Long Night of Porting SimpleParse

So once again I tried to port SimpleParse to Python 3.x. After a half-hour or so of playing with doing a complete rewrite in Cython I realized that scope creep was going to kill me, so I went back to the C-coded mxTextTools and started working out how to port that.

First step up ...

Every Test

I hate little bugs that shouldn't be.
Every test it passes.
I test every corner of the case.
Every test it passes.
Pulling logs, pushing scripts.
Every test it passes.
Spelunking through the code.
Every test it passes.
Screaming at the IDE.
Still
Every test it passes.

Django Migration Migration Strategy

We embed Django in devices. There are 100s to 1000s of each device scattered around the world, each controlled by someone who may decide (for perfectly valid reasons) not to update one of those machines for years. Until now, we've used South migrations to allow a machine of any vintage to update to current ...

Did I just create another Inotify Interface?

This is one of those moments where you finish something and think "why did I go and do that?"

I recall an hour or two ago thinking "you know, wouldn't it be nice to have inotify integrated into Twisted", and that lead me into reading the Inotify man-page, which lead to me thinking "oh ...

PyOpenGL 3.1.1a1 is out

This is basically just a bug-fix release, though it has some more extensions wrapped/available, as it uses an updated Khronos xml ...

Type Declarations for Python 2.7

So there's a big flamey thread over on python-list about the Python 3.x type-annotation. Thing is, I can't say the annotations seem all *that* important to the behaviour (static type checking): Consider this Python 2.7 decorator-set:

def _func_annotation_for(func):
    """Retrieve the function annotation for a given function or create it"""
    current ...

NIST Sphere Format

I downloaded the TEDLIUM speech corpus last night, and this afternoon I poked around in it and said grr. It uses a NIST Sphere format which is basically a plain-text header followed by encoded samples... it's a WAV file, but with far fewer useful tools. Oh well, thinks I, I'll just transcode the ...

More Reading and Waiting in Neural Networks

I continued my long reading in Neural Networks today. I'm now setup with Theano, and working through the DeepLearning.net tutorials... but wow, I was not prepared for the (lack of) speed. Hours and hours to train a network (I don't have an nVidia GPU, so everything is being done on the CPU ...
