Ask HN: Idea Sunday - <AUTHOR> A HN experiment. Every Sunday, a thread will be started to share product ideas. Why? Because many people have ideas they will simply not have the time to implement, and many need product ideas to work on.
If you think this thread should be started only every other Sunday or monthly, please state it in your comment. <comment><USER3> I'd like to see a site that focuses on the construction of logical arguments supporting various political and non-political views.

I'd like for the system to allow for continued refinement of arguments on various topics and to allow for various branching of thought. That is, I'm not looking for a democracy that rewards majoritarian thought and punishes less popular but logically consistent argumentation.

As an end product, if I'm discussing, say, gun control with someone, I should be able to give them a URL: [http://www.xyz3323499.com/crusso/gun_control/](http://www.xyz3323499.com/crusso/gun_control/) and all of the arguments and important information that I have upvoted, added to, or edited would show up.

Most of this stems out of my frustration with the tedious nature of arguments on the internet. New stories stir up old arguments. Forums like HN tend to rehash all those old arguments with often little thought for the mountains of arguments/evidence already out there. Rather than have new stories refine or even change arguments and their conclusions, most people on the internet just chase their tails in circles.

I'd view this kind of site as a "let's stand on each others' shoulders and provide our shoulders to others" kind of work. With a decent web of trust, I should be able to look at the arguments of the most "respected" members of the site and mix-in their arguments with my own.

I think that a sufficiently complex web of trust would allow for fundamentally different viewpoints on a given issue to thrive because the spheres of supporters of those viewpoints have different value systems. Even with those different value systems, it should be possible at some point to pick out the thought leaders across different spheres that transcend typical Republican, Democrat, Liberal, Conservative, Theist, Atheist labels with arguments that are acknowledged across the board as being internally consistent and factually based.

Yeah, I realize that I've rambled -- but if someone finds value in the idea and runs with it, I'd love to see it out there.

<comment><USER4> I appreciate the idea, but it needs some reworking.

In particular, I see two big flaws.

(1) The essence of the use of this site would be that one chooses a position, and then finds arguments to support it. In other words, "I've made up my mind; now show me why I'm right."

Now suppose I'm the person discussing an issue with you. Why should I pay any attention to some page chosen based largely on the assumption that I'm wrong?

(2) You say "... I'm not looking for a democracy that rewards majoritarian thought and punishes less popular ...." And then you apparently want to use something along the lines of up/down voting to judge arguments. That's not the way to get what you say you want.

In short, the idea, as stated, strikes me mostly as a tool for increasing polarization.

More beneficial would be a site that simply provides information to help make decisions on whatever issues are of interest. To go with the gun-control example, you could have links to -- or summaries of -- studies on the effect of gun control. You could have comparative data on rates of various crimes in locations with different gun laws. Etc.

How do deal with (2) is a harder problem. The plague of voting-based-on- agreement that makes sites like HN & Reddit so much worse than they could be, is something I wish more people were trying to address.

<comment><USER5> I have some ideas for improving the efficacy of online voting systems, but starting a new online community is hard. Even just starting a subreddits is hard, and I imagine that to be lower-friction than creating a stand-alone site, given Reddit's large existing user base.

If you have an online-community that you run and would like some ideas to combat vote-based-on-agreement, here are a few that I've thought up or come across:

(Not claiming that these strategies are ungameable).

* Limit the number of upvotes a user can give per day, thus making votes more valuable.

* Force users to space-out voting, allowing only 1 upvote every 5 minutes.

* Vote value: Votes are valued more the less you do it over a certain period - so if you only upvote once per-day, that post gets more points than if you upvoted everything in /new. Choice: Do it hidden on the backend, or could be interesting; do it in a user-configurable format. Give users, say, 100 points per-day and are allowed to upvote transparently - you can give one thing 100 points or four things 25 points.

* Time-delayed voting: votes are only allowed after a certain amount of time has passed since you clicked on a link. A well thought-out and reasoned article should take at least a couple of minutes to read, so I can upvote that after I read; I'm not likely to wait around to upvote an image-macro with fewer than a dozen words unless it's _really_ special.

* Karma cap, both negative and positive: Limit max positive karma to something low, say 50. That's high enough to see that a user isn't brand new but isn't trivially attainable. That way, it's fine to get to the cap, but posting inane one-liners attempting to reap thousands of points for a single comment isn't so tempting. Limit negative karma to something lower, like -100 to dissuade trolls, while still showing that a user is disagreed with. Hopefully that encourages discussion for the sake of discussion.

* Meta-voting: You vote on how many points a post got, so if a pithy but well-timed comment that says "lol butts" gets a lot of points, you can vote to say that the post didn't deserve those points. Make this a limited power granted to a select (but changing) group.

* Make downvoting cost karma: If it cost karma to downvote, that could be a higher bar to drive-by-disagreeing.

* Not sure if it's a good idea, but turn the script around. Instead of trying to avoiding the Pepsi-Blue Advertising syndrome, charge money for votes transparently adding points to a post or comment. As users can still downvote items, it becomes expensive to elevate a bad piece of advertising. Maybe extend this to users by allowing users to receive money for lots of highly-rated comments. Or perhaps use Dogecoin as your currency of choice as the real-world value of 1 Doge is so low that it's effectively free in small quantities, but not actually free.

I don't think allowing the masses to vote on things is a bad idea, but it's an idea that needs some refinements for best effect.

I'm sick of dealing with scheduled events, timezones, future background jobs, etc. in almost every app I build. I want a service with an elegant API and nice libraries that would let me:

* Create multiple calendars (it would have an ID I could then save with my user model or whatever)

* Add events to a calendar by just passing it a timestamp and other metadata

* Have webhooks that get called any time an event starts/stops (possibly also X minutes before)

* Nice API calls for getting all a calendar's events, checking free/busy times, specifying time zone output and strftime formatting, etc.

