(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, or some new

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). -------------- next part -------------- A non-text attachment was scrubbed... Name: fixed.patch Type: application/octet-stream Size: 2503 bytes Desc:

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

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". - What is

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) > summary(fit1) FITTING OF THE DISTRIBUTION ' gumbel

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){ dgamma(x[2],shape=2,scale=1)*dnorm(x[1],0,.5) } liklihood =

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 is

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: AIC(mymodel) # numeric(0) Thank you! -- Dimitri Liakhovitski

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
Hi, 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
