Cannot Authenticate against AD ...
Hey all,
I have a Windows 2000 AD PDC that hosts a domain. He also trusts our
existing Windows NT domain (2-way trust, they both trust each other). I
also have a Gentoo Linux machine that I have compiled Samba 3.0 on. I
can get almost everything to work with regards to talking to the Windows
2k PDC, like this:

Complex conjugate?
Is there a function in R that returns the complex conjugate of a matrix
(a la 'CONJ' in IDL or 'Conjugate' in Mathmatica)?

Inaccuracy in ?convolve
Hi,
Man page for 'convolve' says:
conj: logical; if 'TRUE', take the complex _conjugate_ before
back-transforming (default, and used for usual convolution).
The complex conjugate of 'x', of 'y', of both?
In fact it seems that it takes the complex conjugate of 'y' only which
is OK but might be worth mentioning because (1) conj=TRUE is the

Best practices for handling very small numbers?
Greetings
I have been experimenting with sampling from posterior distributions using
R. Assume that I have the following observations from a normal distribution,
with an unscaled joint likelihood function:
normsamples = rnorm(1000,8,3)
joint_likelihood = function(observations, mean, sigma){
return((sigma ^ (-1 * length(observations))) * exp(-0.5 * sum(
((observations - mean ) ^ 2)) / (sigma

complex conjugates roots from polyroot?
Hi, All:
Is there a simple way to detect complex conjugates in the roots
returned by 'polyroot'? The obvious comparison of each root with the
complex conjugate of the next sometimes produces roundoff error, and I
don't know how to bound its magnitude:
(tst <- polyroot(c(1, -.6, .4)))
tst[-1]-Conj(tst[-2])

Weibull maximum likelihood estimates for censored data
Hello!
I have a matrix with data and a column indicating whether it is censored
or not. Is there a way to apply weibull and exponential maximum
likelihood estimation directly on the censored data, like in the paper:
Backtesting Value-at-Risk: A Duration-Based Approach, P Chrisoffersen
and D Pelletier (October 2003) page 8?
The problem is that if I type out the code as below the likelihood

Dialing off-hook with Polycom SoundPoint IP 430
Hi...
I've been fighting this for a while now, trying clean builds of Asterisk
1.14.18, 1.14.19rc3, and then 1.6 Beta 6 today.
No workee. :-(
Here's the results for various calls made off-hook (push the blue
Speakerphone button on the Polycom 430):

"EndCall". If I hit "Send",

convolve: request for "usual" behaviour + some improvements + some fixes
To add to the wish-list for "convolve":
For modeling processes that decay exponentially in time, e.g.,
fluorescence, it is desirable to have a function that convolves an
arbitrary vector with an exponential using an iterative method.
In the TIMP package (which won't be on CRAN till R 2.5.0 is official, but
is for now at www.nat.vu.nl/~kate/TIMP) we implemented this

supplying gradient to constrOptim()
Hi, I'm very interested in using the constrOptim() function currently in
the R-devel sources. In particular, I'm trying to fit point process
conditional intensity models via maximum likelihood. However, I noticed
that the gradient of the objective function must be supplied for all but
the Nelder-Mead method. I was wondering why this was because optim()
itself does not require a gradient

HWEBayes, swapping the homozygotes genotype frequencies
I evaluated the Bayes factor in the k=2 allele case with a "triangular"
prior under the null as in the example in the help file:
HWETriangBF2(nvec=c(88,10,2))
[1] 0.4580336
When I swap the n11 entry and n22 entry of nvec, I received totally
different Bayes factor:

Capistrano/Switchtower screencast

Hope I''m not going crazy here but I''m sure I''ve seen a screencast for
capistrano recently... maybe posted on a blog somewhere.
Can anyone remember where it is?

ANI II/Payphone indication
Quickie: Does anyone out there have experience with PRI delivery of ANI II
information?
Specifically, I want to know if it's possible from within Asterisk to know
if the inbound call (which may or may not be to an 800 number) came from a
payphone or not. I know with some 800 providers it's possible to block
inbound calls from payphones (due to the FCC surcharge etc) but was
wondering how

[LLVMdev] TSFlags in AsmBackend
Hello LLVM,
I'd like to check TSFlags in my AsmBackend code. However AsmBackend
objects don't have a reference to MCInstrInfo, which is the only way
I've seen to reach TSFlags. A quickie grep shows that none of the
existing targets check TSFlags in their AsmBackends. Is there any
reason I shouldn't check TSFlags in AsmBackend? If not, what's the
best way to go about it?

Poisson-Gamma computation (parameters and likelihood)
Good afternoon/morning readers. This is the first time I am trying to run
some Bayesian computation in R, and am experiencing a few problems.
I am working on a Poisson model for cancer rates which has a conjugate Gamma
prior.
1) The first question is precisely how I work out the parameters.

*theta<-seq(0,1,len=500)*

BB - a new package for solving nonlinear system of equations and for optimization with simple constraints
Hi,
We (Paul Gilbert and I) have just released a new R package on CRAN called
"BB" (stands for Barzilai-Borwein) that provides functionality for solving
large-scale (and small-scale) nonlinear system of equations. Until now, R
didn't have any functionality for solving nonlinear systems. We hope that
this package fills that need.
We also have an implementation of the

Tip: update dovecot MD5 password from PAM
This is a PAM module that listens for password changes, and will update
the MD5 password for a user, in a file that dovecot can read, when the
user's password is changed:
