Currently virtio-net code relys on the layout of descriptor, this patchset removed the assumptions and introduced a control command to set mac address. Last patch is a trivial renaming. V2: check guest's iov_len V3: fix of migration compatibility make mac field in config space read-only when new feature is acked V4: add fix of descriptor layout assumptions, trivial rename V5: fix

hello, I want to iterate through a list of names and use each element as an argument in a function. For instance: > a = c('one','two','three') > data= c() > for(elem in a){data=cbind(elem = 2,data)} > data elem elem elem [1,] 2 2 2 instead I want 'elem' to be substituted by the string in the list. Doing i...

I noticed that 32-bit flac (from git) compiled with GCC 4.8.3 or 4.9.0 calculates incorrect ReplayGain values. The most common value it produces is -55.17 dB. It is possible to avoid this bug by compiling src/share/replaygain_analysis/replaygain_analysis.c a) either without -msse2 option b) or with -O2 instead of -O3 c) another solution is to add -mfpmath=sse option along with -msse2. For GCC
