Before everything else, I want to send a big “thank you” to our hard-working sysadmins who spent so much time and effort recently on fixing the git servers! It’s working nicely again. Other than that, there’s various news in kdevelop-land: kdev-python now has a branch which builds against upstream python 3.4 (which is not released yet), there’s a few fancy new features in kdev-qmljs (QML / javascript language support for […]
Finally, after a few days of difficult work, it’s here: the prototype for kdev-python’s new GHNS support for documentation data! kdev-python now has its own settings module providing GHNS support Technology I don’t want to go into detail here (I’m a bit sick of this stuff currently *grin*), but the OCS backend is written by me and running on my own server currently, for testing purposes. It’s python2 / django […]
For up- and downloading documentation files in kdev-python, I wanted to implement support for the KDE GHNS dialog (you know, this thing). In addition to a good GUI dialog which makes it easy for people to generate raw versions of docfiles and edit them a bit, this could be quite effective in supporting binary python modules correctly in the IDE. Sounds easy enough to do, right? The widgets are there… […]
So, since this blog’s title says something about games, and since it has been quite a while since I last blogged about something else than weird electronics experiments and kdev-python plugin development, I feel like I need to write about a game once again. Not that I’d think anyone would read this blog because it’s about games… or do you? I doubt it. Does anyone even read this at all? […]
Important: The location of the release pary in Karlsruhe I announced has changed! I’m really sorry, I hope this message reaches everybody in time! This is the first time I’m trying to organize a release party — and of course everything went wrong 😉 I wanted to wait a while before reserving a table at the restaurant to have somewhat accurate information about how many people are coming. That was […]
Important: The location of the event has changed! See below for details. I’m really sorry, I hope this change reaches everybody in time! The KDE 4.10 release is near, and since Lydia Pintscher moved to Berlin 🙁 there have not been any more release parties! This state is unacceptable and needs to be changed. Thus: There will be a KDE 4.10 release party in Karlsruhe, Germany, on Friday, the 8th […]
Have you ever seen such weird structures in a device you disassembled (or on images of such a device)? Well, I have, and I always wanted to know what they do and how they work. There’s simulation tools, even free (as in beer) ones, but I usually do not trust simulation tools unless I have verified a few of their results in reality (not because I think the guys who […]
A directional coupler is a device used in radio frequency (RF) circuits and measurement devices. Its effect is quite simple: you can picture an (ideal, 3-port, 20dB) directional coupler as a little grey box with three plugs labeled “IN”, “OUT”, and “COUPLED”. If you feed a RF signal (imagine a 200MHz sine wave) into the IN port, then 99% of that signal will be available at OUT, and 1% be […]
As you probably do not know, I’m currently trying to build a semi-digital radio interferometer at 408MHz, for astronomy. I played around a bit with patch antennas, and did some very basic “interferometry” tests with them. Some extremely bad tinfoil patch antennas being used for “interferometry” Basic idea of how this interferometer could work The plan for this telescope goes something like this: There’s an arbitrary number of antennas (the […]
Just a quick note, if you want to use usbtmc (tmc is a protocol to control measurement devices remotely), the version in the linux kernel doesn’t really seem to work. There’s one from Agilent which works fine, the installation procedure is described here. However it doesn’t compile on newer kernels unless you do these changes: http://paste.kde.org/625736/ After that, it works just fine: # cat /dev/usbtmc0 Minor Number Manufacturer Product Serial […]
