Have moved SquareMap into LaunchPad and done a bit of work on making it more wxPythonic and adaptable.  I've also made it handle "empty" space better, so that if you have time spent in local for a given parent it shows up as empty space in the parent.  That's important in RunSnakeRun because you want ...

Have RunSnakeRun imported into LaunchPad now.  I've also implemented a version that uses an enhanced SquareMap so that you can see the hierarchic relationships in the data.  Because of the way cProfile works, you don't see "deep" relationships, that is, while I know that a calls c for 50% of the time, and that c ...

Just built a little square map implementation in wxPython.  Eventually will be integrating it into RunSnakeRun to let you see a graphical breakdown of the hotspots in your profile (as you do in KCacheGrind, but this should run easily on any of the major platforms because of wxPython).  I think I'll want to tweak the ...

I used to do ridiculous amounts of Javascript for Holodesk, so I *should* have immediately twigged to this, but it's been 8 years and I've managed to block this particular silliness out.  Say you have a reusable (Dojo) widget where you need to access "this" in a callback.  The callback function will have "this" bound ...

Have been spending a lot of quality time with Dojo this weekend, and it's making me think about abstractions again.  The pattern seems to repeat itself again and again; you dive into a deep pool of someone else's abstractions, you spend days working out all the little undocumented assumptions and missing pieces, eventually you get ...

Looks like two of my talk proposals for PyCon have been accepted.  One is an intermediate/advanced talk porting your code to OpenGL 3.x, the other an introductory presentation on Profiling/optimization.  Should be fun :) .

Back when I was doing the next-generation (now many generations old) Multi-User Technology (MUTech) for Holodesk I thought it was really cool that there was no "server", it was all just peers where any given object could be hosted on any machine, and the system would let you set up (potentially one-way) proxies on any ...

Here are my rough notes from PyGTA's programming mantra's discussion this evening:

In the face of ambiguity, refuse the temptation to guess.
   Have a vision before you start coding.
   Know your task.
   Know your client.
   Ignore the impossibility behind the curtain.
Your clients don't know what they want.
   Charge by the hour.
   Play around with ...

Ran into this problem on Friday at a client site and just couldn't find a Python library that did everything I needed wrt providing login to TurboGears and properly uploading a file to a controller in the TurboGears application.  Bothered me that there was no easy way to do this (seems like it should be ...

Was looking into mitigating some of the slowdown from the recent fix, mainly be rewriting this little function:

@classmethod
def from_param( cls, instance, typeCode=None ):
    try:
        pointer = cls.dataPointer( instance )
    except TypeError, err:
        array = cls.asArray( instance, typeCode )
        pp = ctypes.c_void_p( cls.dataPointer( array ) )
        pp._temporary_array_ = (array,)
        return pp
    else:
        return ctypes.c_void_p( ...
