Commenting fixed for blog.bigsmoke.us

To my great surprise, thanks to Tobias Sjösten, I found out that commenting was broken on blog.bigsmoke.us. I couldn't pinpoint the exact problem, but it must have been introduced with some WordPress upgrade somewhere along the line. I never noticed it because it did work for logged in users. (If I must really guess, I suspect a silent ReCaptcha version compatibility problem.) Read More »

Psychopathic Saturday

I'm trying to pump up myself to write a piece of text about psychopathy. All three other group members already wrote their part. We're making a scientific poster titled “Is there a psychopath hidden in your brain?” But, do I even want to know? It's all very close to home, with a mother who's been accusing her ex-husband (my dad) of being a psychopath for, like, forever, and, simultaneously, this monkey in my brain, pointing it's accusative little finger straight at me.

I am naked and feeling very vulnerable

There are many clever ways to tell you this. There are many ways to deceive. But in the end I feel that more often than not the deception merely serves to reinforce that image of a very vulnerable naked man. Read More »

MediaWiki ConfirmEdit/QuestyCaptcha extension

Since I moved my LDAP wiki over from DokuWiki to MediaWiki, I've been burried by a daily torrent of spam. Just like with my tropical timber investments wiki, the ReCaptcha extension (with pretty intrusive settings) doesn't seem to do much to stop this shitstream. Read More »

Safari: don’t give gzipped content a .gz extension

Yesterday, while helping Caloe with the website for her company De Buitenkok, I came across the mother of all stupid bugs in Safari. Me having recently announced payformystay.com, I loaded it up in Apple's hipster browser only to notice that the CSS wasn't loaded. Oops! Read More »

Announcing payformystay.com

Januari the first, a very good day to announce a new project that I've been working on this past year. Which I did, on Facebook and Twitter. Now, five days later, it's time te repeat the announcement to give it some much-needed link-juice. I know that normal people don't follow this blog. (I don't even follow this blog!) But it does have PageRank. And it does have 4000 monthly visitors. Time for some link-whoring! Read More »

Setting max memory of a Xen Dom0

I've had some issues with Xen crashing when I wanted to create a DomU for which the Dom0 had to shrink (see bug report). Therefore, it's better to force a memory limit on the dom0. That is done with a kernel param. Read More »

Fixing a broken Xen DomU after upgrading to Ubuntu 11.4 (Natty)

My Xen DomU's that I upgraded to 11.4 no longer booted, because the xen-blkfront module is missing from the initramfs. To fix, do this when you get the initramfs prompt: Read More »

Fixing a Xen DomU’s grub config

When you use xen-create-image to bootstrap an ubuntu, it sets up a grub config file menu.lst. However, this boot config is not kept up-to-date with newer ubuntu's because they use grub2 (which uses grub.cfg and not menu.lst). And Xen's pygrub first looks at menu.lst, so if you have a stale file, it will always boot an old kernel. Read More »

CUPS printer driver for my HP4050

My HP4050 has a million different drivers to choose from. Some don't have the maximum DPI, some don't have other options, like selecting paper output. The one that works the best seems to be "HP LaserJet 4050 Series Postscript (recommended) (grayscale, 2-sided printing)". However, I have no idea anymore if that came from hplip, foomatic, gutenprint, or whatever. Read More »
