An evolvable code artificial life engine that I wrote while in college-- its quite sophisticated and still runs:

https://github.com/adamierymenko/archis

Nanopond is another, an attempt to condense the above into its smallest possible essence and in C. A number of folks have ported it to other languages, and I got one e-mail a while back that they were using it for burn-in testing on some supercomputing hardware at Lawrence Livermore:

Java n-dimensional array library-- also works but haven't touched in a long time:

https://github.com/adamierymenko/hyperdrive

Used Google Maps, FlightAware and the USGS database of named places to provide Google Street View for flights.

Essentially, you could look up any flight in real time and get a map showing points-of-interest viewable (ideally) from the plane. I had everything working but then racked up about $200 in FlightAware API calls so I shut it down.

Honestly though, I got sick of go and sick of writing the library. I'm not much of a fanboy of anything, but ya generics. They woulda been nice. I operated on the blank interface type a lot, and it's honestly just annoying doing all those case statements checking what type it is when I coulda just wrote a polymorphic method for the types I support. I always read on here though that you gotta adapt to the go style.. so maybe there's some more elegant way to go about it than I was, but meh, not worth diving into for me personally.

Now I'm writing my first Scala library and I looove Scala! I'm taking this library very seriously and expect to have a Show HN within a month or two.

I had issues to run cucumber tests. There are many tests and they are slow. Some tests are randomly fail affected by the state of other tests. That's why I made baleen. It runs cucumber tests parallel and independently on Docker containers. Unfortunately, I couldn't use in real env because my tests are dependent on Oracle database and running oracle database in each container are slow which defeats the first goal of baleen. Here is also a post about how it works. http://kimh.github.io/blog/en/docker/running-docker-containe...

What licence is the code under? I would like to take some sections of it.

Editabled, the editable pixel editor: https://dl.dropboxusercontent.com/u/138485812/editabled/full... (live demo) Broken on chrome, because they effed around with web workers. So I need to look at that. It's basically a JS-based rendering engine. If you look closely, you'll note the lines you draw aren't antiailiased, which lines drawn with the canvas2d API are. Fast compositing engine using typed arrays. Async rendering using Web Workers. Infinite canvas, you can scroll with the arrow keys and no matter how large it gets it never seems to slow down. ^_^ Potential, might have the time to pick it up again, but that was before I was properly employed. Very technical atm, but I might get back around to it in a bit. :/ That's about it here. There's also http://ddr0.github.io/cube%20trains/index.html, my attempt at an indie game, which is downloadable from Github. I am no marketer, so I only sold a handful of units. (ie, I can count sales on one hand) Also available on http://ddr.itch.io/cube-trains. There's more potential here, and I think it's pretty easy to extend. The game comes with an editor, so you can make and share your own maps. Sort of cute, really pushing my graphics abilities, and ended up with it's own pathing algorithm which I never did add the people for. It was scheduled for v2, but I was pretty tired of the project by then.

Eh, hardly an impressive folder compared to some of this stuff (nanopond), but oh well.

It's quite playable (though save/load don't work), and surprisingly hard to beat the AI. Sadly, it seems completely useless on a mobile device since it relies on the mousewheel for zooming. [Edit: mousewheels are things people used to scroll and zoom with back in 2009 before they realized they could just pinch the screen.]

Give it a big galaxy with lots of planets then let the various AIs fight each other at full speed.

Also, long ago I used to download files which were too large to be transfered to another PC over the network, some even didn't fit the USB thumb drives I had at hand; so I created this desktop app which splits large files into smaller volumes, which you can copy around easier and then use the same program to join the pieces and get the original file.

I was very happy to receive requests from other people who contributed with traslations to the UI messages.

It's written in Python (not very elegantly) and I haven't touched it in ages:

https://github.com/dfuenzalida/gtkfilesplitter

Finally, another small project: a plugin for the gEdit text editor which shows the git branch of the file being edited (if any). It should still work in the most recent GNOME desktops, but I do most of my editing in other text editors now.

Slice Station https://play.google.com/store/apps/details?id=com.slicestati... - abandoned Android music exploration app when our provider fell through. Not going to lie, this is pretty outdated given the foundation was built in 2010 on Android 1.6. But the exploration concept is still very good and worth trying to revive.

PyKRP Engine https://github.com/keerthik/KRPEngine - A python game engine dependent on pygame targeted at rapid prototyping 2D game mechanics. Provides easy menus, game loop, screen setup, etc. Abandoned when I broke up with Python 3 years ago.

I have a couple of Unity game projects lying around on hard drives, someday I'll push them to github and share next time this Ask HN comes around...

Sockets https://github.com/navarr/Sockets - Wrapper around PHP socket classes to turn them OOP, and I don't mean like some crappy HelperClasses, I mean treating sockets as objects you read and write from.

TwCLI https://github.com/navarr/TwCLI - A browser-based twitter "command line interface." Abandoned long ago, written in PHP and fairly terrible. Not at all newish work.

Hanafuda https://github.com/navarr/Hanafuda - Hanafuda libraries in PHP for maintaining a game state for a variation of Hanafuda and Koi-Koi. Don't think I got very far

PHP-Shogi https://github.com/navarr/PHP-Shogi - Library for handling a game of Shogi in PHP (maintaining rules, enforcing game state)

A small bit of python built to use the (hopefully true/reliable/trustworthy) hardware RNG in most cryptographic tokens/smartcards, to feed the Linux kernel entropy pool (which /dev/random pulls from, etc). I built it to replace an older, (now completely unusable) C program for the same purpose called CardRand, which is mentioned and linked to in the project. TokenTools uses standard PKCS#11 libraries (even binary, proprietary ones) to handle talking to smartcards, so it should be broadly compatible and non-fragile, whereas CardRand wasn't.

