More Microbenchmarking

[This is a follow-up on a previous entry.]
I did some more micro-benchmarking, adding four more languages to list: Perl, LISP, Dylan and Scheme.
To all critics of microbenchmarking: I think these benchmarks do yield more undisputable numbers than many “real-world” benchmarks: The LOOP and the CALL benchmarks mark absolute upper limits: You will not be able […]


Die bundesrepublikanischen Volksvertreter der 15. Legisllaturperiode sind natürlich in aller Pracht im Web vertreten; auch die der 13. und 14. Periode sind so nett aufbereitet. Da stehen Dinge drin, auf die bei Jauch oder Pilava kaum einer kommen würde, jedenfalls ich nicht:

In welcher Stadt wurde Angela Merkel geboren?


Ja, die Antwort ist Hamburg.

Benchmarking Ruby, Python, JavaScript, Lua, Java, C++ and Assembly language

I admit it, I am a performance fetishist, maybe that’s the reason why I always looked down on the web a bit, and why 3D realtime visual simulation is still my favourite field of development activity, but I admit, cpu cycles are cheap and still getting cheaper, and human brainpower is expensive, and will be more expensive in the future, […]

Programming Languages

Found myself recently spending some time thinking about programming languages. My preferred language is still C++, which I have mastered almost at guru level. You can do incredible things with modern C++ design, but with all those people using JAVA, Python, Ruby and even C#, I might become a FORTRAN or COBOL programmer of our time: maybe respected, but […]

Does Windows XP suck?

Actually, from time to time, it sucks big time. Recent example: The webdav client. First of all, it takes 5 (!) clicks before you can enter the address. Then, if you want to authenticate, you will be presented a dialog where you can enter username and password. So far, so good, but if you expect that the client will use […]

Nickel-Metallhydrid Akkus

…in Form von AA oder AAA Standardbatterien sind eine feine Sache; von der Kapazität her kommen sie mittlerweile praktisch an Einweg-Alkali-Batterien heran; eine Mignonzelle (AA) erreicht als Alkalibatterie höchstens 3000mAh, NiMh-Akku inzwischen bis zu 2500 mAh. Alkali-Batterien sind aber nicht hochstromtauglich, bei 5oo mA Stromentnahme halbiert sich die Kapazität, bei 1A bekommt man nur 500 mAh raus, also gerade […]


Finally all the pieces came together. Some weeks ago I took a nice old box with PentiumII-450 with a 9GB Fast SCSI disc, silenced it and started to install gentoo linux from the scratch. After weeks of quite smooth compilation and configuration, I finally have a rock solid gateway and server connected to my dsl line, running apache2, php, […]
