21cm hydrogen line telescope, version 2

Much has happened since my last status report on my attempts to observe the galactic hydrogen emission at the famous 1420.4 MHz hyperfine structure line. Now, the new setup is finally proven to be basically working, and in this post I want to describe some of the changes I did. New data acquisition module Most importantly, I replaced the spectrum analyzer by a self-made data acquisition unit which is basically […]

Snippets in Kate 5

Recently I spent some time to port and clean up the Snippets plugin and the underlying template interface for Kate 5.  It’s now fully working again and more powerful than ever. The template code was originally written by Joseph Wenniger and most of what I show here is still working like originally implemented by him. Still, there were some improvements I would like to show; also, I’m sure many readers […]

1420.4 MHz Hydrogen line: There it is!

With a reasonably simple setup, I finally succeeded in detecting the 1420.4 MHz galactic hydrogen hyperfine structure line: One of the first successful measurements. The little bulge in the center of the image is the hydrogen line. The sharp, high peaks are man-made interference and not part of the astronomical signal. The yellow line is with the telescope pointed towards the milky way, the pink line is for a different […]

Project: Detecting the 1420.4MHz hydrogen line — status report

A while ago, I decided it would be a fun thing to try to detect the 21cm hydrogen line. The 21cm line is a hyperfine structure line of hydrogen; the latter is abundant in interstellar matter in our galaxy (and in other galaxies too). That makes this transition’s radiation an interesting object to study, especially because you can determine the velocity of the regions emitting the raditation quite precisely by […]

kdevelop-python for Python 3: first stable version (1.6.0) released!

Yesterday, Python 3.4 was finally released, so I’m now happy to announce the first stable release of kdevelop-python which supports Python 3! See below for the tarballs.

Until that happens in a few days, here’s a beta: kdev-python version 1.5.80-py3 http://download.kde.org/unstable/kdevelop/kdev-python/1.5.80/src/kdev-python-1.5.80-py3.tar.xz.mirrorlist SHA256:99ca1ce97e2a7e553051be7505c17a921ab1aaf318999826ea285f771bcc538a The kdev-python 1.6-py3 series is compatible with KDevelop 4.6 (kdevplatform 1.6) and is suitable for working with Python 3.x source code. If you’re only interested in using (as opposed to packaging or developing) kdev-python, you should […]

kate: intelligent code completion for all languages!

… well, maybe that’s a bit of an exaggeration, but it’s certainly much more intelligent than before. Look: Code completion in CSS … bash … Lua … PHP even Gnuplot! Note how this one has a different set of possible items for the same query, respecting the context. Even Mathematica 😉 This image shows a problem which still needs to be fixed: in case-insensitive languages, all completion suggestions are lowercased […]

KDevelop / Kate sprint in Barcelona in January 2014

Last week I have been in Barcelona at the KDevelop / Kate sprint with all the other nice people working on those projects. As always, it was very cool to meet everyone again and spend a week together improving software. A big thanks to the organizers and sponsors, too! Since most of the time I work on a fairly encapuslated subsystem (Python support for KDevelop) and only a smaller part […]
