Saturday night and I’m not going out. What the hell is wrong with me — you (and I) ask?
Sad truth is: I’m swamped with work currently. Today I sat down and finished the last protocol of a university lab course, so at least that is done for now.
Bachelor Thesis
I’m not a slacker (even though I’d like to be one!) so I also recently started working on my Bachelor thesis. I’m doing something on EPR simulations, esp. pulse EPR with “big” molecules. It’s actually pretty interesting and I already learned tons of stuff. Most notably I could finally try out Eigen. It’s as good as I imagined, and probably even better ;-) My mentor at the university, who used BLAS up to now, is amazed by the readability of code you write. It is often nearly a one-to-one mapping of a mathematical formula to code. Since I personally never learned the BLAS interface, and find it’s API hideous, I’m very pleased to be able to use Eigen from the start. Thanks to Gael and Benoit (and the others) for writing it. Since I like living on the edge, I use Eigen 3 already and - to give something back - started to update the benchmarks for them.

Hey all!
I wanted to quickly notify you all about the availability of KDevelop 4.2.0 final, you can download it here: http://download.kde.org/download.php?url=stable/kdevelop/4.2.0/src/ . Most people should be fine with waiting for updated packages from their distributor though.
This is a feature release with lots of shiny improvements and fixes. And - which is why I announce it now - it is required for users of the new KDE 4.6. So if you happen to use that, make sure you update to KDevelop 4.2 as well. Stay tuned for a full blown release announcement on the Dot soon. If you are interested in the changes now, take a look at this, this, and that. Thanks to all contributors who made this release possible, especially I would like to emphasize the contributions by new people - welcome!

Good news everyone!
I’m happy to announce the immediate availability of KDevelop 4.1.1, a pure bug fix release. Every user is urged to upgrade to this new and improved version.
You can download the sources from one of the mirros. Though most users should get this update via a distribution package update.

Good news everyone, part 2 for today:
I’m happy to announce the immediate availability of KDevelop 4.2 RC1. This is a pure bug fix release over the last beta in the 4.2 branch. Anyone using the 4.2 branch is urged to upgrade to this new version as soon as possible. Furthermore any new testers are welcome and feedback appreciated. Report it on the bugtracker on bugs.kde.org. Keep in mind that if you are using KDE 4.6 or higher, you need this release, as 4.1 only works up to KDE 4.5. If all goes according to plan, there will be another RC soon and a final release together with KDE 4.6.
Download
You can grab the source tarballs at the usual location: http://download.kde.org/download.php?url=unstable/kdevelop/4.1.90/src/
Packagers will hopefully update the testing repositories of their distribution.
Changelog
ChangeLog for KDevPlatform v1.1.90

* David Nolden: backport from master: Don't completely ignore the retrieved top-context if it is still flagged to require an update. Instead, simply show a warning message on the status bar. (TODO: Find out why the update flag is not correct)

Good news everyone, part 1 for today:
I’m happy to announce the immediate availability of KDevelop 4.1.2, a pure bug fix release without new features. Anyone using the 4.1 branch is urged to upgrade to this new version as soon as possible. Keep in mind that if you are using KDE 4.6 or higher, you need the 4.2 branch. This release works fine with KDE 4.4 or 4.5 though.
Note: This is - probably - the last release in this branch. We are now concentrating on 4.2 and what will become 4.3 eventually.
Download
You can grab the source tarballs at the usual location: http://download.kde.org/download.php?url=stable/kdevelop/4.1.2/src/
Packagers will hopefully update the distributions, hence most people should get this release automatically via a software update.

I’ve had a major annoyance today: The plot generated by gnuplot looked good inside the wxt terminal but I simply couldn’t get a proper fullsized DIN A4 postscript exported. This is how I’ve done it now:
- Inside gnuplot:
```bash
set size ratio 0.71 # this is the ratio of a DIN A4 page (21/29.7)
set terminal postscript enhanced landscape "Arial" 9 # you can change landscape to portrait and the fontname and -size
set output 'yourfilename.ps' # this is your export file
replot # or put your custom plot command here ```
- In a shell:
```bash
ps2ps -sPAGESIZE=a4 yourfilename.ps new_dina4_file.ps ```
- Now you can simply print
new_dina4_file.ps from within KGhostView for example. Have fun!