* A JS library for outputting pretty calendars to an HTML page

* An additional cron-like feature for each calendar allowing you to define recurring webhooks

If anyone wants to give something like this a shot, let me know. I'll be your first customer, partner or angel investor.

<comment><USER7> Just out of curiosity, isn't this already possible with the Google Calendar API?

<comment><USER6> I haven't looked that deep into the most recent version of G's calendar API. I don't think they have webhooks though.

<comment><USER7> Actually they do in v3 [https://developers.google.com/google- apps/calendar/v3/push](https://developers.google.com/google- apps/calendar/v3/push)

<comment><USER8> Does it allow you to create Calendar as a data object whenever you want to create one or is it just one calendar associated with one google account ? Because what if I don't want to create google account for my users , just get the calendar functionality.

<comment><USER9> You can create multiple calendars but they are always associated with a user's google account. You don't want Stripe for calendars, but rather Balanced for calendars. A whitelabel calendar API where you user's dont have to sign up for another service in order to use yours. Correct?

<comment><USER8> Correct!

</comment></comment></comment></comment></comment></comment></comment><comment><USER10> We like experiments and this is a good one that goes to HN's core. Also, "Idea Sunday" is a great name.

I don't see why there shouldn't be a thread like this every Sunday, as long as the quality is good. If there aren't enough new good ideas, we can reduce the frequency. Consider yourselves challenged!

If it is to become a regular thing, we'll ask the whoishiring account to post them. That's the only account allowed to make recurring posts like this, which solves the problem of users competing to do it for the karma. Maybe rokhayakebe can keep posting these for another few weeks and, if it's still going strong, we can semi-formalize it then.

<comment><USER11> What I'd love to see is some kind of "meta" HN where all the ask HN, show HN and similar threads are posted. For two reasons: 1) those "meta" threads might gather to a different audience and 2) many people are more interested in normal threads, and many are interested in the meta.

One could just go ahead and create a site for that, but obviously it wouldn't have the same traction as HN, and 99% of the value of HN is in the people posting here.

I do realize that it will not get implemented, but maybe consider this :) Maybe instead of creating a new section of the site, make those meta thread listen under an url like [https://news.ycombinator.com/meta](https://news.ycombinator.com/meta), so that one interested could see the latest threads without much effort.

<comment><USER12> And one for bitcoin! And one for nodejs! And x, and y and z! You know what, let's put them in a subdirectory, like so: /h/bitcoin or /h/meta. And we call them sub-HNs!

 _..._

<comment><USER13> Although a _sub-HN_ approach sounds appealing at face-value, it's likely to fragment the site content a little too much.

One of the things I appreciate most about HN is its ability to act as a filter with single point of convergence. I'm not sure I'd want to sacrifice that (personally), probably nothing more than for 'fear of missing out'.

<comment><USER14> Pretty sure he was being sarcastic, referencing reddit, subreddits, and the /r/ url schema.

</comment></comment></comment></comment></comment><comment><USER15> I think it would be interesting to have an app that determines the optimal times to stop for gas during a trip. Especially when you are traveling across state lines, gas prices can vary a pretty decent amount.

The simple version:

\- Once you're under a certain amount of fuel (1/3 of a tank?), you open the app, and tell it you need to get gas within the next n miles. The app checks gas prices along your route (does gasbuddy have an api?), and tells you which gas station you should stop at.

The complex version:

\- The app connects to your car with an OBDII device via bluetooth (they are pretty cheap), automatically watches how much gas you have left, and determines the optimal place to refuel once you are under 1/3 of a tank. Basically, you would be able to open the app at the start of your trip, and it would alert you a few miles before the best exit to get gas.

</comment><comment><USER16> Commitment device app that works on a dead man's switch. The idea is to use the discipline you have now to discipline your future self.

eg1 - Enter your weight every month. If you go over a predetermined weight, it does something punitive. Posts embarrassing pictures online, emails your mom, donates $50 to the Klu klux Klan.

eg2 Create a todo list with due dates, goals or somesuch. Failing to complete them does something punitive.

eg3 Create out a challenge (exercise 5 times per week). Failure to complete challenge does something punitive.

The key is to get the psychological component right. I think if someone's daily task is 100 or more pushups they are more likely to fraudulently push a complete button than they are to enter a fraudulent number of pushups.

Could be a fun project.

<comment><USER17> You might enjoy this story / podcast: [http://freakonomics.com/2012/02/02/save-me-from-myself-a- new...](http://freakonomics.com/2012/02/02/save-me-from-myself-a-new- freakonomics-radio-podcast/)

One guy decided that he wanted to get healthy. So, he made a list of prohibited foods and actions and wrote a check for $750 payable to Oprah Winfrey (he dislikes Oprah for some reason).

He told his wife, "If I do anything on this list in the next 30 days, send this check to Oprah, no exceptions."

<comment><USER16> I think I may have gotten the KKK idea from freakonomics podcast, might have been this episode. The Oprah things sounds familiar too.

</comment></comment></comment><comment><USER18> Lower ligature risk USB charging cables. These would be used by mental health hospitals to allow (risk assessed) patient to charge their devices without introducing ligature risk.

To go along with this:

Bulk USB charger. Imagine a 20 port USB hub, but this has no USB connectivity. It only has USB power. It would be kept in a secure place in a mental health ward and would allow them to charge patient's devices. This would mean that patients get electronic devices but without having access to cords (ligature risk) or mains plugs (self harm risk).

