Tinder Social was (and remains) opt-out in Australia while he was writing the article. Even if Tinder Social is now opt-in in the US, the fact they were dismissive of the vulnerability disclosure is concerning.<p>Any social network with deteriorating privacy is bad. One where the content can potentially be sensitive is even worse. If you started on a service and it kept becoming more private by default, that&#x27;s fine - potentially annoying, but fine. If you start on a service and it kept becoming more public by default, then we have a problem.<p>The fact that Tinder don&#x27;t realize Tinder profiles may contain sensitive information for a significant portion of their user base is hugely disturbing. As stated in the article, there are so many circumstances beyond cheating that this is still an issue.<p>Assume for a fictional argument that I was born into a religious family, &quot;no sex before marriage&quot; type of thing, but enjoyed one night stands. One might use Tinder to do so quietly. Tinder didn&#x27;t allow your friends to see that information before - I assumed I was safe from judgement by my family and their friends. Then Tinder rips that privacy you thought you had away!<p>Saying that users should have known better is not an excuse. As developers we must operate under the assumption that best practices are likely going to be missed or misunderstood. Tinder violated that in an extreme way in an attempted land grab for a large social market beyond hook-ups and dating.<p>Disclosure: I&#x27;m friends with the author and commented on drafts.</text><parent_chain></parent_chain></comment><story><title>Stalking your Facebook friends on Tinder</title><url>https://defaultnamehere.tumblr.com/post/147747146865/stalking-your-facebook-friends-on-tinder#147747146865</url></story> |

I&#x27;m pretty sure implementing CSS from scratch (just looking at the specs) would take the average developer at least 10,000 hours. But in any case, why doesn&#x27;t the container query bind to a class? Having to name your container is so weird (we already <i>have</i> names: they&#x27;re called classes; and IDs; and DOM elements; and pseudo-classes; and aria labels; we need more!?).<p><pre><code> .special-wrapper {

If that&#x27;s such a pain point, I&#x27;d propose a :no-children-but-maybe-empty pseudo-class before you add a completely new feature to the language, :but-maybe-that&#x27;s-just-me.<p><pre><code> &#x2F;* Instead of.. *&#x2F;

If you took the time to actually assist somebody you were chastised in a weekly review where they went over your chat support. The person doing mine told me I had the highest satisfaction record in the entire company, and a &#x27;unique gift of clear and concise conversation, like you&#x27;re actually talking to them face to face&#x27; then said I&#x27;d be fired next week because my coworkers were knocking off hundreds of tickets a day just using automated responses, leaving their customers fuming in anger with low satisfaction ratings, as people are very aware of being fed automated responses but the goal was not real support, it was just clearing the tickets by any means possible. I decided to try half and half, so if the support question was written by somebody who obviously would not understand the documentation (grandma trying to sell a car), I would help them but just provide shit support to everybody else in the form of macros like my coworkers. Of course this was unacceptable and I got canned the next week as promised. Was an interesting experience, I can imagine DO having an insane scope to their support requests like &#x27;what is postgresql&#x27;.<p>Anyway imho you should have taken the support position and schemed your way into development internally.

It also allows the licensee (ala DropBox) let their company use, manage, display [etc] your files.<p>It's a fairly standard contractual term now days - for example see<p><a href="http://www.youtube.com/t/terms" rel="nofollow">http://www.youtube.com/t/terms</a> at 6 C OR even your Gmail Terms ...

