There is a nice bit of Javascript code here: http://alexgorbatchev.com/wiki/SyntaxHighlighter This package allows uses css to display pretty source code on a webpage. It supports a lot of languages, but is missing a lot of common ones too.
If you are using Blogger (or somewhere else where you can't upload files). You can hot link the the scripts and css at http://alexgorbatchev.com/pub/sh/ which is up 99% of the time.

kdbom.tryDBconnect
I put a factory function for kdbom.db instances in kdbom.kdbom (previously I had it in viroinfo).
It automatically checks localhost,3306 for the database after checking at the specified sites.... good if clients are not on the same private subnet the the server is on.

Google + Python + LLVM
There has been talk of targeting python to LLVM before (PyPy). Google is jumping in with the Unladen Swallow Project, hoping for performance multiples in the 3-5x range.
Update:
More from PyPy's author.

GPL Harmful (the heresy of ESR)
Open source software and hacker God Eric S. Raymond (ESR) told the Long Island Linux Club (LILUG) that the GPL does more harm than good. Needless to say the GNU herd didn't want to hear it.

Old Snooping Methods are New Again
I guess this has been in the works for a while, but now it's out in the open. Remember: just because you are paranoid, that doesn't mean they aren't after you.

What people really think about God
It is interesting to see the hate people have for people who have the audacity to believe something they do not. Sunnite <=> Shi'ite; Christian <=> Pastafarian.

PEP 289 -- Generator Expressions
Everyone that learned python from me, probably doesn't know these exist. So take note:
kewler than list comprehension: generator expressions (!)

finaly factored out PickleableObject
uses my nonclobbering file opener: safeOFW
I've been meaning to move this from a class that Peter wrote it in to originally at my request. It's quite nice to have it globally available.
class PickleableObject(object):
"""Generic pickleable class
"""
def save(self,filename,clobber=False):
"""given an object, e.g. a taxon dictionary,
pickle it into the specified filename
Set clobber = True to allow overwriting of the
output file"""
import cPickle
f = safeOFW(filename,clobber=clobber,append=False)
cPickle.dump(self,f)
f.close()
@classmethod
def restore(cls,filename):
"""given a filename, return an object containing the
pickled data in that file"""
import cPickle
f = open(filename,'rb')
obj = cPickle.load(f)
return obj

Words that nerds use that I hate
distro - "distribution" please
tarball - "tar file" (the fact that it is gzipped, will be obvious to any that care)
architected - the word you are looking for is "designed" n.b. actual architects do not use this word to describe their activities.
sequel - Do you mean "S"-"Q"-"L"? (./ers you know the 'sequel' form is M$ spawn, right?)