(Take a UK 3 pin plug. Place it on floor with prongs up. Jump off bed onto plug with weight on one foot. That's an unpleasant injury. Removing that risk is useful).

Advantages:

You don't need to PAT test each charger coming into the hospital. You reduce (slightly) fire risk from bad quality chargers.

You reduce ligature and self harm risk.

You allow patients access to electronic devices which has some "safeguarding of liberties" benefits.

Disadvantages: selling to the NHS is possibly hell, and selling electrical equipment to the NHS is possibly even harder.

You're creating a vigh value stash of easy to steal equipment. MH hospitals already have lots of IT and stealable medication so they should be able to keep it safe but maybe a ventilated safe would be part of the package.

<comment><USER19> wouldn't it just be a matter of using a shorter cable like 4" or less?

<comment><USER20> Or a strong magnetic connector every 10 or so inches to allow you to build a cable as long as you like? (I have no idea if that's actually possible)

<comment><USER21> Swallowing strong magnets is pretty dangerous.

</comment></comment></comment></comment><comment><USER22> I have a hard time explaining this idea, so please bear with me.

As a founder and hacker, I want to know how my users use my web and mobile apps. But I haven't found an intuitive and dead-simple way to do it.

Mixpanel and google analytic are way more complex than what I have in mind.

What I would like to have is more similar to Facebook, but instead of looking at my friends activity, I'd like to see what's happening with my users.

I like the idea of a feed, or more specifically an exploratory object graph.

I'd like to open my phone and see a feed of what's happening, similar to a cat | tail but where I could click on a verb (Joined the website) or a noun (10 users) and it would direct me to that specific page.

So, for instance, it would tell me:

15 users joined <My service>. Bob And Alice got a new highscore of 2500. Marie played level 3 10 times.

I could change the Zoom ratio.. I.e. see the feed of the last minute or the last year, and it would sum up the actions to one statement.. "1541 users upgrated to premium", etc.

Basically, I don't want to look at graphes or stats or parse log files, I just want a beautiful and simple feed of what's happening. And when I see something that I'm curious about, I can just click and learn more. Just a dead simple way to understand how my users use my apps.

<comment><USER23> I like it. It is like Mixpanel, the implementation on the page would be similar, but without data aggregation.

There are open-source Mixpanel-like backends out there, some will not come with a frontend full of charts, you should just get one of these and build a frontend full of feeds.

</comment></comment></comment><comment><USER24> A service that figures out how to create and deliver healthy (meaning not extremely salty, sugary, etc.), same-day-prepared, vegetarian-friendly meals for $10 USD per day or less. The service would make one or two dishes so that they can be prepared in batch (maybe one non-vegetarian, and one vegetarian), and deliver them at a predetermined time. The current services in this industry tend to cost a lot more than this and/or require you to do preparation yourself (i.e., they supply the ingredients only.) Even better: if you can accept the delivery soon after "cook time", you can get your meal warm, assuming it's not a cold dish to start with.

For people who don't, can't, and won't cook, and realize that much restaurant food isn't focused on trying to balance taste and health, this would be a great service. $200/month, 5 days a week. The logistics part seems feasible based on what's current in the marketplace; the economics are an open question.

<comment><USER25> Does Sprig or Spoonrocket or the other alternatives not deliver healthy food? I believe they have a vegetarian option.

<comment><USER24> Spoonrocket looks the closest (CA only for now, I'm in NYC), so thanks for that. I'll keep watching them. I couldn't find a subscription option for Sprig; the others mentioned upthread were "ingredients only" services. Looks like this model is getting closer, though.

I think that a company like Spoonrocket experimenting with a subscription service would be worth trying - the companies would have steadier income, and customers wouldn't have to think about it unless they didn't want the daily meal.

</comment></comment></comment><comment><USER26> While we're at it * :

Funding Monday - where everyone pitches to VC's in the same HN thread.

Trial Tuesday - where everyone provides a link to their demo in the same HN thread.

Writing Wednesday - where everyone writes an informative hacker-related topic on their blog and shares a link to it in the same HN thread.

Throwback Thursday - where people all share something informative about past experiences or past apps/etc. in the same HN thread.

Free Work Friday - where people request work to be done by volunteers to develop their product with a possible chance at employment at some future date all in the same HN thread.

* - with slight sarcasm

<comment><USER27> I like some of these ideas. The Trial Tuesday could be a nice way for people to get feedback on their WIP projects and perhaps motivate them to keep up and have weekly updates.

<comment><USER28> that's a great idea. get together a community who will each publish an update/demo on their project each week on the same thread. I'd certainly be up for joining in; it might shame me out of letting side-projects sit untouched for a month at a time.

</comment></comment></comment><comment><USER11> Okay, a bunch of ideas. Probably nothing as good as my last one ([https://news.ycombinator.com/item?id=7542610](https://news.ycombinator.com/item?id=7542610)), which was meh to begin with (but I'm happy to see that it sparkled a bit of interest).

#1) An anonymous blogging platform. A site that obviously doesn't log you, and that allow you to publish posts without having them attached to an username. Since many would like to somehow post under the same handle, but without having the post attached to an username, implement a system like tripcodes on 4chan (for anyone that's not familiar, you choose a random string, and then you get an "username" derivated from that string. No passwords, no login. As long as you're the only one that know the original string, you are the only one that can post under that "tripcode"). Problems: Money, it's hard to make profitable an anonymous site. Useless, it's not that hard to pick a random name and create a blog on wordpress.com, blogger or similar while using tor. Spam, a site where one can post anonymously without hassle is just asking for it.

