terrain to be both fun and interesting/possible to ride and then moving tons of earth and vegetation to make it happen).

I've been a musician for going on 20 years, mainly piano but I like to collect the ability to noodle on instruments. When I was around 13 I broke my left forearm and it healed in a way that limits the rotation of my wrist quite a bit. This makes playing guitar rather difficult and at the time I started to consider branching out from piano there were a bunch of factors that made me give up on being able to play guitar. I was gigging as a piano player for 10-12 hours a week, while also going to school for piano and CS I started to develop tendonitis and trying to play guitar made it a lot worse, so I quit. I'm now in a place where I can take care of my arm (and I have actual healthcare) so I started back up again.

I guess HN is cool with self-promotion, so here's a jam I made with a looper pedal after about 2 weeks. I call it "More Theory Than Experience"

[https://youtu.be/_beFK_j-Dk8](https://youtu.be/_beFK_j-Dk8)

<comment><USER58> How did you learn? :) Any resources you can recommend? I used to learn but dropped it as couldnt find good resource to learn on my own

<comment><USER57> I took a rather circuitous route of playing and learning piano for 15 or so years (I'm 25 btw, I just started early) and being a massive theory nerd. I also taught myself piano until I got to college, which I think gave me unique perspective but I also know took waaay longer than it I'd just taken lessons. At the same time, I really enjoyed learning as a passion instead of a commitment. There were times I walked away but I always came back. That's just me though; if you learn better with the mild pressure of a teacher's tutting that's absolutely valid.

I've currently teaching myself as I just love exploring. I've watched some youtube videos about scales and I follow a few guitarists on youtube (samurai guitarist[0] comes to mind and Paul Davids[1] has probably been my biggest influence in my ability to play). Other than that, it's all been throwing all of my experience at it and seeing what sticks and what doesn't. Definitely record yourself once and a while to see what's working, and listen to a lot, both passively and actively, and try to spot what you like and really analyze it.

speaking of which, I've found music theory to be completely indispensable in my ability to self-study. Being able to take what I heard and internalize it, and being able to take what's in my head into my hands is absolutely essential.

<comment><USER58> That's awesome!

You sorta motivated me to pick up guitar again... the sound of it makes me excited so gonna cont. with a course I bought on Udemy and see how far that takes me.

I'd also checkout Samurai guitarist and Paul Davids.

[http://pointillism.digitalbunker.dev/](http://pointillism.digitalbunker.dev/): I've always been into generative art, so I built this site that takes a source image and recreates it in a Pointillism style

[http://gitrandom.digitalbunker.dev/](http://gitrandom.digitalbunker.dev/) : Generally when I'm struggling to come up with project ideas, I'll just browse GitHub. This site lets you explore random GitHub projects by language and topic.

I built the sites using Vapor, so I could continue to use Swift and just learn one new thing at a time.

I'm probably going to pick up some iOS app too to leverage the new hobbies people are discovering being at home (i.e. bread making).

Real-time avatars with our deep computer vision pipeline; developed with GStreamer, Rust and LibTorch. This CV pipeline is usually used for training robots inside simulations and generating synthetic datasets. But given the circumstances, thought it would be fun to explore other use cases.

<comment><USER63> Cool work. I went bankrupt trying to turn similar tech into an advertising platform 15 years ago. Long before the term 'deep fakes' I had a fully functional photo to 3D avatar reconstruction pipeline and VFX production pipeline for realistic actor replacement in media. I went as far as acquiring global patents. But I was too early - no one believed what I was doing was possible in '08 (when I was pitching my working system to VCs). By '13 I was exhausted, broke and dismayed at the short sighted and entitled attitudes I'd encountered. I gave up and now work in facial recognition.

I was looking for a Zettelkasten note taking app which would 1. work on laptop and phone 2. wouldn't have any vendor lock-in and 3. wouldn't go away if a single company folded - couldn't find one, so I started writing one. I'm writing it as a PWA to make it available ~everywhere and planning to use dropbox/google drive/whichever as the backend so users will have full control over their notes.

I'm amazed how much you can accomplish with modern web tech stack. I can literally bypass any need for a server by having the user connect to their cloud! I can just create a PWA and publish it as an app! On the downside I've learned that some features are hard to implement with above requirements using PWAs though. For example, only Chrome supports some level of filesystem access, so storing notes locally would mean discriminating by browser, which I don't feel great about.

[https://feather.id](https://feather.id)

It's a RESTful server-side API for adding user authentication and authorization flows to your apps.

We've been taking a lot of inspiration from Stripe and mostly just wanted to use an auth service with docs like Stripe :)

(Please note this is still pre-pre-pre beta. The docs are incomplete and we have yet to even integrate it with our own apps, so please don't try to build an app with it yet!)

<comment><USER66> I applaud this and wish you luck. I'm a big cheerleader of Auth0 and have used them in the enterprise setting and in side projects. They do a lot of things right and have such promise for becoming the "why would you choose anything else" solution. They have all the mindshare of JWTs by owning jwt.io. But I must say that the documentation is truly awful, and I think that leaves them vulnerable for a competitor.

The core API docs are good, like the Management API Tester page. But the walkthroughs and general documents are full of broken links, inconsistent use of language, and varying levels of precision in how things are explained. You end up Googling for answers, finding community responses, and having to piece things together.

The way things are called APIs versus Applications is confusing no matter how you put it. Then they are sort of ambivalent in places. For example, look at the SPA guides. Sure, it'll walk you through the Implicit Flow for SPAs, but elsewhere they second guess themselves and say you shouldn't use Implicit Flow for SPAs. Instead, they say create a "Normal Web App". But good luck finding that specific article again just because you came across it once!

If anyone in Product or Biz Dev at Auth0 is reading this, I would urge you to make a case for "even easier mode" that abstracts a bit more and comes with better documentation. I found myself doing so much token management and head scratching about ID versus access tokens that I felt like I need to be a technical expert on the standards just to follow the directions and feel like my app is secure.

Auth0 has potential to actually solve identity in an easy way, but they are not meeting that promise right now, and that is your opportunity.

<comment> nick-garfield Thanks for this comment!

We had the same exact experience. Couldn't have explained the state of the docs any better!

[https://gardunha.net](https://gardunha.net)

It's a nice mix of both online and offline work. Also, the community around here is mostly made up of various combinations of farmers, hippies, retirees, and permaculture folks. Everyone wants a decent internet connection, but no one really has the skills to do much about it. I've lived here a year now, so thought I'd give it a go.

It's a windy road. Actually, it all started out because I wanted to get fast internet for myself on my farm. Then I thought, "Hey, why not start a business?" Feature creep at its best.

<comment><USER68> This is amazing, I've been thinking of doing the same for my area. I've always wondered about the ping tho. Right now I have 4ms with my current provider which uses a wired connection. Whats the usual ping using radio? (from a client perspective)

<comment><USER67> The radio will generally add 2-3ms latency I believe. Plus any routing latency at the customer's router, and any latency in your own infrastructure. If one is comparing to satellite or LTE, then this is basically amazing. If you're comparing to existing copper/fibre connection then it will have some effect.

I'm saying this having not actually deployed the hardware yet, just based on research.

Because of the distance we are from each other, our friendship has relied heavily on phone calls and video calls. Some time ago, we started calling them, "remote coffees", "\- Hey man, when are we having our next remote coffee?"

We met at the University, we spent about two years working for the same company and we have kept in touch during these years thanks to our "remotte coffees" and also due to the many concerns about technology and productivity we have in common. "This conversation should have been recorded!". We are sure this same thought came to you after some either formal or informal conversation you had. The challenge was simply to place a product live with as much free time as this quarantine allows, and here it is. We are not launching a super business, nor did we intend to, we both are fully dedicated to something else. We just wanted to launch this MPV and share it with friends and contacts.

We do have a lot more functionalities and ideas to put on it but, if you want to try it, those ideas will be much better by taking into account your honest feedback.

\- Web geo APIs to guide you to the next "treasure".

\- Webcam API to capture matching photo.

\- "AI" for matching photos and answers to questions in the backend.

\- the "AI" doesn't work well, planning to add a python Lambda with a better SSIM algo.

The hardest part so far has been permissions in iOS. If the user blocked geo permissions for Safari it is kind of a pain to enable again for a normal user. I haven't had a chance to test in Android yet but I presume that will present other challenges regarding permissions.

I've been working on my own browser for the last couple months, and decided that I can improve a lot when it comes to using the web for automating and acquiring knowledge (i.e. the semantic aspect of it).

Currently on the verge of founding a (possibly viable) startup with it, but the browser itself is totally alpha for now.

Been working on parsers and protocols for a while now, and had to switch to TDD to keep my sanity together. Needed to write my own test runner that can simulate network behaviours (2G slow fragmentation is real) and peer to peer scenarios. Most servers out there don't comply with specifications, so making my own client- or peer-side implementations work was a hard task.

Currently writing my own SGML parser and optimizer, so that the browser receives only "linted and upgraded" html that is free of malicious parts, whilst embracing the idea of disallowing everything that could be potentially misused, including CDNs that do cache busting all the time.

The idea behind the browser concept is that trust is not established by default, and users should decide what website to trust, and match that with what kind of content they'd expect the website to deliver.

 _> writing my own SGML parser_

How did you land on SGML?

What do you think of a browser/mode that parses markdown, so we can have a "markdown web" with less complex clients?

<comment><USER85> > Could you share more about this vision?

Phew, tough question. As I went into web development when XHTML 1.1 strict was the "cool shit", I kind of valued the aspect of using the web for acquiring and distributing knowledge. Not only for me, but also for publishing or other forms of media (e.g. by offering print stylesheets), screen readers, and semantic extraction of that kind of knowledge.

(I was also working on project(s) that were using DAISY to automatically convert websites into hearable formats to be consumable by blind people.)

Somehow from then (around 2000ish) to now, everything went to shit and nobody cares about that aspect anymore. News websites are too busy displaying ads and pushing subscription dialogs in my face (before I read a single line of their article) - rather than being readable or consumable.

And I kind of disagree with that. I want to make the web an automatable tool to acquire knowledge in an easy manner. And I hope I can do that programming- free. Currently, programmers can easily build scrapers - but imagine the possibilities once any person or kid can do that with a few mouse clicks.

I know there are a lot of proprietary scrapy-based solutions out there already, but honestly I think they're crappy. They see the web as DOM and not as a statistical model that a neural network "could" learn once you have a different way of rendering/parsing/modelling things.

> How did you land on SGML?

The reason why I am currently building my HTML(5) compatible parser with SGML ideas is because nobody closes tags. The spec is very complicated (especially while having an eye on what can be abused in the XSS sense or related security issues with CORS), so currently I'm kind of looking at a lot of parsers out there and try to find my own way of making this into a statistical model, so that in future my neural net adapters can optimize old HTML code into new, clean, HTML5 code.

> What do you think of a browser/mode that parses markdown, so we can have a > "markdown web" with less complex clients?

Actually this was my first idea to build this. I wanted to convert all html to markdown and back, so that it's easier and cleaner. The issue I realized is that most markup and meta information that comes with a website is lost in markdown (or commonmark), and layouting sometimes implies structure, too - <USER3> to how websites in wordpress (or any user-friendly CMS) are being built.

Code-wise you usually cannot imply meaning by only looking at HTML, sadly, that's why I switched to a "filtering proxy-like" approach, whereas the Browser UI simply receives the upgraded, clean HTML, CSS (and webfonts or other assets).

<comment><USER87> This is a subject I've been fascinated with recently. The web isn't nearly as good as it could be at gathering, networking, and assimilating information.

I feel that one key aspect of something like this would be the ability to annotate anything on any page you stumbled across, and to navigate between all your annotations in a cohesive manner.

\- Nvidia and CUDA stuff is so hard, I can't set it up properly no matter what

\- Tried YOLO but without CUDA and OpenCV I can't run it in video. Don't know how to fix it

\- Tried to copy other projects but can't find anything that I can parse with my amateur brain. I get lost and doesn't matter how many youtube videos I watch or stackoverflow pages I check, it's errors after errors after errors.

\- Tried in windows but that's not viable. Installing Ubuntu nearly broke my pc and somehow a virtualbox messes up the whole thing. Currently looking at this.

So yeah big mess, I'm way over my head and it's not fun anymore. But I still want to shoo away the pigeons and love the idea of learning more about DL/CV but guess I need to learn about the basics first, practice in other things before doing this.

I moved into a house late last fall, so I actually have some space to do so. This scratches multiple itches for me.

Itch the first: I've missed having a vegetable garden since I moved out of my parent's place and into apartment life years ago. While a small garden plot can't wholly replace the need to go to the grocery store for fruits and vegetables due to the inherent seasonality of growing food at small scale, it's damn hard to beat truly fresh fruits and vegetables that were picked not an hour before they landed on your plate. And any surplus left when the growing season is over can be preserved and stored for the winter.

Itch the second: It's _my_ creation, not my father's with which I am merely helping. When living with my parents, my father had his way that he'd like to lay the garden out. Granting that a man who grew up in a rural agricultural community probably knows a thing or about vegetable gardening, watching how he did stuff did always leave me wondering if there wasn't room for improvement. Since this is my garden, I can make my own experiments and decisions on how the garden is to be arranged, and what vegetables I want to grow (e.g dad loves beets; I do not). I've been reading about companion planting, and am eager to try things like growing corn and beans together, or growing chives near my peppers and tomatoes to keep aphids away (seriously, fuck aphids).

Itch the third: It lets me develop useful skills outside of my career in tech. While I have no delusions about quitting being a sys/net admin and going and becoming a farmer, I do think it's important to nurture useful skills outside one's main career.

Itch the fourth: I have something to automate with tech. Gardens _do_ need to be watered. Under-watering will limit your yield, but over-watering is also harmful to both the garden and the wider ecosystem of one's immediate area. There's a goldilocks-zone when it comes to watering, and the just-right amount of water depends on a number of things: what you're growing, your climate, the soil, etc. There is a real danger that before the close of summer, the garden bed will have an automatic, multi-zone drip irrigation system, complete with soil-moisture sensors, controlled by a Raspberry Pi or similar SBC.

During April I built a loft bed frame out of framing lumber. I can post about that too if any of you are interested.

<comment><USER97> Another tech thing it occurred to me to add to the garden. Some computer vision and a water sprayer to keep the squirrels off my corn and sunflowers.

That will actually be quite hard. I'll do the drip lines first.

Currently I'm working on an Electron app for automatically importing/managing screenshots and recordings from your Nintendo Switch, off the SD card. It matches the file name IDs (Nintendo uses these seemingly random IDs for each game) with the actual game name, moves it into a custom folder structure, etc.

My pick: [http://seriesreminder.net](http://seriesreminder.net) It was going to be the first choice when you wanted a new series recommended or just wanted to see which tv shows will air this week.

