I am proud to announce my new german blog: Uniadmin.
Earning money by day trading is considered to be extremely hard. I've often read that about 95% of people who attempt day trading will lose money. This might be true and coincidences with my observations among people I know, because I don't know anybody who is able to make money by day trading. But who… Read More »
Imagine you were a day trader, and you make in average one trade per day on 200 days a year. Further imagine you have to pay a commission fee of $10 when buying shares, and again you have to pay a commission fee of $10 when selling shares, which is effectively $20 per trade. So you can simply… Read More »
A Hykker mechanical keyboard with pretty nice Chinese blue switches illuminates my desktop. It's Christmastime.
In an earlier post I showed an algorithm to factorize integers using backtracking. The algorithm was implemented in python. Here we have now the same thing in erlang. To run the code, copy the script and save it to a file named "factorize.erl". Then enter a shell and compile the module using the following command:… Read More »
Today I want to compare my both favorite keyboards, an IMB Model M from 1985 and an Hewlet Packard keyboard C1405A from the 90ies. Both keyboards have a good typing sound, a good feedback, both are very heavy wighted, but I don't want to lose too many words, see yourself, which is the better one.… Read More »

The Cisco WLC prevents you from that indeed bad practice. But finally, with AC-Tube, the Open Source CAPWAP AC, you are free… Read More »
Here is an algorithm, written in Python, to factorize integers, using backtracking. The time consumption should be around . So it's not the fastest one, but it's nice. To use it, save the code to a file. If you call the file, for example, "factorize.py", then run python factorize.py <integer to factorize> Have fun!
