Slight cheat, since I've just stopped working on it (released yesterday):

iPhone app that lets you view photos from a bunch of different online sources.

We're doing the official site for the presidential debate commission. This includes a flash app (and extensive backend server infrastructure) that allows you to record your views on a variety of topics, compare them to the candidates, as well as the rest of the USA.

You can drill down into some fairly detailed stats, but I think it's fair to say that so far MySpace's demographic isn't a representative slice of the USA.

We'll also be carrying the live streams, and hosting a shitload of post-debate clips.

The tech is kind of interesting... we're dynamically generating AS3 code from erb templates on the backend, compiling it, and serving up SWFs which are dynamically linked into the runtime.

Our Akamai cache bill is going to be hilarious.

Could you elaborate some more on that? It seems...unusual (but interesting, yes)

So, there's a core "player" app, which contains all the important stuff, but no UI. The UI for each "page" is retrieved by hitting a merb controller, which reads an XML file, runs it through erb, pipes the result to the AS3 compiler, and serves up the resulting SWF. The SWF is loaded into the main application, and the page is displayed. (Naturally, there's some hashing/caching going on so the compilation only occurs if the source changes). The XML files are "sort of" like mxml, in that they contain primarily layout information as well as snippets of AS3 code, but it's based around our own system - which allows us to do a lot more cool stuff. The nice thing is that when you're working on a single page, recompilation is really fast - our last app had about 100K lines of code, and changing the tiniest thing took forever.

Cool... hope the video player doesn't crash.

this seems pretty sexy. I'll do my best to help crash your precious snowflake system tonight (i.e. using it and futzing around during the debates)

Good god man... you're not supposed to use it! That'll break it for sure.

Sweet, now I know where I'm going to watch the debate tonight

I should warn you that there are going to be live questions/votes pushed out to the player. If you are easily annoyed by something scrolling up from the bottom of the window asking you if you think abortion rocks or not, then best to get the feed elsewhere. Hopefully they won't be too invasive though.

Edit: Phew. Well, that's over and my code didn't kill anybody. I consider that a win.

Los Angeles online food delivery/carryout website - 500+ restaurants and counting! Built by myself and two other ex-videogame industry folks over the past few months.

It's a blend of merb, couchdb, ruby, and some rather esoteric javascript systems on the client-side - all running on EC2. Still technically "beta", but now open to the public.

This is a multithreaded echo server running with an epoll loop on each thread.

How does the multi-threading figure in? I take it you're not creating a thread per connection - otherwise you wouldn't be that much better off than just using blocking sockets.

There are a fixed number of threads (probably the number of cores or twice that number) and connections are assigned randomly to a thread.

This is completely going to bottleneck on the network connection, even if you ran it on one CPU, of course.

Cool cool.