It was still using Rails 5 and Sprockets so I had to make the proper upgrades (including migration to Webpacker) and revamped the design using React and MaterialUI. I wrote an article about that [https://medium.com/@cionescu1/how- to-use-react-components-in...](https://medium.com/@cionescu1/how-to-use-react- components-in-active-admin-184ff63b378d)

Its goal is a combination of paprika ([https://paprikaapp.com](https://paprikaapp.com)) and Listonic ([https://listonic.com](https://listonic.com)).

I was continuously fighting my recipe planning. I did it for a long time in Google Keep. I can't manage recipes there, I have to add items to the shopping list manually. Changes in menu planning don't keep up with the shopping list, I forget to check the pantry. Etc. This time looked right to create something to mitigate the frustrations.

The technology is quite simple, it is a CRUD app in Flask with SQL backend. Everything is a docker container with data in a volume. UX is now quite limited, based on Fomantic UI. There is no goal to make it Saas, for friends I will just spin up a second instance.

I have been a software engineer for over a decade, but haven't been programming the last 5 years. Besides I am a fanatic home cook. So this looked like the perfect opportunity to have some fun again.

The original goal was a hardware device that's pre-programmed to work with a group of other devices where you just push a button to talk and it gets broadcast to the whole group with high quality audio.

First I'm starting with just a software version because cross-compiling for the pi-zero is kind of annoying.

Specifically, for those of us who either buy CDs or download tracks from the Web--the metadata is generally badly formatted, partial, in the wrong language, inconsistent from track to track, etc.

The hoped-for result is that you can run the tool on a directory and it will identify the files correctly and insert the metadata so that it is all consistent and correct. You can then copy the files to your favorite devices, and easily find what you want, make playlists easily, etc.

My current stage is researching the current tools, which are all (so far) partial solutions and IMHO cumbersome to use.

<comment><USER113> Neat. I implemented functionality like that for a media player, but it was years ago. The main issue we dealt with was the poor quality of the data, so I think we ended up with a combination of autodetect + store the original (incomplete) metadata so the user can always revert it if they find something wrong. Not a great UX, but GI/GO I guess.

<comment><USER112> Yeah, that is indeed a big part of the problem, as is anything that's crowd sourced. It's amazing in this day and age that the music companies themselves can't provide clean, consistently formatted metadata.

Are you actually rendering the SwiftUI components like VStack and HStack or "pretending" to?

<comment><USER114> I love working copy!

And yes I've thought about that, but I don't know how to share a file system...yet.

And it's real. I have a general solution for tricking SwiftUI to render different views at runtime. Some things are fake (such as photos) because I wanted it to work for a demo but I didn't have things like a file system setup.

Learning how to build sustainable trails, manage erosion, using proper grading on hills, and build fun features has been a great challenge. It's like extreme landscaping and woodworking combined. Then you get to ride your creation. I've been running the "operation" a lot similar to creating software with sprints, testing, and planning -- excepts sprints are hard labor, testing is riding bikes, and planning is waking up in the middle of the night with an idea for a new line.

There's a book by the IMBA (International Mountain Bike Association) that has extensive guides on how to create all sorts of features sustainably.

</comment><comment><USER122> Speaking of baked goods, I nursed a sourdough starter back to health. I found it in the back of the fridge where I'd neglected it for a couple of years. Poured off the icky gray liquid and scraped off the ugly top layers, and carefully got a pinch of relatively clean but inert looking dry starter crumbles from the bottom. I put that in a fresh jar and have been feeding it, and after a few days it came right back to life and is smelling great! Now to make some bread or pancakes with it.

My other project is harmonica karaoke. I'm not a blues player, I'm more into classic rock and country. Since I'm not that good at improvising, I like to take a song and work on it over and over again to work out a nice part and get the nuances just right.

One is Dreams by Fleetwood Mac, where I play the vocal lead with some jazzy stuff mixed in. I live a few blocks from Menlo-Atherton High School, where Stevie Nicks and Lindsey Buckingham met, so it's always fun to play one of her songs. (Harp: Lee Oskar F Major retuned as a high octave C Melody Maker.)

Another is Wagon Wheel, where I worked out the fiddle and organ parts plus some piccolo parts that I made up. (Harp: Lee Oskar A Natural Minor.)

My new lockdown song has been Atomic by Blondie. This one has been super fun! It took a lot of experimenting and trying stuff out, but I came up with an arrangement I'm pretty happy with. Now to beta test at our next Alteryx Got Talent virtual show! (Harp: Lee Oskar E Natural Minor.)

Maybe when we can all do it again, I will get to play some of these songs with other musicians.

<comment><USER61> There's a fair chance that you just made a new starter (from the flour you've been feeding your salvage with).

It's called Who Paid More ([https://whopaidmore.com](https://whopaidmore.com)) and the idea is pretty frivolous.

Think ranking and relative % across users for that period and the ability to share those results. Not much more to it at the moment.

To be honest, I wasn't really expecting anyone to ever be interested in my toy project, beyond spending a half hour idling their time, but a friend of mine has already started kicking the tyres which is very exciting, he's written a bot that scrapes the site and trades against it which I find hilarious.

</comment></comment></comment><comment><USER134> So for about two years I've been bouncing around an idea in my head to make the LZ78 compression algorithm (or more specifically, the LZString variant of it) compress better by forgetting the least commonly used substrings. I _think_ I'm just reinventing a mixture of LZC and LZAP (or LZMW), but the on- line literature discussing either algorithms in detail is abysmal[0][1][2]. The main innovation would be that I have a fairly simple way to implement the forgetfulness.

Another separate innovation that I have in mind is combining that with a special run-length encoding sequence that, due to the interaction between LZAP and run-length encoding, actually wouldn't encode runs linearly but exponentially[3]. That is, instead of _" repeat substring X for N times"_ it would say _" repeat substring X for fibonnacci(N) times"_. I suspect that might actually be a novel innovation!

Aside from a lack of time and energy, the main thing holding me back has been, and I'm dead serious, off-by-one errors. It's really, _really_ easy to screw up the order of adding new entries to the dictionary on both the compression/decompression side in such a way that you just get garbage out, and it's a pain to debug.

If my algo turns out to be original, I'm tempted to call it LZWAN, or _Lempel Ziv With Amnesiac Nodes_ (referring to the nodes in the trie used to grow the dictionary).

If you're thinking about doing the same, for formats and media, I settled on:

DVDs: yes, they're old, but they support more resolution than VHS, and practically every new Bluray player still plays them. Also, DVDs support 352x480 resolution. It's still more than VHS, and you can squeeze more content on the disc or encode it at a higher quality.

VP9+Opus+webm on a DVD. This codec/container combo is supported by Firefox, Chrome, Windows Media Player, and Android, so while new, I expected it to be supported for a long time. AV1 looks promising, but probably not ready.

I'm not bothering, but for iOS, use x264 and AAC in an mp4 container. Those were the only modern codecs and containers I got to work. Also, Apple, x264 and x265 are good, and all, but there's no excuse to not support VP9.

I'm saving the unencoded files as ffv1/flac in an mkv container.

For the actual DVDs, I'm using MDisc archival media.

I honestly haven't figured out what I'm going to do with it long term, whether to make it free or to try to monetize it somehow. Right now, my main goal is to fold it into an Electron app and have it sync with a Couch/Pouch db server once the main UI code is done.

So I created such a stack - the Knests stack ([https://github.com/tudorconstantin/knests](https://github.com/tudorconstantin/knests)).

I actually started to work on this in December, but I published it a few days ago.

Please beware that in order to use it for your projects right now you'd have to be quite comfortable with the nodejs ecosystem because the whole stack is not quite tidied up.

<comment><USER138> I am also working on this! I used Node a lot 5 years ago and not much since, so I'm coming up to speed on TypeScript and various other things. I'll check your stuff out. I may throw mine away.

I love a lot of things about the Node ecosystem, but the fact that being out of it for 6 to 12 months means you fall behind is not great.

<comment><USER137> The main components I used, are: NestJS with Express as an app server, KnexJS as a query builder (because people seem to not like TypeORM that much, it lacks migrations and you have to go pretty fast to custom SQL queries), NextJS for the UI.

Yeah, I totally feel you with falling behind regarding the full-stack web dev with node/react, the pace is incredible.

<comment><USER138> > _people seem to not like TypeORM that much_

I started down the road with TypeORM for my starter, and I ran into several pain points. I was reading the Knex docs last night actually, heavily considering switching. I also wrote a quick `pg.ts` file to just use node- postgres directly, but the lack of migrations is just too painful. I looked at db-migrate briefly but didn't come to any conclusion.

So that's a long way of saying, I think Knex was a good choice. Provides migrations, handles connection pooling and transactions, but doesn't deviate too far from SQL.

If all goes well I should be getting an EverDrive-64 X7¹ in the mail in a couple weeks, which will be a boon for (hopefully) eventually putting all that reading into practice. No practical benefit to this _per se_ , but it does seem to be an interesting potential foray into embedded programming, which has always been a gap in my knowledge that I've wanted to fill.

I've also been on-and-off learning Zig, both in support of the above (Zig on the N64 seems to be uncharted territory that I'd love to help explore) and in support of development of a Tcl-like programming/scripting/config language (iterating on my learnings from an earlier project of mine² implementing such a language on top of Erlang/OTP); the latter's something that's been bouncing around in my head for a few years now, and I feel like I'm at the point where I'm ready to start bouncing those ideas into an Emacs buffer, lol (especially now that I've found what seems to be the right host language in which to implement it).

EDIT: oh, and early into quarantine I did submit my first ever patch to wine- staging³ (with quite a bit of help from a couple others, including one of the wine-staging maintainers) to fix a mouse cursor/movement bug in Mount & Blade II: Bannerlord under Wine/Proton. It's a small patch, but it's my patch nonetheless, and it's a surreal and proud feeling to see my name in the commits for software I use almost daily. It's also helped demystify Wine a bit for me, and I look forward to continuing to do my part to make it better.

<comment><USER142> As someone doing mostly C development at work I've really come to enjoy Zig in my side projects at home. At work we are moving a lot of newer development to Rust, which makes sense in terms of safety, the speed we want from C and "modernising"/becoming more attractive as an employer. However, when I'm doing projects for my own amusement at home I want something that doesn't feel like work, and getting into Zig and have something working took me no time. It's so easy to interface with C libraries that I can spin up most things with existing C libraries for the things Zig doesn't already provide itself.

<comment><USER141> Yep, exactly. I was originally pretty excited about Rust, but I feel like it biases toward large highly-structured projects like C++ does, making it a bit daunting for personal projects. Just a bit too professional for something I'm hacking together over a weekend, lol. Zig feels like it's easier to wrap my head around, and seems optimized for the "pet project" use case.

I also feel like learning Zig is helping me better understand C. I probably wouldn't have been able to contribute much to that Wine patch if Zig hadn't already gotten me more comfortable with pointers, statically-allocated variables, and such in a reasonably-safe way (having prior experience with Perl did help a little bit for pointers, since referencing and dereferencing variables is pretty common in Perl codebases, but it always felt a bit detached from what the machine was actually doing behind the scenes).

</comment><comment><USER145> I've had a feeling that certain state scratch off lottery games can be beaten thanks to certain actions the states take in the name of transparency. For example, they publish daily reports of the number of prizes remaining.

A simple example is imagine a game with 10 tickets sold for $1 each and a single $9 grand prize.

If 1 ticket is sold each day and if the lottery publishes the number of remaining winning tickets each day, then you can just wait 1 day and if 1 ticket was sold and 9 tickets remain and the prize wasn't claimed, well now there is a 1/9 chance of winning $9 and the expected value is even.

I started scraping several state for daily numbers and calculating the expected value of each game. Every now and then one gets over 100% EV. (Not taking into account annuity discounts and taxes)

Kudos for not over-complicating the product in some weird struggle to find the one key thing that users would pay for and find a way to insert friction there, but of course that means you don't have a near-term way to get paid for your work either.

As I type this, i'm flipping 3.5" floppies from the early 1990's I've had stashed away in a closet for the past 25 years. Its mostly automated. I'm using a high speed floppy drive (with laser tracking) to image the disks. Then I mount them and copy the files off to the NAS. The drive also has a soft eject (like all the old mac drives). So it just sits there buzzing away until its done then it ejects the floppy. About every 40 seconds or so I pick it up, and stick the next one in the pile in.

Working from home puts this within arms reach all day long. So while sometimes I get really busy and ignore it, when I become aware of it I start flipping floppies again. Once every few dozen floppies when a label read fails/etc then I type in a new disk series and let it rip.

I did all the music CD's a few years ago, most of my 8x10 photos last year (the fastfoto 640 is awesome, it needs a bigger feeder though).

Next up are the 5.25"s, and a bunch of QIC80 tapes I used like floppies in the mid 1990's. I've also got a stack of harddrives from the past ~30 years I need to capture.

Of course I've got the usual set of small projects as well, but I have to be careful about doing those because I can accidentally lose a day that I should be doing actual work i'm getting paid for. The flipping floppies/etc is a good background no brain activity.

It's been a great learning experience in the world of Supply Chain Manufacturing. While the site was an initial success and led to dozens of orders the first week (with no paid advertising), I hit a major roadblock that I was not expecting. My suppliers had to temporarily halt equipment manufacturing due to the emergency law that required them to start producing PPE. This led to the shortage of gym equipment nationwide. You can't even find dumbbells online.

Although my website got a lot of organic traffic and orders within the first two weeks, I was unable to fulfill most orders since manufacturing was on pause and everything was already sold out.

Since then I've continued studying SCM, and I'm also learning Python so that I can build a model to predict this kind of event in the future.

So far so good, it's pretty good to play now, still need more action regulation. The piano had been stored on its side for years, lots of transport, water and insect damage.

Current project: Intermezzo no. 6 by David Benoit: [https://open.spotify.com/track/0MJ4ikwkXV4lJiRjklWhS9](https://open.spotify.com/track/0MJ4ikwkXV4lJiRjklWhS9) (sorry, can't find a youtube link).

Total spent: $100 for the piano, $100 to transport it, $50 to buy string steel to replace the strings that had broken. There is still some worn felt in there as well that will need replacing, mostly on the hammer rest bar and the bottom of the jack support bar. Shaping the hammers was a tricky job (they'd worn down quite a bit, to the point where the original shape was hard to determine).

All in all very satisfying.

<comment><USER56> I'm guessing the piano is in pretty bad shape?

Generally, people don't realise that pianos that don't get restored have something of an expiry date. I know that if it's 80 years old and has never been restored, then it's considered to be unusable. But I guess if you put in really hard work one can? Conversely, old pianos in good shape sound great. I think that's my issue with Yamaha grands. They sound soulless.

Steinway pianos for example have to be restored with Steinway parts to have resale value. I guess that's why you get such high prices for them.

<comment><USER153> > I'm guessing the piano is in pretty bad shape?

Well, it was!