This license is for the sole purpose of enabling Google to display, distribute and promote the Services and may be revoked for certain Services as defined in the Additional Terms of those Services."<p>Generally, the language uses "non-exclusive" in its context which is OK. It basically allows internet services to be internet services<p>i.e. if they didn't have a non-exclusive licence, how could they use your files - which contain copyright content you own - in their services ? - they couldn't :) By asking for a non-exclusive licence, it means you are permitting DropBox to use it for the purposes of<p>"worldwide, non-exclusive, royalty-free, sublicenseable rights to use, copy, distribute, prepare derivative works (such as translations or format conversions) of, perform, or publicly display that stuff to the extent we think it necessary for the Service."<p>If you're uncomfortable with this term, then unfortunately you'll be uncomfortable using any service on the Internet as it's generally required to provide a service :) The terms agreement incorporates their Privacy Agreement - thus meaning they still owe you the obligations outlined in their privacy clause. They cannot distribute your content without your permission.<p>"But, but, but .... they should have to identify copyright not me"<p>Again, you are giving them to non-exclusive right. If you have MP3 music [legally obtained for example] - you have ownership for that file. You are provided with the right to store that file for personal use just as you have the right to share that file with your friends. The rights associated with this file are governed by the terms of service when you purchased that file [i.e. iTunes]. Go and read your rights regarding MP3 Music purchased from iTunes.<p>You are providing DropBox with a non-exclusive right - not an "exclusive right" which would be just that "exclusive" and therefore you have licensed it only to DropBox per see - to be able to storage, transform ... etc that file. The Privacy policy is incorporated within the Terms agreement - thereby inferring they cannot "distribute your content without your consent".<p>Dropbox do NOT "know" where you purchased the file or the terms surrounding every single file they store on your behalf [how could they?] - it's your responsibility - not theirs - hence the point of the term.<p>"You must ensure you have the rights you need to grant us that permission."<p>Dropbox is fine.

The only job listing to even mention things like Rust in the region where I live in the past 5 years is Google, and they list it as “nice to have” on a recurrent phd position for c++ development.<p>Python is obviously a thing, but not so much for software development, but typically requires you to be a statistician first and then maybe capable of writing a little Python second.<p>So there is probably a bit of a disconnect between what is hip and what puts food on the table for a lot of us.<p>You’re probably on to a lot of it too. I recently got back into development, returning from a stint in management, project management and enterprise architecture and I’ve grown quite fond of typescript and the node environment.<p>It’s obviously a place where you can cause a lot of harm if you brute-force-program 100% or the time all of the time, but it’s also a place where you can create some great business value faster than I’ve ever experienced elsewhere. I mean, I can do things faster in Python but only until whatever I’m doing outgrows what I’m capable of keeping in my head.<p>That being said.

This sort of spending tugs at the heart strings but unfortunately it can actually be quite counter-productive at improving the lives of people in undeveloped regions.<p>By decreasing the amount of wealth that is necessary for a human person to remain alive - for example by introducing a new vaccine that allows a large (5+) family in unsanitary conditions to have all of their children reach adulthood - these sorts of programs in undeveloped countries actually create more poverty then they solve. There is not a cheap-manual labor shortage in these countries. There is however an acute shortage of well-paying jobs that don't involve corruption. By allowing the supply of just-surviving people to increase, you are putting even more downward pressure on the wages of unskilled labor (they are caught in the Iron Law of wages).<p>Keep in mind that in these countries, with no real legal system, unskilled labor doesn't mean gardening like it does in California but violence in the form of gangs/thug-ocracies who typically control access to natural resources or drug running routes. By creating more people, you are making it easier for the systems that keep them poor to grow, in a positive feedback loop.<p>The problem is not that a $3 drug is too expensive, and that we need to develop a 30 cent drug, the problem is that there are people who can't afford $3 for a life-saving drug. What they really need from the US is jobs, markets, and protection from the threats of climate change that we are causing by using 25% of the world's fossil fuels (more if you count the contribution from production in China to the cheap goods that we consume).<p>If Gates really wanted to help these people, he would campaign for an end to developed world farm subsidies, fossil fuel subsidies, and the recreational diamond market.

They define a function ZKSoK(c, w, r), and it would make sense not to use c, w, and r to mean anything else in the short definition of the construction. However, the authors chose to also use c for the hash used to make it non-interactive, and r_i for a series of random numbers. Using the same variable name for two different things makes it hard to work out what they mean, but as far as I can tell, the c that is the function parameter is public knowledge, w can be computed from public information, and ZKSoK does actually depend on the r that is the function parameter, and the validation of the proof does not actually check that S is correct (c is computed as c &#60;- g^S * h^r mod p, but it is useless if you can spend a zerocoin using any arbitrary S that doesn't actually correspond to any real c) as it claims.<p>In the 15 page version, they claim that the proof of the soundness of the ZKSoK proof can be found in "the full version of this paper" - perhaps that text makes things clearer, but they don't seem to provide a reference to it.</text><parent_chain></parent_chain></comment><story><title>Zerocoin: making Bitcoin anonymous</title><url>http://blog.cryptographyengineering.com/2013/04/zerocoin-making-bitcoin-anonymous.html</url></story> | <instructions>Your goal is to analyze the following comment and estimate how highly it will be upvoted by the Hacker News community.</instructions><comment><author>ezyang</author><text>Here is a puzzle for HNers.

