Where is all the Open Source computer algebra software?

04.07.2007

For a long time I have been puzzled by the apparent lack of a comprehensive Open Source computer algebra software, i.e. what Octave is to MatLab and what R is to S. In other words, where is the Open Source equivalent of Mathematica and Maple? For several years now I have been migrating towards Open Source for most of the software I use, with the ...

useR! 2007 – Ames here I come!

06.07.2007

Yesterday I decided that I will go the the useR! 2007 meeting after all. Initially I was a bit apprehensive, I was not sure if I had the time to spare and I like to present something when I go to meetings. I find that if I am going to time traveling (and I really do not enjoy air travel these days) I want to kill several birds with the same ston...

ESA 2007 – San Jose here I come!

12.07.2007

Finally took the leap and decided to go the ESA (Ecological Society of America) meeting despite it clashing with the useR! meeting. After checking out their smörgåsbord of a program there were simply too many yummy temptations, e.g. Alan Hastings giving the plenary and lots of epi and meta-population talks. Furthermore, this year the meeting is...

Adaptive tau-leaping in SSA

26.07.2007

Just a brief update on my activities 11 days before the R package GillespieSSA is to be released. I have been hacking away on the code, debugging, and running test simulations like there is no tomorrow. The last SSA implementation I added is the optimized tau-leaping algorithm by Cao et al. (2006) (see the reference list on the GillespieSSA page)...

GillespieSSA poster

03.08.2007

Finished my poster for the useR! 2007 meeting. It is also posted on the GillespieSSA web page as part of the package documentation. Now, all I have to do is show it off in Ames next week…, oh, and I also need to finish the package (almost forgot). Related To leave a comment for the author, please follow the link and comment on their blog: M...

Looking for a few good beta testers

07.08.2007

Sitting in a dreary hotel room in San Jose with Interstate 101 on my left and a burger joint/truck stop on my right (see previous post Report from the meeting of the Ecological Society of America in San Jose for why I have been deported here by my PI). I am writing on the documentation files for GillespieSSA. I will post the first version of the ...

Report from the useR! meeting in Ames

10.08.2007

I was not sure what to expect at this meeting. The only thing I was certain about was that I was not about to experience wiener schnitzels, waltz and Austrian high culture (in contrast to last years useR! meeting). Despite these serious shortcomings the meeting has proved to be an inspirational learning experience. The meeting is not even over an...

Things overheard at the useR! meeting

11.08.2007

Here are a few things I overheard at the useR! meeting. These comments and quotes do not necessarily represent my opinions (although many do) and since many of them were overheard in informal discussions and rants I will not name the people who expressed them. R is not only free – it’s priceless. Stay away from SAS! Real men eat pork! Bob’...

rgl: R and OpenGL

11.08.2007

There were many presentations at the useR! meeting showing off amazing graphics that I had no idea R was capable of. It is clear to me that graphically speaking I have been living in the dark ages until now. One presentation that blew my socks off was the talk by Duncan Murdoch who is a stats prof at the University of Western Ontario. The present...
