Until Fedora 15 I somehow managed to get the NVIDIA driver and the CUDA compiler running, but Fedora 16 seems to quite of a hurdle. I tried something similar as for F15, including a patch which solves the Kernel version…

Fedora 16 and CUDA
Merging my homepage and this blog
For long time I was keeping my homepage up-do-date and I have been posting on this blog. More than half a year ago I ported my homepage to Drupal and thought that things become more easy, but it turned out…

Formal errors of bilinear interpolation
The bilinear interpolation is a quite useful mathematical approach when it comes to interpolation in a two- or higher-dimensional regular grid. Other than a nearest neighbour approach or simple block averaging, this method provides a somewhat “continuous” field. Thereby, one…

The impact of constraints on linear least-squares problems
OK, this post is going to be a little bit longer than the usual article which I am writing here. First, I was thinking to summarize my thoughts in a short note, but why not post it here directly? So…

Applying the KLT to my blog stats
A few months ago I wrote about the Karhunen-Loève Transform (KLT) which could be an interesting alternative for continuous wavelet transforms. I almost forgot about that topic, but today I stumbled over it again. Thus I applied it to my…

About NVIDIA CUDA and Fedora life cycles
Most of my real-time stuff (mainly signal processing) runs on the GPU and I really like CUDA because it is as simple as C or C++ but allows you to tune your graphic card to get the maximum performance you…

Karhunen-Loève Transform – an interesting alternative to FFT and wavelets
Today I stumbled over this interesting paper which describes the usage of the Karhunen-Loève Transform (KLT) for (weak) signal detection in time-series. Although there are many similarities with wavelet analysis, the KLT seems to be less computationally demanding (but its…

Fedora 15 and CUDA
Driven by the curiosity for GNOME 3.0 and a little bit fed up with the Ubuntu installation on my GPU laptop I decided to install F15 on that machine. All my other PC’s are running F12 or F13, which are…

GMT 5 is coming
The Generic Mapping Tools (GMT) are a convenient software package for displaying data on a large variety of map projections. Until now data could be converted into GMT native (i.e. NetCDF) format and then output to postscript. With the announcement…