#2) (totally inspired by Idea Sunday, but I've had this idea before for a while) a site to post ideas for a project, or a "I'd totally love if someone where to do this". Then implement a rating system or something similar, so that the most common/interesting ideas are always at the top. And a random button to get a random idea (ideas as service!). Call it "Jar for ideas" or similar :)

<comment><USER29> #2) Something like [http://www.reddit.com/r/somebodymakethis](http://www.reddit.com/r/somebodymakethis) ?

</comment></comment><comment><USER30> I had a small discussion about this idea[1] and I believe that it is worthwhile:

Make private key based authentication useful for logging in to websites. I don't have the chops but introducing private key based auth as an extra can be very worthwhile for some users. So start there and improve the UI until your grandmother can use it.

I believe the biggest hurdle will be private key management. The advantage of using private keys for authenticating with web services that if the keys become unrecoverable the keys can actually changed by the service provider (after sufficient diligence).

<comment><USER31> You know client certificates can be used for this, right?

<comment><USER32> Having spend the last week or so working with client certificates, they could be so much more if browsers implemented a proper interface for managing them, or at least a much more intuitive one than they do at the moment. They work spectacularly for building closed APIs where you control both sides, however. They're just a bit tricky for the end user most of the time

</comment></comment></comment><comment><USER33> A usability test of mobile apps delivered to consumers through ad space on free mobile games.

You create a "use quest" of your mobile app. One or more screenshots of your application with a stated goal - e.g. invite a friend on a social app. You present the user the home screen and he has to find where in your app he can invite his friends. You record all clicks, and time and etc until he finds it.

This test is served as "partners quest" on free mobile games. The gamer has to complete your "use quest" in order to continue playing that pool game. You pay the game producer a small fee and charge from the mobile apps developers that want to test their designs.

You may give the gamers more in-game bonus if he allows you to record his voice and face (and pay the game producer a little bit more for this feautre).

<comment><USER34> These guys are doing it for a whole app. Maybe get in touch with them. [http://techcrunch.com/2014/04/11/app-io-turns-ios-apps- into-...](http://techcrunch.com/2014/04/11/app-io-turns-ios-apps-into- playable-mobile-ads/)

</comment></comment><comment><USER35> A subscription service for open source projects.

As a company I would pay you monthly and get access to bug and features development for all the open source dependencies that I am using. The more I pay the more things I can get done in a month. If a feature is too big for my budget I can accumulate month to month value on a ticket or get other companies to participate.

<comment><USER36> I'm not taking a side (really!), but there's a lot to be said for keeping open source projects strong on their own without injecting cash. Cash coming in creates a disincentive to develop without cash and promotes a reliance on paid services rather than a mentality of contributing back. Also, when it comes to many projects, the organization that offers services around them has a negative incentive to contribute clear, quality code.

<comment><USER4> > ...there's a lot to be said for keeping open source projects strong on their > own without injecting cash.

Money is already all over the open-source world. Many smaller projects will not involve it much, but it matters in the larger ones. E.g., much of the code contributed to the Linux kernel comes from people who write it as part of their jobs. That means that feature additions & bug fixes in Linux will be largely those that matter to (say) Red Hat. This idea offers a way to get work _I_ want done prioritized without needing to know how to do it myself.

It also offers the possibility of software development midway between the start-up model that groups like YC and Kickstarter are pushing, and the no- money-involved-ever model. Surely somewhere between the two we might find something workable.

> Also, when it comes to many projects, the organization that offers services > around them has a negative incentive to contribute clear, quality code.

A good point. I don't have an answer for that one.

</comment></comment></comment><comment><USER37> I want a batch notification service. Every 15/30/60/90/configurable minutes (or on request), the service would ping all my communication channels and give me a summary on a page or to a mobile app. I don't have notifications for email/social media because I don't want the interruption but, during downtime, I find myself checking through all the different services I use to see what's outstanding. I don't need the app to interact with these services, just ping via API and return what's "unread."

I tried to use IFTTT to build something workable but the key is getting notifications all at once for everything when I want them, not duplicated notifications when they come in.

I'm willing and able to work on this with someone if anyone wants this problem solved (PHP, JS).

<comment><USER38> I wrote something to bundle "alerts". It was a node application which would receive updates via HTTP-posts.

From there they would be injected into a redis queue, and fanned out to email (daily), a simple HTTP web-page, and xmpp.

It wasn't hard to setup the core. The hard part was pushing notifications into it. I suspect you might have the same problem. Writing a deamon to stream twitter and POST items matching a regexp, etc. Good luck integrating with facebook too!

Most of the pieces are out there, and joining them up isn't hard. But .. it didn't work out as well as expected just because of the integration aspects. That said I have a semi-working system pinging me via XMPP when new blogs are posted, etc.

<comment><USER37> I don't know that batching the alerts would solve the problem, I want to be able to ping these services to determine unread counts at that point in time. I'm, of course, just assuming that these are available via API from the services I use.

</comment></comment></comment><comment><USER39> Blackbox web security SAAS.

There are some services out there that will scan you for vulnerabilities, but I have yet to find a really slick way to integrate security "for free" into your own servers/services.

This would mean at minimum:

1\. apt-get install X. Automatically decent kernel/network/firewall configuration occurs, removes cleartext passwords from ssh and changes the port, etc etc. This is just a base starting line.

2\. malicious user detector. Probably cooperating with an API within ruby/jvm/python/php/whatever is a mixpanel-like way I can define custom events and possible milestone-firewalls. E.g. this is a new user sign up, here are the relevant fields & ip. Or here's a comment on an image from user X with IP Y. Rather than having to figure out if we're likely being abused outsource that decision to the service & have it help you block the evil-doer.