We faced all these problems and had similar solutions to them all.<p>We even had a rapidly adapting network make-and-break recovery layer. You unplug your laptop from a wired connection, switch to wireless - we recovered in milliseconds. You heard barely a click.<p>The encryption issue is fun - we had a rotate-key message in-band. The receiver loaded new keys and tried them in sequence to ease the turnover time - out-of-order packets etc could make it ambiguous for a short while which key to use. A cache and aging keys out made it work pretty well.<p>Remixing on user stations proved to be problematic (mentioned elsewhere on this thread). You&#x27;d think if 6 people at one site were conferencing with a dozen elsewhere, you could elect one at each site to mix-and-forward. But corporate networks made it hard to determine who was &#x27;adjacent&#x27; - they were often layered and without uPNP (is that what the router protocol is called?) you couldn&#x27;t tell if somebody at the next desk was even in your company.<p>We had up to 100 people in a conference, and our enter-the-conference time was on the order of 100ms. Click into an all-hands, and be able to hear everybody before you finger left the mouse button. It was wonderful.<p>Sococo today is a sad shadow of that.

Came to find out that there are apparently two compilers, one from Intel and another from MS and the MS one is super-lenient about accepting garbage. Eventually worked out that the logic in the stock tables was such that several features (HPET and sleep, iirc) just straight up don&#x27;t work unless the OS identifies itself to ACPI as Vista (and not like Vista+, Vista exclusively).

I&#x27;ve been running a 2x&#x2F;192dpi Linux&#x2F;X11 laptop for a couple of years, and the experience has been near perfect. Hands down better than on Windows. Some DEs even detect the panel DPI and configure toolkit scaling automatically. Firefox and Chrome have been two of the most well-behaved apps, especially since they switched to GTK3, but it&#x27;s not just GTK3 that is well-behaved, Qt5 is as well. Since most apps I use are Qt5 and some are GTK3, they all get crisp HiDPI rendering automatically from the toolkit.<p>So I&#x27;m not sure what you mean by &quot;HiDPI on Linux is pretty much non existent.&quot; Maybe it gets worse if you need fractional scaling or displays with different scaling ratios, but these seem to things all platforms are struggling with. Microsoft only made built-in apps like File Explorer per-monitor-DPI aware in Windows 10 1703 (released a year ago), and macOS doesn&#x27;t attempt fractional scaling (eg. 1.5x, 2.5x, etc.) at all.</text><parent_chain><item><author>jhoechtl</author><text>HiDPI on Linux is pretty much non existent.

I ditched the T5XX series when they borked the keyboard layout by adding a numpad. Used to run Ubuntu, now I run Debian, stable or testing depending on point in release cycle at install time. I plan to take another look at Ubuntu now that they gave up on Unity. A coworker is happily on the T470s (first USB-C in the series). I always get 1920x1080 since my eyes are accustomed to it, but multiple coworkers are happy with 2560x1440. Used to get the Nvidia cards, now very happy with the integrated Intel graphics. In general, last year’s hardware requires almost zero messing with Linux to make everything work, whereas with the latest hardware, be prepared to solve a couple minor issues. Ubuntu’s font rendering or Infinality are both amazing and better than macOS or Win10 to my eyes.<p>I’m ridiculously excited to eventually upgrade to a T480s because it’s the first in the series to offer a quad-core CPU. They’re selling the quad-core with Intel graphics which is exactly what I want.

I always get 1920x1080 since my eyes are accustomed to it, but multiple coworkers are happy with 2560x1440. Used to get the Nvidia cards, now very happy with the integrated Intel graphics. In general, last year’s hardware requires almost zero messing with Linux to make everything work, whereas with the latest hardware, be prepared to solve a couple minor issues. Ubuntu’s font rendering or Infinality are both amazing and better than macOS or Win10 to my eyes.<p>I’m ridiculously excited to eventually upgrade to a T480s because it’s the first in the series to offer a quad-core CPU.

