We''re using unicornctl restart with the default before/after hook behavior, which is to reap old Unicorn workers via SIGQUIT after the new one has finished booting. Unfortunately, while the new workers are forking and begin processing requests, we''re still seeing significant spikes in our haproxy request queue. It seems as if after we restart, the unwarmed workers get swamped by

hello, I am now develloping an embeded decoding system for flac.I have a problem about the format of the rice coding: the residual begins with : 01 01 08 0C the first two bytes are the warmups, the prediction order is 2. and the 080C is the following: 00 0010 0000 001100 the first two bits mean: residual coding method is partitioned rice the following four bits mean: the partition order is 2 ; the following four bits mean: the rice parametre is 0; then, accdoring the ["k" z...

And warmup samples will be (17 - wasted_bits) bit. Voila, this was the source of all my frustration, sync problems and who knows what. My decoder now works correctly for files encoded with the default settings. Are there any decoder parameters I can set to get an encoded file using as many "features...

Hello you all, this is my first time on this forum because I recently started to learn this exciting "new" language and Frame stuff... anyway, I used to have Ruby 1.8.2 installed with Rails and I wrote some warmup applications on these. Yesterday I decided to update my Ruby and Rails... about 4-5 hours later I finished... it wasn''t easy but what is.. right? so I changed many things and finally everything seemed to be working ( my old applications! ) I created a new app with this new environment...

...actually demanded color. my last two laser printers have been Brother black&white all-in-ones ("MFC"). *VERY* cheap per page printing costs, even if you use Brother brand toner cartridges. They make useful copy machines, they are fast (22 page per minute, very short first page warmup). The newer one we now have does double sided scanning, and double sided printing. Both of these are ethernet/network printers. decent linux support for printing. the scanner function can direct email scans in PDF or JPG format, so there's no need for linux drivers for scanning. I h...

...RICE PARTITION SIZE: In a zero-partition-order Rice block, the documentation says the number of samples in the partition is equal to the frame's blocksize. Surely this should be equal to the frame's-blocksize-minus-the-predictor-order, since we shouldn't need to encode residual for the warmup samples? Thanks in advance!

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
