HowTo: "Qualcomm 3G ICON 210" and Ubuntu
Nov 5th
Although generally speaking I’m all pro linux and use it whereever possible – and consider it the best OS for networking encountered by me so far – I was not able to make my internal 3G modem work properly with Ubuntu yet. Of course I managed to have it load the right device drivers and I’m able to establish connections and to surf the internet – but unlike windows, ubuntu refuses to crank up the speed to HSDPA, and despite my patching (and recompiling) of the “usbserial.ko” and “sierra.ko” driver modules I was only able to get a downlink speed of 800KBit/sec at most. The same modem with WindowsXP though achieved between 2.2 and 2.8 MBit/s at the same daytime, causing me quite some frustration (I had bought the modem card because it was claimed as being fully compatible with linux, even with linux drivers supplied by manufacturer, mind you) and I started using WinXP more frequently again due to this issue.

howTo: Jaunty Jackalope with custom netbook kernel
Nov 5th
Now it has been over a week since I installed Ubuntu 9.04 “Jaunty Jackalope” on my netbook, and in the meantime I’ve been working on customizing things to my needs. One main tweak consisted of replacing the default “2.6.28-8-generic” kernel with the more appropriate “2.6.28-12-netbook-eeepc” kernel compiled by Adam McDaniel over at array.org , main reason was merely the unpleasant sound of the word “generic” to me, since this “generic” kernel was working quite well – there was no obvious need to replace it. But I still thought it would be nice to have the core of the operating system customized to my hardware.

what have fireflies got to do with BASIC?
Nov 5th
During the last days I’ve been quite excited about a certain idea I want to report about here, and which I think is quite an entertaining project. During one of my web journeys I recently happened to stumble upon this link over at instructables.com and was fascinated: I was looking at a 5×5 LED matrix that initially blinked its LEDs randomly, but somehow “magically” (with the support of 25 light-dependent resistors) synchronized them very slowly, to finally reach a state of absolute synchronicity – and all this with 25 totally independent control circuits, all based on 25 single atTiny13 microprocessors!! The whole thing should be considered as being a model of large swarms of thousands of male fireflies in sout-eastern asia, which are capable of synchronizing their blinking to attract more female fireflies over a greater distance. For more detailed explanations about the background (and how to set up a physical logic model using AtTiny13 chips and C coding) I want to forward you to the instructables link above as well as to this scientific paper explaining the underlying mathematical theory behind this..
