how to access the elements of a univariate results table with Anova (library car)
Dear R users, I use the excelent Anova function of the library car because
the easy way to get sphericity correction. Unless I use the scan function. I
have not been able to access the values of sum squares and degrees of
freedom for each effect in the univariate summary table.
Example of the car library for Anova function:
library(car)
phase <- factor(rep(c("pretest",

How to stop a loop for?
Hi all, I have some time trying to find a way to stop a loop for( ) until the
user presses the enter key or any other one and the loop can continue.
This could
be an example:
library(MASS)
data <- data.frame(mvrnorm(1000,rep(0,5),Sigma=diag(1,5)))
for(i in 1:dim(data)[2]){
plot(density(data[,i]), main=paste('histogram',i))
#here something like waituntil command
}
Thank's in

That?s probably from package iptables-services, which isn?t

pinning CPU affinity
I''m trying to figure out how I can pin the CPU affinity for individual
domU''s in their configuration file.
I allocated 3 CPUs to a particular domU, and the CPU affinity is
floating between those three. I want to pin them to specific cores in
the config file. I can do it on bootup by doing vcpu-pin on the
command-line, but I want this to be set int he config file itself.
Right

Samba Printing Question
Hello Samba Gurus:
I have a unusual printing problem on a Samba server (version
samba-1.9.18p7) on a Solaris 2.6 server.
Basically I had 2 Solaris 2.5.1 machines that were retired when this new
machine was deployed. Each individual machine had Samba shares and printers
on it individually. Those file systems and printers were then duplicated on
the new server. The version of Samba was the same

[LLVMdev] Stack protector performance
If you compile this with optimizations, then the 'canary()' function should be totally inlined into the 'main()' function. In that case, the cost of the stack protectors will be very small compared to the loop.

weakforced and GeoIP lookups
Hi Tobi,
it should just work, but depends on the OS version.
./configure ?help tells you all the configure options, including:
--with-maxminddb-includedir
path to maxminddb include directory [default=auto]
--with-maxminddb-libdir path to maxminddb library directory [default=auto]

Mocking Access Control
I''m trying to jump on the TDD/BDD bandwagon, but am having trouble
understanding how i should mock my user. The user has a habtm
relationship to a roles model (acl_system2 plugin), but I''m not sure
how to tell rspec about a model.
My code:
describe UsersController do

according to yum list installed I have

but even running a new autoreconf -i and ./configure after a make clean
it still shows that GEOIP is not found.
Does the lib has to explicitly specified as argument

weakforced and GeoIP lookups
Hi Tobi,
This looks like you haven?t included the libmaxmind libraries before running configure. GeoIP support is only compiled in if it finds the right libs.
This would be libmaxminddb-dev on Ubuntu for example.

Encoding raw to Theora
Hi Ralph,
Sure, we had our mind set on the NC-ND CC licence, and we would be delighted
to help by providing the source master.
Actually the editor had decided not to use FCP since he has to think the CGI
globally before coming down to editing.
Thank you,

[LLVMdev] Stack protector performance
I have a question about the performance of the implementation of the stack
protector in LLVM.
Consider the following C program:
=====
void canary()
{
char buf[20];
buf[0]++;
}
int main()
{
int i;
for (i = 0; i < 1000000000; ++i)
canary();
return 0;
}
=====
This should definately run slower when stack protection is enabled, right?
I have measured the runtime of

[Kernel 3.1.5] [OCFS2] After many write/delete on ocfs2 both servers in cluster kernel oops

Marek,
Thanks for the detailed report! Can I trouble you to file a bug
at http://oss.oracle.com/bugzilla ... oh, is that your report
http://oss.oracle.com/bugzilla/show_bug.cgi?id=1339?
This looks like a deadlock of some sort. I don't think your
hardware configuration really matters here. We'll keep looking into it.

[LLVMdev] Question about SimplifyXorInst
Hi all,
I am master student in Edinburgh, UK. I am doing my MSc project with
LLVM compiler and I have to modify LLVM to implement the StackGuard
with a XOR random Canary. However, I am not familiar with LLVM.
My problem is that I want to XOR the random canary word with the
return address which are both 32 bits. I found a method called

Strange Error -- ASterisk 1.6
All,
I just noticed this in my logs, and am rather lost as to what module

but I am looking for a little confirmation from the group:

[LLVMdev] How to get the return address on the stack on LLVM
Hi all,
I want to implement the Xor random canary, so I have to get the return
address in the prologue and epilogue of the function.
In the prologue of the function, before I insert into the canary on
the stack, I can get the return address by:
ConstantInt* ci =
llvm::ConstantInt::get(Type::getInt32Ty(RI->getContext()), 0);
Value* Args1[] = {ci};

Hace mucho tiempo, no recuerdo cuanto, creo que casi todos encontramos en español dos artículos, uno de Argentina otro de Colombia, ambos en español, es lo que yo recuerdo, uno tenía el título de revista de bioingeniería, el otro de R para principiantes, o gráficos en R para principiantes, seguramente aún deben estar en el repositorio de R, documentación en español.
