Qsnake 0.9.11 released

[Ondrej Certik]

Hi,

I just released Qsnake 0.9.11. Qsnake is a source distribution for
scientific computing, with unified Python interface.

Here is how to try it:

wget --no-check-certificate
https://github.com/downloads/qsnake/qsnake/qsnake-0.9.11.tar
tar xf qsnake-0.9.11.tar
cd qsnake-0.9.11
./qsnake -b

And then you run it by:

./qsnake

You can also try the preliminary GUI in the browser by launching the
lab() inside qsnake. So far only linux is supported (I only tested
several versions of Ubuntu so far). Please report any bugs, or if it
fails to build.

Qsnake 0.9.11 successfully built in my 64 bit lucid ubuntu laptop. The
GUI is nice but I could not figure out how I can evaluate the codes.
When I clicked ctrl+c to close the gui I got the following:

In [4]: lab()
Starting Web GUI: Open your web browser at http://localhost:8888/
Press CTRL+C to kill it

Thanks a lot for testing it!

You need to enable "websockets" in Firefox. If you use the latest
Chrome, it should work out of the box.

Interesting. For me, I get the following if I press ctrl-C:

You can try the latest version by following the instructions in the
"Development Version":

https://github.com/qsnake/qsnake/blob/master/README.rst

then you'll get all the latest fixes.
