Patch for 'packet.c' in openssh-3.6.1p1
Hello,
I just managed to compile openssh-3.6.1p1 on Ultrix/MIPS. One of the fixes
needed for this is the following. It's because of:

This IP_TOS is now nicely stuffed in a function, but that function should

Hello,

All the windows machine on our network switched today to NTLMv2, and
mount.smbfs can't access anymore ressources which are available to

Exerpt from smb.conf:
client NTLMv2 auth = Yes
client lanman auth = No

The rest being default.

The current solution is 8 years old and is reaching its end of life.
The reason we are also looking into gluster is that we like that it uses
standard components

winbind errors for trusted domain (of a one-way trust)
Hi,
Our AD domain "A.COM" has a one-way trust with "B.COM" with B.COM being
the trusted domain.
We have a samba server that is joined to A.COM on which users of B.COM
need access. We have samba and winbind configured and it seems to be
working correctly except for the following message that keeps on
appearing in the log.wb-B logfile:

[LLVMdev] LLVM for automatic differentiation or linear algebra?
Hi, no-one else has said anything more pertinent so here's my two-pence.
I have been thinking for a while about LLVM in the context of
simulating _small_ stochastic systems by which I mean very much
non-trivial stochastic transition functions, but still small enough
that if compiled carefully down to machine code via LLVM with a good
chance that they'll be faster. (With even

Gluster very poor performance when copying small files (1x (2+1) = 3, SSD)
Hi,
I've done some similar tests and experience similar performance issues
(see my 'gluster for home directories?' thread on the list).
If I read your mail correctly, you are comparing an NFS mount of the
brick disk against a gluster mount (using the fuse client)?
Which options do you have set on the NFS export (sync or async)?

Using R to process spectroscopic data
Dear R-users,
I would like to process some spectroscopic data with R, and I was hoping
some people might have some example code on how to do this.
I would like to be able to do the following things:
* Detect outlier-spectra -> This can be done by using scoreplot from the
pls package
* Determine the range of the spectrum to be used -> For this, I should
be able to calculate the regression

Gluster very poor performance when copying small files (1x (2+1) = 3, SSD)
Hi,
As I posted in my previous emails - glusterfs can never match NFS (especially async one) performance of small files/latency. That's given by the design.
Nothing you can do about it.

hello all. i have been trying to develop a representation (in the S4 sense) for a floating cash object, which would store a cash amount as a function of an arbitrary number of variables (with unknown values). for example, an interest rate swap may call for a payment in one year that can be represented as a function of a 3-month libor rate to be determined in nine months. this floating cash

The best way to use R's linear algebra functions from C
First of all, thanks to everybody for R.
I have written a program in C that requires some basic matrix
operations, namely the following:
- matrix multiplication and addition,
- determinant and transpose,
- inverse of a symmetric matrix.
Since I am a happy R user I thought I could call R from within my
program for this purpose. I read "Writing R Extensions" and "R
Internals"

matrix algebra in c
I'd like to use some matrix algebra in my c code that is called from R.
I need matrix multiplication, transposition, and Cholesky decomposition.
I haven't come across any easy way to do this, but from browsing the web
and R-devel a few options come to mind:
1. use F77_CALL() to call matrix multiplication functions from blas.
This should be ok as long as I remember that c and FORTRAN store

matrix algebra for constructing a special matrix?
Dear R-users,
would it be a better way to construct the matrix below without using any for-loop or model.matrix? preferably with some matrix algebra?
Thanks in advance,

n <- 4
mn <- m*n
k <- m+n-1

computer algebra in R
Dear Konrad,
I presume that the system can be written as follows, where h0, d0, ga0, kga and kd are given:
err1 = h + hd + hga - h0;
err2 = d + hd - d0;
err3 = ga + hga - ga0;
err4 = hga - kga*h*ga;
err5 = hd - kd*h*d;
All error terms should be zero.
Do you need (a) the symbolic solution or (b) is a numeric solution fine?
I do not have any experience with yacas or caracas. But see below.

Another issue using multi-processing linear algebra libraries
From the R Installation and Admin manual:
"There is a tendency for re-distributors of R to use ?enhanced? linear algebra libraries without explaining their downsides.?
There?s a downside not mentioned in the manual that caught and baffled me for a while. I was using all 64 cores of an AWS instance via parallel::mclapply() and doing matrix multiplications in the parallelized function. If
