...f Brian for your suggestion. I should know that for right-skewed data, one should generate the samples from a lognormal. My problem is that x and y are two instruments that were thought to be measured the same thing but somehow show a wide confidence interval of the difference between the two intruments.This may be true that these two measure differently but can also due to the small number of observations, so the idea is if I increases the sample size then I may get better precision between the two instrument by generating samples based on the means and standard deviations from x and y. I a...

...O NOT USE) More work-in-progress for comment. More work on the sshd hooks, the implementation in port-solaris.c is still incomplete. I'm interested on feedback about (a) whether or not the interface (see sshaudit.h) is sane and (b) if it's adequate for other systems requiring this kind of intrumentation. ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee.

To my knowledge that intrinsic IS generated by frontends like Clang when using _builtin_return_address(), i could be wrong though Zhang > 在 2018年9月5日，10:47，Bekket McClane via llvm-dev <llvm-dev at lists.llvm.org> 写道： > > and

Hello, I wanted to find out more about square polar mapping, cause that whole stuff is a bit tricky - to me - and not so easy to understand. Searching the web did't get me any results, so I wonder what the background of square polar mapping is. Is it derived from some mathematical publications or just the result of a brilliant intuition of a Vorbis programmer ? ;) Thanks. Stoffke

Is it possible to emulate a unionfs with zfs and zones somehow? My zones are sparse zones and I want to make part of /usr writable within a zone. (/usr/perl5/mumble to be exact) I can''t just mount a writable directory on top of /usr/perl5 because then it hides all the stuff in the global zone. I could repopulate it in the local zone but ugh that is unattractive. I''m hoping

I've put together the first attempt to defining an RDF metadata vocabulary for use with the CD Index/MusicBrainz/OggVorbis. If you care about metadata issues, please take a look at: http://www.cdindex.org/MM I've included a section for video specific stuff, but everything that I originally had in there is being covered by the MM:Contributors section.

They were running low on memory (requiring smbd stop/start) one to four times per day. I'm drowning in other work, so I haven't intrumented a running daemon with a memory leak detector. But I needed to slow the rate of consumption so that the servers continue to serve files and mail to their (500) clients. The work-around: Install the xinetd service on the servers.
