Saving the paint pot [Dec. 17th, 2009|02:25 am]
[Tags|]

It's a good thing he was never deported. He's been a fantastic instrument scientist. And he made ace snow domes containing a tiny little version of the Sydney opera house with tiny little red "No War" lettering.

But I am glad he wasn't involved in the latest Opera House shenanigans. We still need him.

What he said.

I saw Mary and Max over the weekend. Amusing film. Bizarre ending though. I guess films based on true stories don't always have to have happy endings.

More red sunsets! [Dec. 7th, 2009|11:58 pm]
[Tags|, ]

Why, I don't believe I've posted this yet.

I have fun with the interval timer on my camera:



Original higher res version is here (which, if you have the bandwidth, is highly recommended by my humble self), but I'm not usually so prompt in updating those versions as the ones on my youtube "channel". Youtube unfortunately considerably darkens all of my videos I put on it, which is not a great result when you're filming in low light conditions.

Actually, I just put up yet another one, this time from the dome as it rotates through a series of pointings, ending up back in the direction of dusk.

Have I mentioned we have awesome sunsets up here?

Paul Kelly [Dec. 7th, 2009|09:23 pm]
[Tags|]

It's Summer, it's hot, it's perhaps appropriate to watch cricket and drink beer (if they are your tastes, and beer certainly is mine), and I feel that that's the perfect time to listen to more Paul Kelly (just as Winter, Spring and Autumn are also perfect times to listen to more Paul Kelly). What an asset to the country; him and his collaborators.



(here for PLOA viewers)

I didn't get to listen to all of tonight's Paul Kelly tribute part B because Red Dwarf was on the same time and I was relying on JJJ's stream not to break on me 3 minutes into the recording due to server overloading, but do recall that it replays on Sunday at 5-6pm AEST.

Dear filesystem developers (and Stewart Smith) [Nov. 29th, 2009|10:18 pm]
[Tags|, ]

Dear filesystem developers (and Stewart Smith),

It's an old discussion, I know, but please read all the comments on Ts'os blog post, at least as far as Daniel Colascione's comment (and tell me if there's anything worth reading beyond his post, because there's kind of a few of them there).

rename() already implies barrier. No, not universally, but close enough as dammit on any systems that matter (remember, POSIX is a minimum requirements, lowest common denominator thing. You are allowed to not suck as well[1]). If you want a rename that doesn't imply barrier semantics, then please invent another rename2() call, but please don't break 30whatever years of application programming by breaking standard semantics of rename().


Now while were at it, could we write a filesytem where the atimes are all stored on a contiguous part of the disk rather than in the inodes so I get to keep my atimes (don't care how often their synced, as long as best efforts are made to write them to disk eventually and completely) and you get to keep your filesystem performance?


Yours sincerely from an ignorant user who likes ponies,

[1] Yes, POSIX doesn't say much about what happens over system failures other than to expect FAIL. XFS loses data and remains POSIXly compliant. But since the primary purpose of a filesystem is to not lose data, I'd rather it try to not lose data. To do anything else sucks, and this would be the primary reason why I think XFS sucks (and note that I didn't say that I think every application out in the wild sucks, as bad as many of them are. I think the application expectation is sane. It's just not all filesystems that are sane).

Two sunsets, a tree and a rock [Nov. 28th, 2009|09:09 pm]
[Tags|, ]

It's been a little dusty lately, but these are some I prepared earlier (a couple of years ago).

dscf2290 dscf2291

The past few months haven't seen the red disappear from the sunsets:

r0013541


Most of the photos I took last week were crap partly because of the dust in the air (and partly because I have a new camera, but primarily because I'm a crap photographer), but I don't mind these ones:

pb230942

pb230945

That last photo was taken about when I should have been heading back to the observatory to start my shift, but instead I kept on heading up. I must be one of those fools who gets lost in the mountains and needs to be lifted out by chopper. Instead, an hour before I was due back, 3 hours after I left, I got lost when it came time to work out which particular goat track to go back down, found the right goat track, ran part of the way back down the mountain, nearly broke my leg and sprained my ankle half a dozen times, avoided any contact with snakes, and got myself back to dinner at the lodge only 10 minutes late. It was only upon trying to get back out of the dinner chair that I realised I was now officially buggered.

