opus-1.3.1 patch for ARM Cortex-M4F (single precision)
The patch prevents KEIL MDK compile warnings, like:
warning: #1035-d: single-precision operand implicitly converted to
double-precision
Actually ARM Cortex-M4F has only a *single precision* (float) FPU.
It's suit for all platforms.
See the comment at the begin of patch file.
Sincerely

Benchmarks on Pi
I have run a few more test at different bitrates and 1.1 is looking even
worse in terms of speed compared to previous versions.
I have shared a google sheet which has the raw data and charts for 6,16 and
32 kbps. Unfortunately you cannot show proper error bars on Google sheets
but the standard deviation is in the data if you want to look. You can see
that the profile for 1.1 is a lot different

Benchmarks on Pi
Hi All,
What would be interesting would be a plot of complexity versus subjective or
object audio quality.
I've not had a chance to look at the new analysis code in 1.1 so maybe in
the case of a 6kbps compression you could clarify what decisions would it be
making that would justify the extra complexity?
Best Regards
Cliff Parris

Interesting behavior of lm() with small, problematic data sets

Almost.
All the results in the OP's summary are reflections of finite precision in the analytically exact solution, leading to residuals smaller than the double precision limit. The summary is correctly warning that it's all potentially nonsense, and indeed the only things you can trust are

performance with huge files
Hi all,
I'm working with some very large files, 500GB or thereabouts, using
rsync 3.0.7. I'm not familiar with the internal operation of the
rsync protocol, but I've read a few old posts that suggest there may
be ways to improve performance.
Can anyone give me pointers to config changes or patches that might
help reduce the CPU burden when working with such large files ?
Thanks in

Dividing a pixel image into factors - (cut.im(), cut.default())
Hi,
I have a numeric pixel image which I would like to divide into factors
for analysis in Spatstat. I have found that I can use cut.im() function
to divide the range of pixel values into a series of equal length
intervals (e.g. if my pixels values range from 0 to 60,
cut.im(X.im,breaks=2) will produce two factors one containing pixel
values 0-30 and one containing pixel values of 30 - 60, or

Plotting a large time series
I have a time series with many millions of points.
Each point is of the form (time, value) but where the value is 0 there is
no record - ie the data set is sparse.
If I plot this using plot(myData) I get a correct plot going from time 0 to
time 7x10e7.
Given that there are many millions of points (it's not *that* sparse), this
looks very busy.
But if I attempt to plot this as a line -

Strange "no-echo" in place of "slave"
The first of Suharno's examples can be viewed that way, because R under ESS is not a "slave" in the technical sense, just a situation where you do not want keyboard input to be echoed. "Non-echoing" might have been better language though.
The 2nd example really is of the master/slave variety, and to my knowledge nothing to do with echoing, so looks like a

Interesting behavior of lm() with small, problematic data sets
Indeed (version-specific).
With R 3.4.1 on linux, I get coefficients and residuals that are
numerically exact, F-statistic = NaN, p-value = NA, R-squared = NaN, etc.
All of which is what ought to happen, given that the response variable
(y) is not actually variable.

Intel Xeon and hyperthreading
Another question some of you may help me make decisions on. I've been
doing some reading that indicates that having HT turned on in this dual
xeon machine might actually slow down the computing process rather than
speeding it up. I rebooted this a.m., and turned HT off, just prior to
my main application run. One thing that might be of note, this
application is using OMP for utilizing

Centos 5.8: starting firefox-16.0.1 kills X
This just started happening this evening.
a little history:
way back last year, or thereabouts, I posted about a weird problem I was
having. over the course of 2 or 3 days I figured out how to fix it, but
not what the cause was. the fix amounts to navigating to my user's
.local/share/mime directory and removing the file named "globs".
So, back in the present: this evening that

IAX2 * -> * handoff
Hey All,
I am setting up a network of Asterisk servers using IAX2. I am wondering
if it is possible to disable the handoff feature?
At the moment I have 4 asterisk machines, 3 are at SOHO offices and 1 is
centrally hosted in a data centre. In addition the central machine has
an IAX2 link to a VOIP provider (and might be set up with more in the
future). All calls are routed through that

glmnet_1.5 uploaded to CRAN
This is a new version of glmnet, that incorporates some bug fixes and
speedups.
* a new convergence criterion which which offers 10x or more speedups for
saturated fits (mainly effects logistic, Poisson and Cox)
* one can now predict directly from a cv.object - see the help files for cv.glmnet
and predict.cv.glmnet
* other new methods are deviance() for "glmnet" and coef() for
