MediaWiki problems with MySQL VARBINARY padding

I have been wanting to protect a certain page on my Dutch 15Monkeys wiki for weeks. I could install the ReCaptcha extension already (the best Captcha there is), but it's just that one page that's being spammed. So far, I've been unsuccessful in regaining my Sysop right for that wiki. I need these rights if I'm going to protect these pages. Read More »

In all the time since I've upgraded (and increasingly with every update), I've started to like it more and more. I hadn't thought it possible but everything just felt at exactly the right place, while before 2.5, the whole always felt like it had been thrown together by a blind child. Had I written it myself, it would have at least felt as being thrown together by an adult (chimpanzee). Read More »

Creating a custom device node for specific hardware with udev

Sometimes you want specific hardware to get a specific device name in /dev. For example, I want my backup hard disk to have the same device name. I can't automate anything if sometimes the device is sdc and other times it's sdd. Read More »

Clonezilla as disk imager

I was always using partimage to make backups of the hard disks of workstations. When trying to restore one the other day, it just started giving CRC errors. After recreating the image and running a simulated restore, it gave CRC errors again. So, apparently, it's not incidental. It must be due to the experimental NTFS support. So, I set out to find a new tool. And that's how I found Clonezilla, which gives me a very good first impression. Read More »

Gentoo update: Portage configuration confusion