TAC shock and awe motorcycling campaign [Nov. 26th, 2009|09:35 pm]
[Tags|]

Tomorrow's headline:

"Due to new bikie laws, no more than three bloggers on line at the same time".

I just hope they don't allow those nasty hardcore Ulysses Club patchclub members to blog.

Compare and contrast TAC's campaign vs South Australia's and other campaigns (or how amateurs would do it)

TAC and other insurers actually want to reduce damages when a motorcyclist is injured when they weren't wearing full protective gear. Never mind if they end up with a wrist injury and they weren't wearing leather pants. Never mind if the sole reason they crashed because some dickhead in a white van decided to pull out without looking. They wasn't ticking the right boxes! Them nasty rule-breaking bikers!

The great left wing scientific conspiracy has been revealed [Nov. 26th, 2009|12:46 am]
[Tags|, ]

Dammit, George Monbiot is onto our scheme.

It was a very elaborate scheme to falsify physics since the very early days when James Clerk Maxwell was still working out the field equations. I admit that I was a part of this scheme — for this I am deeply sorry.

I do hope that they continue to pay me though.

Odd conclusion to make [Nov. 21st, 2009|01:36 am]
[Tags|, , ]

From SMH:

The director of the NSW Government's Centre for Road Safety, Soames Job, said a major cause of the sharp increase in the road toll - up from 321 deaths in 2008 to 415 deaths in 2009, as of Wednesday - was the increase in ''two-wheel vehicles''.

He said that as of midnight on Thursday, motorcycle fatalities stood at 65 for 2009, compared with 44 fatalities for the same time last year, while the number of deaths of bicycle riders had more than doubled in the same period, from six to 14.

They're not saying the number of bicycle riders is increasing (they aren't on the time scale of a year; motorcycle sales are up quite a bit though), and yet bicycle riders are dying more. Could both of these results — that motorcyclists and cyclists are being killed more — be explained by car drivers getting less careful? The cars go too far in insulating the drivers from the road environment, and cars full of modern inventions like traction control, anti lock braking, and enormous truck-blocking-pillars full of air bags, insulates them from having to have enough skill to drive. These inventions do nothing for the poor guy being hit by someone who's risk compensating because they think their new volvo that stops automatically when they're not paying attention, is safer.


I wonder if I should be worrying that we might soon lose the right to ride on the road at all?

Here's a letter to the editor of the SMH that I had cooked earlier (I should probably abuse drivers less if I wanted to get published):


Carl Scully reckons that cyclists don't deserve to ride on the road
because we don't "pay fuel levies, tolls, registration and licence fees,
as well as the huge cost of buying and running a motor vehicle".

I personally don't see why the cost of the motor vehicle has any relevance
here (people are free to buy a more appropriate choice of vehicle if they
wanted to), but I'll let Carl have that argument. But now that I know his
feelings, I'm sure he wouldn't mind if I opted out of paying my portion of
the taxes and the 2.5% medicare levy and surcharge that correspond to the
15 billion dollar NSW health budget. I don't want to pay for the stressed
out and overweight lazy slobs stuck in their tanks on the freeway each
morning. Perhaps if Carl had provided bike paths maintained up to a
suitable standard we'd expect of a transportation network, the fat lazy
slob would be getting fit riding a bike instead. As a bonus, while on the
bike, they'd have less chance of contributing to the carnage on the roads,
saving even more health dollars.

Gah. Bring on winter. [Nov. 20th, 2009|12:00 am]
[Tags|, ]

I've just worked out why the village idiot (s) have their heads in the sand.

It's because, if you dig a few tens of centimetres down, it's cooler down there.

You need to be able to get as cool as you can get this fine November, and if it takes sticking your head in the sand to be able to get cool enough, then so be it, I guess.

