processing a large matrix
I would like to compare every column in my matrix with every other column and
get the r-squared.
I tried using the following formula and looping through every column:
> summary(lm(matrix[,x]~matrix[,y]))$r.squared
If I have 10,000 columns, the loops (10,000 * 10,000) take forever even if
there is no formula inside.
Then, I attempted to vectorize my code:
> cor(matrix)^2
With 10,000

loop issues (r.squared)
I would like to compare every column in my matrix with every other column and
get the r-squared. I have been using the following formula and loops:
summary(lm(matrix[,x]~matrix[,y]))$r.squared
where x and y are the looping column numbers
If I have 100 columns (10,000 iterations), the loops give me results in a
reasonable time.
If I try 10,000 columns, the loops take forever even if there is no

LEGO LOCO: startup error
I've installed successfully LEGO LOGO, a game made by LEGO Media.
But, when I run it, I get a messagebox with the following error:
?LEGO LOCO only runs in High Colour (16-bit) 800x600, 1024x768 and
1280x1024. Please change to one of these settings.?
Is there any workaround for this? Or must I change xorg.conf?
(I'm using 1024x768. I suppose the problem is depth - mine is perhaps 24.)

simulating RED using tcsim question
I''m trying to setup a bottlekneck scenario so I can see the effects of
the RED qdisc on a congested interface.
My example simulation code is at the bottom of this email if someone
wants to see it.

DRS replication metadata not getting deleted
We have a test samba setup containing two domain controllers (both running
samba v4.1.6). Recently we created an ldap group, added around 5000 members
to it and then deleted the users from the directory. We set
tombstoneLifetime to few days and waited for these ldap objects to be
purged from the system.
But we notice that the particular group has slowed down considerably for
all ldap operations.

Once again in search of memory
Hello any R user,
Working on R 1.8.1 or R 1.9 on Windows, 256 Mb RAM.
I am trying to debug/correct/speedup the execution of one of our student's
program. Basically, we perform simulations.
R is launched with high memory-limits.
One execution of the program requires nearly 200 Mbs and is OK the first
time. Then, launching it again does strange things: seen from Windows

eliminating control characters from formatted data files
I have a few hundred files of formatted data. Unfortunately most of them end
with a spurious CONTROL-Z. I want to rewrite the files without the spurious
character. Here's what I've come up with so far, but my code is unsafe
because it assumes without justification that the last row of df contains a
control character (and some NAs to fill up the record).

City of Heroes / wine not identifying NVIDIA video card
I've been using wine for some time now to play City of Heroes and overall I've been very satisfied. One issue that has always bothered me is that COH gives a warning about outdated video card drivers even with the most recent drivers from NVIDIA installed. This limits the settings that can be chosen in the video options. I also suspect it's not making the most efficient use of my

using rsync 3.0.0 CVS version
Hi,
I've wanted to start working with this CVS version cuz the new
"incremental-recursion algorithm" is just what I need. But ran into a
problem...
When I start the rsync, either with the rsync protocol or rsh, i found that
it'll start doing the rsync and just halt after a few hundred MBs or even up
to a couple GBs.
I was never able to finish an rsync.
Anyone else had this

Newbie wants to compare 2 huge RDSs row by row.
Each RDS is 40 MBs. What's a slick code to compare them row by row, IDing row numbers with mismatches?
Thanks in advance.

Roughly how many more months before CentOS 8.0 release?
Where can we learn more about the workflow and software used to build
CentOS RPMs and iso images?
This will be extremely helpful to everyone facing the same challenges of
building a custom distro.
Thank you all for the hard work on CentOS.

OT: syncing
Hi,
An offtopic quesiton, but I could not think of asking any other list
where it might be answered.
I have a client uploading a few designs (25-30 Mbs) daily at a remote
ftp server. We download them in morning. Since we have a slow
connection we daily waste a couple of hours downloading it. Is there
any way I can download them at night. The only thing is that I am not
sure of the time they

IAX2 one way audio
Experiencing one way audio using IAX2.
I did see some other posts on this, and see there may be some internal issues with asterisk and one way audio. Can this be a widespread problem? So many seem to be using IAX, I find it puzzling.
Some information points to this being a problem on asymmetrical connections. This is a decidedly asymmetrical connection, with 1.5 Mbs download and 256 kbs,