3\. APIs to help with usernames/passwords, setting up TLS & perfect forward secrecy, etc. That is to say, give me patterns I can use that every app has even with some level of customization.

4\. Have built in DDOS protection, particularly for resource starvation attacks that might be more app-specific (request X took Y>Z time, and it's being repeated endlessly).

I understand that security is complicated, ideally should have full time staff, every app/service is different, ya yada. Except when you're starting out you don't have these kinds of resources and something like this could get one quite far, not to mention be able to see much of the internet and what's happening across clients (like gmail with spam) and thus have an advantage over you. It seems like a giant hole in the world of app development and most people are terrible at security when it comes down to doing anything more than firewall + ssh keys + bcrypt user passwords.

<comment><USER40> So this would be similar to Impermium (now acquired by Google) meets Sift Science meets Cloud Flare - have you checked them out?

I have thought of building such a security as a service for websites for sometime. My PhD thesis was on building a reverse proxy server (kind of like nginx) to detect attackers (via machine learning) and starve them of CPU/network resources disproportionately (using admission control + WFQ) during a DDoS attack. After that I've spent a decade building systems to detect cyber security threats, click fraud, Twitter spammers, etc.

What do you think is lacking in existing security as a service offerings that prompted your post? Would love to chat more.

Think "trails" from V Bush's "As we may think" article, implemented so we can collaborate. As users start bookmarking things in their own trail, the app works out what other trails are similar and suggests you merge your researching efforts.

<comment><USER42> Google wave was great for almost this, actually, minus the matching / merging part! Sad to see it go.

<comment><USER41> Yes. I think this idea is almost in many things but you need to give the user the structure to both read and contribute to a thread of research.

</comment></comment></comment><comment><USER43> A pay-to-post/view social discussion site.

Reddit starts out cool, then slowly becomes 'dumber' (discussion-focused articles turn into quick reaction images) as it becomes more and more popular.

Hacker News avoids this by purposefully not trying to be as popular as Reddit -- UI remains minimal, tries to stay out of search engines' ways, etc.

But, in this way, HN is discussion focused through obscurity. What if you filtered out dumb crap by making it a cost to the user for posting? In that way, the user would _have_ to really care about what h/she's posting about before h/she posts it. I.E.: thought-provoking discussion and not cheap images.

That way, you can mass market and accept huge gains in popularity while being sure that the people who are posting/voting on the stuff care enough to pay for it. Want cheap (often not even funny) images? Go to Reddit.

The best posters get compensated with the money that the voters paid. This creates a network of "I pay to post and I pay to vote but I get money from posting which incentivizes me to post but I only get paid if I get voted on a lot which means I'll want to encourage voting which means I'll have to vote a lot myself" : the voters and content contributors conflate in one genius network of money movement.

It still wouldn't ever get as big as Reddit, simply because people don't like direct payment for services on the Internet. But it'd be an effective way to get a bunch of smart, dedicated people who would kill for thought-provoking discussion on the Internet, and also pay them for just that.

<comment><USER44> How do you handle users gaming the system for profit?

I was thinking up various ways to introduce money to our communication systems to incentivize certain behaviors. But not from the modern Facetwitter perspective of a site that wastes your life by addicting you. The true measure should be the correctness of the content and money should pay for that.

First a system where you have to pay to post and if you post is confirmed as not spam or abuse, then you get the money back. Otherwise the site takes your money. Should be a negligible amount. Mostly a way to make spam expensive and compensate for moderation, but of course a site can abuse a user this way as well.

If a user posts some profound story/comment and others want to compensate him directly with an easy UI, they can add a monetary amount to their upvote. But there is little guarantee that the amount will be significant or the money will arrive promptly. Users should be able to undo money sent for well sounding but ultimately wrong info. This is to discourage participation driven by points and monetary rewards.

If participation and content creation is driven by money even more than it is now, there will be a few new legitimate sources with useful information but the vast majority will be content farms. To discourage this "points" or "money" should accumulate, BUT should not be paid out for years until the accuracy of this content is confirmed by the passage of time, peer review, etc. If mistakes are found, all readers should be notified of corrections. There should be penalties for releasing misleading or mislabeled information (like tech blog posts that are really advertising but pretend not to be. You should pay to advertise and pay more for advertising what turns out to be crap after peer review.)

A site should take its share for moderating content well and working on rules that incentivize useful content/services and penalize attention seeking of little utility.

It's hard to predict effects of various new incentives. But a site should work on modifying the rules until desired results are reached. Users should not stray from normal behavior to satisfy some quick and dirty addicting point systems. If that means limiting participation to select trained users, releasing information to larger audiences only after it has been discussed by relevant experts (so no shocking attention grabbing studies are released) then so be it.

Resuscitate Xoopit, a much much better gmail search. Have you ever wondered why gmail search sucks when its parent company is the supposedly the best search engine in the world. Xoopit was a nifty addon that mine your inbox and 1) organize every file and links it found, and 2) gave you a search feature at least 10 times better than the gmail option.

I would pay once for the first tool, and monthly for the second product.

<comment><USER46> "Email Link" : Something you want to save for reading later? Pocket and other services do the exact same thing, that is, they save links for reading later, and you can email it to yourself too.

And you don't need to pay for it.

There are plenty of "List of frontend development tools" or "list of git tools".

I want a site where users can build lists, share them, vote on them, categorize the content and update it with the new tools.

alternativeto.net is a partial attempt at doing that but it doesn't take a systems thinking approach

<comment><USER48> I've always wanted something like this to. Only, I suspect that lists are only one possible form of information that needs to be organized. I also think users should be able to shape trees (and maybe others).

Maybe you encourage vistors to click on everything they agree with and thereby learn which users contributions are seen to be the most valuable. Users with the most valuable contributions could be rewarded with more ability to shape the tree or list...