Hey all,
I’m happy to announce the immediate availability of KDevelop 4.2 Beta 1. This is a testing version and any kind of feedback would be welcome and appreciated. Please use our bugtracker. You can download the sources or wait for your distribution to create packages.
Note: Anyone who runs KDE 4.6 or later needs this version (or any later). This is because the SmartRange interface in Kate got nuked and replaced with MovingRange interface. Many thanks to David Nolden for more or less single handedly porting KDevelop to this new architecture.
The good news doesn’t end here though, KDevelop 4.2 ships with lots of notable changes and new features:
- MovingRange` support (Thanks to David Nolden)
- Grep Plugin rewrite with replace functionality (Thanks to Silvere Lestang, Julien Desgats, Benjamin Port)
- QtHelp plugin now supports arbitrary
.qch files (Thanks to Benjamin Port) - ManPage plugin (Thanks to Benjamin Port, Yannick Motta)
- new look for code assistants (Thanks to Olivier JG)
- filter for the project model view (Thanks to Eugene Agafonov)
- improved “Problems” toolview, along with “TODO/FIXME” browsing (Thanks to Dmitry Risenberg)
- better standards compliance in the C++ macro implementation (Thanks to Dmitry Risenberg)
- argument dependent lookup for the C++ plugin (Thanks to Ciprian Ciubotariu)
- open with external application by default (esp. useful for Qt Designer
.ui files) - PHP: rainbow colors for all vars (and no nested functions or similar), esp. useful for scripts without Classes/Functions
- code cleanup for working sets
- better handling of locked sessions (locked session gets activated or the user gets asked whether he wants to remove the lock file)
- improved Snippets editing usability

Hey everyone,
the third screencast for KDevelop is in: http://blip.tv/file/4500937
It shows the advanced snippets support in KDevelop, see also: Snippets in KDevelop & Kate.
In an unrelated note: I’ll do a talk at the Computer Science faculty of the FU Berlin tomorrow, see: http://talks.spline.de/

“Wie und warum man sich als Open Source Entwickler/in engagieren sollte”
Viele Studenten könnten gute Programmierer sein, aber lassen Ihr Talent ungenutzt oder stecken es in private (kleinst) Projekte und One-Man-Vaporware. Würden sie sich hingegen in bestehenden Open Source Projekten engagieren, würde ihr Lieblingsprojekt nicht nur ein Stück besser werden, sondern sie selbst gewännen dabei eine Menge. Was ein paar dieser Vorteile sind, und wie man überhaupt damit anfängt sich in einem großen Projekt zu beteiligen, möchte ich am Beispiel von KDE zeigen und hoffe, dass dadurch ein paar mehr von euch aktiv in einem FOSS Projekt mitarbeiten werden.

Hey all,
I’d like to have some feedback from you. Consider this code:
#include <iostream>
#include <memory.h>
using namespace std;
struct List {
List(int size) {
begin = new int[size];
memset(begin, 0, size);
end = begin + size;
}
~List() {
delete[] begin;
}
int at(int i) const {
return begin[i];
}
int size() const {
// std::cout << "size called" << std::endl;
return end - begin;
}
int& operator[](int i) {
return begin[i];
}
private:
int* begin;
int* end;
};
int main() {
const int s = 1000000;
for (int reps = 0; reps < 1000; ++reps) {
List l(s);
List l2(s);
// version 1
for ( int i = 0; i < l.size(); ++i ) {
// version 2
// for ( int i = 0, c = l.size(); i < c; ++i ) {
l2[i] = l.at(i);;
}
}
return 0;
}
