If you have an event that can destroy a nuclear transport flask, you have significant other problems to worry about. It's actually quite fun to watch the videos of randomly selected flasks being torture tested by rocket assisted trains, burning pools of diesel fuel, impact tests on trucks, etc. Transport is probably the safest part of the nuclear fuel chain process.

I personally wrote a steganography tool for JPEG-2000 files for a graduate school project - it just stored data in the least damaging sections of the file. The resultant files were still perfectly legal image files, lossy compressed, and minimally visually damaged.

Kudos for the hands-on. I was fascinated some years ago with progressive GIF overlays and coded some stuff to produce them, not so concerned with stenography and hiding the presence of a message, but more with novel ways of presentation.

One example was embedding a public key into a GIF image. Starting with a standard base image and palette that was the same for everybody, like a shiny golden key floating over a smooth blue gradient... the key bits encoded as a series of overlays that when displayed, made the key sparkle and the background vary in color, all happening over ~10 seconds. The idea was that while most people didn't stand a chance memorizing much "BEGIN PGP PUBLIC KEY BLOCK" gobblegook, we'd be better equipped to remember the distinct "sparkle" of an image. More of a style thing than a useful crypto concept.

I also experimented with things like encoding process/memory access and toyed with the idea of filesystem journals rendered as displayable GIFs. It was a fascinating foray into the realm of data structures and helped me to become the person I am today. I presently jet sewers for a living.

Wouldn't it be strange to see some future Slashdot shocker headline, "Bit Rot Discovered In Cloud, All Data Will Be Reduced to Gaussian Noise By 2030". And like the proverbial boiling frog we deny the problem or postpone dealing with it as everything progressively (but slowly) dissolves into static. People who try to raise consciousness and alarm are booed off Slashdot with comments like, "I can read it. What's wrong with you? posted by folks who are also having trouble reading things but enjoy sniping at others more. Then as it reaches the final stages all electronic mediums are projecting mostly static but people are pretending they see and understand the messages perfectly. And most oddly, when we hit Peak Gaussian something resembling a modern society continues to function. Then unfettered by structure society literally melts into phantasmagorical goo. Something... like... THIS.

Shitty guy, really.

Well, by my measures, he got framed and the whole show is staged by "hidden forces" who pull strings in a plutocracy - tsk tsk, don't do this - hit your fingers with a ruler..

Old fashioned teaching manners, won't change things, just makes them worse.

A story comes to mind:

Walking alone up in the mountains, a herd of elks like 200 or so are spread out on a meadow. I come out of the woods, the whole herd starts running away. If they were going against me - fat chance...

Coin toss is emphatically stupid. I can quite readily toss a coin and achieve a majority one side outcome. Look at two up https://en.wikipedia.org/wiki/... and what is required to in reality achieve a more random event, two coins, one head side up and one tail side up, flipped at the same time from a wooden board and the coins should be pre-1939 pennies (Australian pennies of a particular design). The person tossing regular coins by hand can most definitely cook the results, with two australian king george pennies a wooden board and one face up and one face down, calling heads or tails is far more random. OK simple toss for some game but when you are gambling with your future should not a more careful toss be required or quite simply wait a month, everyone think about it a bit more and have another go. Seriously what the fuck, you could be deciding on world war three occurring (Hillary Clinton) or not (Bernie Sanders), this on a regular coin toss, you people are fucking mad. Elections are meant to be about citizens making sound choices not https://www.youtube.com/watch?... playing Russian fucking roulette, oh apparently you got the bullet this time.

It's a possibility. Of course, I plan to be uploaded into an AI-capable processor core a few years before then, and then delegate the taxi work to a slave node, but hey, a job's a job.

I think, like Achmed the dead terrorist, you have it backwards. YOU will become the slave node :-)

The funny thing is, I wasn't in any way shape or form taking the piss out of them. (If I wanted to that, I would simply have posted this ;) )

Just ask this nice lady:

https://www.youtube.com/watch?...

but on the same not do the engines actually stop spinning? I would have thought the air naturally moving through the off engine would cause it to spin too.

Yes and no. Turbojets and turbofans as well as fixed-pitch props do free-spin in the air. However, they do so at a very low rpm, usually in single-digit percent of their rated speeds. If anything, this is more of a detriment to performance because it actually acts as a big air brake. All turboprops (as well as some of the higher performance piston props) I know are equipped with variable pitch full-feathering propellers, so they actually do come to nearly a complete stop - this helps reduce their drag and increases performance in engine-out conditions. Turbojets and turbofans do have an in-flight minimum restart rpm. This can be achieved either by flying very fast, by cross-bleeding compressed air from the compressor of the working engine, or by using an auxiliary power unit (a small turbine engine designed to start the aircraft without ground assistance and to provide power when the main engines are off or failed) to feed compressed air to the air turbine starter of the failed engine.
Regardless, irrespective if the engine's internal turbo machinery remains spinning at some small fraction of rated RPM, the hot section of the engine cools off pretty quickly, since the heat source is gone and you've got very cold air going through there (not at a very high rate, but still after a few minutes of -50C air flow, it's going to be pretty much chilled). As a further example, here you have a Boeing 747-400 APU (a >1000 shp beast) starting up and going from zero to 100% rated output power in about 30 seconds. The APU is fully automatically controlled, the crew literally just flips a knob in the cockpit and that's it (here it is, near the center of the picture).

Apparently it was the turbine of an old 737-300 with the turbofan removed so one of the mech engineers told me.

Possibly an industrial variant of the CFM56. Don't know what they're called in industrial versions, I'm only familiar with GE's and some of RR's products. Industrial conversions of aviation engines do occasionally happen.

the engine was attached to a large gearbox. Maybe that's where the warm-up requirement came from

Not sure either. Gearboxes don't really need warmup either, they just need lubrication. It's mainly large castings (as occur in piston engines) that are susceptible to heat stress. Turbine engine oil has very low viscosity (far lower than automotive engine oil), so I don't think viscosity of the oil is much of a factor either... I dunno, maybe the manufacturer just wanted you to really baby the engine.

According to the first link:

Use of the 85th percentile speed concept is based on the theory that: the large majority of drivers: are reasonable and prudent

Unfortunately, 80% of participants in one study rated themselves as above-average drivers. This disproves the above theory that "the large majority of drivers are reasonable and prudent."

So the rationale behind the 85th percentile rule doesn't hold up to scrutiny.

If you have any further doubts that traffic engineers are raving lunatics, please watch this short video created by a recovering engineer. It's absolute madness.

Maybe it is time to introduce people to Flyting, which Wikipedia describes as " a contest consisting of the exchange of insults, often conducted in verse, between two parties".

Nowadays, we have a different name for that type of thing.

> Since when have we reached the point where you aren't allowed to annoy or offend people?

When PC became Political Censorship. :-/

America has, sadly, become a land of wussies / pussies. :-(

"Oh noes! I can't speak my mind because I might 'offend' someone."

If someone is offended by words, ideas, or so insecure that they feel the need to censor others then there is only one question to ask them:

When are you going to grow up??

This tacit censorship by trying to dictate others to remain silent from speaking their opinion (regardless of how popular or "correct" it may be) is shenanigans of pandering to insecure people that have no respect for others that someone _might_ actually disagree with their myopic POV.

(i) No, I'm not watching some half hour video of someone talking. I can read faster than he can talk. Give me a transcript if you want your ideas spread.

(ii) What's a "feminist/Islamist"? That's like saying "atheist/Evangelical".

(iii) It's "their".

Everything about that was a farce. From the "Poop swastika" to the claim of getting "run over". It was all lies.

I'd say in this case, Cleese has a point. Today's brain-washed college students are merely proles awaiting their assignment in the machine to perpetuate the machine. The only thing they're against is people they perceive as having "unfairly" succeeded. (I can agree with that opinion partially, which is ironic, as according to one measure I recently saw it is likely a large majority of accounts here of folks over 30 are likely in the 1%)

I also recently saw a comic who was "funny" I'd guess about 50 years ago. His delivery and topics just weren't funny to me. Were they offensive? Quite likely to more than one person, but that's not the point. Do I complain about him? Of course not, I just mark him down in the list of "not funny" and move on. Railing against a comedian because you find them offensive is idiotic, just don't go. Apparently college kids need to be handled with white gloves, and apparently more than a few also require those stylish long sleeved white jackets.

If you want someone offensive, bring on someone like Carlos Mencia. Just be prepared to laugh in spite of being offended. What's hilarious is I walked into a fast food place the other day and was asked "grilled or creepy"? I chuckled for at least the next hour. That reminds me of boogers (1 cheese-boo-ger) Damn, now I am not going to get any work done.

His insensitivity to people who "walk funny" is just intolerant and cannot be abided by.

Shame on you Sir!! I hope I find you soon!!

I was doing similar calculations for an A-380 but I doubted my results as they pointed to rate of energy recovery being in the order of a small power station for 10 seconds.

Which probably means that your calculations were correct, it has to dissipate energy at a rate of at least
dozens of megawatts.

Max landing weight of an A380-800 is 391000 kg, landing speed around 140 knots (72 m/s) - note that
this is airspeed, so ground-relative velocity can be slightly lower. Still, the hardware has to be designed to
handle the maximum case.

This results in a kinetic energy (1/2 * m * v^2) of nearly exactly 1 GJ.

So to stop in 10 seconds, energy dissipation has to happen at a rate of 100 MW. Douple the stopping time,
and it's still an impressive 50 MW.

A single brake on an A380 wheel can handle a 5MW braking (once, in an emergency).
An A380 has brakes on 16 of its 22 wheels. Add the other deceleration systems (spoilers, reverse thrust),
and a complete A380 can probably dissipate kinetic energy at a rate of a considerable fraction of a
gigawatt in case of a last second rejected takeoff (faster and quite a bit heavier than the worst-case landing).

That isn't a small power station anymore.

Given that Clinton did win all six flips, the odds that the flips were fair is ... hmm?

The summary is disingenuous and misleading, though if you parse it closely enough it's not necessarily an outright lie. Clinton did win at least 6 flips, but she also lost at least a handful of the dozen or so total flips.

https://www.youtube.com/watch?... has video of one of the several that Bernie won.

6 of 6 looks fishy only because it's cherry-picking Hillary's wins and ignoring Sanders'; there were about a dozen tie breakers, and Sanders won several of them.

Here's one, from Hardin Township: https://www.youtube.com/watch?...

They have released this demo : https://www.youtube.com/watch?v=kw0-JRa9n94 which looks pretty decent. You can find some artifacts (mainly the occlusion of the little robot which could be better). The depth of field looks pretty cool in the second part and the resolution seems decent (at least for the 1080p camera and for the few frame it is actually in focus, might not be perfect for the eye though).
I have no idea on the volume/weight of the device though.

And recruiters will demand five years of Swift 3 on their mandatory qualifications lists, as they do with Swift 2 right now.

And for extra weirdness, Sanders wins.

98.4375%.

And, in fact, there now seem to have been at least seven coin flips, and Sanders won one of them. So now we're at a mere 94.53125%.

https://www.youtube.com/watch?...

The summary says both "at least six" and "all six" suggesting the story was put out before all the facts were known simply because it's a good story. Maybe Hillary's team have just been quicker to publicise their coin-toss wins.

I wonder where this video of Sanders winning a coin toss came from then.

For not having watched television for 3 decades, you seem to be able to practically quote The Simpsons:

We can't bust heads like we used to, but we have our ways. One trick is to tell 'em stories that don't go anywhere - like the time I caught the ferry over to Shelbyville. I needed a new heel for my shoe, so, I decided to go to Morganville, which is what they called Shelbyville in those days. So I tied an onion to my belt, which was the style at the time. Now, to take the ferry cost a nickel, and in those days, nickels had pictures of bumblebees on 'em. Give me five bees for a quarter, you'd say.

Now where were we? Oh yeah: the important thing was I had an onion on my belt, which was the style at the time. They didn't have white onions because of the war. The only thing you could get was those big yellow ones...

It's worse than it sounds. I watched the first episode and laughed. It has worse technobabble than regular CSI's "GUI interface using visual basic to track the killers IP"... By far.

Ah, well that is indeed a bird of a different feather then. Even with a non-releasable Eagle, releasing that poor bird into an enclosed space filled with people is just not acceptable. That trainer will be smoking a turd in 'murica hell for that one.

OTOH, here's another Bald Eagle showing it still has the proper American spirit. A true American, that bird.

Ownership comes and goes with their ideas of monetization and world domination, but it's good to see you're still a Soul Man around these parts.

Sorry, but no, you're wrong. Here's another video of the event showing the handlers and the pastor announcing the eagle's arrival and that it was being released from the balcony. "Eagle flying in the Chapel window" should read "into the Chapel window".

Basically, it's tough to trademark a word that describes the thing you're selling. "React" describes the videos they create. Although this doesn't conflict with any valid trademarks the USPTO has registered, it shouldn't survive a challenge in court.

In the United States they were endangered most of my life (until about 10 years ago), and still to this day it is illegal to "own" one in captivity except under certain very rare circumstances.

Evidently, it is not rare enough circumstances to prevent this particularly egregious fucktardery, which also shows that some of the most "patriotic" 'Murkans have no problem with it at all.
