Range arithmetic in Python
The XML 1.0 and 1.1 standards define some ranges of Unicode code points which are valid, and some "compatibility characters" which should not be used. CDS Invenio (a FOSS CMS; update: sorry, the link is dead) already has some code to clean up text to remove invalid characters, but it doesn't remove the compatibility characters. Using the existing code for HTML 4.01 made the W3C Markup Validation Service complain, so I wanted to exclude the compatibility character ranges from the valid ranges, and get the most concise hexadecimal ranges corresponding to the resulting set to plug into a Python regular expression. Here's the
resultingsloppy and ugly code (I'll post updated code and/or a link to the source repository if this is included at some point): -
Firefox profile folder cleanup script

Unit testing Python + MySQLdb warnings
There seems to be several methods out there, based on elevating warnings to errors using
warnings.simplefilter(Update: sorry, the link is dead). Here's another method, based on recording warnings in a variable (Update: sorry, the link is dead), and checking that the last one is aMySQLdb.Warning. Hopefully to be integrated in INSPIRE. -

Add namespace prefix to XML tags in Vim
It's not perfect, but it works with tags that contain just a-z and dashes (the
\([a-z-]*\)part)::%s/<\(\/\?\)\([a-z-]*\)\(\s\|>\)/<\1namespace:\2\3/gc

Moving from France to Switzerland
There's quite a bit of paperwork involved when moving from France to Switzerland. This is a rough account of what happened after the housing agent called to say we had been selected to get an apartment. It might be useful to anyone considering, or in the process of, moving to Switzerland from abroad. However, it's by no means a complete account, and you should always check with authorities or others who have done the same if in doubt.

Back on track!
Finally, after 7 months downtime the blog is up and running again. I guess five nines is out for the next millennium or so.
l0b0.netis no more, but filterous.com (Update: Unfortunately this site is long gone. Sorry for the inconvenience!) should soon provide the only really useful thing from the old website: del.icio.us bookmark filtering.
