nested anova not giving expected results
Hello all. This may be a trivially simple question to answer, but I'm a little
bit stumped with respect to the calculation of the F statistics in nested
anovas in R. If I understand correctly, the F statistic for the
among-subgroups but within groups hypothesis is calculated as
MS_subgroups/MS_error, while the F statistic for the factor is calculated as
MS_factor/MS_subgroups (I'm

Default password hash
We still have MD5 as our default password hash, even though known-hash
attacks against MD5 are relatively easy these days. We've supported
SHA256 and SHA512 for many years now, so how about making SHA512 the
default instead of MD5, like on most Linux distributions?

Hi,
I am performing a repeated measures 2-way ANOVA to assess the influence of
plant and leaf on aphid fecundity. Fecundity is measured for each aphid on a
single leaf.
Here is what I typed.

Error: C stack usage is too close to the limit
Lately R has been behaving strange on my Linux (Ubuntu 7.10) machine,
with occasional segfaults. Today something else and reproducible
happened:
If I type the code below (meant for calibrating data), I get the error
message that "the C stack usage is too close to the limit".

Convergence problem in GLMM
Dear list members,
In re-running with GLMM() from the lme4 package a generalized-linear mixed
model that I had previously fit with glmmPQL() from MASS, I'm getting a
warning of a convergence failure, even when I set the method argument of
GLMM() to "PQL":

sftp chroot requirements
Hi Damien,
Thank you. I read the rationale.
Just to summarize, a user writeable chroot target is considered
dangerous if:
1) the user has another way of gaining non-chrooted access to the system
2) is able to create hardlinks to setuid-binaries outside of the chroot tree
3) there are bugs somewhere that allow privilige escalation or remote
execution of other programs
While all these

Disabling specific commands in sftp
Hi,
On CentOS 7 I?m trying to set up a chrooted SFTP server on which specific users can only read and write on specific folder. And I?d like to disable some commands, so the users can only do ?cd?, ?ls?, ?get? and ?put? (and disabling ?chgrp?, ?chmod?, ?chown?, ?df? etc ?). Is there a way to achieve it, natively or with using a third-party software ?

anova planned comparisons/contrasts
Hi,
I'm trying to figure out how anova works in R by translating the
examples in Sokal And Rohlf's (1995 3rd edition) Biometry. I've hit a
snag with planned comparisons, their box 9.4 and section 9.6. It's a
basic anova design:

I wrote the following batch script on a iMac, and ran it on a linux
mosix cluster.

assessing the fit of a LME model
Dear All,
I would like to ask a couple of questions on a LME model.
I tested 4 selection lines at 4 food concentrations against a standard
competitor stock. I had 3 replicate cages per selection line. In each cage
I have 10 vials. I counted the number of wild type flies and competitor
stock emerging in each vial. My main question is: is there any difference
between selection lines?

[PATCH] nsd-patch: fix segfault after renaming slave zone
Hi all,
we have discovered a segfault in nsd-patch when renaming slave zone in nsd
config file if some data for this zone still exists in the IXFR diff

In my case, the zone "black" was renamed to "blackinwhite":

using OpenSSH/SFTP to replace an FTP server securely
Hello Folks,
I'm trying to replace an FTP with several hundred users with something secure.
My requirements:
- transfers must be logged
- users should not have any access to other users' directories
- users should land in a writable directory
- users should be chrooted
I've been trying to get this working with OpenSSH and the internal SFTP server,

multiple disk failure
Hi,
I am using FreeBSD 8.2 and went to add 4 new disks today to expand my
offsite storage. All was working fine for about 20min and then the new
drive cage started to fail. Silly me for assuming new hardware would be
fine :(
The new drive cage started to fail, it hung the server and the box
rebooted. After it rebooted, the entire pool is gone and in the state
below. I had only written a few
