I'm building a distributed network, called Aether, that allows people to create and participate in reddit-like forums anonymously. It's fully encrypted. Take a look at http://www.getaether.net It's cool because: * It's anonymous. The posts jump from one node to another with no author information except a nickname. They cannot be traced back to the origin. * It's encrypted with TLS_RSA_WITH_AES_256_CBC_SHA cipher suit…

I was thinking about doing something similar. One of the things I wanted to incorporate was an reputation ability (beyond just blocking). It would be similar to a referral engine in Netflix or Amazon.

So, I'm user A. I mark user B as a high-value poster. User B marks user C as a high-value poster. When I run across a post by user C, I see they have a good reputation. If many people I ranked as high-value, also ranked user C as high-value, then I see user C as having a very high reputation. The same, in reverse, for low-value posters.

A book that explains the core ideas of neural networks and deep learning. Cool because: * The book incorporates lots of running code for readers to explore and extend. * The book's philosophy is to go deep into the core concepts of deep learning, not to superficially cover a long laundry list of ideas. This gives readers a solid foundation to build on, and makes understanding other material much easier. * Deep learni…

A high performance, affordable personal airplane: http://www.skycraftairplanes.com It's extremely fuel efficient, can fly 575 miles on a tank, cruises at 118 mph, and comes standard with really nice instrumentation including GPS, collision avoidance, synthetic flight, and an auxiliary input for your iPod. They sell for $55k. Here's the HN post I made a few months ago: https://news.ycombinator.com/item?id=5826062

One of the coolest and most unexpected things I've seen on HN! Excited to see what you guys do in the future - a two seater at a similar price-point would be real game changer.

DrumLog.com (http://www.drumlog.com) - Analytics for your practice sessions. It's a web app for drummers to track what and how much they are practicing.

It's Cool because:

* Creates analytics from an offline activity

* Built with Backbone.js, Node.js (Express.js), hosted on Heroku, and uses Parse to store data. (all great free services)

* Is being actively used by over 100 drummers who have logged over 3200 practice sessions in about 3 months.

Soundslice ( http://www.soundslice.com/ ) -- animated guitar tabs / sheet music. Demo: http://www.soundslice.com/tabs/5680/bohemian-rhapsody-for-so... It's cool because: * The state of the art in guitar tabs is horrible ASCII crap (example: http://tabs.ultimate-guitar.com/e/eagles/hotel_california_ta... ). Soundslice is a 1000x improvement. * It solves a key problem for musicians, which is: when you're learning a new…

This reminded me of Miso Media (http://techcrunch.com/2011/09/14/miso-media-raises-another-2...), though at a glance I see that they're pretty different.

I appreciate that your app is web-based, personally. And to have done it all in canvas is crazy impressive-- especially considering the slickness of the interface. Kudos!

Robot Audio (http://robotaudio.com) - An online DAW (Digital Audio Workstation). The app itself is not ready yet, but you can play with the synthesis engine on the signup page.

It's cool because:

* You can now make something like Ableton Live or Garage Band directly in the browser.

* You will have all of you work and assets available from any computer and won't need to worry about license keys.

* It will be much easier to share and collaborate with others.

* It will be affordable (between $5 - $20/mo) as opposed to $600 - $1200 for Ableton Live.

> Currently working on an open source implementation of Minecraft Nice. Are you aiming to implement a thread-safe plugin API, perchance? The current problem with bukkit (and with vanilla minecraft server, of course) afaik is that whenever a plugin needs access to global state, it uses an API that does not do any locks of any sort; which means that usually, whenever one needs to e.g. write to global state, one dumps t…

It's just a library, so it doesn't handle plugins. However, the library is thread-safe, and the server [1] I wrote on top of the library supports plugins and is also thread safe. For anything dependent on a specific thread, there's generally a queue to push things into. [1] https://github.com/SirCmpwn/PartyCraft

That sounds like a very nice and thought-through architecture/design.

What's your current status / how far away are you from a more or less complete beta (e.g. in regards to the minecraft client) (if you don't mind me asking)?

A friend and I are developing a new fast, space-efficient (read: probabilistic) key-value store. We're using it for some computational biology applications.

It's cool because: * It scales to really large data sets: We store ~10 billion keys in memory on a single, not-too-ridiculous machine, and the design supports sharding trivially * It's fast: we have a lot of optimization still, but can do ~1M lookups/sec (O(1) lookups) * It's a data structure! (Which as non-formal-CS people we find fun)

Would be very interested to hear other applications that people would find the above attributes useful for!
