FAOF & SSL

October 22, 2009

Heute war ein Vortrag über FOAF&SSL in der Marienstraße, interessant aber es basiert stark auf Secure-DNS, nicht praktikabel zur Zeit.

Migrated the subversion server from old Sony notebook to new Dell Mini 10 netbook.

Configure external disk

October 10, 2009

I bought the Patriot-Convoy-XL Raid case (eSATA&USB), equipped with two 250GB WesternDigital HDDs. The raid device shall be mounted as external USB-2.0 device. To avoid collisions with other USB storage devices, the device shall be detected via unique UUID.

The following command lists the UUID of all connected disks
> ls -lF /dev/disk/by-uuid
frehberg@freza:~$ ls -lF /dev/disk/by-uuid
total 0
… 3220f76f-0967-4fe8-ad70-b97bca895bd6 -> ../../sda5
… 4c7a980e-b3a6-4ae3-8225-53f0a448b474 -> ../../sda1
9cd4ffd9-40b2-4968-9d9d-dbb82255370d -> ../../sdc

I want the device being mounted at  /media/raid/, I have got to create first
> sudo mkdir /media/raid

Add the following line with text editor to /etc/fstab, so the device with UUID 9cd4ffd9-40b2-4968-9d9d-dbb82255370d will be mounted beneath /media/raid

# line added to /etc/fstab

UUID=9cd4ffd9-40b2-4968-9d9d-dbb82255370d /media/raid     ext4    relatime       0        1

Finally unmount the device /dev/sdc and mount it under the new branch

> umount /dev/sdc

> mount -a

Linux & G500/poulsbo

October 4, 2009

Dell Mini 10 is a Linux-nightmare, but this page is quite helpful:
http://wiki.ubuntuusers.de/Grafikkarten/Intel

And Modeline needs to be added:

This is also useful:

Finally I modified /etc/X11/corg.conf the following way, to run stable and support my external screen with 1400×900 resolution:

Section “Monitor”
    Identifier “Configured Monitor”
    Modeline “1440x900_60.00” 106.47 1440 1520 1672 1904 900 901 904 932 -HSync +Vsync
EndSection
Section “Screen”
    Identifier “Default Screen”
    Monitor “Configured Monitor”
    Device “Configured Video Device”
    SubSection “Display”
        Virtual 2464 900
    EndSubSection
EndSection
Section “Device”
    Identifier “Configured Video Device”
    Option “AccelMethod” “EXA”
    Option “DRI” “off”
    Option “MigrationHeuristic” “greedy”
EndSection
