Hello from Khazakstan, sending in the divers

If you watch only one video from LCA2005, make it the mad South African’s presentation.

Mark Shuttleworth is very, hah, down-to-earth, informative and funny. Classic lines include (on Soyuz landing simulations) “The sea was very calm that day <voice accent=russian>No problem, we’ll put in some divers to make it rough</voice>” – he learned Russian as part of becoming a fully qualified Cosmonaut, and reckons it’s very hard to do on a hangover – and (quoting a fellow cosmonaut on what happens to a Soyuz capsule when the parachutes are deployed out the side) “Sh!t, that wasn’t in the simulator!”

Sundry quotes about molten metal running up the windows during descent (before the windows themselves blistered and fogged) and surreptitiously-installed VoIP software make this an unmissable in-depth edutainment session.

new life for an old (FTX) PSU, improved life for one human

the LEDs on this 5m strip happen to emit light centred on a red that does unexpectedly helpful things to (and surprisingly deeply within) a human routinely exposed to it. it has been soldered to a Molex connector, plugged into a TFX power supply from a (retired: the MoBo is cactus) Small Form Factor PC, the assorted PSU connectors (and loose end from the strip) have been taped over. the LED strip cost $10.24 including postage, the rest cost $0, the PSU is running at 12½% of capacity, consumes less power than a laptop plug-pack despite running a fan. trial runs begin today.

I have a LibreOffice Impress slideshow that I wish to turn into a narrated video. 1. export the slideshow as PNG images (if that is partially broken — as at now — at higher resolutions, Export Directly as PDF then use ‘pdftoppm’ (from the poppler-utils package) to do the same). 2. write a small C program (63 lines including comments) to display those images one at a time, writing a config file entry for Imagination (default transition: ‘cross fade’) based on when the image-viewer application (‘display,’ from the GraphicsMagick suite) is closed on each one; run that, read each image aloud, then close each image in turn. 3. run ‘Imagination’ over the config file to produce a silent MP4 video with the correct timings. 4. run ‘Audacity’ to record speech while using ‘SMPlayer’ to display the silent video, then export that recording as a WAV file. 4a. optionally, use ‘TiMIDIty’ to convert a non-copyright-encumbered MIDI tune to WAV, then import that and blend it with the speech (as a quiet b...

boundaries

pushing the actual boundaries of the physical (not extremes, the boundaries themselves) can often remove barriers not otherwise perceived. one can then often resolve an issue itself, rather than merely stonewalling at the physical consequences of the issue.
