Ubuntu Realtek ALC1150

I got a new mainboard with Realtek ALC1150 onboard sound. First I was thinking it doesn’t work, but it only was very silent. Here is how to fix this:

sudo apt-add-repository ppa:ubuntu-audio-dev/alsa-daily
sudo apt-get update
sudo apt-get install oem-audio-hda-daily-dkms
sudo reboot




I just installed a google translator plugin to this blog (see right) because I was asked to write translations for some posts. I think it is very redundant to write everything more than once. So I hope google translator is sufficient. So please don’t hang me if a translation is wrong/bad.

I created my SSL certs with easy-rsa. But it seems most browsers have tightened their certificate checks so my self signed certificates and my authority haven’t been working the last days. But I can’t really say how long SSL was down. Chrome decided to ignore my old ca.crt and firefox displayed sec_error_inadequate_cert_type. So I had to recreate my ca.

As I found no good tooling to create a certificate authority I decided to write some scripts to do it manually and fully automated.

Now all my sites are available via SSL and if you install my ca.crt you won’t see errors for certificates signed by me anymore.

Openstreetmap Offline Map Data

I was looking for openstreetmap data of my country to import it into a local database. As only small areas can be exported over the exporter of the official web page I followed the hint to planet.osm which would contain data of the whole planet. After some reading I found where you can download map data for single continents or single countries. Quite nice and useful work!

Conclusio self signed SSL certifacte

After a few weeks with a self signed SSL certificate I had a closer look at the site statistics and as thought before still lots of people don’t visit a site behind a self signed certificate. Because I don’t want to spend money for a certificate I made the whole site accessible via http instead of redirecting everybody to the secure SSL site. Now the user has the choice to use http or https.

Of course I created a redirect to SSL for all login/admin stuff.

SVN: exclude folder from update

I had to checkout a very large repository which included branches, tags and trunk in a subfolder of the project. So checking out the basedir gets all branches and tags which makes SVN very slow. So I was looking for a way to exclude folder from checkout. The following statement makes SVN ignore and delete folders locally but lets them untouched on the server.

svn update --set-depth=exclude <foldername>

After this the folder with name <foldername> is deleted and wont be updated anymore. This is NOT the same as the svn:ignore property!
