For the little C test program where a constant is stored in memory and also used as a parameter: #include <stdint.h> uint64_t val, *p; extern uint64_t xtr( uint64_t); uint64_t caller() { uint64_t x; p = &val; x = 12345123400L; *p = x; return xtr(x); } clang (3.2, 3.3 and svn) generates the following X86 code (at -O3): caller: movq

I am seeing a problem with Dom0 crashing on x86_64 whenever I create a DomU. I''ve done some more testing, and it appears that this problem is somehow related to networking. Dom0 crashes as soon as the networking services are started when DomU is coming up. As an experiment, I brought up DomU without networking, and it stayed up. As soon as I started DomU with networking enabled, however,

I run cygwin and MiKTeX upadaters pretty often (every couple of days) so both of them are reasonably current. Recently I noticed a small annoyance when compiling R-dvel. It started happening right after I updated to the new

Hello. I found the behavior of knn( http://stat.ethz.ch/R-manual/R-devel/library/class/html/knn.html) function looking very strange. Consider the toy example. > library(class) > train <- matrix(nrow=5000,ncol=2,data=rnorm(10000,0,1)) > test <- matrix(nrow=10,ncol=2,data=rnorm(20,0,1)) > cl <- rep(c(0,1),2500) > knn(train,test,cl,1) [1] 1 1 0 0 1 0 1 1 0 1 Levels: 0 1 It

Full_Name: Martin O'Gorman Version: OS: Submission from: (NULL) (84.176.63.149) I have been looking at the PPC package and have a question. As the input data is comma separated, shouldn?t the command to read in the raw (no batch) mass spec data indicate that sep=?,? (marked below) ? Otherwise, the data read in is the pair of values (m/z,intensity). It is not obvious why that should be.
