I'm no fan of EczemaScript but the recent Westpac/Virgin mess
convinced me that scripting in the browser is not necessarily bad - as long
as I control what runs where and when
(hence I use NoScript and deny all scripts everywhere except where I
know the code).
Yesterday I mucked around with making the
local TV guide website bearable - all I really want to see is the innermost table of
actual information, minus all the square acres of blinking advertisements
and similar drivel.
Upgraded to Firefox 1.5 (actually painless, very different
from past experiences), installed the newest (0.6.4) Greasemonkey,
found a script that claimed to fix that
mess but which was too ugly by far, rewrote it to suit my prefs,
I learned a lot
DOM (and also where Greasemonkey sucks) than I ever
wanted to, but that's fine.
Today I thought about tackling the Virgin problem, but found out that
Joel Hockey has already written a nifty simple small script
that gives you text-based password entry back (without removing the
silly buttons, should you be stupid enough to want them). Thanks, Joel!
But it didn't work. My stubbornness has few limits (and the weather was not
flyable today), so I learned still more about JS and GM and the DOM,
especially about the recent paranoia that badly affect the new
Greasemonkey and wrecks most of the nice things about DOM and
JS (if there were any in the first place).
In the end I fixed Joel's script
(and sent it back upstream) and am now quite pleased with
my army of greased monkeys.
Next step, maybe: adding a squad of platypuses.

Yesterday was my birthday. It rained.
Quite a few people sent their wishes, and I'm happy about that.
My kid didn't and I'm not happy about that.

Looks like the gods in charge of the weather also don't believe in queens,
or rather believe in first soaking and then blow-drying.
Saturday it rained/drizzled/rained/blew, and Sunday it simply howled.
Nevertheless we had a nice weekend - just a camping weekend without flying.

I believe neither in god nor any sodding queen, but whatever it takes to
get a public holiday! (coming Monday)
I and a group of Like-Minded Loonies are going out
to killarney tomorrow afternoon, for a nice cold, maybe flyable
long weekend. Unfortunately the forecast is dreary enough that the invocation above seems
justified...unless god also doesn't believe in queens.

I rebuilt my backup-and-music box recently, because the case
was ugly and because I needed to fit another disk for online backup.
I had a Sun 811 case
lying around, and another similar to a 411. Neither would take the Epia
motherboard, PSU, dvd burner, two 3.5" disks and a 20x4 lcd, but together
they can throw off the yoke of conformist PCism! ahem
So I cut out the plastic top of the 811 and riveted the 411 onto it, which
gives me space for the drives. A face for the open rear end of the 411 was
cut from the cannibalized pieces of my Sony stereo junk and hot-glued in.
The frame for the HDs is an old cut-up drive bay, and the support for the
burner is a piece of sheet metal that I riveted in (hot-glue isn't strong
enough and I didn't want to use expoxy for no reason at all).
The front with the lcd got a painted fascia (balsa) and the IR sensor
was mounted internally this time.
After a shitload of further surgery on the cases and
innards I ended up with this pleasant look.
But you can't see the rear in that photo which is good. None of my small
ATX power supplies would fit without totally rebuilding the thing
(not-so-perfect an idea as I'd basically have to strip all insulation off,
then resolder half the high and low voltage connections and cram all the resulting mess into the franken-case),
so I started looking at DC-DC PSUs. Like this one. Which I did eventually buy,
thinking "the 90W/145W peak PSU I have used so far, so this 200W thing should
do nicely". Cost me about us$100 (with a 9A AC-DC external brick
Little did I know, and for that matter, too little effort did I spend on
research. Plug it in, fire up, works - somewhat: now I get loads of noise
on the audio out connection. Not just mains hum but all kinds of
activity-dependent crap as well. This is when I started doing the research
I should have done before. It turns out that loads of people hate the
PW-200-M for being a crap piece of equipment. First, it's nowhere near 200W,
and some other speciality PSU manufacturers have accused the makers of
shoddy lying advertising. The 5V rail sagged under the load of my two
disks down to less than 3V at times. The 12V line is not regulated, so
iff you're not using a regulated brick you'll fry your gear (especially
the carputer people hate it for that).
The smoothing caps are not exactly large at 390-1000uF.
(But the form factor rocks, which is why I bought it...)
Tried pretty much everything non-destructive, like powering only the
board from the PW-200-M, trying different 12V supplies to verify the noise
is coming from the PW-200-M etc...but no joy. It may be useful for really
low-power scenarios where one doesn't care so much about power quality
(i.e. non-audio application), but for me it's junk...Bugger.
Back to square one: normal PSUs don't fit. Most high-quality DC-DC PSUs
like the Opus
gear won't fit or require 19V like the DC2DC converters....
So for the time being, I plopped my normal small ATX PSU like an outboard
motor behind the box...with some shielding and extra grounding it doesn't
affect radio reception too much. sigh

