This is the most useful netem guide I can find online. Thank you very much.

One minor difference I found was the file path
/proc/sys/net/bridge-*
does not exist on CentOS 5 and 6;

They are located here
/proc/sys/net/bridge/bridge-*
on CentOS.

Comment on Live555: Compiling with VS2008 by john-paul renno

The problem with the script is spaces in the path to compiler given in $(TOOLS32)

The win32config file must provide the path to VC in quotes if a space is present, however this is concantenated later with other variables along with the quotes. For me this concatenation of variables that were already quotes yielded invalid paths to the comiler exe.

The solution i employed was to create a duplicate variable of $(TOOLS32)
without the quotes by doing: something like this:

TOOLS32_NO_QUOTES=$(TOOLS32:”=)

subsequently i replaced all concatented occurances of $(TOOLS32) with $(TOOLS32_NO_QUOTES) and voila, each makefile was generated and executed with no problems according to the above.

PS: i used VS2010 SP1 compiler/linker.

Hi, really interesting your guide. The problem for me is that I have to use Live555 in a Qt project using MinGW.

So, how can I compile Live555 with MinGW? I’m working on XP

Thank you

Comment on Ffmpeg and Invalid Buffer Reads by Flo

Flo — Thu, 20 Oct 2011 06:19:25 +0000

Hi Tom,

sounds interesting: I’m also struggeling with read buffer problems with ffmpeg regarding live transcoding of a mpeg2 stream. Maybe this issue is also addressed with your patch.
Have you committed your changes back to the official ffmpeg sources or are your changes available (patch file)?

Comment on Etymology of “Foo” by Kevin K

Kevin K — Fri, 30 Sep 2011 01:59:23 +0000

How about the “hierarchy” of foo? You’re West Coast, right?

For some reason, I put “garply” fourth, before “quux”…

Comment on Faith vs. Hope by Beekae

Beekae — Mon, 26 Sep 2011 06:34:14 +0000

Nice article. I’ve wondered why don’t churches just focus on faith instead recently. I’ve come to the understanding that whether one has hope or faith depends on their level of maturity – not necessarily only in a spiritual sense since faith and hope can be powerful for non-Christians as well. Those who don’t grasp the power of faith enough settle for the relief from mental burdens that hope brings. Those who grasp faith a bit further, would never settle with hoping.

Even from a totally worldly practical perspective, one can see that with faith, you can focus all of your faculties and resources toward a solution but when hoping you waste much mental energy and time just consoling yourself and convincing yourself that things will be better.

Comment on C/C++: Using Bitfields Effectively by anduril462

anduril462 — Thu, 08 Sep 2011 17:35:28 +0000

Nice article, especially the race condition section. There’s one other big problem you missed though. The order of allocation of bit-fields is implementation defined, so it’s entirely possible, though unlikely, that the implementation puts the fields in some order other than what you specify. That means, for example, that Base may actually occupy bits 16-31, and your direct read from a hardware register wont work. To use this reliably, you must have a thorough understanding of your implementation (compiler, etc) and even then, it’s not likely to be portable. See section 6.7.2.1 of the C99 standard for a list of other implementation-defined and unspecified behaviors to look out for.

Comment on Faith vs. Hope by Pratap

Pratap — Sat, 27 Aug 2011 20:50:47 +0000

This article has thrown a simple but comprehensive distinction between FAITH and HOPE which was often confusing me. And when referring FAITH in the light of the Biblical versus, it was more obvious and reinstated my FAITH (not Hope!) in my understanding the subject which otherwise was of the opinion that there wasn’t any difference.

Thank You Tom! God Bless You.

Comment on How to Define NaN (Not-a-Number) on Windows by Chris

Chris — Mon, 22 Aug 2011 14:27:09 +0000

I found the following easier and independent of 32/64 bit platform issues.
It also avoids the __nan constant:

#ifdef _MSC_VER
#define INFINITY (DBL_MAX+DBL_MAX)
#define NAN (INFINITY-INFINITY)
#endif

The check for a defined _MSC_VER makes sure that the code can even
be compiled on a C99 compliant compiler or on Unix/Linux.

Comment on High-performance Timing on Linux / Windows by jgreen

jgreen — Fri, 22 Jul 2011 17:31:38 +0000

I find your article to be very informative and am trying to measure an apps perf across multiple procs. What I am unable to find or get info on is the typical value of the cpu clock id that is returned by the function clock_getcpuclockid. I’m getting negative integers but oddly enough, they are unique on the node, but identical across nodes. (i.e. cpu clock id for cpu #1/4 is the same value on node one as it is on node 12). Does this make sense to you? If so, please explain. Thanks!

Comment on Audio Resampling Using FFMpeg (avcodec) by GRR

GRR — Sun, 22 May 2011 04:40:19 +0000

Hi,

Thanks for posting the code. I have one question. Looks like av_resample API only excepts input data which is a “short” int. I have a wav file with each value being a double. Can you suggest me what I can do in this case. Can I still use the av_resample API?
