06.04.2015, 18:30     Bei "alexandervolf.com | A blog about linux, web and everything."

   

I encountered a common problem when preparing images for the web (e.g. this blog), from screenshots or from renders. These are usually available as .tiff or .pnm formats or have been processed with GIMP resulting in .xcf file. Converting these to .pngs or jpegs with GIMP or some viewer software makes it a click intensive task. There are a plenty of ...

38 Monaten  Skype mutes all sounds under Linux – fixed

04.10.2014, 08:30     Bei "alexandervolf.com | A blog about linux, web and everything."

   

I had lately the problem, that the new Skype version 4.3.0.37 mutes all other sounds (e.g. playing videos) when a notification sound is played. This is quite annoying, since skype normally notifies at all occasions, when a contact logs on, when a contact logs off….However this seems not be a genuine skype problem (thou I assume with a more ca ...

38 Monaten  Compression Basics under Linux

29.09.2014, 09:35     Bei "alexandervolf.com | A blog about linux, web and everything."

   

Compressing files and folders on linux is not always an easy task. This is mainly due to the lack and impracticability of compressing GUI tools under linux.Basicly the most easy way is to use gnuzip (gz) in conjuncion with tar. This can be done either in 2 steps (first create a tar container and then gzip this container) or directly using the corre ...

39 Monaten  Adding a language attribute to links – hreflang

21.09.2014, 16:06     Bei "alexandervolf.com | A blog about linux, web and everything."

   

Adding a hreflang flag to the Blog might be useful. I surely think, this could boost the page rating and make it more easily searchable. Usage is easy as can be seen in this example.There is also a wordpress plugin for adding this tag.


39 Monaten  fstab mount by UUID

07.09.2014, 16:35     Bei "alexandervolf.com | A blog about linux, web and everything."

   

I recently ran across a bug when installing Fedora 20. The installer crashed when trying to probe mdraid. This also happend when I (completely) disconnected the array from the computer. The problem was, that the installer was probing the /etc/fstab in the old fedora installation I wanted to overwrite. Here the raid array was mounted as/dev/md127 /h ...

42 Monaten  html5video – html5 video support for Gallery3

12.06.2014, 21:32     Bei "alexandervolf.com | A blog about linux, web and everything."

   

I recently wrote about some Gallery3 modules that I find useful. One Idea that came up to my mind was to implement html5 video in Galley 3. So I did that. The result is not that spectacular, but can be found and downloaded from GitHub. The big advantage compared to other video.js or flash based solutions is a better support for mobile devices.The i ...

I found this tutorial on google pagesblendercycles.comHowever it is done with a old version and I am not sure if it will work with a current version of blender.

29.04.2014, 09:23     Bei "alexandervolf.com | A blog about linux, web and everything."

   

Press this is a interesting WordPress feature. It would be interesting to midify it i  a way rhat one could “press” articles from any computer/browser without a full authentication. Kind of like a (semi–) public “Press This”.This would be a nice project for my spare time.http://codex.wordpress.org/Press_This
