Practical, yes. I am going back to 5 year old notes on instruction scheduling and using the same code and algorithms to deliver targeted advertisement on the net.

As a former compiler junkie that sounds interesting, can you elaborate?

[Edit: Sorry man, this is my bread and butter. Excitement got into my head and I barfed out a few things I should have left out.

I hope I don't come across as rude and evasive if I said "sorry, can't give any more info; just think hard about it" :-) ]

My project is InfoML (http://infoml.org/), a proposed standard for storing "chunks" of (human-readable) text and annotating it with various useful metadata, including tags and bibliographic information. I hope there will eventually be a community of developers who will find InfoML useful and will build a variety of software tools for manipulating data stored in this format.

Zak, by classifier I hope you mean "categorizer". i.e. given a text and a list of categories, return which categories the text belongs to, along with a confidence number. If so, I say chase that thought a bit. You might save me from actually messing with NLP.

Yes, I do. The usage is essentially identical to the Bayesian probability classifiers commonly used for spam detection. I compared several of the classifiers available in CRM114 and found hyperspace to be the most accurate as well as being much faster when checking a large number of categories.

Amazing. This is pretty cool :-)

The thing is 100% statistical right? It doesn't know anything about the grammar of a natural language (say, English.) right?

It's entirely non-statistical. It works by measuring the Hamming distance between samples using features consisting of single tokens, sequences of tokens and sequences of tokens with gaps. For example:

The

The quick

The quick brown

The quick ... jumped

would all be features of the input "The quick brown fox jumped over the lazy dog".

It doesn't know anything about grammar, though as a performance optimization it might be useful to limit the length of features to detectable sentence boundaries. I intend to make that behavior optional. More information here: http://crm114.sourceforge.net/docs/KNN_Hyperspace_Filters/KN...

I'm actually looking for a new name for my project, so maybe someone here will have a good idea? It's a framework for writing, running and analyzing simulations. It could take any kind of simulation: Physics, game theory, epidemic spread, electronics, whatever. It's in Python. This is where it currently lives: http://github.com/cool-RR/physicsthing/tree/master (Keep in mind it's still a very young project) The readme…

pysicsss (I dunno. Something trying to blend python, physics, simulation, and the sssss sound a snake makes).

Wouldn't it be better to modify an existing, popular language to support this feature?

It would be better, but I want to do some cool things that I'm not sure if I can support in an existing language. One thing is automatically preserving state across a reload. This is really hard if I allow the programmer to store state any way that they want- I can't tell which things I should preserve. So the language forces the programmer to declare their stateful things in a special way. Another thing is introspec…

Did you check out Smalltalk?

Unity is a game engine that uses Mono as its scripting languages. You can recompile on the fly (you frequently play the game in-IDE during development). All public variables are exposed to its inspector and survive this recompilation. It's a great engine in general: http://unity3d.com

Mono is not a scripting language. The Unity Scripting language is similar to ECMAscript, but is not standard and does not have comprehensive documentation. It is true that you can interact with the mono / .net 2.0 system libraries.

... and you have about a 1/3 chance of it crashing if you are using the recompile on the fly as you edit.. command p, alt+tab, save, alt+tab, command p...

Working on a messaging client that integrates Twitter and GTalk... And I mean really integrates. The end user doesn't know the difference between IM and twitter but the context in which the user sends a message decides the service to use. It's C# and WPF. http://github.com/jcbozonier/alloy/tree/master

That would be a really useful thing. Keep us posted when that goes live.

I think a microformat schema or schemas would be more beneficial for this kind of data.
