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 it...

I have been trying to write a selector function for Autocompleter.Local that will show a predefined Array and will scroll automatically to the first match. I have had success with with getting my list to populate and show all of the choices, however I cannot get it to scroll to the first match. Since I build the JS Array I can know exactly how many items are in the list going into my selector,

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

Check for a "product.id" file in an architecture-specific subdirectory of the main partition, and use its data to improve the data on the media. Only Mageia as distribution name is recognized there, since most probably this file will not be available on other distros. --- Changes in v2: - simplify file reading using guestfs_int_first_line_of_file lib/inspect-fs-cd.c | 62
