Hobo Lobo of Hamelin

Hobo Lobo of Hamelin is worth looking at even if just for the novelty of how the story and artwork are digitally presented (something to do with a ‘parallaxer’). But, I'd much rather let the creator do the talking: Read More »

I need a Nanny for Google Chrome

I just installed Nanny for Google Chrome, which, like LeechBlock for Firefox, should help me to recoup some of the time that is now actively being stolen by YouLube and FaceLook. If I'm too weak on my own to push back technology to its proper servile place, then I might as well use technology to do some of the pushing for me. You're a tool, you damn computer, nothing more than that! Read More »

Making Linux less dumb about failed DNS servers

Whenever one of the servers in /etc/resolv.conf is unreachable, Linux/glibc/whatever isn't smart enough not to retry it for a while. This results in a lot of services becoming unavailable, because a lot of them do reverse lookups on all incoming connections (like SSH), which will hang for the time-out of the first DNS server query.

Getting munin to run every 10 minutes

Munin is kind of inefficient and on my P4 2Ghz, it running every 5 minutes is too often, and the munin processes keep dying because locks already exist. You can't increase the munin-cron script to 10 minute intervals, because then rrdtool will generate gaps. Read More »

Adding a clock in screen to avoid your ssh’s from being killed

The world is filled with stupid routers, which kill all connections that have no activity for a while (even a very short while). I keep loosing my SSH sessions because of this. To fix it, I added a clock in my GNU screen bar: Read More »

Shrinking/compressing a MediaWiki database

As of late, I haven't had a lot of time to chase after spammers, so – despite of anti-spam captchas and everything – a couple of my wikis have been overgrowing with spam. One after the other I've been closing them down to anonymous edits, even closing down user registration alltogether, but some a little too late. Read More »
