One of the banks I deal with uses one-time transaction numbers
which they send in bulk by paper mail every now and then. (Pity that the local
banks aren't as enlightened...)
The notion of "TransAction Numbers" I like, carrying the paper slip
I don't - because paper encrypts so very badly and I'm lugging
my Palm with me all the time anyway.
gocr takes care
of the OCR, and generally works fine but BSTS...if comparing
two sheets of meaningless numbers wasn't so ridiculously, mind-numbingly, dull.
Can't have that.
So I had to look for a cheap, quick and dirty solution for that not-quite-problem, and after ten minutes I had it: espeak.
It's a fairly simple speech synthesizer, which unfortunately insists on
pronouncing numbers as numbers, not individual digits, but a
trivial half-line of perl data massaging took care of that.
Sure, espeak sounds like a post-lobotomy HAL 9000 with a hangover, but hey,
it makes sanity-checking of the OCR results a lot faster and easier.
(Enlightened) Laziness is a virtue :-)

Conny has left the building. Still in transit: yesterday BNE-AKL, a few hours
in Auckland, then AKL-LAX and many boring hours to be whiled away
in Los Angeles. Now she's close to boarding her last flight, LAX-PHL, and
should arrive back home in Philadelphia tomorrow morning local time.
And it's pretty empty in this here house, without her around.

This human universe is a mess, what with the authoritarian assholes
always lusting after (& usually getting) control, and I for one
am quite sick of it.
Therefore Tor appeals to me, a lot: no
logs. decent crypto. grass-roots. hard to subvert completely. Good.
So in an attack of unwarranted altruism
I'm doing my tiny
bit to improve this bloody place. (mind you, with limited bandwidth and not
as an exit router just yet, cause I want to monitor that experiment a bit
longer before I extend the service)
Update (Sun 08.08.2010 15:46):
Just like owl - who knows how to spell its name: "wol" -
wol.snafu.priv.at doesn't know much. More specifically it knows nothing
about whom it is relaying Tor traffic
Since today, wol also serves as an exit relay for a small number of well-known services.

I don't get it why people pick an Arduino
for their electronics projects:
they're expensive, fat gadgets in all senses of the word fat: bootloader,
IDE, board size, dev environment complexity...
A $5 PIC can do the same things and exposes you properly to what you're
doing - preferrably in assembler, not C. Sure, large projects are better
coded in C - later on, after you've mastered the low level;
until then there's nothing better than assembler for learning how
a computer works.

born sometime in 1972
Austrian by chance, now
living in Australia by choice
classic hacker in
appearance and habit
graduate of the Technical
University of Vienna (with the degree of
"Dipl.-Ing. Tech. Math." which is somewhere between a "masters"
degree in computer science and/or mathematics and a full PhD) and
more recently of Bond Uni
(with a PhD).
unix/linux sysadmin, security consultant, developer etc.
clearly not my full resume; if you need one
and lots of other things no one cares about to know...but if you do,
have a look in the interests section.
Update (Fri 06.08.2010 15:23):
I suppose it was time for a new photo, and Conny delivered a nice one :-)

Here are some shots of the progress of the Wheely King
towards a decent-strength bumper:
This 2008 version in metal didn't last a day (or more precisely the
epoxy resin didn't hold it together long).
Shapelock is a
pretty cool stuff: malleable from 60°C upwards and pretty strong when
cooled down. This metal-plus-plastic bumper survived a good
two years and quite a few rammings caused by a certain Kid Who
Loves Full Throttle ;-) - but eventually the metal supports
succumbed to said kid (the shapelock parts were still fine).
And this is the latest version: a bumper make from shapelock only, no more
batteries high up but shortened packs low and on the side of
the frame, a fully locked rear diff, a grease-and-blutack-LSD in front,
and decent tires on beadlocks. Looks dud but it works pretty well now :-)
