Antlr eclipse: to plug on not to plug

This is just a reminder for me.

This commercial soft looks very much of appealing, but I bet it will not write grammars instead of me, so computer still needs a human.

Following such simple logic, why not to use a free plugin. This antlrv3ide works for me.

Of course, one can always specify antlr as an external tool.

PS after a short test run antlrv3ide does the job. I have grammars highlighting editor, and I can generate the code by button click.

Wikipedia corpus

While there have been a lot of speculation around Web 2.0 and Semantic Web manifestations of wikipedia like nature, Wikipedia itself is a great corpus to do information retrieval and run semantic experiments on (just saying the obvious).

Never the less this is well understood by such startups as

http://www.powerset.com/ a tool with fancy UI design to do NL "search"

and

http://www.freebase.com/ one of the promising social networks for "I like" information. Not really another facebook or digg.

Both companies do a lot of retrieving for further compilations just like DJs like to play with Beethoven's pieces.

Real entities

Today I have wasted several hours for the concept outline of my new open source startup. The idea behind is so simple, based on all well known components. But as a join vision I think that is a new simple way of designing quick light-weight database applications. Now the most challenging task is, of course, not the idea of atomic hashes itself, which is trivial, but the implementation of the query language for the project. Once you have a version control like svn content management for data maintain, realentities library is a solution worth to consider.

jQuery Kid

Pretty cool for a kid. Even I was able to understand everything, and it's a little bad I already knew this.

This proves how easy it is to taught someone programming and stuff (As I once said, one can teach even a primate or a smart dog). Google obviously benefits from spending all that crazy money for the "get the brain" approach. What they do should be done in any educational model of a progressive institution, especially in math or natural. One should really enjoy the process and have fun.

Q: What is eduction (of a brain)?

A: Education is a constant dialog with your brain (or technically, I think, a specialist will say between both of head brain's hemispheres). If your brain is interested in something that means it is ready to learn this something, that means there are enough connections in your neural network, that are active enough, to make the final conclusion - the final connection. So if you are about to study something, do it with passion and understanding, thus building and exploding a better network for a
better understanding. And finally, the proper understanding is actually a conclusion that is often your own discovery of a particular small fact, that you have just come up with and you are able to see it very clearly by repeatedly accessing a result from the same neural circuit which allows you to compute that fact. So, if you are about to grade results of your own eduction, then grade it by measuring not applicative skills of knowledge, but the discovering skills with help of that knowledge as well as all the small discoveries themselves.

counting automaton problem

As I've promised, here is the problem inspired by the riddle from the Sophus book. I don't want to cite the text from the page. Briefly, speaking it may be a very simple problem with a simple solution or a problem without solution at all.

Mathesis.ru

Again, quite a remarkable set of old and rare mathematical and natural science books, published in Russian, mostly before and after the revolution of 1917. The period is exactly form 1904 till 1925.

"Games with matches" is the book that had actually driven my attention to the site http://mathesis.ru/book/tromgolt2

I think I will put some of the problems from the book online.