Notch is actually hot-swapping code, for example the code in the update function of the game, leaving the game state intact.

I&#x27;m not an EV hater, just pointing out here that even lithium-ion batteries are in the range of 100-265 Wh per kg while gasoline is around 12,200 Wh&#x2F;kg (roughly 50x the energy density). This is a big part of why there are no commercially-viable EV aircraft, and probably won&#x27;t be for some time -- namely until battery energy density improves by an order of magnitude or so.<p>As for this mini motorcycle, it&#x27;s impressive that it still looks pretty decent and someone unfamiliar with this model might even mistake it for stock. I never quite understood why it&#x27;s so hard to find even aftermarket tanks for bikes that get the range up to car range...I just want to go 500 miles on my bike without refueling. Put the gas in the frame AND into a 5+ gallon tank up top. Put gas into a portion of the seat. Put it up behind the headlight or in a big fender. Carrying jerry cans or even the bag style ones is just so bulky and inconvenient for overlanding on two wheels without a support vehicle carrying extra fuel.</text><parent_chain></parent_chain></comment><story><title>Honda Monkey Breaks World Record Covering 4,183 Km on Single Tank</title><url>https://www.advpulse.com/adv-news/honda-monkey-breaks-world-record-covering-4183-km-on-single-tank/</url></story> | <instructions>Your goal is to analyze the following comment and estimate how highly it will be upvoted by the Hacker News community.</instructions><comment><author>bergie</author><text>That is a long distance to make on a Honda Monkey!

Instance prices are all a race to the bottom among the providers, because servers are largely commodity hardware that&#x27;s easy to get from any number of providers, and it&#x27;s one of the first prices customers see, and often plays a big role in their choice of provider.<p>So that&#x27;s not where you make your profits. So you&#x27;re right, lots of revenue, but crucially, there is no real profit. There never will be. That makes it a boring product, not worth focusing a lot on from a marketing perspective etc.
Same tends to go for all of what you might think of as the basic building blocks of the cloud. e.g. object storage prices are often really close to what it actually costs to provide the service.<p>You make your profits on what you sell that runs <i>on</i> the cloud. All those additional things like databases, streaming services, kubernetes bits, functions etc. Those are where you make your actual profits. GenAI is a big potential profit driver for AWS, so that&#x27;s where they&#x27;re pushing. A couple of years ago it was &quot;$foo, but on Kubernetes&quot;. Before that it was &quot;$foo, but Serverless&quot;.
They&#x27;re just pushing where the profit and interest is, and pretty much always have done.<p>sort of side-note: Gartner&#x27;s evaluation of cloud providers got really absurd around kubernetes stuff. Because one cloud would do it, you&#x27;d miss out on points if <i>you</i> didn&#x27;t also add it, even if being on kubernetes literally added zero benefit, or arguably was worse. Same for &quot;Serverless&quot;. It didn&#x27;t matter if customers were actually using it, or wanted it, if AWS&#x2F;Azure&#x2F;GCP launched it, you&#x27;d better have it too.</text><parent_chain><item><author>cperciva</author><text>AWS is way too bandwagonny these days.

Some specific servers like SANs go direct 10GE, particularly if you're going to have 1-2 SAN interfaces and a bunch of clients (so you can use the 10GE uplink ports for it).<p>Enough things are CPU/memory/etc. bound that the "cheap" building block of a 1-2CPU server with 4GE, RAM, and some local disk is still more appropriate than buying a Xeon E7 with 10GE HBAs, in most cases. There might be an exception if you have per-host vs. per-core licensing for expensive stuff, or other artificial complaints, or a specific component (database?) which doesn't horizontally scale.<p>I predict $5k 40-port 10GE switches and commodity server on-board 10GE NICs in a couple years, though. Although at that point, you need something crazy to uplink the switches. 40GE is emerging, or you could use a non-ethernet option. SANs are the big application for 10GE now since you can comfortably fit all the clients and servers on a standard 10GE switch and don't need to uplink most of the traffic. Part of the issue with the higher speed ethernets is lack of a copper cabling option, particularly one which works with existing cable plants.