> Generally, people don't realise that pianos that don't get restored have > something of an expiry date.

Agreed, especially once the soundboard or pinblock are cracked.

But those are actually quite good on this particular instrument. It was simply a 'budget' grand, 135 so fairly small, made in the DDR so not the best quality (to put it mildly). The fun is in getting it to work again and a great piano to practice repair skills on, you couldn't possibly mess it up much further.

> But I guess if you put in really hard work one can?

Absolutely, but it would definitely not be economical, then you'd have to work on a more valuable instrument.

> Conversely, old pianos in good shape sound great. I think that's my issue > with Yamaha grands. They sound soulless.

I'm not good enough to distinguish from a technically good grand and one that sounds 'great', this one actually sounds a lot better than it's $100 price tag would lead you to believe, in fact it sounds a lot better than my $1500 digital one, and it's in many ways much more fun to play.

> Steinway pianos for example have to be restored with Steinway parts to have > resale value. I guess that's why you get such high prices for them.

Steinway pianos are valuable because they are sought after, not because each and every one of them is great. I've seen really crappy Steinways sold for their weight in gold.

Bosendorfer is very good too, not nearly at the price of a Steinway, Pleyel has some really nice instruments (but those are getting much older now), Fazioli, Kawai and many others. The history of a piano is about as good as the trees from which its parts have been cut and with wood being a natural product that puts a lot of variability in at the core.

That's why the really good brands pay a premium for the highest grades of wood, that's the easiest way to make a huge difference in quality.

<comment><USER56> Stellenbosch University has Bosendorfers in the conservatory. They are great!

I also almost had the opportunity to buy a Pleyel for cheap, but I think a dealer bought it straight away after it was posted.

If I had that kind of money I would go for a Fazioli these days. The story behind it and the niche of an Italian piano is just too enticing. I would go there and see the whole thing though. And of course if they don't play well with my style then... Well, then one always has the classic brands to consider. The other awesome piano is the Bosendorfer with the extra lower octave. Bosendorfer is actually now owned by Yamaha.

As a movie buff, I'm often frustrated by the film recommendations apps that return results too out of context for me. I also find them quite depressing, they're often nothing more than echo chambers that favor the same movies again and again.

Actually, I didn't become a movie buff with tools like this but with watching the movies liked by the directors of my favorite films. For instance: Pulp Fiction -> Quentin Tarantino -> Bande à part -> Jean-Luc Godard -> Robert Bresson -> ...

In addition to giving you some ideas about films that you could like, this helps you to better see the big picture (no pun intended). You learn about the important movie periods and movements (French New Wave, Italian neorealism, New Hollywood...), you develop a more serious approach to film, and you can live these mind-blowing moments when you notice similarities between two movies done 50 years apart and that looked at first glance totally different.

I already created the engine (which is giving good results for my profile! It recommends me movies that I never thought of). The challenge was mostly to found all the data required by the engine. Now, I must admit I'm procrastinating a little bit for developing the actual web app!

Example menu: [https://www.weekmaal.nl/public/4fc17e55-cc39-4a4e-b6cf-79c1c...](https://www.weekmaal.nl/public/4fc17e55-cc39-4a4e-b6cf-79c1c39ee020)

Warning: Only available in dutch!

I was doing weekly groceries since last summer and had partially automated the process of aggregating the ingredients into one grocery list already.

When the social distancing started I figured maybe others would find this tool useful, so I spent a couple of days building a usable interface and account creation features and told some friends on Facebook. Nobody, besides me and my girlfriend, ended up really using it, but it was a nice exercise nonetheless ;).

<comment><USER187> Nice! Do you know if it would be possible to automatically get the recipe list into something AH, Jumbo or picnic delivery?

<comment><USER186> Thanks! As of now, no, but I'm thinking about adding such functionality with a chrome extension maybe, not sure yet if that really works out or if I get round to it though. But its currently my biggest bottleneck in my own workflow so it may just get there ;).

My ambition is to plan out for 3 months or so and then to be able to split up the groceries and order all the non-expiry stuff once from a grocery delivery shop and have a weekly grocery list to take to a bio shop.

* stealthcheck[0] - Service health monitoring with email alerts and automated restarts in <150 lines of code. Just create a checks.json config file where each check includes a check command, interval, and on-fail command. Set up multiple stealthcheck instances all pointing at each other for redundancy.

* quarantest[1] - Most CI testing tools focus on automated tests, but sometimes the changes are very visual and you just want to give your team a demo of your pull request to play with. quarantest runs a build for each GitHub PR, generates a URL for the build, then posts a comment on the PR with a link to the build. You can see an example of it in action here[2]. Still in a pretty hacky state. Probably would be better to use the GH status API with a link that goes to a page listing all the past builds from the PR instead of spamming comments, but it's getting the job done.

I created [https://fruitionsite.com](https://fruitionsite.com), a free, open source toolkit for building websites with Notion. You get pretty URL slugs, custom domain, and a whole bunch of other features.

I hacked it together in a weekend, put up the marketing site (using Fruition, oh so meta) and shared it in Notion's Facebook group and subreddit, without any expectations that it would go anywhere.

The response has been incredible. 11000 people have checked it out since. It ended up on the Product Hunt newsletter [1]. People are making YouTube videos [2] about it. Chris Coyier of CSS-Tricks [3] shared it too.

The biggest lesson for me was just launch it. There were many more things I wanted to add. But I decided to share it publicly before it was perfect. Now I have users who can give me real feedback rather than me pretending I know what people want.

</comment><comment><USER191> I created [https://www.pullchecklist.com](https://www.pullchecklist.com), a Github tool that surfaces contextually relevant checklists for Pull Requests. I built it to scratch an itch of a common problem at work. Some of the member of my team were tired of manually checking Github checklists because they were not relevant to the PR they were reviewing. This tool layers conditional logic on top of Github's checklist functionality.

</comment><comment><USER192> Fixing data access for C# :-) [https://marketplace.visualstudio.com/items?itemName=bbsimonb...](https://marketplace.visualstudio.com/items?itemName=bbsimonbb.QueryFirst) This, I humbly submit, is superior to _all_ the existing approaches, in terms of developer speed and comfort, runtime perf, and testability.

Compared to EF, you author your projections in a sandbox where you can get familiar with your data as you build up your projection. Compared to stored procs, your queries are versioned and distributed with the app. Compared to Dapper and ADO, your SQL lives in a real environment and you have zero mappings to maintain. This ought to change the world, no?

</comment><comment><USER193> I've setup a personal matrix[1]-instance, with the relevant bridges for almost all communications-platforms I use. Only exception is Signal, which ironically is open-source, but still somehow un-integratable.

Being able to access all my things, consistently in the same app, across devices, machines and networks is super-neat, and Riot[2] is a really smooth Matrix-client, on mobile, web and desktop.

This is without a doubt the most productive spare-time hacking I've done in a good while!

<comment><USER194> :D does [https://github.com/witchent/matrix-puppet- signal](https://github.com/witchent/matrix-puppet-signal) not work?

<comment><USER193> Nope. At least not for me.

I had the synapse-instance, plus VoIP, irc-bridges, whatsapp and facebook bridges all up in about one day.

The Signal bridge? It's an absolute train-wreck to setup, and after spending a good whole weekend++ getting everything building...

Then I found out that the "pair" command never completes. By random I later found out that it only works for the other users which has an _Android_ phone. Seemingly it doesn't work if you use an iPhone to pair up, but that's not documented anywhere either.

I find it particularly interesting comparing that to the bridges for other proprietary IM-systems (facebook, whatsapp), because you would expect those to perform worse (being closed, need reverse-engineering, etc), but no. They are seamless to setup, while open-sourcey hero "Signal" is impossible to create an integration against.

Pretty unexpected and weird.

I'm curious how devs with kids at home manage the current situation. The constant multitasking stresses me a lot, I feel incapable of doing anything tech-related that would involve deep focus.

Does cleaning up the flat count as side project :D?

<comment><USER196> Same. I've no idea how people with kids and others to keep happy are managing to squeeze in side projects.

<comment><USER197> I have a full time job that has moved to remote and my spouse is on Zoom calls most of the day for work. The only "side project" I have time for is managing my kids' remote learning. They are 7 and 9 yrs old. There are so many links and logins and forms and downloads and uploads. I've learned. Lot about how Google Classrooms could be redesigned to improve independence of younger learners. Candidly, this is very difficult and my mental health is taking a serious hit.

<comment><USER198> I feel like I need a holiday, a few days off at least. Doesn't feel smart to ask for time off though and I don't really want to waste it either.

<comment><USER195> Well, I don't know the policy of your company, but at mine we've been encouraged to take some days if possible.

Not only for mental health, but also to avoid that everyone take time off at the same time. On another hand we have 30+ days per year, I guess it's a different story if you only have 20 days or less.

<comment><USER197> I can take time off and I did last week. However, I ended up just doing pretty much the same thing as when I was working, so it was a waste. What I really need is some time completely to myself, just sitting outside or something. It's my most precious resource right now and very hard to come by.

</comment><comment><USER200> After falling in love with the Destroy All Software style of genuinely advanced, all-encompassing programming screencasts, I started a YouTube channel with my own twist on the theme: Screencasts situated inside a decade- old, profitable, production web app, ones that emphasize actual workflow.

I've been an indie-hacker for 10 years so have seen the effects of my programming decisions over the same period. I've seen how fads come and go, sometimes wreaking havoc. I've also seen how coding decisions affect business (such as strategies to transform data into seo at scales of 10k+ items). I've seen how to keep something running day-and-night as if your livelihood depended on it - since it very much does.

That's the game plan anyway. I'm five episodes in: [https://m.youtube.com/channel/UC17mJJnvzAa_e9qQqLIfIeQ](https://m.youtube.com/channel/UC17mJJnvzAa_e9qQqLIfIeQ)

I published an article about Zettelkästen: [https://github.com/alefore/weblog/blob/master/zettelkasten.m...](https://github.com/alefore/weblog/blob/master/zettelkasten.md)

I'm also working on an article about software correctness, summarizing my experience working on infrastructure software at Google for about 13 years. It's very incomplete and I'll probably end up restructuring it significantly (not very happy with the current logical structure). I only started working on this two or three weeks ago (as a side project), so I'm satisfied with the progress I've been able to make: [https://github.com/alefore/weblog/blob/master/software- corre...](https://github.com/alefore/weblog/blob/master/software- correctness.md)

I'm also working on other similar articles on other topics (Bitcoin, Stoicism, Bauhaus), but those are even less complete.

Lastly, I've continued to make significant improvements to my text editor ([https://github.com/alefore/edge](https://github.com/alefore/edge)).

I think it's interesting that I'm finding it hard to focus on some topics, but I'm currently very productive in others.

<comment><USER210> I started practicing Zettelkasten recently, using The Archive[1].

I already had a pretty large collection of less-structured notes from nvALT, and I love how the new "rules" really help to shape my new notes. I'm converting old notes as I have the time and need.

I was initially skeptical of the idea of timestamping notes in the filename, but I find it counterintuitively useful, and The Archive has really good support for it w/ the Cmd-U shortcut. The Archive also has multiple tabs, which help immensely over nvALT's single pane.

[https://insightfulinteraction.com/](https://insightfulinteraction.com/)

<comment><USER212> Great job!

People often insist that JS is necessary for interactivity, and it really, really isn't. You can create interactive web experiences without JS, and just add sprinkles of it when it makes sense.

"Basics" are more than enough for the vast majority of web content.

<comment><USER211> Thank you! I agree -- most sites on the web are just content and there's no reason to have excessive JavaScript or any reason why the page can't be perfectly functional without it. Some people call it 'The Website Obesity Crisis'.

</comment></comment></comment><comment><USER213> I started taking a few bites out of a job shop scheduling solution that's been in the back of my mind for ages.

I tend to end up doing general geek stuff for small manufacturing businesses. At a certain point they always ask about scheduling automation because their one person who runs the shop can't keep track of everything any more. The existing scheduling solutions are either too far down the rabbit hole of job- shop-scheduling yak shaving to fit or attached to an ERP that's out of their price range for a while.

In this case scheduling automation doesn't have to be perfect. It shouldn't be, it's a waste of time. These users haven't grown into habits that fit an optimized solution; their manufacturing data has been treated as an arcane nuisance because it hasn't provided benefits yet. All they need is something basic to get them started on the way to better habits and improving their data while improving scheduling. I don't know how far I'll get, but it's cathartic and educational to work on for now.

</comment><comment><USER214> An app to connect women travelling solo.

I've seen women posting on solo travelling facebook groups their current or next location and PM each other, especially in non-english language groups.

With the app, you would receive a notification when a new traveller (speaking your native tongue or not) is close using geolocation, then you check their facebook profile and message them (via messenger).

No need to display the app: you just wait for the notifications (which frequency can be changed). This is my idea for solving the egg & chicken problem, so obviously the app doesn't display ads (and is free).

<comment><USER129> Interesting idea! I bet there are tons of solo women travelers who would love this kind of thing. How do you verify that they're all women?

so, get a meat probe. [https://www.thermoworks.com/Thermapen- Mk4](https://www.thermoworks.com/Thermapen-Mk4) is the best one, thermoworks also has probes that you can use the entire cook.

It reports detailed information about the error like console logs, code snippets, stacktrace, occurrences with timestamps, previous user interactions and custom data. In addition, it allows you to track data about your websites visitors such as page views, unique visitors, sessions, time on page, referrers and device data. It's all done in a very transparent manner with as little data as possible. It's written in Go and React and is completely open-source and can easily hosted by yourself.

Operating under the codename Portobello for now but friends and family don't like the name. The landing page is atrocious, but the actual app functionality is nearing an MVP.

I guess the big question for me is do I make it realtime for the launch. The handshake for swapping keys and allowing access to a board/organisation currently happens via HTTP polling, but that's not such a nice experience. Currently the whole thing is hosted on Netlify so moving to websockets would require me to set up another service somewhere, not sure if it's worth it before I validate my idea.

I'm going to do an official launch on Hacker News within the next couple of weeks. Still a lot to do as you'll see.

The idea is to find interesting content that's only available in English, and translate it to make it available in Spanish, while at the same time providing some tools for language learners. This came out of my own efforts to find content in both languages to help me learn Spanish. So we display posts in both languages and if you click on a sentence it highlights the same sentence in the other language. Right now it's just the boilerplate next.js + strapi (headless cms) that I found, but we're in the process of coming up with a proper design.

</comment><comment><USER235> I've been working on Flux, a platform to deploy and host deep learning models in production.

Instead of renting a GPU instance and setting up a Flask web server, you use git to push your trained model to Flux with some configuration and get back an http endpoint.

For example, you set that your input is the url to an image, and that your output should be the top classification and its likelihood, and that your model is in pytorch.

