Do you have one or two services or applications that constantly hang or eat far too much CPU? Would you like to tell them they annoy you in a more forceful way than just kill?
Now you can, with the hammer time patch for the psmisc tools.
This patch will add the --with-a-hammer option to killall, so you can feel vindicated when these annoying processes get terminated with extreme prejudice.
In the past few years I've set up and used MediaWikis for various open source related activities, for instance linux.conf.au 2008 and Linux Users of Victoria. Both of these would be prime targets for wikispam if anyone could anonymously edit pages on them, so edit privileges are limited to registered users only.
I'd been thinking about getting mobile broadband for a while, but up until recently all options were pretty expensive. You had to pay through the nose for fairly small traffic allowances and since these were all plans, you pay even if you don't use.