<comment><USER47> List would supported nested lists i.e it would be a tree

In terms of rewards or monetization, it would be possible to gamify contributions ala stackexchange and rely on affiliate links for commercials tools and perhaps even share the revenues with the top contributors or offer them options on what to do with the money

I was helping someone set up her android phone for podcasts and noticed how problematic the whole process is. First, the android apps aren't very good. More problematic is the process of getting a feed into it. Sometimes searching by name works. Often it doesn't. Getting from podcast's website to the app is a problem. Discovery is also quite poor.

For example I have have mine set to keep only latest 2 podcasts pershow, auto download on wifi, and auto delete those I've listened to. It's a well built app worth way above $3.99. Don't bother buying other podcast apps or even show apps like This American Life.

How about a URL Shortener that caches the page at the time the shortened URL is created?

Then, when the short url is used, the service attempts to reach the site, if it fails, automatically inform user & redirect them to cached page.

Or, the service can attempt to reach the page periodically (once/ couple minutes), if fails, redirect all users to cached page until next attempt in a couple minutes. This period can be based on number of users clicking on the url. Once the link is no longer very popular, the service will have a fairly long time between attempts.

<comment><USER52> The free Coral CDN ([http://www.coralcdn.org/](http://www.coralcdn.org/)) already does something like this. It caches the link the first time it is visited. But rather than redirecting you to the original page if it's up, it always show its own mirror of the page (on its nyud.net domain).

One could say something like the "location" field in chat programs deals with this, but hardly anyone keeps that current. In the past, I would blast a Facebook status of my new location and hope that people would notice - <USER2> sort of worked, but it was by no means perfect (and I have since deactivated my account there)

The reports would simply show- how much time I spent on what segment (Productive work/ General Browsing).

A chrome extension/app would be a good starting point - personally I do not use other browsers unless absolutely required.

Further I would also like it to automatically classify and show what kind of content I spend time browsing - like "Entrepreneurship / Programming / Nuclear fusion / Space Travel / ... "

If anybody wants to try it - let me know. I can dedicate a very small amount of time on this.

According to Vice/other sources, it's becoming increasingly popular for gangs to communicate publicly via Twitter and other social media sources. It's an interesting NLP problem because Twitter language is crazy and an interesting "computational social science" problem because it could actually help communities. You could partner with (or sell it to) municipal police departments.

The entire OpenStreetMap dataset is 23 GiB with moderate compression. With some optimization/truncuation the whole world should fit comfortably on most phones.

This is very useful, for the times you're lost with a slow connection, no connection, in a foreign country, or with roaming charges.

* A better credit rating system. The current one kinda sucks, no offense to Transunion, Experian, and whatever that other one is. Just because Joe Schmoe was unemployed 18 months ago and struggled to pay the rent, much less pay the bills, does not mean that Joe Schmoe is currently unable to do so. A creditor can claim a debt from Sally Schmoe, and Sally has little recourse in fighting it -- it's ridiculously complicated to combat something you know nothing about. Usually she winds up just paying the bogus bill to get it off her credit report. The whole thing is a racket.

* A better job candidate review systems. Companies spend a lot of money hiring recruiters, but recruiters just spam the crap out of people and then send all the resumes in anyway. What if there were an app that could pre-qualify candidates? Cut out the middle man -- death to recruiters! (figuratively, of course)

* A good, interactive environment for remote calls with kids (or anyone, I guess). I'm thinking Skype meets building blocks. Maybe we have to wait for Oculus Rift, or maybe Kinect is enough to get started. For example, I live in San Francisco, and my niece lives in Atlanta. I don't want her to not know who I am. I want to be able to Facetime/Skype with her -- and as she grows, I want to be able to interact with her, play games with her on a shared screen, teach her new words and phrases, and so on. My girlfriend's nephews live 8 hours away, and her parents live even farther away. The nephews are growing up quick, and we Facetime as much as possible, but even so, it's limited to just talking and pointing at a screen. You can make this better. As grandparents, aunts, and uncles increasingly get used to technology, they will want more ways to interact with their young family members without breaking the bank on plane tickets to visit -- and they'll spend money to do it! A small subscription and microtransactions (new games/books!) would be infinitely cheaper than flying across the country. Someone make this happen.

I'm not really sure if that's legit or not, but I've read several articles about teams creating watches that can run and/or charge off body heat.

One of the biggest parts of the hearing aid is the part that holds the battery. If you could somehow eliminate that, then hearing aids could be super, super, super tiny, in addition to saving me the hassle of having to buy batteries -- or worse, being in a situation (like the middle of a date) where it dies on me and I don't have a replacement!

I'm sure this is a pipe dream, but it would be awesome if someone could make it happen.

There are lots of things you could do, from watching all of the videos since the one you last viewed, to a better way of editing playlists than the current one.

They should also make a way to preview videos, like hovering over the image of the video and you see a 15 or 30 second preview that you can choose from a part of the video. There should also be a way to instantly switch from computer to phone/tablet, just like chromecast.

If you just open up YouTube right now you can see how many links you can choose, there is way too much clutter on the front page.

YouTube has a great opportunity to distinguish themselves from traditional media, but they keep making design choices that prevent this. YouTube has become the leading video service because they created a platform that differentiated from traditional media, yet the current trajectory doesn't fit with that.

Chad Hurley is also one of the few notable alumni from the Technology Student Association, an organization I am a current member of that has not benefited from the recent increase in STEM funding.

</comment></comment><comment><USER90> I don't expect this would be a company, but rather more of an open source project. I have been thinking about this for a while, so I'll throw it up to see if there is any interest. I would really like someone to create a website full of information and resources for first time startup employees regarding stock options.