For example if you have a classifier for dog breeds you:

Make a POST to fluxdeploy.com/username/dog-classifier with json { "url": "..." } And get back { "klass": "Great Dane", "probability": 0.937373 }

No need to do your own devops, Flux will scale for you. And it's priced per- request and cheaper than hosting your own web server. Flux also deals with versioning and dependencies.

Still working on streaming inputs like video.

The app itself is a bit of a different take on the problem space than many of the other well-known offerings in the market. iOS only for now, SwiftUI, and built around enabling "Compelling & Comprehensible Input"-based language acquisition using video, audio, and text you've supplied yourself.

Interestingly - when I started the project I reckoned it would be about 2 years to shipping something useful, which would mean about Q3/Q4 2020. I'm starting to think that estimate was, shockingly, about right.

More seriously, I'm trying to get in the habit of not talking about any side project I've not shipped yet, since when I "announce" them in advance I end up not shipping anything. Turns out this might actually have a basis in science, as recent studies allege that the brain "discharges" some energy/motivation when one talks about future plans.

<comment><USER242> I read that too some time ago. I understood that once you announce your project, you get some of the social credit for it. This "advance credit" diminishes the return on actually putting down the work, which also tends to become more tedious towards the end of the project.

I observed this with myself: many years ago I was planning to write a novel. I had already sketched out the plot etc., and of course told my friends a family about it. For about half a year, they kept asking me about the progress. In retrospect, I quite enjoyed being "an author" in their eyes. It seems I did benefit from announcing my project without actually ever finishing it, which may very well have lowered my motivation to pull through with it. Anecdotically QED, I guess...

<comment><USER243> It's interesting that you felt impacted by their admiration, while they likely saw you as faking it and waiting for you to step up or admit defeat.

My vision for the project is to give learners the basic foundation of vocabulary, kanji, and grammar and to expose them as early as possible to native content (something that I wish I did sooner). For that reason, I utilize various media such as tweets and YouTube videos to make the content more natural (i.e. not textbookish), relevant, and engaging.

The project is still far from completion. A few days ago, I shared the early version of kanji module ([https://xn--wgv71a119e.app/漢字](https://日本語.app/漢字)) to a reddit community. If you are interested in the details, please check the post below:

</comment><comment><USER293> Building a weightlifting workout tracker, as a mobile PWA: [https://www.liftosaur.com](https://www.liftosaur.com)

There're a lot of apps that are either focused on one weightlifting routine (like 5x5 StrongLifts or Five3One) - they do nice job leading you through the routine, but if you want to try another one, you basically need another app. And if you want to create a custom routine, you're out of luck. There're also generic ones, like Strong or Jefit, but it's hard to make them follow some specific routine, increasing and decreasing weights automatically, changing exercises when necessary, etc.

I thought - how hard would it be to create a platform, that'd support many routines, and you'd choose any, and have a consistent UI across them you got used to?

Another thing I wanted to see - how hard it is to create a PWA app that is nice to use, and what features are still lacking there (compared to native experience).

The app is already in a usable shape, I use it 3 times a week, though it only has one working routine now. It's written in Preact/Redux/TypeScript.

It's a surprisingly pleasant experience to have a personal project like that, and slowly build it in your own pace, working on features you care, that would actually help you in your workouts. I found myself sometimes working on it til late night, being in that "flow", like in the beginning of my career, having so much fun, and returning back the joy of coding!

For example, you can have everyone in the meeting speak one after the other (the app handles muting and un-muting the right people), then repeatedly shuffle people into pairs so that everyone gets to talk 1-on-1 with everyone else. Or have a "speed-dating" style format for the first 20 minutes of your remote meetup, before bringing everyone back to the main room for the main speakers.

Barely ready to open it up yet, using it to host daily "standups" with my friends, but going to have a few friend gatherings with it later, and maybe a local meetup. The friend gathering will have the first schedule I mentioned above; have everyone speak in a circle to catch up the group on what they've been doing, then split the group into pairs (shuffling the pairs). The meetup will have the "speed-dating" \+ switch to main talks.

Uses Jitsi for the hard video webRTC stuff, and then nextjs with socketio for my application.

On gitlab at [https://gitlab.com/amedeedabo/flexichat](https://gitlab.com/amedeedabo/flexichat).

Getting back into React and ES6, and all the amazing new CSS stuff of the last 5 years!

Eventually I want to split it off so that the logic can be in its own package, to make it easy to integrate different speaking formats into different, existing apps.

Have you thought about an option to gamifying it a little bit by letting the user guess which direction the headline leans? And then revealing the direction and the news source.

For example, when the "enable bias guessing" switch is toggled, there's a slider that appears on the bottom of the headline. Or, simpler, just two buttons that say left, right. You can guess all of the headlines on the whole page, then reveal and see how you did.

<comment><USER298> I like the idea of getting user feedback and gamifying the site a bit. It also might be interesting to take the bias guess results and show where on the spectrum of left to right site users think a headline falls. Thanks for the suggestion!

I found all the existing time trackings apps to be so bloated with features like invoicing, billing, teams, etc. I wanted something for myself to be able to keep track of how long I was spending at work and on various tasks.

I'd love any feedback!

</comment></comment><comment><USER302> Now that everyone is working remotely, it's much harder to get to know your teammates. I built [https://gettoknowapp.com](https://gettoknowapp.com) as a Slack bot extension that sends you 1 question every M/W/F and posts it to a dedicated #answers channel. The whole app is contained within Slack - you can view people's past answers, upvote/like them, and the real fun is just seeing what your friends/coworkers had to say that you didn't expect about their answers.

I had used apps like Donut before and they felt oddly pushy and impersonal; you join a room and Donut will randomly select people to chat. Have you ever been in one of those arrangements? Extremely awkward openers. I wanted the questions to serve as a fun icebreaker to help people naturally discover interests together.

Oh and of course the tech. It's all built on Elixir. I run one web server and one database server and that's it. I already have about 100 communities spanning about 4000 people so in terms of message/event processing it is completely seamless...one of my favorite things about Elixir. Most interactions are processed in measure of microseconds rather than milliseconds. This makes for a real-time experience in Slack and is such a joy to work with. I also contribute to the Elixir-Slack open source project which has been fun working with as well.

I hope to incorporate more user feedback as it grows but so far it's been a great tool for teams in lockdown as they ramp up new people and want to quickly build them into their teams' culture.

Snowdrift.coop is a crowdfunding platform specifically for free/libre/open (FLO) public goods -- freely-licensed software, music, journalism, research, etc. It's based on a new funding mechanism we call Crowdmatching, where patrons pledge to support projects with a monthly donation proportional to the number of others making the same pledge ($1 per 1000 patrons).

We operate as a non-profit cooperative. The site itself is free software, written in Haskell (yesod) and we've also tried to stick with FLO tooling whenever possible, although we made an exception for hosting our source code, which is at [https://gitlab.com/snowdrift/snowdrift](https://gitlab.com/snowdrift/snowdrift)

Of course, as a free software project, we suffer from the same funding issues we're trying to solve. The project is currently a 100% volunteer effort, and we're making slow (but nonzero!) progress towards our initial launch, when we start hosting our first outside projects.

One of our biggest bottlenecks right now is developer bandwidth. We have a handful of updated designs that address UX issues with the live site, and need to get them implemented -- if you know css, haskell, or both, we'd appreciate help!

In addition to replying here, you can also reach out on our discourse forum ([https://community.snowdrift.coop](https://community.snowdrift.coop)), irc/matrix (#snowdrift on freenode, bridged with #snowdrift:matrix.org), or gitlab (above).

<comment><USER320> A little more detail, to avoid overloading the parent comment:

Currently making html/css changes on the site is a little bit painful, because they're the kind of thing that you often want to make small tweaks to until it looks right, and yesod is fond of rebuilding lots of stuff on each change.

To continue making forward progress while we've been short haskell devs, the design folks have been iterating on a prototype using a static site generator. Several of the new designs are static pages, so in theory it should be a mostly cut-and-paste job to move them to the real site. However, the css "framework" (ie, sass mixins) of the two have diverged a bit.

So, there's a number or ways in which progress could be made. In order from most long-term impact to fastest immediate progress:

\- Haskell-side improvements to make the site build faster, so the designers could work directly on it for static content.

\- Getting the site and prototype css back in sync, so that static pages can just be dropped in.

\- Migrating individual pages from the prototype to use the main site css instead.

If you're interested in other aspects, there's governance, legal, and a few other miscellaneous tasks, too.

I read five pages from a book that interests me every day and then write about my interpretation.

To build a good reading and writing habit, I built a static blog using JAMStack technologies.

[https://5pagesaday.com/](https://5pagesaday.com/)

I used Hugo to make a static site and Netlify functions to call Google Book API, Forestry dot io to write my book blurbs every day. I integrated Amazon ads to implement related book recommendations. I use netlify to host and Github actions for CI/CD. It's a PWA out of the box and supports Google AMP.

The cool part is when writing a book experience, I provide the book ISBN, and my netlify function would go and grab book cover gif, description, author name from Google Book API automatically :-)

I am really pleased. I will start reading and writing from the coming Monday.

Wish me luck and follow me to encourage. I will open-source my Hugo theme which I named "Morning Pages" and my blog on Github later this week. Cheers

\- A task-executiont tool, a bit like make ([https://github.com/rberenguel/paque](https://github.com/rberenguel/paque))

I have also brushed up on D3.js (for a project which hasn't appeared yet, but the result will also be used for the notes graph as an alternative to Graphviz) and generative coding (using p5js and threejs, the latter for fragment shader fractal stuff, [https://github.com/rberenguel/sketches](https://github.com/rberenguel/sketches), most are still not up there, but only around my twitter feed). The generative coding path is also taking me towards tone.js and ORCΛ, but so far I have only dabbled in them.

We believe that managing the game is big part of having fun. Games will have integrated video chat and can play with friends like real life.

This is still an early stage. For example, we haven't opened up to users adding their own games yet. We added some games to test our platform. We are working on adding more capabilities to enable more games.

I noticed that more and more companies were doing business over chat. Customers are clamouring to give them money over WhatsApp, Instagram, Telegram and Messenger, but these chat platforms are not designed for trade. Bridge is.

After getting into this, I've found out that there are a literal crap ton of people selling fakes and it is extremely hard to prove the source of the masks so I've been doing everything possible to provide transparency in the supply chain (including having customer names added directly to production contracts with the manufacturer).

PSA: KN95, N95, FPP2, and other NIOSH certified masks coming out of China are at a minimum around $1.5 per mask FOB (meaning to the manufacturer) then you have to get the masks into America with import taxes, ocean or air freight and then local last mile delivery and warehousing. That easily can add $1 per mask. My point, if anyone is selling masks for <$2 per mask in small quantities, they are probably fake. The raw material cost alone has skyrocketed for 99% material that is used in the production of >95% masks.

For example, our cost to reliably (~20 days) get 2M masks landed in the USA, ends up being $2/mask. That's without any profit and not including local delivery.

Happy to answer any questions! firstname.lastname@example.com

<comment><USER353> The claim for N95 masks is not that they are effective for 95% of people, it's that they filter out 95% of small particulate matter. The remaining 5% may or may not be enough to infect anyone, or 5% of those wearing, or 100% of those wearing.

The manner in which you would make a legal claim that the product is not as advertised is to take the mask and use the same certification process the manufacturer claims to be using to test efficacy.

<comment><USER352> Ah I knew that but didn't run the implications right in my head. Thanks for the correction.

</comment><comment><USER355> As I mentioned in a thread earlier today, and at the urging of some friends, I am working on the 0.1 release of my personal programming language.

It is a language based on explicit parallel and sequential composition of expressions (very similar to the concatenative languages family) with an underlying categorical semantic/type theory based on Adjoint Logic (work by Pfenning, Reed,Pruiksma et al and work by Licata, Shulman, et al with the Simple Intutionisitic fragment replaced by a Dependently typed fragment (ala Krishnaswami) and all based on work in the '90s by Nick Benton).

I set myself a goal since I'm in lockdown of having a landing page with minimal compiler and hopefully a small web based playgraound published before July 1. I have really been enjoying the work I'm doing on this and hope everyone else is having a good time working on their stuff amidst all the external upheaval.

</comment><comment><USER358> I've been trying to become a better Clojure programmer, so have been attempting to use Clojure and Clojurescript almost exclusively for my side projects, especially since I don't use it at work. First I built a real-time version of the board game Gobblet, a pretty cool two-player board game I learned about recently (Kinda like Connect 4 with a surprisingly interesting twist). After getting it to the point where I could play with my friend over the internet I moved on. Now I'm working on a GIS project. I'm really slow at getting things done with Clojure but I can tell I'm getting faster.

I've also been enjoying lunchtime and evening walks. Something about going on walks seems to generate many project ideas for me. As a result, my list of projects to work on has been growing way faster than my ability to actually complete those projects.

</comment><comment><USER359> I'm working on a platform to generate simple CRUD APIs from JSON schemas: [https://stackprint.io](https://stackprint.io)

I noticed that while working on past side projects I spent a lot of time writing simple CRUD APIs, permission checks, client code to connect and model classes which (at least for me) is usually not the most fun part when working on new app idea ;) So I started creating a concept to automate most of that for future projects and developed a simple web platform around it.

During the quarantine I've been mostly working on a set of permission rules to control access to API resources. I also started on generating client code which at least works for Angular at this point. I'm very hopeful that I can stay productive and get it to work for React/VueJS and iOS/Android as well soon :)

I'm in my 30's and have always struggled with how flexible I am. Since lockdown I've spent just about every evening mobilizing anything that feels tight or uncomfortable has been a game changer.

I'm finding that I feel physically pretty great, less tight, aches/pains have faded away though there are still a few old injuries I'm working through.

Lockdown has been hugely helpful in maintaining the habit: kids go down in the evening, take the dog for a walk and stretch until you go to sleep has been a great way to unwind.

If you're looking to get started, I initially followed this guy's[0] youtube channel for a month, then started doing what felt right for me.

</comment><comment><USER366> I'm trying to get myself to wake up at 06:00 AM to go for an early 20 minute morning run. As an insomniac this has proven to be really difficult. But I really like running, even when I'm out of shape, as it has been a part since I was a kid.

I think I'm inching towards a stable rhythm though, but time will tell. I always need 2 months of a stable rhythm to be fully sure that I got a rhythm locked in.

Here is what I figured out so far:

\- Magnesium before sleeping

\- Vitamin D when I wake up, especially now since I'm sitting inside all the time.

\- Obviously basic sleep hygiene that all the popular blog posts write about (fun fact: I use Iris instead of Flux, it dims the screen even more).

\- Melatonin when I can already tell I won't be able to sleep anytime soon. I used to try to fall asleep on my own strength for way too long. Things I've tried: meditation (my username is derived from it), progressive muscle relaxation, not thinking about anything (I am quite good at this), visualizations of being in familiar places, exercise and going to the doctor. It all doesn't work. What does work: melatonin. Only since recently I've been a bit more aggressive with it (after 25+ years of sleep issues).