Are we currently in another dust storm? The weather was *really* weird today (We had 10mm of rain fall in 20 minutes in town today, but they must have fallen in 10 drops contributing 1mm each. If one drop was unlucky enough to hit you, you ended up saturated from head to toe, they were so big. There was no rain up here on the mountain though), the humidity is plunging (30% now, up here), yet it feels damn muggy. The air outside just seems so *thick*. And yet we have the telescope open and are getting *some* photons down the fibres. I can barely see stars outside, but we're still getting half the photons we were expecting.

Software maintenance [Nov. 17th, 2009|09:34 pm]
[Tags|, , ]

This article on software maintenance unwittingly describes a lot of modern software in the quote


In software, adding a six-lane automobile expressway to a railroad bridge is considered maintenance


and makes a comment on modern society and traffic planning while we're at it.


Let's "upgrade" a nominally efficient system that may be running suboptimally and add useless but popular measures that will buy votes but inevitably moves people less efficiently! Just like the endless new feature upgrades in firefox vs 8 year old usability bugs! Just like the endless freeway upgrades and tunnel construction vs the Melbourne city loop that is not yet working as designed 50 years later!

The carbon subsidisation scheme [Nov. 15th, 2009|04:39 pm]
[Tags|, ]

I just made yet another donation to GetUp after reading yet another dissapointing article in the paper. Looks like the village idiot might have won this battle, but at least I should inform them that "indefinitely" means "to an indefinite extent; for an indefinite time", and hopefully Peter Garrett's short and jocular comments were right on the ball.

Barnaby Joyce [Nov. 8th, 2009|11:00 am]

I think we're witnessing the birth of the next Wilson Tuckey.

It's funny. When he was less senior, I guess people weren't reporting his strange opinions so much, so I had only heard some of the more sensible things he had said. Or maybe I was just applying the CIA principle — the enemy of your enemies is your friend — as at some point in time he was trying to stop some mining in his backyard.

But these days, he's the perfect caricature of the old (Nationals voting) farmer at the coffee shop yesterday who doesn't believe in the moon landings nor cancer, doesn't like paying taxes, then complains about the state of the roads. Oh, and he's been wondering why it hasn't rained properly here in 20 years too.

Go Barnaby!

Comparison of computers with bicycles.

Thank goodness there's never any chance of mistaking Tiagra for Ultegra though.

In unrelated news, I seem to have gotten over the various winter illnesses, and went for my first not-a-race of the season lastnight, but seem to be suffering from the old lack-of-bloodflow-to-the-brain 40 seconds after sprint finishes and 20% gradients.

I like how the mayor takes the piss about our broken town clock at the end of this video clip:

AAO celebrates 35 years.

(video links are embedded in this if that page demands plugins you don't have).

Film of Prince Chucky and the far more eminent Fred Watson here.

I love the quality of local news.

(thanks to the addition of a sun dial, I can now tell when I'm running late for the bus in the morning. Except it would take me about 20 seconds to read the dial, and I'm usually running about 20 seconds late. You'd think I'd get up a minute earlier).

I wish women made the first move more often.

Creepy

Or, maybe they do more often, and that it doesn't happen to me perhaps suggests the reaction in the thought bubble is the reaction I should be expecting?

Gah, living in my brain can be so damned annoying.

I just found the wackiest bug [Sep. 28th, 2009|03:49 pm]
[Tags|]

I use XEmacs in combination with nvidia drivers running a dual-head Twinview setup. And occasionally, xemacs loses its ability to have its cut buffer pasted into xterms. And only cut and paste involving xemacs transferring to xterms. And I just found out, only when an xterm is on the other monitor. I can drag that xterm to the same monitor, and it works. I can drag it back to the other monitor, and it pastes some really old stale data that was once indeed in the cut buffer.

Wack.

(I've had an entry in my TODO list for the past year, trying to get me to migrate my xemacs configuration files over to emacs, because emacs seems to be much better maintained these days (and doesn't suffer from this particular bug, whomever this bug belongs to). But I haven't done that yet.)
