Yet another blog

Hi there,

Welcome to yet another blog. This blog won't be about my pets, since I don't have any :) It'll be mostly about computers. I'll try not to waste too much time giving my opinion on software or sites, but focus more on usefull information for specific problems/setups. If you have any questions or remarks (stuff that's outdated),... please leave a comment.



Solution for vboxconfig SSL error:02001002:system library:fopen:No such file or directory:

Apache2 on Ubuntu 12.04 Basic Auth: password mismatch

The default instructions to have basic http authentication failed on Ubuntu 12.04 Precise Pangolin. The reason seems to be that the htpasswd tool produces MD5 hashes by default, while the default apache2 installation on Ubuntu 12.04 expects SHA1 hashes. The symptoms are that login attempts always result in password mismatch:

Mounting a disk image file with partitions

Installing Funambol on a 64-bit Ubuntu

This is something that I found out by installing Funambol 7.1.1 on an Ubuntu 8.04.3 amd64 (virtual) machine:
Funambol uses it's own packaged sun java 5, but it's a 32-bit version. The service doesn't seem to start with /opt/Funambol/bin/funambol start, and strace seems to give the error "/opt/Funambol/tools/jre-1.5.0/jre/bin/java: No such file or directory". But the file is definitely there! The problem is that this java is compiled against 32-bit libraries. You can either force every script in Funambol to use a 64-bit java, or you can install 32 compatibility libraries with


Audio and Video over HDMI with Ubuntu on Dell Studio 15

If you have a notebook or pc with HDMI output and a big LCD TV with HDMI input, you might want to connect those. Unfortunately, this doesn't work out-of-the-box with the Dell Studio 15 notebook, neither with Vista nor with Ubuntu.
Now I got it working both in Vista and Ubuntu (8.10 - Intrepid Ibex).

In Vista I needed to update the AMD ATI Mobility Radeon™ HD 3450 driver
download Vista driver from Dell.
Then you need to configure windows to use the HDMI audio output.
