I started performing some very basic performance analysis of interesting parts of the Math.NET Iridium (Numerics) Library, motivated by a forum post . Machine Configuration I tested it on the following computers: A : Desktop, Intel P4, 3.4 GHz , XP SP2...

I've finally tried Sandcastle to automatically generate class references from the inline xml comments, as a replacement for the discontinued NDoc. The result for Math.NET Iridium is now available for download (in both HtmlHelp CHM and Ms Help 2 HxS...

There was quite a huge check-in lately on the yttrium source code repository . I've been refactoring the yttrium code base to a new microkernel based architecture (motivation: getting rid of cyclic dependencies and the high degree of complexity)....

My server is currently being "attacked" by a chinese computer at 220.173.30.198 , what resolves to - you guessed right - China Telecom: netname: CHINANET-GX descr: CHINANET guangxi province network descr: China Telecom descr: No.31,jingrong street descr:...

Because information about this is actually hard to find (there are loads of samples around about how to demand several rights, but hardly any about locking down your own frameworks & assemblies): I recommend for most cases to start from no rights...

Sogar in deutschen Heise Newsticker wurde heute vom schweizer Verbot von Radarfallenwarner in Navigationssystemen berichtet . Wie dem Diskussionsforum unschwer zu entnehmen verstehen viele diese Massnahme nicht. Häufig gehörte Argumente: Die Warner schützen...

I'm currently working on the Iridium (Math.NET Numerics) Fast Fourier Transformation Implementation, to finally fix known bugs and improve its usability (make it easier to work with). I expect a new Iridium release this week. What's new: Unit...

In case you ever wondered how to explicitly implement interface properties in C++/CLI that collide with an already existing better typed property: It's quite easy, but I didn't find a sample in neither the language specification nor the web. Imagine...

Seltsam. Immer wenn ich wieder mal etwas von einem total absurden politischen EU-Vorstoss im technischen Bereich lese - kommt in den letzten Jahren öfters vor - stosse ich garantiert spätestens einen Absatz weiter auf den Namen Brigitte Zypries...

I'm fighting with a strange behavior of the MS PowerShell RC1 , that might be a bug . It's about moving and renaming items with "[" or "]" in the name. Strangely they're simply ignored, sometimes I also get a message that...

I think it would be really interesting to propagate the new MS PowerShell as a new interface for Math.NET, especially for the Yttrium project. Yttrium already provides very simple script support, but PowerShell has so much more to offer. I think about...

Das Dauerthema: Management-Gehälter. Ich habe kein grundsätzliches Problem mit hohen Vorstandsgehälter, aber manche machen es sich klar zu einfach. Zum Beispiel Siemens. Siemens hat sich kürzlich für Vorstandsmitglieder Anhebungen...

I'm used to enter a unique email address whenever I really have to provide one. Up to some weeks ago I used the "reg.{0}@mydomain.com" pattern, where I replaced "{0}" with a name I associate with the site, often the second level...

Looking back at my first semester thesis at ETH , where I designed a full-custom ASIC , I realize something odd: In VLSI design, especially when designing ASICs or ASIPs (not so much on FPGAs), people make a real fuss about testing . For a good reason,...

Enough Sudoku for a while? Try Kakuro ! I've created a small helper table lately, listing what numbers are possible in what condition (dependent on the required sum and the number of fields). You may download it as a PDF (see attachment): I could...

As I have mentioned before, for me, Math.NET is not only an interesting math project, but also a kind of play ground to try out new concepts and strategies. In fact I actually learned real object oriented programming in C# with Math.NET (and another project:...
