Hello All, I am (proudly?) announcing a new Ajax SlideShow project. It is part of a new bigger project starting up, still I am glad to announce you this early snapshot. Please consider taking a look at http://slideshow.webtwo.ws website The project itself - as long as the web page hosting it - it''s not as clean as it will be. I must also admit that, even if announced as release

...ed Hat Linux 9, running samba samba-2.2.7a-7.9.0. We have client PCs running both Win98 and WinXP, but only the ones running WinXP display the problem. Sometimes, when opening a file or a directory, there's a delay (about 20/30 seconds). The problem seems to happen completely at random, and is unrepeateable (closing and reopening the same file/dir shows no delay at all). Now, assuming I'm experiencing the problem described in the above links, (Microsoft Knowledge Base Article - 811169, "Update to Increase the Performance of the Network Redirector"), is there a way I can test for that? T...

I'm aware that there are IEEE requirements for floating point. But all C/C++ compilers like GCC or MSVC have unsafe/fast math switches that disable all problems related to NaN/Inf/+-0/precision etc because in some applications those are not as important as performance (for example graphics calculation). But as I understand, LLVM currently does not have such unsafe/fast math optimizations

I found out the other day that crossprod() will take a single matrix argument; crossprod(x) notionally returns crossprod(x,x). The two forms do not return identical matrices: x <- matrix(rnorm(3000000),ncol=3) M1 <- crossprod(x) M2 <- crossprod(x,x) R> max(abs(M1-M2)) [1] 1.932494e-08 But what really surprised me is that crossprod(x) is slower than crossprod(x,x): R>