This leaves me with one issue: sometimes I wake up after 4 hours of sleep. My usual way of dealing with this is being awake for another 4 hours, so I can sleep my second quartet of hours. The problem: I wake up around 11:00 AM when I go to bed around 11:00 PM.

So what I'm trying now, since my lifestyle supports it, is waking up between 04:00 AM and 06:00 AM so that I have enough leeway to sleep a bit more. I'm starting a job soon and I have to be 09:00 AM in the office. This is my makeshift solution.

I hope it works.

<comment><USER367> I think this is what people did some centuries ago: Wake up in the middle of the night and do some stuff, then go back to sleep for a couple of hours. See [1].

I also have issues sleeping. When I sleep at my parents house, I sleep excellently. I did sleep there for a week a couple of months ago and I never felt so good. The downside is that my girlfriend gets upset when I sleep there for a week (and my parents think I'm in a fight with my girlfriend).

Things that might explain why I sleep so much better at my parents house are:

      - It's darker

      - It's less noisy

      - There's a better bed

      - There's no-one sleeping next to me in the same bed

      - Maybe I feel safer if I sleep on the second floor of a big house instead of right next to a street?

[1] [https://en.wikipedia.org/wiki/Biphasic_and_polyphasic_sleep#...](https://en.wikipedia.org/wiki/Biphasic_and_polyphasic_sleep#Interrupted_sleep)

<comment><USER366> Ah, yea. Varying sleeping locations, I've done that a lot, unintentionally. I've slept in humble homes to mansions to far out locations (my own place being a humble home). My best sleeping moments are when I go camping and rise and fall with the sun. That's the only time when I am capable of sleeping normal, waking up and falling asleep with the sun, no clock needed.

Here are my experiences to what you said.

It's darker: I use a sleeping mask.

It's less noisy: I used earplugs but I have tinnitus and it acts up when I do that. Currently though, it's not noisy because of Covid. Maybe I should have a noise cancelling / ambient white noise system. The normal tinnitus levels don't bother me, airplanes flying do.

Better bed: turns out, I love a mattress on the ground the most.

Sleeping next to people: that's funny, I sleep better sleeping next to someone! Well, we all differ.

Regarding safety: that's how I feel when I sleep next to someone. Not that I feel unsafe sleeping alone, not at all. I simply feel safer.

</comment><comment><USER369> I finally got fed up with Discord and I'm building a competing product. Not sure if it's gonna get anywhere but I'll be damned if I don't try.

<comment><USER370> What vexed you about discord so much that you decided to roll your own? Or was it just a general accumulation of petty abuse?

<comment><USER369> Discord is where my programming career started. My very first (serious) project was a Discord bot back in 2016, so I attribute pretty much everything I have to the platform. Obviously that made me care a lot for it, which means when it became worse with every update it always stung a bit. Off the top of my head though, here are the things I find baffling about Discord:

1\. You can't resize the channel list, and when resizing it's prioritized higher than the main chat window. This means that after a certain threshold of width the application is unusable.

2\. The developer experience is very lackluster. On Slack you can integrate your application to the point where it almost feels like it's a platform feature (you can even define slash commands with parameters and tooltips). On Discord the best you get is reactions on messages.

For more on this, recently I had to verify the bot I mentioned in the beginning of this comment, as per October 2020 all bots in more than 70 servers will need to be verified. I went against my better judgement and sent them a picture of my documents, and after the lengthy process I tried to use the application transfer feature and was denied specifically because it was verified. Support basically flipped me off and directed me to their feedback forum no one reads.

3\. No threads.

4\. Pretty much no control for voice comms. In video game contexts it's useful for the leader to be able to speak uninterrupted (muting everyone else in the call) at the press of a button. TeamSpeak has had this for 18 years.

5\. The permissions system is bonkers. Some actions are either nonexistant or hidden under items that make no sense. For example, what do you think the "Embed Links" permissions does? It allows/forbids you to send links, right? Wrong. You can send links, but it supresses the embed. If you need to supress links you need to use a bot.

6\. Keyboard navigation is broken. If you're on #channel2 of server 1 and want to go to #general, it makes sense to press Ctrl+K, type #general and press enter. You can do that, but it will throw you to a channel named #general in a random server you're in.

7\. Lazy loading of members sometimes means it's literally impossible to ping someone, even when they show on the autocompletion.

8\. Sometimes you click a channel and it'll be scrolled way far up. You then respond to a message, it gets scrolled down and you realize you're responding to what someone said 3 days ago.

I've no idea if fixing these is enough to bring users in, but this project is important because it'll either succeed or I'll get some appreciation for Discord again. I can't justify using it anymore after 4 years of broken update after broken update.

<comment><USER210> Very interesting! I've been looking for a self-hosted analytics tool to replace the Google. I'm going to take a closer look.

Btw, I don't think you need to _start_ a broader self-hosted movement; it's been building for a while. See [https://github.com/awesome-selfhosted/awesome- selfhosted](https://github.com/awesome-selfhosted/awesome-selfhosted) for example. Keep up the good work! You're not alone.

<comment><USER371> Thank you! I do know abnout that list (userTrack is already listed in the non- free section).

The problem with self-hosting now is that it's usually only for techincal people who know how to setup and maintain servers. I am trying to make so that you can setup, use and maintain my platform with a few clicks, without any technical knowledge. Currently I started doing that by using the cloud-init script for DigitalOcean, so you can go on DO, create a new droplet (with a few clicks), choose LAMP stack and add my cloud-init script which would automatically download and install userTrack. I think this could be optimized even better, in the future I "dream" of a world, where you chose your software (eg. self-hosted Facebook-like platform) and with one click you have your own server running it. I think the DO marketplace is a good start, but they should allow an easy way for developers to sell through their marketplace. I know docker somewhat solves parts of this problem, but for the non-techincal person, with the majority of the software you still need to do some configuration, SSH into some server or setup DNS records.

And with userTrack I feel like I can make a difference, as it's not only self- hosted but I do plan to make it the best analytics tool for landing pages or small websites. By having something that is better, you can make people think about the advantanges of self-hosting, people which would have never thought about that before.

<comment><USER210> I love the direction you're tracking here (pun not intended). The feature list is impressive, too. userTrack is now on the front of my list of options.

I've been working on a self-hosted social media scheduling tool (buffer/meetedgar-alike). So far it's just for my own use, but you've given me hope that there's a non-SaaS path to market. Thanks.

<comment><USER371> Thank you for your kind words. I am currently adding A/B testing functionality to userTrack.

Everyone pressures me to change the model into a service, but I think that by sticking to the product way I can understand what the biggest pain points are for users and the current state of the internet when setting up your own services/products instead of renting them. Also, I plan to open-source it at some point after I can earn enough to sustain myself.

So I had the thought of making a chatbot that is hooked up to their inventory database that can tell you where particular items are located. I'm just building the first prototype entirely in AWS, both to learn AWS and to make it easier on myself.

I figure that shoppers will use it because talking to a chatbot feels safer than asking someone in real life, and businesses will want it because it gets people out the door faster so the lines to get in are shorter.

<comment><USER400> An impressive amount of features going on there. The price is per month or annual?

Yet Another Focus Music generator to solve many of my problems using other services throughout the years.

What works best for me to focus is a combination of many services that exists on the market, so at the end I had to tune into many web apps on my browser which hogged my memory and I had to pay for many subscriptions making it a really expensive solution.

So I created this service, is still a work in progress, but I have been running to polish everything during this quarantine, right now I feel it is at a 90%.

(2) minishell. This is a simple shell with only 2 commands: either you (i) hit enter to view 10 files of a folder at a time, or you (ii) enter a filename and view nbytes. I built this because a co-worker wanted to view a folder with 20+GB of files but couldn't do it with an `ls`. With this, I hope that we can casually explore a folder without having to print everything. [https://github.com/remykarem/minishell](https://github.com/remykarem/minishell).

One important aspect is that the system is completely message driven. An actor can become anything by sending it a message. Yes, there is a security aspect to that :) It should also be compositional, in that the behaviors of it's essences compose.

\- [1]: I took a Coin Pusher arcade game and put together some electronics and software to make it playable through a Twitch stream. I thought it'd be fun to make and an interesting idea (especially with people being stuck at home), but it hasn't really gained much traction. It's currently a functional "MVP", but I haven't gotten any players so I can't figure out how to iterate and improve it. I built it using NodeJS, C++, a Raspberry Pi, an Arduino, a 3D printer, and an assortment of electronic components.

\- [2]: Rebuilt my personal website. I've been hoping to write more (mostly for my own sake). One of the things that was mentally impeding me from writing was being afraid of being incorrect. I like to learn, but I think I'm a slow learner and don't always get things right the first time around. However, I tend to usually figure it out. I think writing could help me through that process (and potentially other people that are learning as well), so I think it'll be easier if I approach my writing with that perspective. I built it using GatsbyJS and its hosted with Netlify.

</comment><comment><USER442> Trying to learn frontend so I can make myself a better to-do list/calendar app. I'm a robotics engineer so I have no idea what I'm doing, but it's fun. Due to executive dysfunction, I tend not to have a very good idea of how long it'll take me to finish anything longer than about a day's work (so I assume it "won't take that long", which fuels dangerous amounts of procrastination), so my concept was that each task gets broken down into subtasks that are small enough that I can estimate time for them. These time estimates then get propagated to the root task, and leaf-level tasks can be dragged and dropped into today's calendar (with other events pulled in from Google Calendar so I don't accidentally double-book myself). On the task itself I'll be able to record how much time (in pomodoros) it actually took to complete; in addition to tracking how I actually spent my time, hopefully this will help calibrate my future time estimates.

I also finished knitting a sweater -- my second overall, and first time not working from a pattern.

</comment></comment></comment><comment><USER444> I've been working on a small project called [https://CodeSnippetSearch.net](https://CodeSnippetSearch.net). It allows you to search through code snippets using natural language. Currently, Python, Java, Go, Php, Javascript, and Ruby programming languages are supported. I think it's especially useful for new programmers because it allows you to search through code in a "Google-like" fashion. It also allows you to find similar code snippets to the ones found in search results. This enables you to explore different possible solutions.

As with any cool project nowadays, CodeSnippetSearch is powered by neural networks (six in fact - one for each programming language). The project is open-sourced and you can read about the implementation details here: [https://github.com/novoselrok/codesnippetsearch](https://github.com/novoselrok/codesnippetsearch) This project started as a reimplementation of the models in the CodeSearchNet challenge by GitHub ([https://github.com/github/CodeSearchNet/](https://github.com/github/CodeSearchNet/)). I have reused their data and reimplemented the neural bag-of-words model in Keras. I didn't expect any improvements with my reimplementation, but I did manage to beat the baseline models by a little bit.

The search is still a bit of a hit-and-miss and I'm continually trying to improve it. If the match rating for the top result is below 50% it will most likely be irrelevant.

</comment><comment><USER445> I shipped an MVP of an instant messaging app that re-imagines the dynamics of chat. Your conversation is no longer limited to the vertical direction. It can expand in the horizontal direction to separate different but simultaneous topics!

[https://xpanxn.com](https://xpanxn.com)

I also did a couple of Show HN posts for it. Didn't get much traction with either, but it's ok because I think my next steps are to revise the landing page and get a more proper UI.

Feedback is very welcome!

<comment><USER446> > Feedback is very welcome!

I don't get it. Are you threading but just making threads side by side? The demo isn't making much sense because logically they could be all vertical.

And if you're just placing threads to the side, doesn't this require the main thread to be squeezed? I can't imagine this would look good on a phone except in landscape. But I haven't used landscape since I had a physical keyboard. Everything you have tells me this is what you're doing: a style change.

I think the demo needs a more clear example. What does it look like? The demo should make it abundantly clear what's happening and what your product solves. That's your 1 minute to get me hooked and read more. To get me to try it. New styles, even if more efficient, have more friction, because it is new and things aren't where you expect. Your demo needs to show that it is worth the friction.

<comment><USER445> Thanks for the feedback -- definitely agree on the demo! Based on some feedback from one of the Show HNs, I'm planning to make some fake little chat bot, so users have something to interact with (albeit in a very scripted/formulaic way) instead of sending a link to a friend. The chat bot will replace the static demo entirely.

It's definitely a style change first and foremost. I got sick of this pattern: friend sends message1, message2, message3; I respond reply1, reply2, reply3. And then they probably reply to some (if not all) of my replies. Usually it's pretty clear which message corresponds to which topic, but it's always messy. With XpanXn, it's explicit and visually obvious.

Each topic column is a fixed width. You can pan around the chat canvas and zoom in/out exactly as you'd expect! In fact, another motivator was knowing that a lot of people like really small font sizes on their phones. This way, you tailor font size just by zooming in/out. There's definitely some opportunity to improve that, but for now, I think the ability to pan tends to most of that concern.

It's a video editor with some really cool effects/transitions. In quarantine, I've been re-vamping the UI to make incredibly easy to create videos.

I hope to have another version in about 1 week where creating videos will feel quite seamless ;)

(Adding media into your video project has been hard - which is what I'm fixing right now.)

<comment><USER452> Maybe it's because I'm on mobile but I'm not seeing any images of the actual application. Personally when I work with an editor, me deciding to download it is heavily based on what it looks like. If I have to download it to see... I won't.

<comment><USER451> I completely understand. I'm in the process of rebuilding the UI - so I did not want to post "stale" screenshots. I really hope to have the new version of the app ready in less than a week, and then take a few screenshots and post them ;)

Having said that, in the near future (3-4 months), I will redesign the site. Already hired a team. It's really interesting how things your idea of what should be on the website changes as things shape up. So, it will be a redesign from the ground up - but for that, I need to have a few more features ready - and that will take tiiiiime :)

EDIT: I should have mentioned: this is Windows10 only for now. I may port it to other platforms assuming all goes well.

I think it is important to research what type of chicken is best suited for you. Ours are Jersey Giants, a so-called dual use breed. We keep them for eggs and meat, i'm used to the butchering part.

We let them roam freely for the most part of the day so they can hunt for bugs and snails. So far they don't mess up the garden too much...

Video trailer: [https://www.youtube.com/watch?v=Yqe0hS7AvOE](https://www.youtube.com/watch?v=Yqe0hS7AvOE)

Wasn't paying too close of attention to Monogame for the longest time, so the XNA code stayed dormant for years, but then I finally sat down to see how hard it was to port it to Monogame and I had it running in 24 hours. So I decided to sit down and rework and clean up the UI, upscale all the graphics (requiring me to remake them in Illustrator, since I originally made them in 720p in Photoshop), adding support for up to 6 players, support for localization to more languages, adding in-game achievements, adding new game modes (still trying to get a single player mode that feels good), support for larger maps, and recently trying to get socket programming working so I can add IP-based online multiplayer (maybe eventually with a server for a later release, we'll see).

