Portable Computing

I really have no right to talk about this subject, as I have never actually done it. I thought it might make for a good hypothetical post, though, especially since I don’t have any other good ideas right now. What can I say, it’s on my mind. That’s because of where I was when I wrote this. I’m thinking about portable computing right now because I keep everything on my hard drive. Well, stuff that isn’t email or associated with a Web service. Applications and stuff all live on my computer. When I go somewhere else, I can’t get at…

XKCD Roundup: My Favorite XKCD Comics

I’ve selected a few exceptionally good xkcd comic strips and embedded them here. I find them all particularly amusing, over and above the normal strips. The tooltips have been preserved as well. I advise you to read them; the comics sometimes don’t make sense without.

And you can fix the annoying title truncation in Firefox using this nice extension. Centrifugal Force This is one of those things that just hits my funny bone…

MySQL Upgrade, with a Small Issue

I upgraded MySQL on my computer a week or two ago, and had an almost flawless install. The only problem was I had to go back to the old my.ini. No biggie; just rename the files.

When I saw all the errors caused by the new configuration file, I thought I would lose all my stuff. Good thing I found a fix. I wish…

MediaWiki Upgrade, but One Thing Didn’t Work

I upgraded MediaWiki from 1.9.3 to 1.10.0 on May 10. I like the new features. Only problem: page restrictions were moved from a column in the page table to a separate table in the upgrade. The upgrade script, though this will be fixed in a later release, made `wikidb.page_restrictions.pr_expiry` equal to NULL instead of “infinity”. Problem? Shouldn’t be ordinarily, but Special:Protectedpages didn’t work; the entries from pre-1.10.0 didn’t display. I just changed them all manually using phpMyAdmin, but it’s fortunate I have a small wiki. Maybe I should learn SQL to cope with possible future errors…
