Poof

We're off, we're off for a quick trip to
The place where we did growing do
Returning in a single day
All the more with VoIP to play
Otherwise Mundane

Strange that the heart leaps
When a beautiful girl
Says something otherwise mundane
MythTV fixed (Missing kernel support for the OSS PCM API)
Written by
on
in
Tuxedo.
Turns out the MythTV failure was due to missing the OSS digital data interface in the Alsa module of the kernel (PCM), Myth was crashing in the middle of trying to work with the /dev/dsp interface without it. The card has again changed it's colour settings, but no big deal there.
Only major fallout still ...
Physical and Intellectual Depth (And the last paragraph of the somewhat reworked Abundant and Refined Depth section)
Written by

in
Design Theory.
Editing mostly today, though I did finally force myself to sit down and write something, even if it isn't particularly well written or long. Anyway, for the rabid design theory fans, here it is...
Designers often focus primarily on one of either abundant or refined depth. You will often see discussions of âtextural richnessâ of ...
Party of Loons

Those who are awake shiver
As the grey idealogue
And his party of loons
Lead the sleepers astray
Lure a country back
To darker days
Curiouser and curiouser with Asterisk manager interface (pyst doesn't seem to realise that there are event-generating queries)
Written by
on
in
Snaking.
Can't sleep, so spending more time with the manager interface. Interestingly, it seems that pyst has a fairly low-level assumption that just doesn't match the manager interface: namely that all events should be dispatched asynchronously to registered handlers. The problem is that certain actions produce a response, then a sequence of events in order that ...
Retrieving information from the Asterisk manager interface (Again, using pyst)
Written by
on
in
Snaking.
A somewhat shorter task here. Imagine for a moment that you want to be able to list the currently available SIP peers (in a web-site front-end, for instance). The manager interface can run any Asterisk command-line-interface command, but how do you get the results of that command? It's not exactly obvious, but this little recipe ...
Using Asterisk's manager interface to generate calls (From Python using pyst)
Written by
on
in
Snaking.
This is not a deep and profound project, it's a quick "hello world" example script that allows you to generate a call via Asterisk that connects a SIP URI to a particular extension in your call plan. You could use this as-is to create a phone survey or similar system that connects a user to ...
Minor tweak to the kernel a bad idea (ztdummy non-functional, whole system gone for a bit...)
Written by
on
in
Tuxedo.
Woke up this morning to try the results of last night's last kernel recompile. I wasn't able to get zaptel running, and have been noticing that the system clock is going wildly out of sync (despite ntpd running), so I turned off the preemptive kernel switch. Oops. Every loadable kernel module became non-functional. Rebuilding the ...
Housekeeping is dangerous (Accidentally blow away my only working kernel's source directory...)
Written by
on
in
Tuxedo.
I ran out of disk space on my "old" drive (which is where my home directory and all non-multimedia files go), so I went through and killed off the various system directories from my old Linux install (I run from the new disk now). Unfortunately, I didn't remember that /usr/src contained the last working Kernel ...
