I built and launched Geocoda (https://geocoda.com), which lets developers location-enable their applications. Initial features include geocoding and a spatial database.

Thanks to the first round of feedback we got on HN, and to those who have already checked it out!

Working literally every waking hour (22 hour+ coding sessions) for two weeks, I've created a replacement for our WinPE-based Windows repair CDs [1] in Linux, in anticipation of Microsoft's non-renewal of all WinPE licensing agreements to 3rd parties, and made them fit on an ISO that (GUI desktop environment, all kinds drivers and binary blobs, web browser, partition editor, custom repair tools, and all) is only 40MiB. CDs will (hopefully, DV) fix any and all boot-related issues, attempt to repair registry, and perform various sanity checks to get your PC booting once more for Windows XP - 7.

Now for the testing phase! (anyone interested in trying it out, drop me an email mqudsi@neosmart.net and I'll send you a copy for free)

I completely rebuilt http://refer.ly and learned just enough about the backend part to configure the entire box myself on EC2 (yay!). 350 people in the beta, and sending out the next batch of invites tonight. Yay!

I built an in-memory NoSQL index (not a database) for answering subset inclusion queries, i.e. "find me all the Items with {Feature1, Feature2, Feature3}". It also supports queries by category, and by color.

It's vastly faster than SQL for this purpose.

I say it's not a database because it isn't even a Key-Value store. It's just a key-store - you query it for the keys, and retrieve the values from somewhere else (e.g. postgres).

I built srctree (http://srctree.net/). In short, it aims to be a pastebin + git + canvas mix. An example of usage: http://srctree.net/3Q-1

It still needs a lot of work to become usable, but I am already happy I got this far!
