FW: Re: Problem with Blackfin assembly optimizations -- bug in fixed_bfin.h?
Hi Jean-Marc,
I did some further checks with 1.2 beta 3:
The problematic function is DIV32_16 inside fixed_bfin.h. When I comment it out (i.e. replace it by the generic version of the routine), the quality improves significantly. Nevertheless, there is still a horrible distortion when there is some overdrive/saturation in the input signal. For me, it looks like there's an instable filter

locking and gfs
Hi there,I run samba as a PDC and tried to make this PDC high available with
redhat cluster suite and gfs. I experienced the following problem while
doing this:
If I set the option locking = no in smb.conf it takes about 4 minutes to
copy a file of 1GB size. If I set locking = yes it takes about 1 hour. Im
not sure if locking = no sets locking off for all locking options. At least
I need locking

FW: Re: Problem with Blackfin assembly optimizations -- bug in fixed_bfin.h / resampler saturation???
Hi Jean-Marc,
didn't get a reply to my last post (see below) -- do you have no idea what happens here?
After some more tests, I disabled the DIV32_16 Blackfin optimizations and now get good quality on the Blackfin. But when I have overdrive on the input, things become very bad -- I'm not sure if this is really a filter stability issue like I wrote some weeks ago.
I use the speex

Fixed Point on wideband-mode: Single Frame loss on 2000 Hz sine causes "freak off"
Hi Jean-Marc, all,
I didn't get any response to my issue up to now and would like to now if anyone can reproduce this behaviour and if there is some idea what happens. I am willing to fix this issue, but because I do not know the internals of speex, I need some advice on how to proceed...
best regards,
Frank

What happens if you change that line:
if (cumul_gain > 262144)
to use a smaller value? What value works OK (if any)?
One more thing, when things go wrong, do they eventually go back to
normal or does the codec never recover? It's unavoidable that the audio
goes bad for a short period of time because of the long-term predictor.

Hi Frank,
Sorry, I *do* care about the problem and just happen to be overworked at
the moment. What I suspect is that the pitch gain gets close enough to
unity that the loss makes it bust. Did you test with the floating-point
code?

Hi Jean-Marc,
yes, problem exists in narrowband-mode, too.
I already twiddled with max_gain, but did not have real success. I changed line 337 of ltp.c (function pitch_gain_search_3tap_vq)
if (sum>best_sum && gain_sum<=max_gain) {
to
if (sum>best_sum && gain_sum<max_gain) {

Fwd: Re: Fixed Point on wideband-mode: Single Frame loss on 2000 Hz sine causes "freak off"
Hi Jean-Marc,
dBFS means dB relative to digital full scale. In other words: a sine value of -42 dBFS will, on a 16 bit PCM signal, swing between 131 and -131 only (16384 * 10^(-42/20))
So we are far below +/-8000.
At the moment, I'm out of ideas how to debug systematically. That even very small rounding errors alter pitch values fundamentally makes the situation worse for me, because it

xen-create-image: command not found?
Hello,
after I fixed one problem, the next one raised up. I am trying to create a guest domain. I specified the configurations in /etc/xen-tools/xen-tools.conf and I ran

the output is: sudo: xen-create-image: command not found

O.k., some more info:
I just tested bandwidth widening to fix this. But I need to go to gamma values below 0.9 to become stable -- clearly too much widening, I think.
I looked inside the Levinson-Durbin algorithm next. The lines
#ifdef FIXED_POINT
r = DIV32_16(rr+PSHR32(error,1),ADD16(error,8));
#else
r = rr/(error+.003*ac[0]);
#endif
look interesting. While for floating point,

Fwd: Re: Fixed Point on wideband-mode: Single Frame loss on 2000 Hz sine causes "freak off"
Hi again,
I tested lower cumul_gain limit values. In fact, I reduced the value to 240000, 230000, 220000, ..., 20000, 10000, 5000, 2000, 1000, 500. (quality 7, complexity 2)
For input signal 2000 Hz, the values 190000, 130000, 60000, and 1000 look o.k., all others don't. For 500, the (zoomed out) waveform shows some kind of amplitude ripple -- i think, this value is definetely too low.

v.1.2.4 deliver maildir quota does not work
Hi,
I'm using deliver for storing new mails (nfs).
Since v.1.2 deliver does not reject mails if over quota (maildir quota).

[LLVMdev] LLVM for heterogenous platforms
Hi llvm,
it's for sure an obvious idea to use llvm as IR for heterogenous
platforms (e.g. CPU+GPU).
In theory someone could write plain C/C++ code, which by clang is
translated to llvm-IL and then
together with JIT-backends packed in an appropriate executable. Thus all
the limitations
and hassles of openCL or CUDA could be avoided. I wonder if there
already is a related project?

sparse files patch question
Hello,
i just came across the sparse-block patch.
i`m using rsync to store vmware vmdk virtual disks to a zfs filesystem.
vmdk files have large portions of zeroed data and when thin provisioned (not being used yet), they even may be sparse.
on the target, after writing to zfs the zeroes are always efficiently stored/compressed, i.e. they take no additional space on zfs.
is this patch worth a

is it possible to get rrsync with the "--delete" option working?
Or is the rsync server really started unidirectional in this special scenario?

R squared from cv.lm
Hello,
I used the cv.lm function to validate a linear regression model
fit<-lm(y ~ x1+x2+x3+x4+0, data=mydata) without intercept
I tried to validate the model by performing a leave one out cross validation
procedure usinfg the cvlm function:
CVlm(df=mydata, fit, m=196)
But how can I get the adjusted R? from the output of this function.
Or is there any other function to
