rtmvt
I have been using the rtmvt function in the {tmvtnorm} package i'm getting
the warning:
"Acceptance rate is very low and rejection sampling becomes inefficient.
Consider using Gibbs sampling."
but i AM specifying the gibbs algorithm!!:
rtmvt(M, mean=q[,,i,j], sigma=((u[i,j] + nu[i])/(p+nu[i]))*delta[,,i],
df=ceiling(nu[i]+p), lower=c(0,0), algorithm="gibbs")

truncated distributions
I am sampling from the truncated multivariate student t distribution "rtmvt"
in the package {tmvtnorm}. My question is about the mean vector. Is it
possible to define a mean vector outside of the truncated region? Thank you
in advance for any help.

tmvtnorm: version 1.0-2
Dear R users,
the tmvtnorm package, the package for the truncated multivariate normal and Student-t distribution, has been updated on CRAN.
The major changes in version 1.0-2 (2010-03-04) are:
* The package now provides methods for the truncated multivariate Student-t distribution, i.e. random number generation, density function, distribution functions like rtmvt(), dtmvt() und ptmvt() and

rtmvt
I want to use the rtmvt from the {tmvtnorm} package using the "gibbs"
algorithm but how to i specify the nested function rtmvnorm to use gibbs as
well?
Right now I am using the code:
for (i in 1:g){
for (j in 1:n){
sgamma[,,i,j] = rtmvt(n=50, mean=mu[i,j], sigma[i,j],
df=nu[i], lower=rep(0,2),algorithm="gibbs")
}
}

1.0-test53, sig11 when sorting by thread
Hello.
When trying to sort a folder by thread (with pine4.61), I get a sig11.
The mailstore is Maildir, indexes stored in /var/indexes/%u.
The syslog on the server shows this:

D-bus integration
Dear OpenSSH developers,
I was looking at the fail2ban project and had an idea that instead of
parsing log files it could be possible to notify interested parties
(like fail2ban) via (for instance) D-bus about a failed login attempt.
Other application could also use this protocol to notify about suspect
behaviors. A central functionality will allow for other (new) projects
to integrate

migration to maildir and arrival time
Hello.
I am currently testing dovecot (0.99.10.8, Debian woody from backports),
with the maildir storage.
I have noticed that when I use the mailutil tool from uw-imap
distribution to transfer my IMAP mailboxes from our current server
(uw-imap, mbx format) to the dovecot one, the mails arrival time are
apparently lost. I can see this in Pine, using the Arrival sort: the

Instance variables versus local variables
This novice coder roughly understands the difference between instance
and local variables thanks to David Black''s excellent book, but I''m
still unclear as to when and why a either is more desirable to use.
In general, I use instance variables in my controller and local in my
views, but I''m not sure as to why or if this is correct.
Thanks

using win32 DLLs in Linux
Hello,
I have a win32 DLL library, which I can't decompile, and can't get it's source
code, but which I'd like to use in my Linux program. I wondered about making
a win32<->Linux interface to use this library, using ready-to-use wine
libraries.
Is it possible, using wine libraries, to have access to functions from this
DLL?
If yes, can you tell me how?

proxy, managesieve and ssl?
Hello,
On a dovecot 2.0.14 proxy, I found that proxying managesieve works well
when using 'starttls' option in pass_attrs, but does not work when using
'ssl' option. The backend server is also dovecot 2.0.14; when using the
ssl option, it reports "no auth attempts" in the logs about
managesieve-login, and meanwhile the MUA, Thunderbird with sieve plugin,

Compiling libc++ using GNU Arm Embedded Toolchain for arm-cortex-m4
Hello,
lately, I have been thinking about how to resolve the problem with that the
program size increases enormously when including <iostream> when compiling
with libstdc++. In this library, in <iostream> there is a static object
__ioinit initialized like so:

// For construction of filebuffers for cout, cin, cerr, clog et. al.

barrier and commit options?
Hello,
On my home server (Debian etch, custom 2.6.28.2 kernel), I am using ext3
for both root and /home filesystems, with barriers enabled to prevent
corruption caused by my PATA disk write cache.
Looking for a better performance, I have also set the commit=nr option
as described in linux-2.6.28.2/Documentation/filesystems/ext3.txt, so
that I now have:

Rdindex truncating titles?
When building packages these days I keep getting warnings from
"R CMD build" to the effect that INDEX is not up to date. The
INDEXes always seem to be up do to date to *me*.
Then I thought to compare the INDEX from the package source with
the INDEX in the installed package (after building with the --force
flag set).

mbox From escaping implementation ?
Hello,
I read in the wiki (http://wiki.dovecot.org/MailboxFormat/mbox) about
"From Escaping":
"Dovecot doesn't currently do this escaping however. Instead it
prevents this confusion by adding Content-Length headers so it knows
later where the next message begins. Dovecot doesn't either remove the
'>' characters before sending the data to clients. Both of these