Also debating switching the graphics to 3D, but that may be too much, and I'm not so confident I can rewrite shader code for each platform. I had trouble as it is getting a line effect I had in XNA working in Monogame on Windows.

Planning to release it on Windows and Mac first, and then expand out from there. Probably mobile (I released it once on iPhone but it was a port to Objective-C and that code is now ancient), then hopefully get it on the Nintendo Switch before the next console generation, then probably Playstation and Xbox.

</comment><comment><USER467> I'm making high power LED-based home lighting. I was inspired by this post: [https://news.ycombinator.com/item?id=21660718](https://news.ycombinator.com/item?id=21660718)

Basically our hourses are 1-3 orders of magnitude dimmer than the outside; this is not good. Ben Kuhn's approach was to buy a big 30k lumen LED bulb for $100. I am doing a more DIY approach with a number of small LED COBs. Each finished module will output 13.5k lumens for a bit less than $100 (so multiple will be needed per room), but it comes with a number of benefits:

\- The light is extremely high quality, almost the exact same as sunlight. Fluorescent bulbs and normal LEDs do not give off the full spectrum of visible light we get from the sun and incandescent bulbs. In fact I tried growing some plants indoors a while ago, and even though they were seemingly well-lit they ended up dying due to a lack of light.

\- The light can be dimmed to warm. Each module has four LED COBs. Three are bright white and put out 13.5k total lumens. The other one is a warmer white which should be useful at night - like IRL flux/redshift. And these can all be dimmed smoothly from 100% to 1% brightness.

\- The modules are controlled with an ESP8266, so they have WiFi. Aside from controlling them via a phone/computer, I am going to set up a Raspberry Pi running some timed scripts to automatically adjust them. For example they can all turn on in the morning as a natural wake up alarm (I have a separate alarm clock project I'm working on to give this a normal physical alarm clock interface). And I'm going to investigate using PIR sensors to make them automatically respond to human presence.

In the end this method is a bit more expensive than just buying high power bulbs (and more expensive than buying normal bulbs, but you would need like 70 of them in a room to match the total light output), but it has a number of seemingly useful advantages. Right now I'm working on the second (and hopefully final) prototype; the first was electrically OK but had thermal issues (LEDs still get very hot!).

It's an interesting break from normal software engineering. There's a huge emphasis on getting it right, and on getting it right the first time. Since there are a couple of amps of power running through the system, it needs to be well designed and safe from the very beginning. And $6 shipping every time you order from DigiKey punishes iteration heavily, since if you're making small iterations then your shipping will be much more expensive than the parts. I spent probably around 60 hours researching before making the first order. After finding out that the thermal solution was inadequate I spent a bunch of time theoretically fixing that and finishing up every single loose end (up to well over 100 hours total now). So now my second order will very likely result in a 100% complete, functional, and safe (I think!) product.

The only thing left is to design a lamp-style enclosure. The module is small enough to replace a lightbulb in an overhead socket, but the wiring would need to be changed slightly and working through a small hole in the ceiling is not really practical.

<comment><USER468> Brilliant! I've been wanting to do something like this because of how disappointing the commercial options are. Any chance you could share your design details? Even something as simple as a GitHub repo with a Readme and any design files would be amazing!

<comment><USER467> Just put up a quick post: [https://thepwner224.wordpress.com/2020/05/29/led- status/](https://thepwner224.wordpress.com/2020/05/29/led-status/). A bit unorganized and not really edited; I haven't slept in a long time and just wanted to fill my notebook and also write this down before I forgot any details.

My first design was supposed to be around $70 and make 8k lumens, but was useless because I couldn't get away with the cheap thermal management I thought I could get away with. My second prototype which I just did was $105 and was supposed to make 13.5k lumens, but even after much planning it seems the thermal performance is inadequate. The third one will be $145 and will make 18k lumens, and I believe it will actually be able to work at max power without overheating. Luckily the lumen output is increasing too along with these price increases so they're not really price increases.

But I have to say, it's totally worth it. While it's not stable at 100%, I did run it at that for a bit and my initial reaction was 'this is a second sun.' In my workspace which went from 300 to 1500 lux it really made a difference in perception. I spent most of the time with sunglasses and still being blinded while trying to take temperature measurements, but at the end I stopped and just turned it on and looked around, and everything looked _lit_ in a way it just hadn't before.

I'm working on a console-based RSS client in Haskell. The original plan was to implement the basic functionality of Newsboat (which currently is being rewritten from C++ to Rust).

It's still raw, but I already started using it as my primary RSS client. Right now it can fetch feeds, display them in a nice menu, maintain read status, open urls in a browser. The next features I'm going to add are support for configuration files (everything's hardcoded now) and tags + filtering.

\--

Newsboat had a few problems inherent to C++ (like occasional segfaults) and the TUI library it used. Knowing about these, I started googling for alternatives written in a higher-level language. And spotted the announcement [1] of the Newsboat author, saying that he's going to rewrite Newsboat in Rust. When I read that, the rewrite was already going on for months with still no end in sight. I thought, "Heck! I can implement this in Haskell in a few days!" By now I spent about a week of full-time work on the project (spread over months), and got a bare working prototype.

My estimate was too optimistic, of course, I didn't foresee all the difficulties I encountered later and all the things I had to learn. But still, I think if I spend one more week on this, I can get a fully-featured and polished RSS client — Haskell makes programming a lot cheaper.

<comment><USER98> Would it be possible to extract full text from articles and view it all in the terminal?

<comment><USER469> RSS feeds often contain the article text in HTML, and parsing webpages shouldn't be necessary. Kalina, like Newsboat, does support viewing these in terminal—I use Pandoc library to convert HTML to text, links and images are not preserved.

I don't know if fetching webpages and rendering them in terminal is a good idea. You can always use a terminal-based browser like w3m to open them. And I'm afraid most of such pages will be cluttered with animated popups and sidebars, filtering which will require some heuristics. Don't know it's worth it. But this is still something to look into in the future—at the moment there are more urgent things to do in Kalina.

</comment><comment><USER493> Studying: differential geometry, poetic edda.

Doing: lifting myself to hell and back and jump rope.

Building: Making maze generators in minetest (before moving them to minecraft)

And trying to figure out if I can find a function that takes two finite consecutive sequences with length N and M of natural numbers, which start by 1 (E.g [1,2,3], but not [1,2,4,5]) and give back a sequence which contain all the numbers starting from 1 up to the NxM, but not necessarily sorted without using the size of the sequences. So I want to number the cross product of the two sequences.

This crap is related to some programming problem I hit.

       t = {1,2,3...} -- <- can be lenght
       s = {1,2,3,4...} <- can be any length
       xs = {}

       for i,h in ipairs(t) do
           for j,k in ipairs(s) do
               q = f(i,j) -- <- I want to know if f is possible
      to write
               xs[q] = h * k
           end
       end

Well the answer is I think no, but I found some functions that work up to a certain number or that work within certain bounds, so how far we can stretch that? And of course it works for the whole set of natural numbers.

<comment><USER494> Pretty sure the answer is no as a math problem where f is pure. If f returns the same answer each time, the square ending at N,N contains [1, N * N]. Then the rectangle ending at N,N+1 must contain (N * N, N * (N+1)] in the nonoverlapping strip. Ditto for N+1,N. But then for N+1,N+1 all other locations must contain low numbers and there's only a single corner cell left which can contain the rest of the missing numbers between (N(N+1), (N+1)(N+1)]. Unless I made a mistake I don't think any function would work here for N > 1\. What were the examples you found?

OTOH as a programming problem you can just cheat and store state somewhere to count the row width. This satisfies your interface requirements (python):

        lastJ = None
        def f(i, j):
            global lastJ
            if i != 0:
                return i * (lastJ + 1) + j
            else:
                lastJ = j
                return j

        N = 3
        M = 5
        seen = set()
        for i in range(N):
            for j in range(M):
                q = f(i, j)
                seen.add(q)
        assert sorted(seen) == list(range(N * M))

It means you need to find a function that walks the numbers in a nice way, like seen here: [http://szudzik.com/ElegantPairing.pdf](http://szudzik.com/ElegantPairing.pdf)

I think it isn't possible to find a function that works for arbitrary sequences. I know there is a function that works if the sets have the same size (n is size), it is trivial why those work. They have the form n^0 _a + n^1_ b, where a,b are in [1..n]:

          f :: Integer -> (Integer,Integer) -> Integer
          f n (i,j) = i + (j - 1)*n
          -- For example:
          f 3 <$> ((,) <$> [1..3] <*> [1..3])
          [1,4,7,2,5,8,3,6,9]

Now I want to find functions like (n,m is size, n /= m):

          f n m (i,j) = ..

And functions where n maybe chosen but m is between certain bounds. I have found a couple of those by mutilating pairing functions.

I know I can use a counter, but I don't like cheating :p

I need to draw your reasoning on a paper to see it or take some time for it. Little bit busy, working from home, having the kids and stuff :p

<comment><USER493> Made a small error:

              f n (i,j) = (i - 1)*n + j

These also work for when i > n as long as j is between 1 and n.

After being able to print I tried drawing. Both blender and fusion 360. Blender for organic objects and fusion 360 for practical engineering objects.

It's a really fantastic hobby and you'll be able to produce a lot of physical objects instead of only writing software.

I've now integrated it with a couple of systems which allow me to get OHLC data as well as Regulatory News Service articles. And, in order to improve the quality of the forecasts, I'll soon begin integrating it with other news sources.

I've added it to (Collective 2)[[https://collective2.com/details/128426551](https://collective2.com/details/128426551)] and its currently making a loss as a strategy. This is good news because it's allowed me to identify why that loss might be occurring and where I could improve my strategy (I've found quite a few improvements in the last few weeks). The most recent improvements are active on a non-visible strategy on collective2

This forecaster could be applied to any global exchange. And I'm looking forward to the day where I can trade with it myself, sell the signals as a service, or sell it for a tidy sum.

<comment><USER505> Have a two year old who is wants constant attention. Typical day is I take the morning shift. Wife does the afternoon shift and I again do the evening shift. Once the toddler goes to bed at 8 pm, we both work (typically past midnight)

What makes this very challenging is that a) Kid wants attention continually so there is no point in trying to do any work while it is my turn.

b) We live in an apartment complex and folks who live downstairs have called cops on our kid multiple times for running around. This despite the fact that he never does during "queit hours (sleeps from 8 pm to 7 am)" and these noises are protected by SF tenant laws. Couple of weeks back a SF police officer knocked on our door and tried to arbitrate. Internally, I wanted to slam the door in the cop's face though I was respectful.

c) Because of (b) kid knows that we are very sensitive about him running around. So anytime he feels he is not getting attention, he will run or stomp on the floor.

<comment><USER506> > cops on our kid multiple times

obviously 'talking' wouldn't have worked here.

If they are just ignoring the cops, why would they listen to neighbor.

<comment><USER504> I've had downstairs neighbors like this: we were quiet, responsive and tried our best not to make a racket. My wife and I were out of the house most of the day, but they kept on calling the cops on us.

I've placed a desk, installed Ubuntu on an old laptop, placed a screen, put down a mat and some dumbells and just watch cardio and resistance workouts on YouTube. It's a great way to keep myself in shape and to break the day because I work from home all days.

<comment><USER509> I'm doing something similar. In normal times, I go to the gym every day or two and work out for an hour and a quarter. Since I'm now home all day, I've been doing bodyweight and dumbbell workouts next to my desk for fifteen or twenty minutes several times a day. They break up the monotony and refresh my mind for the next round of work. I also fit in extra exercise during Zoom meetings that I only need to listen to.

The result has been that I am staying in shape despite being indoors all day. The staggered workouts may be more effective at building muscle than my usual gym sessions, too.

The greatest benefit of the exercise, though, is the mood elevation.

Now that I have the time, the code is far better organized and the higher level structure pretty clean in that I can copy a module, customize it a bit and now a different feature set can be generated. Churning out different ensembles should be fairly easy as well. And of course I'm throwing dask, mlflow and dvc into the mix...

I don't really need to do this (ought to be looking for a job...) <and I'd rather write code than pay to use someone else's SaaS>

but now that I have quite a number of different review datasets to play with, a framework that lets me spin up 10+ processes across the 5 machines I have at my disposal will make short work of most the sets. I will need the uni's HPC cluster to deal with the Amazon dataset, though. Using dask will surely help with that.

Then it's writing yet another paper... Not being allowed to go outside is rather motivating.

</comment><comment><USER512> A movie recommender (item-item) that recommends movies similar to a proposed movie. The similarity is based on tags, specifically the tag genome created by GroupLens.

This is mostly because I have a personal need for this and I would like alternatives to existing movie recommendation services, but I may make it available online if time permits.

A second step would be to introduce an example critiquing aspect, allowing for interactions like "show me movies similar to 'Crimson Peak' but with less horror".

All of this is based on the MovieLens 25M dataset and an accompanying article ([http://files.grouplens.org/papers/tag_genome.pdf](http://files.grouplens.org/papers/tag_genome.pdf)) describing a recommender called 'Movie Tuner' that is no longer available.

It will be fun to tune the recommendations based on my own preferences. For example I don't need an algorithm to suggest movies that have the same actor/director.

Initial results are encouraging.

But exactly the opposite happened. After a sharp collapse in visitor numbers in the first days of the crisis, they shot up again. More than I knew from before. That was astonishing but in retrospect logical: because here in Germany there was no real curfew, only a ban on contact with other people. So people probably thought: before I lounge around at home, I'll do something for my health and fitness. You can also tell from other comments here that fitness projects have worked. That motivated me to do my project even more intensively, because I realized that it is important to people.

[https://github.com/zero-one-group/geni](https://github.com/zero-one- group/geni)

I used to work at a tech giant, where the data team relies a lot on native Spark in Scala. I've always found the combination quite pleasant to work with. However, I did miss Python's faster startup time, dynamism and REPL, especially when doing data cleaning and exploration with no intention of putting it in production.

Now that I'm doing my own thing at a much smaller scale, I naturally gravitated towards Python's data stack, namely NumPy, Pandas, Sklearn and Dask. However, I found myself missing Spark's consistent SQL API and performance!

So yea, I've been wanting to use more Clojure for work and set up a Clojure shop. During the quarantine, I find myself having more time to do focused work. I thought this would be a good opportunity to convert some of the data wrangling stuff to Clojure!

I only had a few courses in college concerning analog circuits, but if you understand the principles, it's easy to learn from the schematics available on the internet.

So far I've been exploring the use of MOSFETs - I found that the 2N7000 transistor is as cheap and abundant as BJTs, so I'm using it.

This type of transistor is less predictable and has a more complex working principle than a BJT, but with that come additional possibilities.

My last non-idiomatic-but-working design is a MOSFET-based A-class buffer that maintains an optimal operating point using a BJT differential amplifier as a comparator for the feedback loop, maintaining the DC output before the coupling capacitor at exactly half the supply voltage.

