I have made some new toys that might be of interest:
Instead of waiting for the next database dump and downloading the whole thing, you can now get a XML dump for all articles in a category and its subcategories:
http://tools.wikimedia.de/~magnus/cat2xml.php?category=History_Version_0.5_a...
Sadly, the toolserver is somewhat broken for use on en, so it doesn't even know "Category:Wikipedia Version 0.5", but that is someone else's problem (since ages, I might add). So until this is fixed, you can't get the complete article texts for 0.5 in one swift motion, but then! ;-)
I have also found a web server (Server2Go) which runs directly from CD (or the main directory of any drive, including USB sticks). I have managed to integrate MediaWiki into it. While a MySQL variant is available, I went for a new MediaWiki database type supporting plain-text files (read-only at the moment). Back to the roots, I guess ;-)
Anyway, I have created what I hope is a standalone, zero-install "History Wikipedia 0.5" bundle, currently consisting of a pityful 19 articles. This was done by converting the above mentioned custom-XML-dump into plain-text articles using a script from my wiki2xml toy.
Categories don't work, and I was too lazy to set up interlanguage links. No images either.
Still interested? Try http://tools.wikimedia.de/~magnus/history05.zip (23MB)
Best to burn the whole thing to a CD, as it /has/ to be in the root directory. I *did* mention that it's currently Windows-only, right?
