Job openings as a virtual machine backend engineer - Qualcomm (Raleigh, NC)
Hi John,
I was posting the position on behalf of another team within my group,
DCG. The scope of the work is fairly broad and is closely related to
the type of work we do with LLVM, but I don't believe the potential
candidate will work directly on LLVM (at least that's not the immediate
plan). I apologize if I've somehow misused the mailing list; that was
certainly not my

Hello Jean-Marc,
Below are the results that show test_unit_dft passes, but
test_unit_mdct fails (only for nfft=480, 960, 1920)

Hello Jean-Marc,
Yep, that was it.. with your patch, test_unit_mdct passes for all nfft.
So, what you do you suggest the next step here is?

Make check failure on clone from 31 January
Hi,
Apologies if this is a known issue, but running make on revision e3187444692195957eb66989622c7b1ad8448b06 fails one of the tests when using fixed point configuration (floating point is ok) on my linux x86.
Note that libopus1.1, as extracted from the tar ball, is OK.
Specifically, the tests that fail are in celt/tests/test_unit_mdct:
nfft=32 inverse=0,snr = 85.341197

What is cast telling me?
Hi,
What is cast telling me when it says the following?
Aggregation requires fun.aggregate: length used as default
What is 'length'?
I've taken a small subset of data and wondered what EnTime vs
ExTime might look like. cast is kind enough to give me a table but I
don't understand the values in the table. They seem to sum up ro be
the same as the total dimension of the data

testenc and snr calculation
Hi all,
I'm new to the group. I'm looking at the speex code with an eye towards
maybe helping out with either codec optimization or fixed-point
implementation, The SNR calculation in testenc.c and testenc_uwb.c
doesn't make sense to me. The code is

float enoise=0, esig=0, snr;
for (i=0;i<FRAME_SIZE;i++)

[RFC V3 7/8] armv7, armv8: Optimize fixed point fft using NE10 library
I'm trying to get these cleaned up and landed, but I'm running into
some trouble with this patch. Using commit a08b29d88e3c (July 21) of
Ne10, I'm seeing test failures for 60-point FFTs:
nfft=60 inverse=0,snr = -3.312408
** poor snr: -3.312408 **
nfft=60 inverse=1,snr = -16.079597
** poor snr: -16.079597 **
All other sizes tested appear to work fine (84 to 140 dB of SNR). This

Self Calling test
I've had slew of problems with my Bell Canada Single Number Reach (SNR)
dropping in the past couple of months. Another outage Monday for
several hours has me wondering if there's a way to
1. Make a call out of my system via a PSTN back to my SNR line, say
every 30 minutes (this I'm sure is easy enough via the call
file...however...)
2. Track the outgoing call and match to an

Neat way of using R for pivoting?
Hi,
I'd like to use R to do what excel pivot tables do, and plot results.
I've never used R before, and I've managed to do something, but it's quite a
lot of code to do something simple. I can't help but think I'm not "Doing it
the R way".
I could be using R for the wrong thing, in which case, please tell me off.
I was hoping something like plot(by(t,

recode categorial vars into binary data
Dear R-List,
I would like to recode categorial variables into binary data, so that all values above median are coded 1 and all values below 0, separating each var into two equally large groups (e.g. good performers = 0 vs. bad performers =1).
I have not succeeded so far in finding a nice solution to do that in R. I thought there might be a better way than ordering each column and recoding the

Hi,
Can you apply this change to the MDCT test and run it again. See if more
(all) sizes pass. Given the results, I strongly suspect an overflow.
