Very slow disk performance on CentOS 4.5
I recently moved my CentOS 4.5 disk from a Lenovo ThinkCentre M52
(3.2 GHz Pentium 4) to a Lenovo ThinkCentre M55 (3.4 GHz Core 2
Duo). I had to install the SMP kernel, but other than that
everything just worked. I did have an issue with accidentally
initializing my /boot partition, but that was my own fault.
But the system was not feeling right. Some things just seemed to be
slower,

Took me a while but I figured out how to put in common values of

Clustered standard errors in a panel
I want to do the following:
glm(y ~ x1 + x2 +...)
within a panel. Hence y, x1, and x2 all vary at the individual
level. However, there is likely correlation of these variables
within an individual, so standard errors need adjustment.
I do not want to estimate fixed effects, but do want to cluster
standard errors at the individual level.
Is there an automated way to do this? Nothing in

r equivalent of egen? Not tapply
I have a list that has about 50 elements, each repeated many times (a
list of states by observation). I want to create a vector with the
same length with the same value repeated over and over again within
states. The value I want is the number of observations that are in
the same state as each observation.
In stata, this is simply egen statesum = count(state), by(state).

Another system with no sound
I am also having an issue with no sound on some CentOS desktop systems. I manage about 3 dozen desktops. These are all Lenovo ThinkCentre systems of varying vintages, but there are only 2 distinct sound controllers among all of them:

Outreg-like command?
It would be nice to have something like stata's outreg that lets regression
output go into a form like
Specification (1) Specification (2)
Var 1 coef(1,1) coef(1,2)
se(1,1) se(1,2)
Var 2 coef(2,1) coef(2,2)
se(2,1) se(2,2)
I don't think this can be done in xtable?

More than doubling performance with snow
Hey my R buddies,
I installed the "snow" and "rpvm" package on my Lenovo Thinkpad T400
today. The experiment below gave me a surprise. The time consumed by
serial processing was several times larger than that taken by parallel
processing. I'm very curious how this happened. Thank you very much.

NAT-based network 2x-4x faster than routed network?
Hi
Is it expected behaviour that a libvirt NAT-based network is faster
than a libvirt routed network?
I would guess that the routed network would be the fastest one in all
cases, but I'm seeing the opposite in my setup. On a 100mbit internet
connection, the routed network tops at 4mbyte/sec, while the nat-based
network goes all the way to 10mbyte/sec. I've spend the last 6 hours

rubygems fail - require hpricot!
Hi guys,
I wanted to fetch some info from webpage and use it in my db. I read
hpricot is one way to do it. But the problem is I''m unable to use it
with my app. For some reason after successfully installing hpricot it
fails when I try to use it in the rails console.
I''ve been trying to fix this for the last four-five days. I''m stumped !

CentOS on new Thinkpads
I've had success on "older" model Lenovos.....(T-410 / T-420 / T-430) but anything beyond those seems to have some issue or another. I was even able to swap the standard drive to an SD (250GB) on a T-430 and it's running g like a champ. A lot of the newer stuff is OK as long as you don't have any boutique drivers for video network or sound. YMMV. On Sep 29, 2016 9:18 PM, John

Create qcow2 v3 volumes via libvirt
Hi all,
on a fully patched CentOS 7.4 x86-64, I see the following behavior:
- when creating a new volumes using vol-create-as, the resulting file is
a qcow2 version 2 (compat=0.10) file. Example:
[root@gdanti-lenovo vmimages]# virsh vol-create-as default zzz.qcow2
8589934592 --format=qcow2 --backing-vol /mnt/vmimages/centos6.img
Vol zzz.qcow2 created

I have configured a routed network on my laptop with a ipv6 subnet and
dnsmasq is handing out ipv6 addresses to my vms and it works really wel,
but finding out which ips have been used is not as easy as with ipv4.

Disk operations very slow on Lenovo Thinkcentre
Hi,
I'm currently trying to install CentOS 5.5 on a series of Lenovo
Thinkcentre nettops. At first, the install CD boots OK without any
options, but when it comes to formatting, the process can only be
described as terribly slow... it took about half an hour to format the
160 GB disk.
A few cups of coffee later, the system boots with the following messages