It does get a bit cold at nights now (+5°C last few days on
the coast, with frost inlands) but the days are still nice at up to 22°C
and, predominantly, sunny. That's the kind of winter I like nowadays.
Some flying pics; last weekend we were rushing from site to site and
mostly parawaiting as in the first pic. This weekend wasn't lots better
but a bit: Saturday was blown out, Sunday was very south but still good
enough for Beechmont. I got an hour of airtime and took some pics of
Marty and Phil.
I've also got two short movie clips (taken with the digital camera, so
they suck) of Rob at Killarney two
weeks ago and one of Phil launching at Beechmont today.

My backup tape stacker died recently, so I had to look for alternate
cheap backup solutions. Goodbye Amanda! snif
Recent tape drives being prohibitively expensive,
I went for two more 200gb disks, one for the living-room machine (aka. tosspot)
and one for an usb enclosure and transfer via sneaker-net to the office.
So far, so good. The choice of available software, however, and my
paranoia re backup storage have an intersection close to \epsilon:
backuppc doesn't encrypt. boxbackup does, but is a bit rough and needs
loads of certificates to get anything done.
On a comparison page about boxbackup I found a link
to duplicity which has a very nice
feature set which meets my ideas of backup pretty nicely:
- Everything happens on the client, the server only needs to give
- Symmetric or asymmetric encryption, encrypt-but-not-sign as well.
- a way to do incrementals that shows deleted files, while still not needing anything but gpg and tar to restore (if you've lost the duplicity program).
- Doesn't need to decrypt anything for doing incrementals,
if you give it a little space on the local machine.
However, it's got a fair number of minor problems as well. Quite some debugging
and head-scratching and four bug reports
later (one two three for duplicity, two with patches and one for rsync with a patch as well)
I'm now set: a dumb rsync server with some disk behind it, encryption (but no
signing) to my gpg key happening on the clients, the result of which ends up
on the server. To do incrementals cleanly, a little unencrypted space
(--archive-dir) is set aside on the clients, where duplicity can store some
hashes and other info of the files it's backing up.
I still don't like python much but I'm at least reaching that
debugging-and-mini-maintenance-hacking level. Syntactic whitespace sucks.

As of 28.5., I'm the 3547th most paranoid geek on the planet.
One of the fringe benefits of the recent trip to Austria was
that Werner Koch gave a keynote speech
at the conference I was attending to, we had a chat and exchanged signatures
(surprise, surprise; opportunities like that...). That has catapulted my
paranoia ranking up a fair bit (from about 23500th place).
The newest analyses: by Henk Penning or Jason Harris
No comprendo? It's all about a type of modern voodoo, oddly-clothed weirdos sitting
around in pubs mumbling numeric incantations to each other and the result of this worship of
mathematical concepts. In short, not something normal people get excited about... but we're
not normal and proud of it!

What a lovely read:
"Emotional balance: The sniper must be able to calmly
and deliberately kill targets that may not pose an immediate threat to him.
It is much easier to kill in self-defense or in the defense of others than
it is to kill without apparent provocation. The sniper must not be susceptible
to emotions such as anxiety or remorse."

An interesting read - if not exactly aligned with any career path ideas I might