TokenTools isn't strictly "abandoned", and it does work pretty well I've been using it for a long time but I haven't touched the code in a while and it could probably use some testing with different cards and PKCS#11 libraries.

https://github.com/infincia/NetRNG

A client/server python system that uses the (again, hopefully trustworthy) hardware RNG found on inexpensive ARM boards like the Raspberry PI and Beaglebone to provide entropy samples to other machines on a LAN, and again feed them into the Linux kernel entropy pool there. I've been using this one for a long time too. However there are 2 branches, one based on ZeroMQ which I use, and the other which directly uses sockets. The socket branch has some issues directly related to the socket communication, which is why I'm not using it myself but I'd like to go that route and drop ZeroMQ for a variety of reasons.

I have a bit of an obsession with RNGs :)

https://github.com/kennethrapp/journalist - general purpose livejournal client (PHP), created so I could write my own blog client for my website and crosspost, but I no longer really care about livejournal so meh.

https://github.com/kennethrapp/embedbug - page crawler and attempt at an open souce embed.ly-ish plugin (PHP) - it does work but every project i've started which uses it has been abandoned because I don't have the time.

I've currently got a PHP/Laravel clone of Hacker News which kind of sort of works but not well enough that I'd want to push it to github unless people really want to dig into that. I barely work on it anymore and there's no documentation all.

Also i'm working on some c++ and C# projects, including a todo list based on my final project this semester. I'll probably either post it in a week or two or just forget it ever happened.

And this (https://gist.github.com/kennethrapp/0ef17d2145f2a6e38cca) was going to be a general purpose Hacker News userscript. I got as far as getting the callbacks to work before just giving up and using other people's already working scripts. Someone might find it useful.

http://github.com/MDamien/publicdb : Create datasets and have an (ugly) API. The goal was for everyone to create a database on almost anything (recipes, photos, party, budgeting). Later I discovered that it's what firebase/parse are doing. But I'm happy with my solution because you don't even have to use JSON to store you things and the interface is really simple.

http://kioto.io/ : Would be cool if any group could have an anonymous "suggestion box" ? Maybe! So I made this. But at the end I'm gonna do better a online discussion system based on ideas from reddit/discourse/disqus.

https://github.com/MDamien/GifMyLife : Just an app to take of photo of you at regular intervals and then it makes a timelapse GIF of that (good to see how your face and your mood evolves with time).

Really nice idea from OP, people are posting really interesting stuff

For that kind of work it doesn't need to be perfect. The output doesn't even need to compile first time. It's just a way to save time by starting with a scaffold and refactoring, rather than writing from scratch.

Not sure if I'll get around to forking it anytime soon, but I've bookmarked it for future reference, as I could see myself using it in the not-too-distant future.

There's a few obvious things that it doesn't support (e.g., chunked encoding...), that make it hard to recommend as a general purpose solution. But for serving files and debug data it's OK, and it does promise never to call your callback on another thread.

https://github.com/atrus6/python-music

Composing MIDIs using n-grams and python. The music created is VERY monotonous and boring.

https://github.com/worldsproject/android-jigsaw-puzzle-libra...

I swear I'm going to add on to this soon, but this library cuts given images into jigsaw puzzles, which you can then put together. Was eventually going to be a multiplayer game called "Puzzles with Friends"

Swapped work to this:

https://github.com/andrewchambers/cc A C preprocessor and a C parser, both partially complete.

All in Go. Want to finish this, but sometimes go a week or two with no work.

Various mips emulators:

https://github.com/andrewchambers/cmips (boots linux, I intended to compile it with emscripten)

https://github.com/andrewchambers/luamips (Not as complete as cmips, i intended for it to boot inside gmod)

A social content creation tool with cartography features.

A document consist of sections, sections contain paragraphs. One single paragraph may have many instances across different documents.

Users can repost paragraphs, createdby someone else. When the original author updates the paragraph then that update propagates to all the instances.

Similar, one section may simultaneously exists in different documents. Any changes in that section are visible in all that documents.

Forced anonymity but you can track individual contributor in the scope of a single discussion (visible user ids started from 1 for each thread).

https://github.com/senotrusov/redis-call - A Ruby library to access Redis using Hiredis takes care of thread-aware connections, handy API for keys' names construction, transactions and queues.

The idea spawned from people wanting to take over other people's side projects (completed, abandoned, whatever in-between).

We've been running it for awhile, (check out in PH - http://www.producthunt.com/posts/sideprojectors)

LottoLane: http://lottolane.com A lottery pool management tool. Built this to use at work. We used it a few times and it works well. I just never marketed it that much.

While it doesn't use Hadoop, you can run it standalone to process datasets using the Pig model.

https://github.com/shabinesh/Tabject

it's a service written in node.js that you can deploy to run your own URL-shortening service

it works fine, but I wrote it my second semester in college, so the code is kinda bad, needs a ton of refactoring

A very simple and crude dungeon crawl made when I was learning Clojure (the code is very bad as I was learning the language).

Source code analyzer for C that optimizes the usage of data structures in your code.

I got tired of Mojang fucking the protocol over and over.

Like Goodreads, Shelfari etc... but emphasis on shelf and following other's shelves.

Microservice written in Go that provides user management, authentication, and authorization.

Not abandoned but just slow development due to other priorities.
