A new version of the naga CMS has been rolled out onto this server, yay! It mainly improves the background admin tasks, but not quite.
Every once in a while I struggle on how to deal with various login passwords. Here is an overview about the current status of my knowledge and attitude towards it...
Update: corrected some errors
On our second tour in the Alps, we hiked over the Laber to Oberau, climbing the loathing Ettaler Manndl kliff.
Update: And some minor corrections.
Update: Added pictures
Finally, we climbed our first peak of the Alps!
With the encounter with the Peissenberg, we had managed to get to the foothills of the Alps, but yet, did not reach the mountains themselves. This was the subject of our next trail, where again no man-made monuments but the landscape itself were the topic with the valley of the Ammer river as the overall subject culminating in the arrival at our first mountain of the Alps.
Update: Added link.
Update: Inserted some links.
This tour would us not lead to marvellous places, historic buildings or the like, this tour had been dedicated entirely to the landscape at the foothills of the Alps and would eventually lead us upon the Peissenberg, the first hill before the Alps providing astonishing panoramic views - backwards to the areas passed through and forwards towards the majestic ridges of the Alps that waited for us.
The next part of our tour was layed out to be the first part of a two days lasting hiking tour connected by a stay overnight nearby the groundstation of the German Aerospace Center (DLR) at Weilheim Lichtenau. It would take us from Herrsching at the lake Ammersee via Andechs, the valley of Paehl to Paehl village and terminates at the DLR groundstation in Weilheim Lichtenau.
Update: And some more corrections...

Somehow our master planner had led our group of hikers from Starnberg to Andechs, but due to some kind of ill-fated disease seizing me I could not join this tour. Truely regretting it as rumour has it that this tour was a really decent one I can do nothing but skip on to the next part, which did not take us quite forward towards the Alps but at least gave me the chance to experience the famous monastery of Andechs.
For our second part of the Grand Tour from Munich to Venice all of the eventual members of our hiking band finally had joined. So off we went from Planegg Railway station heading South to the Starnberger See...
We really gathered for the start of our Grand Tour from Munich to Venice. We hit the road at the Marienplatz, the very heart of Munich, on a sunny Saturday in March this Spring, heading for Planegg in the southern west of Munich.
People do things, all the time, all over the world. Some reasonable, others funny, quite a few weird. One of my colleagues spends most of his time either programming, thinking about geeky hobbies like water rockets or combustion engines, or hiking, be it in the vicinity of Munich or Island, no matter. And he invests quite a bit of time in figuring out new ways to go, like from Munich to Venice while passing by as many interesting places as possible. And he performs really well in motivating people, like me. Therefor here we are, five people hiking on our way to Venice, slowly but steadily ...
For a long time, the open source movement advertised open source as one means in reducing the bugs in software. Now recent severe bugs encountered within open source software seem to void this argument.

For solving ordinary differential equations, the classical Runge-Kutta method of 4th order has been well established. But there is actually not only one Runge-Kutta method, but an entire class of methods. Depending on the problem to solve, different methods of this family are favorable. Here is a short overview...
