Python Concurrency

Attended David Beazley’s python concurrency class over the weekend in Chicago. We were schooled on the horrific nature of the GIL, coroutines, generators, threads, processes, etc., etc. – a grand tour of nearly everything you can do to make multiple things happen at once. It was an excellent class and I would encourage anyone who wants to learn more about concurrency with python to attend future classes.

Mr. Beazley also has a very good collection of slides on coroutines/generators probably best described on the oubiwann blog but I will list here as well.

From the class a concurrency mailing list has sprung up on google groups: http://groups.google.com/group/python-concurrency

Mr. Eden has a great post on accessing mssql from linux.

I had to add one package (unixodbc-dev) to get things working so I ended up with the following:

sudo aptitude install unixodbc unixodbc-dev freetds-dev tdsodbc python-dev


Once this was done the usual “python setup.py install” no longer ended in tears. He also included instruction on editing the odbcinst.ini file.
