A URL shortening service (as a slightly non-trivial exercise in Erlang).
hint: use base36 to convert numeric IDs to short strings. That's how I do it on http://gifexplode.com
You can use base64 if you're happy with case sensitive URLs.

#112My Django hosting service. I looked at Heroku and thought, "I want that for Python." Yesterday, I got most of the http request path finished. There is some node.js work left, and I still need to do some more work on Varnish. I'm hoping to get to the Postgresql stuff next week, then on to the website and API...
You have me sold, please give me the heads up when you're done. I've been looking for this for a long time.

#113I'm working on text classification. I have a decent classifier that's especially suited to author identification. I can think of a few good uses for it; the first one I'm trying to commercialize is academic anti-cheating.
That sounds fascinating. How did you come up with the algorithms to use?

I've been thinking of trying to write a machine learning app to do just that. Any hints?
I didn't implement the machine learning algorithms for myself, because there are some really good packages out there and I know I don't have the smarts to better them. Keep in mind that I didn't really have any success: There seem to be two main ML packages, Weka and Orange. I personally preferred Orange, it has a nice graph-based UI for linking various components together; when you've figured that out it can script…
This sounds like an awesome project!
Why did re-implementing the dissertation for greyhounds not work? Was the dissertation flawed?
If you're putting this much effort into it, why not stop by a horse racing track a few times and pick up some domain knowledge? Maybe you could even talk to race horse owners, jockeys, breeders?
I wonder if you could turn this into a product for breeders? Or maybe for people buying/selling race horses? Or people hiring Jockeys, or even marketing an offshoot of this to the gamblers? Just some wild thoughts.

#115Adding support for JSON-RPC in Pylons.
Eventually this will lead to integrating pyjamas as an alternative to templating for pure-AJAX applications. This will mean adding a setuptools plugin for compiling the pyjamas client before packaging the application, creating a paster template for generating the project structure, and extending the test framework to support functional tests.
It might mean creating yet another framework built on pylons, but I'm hoping it will get folded into Pylons proper so that I don't have to maintain a separate project.

Is that...significant indentation in Perl? Will you marry me?
Well, actually it's kind of like an unholy Python/Tcl mutant thing, since the one-word tag determines the parsing of its line and children - but yes, significant indentation using a Perl filter.

#120Something like the Django admin feature but for MS Sql Server and more generic; to sell to companies. I figure a lot of companies have databases for internal purposes but don't have programmers to make CRUD apps for them.
I'm still not sure how to locate potential customers or how much to charge. Any advice on that?
