How to define stopping criterium for Optim with L-BFGS-B
Hi,
I am using optim with a L-BFGS-B method to minimize a function. As I've
understood, the way to specify a tolerance for stopping optimization is
through "factr" argument.
My function, is by construction, minimal when equal to 1. I wonder if there
is any way to pass this info to "optim". If not, how "factr" argument works
(I am quite confused about the

Link AD to pre-existing UNIX accounts
I'm trying to use winbindd to enumerate and link AD users to their pre-
existing UNIX accounts. Right now, winbindd creates new "users" for UNIX based
on windows username and groups.
What I can't figure out is how to explicitly map the AD users to their pre-
existing UNIX accounts. I'd like the users to be able to access their UNIX
accounts with their UNIX authentication

[LLVMdev] recreate optimized clang output
...ain "somewhere else" (externally), and the optimizer will find in some other module to possibly inline it later on.
I am planning to concat all the *.ll (eg "link" the files) and pass them to the "global" optimizer, as "size" is a very important optimization criterium to me. After that, the back-end will be invoked.
Is that a good approach?
Best, Patrick

How about just add -O4 on clang (or llvm-gcc) command line to get LTO optimizations ?

data.frame: how to extract parts
...the R syntax.
It's perhaps pretty simple, but I don't understand it ...
I can extract a column from a data.frame with the following code for
example ...
b$row1[b$row1 == "male"]
so I see all male-entries.
But I cannot extract all lines of a data.frame depending on this
criterium;
only.male <- b[b$row1 == "male"]
With that, I get an "undefined columns selected" message.
So how can I extract lines of a data.frame depending on a level
variable?

send specific NDR message for users in certain OU
Hi,
The question can perhaps be made more generic like this:
Can dovecot generate a *specific* NDR (or an autoreply) for accounts
that meet a specific criterium, such as:
- user account was found under OU=to-delete,CN=company...
contrary to the regular location CN=Users,CN=company...
We would like to move to-be-deleted users to this container, before
actually deleting them. That gives us an easy way to revert, if the
deletion turns out to be erroneous....

regularly lattice & neighbors
Dear R-users,
Is there a procedure to identify neighbors in a regular lattice using either a
"rook" or a "queen" criterium? To be more specific, suppose:
My lattice:
1 2 3
4 5 6
7 8 9
"Rook" Neighbors
1 has neighbors 2,4
2 has neighbors 1,3,5
...
5 has neighbors 2,4,6,8
"Queen Neighbors"
1 has neighbors 2,4,5
2 has neighbors 1,3,4,5,6
For each case, the final output would be a 9x9 matrix with...

matching country name tables from different sources
Hi,
Before I reinvent the wheel I wanted to kindly ask you for your opinion if there is a simple way to do it.
I want to merge a larger number of tables from different data sources in R and the matching criterium are country names. The tables are of different size and sometimes the country names do differ slightly.
Has anyone done this or any recommendation on what commands I should look at to automize this task as much as possible?
Thanks a lot for your effort in advance.
All the best,...

Which Quad Port FXO is Best?
...63
I know it would be cheaper to buy two more Sipuras, but it might be
worth the extra $$ to cut down on the power adapters and have a
centralized point of administration, especially if it didn't involve
dozens of browser mouse clicks to 3 separate HTTP servers. Reliability
is the primary criterium, though.
Can anybody give any recommendations? And are these digium problems
unusual?

Optimization problem
...:3)
{
s <- x[i]^3 + s
}
s
}
optim(rep(4,3), method="L-BFGS-B", lower=rep(-10,nlin), upper=rep(10,nlin))
It would return '-10' for all variables. I want, however, a solution
satisfying mean(x)>7.
Please, don't analyse this specific example, but the logic of satisfying a
criterium for the mean of the input (with thousands of variables). My real
problem involves price elasticity and I want to find the price increase for
each individual that would give me maximum total profit margin, but
respecting a minimum retention of clients.
Thank you very much,
John Mayer

executing from .R source file in the src package
...nction. This is just
lovely as I'm sure everyone knows. However, in case of a trace on function
in a package (ie loaded from a .rdb/.rdx) there is no filename/linenum
information probably because its not retained. i.e. it prints something
like this:
debugging in: train(net, P, target, error.criterium = "LMS", report = TRUE,
Any way to work around this? Thanks for all insights.

Setting the grid of a graph of timeseries

####################################################################
This code produces a graph with a non-decimal x-axis but by far more (human)
readable because ticks corresponds to months exactly (and not to a weird
decimal ticking!).
I would like to add a vertical grid with the same criterium.
How can I obtain this?

Patch to sshd match
Please find attached a patch against openssh-4.7p1
It extends the Match in sshd_config. The point is that it is sometimes
easier (and more secure) to match on NOT something.
A criterium may be preceded by ! which inverts the condition, thus:
Match !Group sysadmins
ForceCommand /usr/bin/sftp
forces use of sftp on any user who is not a system administrator.
A !! has the same effect as no ! - but I didn't document that.
I am looking at sftp, extend it:...
