Game of Life

During the congress AK told me about the Game of Life
which imho is pretty interresting and makes alot of fun to watch the shapes that will arise in such a cellular automate.
A friend of him implemented a very complex software to do such simmulations in which you can create your own rules etc.
But the basic rules are just that the bit (animal or whatever) will die if less than 2 bits are in the environment because of lonelyness, more than 3 bits because of crowding
and a dead bit will come to life if exactly 3 bits are in the environment.
What I didn't know and I think most of the people don't know is that the famous hacker emblem
is a so-called glider which is just one example of a form of life which can be simulated in the game of life. The glider is special because of its
construction it will glide from one corner to the other.
So here is my small implementation for the glider (you have to edit source if you want to see something else):

ii becomes more and more popular, people realize how flexible this program can be. Of course others hate it 
Matthias Kopferman gave me the hint to write to the in-files with vim and now I use it with multitail to track the out-files and vim to write to the in-files.
The hint Matthias gave was to define mappings to write to different channels.
So I start my vim in the server directory and use mappings like:
map w1 :.w >> #ii/in
map w2 :.w >> #wmii/in
to write to the channels. Very cool.
There is also some guy who is creating a php based irc "client" which uses ii in the background.
http://yogan.meinungsverstaerker.de/phpii/index.php
And this is exactly what I mean with flexibility, you can nearly do everything which is IRC related with ii.
So if people say its not usable cause its too minimalistic they don't realize that it wouldn't be very difficult to write
for example a GTK-frontend. It only has to handle 2 sorts of files.

Today I installed videodb its a nice PHP written software which manages your film collection in a webinterface and a MySQL database.
The cool thing is that you have not to edit this all manual because it supports lookups for different sites like for example
the Internet Movie Database so you just have to click on the film and it will be added
with length, title, year, producer, content and as cool addon a picture of the film bill.
You also have the possibility to manage users, mark films as borrowed an search for movies.
This is a really nice peace of software by the author of the Dokuwiki wiki engine and its easy to install.
This image is copied from the videodb website of course I don't run my web browser under WIndows.

Its possible, we implemented a fractal generator in Opal.
Source code available at http://user.cs.tu-berlin.de/~nion/fractal/
UPDATE: this link no longer works the university punished me because of making this public.
Nice to see that opal can also be used to do something and not only to promote the TU-Berlin
