...omputation. However, when I finally inspected the source code for apply, it appears that the core computation is a simple loop as well. What am I missing ? Why the often found advice to use apply() instead of loops and the actually observed empirical speedups on many tasks ? Thanks in advance for demystifying, Markus [[alternative HTML version deleted]]

I understand that the capture/playback signals need to be sync'd for an AEC to adapt. I'm a little bit confused on the requirements of synchronous sampling between the near end (mic/speaker) and the far end (phone line). I have an embedded DSP system with mic and speaker getting 1msec packets containing 8 samples. We can watch the DSP and ISDN clock frames drift and every few minutes we

Hi Folks, Apologies in advance for the blatant advertisement. Just thought you might be interested in our new regional Ruby/Rails conference series.

Hi, I have two data sets; one is a population and the other a sample of that population. I am trying to plot both on the same trellis display. # Example data set with two numerical attributes and two categorical pop <- data.frame(var1=rnorm(2000, 2000, 500), var2=rnorm(2000, 2000, 500)) cat<-(runif(2000)<=.5)+0 for(i in 1:length(cat)){ if(cat[i] == 0){ pop[i,"cat1"] =

The EuroLLVM'18 Developers’ Meeting relies on volunteers to keep things running smoothly. Moderators are critical to this as they keep speakers on track and facilitate Q&A after the talk. I’m looking for community members who would be attending specific talks anyway, to volunteer to moderate the sessions. If you are interested in volunteering, *please respond to this email with your first

Hello LLVM Developers! Last year, the LLVM Foundation sponsored a booth at the Grace Hopper Conference. I had 2 amazing volunteers from the community, David Blaikie and Anna Zaks, help me spread the word about LLVM, compilers, and open source. It was a great experience and we are hoping to repeat this at the upcoming 2018 Grace Hopper conference in Houston, TX on September 26-28. I’m looking

Guys, For those of you not party to the original email exchange, this is about how we can aggregate bandwidth across both rails of a dual-rail IB cluster using current lustre/LNET (i.e. before we have implemented transparant LNET support for failover and bandwidth aggregation across multiple networks). The following 2 points are fundamental - everything below is a direct consequence... 1. LNET

Hi,all I have tested AEC on files, it works well.I have some files,one is echo file, others are echo-added files(an origin file adding echo at different delay,such as 20ms,40ms...120ms,140ms).AEC do wonderfully on those files except echo added at 140ms-delay. But ,when i use AEC in my voip project, it does feebly. Who can give me some hints why caused this.How long can sound be picked up by

Hi, there, I am working on a project on software control flow checking, which instruments a program to check if the control flow at runtime matches the control flow graph computed at compile-time. My instrumentation process has to make use of control flow information, including as control flow graph and dominator/post-dominator trees, so it is better part of the compiler. On the other
