daemontools supervise and smbd
Hello, I'm trying to run smbd with djb daemontools' supervise. Here's the way I followed: # 2/6/2002 # problem running samba-2.2.4 and supervise problem: run smbd with supervise subproblem 1: smbd & nnmbd with -D option deteach from tty, so supervise cannot control them; solution 1: we can patch smb/server.c (foreground patch) to prevent deteach, but a second

Yeah, I had been noticing those subsets too. It sounds like it's worth a try doing a run that looks only for those. One nice thing is that if we're just looking for subsets, we will not even give the

Different labels for subsets of points in a PCA or RDA biplot
I've tried a few things both with prcomp(), and rda() and its friends in vegan (including biplot.rda and ordiplot), but can't find a solution. I'd like to associate subsets of the points in a resulting biplot ("sites" in the rda object) with different plotting colors/text styles to emphasize certain sets of points. I can't figure out how to keep the arrows (for

[LLVMdev] Google Summer of Code Projects
...resden.de/ABSTRACTS/riegel2008objbased.html). These optimizations are implemented on top of our LLVM pass (see above) and use DSA. Coming back to the compiler support, I would suggest that the project should try to use existing infrastructure (tools, code, ...) as much as possible. Many of the subproblems do have simple solutions, but integrating them can be difficult because there is a lot of interaction, and design choices can often have consequences that are hard to spot unless you have broader knowledge about TM. We can also offer support and advice regarding TM and the project's topic i...

...otion. - lazy-code-motion may be a good long term solution, but no one seems to be actively working on it. - Announcements: - flang call moved so we are no longer in conflict! - Philip is working on making loop vectorizer robust in the face of multiple exits. There are two subproblems 1. vectorizer currently gives up because scev is not giving exit counts (due to a bug?). This is relatively easy to fix and Philip will have a patch for it soon. 2. loop exit cannot be analyzed due to data dependent exit, which is currently handled v...

[LLVMdev] Google Summer of Code Projects
I'm happy to say that LLVM has 6 projects approved for Google SoC this year (3x more than last year!): [vmkit] "Generics support for N3" by Tilmann Schelle [clang] "Adding support for C++ classes in clang" by Argiris Kirtzidis [codegen] "PSP (Playstation Portable) support into LLVM Mips backend" by Bruno Cardoso Lopes [llvmir]

index problems after update
Hello List, i have a problem with index-files which is separated in 2 subproblems. May be these problems are connected. Currently we use Ubuntu 18.04 LTS which is bundled with dovecot 2.2.33.2 These servers are fresh installed machines and users are added to the system after, there was no upgrade. Sometimes it happens, that dovecot stops showing new mail. There is no error in...

Dynamic Programming in R
Hi R users, I am looking to numerically solve a dynamic program in the R environment. I was wondering if there were people out there who had expereinced success at using R for such applications. I'd rather continue in R than learn Mathlab. A concern that has been cited that may discourage R use for solving dynamic programs is its memory handling abilities. A senior researcher had a lot of

Large subjects increase memory-usage and enlarge index-files
Several times we already had the problems, that accounts with more the 1.3 or 1.7 billion e-mails in one folder run out-of-memory, even if vsize_limit of 750 MB is set. In this case, the lmtpd-process haven't been able to allocate more memory to read/write/update the index-files and crashed (and the index-files become corrupted at the end.) [Please -- don't discuss about the need of
