https://github.com/Lazin/Akumuli - embedded time-series database. I'm trying to achieve very high write throughput - about 1M updates per second. The key idea here is to store data in large sorted files and search them with interpolation search with fall-back to binary search in some cases. I expect this method to be much more efficient than b-tree or LSM-tree for time-series data.

#42http://gameofworlds.net a voxel video game with custom everything.
It's cool because you can change everything, even program terrain and blocks distribution over the world.

#45Still heavily under development:
http://charsheets.herokuapp.com/
Pathfinder d&d based character sheet manager. I got annoyed with the static and excel based offerings out there so I created my own. Currently I view it as near fully featured and want to make it work with more traffic than Heroku can support, but I have no idea how (web-hosting for these types of sites seems expensive as all heck).
Anywho, it was also a way for me to learn flask, bootstrap and knockout.

#46https://retred.org is a repository of (right now historical) events. There wasn't a good place where you can view and (soon will be able to add/edit) historical facts, not to mention cutting it up in various ways to see how things relate.
this is such a great idea! it would be great to be able to choose a series of events (e.g. d-day or the Beatles tour in 1967) and see the progression of events across a map in the order they happened. or to get a cross section of all the events that happened on a given date around the world or in a chosen area. edit: after exploring further I realise some of this is already possible. again, a great idea!
Thanks - as you say, if you search for a thing you will see the events with lines between them showing the progression of events in chronological order.
You can use the time bar on the top to alter the date range, and there are "favourite" era's selectable at the drop down down the bottom.

#47Smarter NPC. Not an actual game yet, but i started out trying to create a generic AI system for NPC, because i really want to play games like that. So i decided to contribute to this dream by making an open-source AI module for NPC to help game developers create amazing games.
My idea is to make a Goal-based system. Each NPC would have a set of goals, and would weigh in available actions as to how closer it would take them to their goals. I decided to start of with something simple like "maximize gold" so the NPC would take actions that resulted in most gold increase. i figured if i did it right, the NPC would themsleves figure out paths in action-trees that would let them make more gold. for example, figuring out that making wooden stuff out of logs is more profitable than selling raw wood. Or that if you can afford it, hiring people to make the wooden stuff (like a business/company) is more profitable overall than doing it yourself (cuz of multi-threading, opportunity cost, overall path weight, etc).
So it would be cool to see NPC picking out roles themselves, forming in-game societies and behavin in line with their goals. heck maybe someone can make a game that would involve using people's goals to influence them

#48I am helping people to realize that life could be much more than this meaningless competition for so-called "success" fueled by greed, pride and exhibitionist consumption.)
I am high altitude trekking instructor and cultural guide for Himalayan region (Tibet, Nepal, North India). I provide no-nonsense introduction to Buddhist and Hindu philosophy, ancient, "primitive" ritual-based religions, tribal culture and traditions.
I am helping ex-addicts, like myself, to almost undo the accumulated damage and to rebuild themselves from within, by educating them in Eastern tradition of self-knowledge (our nature without religious nonsense).
I am also advocating "old-school" understanding-based approach to programming, as opposed to copy-paste-based modern coding.

#49https://appenlight.com - Unique application exception and performance monitoring that saves time.
Why it's great?
Combining performance metrics + powerful exception reports and pure logging into single package makes optimization and debugging way easier than having X solutions in separate places. Works especially well for complex applications.
One of cool features is that we offer access to all data like SQL queries even in free plan - unlike New Relic and others.

#50http://spout.co -- We're trying to make building finance apps alot less scary for the average developer. To be honest I see no reason why the average person can't add p2p payments into their app or why an accounting software should have to wait years before adding bank syncing. We're making all of this do-able in a weekend or even at a hackathon. We just launched to a few live customers last week and already we have…
I am interested. Do you guys cover european banks? FYI, your signup for a private beta makes it very hard to click send. there is like 1 pixel on the send-button that actually triggers the action.
Thanks for the feedback, you can also hit enter, but I'll push a fix to change that too! :)
Oh, and yes! we're starting to cover some European banks and have plans for further European and asian expansion soon too.