Unfortunately doing that correctly can be really challenging. Despite several misleading doom-and-gloom articles written today (<a href="http:&#x2F;&#x2F;fortune.com&#x2F;2017&#x2F;07&#x2F;25&#x2F;sec-says-digital-tokens-are-securities-warns-of-fraud&#x2F;" rel="nofollow">http:&#x2F;&#x2F;fortune.com&#x2F;2017&#x2F;07&#x2F;25&#x2F;sec-says-digital-tokens-are-se...</a>) the SEC has not said that all tokens are securities. Rather, application tokens are a promising new technology that enable all kinds of use-cases, each one unique from the next, and each having a unique &#x27;regulation profile&#x27;. It would be very short-sighted to apply broad sweeping legislation and with this ruling, it&#x27;s clear that the SEC also feels the same.<p>Just like mifeng mentioned, it really is a facts and circumstances determination per token. Given we had to build all of the token sale scaffolding (legal, tech, etc.) for Filecoin, it made sense to open this up to other technologists as well. Our hope with CoinList is that creators can focus on building awesome tech and expanding the valuable uses for application tokens while reducing the amount of time and resource they need to spend making sure they stay within the parameters of the law.
Filecoin may be limited to accredited investors for this particular sale, but that&#x27;s not to say other tokens that use the platform in the future would be required to do the same. Ultimately the decision is up to the creators, but they should be very well educated on the implications of what those choices could mean.</text><parent_chain><item><author>mifeng</author><text>If you read the actual report (<a href="https:&#x2F;&#x2F;www.sec.gov&#x2F;litigation&#x2F;investreport&#x2F;34-81207.pdf" rel="nofollow">https:&#x2F;&#x2F;www.sec.gov&#x2F;litigation&#x2F;investreport&#x2F;34-81207.pdf</a>), you may notice that the SEC is careful to apply securities law DAO specifically.<p>In particular, they apply the security test: &quot;did investors invest money with a reasonable expectation of profits derived from managerial efforts of others?&quot; Since DAO was a wisdom-of-crowd VC fund, the answer is a clear YES.<p>On the other hand, they are careful to say that other token sales <i>MAY</i> be securities but will be treated based on their specific facts and circumstances.<p>My takeaway is that this doesn&#x27;t change anything. The SEC is proceeding cautiously: applying securities law in clear-cut cases, &quot;studying the effects&quot; generally.<p>It&#x27;s also not a bad thing to comply with securities regulation.

Does that count as expectation of profit?</text><parent_chain><item><author>mifeng</author><text>If you read the actual report (<a href="https:&#x2F;&#x2F;www.sec.gov&#x2F;litigation&#x2F;investreport&#x2F;34-81207.pdf" rel="nofollow">https:&#x2F;&#x2F;www.sec.gov&#x2F;litigation&#x2F;investreport&#x2F;34-81207.pdf</a>), you may notice that the SEC is careful to apply securities law DAO specifically.<p>In particular, they apply the security test: &quot;did investors invest money with a reasonable expectation of profits derived from managerial efforts of others?&quot; Since DAO was a wisdom-of-crowd VC fund, the answer is a clear YES.<p>On the other hand, they are careful to say that other token sales <i>MAY</i> be securities but will be treated based on their specific facts and circumstances.<p>My takeaway is that this doesn&#x27;t change anything. The SEC is proceeding cautiously: applying securities law in clear-cut cases, &quot;studying the effects&quot; generally.<p>It&#x27;s also not a bad thing to comply with securities regulation. FileCoin is doing quite well selling only to accredited investors on CoinList.</text></item></parent_chain></comment><story><title>SEC Issues Report Concluding DAO Tokens, a Digital Asset, Were Securities</title><url>https://www.sec.gov/news/press-release/2017-131</url></story> |

It would be logical for the FAA to relax the GPS requirement slightly, so a cheap GPS module is sufficient to alert nearby aircraft of RPV activity over a certain altitude (eg. 200ft AGL) These RPV-grade ADS-B transponders could use a limited signal output, to avoid nuisance pop-ups from longer distances. The transponder Mode-S ID uniquely identifies the RPV.<p>It would be possible for a transponder to use an alternate channel frequency, similar to how many General Aviation aircraft use 978Mhz ADS-B. Even with an alternate RPV channel, the RPV operators would still be alerted to regular aircraft operations.</text><parent_chain></parent_chain></comment><story><title>U.S. Will Require Drones to Be Registered</title><url>http://www.nbcnews.com/news/us-news/u-s-will-require-drones-be-registered-n446266</url></story> | <instructions>Your goal is to analyze the following comment and estimate how highly it will be upvoted by the Hacker News community.</instructions><comment><author>MichaelApproved</author><text>I love the progress <i>drones</i> have given our society.

