Wer lesen kann, ist klar im Vorteil…

Wie heißt es so schön: “Wo viel Licht ist, ist auch viel Schatten.” Dieser Spruch trifft auf die Hotline der comdirect bank zu, was ich im Folgenden ein wenig ausführen möchte.

Ich habe vor wenigen Tagen ein Partner-Gemeinschaftskonto für meine Freundin und mich eröffnet, was uns die Haushaltsführung erleichtern soll. Dieses Konto sollte sowohl nach Angaben auf der Website der comdirect kostenlos sein als auch nach ausdrücklicher Bestätigung per E-Mail:

Gern richten wir Ihnen das kostenlose Partner-Girokonto als Gemeinschaftskonto ein.

Als ich mich nun das erste Mal im Internet-Banking einloggte stellte ich zu meiner Verärgerung fest, dass für das Konto anders als zugesagt monatliche Kosten in Höhe von 4,90 EUR anfallen:

Custom paper sizes in Windows…

Monday, May 28th, 2007

My girlfriend and I are currently designing a greeting card. The cover of the greeting card will be made using “embossing technique,” and the inlay will be made from a sheet of parchment that we will print using my good, old, trusted HP LaserJet 5MP.

What sounds like an easy job (printing the sheet of parchment) turned out to be not-so-easy. The problem is that the sheet of parchment we bought in a crafting shop is not a standard DIN format, and that the printer driver for my LJ 5MP didn’t seem to allow me to create custom paper formats. No matter how hard I searched for a menu that would allow me to do that, I didn’t find any.

Grub and root on partitionable RAID1 array

For the first time I wanted to use a partitionable RAID1 array, because I wanted to spare myself the trouble of creating multiple partitions on both drives which would then be combined to individual RAID1 arrays. Instead I would have to create a single partitionable RAID1 array and partition it afterwards.

Monitor number of active connections to MySQL using Nagios

Tuesday, May 8th, 2007

I need to monitor whether the number of active connections against a MySQL server is within a “reasonable” range.

For all my monitoring needs, I use Nagios. Of course, Nagios offers a MySQL monitoring plugin, however, it does not suit my needs. It only allows you to perform queries on tables, which doesn’t allow me to retrieve the number of current connections to the database server (or does it?!).
