12. Its roof is made of 2,194 pre-cast concrete sections.

13. These sections weigh up to 15 tons each…

14. …and are held together by 350km of tensioned steel cable...

15. ...which if laid end-to-end would reach Canberra

16. The roof is covered with more than one million tiles, made by Swedish company Höganas.



well i was wrong according to a site which says the weight of the entire building is 161,000 tonnes. i was out by a factor of 2!


i did not take into account that the bloody ribbing was hollowed out concrete. i also included the forecourt pavement and foundations in my short calculation.
what a waste of time!
i should have thought "no! just go where you're going and look it up on google when you get home!"
but i like the challenge of a puzzle.
whatever

b9 and I were discussing my gender the other night. He didn't think I sounded like a female. I told him he was right and explained the unfortunate incident when you and I swapped genders.

I'm not an it. I'm an AustrAlien and I think you are too.

Which reminds me, atnight, can you see the stars really brightly where you are? I can barely see the Milky Way due to all the city lights.

Yes, the stars are bright here.
When I used to go for a moonlight bike ride I would get so distracted by the stars I kept running off the road.
They're beautiful.

stop it. You're making me feel old. I remember when Abacus model 1 came out. It was around 1700bc if memory serves me correctly, the first models came out with GWBASIC pre-installed.

just something i better write down or i will forget it all and never think about it again................

i saw a show last night called "mega moves" where they were trying to dismantle a big old jet, and they had to get the wings off it, and there were (apart from the main bolts) 400 small screws to unscrew.
anyway the old plane was about 60 years old, and the small screws proved very hard to remove.
they had just the single slot for a standard screwdriver (not philips head).

so it was a professional team and they got a pneumatic screwdriver drill thing to unwind the screws, but they found that they did not have the muscular power to press the screwdriver head against the screw hard enough for it to grip.
the screwdriver head just skipped over the slots and started to grind them down, so they had to stop trying to take the screws out.

they instead did a lot of damage by just drilling them out with a bigger bit than the screw or the hole it was in.
they just ground the metal away.


well i wondered how one could design a screwdriver contraption that pulled the screwdriver head into the slot with a force that was much greater than human muscular capacity to force it down.

electromagnetism?
no. the surface around the screws was aluminium which is non ferrous and not magnetic.

suction cup vacuum plug?

no, there are may creases in things that would prevent a sufficient vacuum being obtainable inside the cup.

like screws in old wooden planks, and porous materials.

what to do hey? think of a combination of the answers to both of those conundrums and design how to go about it.

with porosity, the answer would be to fill in the gaps
with non ferrous materials, the answer ........ hmmmmm.

with plane wings, the suction cup idea would work well, but to design a new screwdriver that forces a downward pressure on a screw (as well as a twisting pressure) that is not achievable by a human would make lot's and lots of money.

maybe the answer is to consider the screw expendable, (so long as one does not damage the hole it is removed from) and design a screw driver that drills a tiny hole into the centre of the screw and....and then what???

and then clasps onto the screw from a little tunnel inside the screw thus providing much more surface area for friction in order for the screwdriver to twist the screw out of the hole.

oh who gives a f**k anyway?

The cheap Chinese Spyderco Civilian finally came in da mail [from China]; I'd rather outlay $15 than $300 to see if I like it or not (I'm getting close to acquiring 300 buckaroos over the past 2 months).

It's not all that bad; fit and finish seem perfectly adequate. It's all about as I expect. They copied the VG-10 steel label, but I'm pretty sure it's not going to be that. It's probably some Chinese variant of 440C, which isn't bad, but it's not VG-10 IMO.

I'm not sold on it being a good self-defense weapon simply because you can't stab with it; it could do some nasty slices, but they won't be incapacitating. It'd work against the uninitiated that jump you in the street for a robbery, but I don't see a rapist or murderer being deterred by being opened up. Neck would be the only guarantee for a quick death if you swung it for a good slice, which would be very hard to pull off on a moving and fighting target.

I'd rather a folder that can stab and slice.

I don't think I'll go for the real deal. Perhaps the smaller Matriarch which is about 1/3 the price of the Civilian, but is pretty much the same; just a little shorter.

An Endura (which can stab and slice) would be a better weapon IMO, and it's a lot cheaper.

An Endura + the Matriarch would be a better outlay than a single Civilian.

This be it. Looks more nasty than what it is. It'd be pretty good on a boat or something where you have to cut a lot of rope (especially being a cheap Chinese copy, so you wouldn't worry about banging it around much).

You see, if a kid is outside, and you can hear him playing, you're also going to be able to hear a car idling ~80 meters away, the same with a door closing on the car, not to mention actual acceleration (no matter how slowly).

That's why the "official" story makes little sense to me unless a person snatched and grabbed and then ran for quite some distance before hopping into a car (which could be why the dogs couldn't track a scent; he was being carried). This is with the two suspect cars which weren't far away being a part of the official story.

That's the only type of snatch and grab that makes sense IF the family weren't lying about hearing the kid playing outside (hear the kid = hear a car).

If this is the case, then it would have been most likely targeted and not random (random is always a chance, but you organize these things based on likelihood; if random and smart, the chance of it being solved is pretty much 0 without someone talking).

Yayy! I love old computers! (Please tell me it's not weird for a modern day 14 year old to like them)

Crap! I'm so sick of school! I still have 3 months left. It's been going for a little over 3 weeks and I'm not exaggerating when I say I literally am on the couch every waking second except on weekends when I go to work. My butt is freaking numb. Then one of my professors that I sent an email to thought that my email had a "tone". What the heck does that mean?! She thought I was upset and I WAS UPSET because two other students didn't do their homework like they were supposed to and the class was depending on them so we could do our part. My whole schedule was thrown off. You're damn right I have a tone! When my grade depends on someone else and they leave me hanging not knowing what I have to do to correct the situation, I'm going to have a "tone"! I don't think those patho professors understand that they are giving way too much homework. I have to study for a test now that is due to be taken by the end of the day and I haven't even started - I'm too busy doing papers and reports! Screw this crap. Pretty soon I'll have to start adding to my calendar times to go to the f'n bathroom!

ImAnAspie,

I had a question for you actually, what filesystem is best on Linux or Unix when dealing with large files?

I am creating a backup and everything is going to be a compressed file, every file will at least be a GB. Its an encrypted 3 TB hard drive with dm-crypt. Is ext4 ok or should I go with another one?