This is perfectly timed since I’m currently evaluating device management solutions for Hiome’s IoT device fleet (<a href="https:&#x2F;&#x2F;hiome.com" rel="nofollow">https:&#x2F;&#x2F;hiome.com</a>)<p>Currently, we use Mender (mender.io) but are considering switching.<p>Pros for Mender:<p>* great pricing for consumer products at around $0.50&#x2F;device&#x2F;mo<p>* lets us keep using Raspbian on our Raspberry Pi fleet<p>The cons however are that we are stuck with Raspberry Pi 3B+. We want to switch a more production-friendly board (either the compute module or something else entirely), but that means switching to yocto, which as you mentioned, is its own world of problems. Mender’s UI is also very buggy.<p>BalenaOS is acceptable and does support the boards we’re currently considering, but we’re limited to the devices they choose to support in the future.<p>I love that Deviceplane claims to work with any linux distribution. However, as far as I can tell, you only support application updates, not OS-level updates. Will it ever be possible to update the OS in your model? A major reason I want to use a device management system is to make sure we can fix potential OS-level security issues.<p>Another concern is pricing. $5&#x2F;device&#x2F;mo is probably fine for enterprise, but that can be 100% of revenue for many consumer devices. Since you’re open source, we could always self-host, but I’m curious if you have any plans to for more B2C-friendly pricing.</text><parent_chain></parent_chain></comment><story><title>Launch HN: Deviceplane (YC W20) – Update and Manage Devices Running Linux</title><text>Hey Hacker News! We&#x27;re Josh, Sean, and Cyrus from Deviceplane (<a href="https:&#x2F;&#x2F;deviceplane.com&#x2F;" rel="nofollow">https:&#x2F;&#x2F;deviceplane.com&#x2F;</a>).<p>Deviceplane is an open source device management tool for embedded systems, IoT, and edge computing. More specifically, we manage any device running Linux. These can be found in many different categories of hardware such as single-board computers (Raspberry Pis, Jetson Nanos), IoT devices&#x2F;gateways, and servers running at the edge.<p>The use cases for Linux devices span many different verticals&#x2F;industries: robotics, consumer appliances, drones, autonomous vehicles, medical devices, and much more. Your first thought might be that a tool for managing robots and a tool for managing medical devices are quite different, but after talking to a variety of companies, we&#x27;ve found that the pain points across these industries are actually quite similar!<p>Deviceplane solves the biggest infrastructure problems for these use cases:<p><pre><code> - Orchestrating and deployment of remote updates
- Network connectivity and SSH access
- Host and application monitoring
- Device organization: naming, labeling, searching, and filtering of devices
- Access and security controls
</code></pre>
Deviceplane is designed to support a variety of hardware, from small embedded devices to large x86 servers. Today’s tooling ecosystem suffers from being segmented by hardware size.<p>For smaller devices, the Yocto project is popular. While it&#x27;s good for building custom Linux installations, it has downsides for delivering applications. It&#x27;s hard to understand, can take hours to compile, and solves only a portion of the problems present in device management.<p>For larger devices, many companies seem to build and maintain their own internal tooling. We&#x27;ve seen everything from systems built around configuration management to scripts polling for new Debian packages in S3. These systems are usually brittle, fall short of a complete feature set, and drain precious engineering resources with their maintenance.<p>We think Deviceplane is a great replacement for all of these. Not only is it suitable for all of these hardware sizes, it also presents a way to standardize the tooling across them.<p>One of our goals with Deviceplane is to make device management more accessible to developers. To do this, we build on technologies and concepts popularized in cloud deployments:<p><pre><code> - Applications are packaged as containers and defined in a format resembling Docker Compose
- Updates can be rolled out and tested gradually by using &quot;canary&quot; deployments
- An intuitive and scriptable CLI that will feel familiar to Docker and Kubernetes users
</code></pre>

