I'm Leigh - a freelance web-developer that specialises in PHP with a background in C, with an extensive experience in Drupal content management system (10 years and counting!) . Also known on drupal.org as dgtlmoon
This blog is a dumping-ground for research, thoughts and developments.
essentially all i'm doing is posting some images under a certain tag name and then adding some notes to certain regions of those images, seem s to work pretty damn well, saves all that annoying point-at-smudgy-spot-onthe-screen kind of stuff.
Bought a new digicam after being withone for a year or two now.
Which is the Canon Powershot SD430, No idea what "Digital elph" means but it's on the manual cover. My previous camera was the canon powershot A10 (the very first of the powershot range).
Canon IXUS Wireless Powershot SD430 (hows that for a model number!), seems to work ok, will have a bit more of a play with it and see what i can discover, I've got no idea how to use the wireless interface for it, I plugged the USB adaptor into my laptop but i didnt register as much so who knows.
One thing that is immediately obvious with this camera is
It's size - small, very tidy
Good-enough lens quality
Some smarts about organising files on the SDCARD, such as creating sub-directories by date
Remarkably easy to navigate user interface
Very quick to fire off to the next shot
Very quick start-up time
under linux it shows up as
Bus 003 Device 002: ID 04a9:3131 Canon, Inc.
However the Canon IXUS does not register as a generic SCSI device which is a bit of a pain, BUT do not fear, theres always gphoto2.

Downloading 'theme.dat' from folder '/special'...
Saving file as P1000019.JPG
The Canon does movie mode, which saves as an .AVI file but there seems to be a little bit of background noise, will have a few more attempts at it, also you cant chang the zoom status while filming!
interestingly enough, theres a group of hackers working on somethis called the LIXUS project which is all about getting a running linux kernel on the canon ixus which sounds like a lot of fun, looks like they've got a command prompt so far, not sure if it still takes photos!
An annoyance abuot the SD430 is the USB wireless adapator needs its own powersource (whats the point!) but i guess this is all pretty new kinda tech so needs to be ironed out. Turns out the wireless is 802b11
Video output (in .AVI format) is converted to MPEG locally with ffmpeg, which is in debian apt sources (im on testing atm), the camera done 30FPS @ 640x480, reduced it to 15FPS @ 300x320 and the output was around 163MB for 54 seconds worth of video, mpeg'ed that was converted to 9MB
Something I wrote for a small project, initially designed to listen my radio scanner via /dev/dsp and record when it hears something, this uses python and some threads to launch instances of 'lame' encoder and then insert them into MySQL.
The app has a threshold for incomming sound levels and starts recording when the threshold is reached, there is also a setting for time-distance between hearing things so you dont end up a billion little mp3s because the audio is dropping out, just a nice long mp3.
Recently I purchased a DreamHost account, seems to go pretty except for a few small things.
Bottom of this article is my full PHP5+IMP tar ball ready for download so you can get going with the good stuff.
Annoyances with dreamhost..
Dreamhosts's default PHP5 does not have IMAP extention installed
You gotta pay extra per month for SSL portforwarding to your IP address (what a jib!)
It's a cheap hosting environment so no they dont let you just edit /etc/php.ini and add lib_imap.so, as theres lots of nasty php scripts out there that will do all sorts of terrible things to their PHP 5 / IMAP servers. - so you gotta compile your own PHP..
Dreamhost have their own webmail, so this isnt about installing their existing webmail on dreamhost
