Calf studiogear is an extensive and high quality plugin pack for professional audio production under Linux. It provides a lot of synthesizers, effects and signal processing for the use with LV2 audio production suites (like Ardour) or as stand-alone through JACK.

Calf with all of its new features and processors isn't officially released by now so you have to grab the GIT-repository from sourceforge.net until we are ready for a stable release.

guess is a tool to launch (and kill) different setups of programs. It was invented to startup all needed synthesizers, audio suites, MIDI sequencers and stuff with the correct source files on the right desktop for a single audio production with just one click.

Lenovo Thinkpad W540 – the very last Thinkpad in my life

Freitag, den 27. Juni 2014

Notebookcheck: denting the case above the ExpressCard slotI have to admit that I was blinded by some positive tests in the relevant platforms and media and – which was much more cruicial – my own experience with high class ThinkPad machines. So nothing to euphemise – that’s what you get when you blindly trust a big business concern. It’s completely my fault that I’m a displeased owner of an expensive but  cheap piece of plastic. Sadly there seem to be no replacements on the market atm, either significant parts like a trackpoint, enough USB ports  or a high resolution display are missing, the casing is even more worse than the one of this rattletrap or the internals are too lame to sell them as a “workstation”.

Anyway. Now that I own this crappy piece of downgrade I feel like I have to make my concerns public to prevent at least a couple of people to get trapped by some clever PR. The following list sometimes refers to a comparison which implies the ThinkPad t61p, my last and dearly beloved notebook made by IBM/Lenovo.

Wifi Radar: More Improvements

Dienstag, den 27. Januar 2015

The developer of wifi-radar replied, let’s see what happens when he takes a closer look into my code. I’ve set up a git here:


Latest improvements are:

* Use scroll wheel to scroll through access points or channels
  (depending on the view)
* Select multiple channels to display with CTRL and left click
* Use ESC key to unselect individual channels
* Better speed, especially when firing up the radar
* A little clean-up
* A couple of bug fixes

Wifi-Radar: More improvements

Donnerstag, den 22. Januar 2015
* Using Pango for better font rendering
* Information about selected a/p including coloured quality bar
* Some bugfixes and performance improvements


No message from the maintainer by now :( Perhaps I have to start a completely new application for having my wifi-radar-thingy at hand.

Wifi-Radar: A Couple of Improvements

Donnerstag, den 22. Januar 2015
* Nicer a/p labels
* Better distribution of a/p
* Zoom in and out single channel by clicking anywhere
* Clickable areas with different mouse pointer
* Colors with less saturation

Source file and full package for download.

Wifi-Radar: New Realtime Radar Display

Mittwoch, den 21. Januar 2015

I did some changes to Wifi-Radar lately so it better fits my needs:

* Bugfix: crash when connection in awkward state
* Bugfix: mouse wheel not working (use GtkScrolledWindow instead of VScrollBar)
* Main window is GtkWindow instead of GtkDialog now
* Ctrl+c handler for main window
* ESSID in bold markup for better visualization
* New column in list: quality - shows a progress bar, percentual values and dBm
* New icon
* New radar display:
    * Radial visualization of access points grouped by channels
    * Signal strength visualized via distance from center
    * Legend explaining relationship of colours and channels
    * Legend shows occupation of channels as tiny bars
    * Highlight follows selection in TreeView

wifi-radar_screenshotIt’s beyond debate that the radar display can be improved much more but perhaps it’s at least a start.

I mailed this stuff to Sean Robinson, the actual maintainer of the project, let’s see what happens.

The changed source of the version 2.0.s08+dfsg-1.1 from Debian repositories can be downloaded here (put into /usr/sbin/) and the new icons (from /usr/share/pixmaps/) can be downloaded here. Install package first and copy things over afterwards. Alernatively here is the full package.

* NBMC: use high resolution size
* Templates don't need to provide configs or maps differing from default
* Updated all templates with default configs and maps (to make use of
  high definition textures re-install all templates via template daemon
  on tools tab)