It would be great if there was a calculator which would allow you to experiment with different liquidity outcomes given your existing/proposed stock options.

For example, you would be asked to enter the total number of outstanding shares, the number of shares you have now, the number of shares you are entitled to, your vesting schedule, if you have any acceleration upon change of control or other scenarios and if so how much, whether you have preferred vs common shares, liquidation preferences (if any), etc.

Once you enter all of the information that you have, the calculator can estimate how much you stand to make in certain scenarios. You could answer "How much does the company need to be bought for in order for my options to be worth $X?" or "If the company sold for $Y amount, how much would my options be worth?".

If certain pieces of information were not entered into the calculator, then it could show error messages and link to additional resources explaining why that particular number is so important.

I realize that the calculator would likely not be exact because of missing information and the complexities of each particular company's structure. However, I think in many cases it could be surprisingly accurate. The most important thing is that it be used as a tool to introduce important concepts and terms which new startup employees should research and understand.

<comment><USER59> Contrary to your statement about how it could be __surprisingly accurate__, it would in fact be the opposite. There is no accurate way to build a calculator to show different liquidity outcomes because there are way too many unknown variables if you understand how stocks actually work in a given company. Everything would have to be a complete guess in the dark for the employee punching in those numbers making it near impossible to get anything accurate, particularly early stage.

<comment><USER91> On the contrary, "How much does the company need to be worth for my options to be worth $X?" can be answered with a _surprising_ amount of accuracy. Because isn't that basic mathematics with the variables "Exercise Price" and "Stock price"? I am talking about value of options for EXERCISE here, not selling them off. The selling part is what gets a little complicated, but we have ways to price them as well so a calculator for that could be built as well.

I'm driving to a coffee place, great, but then it's 10min turning around the place looking for parking. Ideally it should drive me in real-time to a place where I can park.

<comment><USER74> I was thinking the other day about this. They have cars that can park themselves already. I think Audi has been advertising them. They obviously use some sort of sensor to detect empty parking spaces. What would be brilliant is if they did two things:

1) Used GPS coordinates to figure out if you are in a high-demand area for parking and, if so:

2) Passively scan for parking spots as you drive by, then upload them to the cloud.

You don't actually have to be looking for a parking spot -- but your driving by an empty one could help someone else.

A more YC-focused idea is to design a small device that does exactly that for _any_ car and is as simple as dropping something onto your antenna or sticking it on a passenger-side window.

It seems like the tools for discovering and rating charities are well developed, but the tools for allowing them to collaborate and provide help are non existent.

This would allow a more holistic approach to giving; A single parent who gets tuition assistance might also benefit from free babysitting or help with meals, which are probably provided by two different groups. Social workers would be able to assemble a variety of different forms of help for each recipient, and the program could automatically suggest donor/recipient matches.

</comment></comment></comment><comment><USER107> It could be useful to have a site where researchers could post their failed attempts at solving difficult problems, a sort of "Journal of Failed Ideas".

I saw this suggested in a reddit thread a while back, might've been the Bill Gates AMA, but the comment was something to the effect of, "What if cancer researchers could post things they've tried in some central location, without the overhead of publishing papers in a journal?"

This wouldn't have to only apply to researchers. I had a similar idea while ago for a site where motorcyclists could post how they got into an accident so that others could avoid the same fate, like an informal NTSB-style accident report.

<comment><USER108> The problem is the incentives are all wrong for reporting negative outcomes - basically you get no benefit, but it cost you time.

What would work would be to pay each researcher for every negative result they published and more importantly why the idea failed. Often the failure is caused by something minor that the researcher overlooked when doing the experiment initially - I have saved many a project in the pub, by just chatting informally with people about the problems they are having.

* Someway to re-introduce photos into cabins' visitors books.

In Norway, all cabins have their own visitors book. Until the mid-'00s these books were filled with physical photographs. With digital cameras, the images in these books have disappeared, and there has not yet been invented a way of attaching digital albums to each trip/chapter/page. (Social networks doesn't do the work, as a lot of people who aren't connected to each other read these books.)

The people who writes about their cabin trip need somewhere to upload the images from their stay, and the people reading the book need someway to see these photos.

I'm afraid that if I do a website and it is breached, all the users would suffer. Therefore I'd rather someone made a service that kept all sensitive user info, like email and password, separate from my webapp. The only way to access it would be via api over a unique user ID. Then I could worry about doing the website instead of about security.

EDIT: Also, one teamt would fix bugs such as heartbleed, and everyone using the service would be secure. It would eliminate the security risks of leaving an old side project running.

1\. Would be labor intensive, but: a site (blog?) that talks to people/experts from various industries, quizzing them about problems they face in their daily jobs. Some of these might be solvable by software. It doesn't need to be too detailed, but it would help if it is totally outside of the _usual_ tech stuff - the quirkier the better.

People can pick something from the blog, instead of building yet another project management app.

2\. A website that asks a series of questions (skillsets, weather preferences, languages spoken, food preferences, age, educational qualifications etc) and suggests countries/cities to move to. Should also take into consideration special visa privileges (canada-us, nz-aus etc). It would be quite tough to keep the data fresh, for an app like this. but this would be immensely useful, and it can be monetized too. Even if done narrowly (ex: only for software people), it would still be very useful.

Idea is why don't we have an mobile/web application which will list out nearby restaurants and users who posted that they want a company to share their lunch bill. With this advantage is that they can try out different dishes and still with lesser expense as you would share with your stranger partner.