It's not linear, but that's the idea - if you plugged in a guitar to it the difference wouldn't be really noticeable, but doing the same with a bass should give a "sweeter", enriched with low harmonics tone.

I got a very cheap one off Amazon, and only through dint of my prior musical experience (bass 10 yr ago, violin 30 yr ago), was able to put it into a decently playable shape.

[https://www.lockdownlinks.co.uk](https://www.lockdownlinks.co.uk)

It's a simple site that features some links you might find handy during the lockdown. I've tried to put together a list that doesn't feature obvious choices.

I used Vue w/ Gridsome, it's hosted on GitHub with Netlify handling deployments. Honestly, it's been a dream to develop on. Gridsome is very user friendly, and I learned about GraphQL while making it (something I'd been meaning to learn about for a while) Using Netlify and having 'git push' automatically kicking off a build and a deploy without me having to do anything else has been so convenient. I'm definitely going to use a similar stack in the future.

It's an open source, simple (all metrics on one page), lightweight (1.4 KB), no cookies (no need for cookie banner) and no private data collected (no need for GDPR consent) alternative to Google Analytics.

The code is on GitHub [https://github.com/plausible- insights/plausible/](https://github.com/plausible-insights/plausible/)

<comment><USER566> Congrats. Interesting project, looks great.

Could you comment on how you achieve GDPR compliance without the need of me getting a user consent from my visitors? I was always assuming that using a hosted solution like Plausible for analytics will at least result in the visitor IP address leaking to the service provider ... and for this I'd need consent if including your script?

<comment><USER565> Thank you!

Here's how we've done it. There's no legal precedent but we believe this makes us compliant:

To enhance the visitor privacy, we don't actually store the raw visitor IP address in our database or logs. We run it through a one-way hash function to scramble the raw IP addresses and make them impossible to recover.

To further enhance privacy, we add the website domain to the IP hash.

We also add the User-Agent string to the hash.

We've shared more details on this here [https://plausible.io/data- policy](https://plausible.io/data-policy)

<comment><USER566> Thanks. Had a lot on your site before posting, but didn't find that details. Perhaps you should add a link/hint on the frontpage regarding how you address GDPR compliance. (I'm not a lawyer, so I'm not qualified to judge on the solution.)

<comment><USER565> Thanks for the feedback. We link to it from the top menu under "Why Plausible" as "GDPR / CCPA Compliant" but perhaps there could be a better placement for it. Thanks again!

Rather than track people surreptitiously it's completely public and voluntary. It allows for feedback to let people "+1" items on several dimensions (basically a big bag of emotional adjectives) and I want to rank the "truthiness" of facts, from physical laws and math (at one end) to opinion and interpretation at the other, with a (metaphorical) low-pass filter for BS and crap.

All information on the network is public, there is no walled garden or silo. The idea is to think things out together, in public, avoiding repetition and noise.

I did get some extra time because one of the few things that were actually closed down was my Aikido dojo. But mostly I exploited the fact that friends in Italy and Belgium could not go out at all and... I started an online RPG campaign using Discord as a platform and Mini-six for the rules.

We are having a blast - I hope that the players will like enough to keep playing even after they get back to a more normal schedule in their life (me, as the GM, I have done some up-front investment in preparing lots of content and so I think I will be able to run it even when I go back to 3/week practice).

</comment><comment><USER571> I've been focusing on re-making my various Web party games into a more unified platform at [https://jklm.fun/](https://jklm.fun/)

The previous iterations were built years ago using CoffeeScript, Grunt/Gulp, Jade, Stylus, etc. This time around, I went for vanilla HTML/JS/CSS, no transpilation, no bundler, no build step at all (and no frameworks). It's been a joy. I'm using the TypeScript compiler in VS Code for sanity checking and might add some JSDoc to leverage the type checks even, but for now it's quite nice as is.

I've also enjoyed building up a Discord community for it all, got almost a thousand people in there now and it's a lot of fun interacting on a daily basis.

</comment><comment><USER572> A folding hardtail mountain bike with a mid-drive electric motor, a torque sensor, a geared rear hub, and a coaster brake. Maybe a belt too (I wish).

The e-bikes I've seen offer a small motorcycle in disguise, but what I want is a set of superman's legs, while not being a superman.

<comment><USER573> Which e-bikes have you been looking at? I've ridden the Trek Powerfly and the YT Decoy and they're both exactly like what you're looking for. They only add to your output and in proportion to it. I also have a Raleigh cruiser e-bike and it works the same way. I was under the impression that all but the cheapest class 1 bikes work the same. I have ridden a couple rear hub drive bikes like the Rad Rover and they have a more "on or off" feel. The motor starts as soon as you start pedalling at whatever power setting you have selected

<comment><USER572> Thanks for your comment! I have tried the Rad Bikes and I had the exact same feeling like you. No cadence assist for me.

I looked at all the bikes you have suggested, and sadly none fit the bill. I didn't think they would - I have studied the subject extensively.

1\. All popular mid-drive motors such as Bosch and Shimano are designed for European market, capped 250 watts, sometimes 350 watts. The max legal in the US is 750 watts, and I really want the max. I might even need the max when bike packing, or simply climbing up the hill where I live (it's pretty bad).

2\. All legal powerful motors are rear-hub or front-hub. They can't take advantage of the rear wheel gearing, so they can't climb the hills. Rad Bikes have it written in the instructions that one must not use max assist when climbing uphill.

3\. One can find non-street legal motors (how about 3000 watt) and they will climb rather well without gearing, but I want to stay within the law and conserve battery power. They are also heavy, and I might need to carry my bike on stairs.

4\. There is a handful of street-legal powerful mid-drive motors, but they are mostly use on custom builds (Bafang, Tonsheng, etc), and even then only some of them seem to support torque sensors.

Then there are other concerns: it's nearly impossible to find full-size _folding_ mountain bike, they are all 20" tire size. The $4k+ tag is about twice as much as I am planning to spend. Most of the bikes have rear shocks (stealing power - see "bike bobbing").

Generate a unique whiteboard and share with a friend to see it in action.

We were struggling to conduct software architecture interviews since going remote at my job because we no longer had a whiteboard, so I built InterviewBoard to fix this.

It's pretty sweltering here in San Diego, so I wanted to make frozen treats for my dog, but all the recipes online are mainly yogurt (which he hates) or peanut butter (which I use to feed him his flea pills, so he flees when he smells it now).

I started by putting some freeze-dried meat into a food processor until it became a dust, then I started adding some other ingredients for flavor/smell/consistency. I was really happy with the results, so I thought I'd try selling them! So far just a few sales, but I haven't done much marketing to this point.

<comment><USER187> What piano software was your favorite? And what device do you connect your piano to?

<comment><USER577> Simply Piano was pretty fun but the Android version is lacking in features. I connected a Roland FP-30 to my Samsung Note 10 using a OTG adapter and it works just fine. I also had some issues getting audio without using the phone speakers since there is no minijack and Bluetooth latency was unacceptable.

I tried Playground sessions and Flowkey only briefly but I liked the UI in Piano Marvel better. Also Piano Marvel doesn't require your credit card to get a free demo.

I ended up with Piano Marvel and a Windows laptop. What I like is that it's just sheet music. Very good for training rhythm and tempo. The UI is a clunky and buggy SPA, but it works. Biggest con is that the music is pretty bad. Simply Piano has licensed tons of popular music while Piano Marvel has mostly free and classical music.

<comment><USER136> Rocksmith pretty good and goes on sale on Steam regularly, if you end up finding that building something will take too much time.

<comment><USER598> I'm using Rocksmith and Yousician (the free version), but I think there's room to improve over what both of them provide for practice / exercises. For learning and performing songs they're definitely the best due to the sheer amount of content they have.

I'm very early in my learning journey so I'm not concerned that developing a prototype version I could use for myself will take too long (it could be that I'm underestimating the difficulty of the problem). I was already able to slap together most of the "glue" code in Unity in a couple hours, and given my signal processing background I have solid ideas for how to approach the difficult algorithmic parts.

<comment><USER136> Since you have a signal processing background... what would be super cool is if there was a tool that could analyze all the chords in a song file (e.g., mp3) and magically create a Rocksmith/Guitar Hero style "racetrack" for practicing. DLC can get expensive quite fast, and songs you want to play may not always be available without modding/hacks/cracks, etc.

<comment><USER598> I'll keep this in mind! It is a tremendously more difficult problem though due to all the other instruments (including voice), distortion, etc. in real music tracks compared to a clean guitar signal. This is when you would have to break out the neural networks. Machine learning happens to be my day job so it's not impossible! But for now I'm keeping my target scope small :)

Was a little new to npm as well, but got rolling after a while. Not done yet, still little issues with flow state, for example, if I have a dual range slider in react with clearly styled and labeled beg and ending sliders values, how do I drag one slider over the other and force swapping the two but continue the UI motion.

</comment><comment><USER607> I am working on a novel. It is the third novel/story I have started since 2016. I will probably abandon it before completion but I am practicing and improving my writing. Eventually I hope be able to write a complete novel. I haven't had anyone review the writing as I am still at the point where self diagnosis and correction is fairly obvious (I make a LOT of mistakes). There is plenty of good writing advice and exercises on the Internet; my writing problems are extremely typical for new writers.

Like my early software, I expect that my current novel will eventually collapse under the weight of inherent lousiness. I will then start again and do better.

Abstract: _This book is intended to be a tutorial that teaches the functioning and example uses of the Common Lisp condition system. It is aimed at beginning and intermediate Lisp programmers, as well as intermediate programmers of other programming languages. It is intended to supplement already existing material for studying Common Lisp as a language by providing detailed information about the Lisp condition system and its control flow mechanisms, as well as description of an example ANSI-conforming implementation of the condition system._

PhotoStructure will get your piles of digital files organized, but it can't guarantee that the disk won't crash, that you have a backup, or that the computer won't go kaput. A printed book on acid-free paper and archival inks can just sit on a shelf and be fine and readable by anyone 50 years later. No technology can say that.

Also: assume the images are irrelevant by default.

Try to write _something_ on the back of each photo explaining why it's relevant. At least write when it was taken. Bonus points for who is in it, and the event.

When my brother and I went through boxes of old photos without annotations of any kind, and not being able to ask who's in a photo, or when it was taken, or why it's important, meant most of the contents were irrelevant to us. Very sombering.

<comment><USER362> I believe there's an error in your cagr function: I didn't look at how it's used too closely, but whenever you see 365 in financial code it's usually an error. It would be more appropriate to use 252, the average number of trading days for US equity exchanges, instead of 365.

I have some questions regarding the article: How are you hedging? What instrument are you hedging with? Also, how much leverage are you taking on? If you're not selling out any original shares and shorting an equal amount of some other shares (see my first question), you're taking on 2x leverage. As such, you're not really comparing apples to apples.

Moreover, Puru Saxena is not really doing what your blog is describing. What he's doing (at least according to some Twitter posts I read), is holding a market neutral portfolio where the long side consists of specific stocks he likes and the short side an ETF to hedge the geography exposure. Because he's investing in high beta tech stocks, he can lower his beta and his geography exposure through shorting the appropriate ETF. This is a smart strategy, but is only going to work on high beta companies.

Anyways, in general, we do not want to look at returns when analyzing an investment strategy. Instead, we should look at the Sharpe ratio. While I don't have enough information to say whether your results are correct, honestly, they don't pass the smell test. I feel like the EMA window is overfit, your CAGR is being boosted by the use of 365 instead of 252, and I suspect that you are taking on leverage, which might be also boosting your returns.

Also looking at the code, it's needlessly complex because you're dealing with actual shares and such. A better method is to just deal with returns directly and represent your portfolio as a vector of weights, the sum of the absolute values should add up to zero with no leverage.

The type of hedging you describe in your example is equivalent to just selling the shares, but a little worse. You're paying interest on your shorts, so you're losing 2% annually from holding shares and shorting some other shares. There's literally no reason why you would want to hold both a long and short position on a stock.

I recommend you check out Quantopian ([https://www.quantopian.com/](https://www.quantopian.com/)). It makes your life _so_ much easier and they have all the data, plus great risk models and alpha factor generation tools.

Also as a fellow software engineer interested in finance, you might like my financial blog, [https://cryptm.org/](https://cryptm.org/).

<comment><USER659> Yeah, and nay.

365 makes sense talking interest. But so does 360. And then there's +1/+2. And more fancy stuff. It all depends on currency. So, 365 makes sense from a mentality of opportunity cost and accrual, given an ACT365 currency.

And I wouldn't go with 252 because of OTC.

I also would strongly advise against Sharpe ratios. From the title of the post - which I have my own problems with the post, but - "Why only buy when you can also sell?" really highlights why not to go with Sharpe, or Sortino, ratios: non-normal returns are the normal. Better with Omega, which is a concept already 20 years old but finance oddly sticks to the 80s.

<comment><USER362> The Omega ratio doesn't solve the problem of non-normal returns. In fact, it makes it worse: The Omega ratio requires a cumulative distribution function of the returns!

1 - Seamless fast search.

2 - Graphically conveying the sugar measure.

The first one is what I really worked on, to make it fast and intuitive. Still needs improvements. The second one is still a work in progress since I am no designer.

<comment><USER663> It is a good initiative but I am not convinced. This already exists so the need is not pressing. How did you think of monetizing?

<comment><USER662> No monetizing scheme so far. I think even if it ends up as a public service, it will be good enough.

I still don't know how to visually convey sugar. In a matter that is more dramatic. Working on some animations for now.

Over the years spent reading HN, I noticed that some comments with the best information ratio, were the ones based on data. I wanted a way to quickly find them, otherwise I would miss them.

Surprisingly, reading that feed has started to be part of my daily routine. But I am still toying with features I have in mind. Feedback would be appreciated !

It should enable yogis to find suitable online classes but also help out the studios to guide customers to their online offering. Lockdown is slowly lifted around here but there is still a limit on the number of people allowed in a yoga class.

I figured it could be a nice way for friends to reconnect and get their minds off the anxiety and tedium of lockdown. I want to use the Facebook Instant Games platform, but their documentation has been difficult so far.

Professionally, two different clients have postponed their projects until October, which is getting a bit worrisome. Some members of my team have been advised to propose summer projects that will help automate our engagements, because Q3 will be light, but then Q4 will be a deluge of chaos and demand.

We've made a few apps in the past that monetize with consumable purchases (specifically things like virtual currency, extra swipes for a dating app, etc.) and realized the backend we wrote each time for storing user inventory after making an in-app purchase was almost identical. PurchasePoint handles the details of Apple StoreKit and Google IAB transactions to track user inventory for you.

The end goal is to generally improve my ability to prototype PCBAs in my home lab, starting with a CAN gateway module that I've been designing. I'm hoping to be done with quarantine before I get to actually use the reflow oven.

