In one of my projects I came across an interesting problem with BigDecimal values. The project uses a persistence framework to persist Java objects into an Oracle 9i database with the Oracle JDBC driver 10.2.0.3.0. I could also reproduce this problem with Hibernate on a Microsoft SQL Express 2005 database using the Microsoft JDBC driver 1.2.
The problem was that sometimes when I tried to store objects containing BigDecimal values the following exception was thrown and the object could not be persisted:

Last week I removed two mirrored hard disks from my old home server running Ubunut 6.06 LTS and put them into my new VDR. After that I was not able to boot the server again. It always stopped saying something about “… RAID autodetection …”
So RAID autodetection is a nice feature when you want to have your RAID devices available after booting the system but what if you want to get rid of it?

Today I experienced a problem with my VDR linux system I never had in the last years on any linux system. I switched on my system and wondered why I could not connect with ssh. Then I realized that no service was running - no samba, no http, no vdr …
I had to connect the PC to a monitor and start it again to see that every time a service should be started the following message was printed:

I did never really bother about what fonts to use for programming. The default of the the IDE was fine for me. Then I came across this article of Coding Horror about a month ago. One sentence in the conclusion of it made me think:
Please don’t use the default Courier New typeface. Be kind to your eyes.
So I took a closer look on what ClearType really means. This wikipedia article and the Microsoft page about ClearType helped a lot.

Yesterday I installed subversion on a Debian server again and I had too look for some guidance in the web again. This time I decided to write it down for myself.
I installed the following packages with aptitude:
sudo aptitude install libapache2-svn subversion subversion-tools Afterwards the needed modules were already enabled in my apache2 configuration - I looked in /etc/apache2/mods-enabled/ and saw dav.load, dav_svn.conf and dav_svn.load linked. All I had to do was to create a repository by using svnadmin:

Ten days ago I installed my new Linksys Router WRT45G router and set up a wireless bridge for my home network. I had some problems with getting everything working like I wanted it to - see my post.
Today I took another attempt and was successful. Now I got a secure wireless connection in bridge mode. I wanted WPA because it is much more secure than WEP and in bridge mode it is easier to reach all my devices.

Two weeks ago I moved to a new flat. This means a lot of work - one of my tasks was to set up the home network (while my wife’s task was to think about the color of the curtains 😉
I had to connect five devices: workstation, notebook, XBOX, VDR and a Linux server. While the workstation and the notebook are situated in my workroom the others are placed in the living room.

Within the last two weeks I had to experience the following BSOD (blue screen of death) several times a day:
The error always came from the win32k.sys file:
*** STOP: 0x0000008E (0xc0000005,...)`` *** win32k.sys - Address BF8E270C base at BF800000, DateStamp ... I did a lot of web searches and found many users writing about similar problems. Upgrading the video driver as many sites suggested did not improve the situation but finally I found this Microsoft feedback entry.

Today I had some problems with updating my Debian system because some of the updates had unresolved dependencies. I found out that my provider made a small mistake inside /etc/apt/sources.list- can you find it?
#deb ftp://ftp.debian.org/debian stable main contrib non-free deb http://security.debian.org stable/updates main contrib non-free #Local server: deb ftp://83.137.232.178/mirror/ftp.debian.org/debian/ sarge main contrib non-free Hint: On April 8th Debian etch was released.
In my sources.list the security updates are loaded from the stable repository and the other packages from the sarge repository.
