Create Image Gallery

19. September 2016 Keine Kommentare

More a note to myself.

Put all images in folders and create a corresponding file in each folder:

Title: Fuschoelpass (18.08.2016)
Representative: DSC01775.JPG

## Fuschoelpass (18.08.2016)


Resize all images in each folder:

for file in *.JPG; do convert $file -resize 1920 $file; done

Generate Gallery using sigal:

sigal build source . ../generated

Compile rtl8812au Driver on Raspbian (Kernel 3.18.5+)

2. September 2016 Keine Kommentare

I tried the everywhere mentioned method with, but this was not working as expcected. Therefor I tried the method mentioned on the Fedora Mailing List. This does not contain the patches for the Raspberry PI. The Makefile needs to get adopted, so that you can compile this driver on the Raspberry Pi.

The compile seems to work now. I have uploaded all sources to Github. In this repository is also the 8812au.ko, which is compiled on a Raspbian Box with Kernel 3.18.5+. Hope this will work out now.

Finally I have made it and ripped the whole CD collection of us. The whole collection can be seen on discogs. I will add new CDs in there, if those are added to the ripped cd. The whole process took more then one and a half year (well, I really starte end of Mai 2013), but I guess, it was worth it.

If you need some nice Topographic maps for hiking purposes, you can download those at

Another good source seems to be

There are two kinds of Maps. The ones on the left side are for the use with the Garmin device. I usually copy those to the SD card in the directory /Garmin.

Update eTrex 30 with Linux

3. September 2014 Kommentare ausgeschaltet

I am a proud owner of an Garmin etrex 30. Since I do run Linux on all my machines at home, I tried several ways to update the firmware of this device. Unfortunately this is not possible, using WebUpdater from garmin directly. A tool which should make it easy (and most probably it does on windows and/or mac) makes it hard to do on Linux.

Anyways, a download of the lates firmware can be found at You just need to rename the Downloaded file to GUPDATE.GCD and move it to /Garmin/ on your Garmin device.

After a restart of the eTrex 30, all seems to be fine.

Rotate Images based on EXIF Tags

15. August 2014 Kommentare ausgeschaltet

Back from vacation I am currently in the process to create an image gallery using sigal.

Unfortunately sigal can only copy EXIF tags to the (smaller) images in the gallery or rotate the images correctly.

Since this is needed for some of the pictures, I have done, I use jhead.

The following line is quite helpful to rotate jpgs based on the EXIF tags:

find -name "*.JPG" -exec jhead -autorot {} \;

IntelliJ on ArchLinux

After the latest upgrade to OpenJDK (7.u60_2.5.0-2) my IntelliJ version was not working correctly anymore.

After browsing, I found this solution:


Worked like a charm ;-)

MPD and ALSA settings on cubox-i

31. Mai 2014 Kommentare ausgeschaltet

I have had some trouble with some songs playing on my cubox-i via the SPDIF-Toslink connection. I heard crackling noises on those songs. First I thought, that those were due to some mistake done during ripping those from my CDs. But I tested those songs on some other devices and recognized, that it is most probably due to high frequencies or something similar.

Therefor I digged into the concrete settings of ALSA and MPD to fiddle around with Frequency- and Volume-Settings. In the end it turned out, that the solution is rather easy and I just had to reduce the volume of the cubox-i SPDIF out to 98%. Now all crackling noises are gone and I can enjoy the music via my home stereo system.

Here are the settings of ALSA (/etc/asound.conf):

pcm.imxspdif {
type hw
card imxspdif

pcm.imxhdmisoc {
type hw
card imxhdmisoc

ctl.imxspdif {
type hw
card imxspdif

ctl.imxhdmisoc {
type hw
card imxhdmisoc

The above settings are just setting the devices in the Cubox-I to be used by alsa. The “imxspdif” is important, because this one is used by the following MPD-setting:

audio_output {
type "alsa"
name "imxspdif"
mixer_type "software"

Unfortunately I could not use “alsactl store” to store my alsamixer settings, therefor I have set the mixer_type of MPD to software, which allows to call the

mpd volume -2

command inside of my mediaplayer-startup script. This command sets the used volume to 98%. Now everything is working fine, on every boot, like wanted ;-)

IPv6 on Netcup using ArchLinux

21. April 2014 Kommentare ausgeschaltet

I just enabled IPv6 on my Netcup Server, this is quite easy. There is one real important point in the documentation (found here): “poweroff” is needed, without this, the Adress will not get assigned to the VServer.

I am using netctl for the configuration, and my config looks like this:

Description='A basic static ethernet connection'


## For IPv6 autoconfiguration

## For IPv6 static address configuration
DNS=('2001:4860:4860::8888' '2001:4860:4860::8844')

Note, that IPv4 is configured via DHCP whereas IPv6 is configured static. Furthermore the gateway for IPv6 is set to the current machine, this is according to the documentation of Netcup (found in some forums). Furthermore I did configure some DNS-Server here. These are the ones of Google.

You can then use ping6 to ping some hosts and test, if the connection is working. The host is reachable from the outside with the given IP.

New DVD Drive

2. März 2014 Kommentare ausgeschaltet

Since I have ripped around 900 CDs with my Laptop, the build-in DVD Rom broke (which is bad, but to be expected on this large amount of CDs). I bought a new external drive (Samsung SE-218CN). This one works now without any problems on my ArchLinux Laptop ;-)
