R as a server on Linux
...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!

Subsetting vectors based on condition
...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,

Changing the day of the month in a date
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

[LLVMdev] Doubts about register interferences in register allocators
...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.

Can''t change ipt_conntrack hashsize under debian sarge ???
...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 ?...

[LLVMdev] Basic questions
Hi,
The JIT engine currently uses a single memory block for all functions that
you JIT-compile (and global variables, constants, etc..). Still, 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,

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

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)

[LLVMdev] Fwd: Basic questions
Thanks, that helps. I saw the possibility to redefine function bodies
in the Kaleidoscope tutorial. What's not so clear to me yet, is how
to support multiple Modules, but it's getting clearer now.
Can I run a potential case past you just to be sure that it is/isn't
possible?
I'd like to support users dynamically adding and using functions

Analog Adapters ?
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

source questions & intentions to patch: yp-timing & auth
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

Mounting filesystems with "noexec"
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
