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

MythTV fixed (Missing kernel support for the OSS PCM API)


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 ...

Physical and Intellectual Depth (And the last paragraph of the somewhat reworked Abundant and Refined Depth section)


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 “textural ...

Curiouser and curiouser with Asterisk manager interface (pyst doesn't seem to realise that there are event-generating queries)


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 ...

Retrieving information from the Asterisk manager interface (Again, using pyst)


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 ...

Using Asterisk's manager interface to generate calls (From Python using pyst)


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 ...

Minor tweak to the kernel a bad idea (ztdummy non-functional, whole system gone for a bit...)


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 ...

Housekeeping is dangerous (Accidentally blow away my only working kernel's source directory...)


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 ...
