Can you give an example of this? Is it the case when you divide the
granulepos such that it moves to before the previous keypoint's granulepos?

Ogg index and Skeleton 4.0
...nd time" fields for that track. The duration can now be
calculated as the greatest end time of all active tracks minus the
smallest start time of all active tracks. Thanks to Benjamin for
pointing out the need for this.
* I've removed the requirement in my spec that a keypoint must index
the first keyframe in their page only, and reworded my validity
conditions.
The new spec can be found here:

If anybody thinks anything else should be added to Skeleton 4.0, please
speak up...

You are storing 1.7 million e-mails in a single mbox file. I would rather store the archive using one file per e-mail.

Right, so I could encode the offset of the first keypoint with extra
empty bytes using my unicode-style-variable-byte-encoding, in order to
remove one potential re-encode. I decided there was no reason to bother
with this, since re-encoding the index was so cheap and easy.

Dial command to connect two channels and bypassasterisk server
...d bypass asterisk server
thanks for the information Peter, its really helpful. Also I have one more question - do you have any idea how many such simultaneous calls can an asterisk server handle (say running od 2.6Ghz, 1GB Ram, fedora machine)?
Thanks,

For the record, the Skeleton 4.0, as implemented by OggIndex, currently
requires a multi-round iteration to produce. The encoder produces the
index, then shifts the file content

Asterisk download file locations
This is a request to the website manager for asterisk.org.
The build scripts for our ITSP product include the URLs to download the
Asterisk files, such as:
wget "http://ftp.digium.com/pub/asterisk/asterisk-1.2.5.tar.gz"
However, if a new version is released, asterisk-1.2.5.tar.gz is moved to
the "old" directory. This breaks our scripts until we can update them

Indexing Ogg files for faster seeking
I've developed an indexer which embeds a keyframe index track in Ogg
files. It embeds the index in its own track, so that players that don't
understand or don't want to use the index can just ignore it.
Ogg needs this to make seeking over networks faster and more efficient.
Currently we must do a bisection search when seeking, which usually
takes aound 6 HTTP requests, give or

Guest TSC and Xen (Intel and AMD feedback please)
Various versions of Linux under various circumstances select
TSC as the primary clocksource for the kernel. This is
especially true for uniprocessor kernels, but also in some
cases for multiprocessor kernels. In most cases, this
is because a processor bit (tsc_invariant? constant_tsc?)
is passed through directly from the hardware via Xen and
tested by the hvm guest and the result implies that

Quicken Accounting software.
Just a quick note for those who are interested in getting the accounting
package Quicken running under Freebsd 6 using wine, it may work with
other installations as well but I have not tried it but others may like
to.
I am very new to this so it all I have done will no doubt be considered
as quick and dirty by some but it worked for me and I am tickled pink.
Firstly, trying to run setup.exe

app_read prematurely bridges channels
Hi list,
Running Asterisk 1.4.10:
When using the M() option for Dial to execute a macro, then executing a
Read within the macro, once streaming of the audio file specified in
Read has completed, and the channel attempts to read input from the
destination channel where the macro is executed, the source channel
stops ringing/moh, and audio from the source is bridged into the
destination.

IAX2 channels denoted as '(None)'
I have some stuck channels that I think I'm going to have to bounce
Asterisk to get rid of, but am curious to know what they are and how
they've managed to accumulate. The show up with a channel identifier of
'(None)' as in the output below, and do not show up in the soft hangup
