Keep-timestamp-in-`get'-patch for smbclient in samba-2.0.3
--------
--Multipart_Thu_Apr__8_13:33:51_1999-1
Content-Type: text/plain; charset=US-ASCII
Hello guys,
I always wondered why smbclient keeps timestamp in `put'ting a file
but does not keep it in `get'ting a file. Alternative to keep the
time stamp in `get'ting file is to use -Tc option or smbtar script,
but they are a bit hairy for interactive use, and it can only dump
files with an

1 dimensional optimization with local minima
I am using numerical optimization to fit a 1 parameter model, in which the
input parameter is bounded. I am currently using optimize(), however, the
problem turns out to have local minima, and optimize does not always seem to
find the global minimum. I could to write a wrapping function that tries
multiple intervals or starting values, but I would prefer a package that has
built-in methods to make

rsync: always modify atime of all destination files
Hi Everyone,
The following feature request was received by a Debian user; could you
comment on it? I think this seems reasonable, but perhaps should be
enabled only conditionally (as if the argument parser isn't stressed
enough).
Thanks,
Justin

3.0.24 smbclient and printer listing
I'm using 3.0.24 with patches from http://us4.samba.org/samba/patches/.
On my XP client the print services for Unix are installed, I shared the
local printer named 'jet' on the XP client to all users and the
connecting user is an existing user on linux (system and samba user) and XP.
I cannot execute the dir command in smbclient for this printer:

DEoptim 2.0-0
Dear All,
We are happy to announce the release of the new version of DEoptim
(version 2.0-0) which is now available from CRAN.
The DEoptim package [3] performs Differential Evolution (DE) minimization,
a genetic algorithm-based optimization technique [2,3]. This allows robust
minimization over a continuous (bounded or not) domain.
The new DEoptim function calls a C implementation of the DE

Schwefel Function Optimization
All,
I am looking for an optimization library that does well on something as chaotic as the Schwefel function:
schwefel <- function(x) sum(-x * sin(sqrt(abs(x))))
With these guys, not much luck:

[1] -7.890603
> optim(c(1,1), schwefel, method="SANN", control=list(maxit=10000))$value

Multiple Clients, Winbind and idmap in LDAP, documentation incorrect?
Hi!
I have a setup with several Linux machines running
samba-3.0.22-10.1.17 (from SuSE 10 OSS), authenticating against an
AD. Since one of the machines is exporting an NFS share mounted by
the rest of the machines, I need SID <-> uid/gid mapping to be shared
between all Linux machines, which led me into using an OpenLDAP server
as idmap backend. My smb.conf is found at the end of this mail.

Manipulating text files
Dear R Community,
I am trying to optimize a water quality model that I am using. Based on conversations with others more familiar with what I am doing I plan to implement DEOptim to do this. The water quality model is interfaced through a GUI. I have the input file necessary to alter parameters and run the model as a text file.
To do the optimization I have figured out the general procedure

DEOptim Parameters
I am trying to figure out how parameters are defined in a function that is used by DEOptim. That is, when I set upper and lower bounds for DEOptim how does it know which element of the function to apply those bounds to? For example, in DEOptim call below, when DEOptim goes into "optimfxn" how does it know what element of "optimfxn" to apply the upper and lower bounds to?

bug in DEoptim package
(the same mail was sent to the author)
When I called the function DEoptim with control=list(strategy=1) or
control=list(strategy=2)
I got the error:
Error in mui[rtd + 1, i] : incorrect number of dimensions
Analysis of the source code of the DEoptim reveals the following fragment

DEoptim example illustrating use of fnMap parameter for enforcement of cardinality constraints
Function DEoptim in package DEoptim for differential evolution defines an optional parameter fnMap:
fnMap
"an optional function that will be run after each population is created, but before the population is passed to the objective function. This allows the user to impose integer/cardinality constriants."
Unfortunately, there is no further documentation decribing the kind of

Sum of Product in a Matrix
Hi,
I am new in R and I don?t know how to sum the product of two elements at the
time in a matrix
X=[ 1 5 9 13
2 6 10 14
3 7 11 15
4 8 12 16]
I would like to do (1*5+2*6+3*7+4*8)
I need to do it step by step because I will further put a conditional in the
formula
It worked this way
x <- matrix ( c (1 : 16),ncol = 4) #generating my x matrix

How to mask or escape "=" in Windows command prompt?
I have defined a function with several arguments and have it stored in the

How to find all single minima, i.e. only each one within each next part of analyzed vector (table)
Dear R users,
How to find all single minima within each next part of analyzed vector (table)
Select all minima (mass_value=min & mass_value<2)
(many) in vector(table),
BUT first put mask on table in order to select
within one window mask (5 elements) only one local minimum, and next to search within
the next time window mask the second minimum (only one local along second mask)
