Interesting results, thanks.
(OTOH, GCC 4.6 was released ~4.5 years ago, so it would be also
interesting to test it on newer compilers - GCC 4.9.x or 5.x,

Yes, but the code in FLAC__fixed_restore_signal() is (ignoring identifier
name differences) identical to FLAC__fixed_compute_residual(),
Maybe I should just publish my micro benchmarking code as part of the

PATCH for fixed.c/fixed.h
Tests show that FLAC__fixed_compute_residual/FLAC__fixed_restore_signal
are slightly faster when flac_restrict modifier is added to their arguments.
(Encoding speed increase for flac -8 is about 2%. The difference is
not very big yet measurable).

Against 0.9 or CVS? While this clearly fixes a bug, 0.9 still dies
for me.

Re: Reg. FLAC decoding
Sorry for the delay in getting back to you., I was working on something
else and just now got FLAC to work.
Ok., FLAC files are playing now :) Cheers. There is a slight noise
happening in the background., which i'm figuring out. I hope that it'll
be solved soon. However, i wanted to know if there are any ARM specific
optimizations that can be done. The processor is a 166MHz processor. Do

I don't think so. 0.9 works fine on i386 (little) and sparc (big),

Altivec, automake
I think I've gotten FLAC__lpc_restore_signal() about as good as I'm going to
get it.
Here's what I have:
-a new file, lpc_asm.s, which has the assembly routines
-changes to cpu.h, cpu.c, and stream_decoder.c to enable them
-changes to configure.in to support the new cpu stuff
-a preliminary Makefile.am
-maybe something else I'm forgetting
Now automake complains that configure.in

0.9 problems
Problems in FLAC 0.9:
- On alpha, flac immediately dumps core for both encoding and
decoding (FreeBSD/alpha).
- The distribution Makefile.in files haven't been generated with
"automake --include-deps". The resulting Makefiles aren't fully
portable; in particular they break with BSD make. In the future,
care should be taken to use "--include-deps".

standard error very high in maximum liklihood fitting
Dear all,
I have been trying to fit my data (only right censored) with gumbel distribution using fitdistrplus. I am getting very high standard error. I have been wondering why.
The followings are the outputs:
fit1=fitdistcens(dr0, "gumbel", start=list(a=99, b=0.6), optim.method= "L-BFGS-B", lower = 0.0, upper = Inf)

anova or liklihood ratio test from biglm output
(Sorry if this is a repost, I got a bounce reply from the r-help server)
Hi,
I’m using the biglm() function to create some linear models for a very
large data set than lm() can’t fit due to memory issues (the problem is
with the number of interactions, I can fit the main effects model)
I need to determine if the 2-way interactions are necessary or not. Ideally
I’d like to use anova() to

R Crashes on certain calls of Adapt
I'm having trouble with adapt. I'm trying to use it in a Bayesian setting,
to integrate the posterior distribution, and to find posterior means. I
tried using the following script, and things went ok:
data = rnorm(100,0.2,1.1)
data = c(data,rnorm(10,3,1))
data = data[abs(data)<2*sd(data)]
prior = function(x){

channels VHF/ HF radio in asterisk
Hy,
I have a network with WIFI communication and VHF/ HF channels.
I have integrated asterisk in the network using SIP, ZAP and IAX2
channels for WIFI communications, but I don't Know How I could integrate
the VHF/ HF channels.
I have heard speaking about app_rpt project, but I don't Know very much
about this.
Could I integrate VHF/ HF channels with this application? if the answer

Calculating AIC for the whole model in VAR
Hello!
I am using package "VAR".
I've fitted my model:
mymodel<-VAR(mydata,myp,type="const")
I can extract the Log Liklihood for THE WHOLE MODEL:
logLik(mymodel)
How could I calculate (other than manually) the corresponding Akaike
Information Criterion (AIC)?
I tried AIC - but it does not take mymodel:

Grouped Logistic (Or conditional Logistic.)
Hi,
I'm not sure of the correct nomenclature or function for what I'm trying
to do.
I'm interested in calculated a logistic regression on a binary dependent
variable (True,False).
There are a few ways to easily do this in R. Both SVM and GLM work easily.
The part that I want to add is "group wise" awareness. So that the
algorithm computes the coefficients to maximize

imap indexing error when moving multiple mails

I've got an 'interesting' problem with a dovecot 0.99.10.4 setup on
NetBSD/i386 1.6ZK.
dovecot is serving imap only at the moment, using mbox format
mailboxes. '/etc/dovecot.conf' is pretty vanilla - among the modified
settings,
mail_read_mmaped = yes
maildir_check_content_changes = yes
mbox_lock = fcntl
could be relevant. Anyway - from time to time when I move a