To be more specific about the application: 1)Any one wants to share their lunch bill, they open the application and check the near by hotels. 2)If anyone has posted already that they need a partner to share lunch, you could join them (probably their taste also mentioned in the app) 3)If you don't find any one who's open for sharing, you can post one.

This will work out for people those who travel, single, students,group of strangers.,

Apologies, I should have explained myself better.

Being aimed at people with only their own wits to guide them, their knowledge is likely to be patchy. So filling in knowledge, even basic things such as mentioned by yourself would be included.

<comment><USER158> Sure. Here's the first specific issue I've encountered.

I want to find out how to install a deadbolt on my door which only has a keyed knob. I'd like to install one on two of the three exterior doors. The doors are steel, and I with my zero-knowledge of home improvement, don't know how, or if I even could, drill holes through them. Because I needed to change the locks right away, I just bought some new doorknobs and changed them all out.

Of course, I didn't realize I got locks that have different keys for each of the three exterior doors. Ugh. They will only have to be temporary.

I _really_ don't want to replace the door from messing up a drilling job. I've spent 20 minutes now researching and only now I'm kind of confident that have the resources to figure out exactly what I need to do.

The best one-stop-shop site for learning I've found is doityourself.com. It has basically all the features I'm looking for - howtos, forums, user- submitted projects, but the site is bloated(just open up dev tools and watch the ocean of requests on pageload). The site is also not responsive.

I already feel overwhelmed at how much I'm going to have to learn to keep my house in good shape for my family. The lack of a good web resource is frustrating. I'm considering attacking this problem as well. Feel free to email me.

1) An API framework with an ORM of sorts around the existing graph dbs ( it could be Gremlin based ).

This would allow queries on levels of nodes ( tutorials -> { python | ruby } -> { django | flask } , etc. Another dimension would be { beginner | intermediate | hard }. An important search dimension might be the popularity of the curator (submitter), the upvoters and downvoters, etc. The API would allow RESTful retrieval of nodes, and based on permissions granted to the user allow operations such as voting, modification, creation and deletion. Wikipedia like data could be public domain, but the API itself could be self- hosted on private servers allowing for enterprises to have their own internal wiki of sorts.

Licensing should allow extension of the API if needed for premium revenue models that might allow users to create 'n' relationships on a server that is a kind of bookmarks, can keep private graphs, clones/forks of existing graphs/sub-graphs with annotations, etc. Or contributors may contribute code to extend features on the open source platform as well.

2) A web/mobile UI that would leverage this API and create the UX around searching, for example, a) cross-indexing wikipedia and storing as graphs and allow different search algorithms to be built. b) a knowledge graph of maths ( similar to the ones at khan academy ) and linking in the URLs / videos based on dimensions such as target age, content length, language, pre-requisites, etc.

I for one back this request with a passion! Best series ever. What were they thinking canning this?

</comment></comment><comment><USER168> A DOM aggregator/filter browser plugin.

Let's say I'm looking for a room on AirBNB. The filter they have on their website isn't specific enough: if I want to find a room that's $32 or less and that has at least 20 reviews, I have to use my eyeballs to filter all the < $35 results. What's more, there are many pages of results, making side-by-side comparison difficult. My idea is to create a browser plugin that harvests each element of a particular HTML class on a webpage (".search-result"), filters it based on the contents of some of the child classes (".listing-price < 32", ". listing-review-count > 20"), and puts all the results in a single window, probably using CSS copied from the original page. All I'd have to do in the AirBNB case is plug in the classes and comparators listed above and quickly cycle through each page of the listings with "gather mode" turned on. I'd then have all my preferred results in one place. Perhaps the plugin could even allow you to identify your classes by simply pointing and clicking on the desired nodes, much like the inspector in developer tools!

Ultimately, with this idea as the basis, I think you could make a great Automator-style tool that streamlines your research. Is there some information that's missing in the search results? Make it follow the links and filter the full listing descriptions! Looking for listings with specific kinds of owners? Do some keyword matching on each profile! Want a map of all your filtered locations? Gather the GPS data and display it in a beautiful native map interface! (Maybe you could even interface with external services like Wolfram or Yelp: crime statistics, nearby restaurant reviews, Amazon ratings?) Kind of like a web scraper, but with a very user-friendly UI specifically tailored for filtering and aggregating search results. You wouldn't have to keep 100 tabs open anymore when you're doing research: everything would be saved and synced in a handy Evernote-like interface.

I've run into this problem frequently enough with comparison shopping that I think there's value in this idea. I'm not really all that inclined to make it unless I can make some money, but I made a little Javascript rough draft script that can filter a webpage's DOM if you manually enter all the classes and comparators and copy/paste it into the dev console. A lot more work than the browser plugin I described, but still very useful for my purposes.

<comment><USER168> That looks really promising! I will have to look into that.

The previous discussion on HN[1] has a few more interesting leads. A lot of people there are advocating writing their own scraper, but the point of this sort of idea is to allow you to get going in just a few seconds, without ever having to poke around in the dev tools, debug custom scripts, or even look at the HTML source. If you're going to be doing research for an hour, spending half an hour on writing your own scraper just feels like a waste.

So I decided to make it right. I used chrome developer tools's edit html feature... I edited the html and behold the grammar error was gone. I read the paragraph again with pure delight. I love technology.

Idea Generated: There are lots of blog posts out there that have good content, but sometimes they are not written well or grammar errors exists because of lack of proof-reading.

What if there was a web-app where readers can correct blog posts or articles. Of course, it needs the approval of the author. There might be a 'Correct me if I have grammar errors' button of some sort somewhere in the post.

The editor is not allowed to edit the meaning of the content, only the typos and/or grammar errors, which of course needs the approval of the author. It's like github for blog posts and articles.