<comment><USER678> Neat! Do you get paste stencils made as part of the PCBA manufacturing process? How many components a year were you hand soldering or reflowing before you decided to try and automate the process a bit more?

<comment><USER677> I've done stencils from OSH stencils before, but its not something I usually do. Typically I solder only a few hundred SMD components per year. The oven is less for reducing soldering time and more for increasing part selection; Too many parts come in leadless packages like QFNs that are painful to solder well by hand.

<comment><USER678> Got it. I have a project that I want to do based on a TI CC-1125 to connect 303 MHz devices in my home to a smart home system, but of course all the interesting parts these days come in QFNs. I was trying to decide whether I wanted to go through the trouble of reflowing it with hot air or if it was just worth the $100 for the booster pack development board. It's unfortunate that the economics of low-volume prototype manufacturing don't work out for the home designer.

It allows you to create a reminder for someone else, then provides a series of messages, starting with a heads up, the actual reminder and a follow up asking if the prompt was completed. The user can reply and the loop gets closed, you get a response saying the task you assigned was completed.

We've had some interest from developers in using the core api. So, we're using this time to convert the core platform into a api for developers.

</comment><comment><USER813> I'm working on gerrymandering. Both parties claim that the other party is better at it. My hypothesis is that some gerrymandered districts benefit the incumbent to the point of actually benefiting the opposing party in the adjacent districts. So, the incumbent has a safe seat, but the net is a loss for his own party.

I'd like to be able to demonstrate and quantify it.

</comment><comment><USER830> I've been working on a "newsbetting" site. Basically, you get a de-titled article and have to place a bet whether you think the source has a right leaning bias or left leaning bias. The idea is this betting market will force people to contend with their biases which will then reduce the proliferation of fake news. Theoretically

<comment><USER831> And where do you get the ground truths for the bias of the sites?

<comment><USER830> At the moment I'm using allsides.com[1]. There will always be some dispute about how biased a news organization is, but most people have the general understanding that, for example, Breitbart is more right than the HuffPo. At some point I'd like to add a voting feature, so you're basically trying to compete against the crowd

[1] [https://www.allsides.com/media-bias/media-bias- ratings](https://www.allsides.com/media-bias/media-bias-ratings)

<comment><USER832> So really you're betting on what "allsides.com" thinks, not if an article is _actually_ right or left leaning (since there is no objective measure of right/left leaning).

<comment><USER830> Somewhat. Allsides has a whole system[1] as to how they assign bias which is fairly robust, in my opinion. You're not betting on what the moderator at allsides think a source bias is, you're betting on what all of the patrons at allsides think the source bias is which is a little better.

But you are right in that no one can "objectively" measure partisanship since there is no such thing.

The real sticking point for me, apart from the lack of stock, is that I never call anyone using WhatsApp or Messenger. I'd ideally like compatibility with other platforms. I figured I'd start with Jitsi as its open-source, and go from there

I did briefly look at how I could get FaceTime working on something, but I think it involved jailbreaking an iPhone and getting access to the SSL certs.

I thought this is going to be useful especially when you don't want to go search and browse dozens of webpages on what to watch or listen to or do... and it's highly optimized, even though it can be slow because I don't use CDN (but blazingly fast in Europe).

You've also listed movies (not animated) which I didn't add, yet. Probably need a different category called "Movies" and the current one rename to "Animated Films". But I'm already working on other things (a different project), and suddenly don't have time to maintain this project (it's not dead, though!), because I'm bad at advertising and probably no one knows about this website's existence :') Thanks for recommending it, though! I'll figure it out

<comment><USER258> As a developer, I'm curious to know how 'Step 3' is supposed to work compared to other ways making recommendations.

One of the big problems I have with recommendations is recommending things I've already watched. Netflix used to be so good at the start, now my tastes are just pooled in with what everyone else is watching now.

<comment><USER933> So, when you join the app, you will go through onboarding flow where we try to understand your movie genre interests, as well as, you can opt-in to give suggestions in the future (this way you become part of community). So, once you submit a request, app will send those request to selected ppl from the community asking for a good suggestion. Once they suggest movie/TV show/series, you will be notified and will be able to pick those that you like/dislike. App will try to understand who are ppl from the community which suggestions you liked the most and in the future will connect you profiles similar to those people. That way you will have your unique path. The main reason for this is when we did PoC most of the participants stressed that they take suggestions from people they know and share similar taste. But again, we are in stage of releasing our MVP, so I'm sure there will be more things to learn :) Hey, why not subscribe for "Early access" and help us crack that part :)

<comment><USER936> This is awesome. It's a really nice layout. How do you find related cocktails? Database tagging, or some kind of a distance algorithm?

I made something similar a couple years ago: [https://github.com/gthole/drink- stash](https://github.com/gthole/drink-stash)

What is CocktailLove written in? I couldn't seem to dig up the source anywhere.

<comment><USER935> Thanks! I want to do a redesign actually but too many other things on the plate..

Right now related are just manual actually. I planned on creating some type of graph and computing some type of distance but not yet. Let me know if you have ideas :)

It's written in Python (Django) with Postgres and just vanilla JS on the frontend. Looks like yours too?

<comment><USER936> Yeah, mine is driven by Django Rest and an Angular app for the UI. I'm seriously considering moving to React, though. I just use Sqlite for the DB layer because it's easily performant enough.

I used Drink & Tell (and its sequel Drunk & Told) for the primary source of recipes, which I can't recommend more.

The "related recipes" thing is interesting. If I stick to doing it with a sql query, then I think an algorithm to pick out the base spirit, then filter on that and on whether it's shaken/stirred/scaffa, then sort by common ingredient count? Then again, an Elastic Search stack can do related objects out of the box, but I wouldn't want it to get that complex :)

<comment><USER935> I haven't tried standing yours up yet but will tomorrow! Do you have all the Drink and Tell/Told recipes as fixtures? Or just a few?

Your repo is nice and clean, definitely learning from that, and your model design.

Any reason you haven't deployed as a web app?

Oh and for related.. an issue is that sometimes related recipes are really quite different (e.g. an old fashioned riff with Gin and St Germain, or tequila/mezcal) so would be tough to automate..

<comment><USER936> It's deployed alright, I just don't publicize it since I only intend it for personal use.

None of the D&T recipes are fixtures, since they're technically copyright material. I set up classic cocktails as fixtures for people who want to spin up their own or play around with the repo.

Did you try standing it up locally?

Yeah the related cocktails thing is definitely an interesting problem.

I've had a persistent cough for over 6 months, and decided that with a respiratory-based pandemic going around, I ought to do what I can to get rid of it, or at least strengthen my lungs while I have the chance.

And after deciding to pair it with some calorie monitoring, I've gone down almost 5 kg since C-19 started!

<comment><USER970> Nice job!

I'm a cyclist myself, which is one reason I don't have a quarantine side project -- I've just stepped up my (indoor) training. I'm stronger now, measured by functional threshold power, than I was before COVID-19 killed all my group rides.

(Well, for certain values of "stronger" \-- I'm MUCH better at shorter intense efforts modeled on the trainer (say, < 90 minutes) but obviously I've lost some fitness for longer efforts (the week before we locked down here, I did an 80 miler with some racer friends).)

What are you using for calorie monitoring? I've found MyFitnessPal to be very useful, mostly b/c it has a huge library of food in it already. My wife used it to alone to lose about 30 pounds; just the act of watching calories in/calories out is super helpful.

<comment><USER1027> Great question! You're not being a debbie downer, that's a totally reasonable thing to ask.

Sure, lots of UI designers do. But it isn't a process that scales. If you're trying to define design requirements for a product that's very large or distributed (i.e. Netflix), manually drawing pictures of a UI is simply too slow.

Some designers have taken to writing CSS, and some even prefer it as their main design tool. I think that's awesome, but CSS exposes lots of implementation details that are only relevant to the web. I'm trying to create a declarative syntax that feels as easy as CSS, but exposes lots of functionality that would normally require javascript. And it will be abstracted from the platform, so this would serve not just web designers but also iOS/Android/TV/etc.

<comment><USER135> > I am too scared to give it real money

You should be. I hedged a bit recently with some options. Options can be low- volume, so the bid/ask spread alone can kill you. Read that bit again. If you're not accounting for the spread, you might get killed. They're also incredibly volatile right now. I've had days +/\- 30%. I'm not sure if someone like Robinhood goes lower, but a contract is for 100 shares, so the min bet is big.

<comment><USER1083> Yeh your right, It's programmed to not mess with anything where the bid ask is >3%. Otherwise yeah, it would get eaten alive. It uses a combination of unusual options flow and some basic technical analysis to make trades and has been doing well so far but... it is easy to lose a lot quickly if ya blow it.

</comment><comment><USER1094> Learning touch typing. I've never been 100% on typing without looking at the keyboard when going fast, and I think that learning to do so would boost my productivity.

<comment><USER1095> Another useful skill that I've found helps is getting good at reading from a source and typing it as you go. When someone's presenting, I can quickly type something they're showing. Usually quicker than interrupting, asking them to copy & paste and then waiting for them to get on track.

Another is if for some reason you get sent a printout, an image or something, transcribing whatever you need from it is super quick.

If it's too fast I don't internalize what it says, I just type, but it's nice.

A personal story, My grandma and my mom where both secretaries. I used to sat down on the typewriter at home for fun. As soon as I did and started typing you would hear, "back straight!, hands!, feet on the ground!"

When we finally got a computer, it died a bit. They couldn't hear the keyboard when I typed so I had some time to slouch before they walked in and saw me.

That's of course if I remembered to turn off/down the speakers when I booted the computer up.

<comment><USER1094> Ah, definitely. I'm in a work-from-home situation right now, and have been trying to type things during video calls (being careful to mute my audio and not show the typing on video, of course).

When the lockdown started, I noticed I had a two food-related problems: 1) I was used to stopping by the grocery store more or less every day on my way home from work so I had no habit of planning ahead for more than a few days at a time. 2) In order to fit a week+ worth of food in my apartment, I had to distribute it between a few nooks and crannies which made it difficult to track what items I had where.

To help transition to my new once-a-week shopping schedule, I used Trello at first but that quickly grew unmanageable. So I decided to spend some time to build myself the right tool for the job. I realized other people may have run into the same issues I had so I tought I'd release it to the App Store.

</comment><comment> non-entity I've been diving into digital communications, particularly VLC ([https://en.m.wikipedia.org/wiki/Visible_light_communication](https://en.m.wikipedia.org/wiki/Visible_light_communication))

There is some decent information out there about it including open source solutions and many good papers (unfortunately some paywalled) and I've been working on a very primitive prototype, but I've been pretty distracted. I've also ordered some books on VLC, digital communications that cover theory as well as some more applied ones. I do hate how many of the books are either textbooks or associated with standards that seem to make them very expensive.

Unfortunately sooner or later, I'll have to face my extremely weak math ability, which I'm dreading.

Behind that I have a ton of side projects backlogged ranging from more digital communications and hardware stuff, to retrocomputing projects, to some ML stuff I want to try.

</comment><comment><USER1236> My GitHub contributions have gone from 6 months of grey nothing to a forest of green, I think I'm using it as a coping mechanism.

Since my gym closed down, I decided to make a clone of the app it had been using for posting Workout of the Day and logging results, to keep learning more Flutter and try Firestore for the first time - I developed it entirely on Android but this is me trying it on the iPhone Emulator for the first time:

[https://www.youtube.com/watch?v=DvWJgZKj7cw](https://www.youtube.com/watch?v=DvWJgZKj7cw)

I've learnt so much from doing that, including implementing a signup/login flow with Firebase Auth, using Firebase Storage, how to get fancy with custom screen transitions in Flutter, how to implement, uh… that thing where a sticky UI element slides in/out as an overlay when you scroll down and up again - does that have a specific name?

I also went back to the basic Flutter VLC Remote app I wrote for myself a while back and having been adding as many features and as much polish as I can for the sake of learning:

[https://www.youtube.com/watch?v=8eXJX4GVGhA](https://www.youtube.com/watch?v=8eXJX4GVGhA)

I'm in the middle of redesigning its controls, having just figured out how to implement a nice full-width slider which acts as a floating divider between the playlist and controls. I've also started breaking out individual Flutter things I'm learning into a Codepen collection (titled with phrases I failed to find help with when searching for these things myself): [https://codepen.io/collection/nqpzvz](https://codepen.io/collection/nqpzvz)

I also brought the React/Preact/Inferno toolkit I created in the pre-create- react-app days back to life after an 18-month hiatus, by finishing the Babel 7 upgrade branch I started in January 2018. Despite what they say about the JavaScript ecosystem, Babel and Webpack were still at the same major version as when I stopped maintaining it!

[https://github.com/insin/nwb#nwb](https://github.com/insin/nwb#nwb)

It now has support for using the experimental build of React, the new automatic runtime in Babel's React transform which depends on it and the latest hot reloading implementation, which has come on leaps and bounds since I was away. Here's a recent demo of one of the main features I keep it around for:

[https://www.youtube.com/watch?v=U0DwgoYq5WI](https://www.youtube.com/watch?v=U0DwgoYq5WI)

I accidentally took a head-first dive into TypeScript type definitions and back into writing Babel AST transforms - a particular phrase ("host elements") in a tweet about not being able to use HTML attributes in React gave me an idea for a new major version of a Babel plugin I had written to do basic class → className and for → htmlFor transforms on JSX attributes:

[https://github.com/insin/babel-plugin-react-html- attrs](https://github.com/insin/babel-plugin-react-html-attrs)

It now lets you use _all_ HTML attributes on host elements in JSX, and I ended up spending too much of a weekend forking the React type definitions off the back of it, to add support for using all numeric and boolean HTML attributes and transforming them to the form React expects.

I've always wanted to learn some Lua, as my kids love Roblox and I'd like to try making games in Roblox Studio with them some time, so I wrote my first ever Lua script to do a fun thing in OBS:

[https://github.com/insin/obs-bounce#obs-bounce](https://github.com/insin/obs- bounce#obs-bounce)

At the start of April, Twitter broke my extension for making it halfway tolerable, so I went back to maintaining that, making it capable of stripping even more crap out of your timeline and making the separated Retweets timeline it adds to Twitter more robust:

[https://github.com/insin/tweak-new-twitter#tweak-new- twitter](https://github.com/insin/tweak-new-twitter#tweak-new-twitter)

I also dove much deeper into Gatsby than my previous experience with it of cloning and tweaking a blog template, as my wife needed to set up a marketing website quickly for a new business being spun out at her work. I've ended up with a setup which is easily reusable for the next site, easy to edit for non- technical users, and is zero cost for a really decent amount of functionality (mostly thanks to Netlify).

I even went back and resurrected my (OG) React Hacker News API client and added a new feature: a new story list containing every item you view the comment thread for, displayed in reverse-chronological order for ease of reading new comments on them:
