I don't think it works like that. He wouldn't be able to _open_ another drawer if any others are open. This is to stop the thing toppling over. Nothing stops you closing the doors, as our friend did with the bottom one.

Long ago.

I used to rent out a house I owned in the nearby city to students. Nice little earner while it lasted. Anyway, I also kept a server in the (fortified) attic because the cable internet in town was much faster than in our rural office. There was a firewall running as well, to keep the students at bay. It would go down every now and then which would have meant a 90 minute round trip to fix, except I had one of these (or rather the current model at the time) :-

https://dlidirect.com/products/web-power-switch-7

The server and firewall were both set in their BIOS to turn on when the power returns, and the remote power switch must've saved me a 100 hours of sitting in traffic. The switch itself never crashed, even when it got filled up with dust from some building work. I remember that its uptime looped back to zero at about every 30000 hours. I've still got it somewhere...

Amazon meets the incredible SHRINKING UK taxman

How it works:-

https://www.bbc.co.uk/news/business-40884753

"Each full-time employee gets given at least £1,000 worth of shares every year. They can't cash them in immediately - they have to hold them for a period of between one and three years."

"HMRC rules allow employees to receive £3,600 worth of shares from their employer tax free every year. Most of these awards are below that threshold. The employee wins through a tax-free windfall, Amazon wins because it hasn't got to pay any cash out, which leaves HMRC as the big loser."

"the practice of giving staff shares is widespread, generally seen as a good way to promote loyalty and engagement - and is 100% legal."

Re: hahahaha... parse this, AI fool!

The The. Yep!

"It was when Johnson and Christopherson flew to South America to film the videos for "Infected" and "Mercy Beat" that events started to spiral out of control. Filming in the Peruvian jungle in Iquitos, Johnson used the services of a local Indian tribe as guides. The Indians introduced Johnson, already an enthusiastic user of drugs, to the hallucinogenic concoctions used in their tribal rituals. The video for "Mercy Beat" captures a scene where during filming the crew were attacked by a rally of Communist rebel fighters, angry at the appearance of what they considered Western intruders. Johnson confirmed that the scene was genuine and unscripted, and admitted that at the time he was "so high", recalling the madness that had ensued: "Someone produced a snake which I was grappling with, and I hate snakes. A monkey bit me, and then me and this guy, who I'd only just met, cut each other and we became blood brothers, rubbing blood over each other's face, stuff like that." "

Re: Man on the sun

"Contrary to popular belief and what most mathematicians will tell you, all of the digits in the decimal expansion of π are known! They are: 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. It is the order that they appear that is not known."

Reminded me of π = 16·arctan(1/5) − 4·arctan(1/239)

As proved In 1706 by John Machin, Professor of Astronomy in London. He used it to compute π to 100 digits.

You can use the Maclaurin series for arctan. The smaller the value of x, the faster the series converges.

arctan(x) = x − x³ /3 + x⁵/5 − x⁷/7 + x⁹/9 − x¹¹/11 + . . .

Re: Timing is everything

A long time ago, in a galaxy far, far away, we had a few of those days out, mainly to keep the "Investor in people" sign up in reception. When we went on one 'teamwork' edition, I made sure that I was in the same group as my fellow engineer, let's call him 'Dave'. Anyway, we were set a series of tasks. Dave and I agreed to take turns distracting the group of H.R. people, accountants, sales guys and telephone sanitisers, while the other one of us solved the problem. E.g. while Dave chatted to the group, I rescued a teddy bear from inside a (supposedly electrified) 10 metre diameter circle by making a dog catcher out of a scaffold bar and some rope. Whole task took about two minutes, breaking the previous record by about 40 minutes.

Anyway, the whole day's missions were finished up in less than an hour. We didn't learn very much about working as a team on the course, but the rest of the day in the country house hotel bar made up for it. The H.R. lot never invited engineers to their away days after that.

We didn't get laid off though. That came c.10 years later when an American firm bought us out. I got a H1 visa and went to California to put one of them out of a job as revenge.

"Synthetic nitrate production only achieved scale after the war's end."

Well, it started during the Great War. The British sank the German fleet in the South Atlantic in 1914, denying them access to Chile, so the Kaiser had to make his nitrates with the Haber process.

The normal decay chain of plutonium 239 goes through uranium 235 via alpha decay. But, OK, you're right, in a bomb there are so many neutrons crashing into things, that there's a zoo! I should've said that some plutonium turns into U-235.

Re: Banana Equivalent Dose (BED)

@Tomato42, yes, I get that it's there to try to explain to radiation exposure to people, but I would hope the commenters here understand what a sievert is. The fact of the matter is that eating a banana makes fuck all difference to your radiation exposure, because you piss out the potassium anyway. Now, your C-137 has a biological half life of c.110 days in a human*, so exposure to C-137 is more dangerous than potassium exposure, because it's an additional dosage.

Caesium is also more dangerous than potassium if you do this with it.

Re: 1952?

Indeed, but Caesium-137 is produced from the nuclear fission of plutonium as well as uranium. That's because the plutonium 239 turns into uranium 235. So, the first substantial release of Caesium 137 was the trinity test.

"Microsoft has included support for negative leap seconds just in case."

From c.2000 to c.2015 the Earth wasn't slowing down much at all. So, this is probably a sensible inclusion.

https://upload.wikimedia.org/wikipedia/commons/5/5b/Deviation_of_day_length_from_SI_day.svg

One reason for this is post glacial rebound. During the last ice age, the huge polar ice caps gradually squished the mantle down at the poles and out at the equator. This increased the planet's moment of inertia, slowing the spin and lengthening the days. Conservation of angular momentum and all that. Then the ice melted relatively rapidly, which again increases the moment of inertia, as water has moved from the poles to the equatorial regions, again slowing the spin of the Earth. However, now, as the ice has retreated, the mantle is slowly rebounding at the poles, reducing the bulging waistline, which contributes to shortening the days.

Read all about it:-