We&#x27;ve now containerized our applications and can schedule releases, stream metrics and crash data to datadog, all of which makes us feel more confident in our IoT.<p>The only feature I miss is being able to execute bulk scripts across devices, and would love to have an internal dashboard rather than using datadog since the cost of data collection is beginning to scale out of hand.</text><parent_chain></parent_chain></comment><story><title>Launch HN: Deviceplane (YC W20) – Update and Manage Devices Running Linux</title><text>Hey Hacker News! We&#x27;re Josh, Sean, and Cyrus from Deviceplane (<a href="https:&#x2F;&#x2F;deviceplane.com&#x2F;" rel="nofollow">https:&#x2F;&#x2F;deviceplane.com&#x2F;</a>).<p>Deviceplane is an open source device management tool for embedded systems, IoT, and edge computing. More specifically, we manage any device running Linux. These can be found in many different categories of hardware such as single-board computers (Raspberry Pis, Jetson Nanos), IoT devices&#x2F;gateways, and servers running at the edge.<p>The use cases for Linux devices span many different verticals&#x2F;industries: robotics, consumer appliances, drones, autonomous vehicles, medical devices, and much more. Your first thought might be that a tool for managing robots and a tool for managing medical devices are quite different, but after talking to a variety of companies, we&#x27;ve found that the pain points across these industries are actually quite similar!<p>Deviceplane solves the biggest infrastructure problems for these use cases:<p><pre><code> - Orchestrating and deployment of remote updates
- Network connectivity and SSH access
- Host and application monitoring
- Device organization: naming, labeling, searching, and filtering of devices
- Access and security controls
</code></pre>
Deviceplane is designed to support a variety of hardware, from small embedded devices to large x86 servers. Today’s tooling ecosystem suffers from being segmented by hardware size.<p>For smaller devices, the Yocto project is popular. While it&#x27;s good for building custom Linux installations, it has downsides for delivering applications. It&#x27;s hard to understand, can take hours to compile, and solves only a portion of the problems present in device management.<p>For larger devices, many companies seem to build and maintain their own internal tooling. We&#x27;ve seen everything from systems built around configuration management to scripts polling for new Debian packages in S3. These systems are usually brittle, fall short of a complete feature set, and drain precious engineering resources with their maintenance.<p>We think Deviceplane is a great replacement for all of these. Not only is it suitable for all of these hardware sizes, it also presents a way to standardize the tooling across them.<p>One of our goals with Deviceplane is to make device management more accessible to developers. To do this, we build on technologies and concepts popularized in cloud deployments:<p><pre><code> - Applications are packaged as containers and defined in a format resembling Docker Compose
- Updates can be rolled out and tested gradually by using &quot;canary&quot; deployments
- An intuitive and scriptable CLI that will feel familiar to Docker and Kubernetes users
</code></pre>

And like the other frameworks in other comments here, it&#x27;s a good enough start in a small company, start up, or small department within a larger organisation.<p>A better framework might be cobbled together from various disciplines. For instance, &quot;Understand&quot;. This part is huge. Well, bigger than those three questions the author lists.<p>&quot;Understanding&quot; begins by stepping back to look at the environment as a whole. Bound the situation. Assess organisational culture, the environment (immutable aspects of a transformation&#x2F;process), the organisation&#x27;s technology landscape (Active Directory?), regulatory requirements, competition, suppliers and customers.<p>There&#x27;s also the social system (roles, norms, values), and the political landscape.<p>Then you define your objective. But before you can do that you need to know who your client is. Sure, in SV that&#x27;s often easy. Outside that bubble not so much. Identify the client by asking some questions - whom do you need to satisfy? Who will judge the success of the project? Who will fail if the project fails? Who has authority for the project? Who pays for the project? Whom do you report to?<p>After all that you&#x27;re ready to set an objective. Vision&#x2F;scope stuff. Specific, measurable, attainable, realistic and time-boxed. Cliche&#x27;d, but when a project goes wrong the specification is the only version of the truth a team has to fall back on.<p>Setting project objectives is much bigger than I can do justice to here. However once you have that you can start with the fun stuff. Design, build, deploy, repeat until done.<p>However while you&#x27;re doing the fun stuff you still have to do the unfun stuff too - risk management, and stakeholder management. And it&#x27;s stupefyingly incredible how many people think they know how to do these things but can&#x27;t readily explain the difference between mitigation and contingency, exposure and impact, or why you have to be nice to the CIO for your project to succeed, even though the CTO and CEO are on your side.<p>I&#x27;ve written about all this stuff. <a href="https:&#x2F;&#x2F;www.wittenburg.co.uk&#x2F;Entry.aspx?id=8ec91ced-b3a4-4b07-bf91-17f0efda1718" rel="nofollow">https:&#x2F;&#x2F;www.wittenburg.co.uk&#x2F;Entry.aspx?id=8ec91ced-b3a4-4b0...</a></text><parent_chain></parent_chain></comment><story><title>Understand, Design, Build: A Framework for Problem-Solving</title><url>https://lob.com/blog/understand-design-build-a-framework-for-problem-solving</url></story> |

