...itecture is such that My Java client explicitly calls R in batch mode and passes it certain parameters. The initital startup takes almost 10 seconds because R has to load a bunch of libraries as well as a moderately large, previously created workspace. I am thinking that it would be so much more eficient to instead have R act as a server and fork off a thread for each client query. Is that possible at all ? Thanks! Markus

...vect.2 <- c(63, 95, 133, 170, 215, 253, 285, 299, 325, 375) I would like to subset vect.2 so that it has the same length as vect.1, and its numbers are the first corresponging higher value compared to vect.1. The output should be: final.output = (95, 215, 299, NA) What is the fastest/most eficient way to accompllish this in R? Thanks for the help in advance, Mahesh Krishnan

Hello, I want to change the day of the month in a date object. What I am doing at the moment is: x=as.POSIXlt(x) x$mday=13 x=as.Date(x) Does anybody know if there is a more "natural" (eficient) way to do this Thank you Felipe Parra [[alternative HTML version deleted]]

...aph colouring (I know, everyone has already done that :-)) and I'm also using LLVM 3.4 from master branch. The algorithm I'm using is based on the one described on the "Modern Compiler Implementation in C". My implementation is totally experimental and doesn't aim to be fast, eficient or even faster than the current allocators (so please don't say "you'd better use a better algorithm" :-)). I've been reading the code of current allocators as well some documentation about them in blogs, etc., but I still have some doubts. I need to create a graph with t...

...evious mail and this http://www.wallfire.org/misc/netfilter_conntrack_perf.txt) CONNTRACK_MAX = 2876 * 64 = 184064 HASHSIZE = 2876 * 8 = 23002 But the near power of 2 is 2^16 = 131072 ... I''m not sure that if it better to put 184064 or 131072 ? Seems that netfilter algorythm is more eficient with power of 2 value ? I can set the CONNTRACK_MAX value but not the HASHSIZE ... I''ve tried add hashsize= paremeter in /etc/modules or in /etc/modprobe.d/arch/i386 and I''ve done an "update-modules" ... When reboot the server the value still 8192 ???? Any Ideas...

...l, you can easily create and delete machine code. You can use the following functions: engine->freeMachineCodeForFunction(function); // clean the JITed code function->eraseFromParent(); // clean a function's IR About the lifetime of the classes, its better to create them only once, for eficiency sake. Allocating PassManagers each time you compile a given piece of code is slow (and probably not useful as you can reuse it).

Hi, I apologize in advance if this is not the correct place to ask these questions, but I would be very grateful for redirection to the appropriate list/docs if so. I've just started with LLVM in the last week or so, and have worked my way through the Kaleidoscope tutorial, the IR docs & programmers manual, plus a few of the examples; everything makes sense. But there's one

.../executable in order to verify access (most > flexibile) and/or make icecast perform a HTTP request to an auth-server > that returns 200 or 403 (most portable). That would be really cool to have, please share patches =) But I think having it call an outside program is not really elegant nor eficient. Implementing new auth methods is quite easy, you can see here for basic post with no auth (... have that pending in my todolist) http://thread.gmane.org/gmane.comp.audio.icecast.devel/1692/focus=1705 Hope it helps, Cheers, -- Niv Sardi

I have a friend with a small business running a small SIP based phone system. He was looking into providing some SIP phones for a couple of remote teleworkers, but as he started to look around and ask me questions he ran across analog adapters which made him curious. He proceeded to ask me if there was an analog adapter that provided the following functionality in which my reply was simply,

Good Day, Looking at the SVN repo: there's 30+ commits since the 2.6.2 release; the last one from August 2009. Are there any intentions to roll a release anytime soon? Are there any more recent branches? I'm currently looking into extending icecast2 (more below) and am wondering if I should base the patches on 2.6.2+debian-fixes or work from svn-trunk? We are using a cluster of icecast

Hello, I've been playing a bit with the "noexec" flag for filesystems. It can represent a substantial obstacle against the exploitation of security holes. However, I think it's not perfect yet. First thing, an attempt to execute a program from a noexec-mounted filesystem should be logged. It is either a very significant security event, or it can drive nuts an
