You will read what happend. Yesterday I gave a talk about Smrender at the Linuxwochen 2012 in Vienna. Three things happened the first time. …

Debian Wheezy on Acer Aspire One Happy

A few days ago I successfully installed Debian Wheezy 64 bit (currently sid) on an Acer Aspire One Happy notebook. Most of the built-in hardware seems to work out of the box. Display, touchpad, sound, and webcam works. Solely the SD card read is unable to reader my SD cards. This seems to be related …

A not so trivial IPv6 tunnel setup

History and blahblah Since several years I am dealing with IPv6. To be more exact, this is since about 2007 when we started to talk about the DNS-leak-problem of Tor. At the end of 2008 way came up with Onioncat at the 25C3. Although it did not solve the original problem it still is a …

Kmail does not ask for PGP password

A few days ago I fucked up my Debian installation. It ran properly for several years but because of mixing different repositories (squeeze, wheezy, backports,…) aptitude somehow lost track about packet versions. I spent several hours but was unable to fix it. It just got worse. Thus, I decided to do a completely fresh installation …

Polyline Refinement with Smrender

It highly improves the appearance of the map specifically in such areas which are just “roughly” mapped. Ideally, it is applied to the coastline, for example. Polyline refinement is invoked rule-based. It is an internal function. The following shows …

Undefined control sequence. \Gm@lmargin ->\Geom@lmargin I found out that this seems to be caused by an update of the geometry package. The …

C Source Code Analyzer for Graphviz

I am currently working on a graph based visualization tool for the output of an i386 emulator. The basic idea is to do some kind of intelligent malware analysis and behavior prediction. I experimented a little bit and suddenly got the idea to do some kind of source code graphing of some of my programs. …

Rendering Depths with Smrender

Rendering Depths with Smrender I started to experiment with the rendering of depths with Smrender. At a first glance this looks trivial but one might err. OSM data as well as a chart is just a two-dimensional plane. So, where’s the problem? As long as the elevation is monotonic, observed from any point in the …

Smrender now uses GNU Autotools

After publishing Smrender I got several mails regarding the compilation and installation process. Mainly because I just used a simple Makefile and because it was not tested on other operation systems beside my Linux computer. Thanks to all beta testers for now! I now introduced the GNU Autotools into the Smrender package, thus the compilation …

Smrender released into the wild

It was hard work to create smrender and it was even more work to create a documentation for it. And both are not finished yet. But nevertheless I decided to release it now. I have talked a lot about it and there are several articles about it found in the Internet. It is time now …
