I wanted to code up a single-form application for updating/editing the PyGTA events.  Since it runs on Vex and I didn't want to bother them with setting up per-user WSGIs or TurboGears for me (they do give me the space free, after all), I went with bald CGI.

Wow.

I've written very large CGI-only systems ...

We had a lively PyGTA this evening on the topic of concurrency.  After which I put out a call for those who are interested in helping setup and teach (low-cost) courses on Python.

Our first course looks to be an Introduction to Django, likely on a Saturday in early November, taught by a consultant who ...

This post from the numpy list shows you how to turn a ctypes c_void_p into a numpy array.  The glMapBuffer() function maps your currently-bound array into a void * which you can access directly... combining the two:

def map_buffer( vbo, access=GL_READ_WRITE ):
    """Map the given buffer into a numpy array..."""
    func = ctypes.pythonapi.PyBuffer_FromMemory
    func.restype = ...

Toying yet more with compressing rdiff-backup repositories with hard-linking.  Turns out there's already someone who's done it.  My script for hard-link finding is different than the (packaged) one he's using, but it seems to have the same basic idea (I use filecmp, though, rather than reading the files myself, and I don't check owner/group/mode ...

Continuing to toy with rdiff-backup.  There's enough areas that you *don't* want to back up (or rather, don't need to, such as icon and font caches) that you wind up with some pretty hideous command-line operations if you go that route, but this post is about another need, namely the need to "compress" the storage ...

Can't sleep, so thought I might do some work getting a better backup system built for our machines.  I really like rdiff-backup so far, it's got the "rewind to any time" functionality I'd like, along with reasonable query features and fairly simple operation, so this:

rdiff-backup --exclude-if-present .svn --exclude-if-present .bzr --exclude-if-present CVS

pretty much does ...

As regular readers will know, I've been working (slowly) on a rewrite of my BIS Thesis in Design Epistemology.  The original thesis was huge, covering way more material than anyone should attempt to cover in one thesis, and as a result it was rather cursory in its coverage of most of the areas on which ...

Have been seeing weirdly trivial blog-post spam lately.  Someone will post a single-line comment that is entirely generic, no real content, just a bland "nice post" or "thanks for the article" where the user's URL is a link to what looks like a SEO page.

Turns out that there's a set of sites that "markets" ...

It seems like all of the projects I host on SourceForge are no longer easy-installable.  The only ones that can install are the ones that have been uploaded to PyPI, and then only the versions on PyPI install (i.e. a later version on SF doesn't install or prevent an earlier version from installing).  I'm guessing ...

We're going with a round-table discussion at PyGTA this evening.  How do *you* deal with exceptional conditions in your code?  7:10pm at Linux Caffe.
