I enjoy technical challenges...if and when I succeed eventually.
This posting may be a technical challenge
for you, but watch me not care. Some of you may appreciate the
information and that's good enough for me. So, if you're interested in
homegrown MP3 music boxes, Linux on Netvistas, PIC microprocessors, RS-232,
infrared remote controls, and what an obtuse idiot I occasionally am, read on!
(As always I also hand out the involved source code, which might come handy
if you want to build something similar.)

A federal judge in Vermont has ruled that prosecutors can't force a
criminal defendant accused of having illegal images on his hard drive
to divulge his PGP (Pretty Good Privacy) passphrase.
U.S. Magistrate Judge Jerome Niedermeier ruled that a man charged with
transporting child pornography on his laptop across the Canadian
border has a Fifth Amendment right not to turn over the
passphrase to prosecutors. The Fifth Amendment protects the right
to avoid self-incrimination.

I have a new car (new for me, that is; June 2000 was its birthday).
As you can see the rego is "554 JTH", which I've decided stands
for "Just Tell HAL":
the car has a few very stupid gimmicks.
The first and foremost is HAL, the climate control system. It's a completely stupid FPOS and works only
properly when lobotomized (aka non-auto mode).
Asking gargle about HAL is enlightening.
Here's a pic of HAL de-brained, which is actually part of the major
disassembly job that is required to install a car radio. HAL lives in
that innocuously looking top box with the LED blinkenlight panel.
The radio install was...painful. First I couldn't get a matching wiring
harness and had to solder up my own (cursing the idiots at VDO for mislabelling
the ISO connector pins in their excuse for a manual), then I needed to
make an antenna extension (the previous radio, a clarion with cd but no mp3
capability used an odd diversity antenna setup: there's two coax cables in the
car, no idea if both are active - anyway, the antenna is in-glass, performs
ok and one of the coaxes worked). Then of course the dismantling and
reassembly job times two (because I ripped it apart yesterday but couldn't
finish and put it back together then), plus trying to figure out where
to put the UHF radio later on. Anyway, we have sound. And I'm in control of it.
The next gimmick I could do easily without, thank you very much, is
the hill-holder. No, stupid car, I want you not to keep
applying the brakes after I lift my foot and until
I let the clutch go, I want you to roll. Roll, goddammit!
ROLL! Do I have to push? ROLL!
I can hill-start on my own (and without handbrake), and if I wanted
such gadgetry I would have bought a bloody automatic! I don't and so I didn't.
Most of the other features are quite ok. What wasn't ok was that some
idiot mechanic, wannabe or detailer had disconnected the fuel pressure
regulator vacuum hose from the inlet manifold and left it to dangle in the
wind: idle a tad high and slow to return on stopping, lousy starting
behaviour. I found and fixed the dangling hose when hunting
for the fuel filter (which this oz model apparently didn't get? Silly,
as if this place wasn't dusty and dirty...
And I had bought a replacement filter already, well maybe I'll retrofit it)
in order to figure out the odd starting behaviour.
The 2652 pages of factory service manual that I sucked earlier came
already very handy for figuring out where the hose should go. The result was
immediately improved starting and lower/better idling. Very good.
As to HAL, well, at least there is the "Lobotomy, Now!" button.
BTW, this is how the system is supposed to work;
a fairly rotten setup if you ask me. Consequentially, this is how it
actually works out for
most Outback/Legacy/Liberty/Forester owners:
The Outer Limits Control Voice...
"There is nothing wrong
with your ACC. Do not attempt to adjust the settings. We are
controlling operation. If we wish to make it warmer, we will bring up
the heat. If we wish to make it colder, we will set it to 65. We can
reduce the fan to a soft breeze, or sharpen it to full blast. We will
control the vents. We will control the AC. For the next hour, sit
quietly and we will control all that you feel and hear. You are about
to experience the awe and mystery which reaches from the inner mind of
the Legacy Automatic Climate Control to... your rarely comfortable

Having two credit cards is fine. Paying them off in total every month is
even better. Using them for big payments every now and then is convenient.
But having done just that and transferring the (large) amount you
owe on one to the other account hurts.
The hassle to get your money back out of the overpaid account is...priceless.

Robert Scheck suggested that I get rid of a (justified) compiler warning
in pam_recent by logging only sensible things.
Here's the updated version.

...bank, that is. I just bought this mobile contraption. Should get it around Wednesday. Test-driving it was fine except
for the noncooling aircon which will be fixed before I get the car.

The QLD Transport Authority was (or still is?) running one of those
safety awareness campaigns, with the slogan "Rest or R.I.P.", complete
with huge billboard ads showing a white pillow and said slogan.
(see pg. 5 of this flyer for an idea of how that looks).
Driving up to Ikea and rob's place yesterday, I went past the driver
training centre at Mt. Cotton, which sports such a huge billboard ad.
It also has a neighbour/vis-a-vis, which is announced on the road signs
around the place in the same size as the training centre:
the neighbour is a crematorium. Driver training turn left, Crematorium
turn right. Easy, but don't you forget it!
I wonder which institution was there first, and who decided to show that
particular ad facing the road and the crematorium.
Apropos billboards and coppers:
