I have released version 0.2 of the Java GNU Scientific Library (JGSL) project, its second public alpha release. Please visit the JGSL project website for more information. This second release provides additional wrapper classes for the GSL stats module (mean, variance, standard deviation, etc.). Feel free to try it out and get back to me […]
Ubiquitous home automation will never become a reality unless cheap embedded PCs are available to be the “brains” of the home. Some time ago I came across a company called Soekris Engineering who make relatively cheap embedded PCs, like the one shown below. This little guy packs a 20Gb CompactFlash harddisk, 128 Mb RAM, and […]
We have made Apache Felix run successfully on the UNC90 embedded platform and here I’d like to share our experience. Our UNC90 runs on an ARM9 chip with 16 Mb flash and 32 Mb RAM. It runs the uClinux operating system. The flash is divided in four partitions according to the linux/drivers/mtd/maps/modarm9.c file in uClinux’s […]
I have released version 0.1.0 of the Java GNU Scientific Library (JGSL) project, its first public release. You can download it from here. This first release provides Java wrapper classes for the Special Functions module of the GNU Scientific Library (log, exp, airy, bessel, etc). I’ve run some preliminary tests on the log function, that […]
I have already mentioned elsewhere that the OSGi technology is likely to play an important part in the computerization of current and future buildings. It is a very attractive programming model for building management systems, especially with respect to its software lifecycle model (stopping, updating and restarting) that does not require a reboot of the […]
The GNU Scientific Library (GSL) is a rich state-of-the-art C library of mathematical routines. Pretty much everything you could think of—special functions, linear algebra, function optimization, fast Fourier transforms, and much, much more—is covered by this library. I have taken over the open-source Java GNU Scientifc Library project at SourceForge. The plan is to write […]
If you are regularly programming in your work you should invest some time to keep your programming skills sharp. And one of the best ways to do that is to master a new programming language. I have now been through two major programming projects in Java, and am starting on a new one in Python. […]
I came across an article in the 15th International Symposium on Software Reliability Engineering (2004) titled “A Comparison of Bug Finding Tools for Java“. The authors, Nick Rutar, Christian B. Almazan, and Jeffrey S. Foster, have carried out probably the first detailed comparison of the most popular automatic bug finding tools for Java. They tested […]
