ustack() issues && correlating SIGSEGV activ ity?
Hi Ryan,

A quick look with the source browser seems to indicate that _rt_boot is code
executed very early in the lifetime of your process by ld.so.1. What seems
to be happening is that ld.so.1 has allocated some memory before DTrace got
control of your process - long before main() was

ustack()s of SIGSEGV''ed programs
Hi all,
I am trying to write a D script which would print ustack() for every
program in the system receiving SIGSEGV. All the stacks printed in
trap()/sigtoproc() context do not have meaningful symbols.
The following solves the problem to some degree but I''d much rather have
a self-contained D script.
dtrace -w -n ''fbt:genunix:sigtoproc:entry/arg2 == 11/ {

ssh-keygen listing fingerprints little unclear
Since ssh-keygen is not listing the _types_ of keys I have in my file,
wouldn't it be a good idea to make the -t switch filtering out the
selected type of key when doing a listing with -l?
i.e. in this case I see both rsa1, rsa, and dss keys:
$ ssh-keygen -l -f ~/.ssh/known_hosts

An "R is slow"-article
Hi all,
Reading the wikipedia page on R, I stumbled across the following:
http://fluff.info/blog/arch/00000172.htm
It does seem interesting that the C execution is that much slower from
R than from a native C program. Could any of the more technically
knowledgeable people explain why this is so?
The author also have some thought-provoking opinions on R being
no-good and that you should write

Building ustack() helpers on OS X without -G
I am trying to integrate John Levon''s ustack() helper for Python into the
upstream Python sources. The method for doing this on Solaris is to compile the
phelper.d script containing the helper into an object file using "dtrace -G".
dtrace on OS X does not have "dtrace -G", just "dtrace -h". This works fine for
USDT probes, but I am at a loss on how to

[PATCH] drm/nouveau/mc/ga100: make ga100_mc_device static
Make ga100_mc_device static as it isn't exported, to
fix the following sparse warning:

Project proposal for enhanced ustack/jstack
Hello,
The Hotspot JVM Runtime group would like to put forth a project proposal
to improve the capabilities of DTrace''s ustack()/jstack() actions to
better handle non-standard user stack frames. This email will describe
the background, the problem, and our proposed solution. We''re
interested in getting a sponsor for this work to help us with the
process of getting the

[Cucumber] Cucumber and acts_as_xapian
Hey list,
Anyone have experience with acts_as_xapian and Cucumber? I''m
struggling with updating xapian''s index, to actually "find" fluff

ustack() wrong in pid return probes?
I have a test program which has a call sequence of
a(), b(), c(), d().
When I place a pid return probe on d(), I get a ustack that
looks like this:
a.out`d+0x19
a.out`b+0xd
a.out`a+0xd
a.out`main+0x3c
a.out`_start+0x7a
The c() method appears to be missing.
I did some poking around and noticed that pid return probes

Newbie Question
I'm sure this or similar questions have come up previously but I'm looking for a more definitive answer. The company I work for is in the process of going from Win NT 4/2000 (yeah we're up to date) to server 2008. However as I'm sure many of you know the costs are insane with having to re-buy licenses and what not. We've already purchased 2 new servers one of which for SQL

How accurate is "ustack"?
I have been doing some profiling using the profile provider. I have a
command that runs more slowly on the T1000 than it does on prior
systems and I am trying to find out why. Using the profile provider at
1000 hz, and aggregating on the ustack output, I find that the same
function appears at the top of the stack on both platforms, but on
each there are specific instruction locations within

"A critique of R and S-PLUS"
Dear all,
The other day I stumbled on this article, "A critique of R and S-PLUS"
[1], and got curious on whether the points outlined are (still) valid.
The article is quite old, dating 2004, but was updated several times.

Official GUI Speex player
One thing that is keeping Speex from being adopted is a lack of GUI
players. I think that Speex could benefit from an offial cross-platform
GUI player. The goal of the player should be to be stable, to the
point(no fluff like visualisations, playlists, an equaliser, etc.), self
contained(no external .DLLs, etc), and to be small(500k or less) so that
people with modems don't have to wait

R crashing inconsistently within for loops
Hello,
This one has been bugging me for a long time and I have never found a
solution. I am using R version 2.15.1 but it has come up in older versions of R I have used over the past 2-3 years.
Q: Am I wrong to expect that R should handle hundreds of iterations of the
base model or statistical functions, embedded within for loops, in one
script run? I have found that when I write scripts that do

oVirtBIOS : Virtualization Firmware
Misters,
Let me introduce myself : Guillaume FORTAINE, Engineer in Computer
Science. Me and my partners are currently working on a Virtualization
Firmware.
After an analysis of the various solutions (Citrix, VMware and
Microsoft), it seemed
natural to our eyes, to enable a true bare-metal hypervisor, to go as
close as possible
to the hardware, hence the BIOS.
That's why we are currently

sip.conf help, inbound calls fall to last specified context
First of all, if Asterisk is the client and it must register to the other side, does the peer\user entry have to be in sip.conf, or can it be in ARA?
Second, why do all calls fall through to the last context specified, whether in that peer\user definition or not? I'm assuming it's a typo somewhere, but I can't find it. I had a full sip.conf, but axed a lot of the fluff trying to

Cleaning Up My Process Table
I'm upgrading my primary server from RH 7.2 to CentOS-4.3.ServerCD. I
REALLY like the ServerCD. Who needs all the fluff that comes with a

and ssh -X from my laptop. Anyway I have two questions:
1) How can I collectively stop all the NFS, portmap, whatever? I'm hoping
it can be manipulated as a group because occationally