In blackjack with basic strategy your expected value is, what, 49%? Craps, it&#x27;s similar. Just look it up. Nobody at the table playing, or even running the show, can manipulate the outcome except by changing the parameters of the game as posted in the (I assume) regulated odds boards.<p>Investing in an unregulated market is absolutely nothing like that. Your outcome is undefined, but you&#x27;re subject to front-running, tape painting, wash trading, fake news stories and tens of other well-known scams.<p>The regulations aren&#x27;t to stop the poor from making money. If it were a sure-fire way to make money, everyone would just do it all the time. It&#x27;s the Trumpian &quot;trade wars are easy to win&quot; argument. If it&#x27;s easy, everyone would win, so nobody would win, end of story. It&#x27;s to limit people to what they can afford to lose (or at least try). And it&#x27;s done in the social good also, as people who become insolvent then utilize the social safety net to get back on their feet.<p>Yes, we need the real consequences, and what you&#x27;re describing is literally regulation.</text><parent_chain><item><author>bufferoverflow</author><text>This whole regulation is unneeded.

For the former, I feel like people know going in that the odds are in favor of the house and they come to terms with that by saying to themselves that its entertainment. In other words, they kind-of expect to get screwed.<p>In business investing its the opposite. They really do think they stand a chance at making millions even when the odds may actually be worse than gambling in some cases, especially if they fail to do their due diligence.<p>So maybe instead of regulation we simply need a legal, notarized document signed for every investment that states &quot;I am aware that I stand a very high chance of losing all of my money and relinquish my rights to sue anyone involved unless outright fraud has been established.&quot; Probably still wouldn&#x27;t work, but its worth consideration.</text><parent_chain><item><author>bufferoverflow</author><text>This whole regulation is unneeded.

Which makes it, in one sense, kind of like what ggplot2 was to R&#x27;s standard plotting tools.<p>However, Seaborn has a more object-oriented API, among other things:<p><a href="http:&#x2F;&#x2F;stanford.edu&#x2F;~mwaskom&#x2F;software&#x2F;seaborn&#x2F;introduction.html" rel="nofollow">http:&#x2F;&#x2F;stanford.edu&#x2F;~mwaskom&#x2F;software&#x2F;seaborn&#x2F;introduction.h...</a><p>&gt; Seaborn’s goals are similar to those of R’s ggplot, but it takes a different approach with an imperative and object-oriented style that tries to make it straightforward to construct sophisticated plots. If matplotlib “tries to make easy things easy and hard things possible”, seaborn aims to make a well-defined set of hard things easy too.<p>There already is an attempt to port ggplot over to Python, and its authors&#x27; opinion is that its API should look like R&#x27;s ggplot2, which means the syntax is not Pythonic: <a href="http:&#x2F;&#x2F;ggplot.yhathq.com&#x2F;" rel="nofollow">http:&#x2F;&#x2F;ggplot.yhathq.com&#x2F;</a></text><parent_chain></parent_chain></comment><story><title>Seaborn: a high-level Python interface for drawing statistical graphics</title><url>https://github.com/mwaskom/seaborn</url></story> |
