Whilst we're off read bomb stories, check out The Eyewitness account of P. Siemes, a german priest who was on the outskirts of hiroshima when the bomb was dropped.
Perhaps if all these accounts were put together and taught to 15 year olds, there'd be a lot less warmongering in the world in another 20 years.
C'mon slashdot, where's the love? A simple 'You are mis-informed' would have sufficed.
Colour CRT's have three filaments in the guns to provide electrons to 'fire' at the screen. They operate at about 'an orangy glow' which is likely in the order of 2000 degrees C. With the advent of remotes and multiple power cycles a day, the filaments are left powered at 4-500 degrees C (just below 'visibly glowing'). This provides quicker startup, but more importantly provides longer filament life - the filaments, being still relatively warm, do not suffer the same thermal stresses as from a cold start.
As a side note, this is why some labs never shut down their high-temp furnaces, the silicon carbide elements transition to a crystalline phase when the temperature drops to a few hundred degrees, often cracking a good element that would have lasted a few more thousand hours at operating temps (1000 deg C).
Where the hell is my hypersonic flight to tokyo? Oh, another 10 or 15 years yet? Well, I guess I'll just have to suffer on with my flying car... er, personal robotic assistant... er, fusion-generator in my basement... eh, forget it. I'll be in the lounge room watching Astro-Boy reruns.
Even governments back their cash in gold. Not anymore. It's all theoretical now, baby. Or did you really think that there's enough gold in Fort Knox to redeem the entire US paper currency float?
We'll just have to hold off another 6 months until we can get the cheep korean "Sorny" knock-off with a macrovision copy protect function that doesn't work due to, er, "Poor QA". Yeah, that's it, "Poor QA".
From what I can tell, it was use The Bomb, or invade Japan. Estimated losses of allied forces invading Japan were gigantic. It was hardly mindless, it was simply a case of Us vs. Them. In that particular point in history, it was them. You don't have 4 years of war and then say, "Hell, we don't need to prove to them that we're capable of leveling their cities, lets just keep killing our troops for a few more years - we'll win eventually." You drop the damn Bomb, twice, to show the other side that you can make them, and they should really consider surrender.
And the fact is that once The Bomb was about, there were lot of times where major powers would have usually gone to war, but were held back by The Bomb.
So, for the sacrifice of 110,000 people, countless others got the chance to live.
The article you linked to is correct, of course - For maximum efficiency, size your A/C to your (expected) load.
Standard australian car TX valves are sized at 2-2.5 tons.... perhaps your climate can get by with smaller A/C units. They're mainly sized that way for great pulldown when you climb into your car of an afternoon and everything inside is at 65 degrees C.
I'm an auto electrician working in an underground mine. When you're 900m underground and its 35 degrees - and foggy(!!), with a 600HP V8 diesel sitting 20cm beside you outside the cab, things are a little different:-)
You pretty much can't get an airconditioner big enough. We use (R134A) 4kW evaporators and 6kW-sized condensors, and head pressures in system are still a little on the uncomfortable (300PSI) side. These units use the biggest-rated commonly available automotive components, and they manage to just cool a cab that wouldn't fit two people in it.
Personally, if the article submitter is in a dry climate, go buy an evaporative unit and leave a few windows open to let the humid air out.
This is all very well and good, but he's missing one thing - capacity.
Air-conditioning systems are sometimes rated in "tons". That's "how many tons of ice required to melt in a 24hr period to get the same cooling effect."
Surprisingly, in AC terms, a ton is not a very large unit. A typical car air-conditioner is about 2-2.5 tons. This size AC is capable of cooling about half a house. So, a 5kg bag of ice? Forget it. Go buy a real air-conditioner. Scrounge around - 30 bucks can buy a decent old second-hand unit.
Thousands of tons of crap enters the atmosphere every day. You could probably make a suit out of,say, plutonium and still have negligible effect considering:
One spacesuit+electronics - 50kg, tops. Atmosphere - 5,000,000,000,000,000,000kg (by most estimates).
Even guesstimating that it might incinerate and cover an area 1/8th the size of the globe during re-entry, that's still pretty much SFA. Even with plutonium being the nasty thing that it is.
Of course, the associated problems of dealing with 50kg of plutonium in one place at the same time is left as an exercise for the reader.
But that story was submitted after being awake for 20-something hours, so I hereby blame my sleep-deprived state for any spelling and grammatical errors found. If you think the story itself is nonsensical, well, I blame Society.:-)
In the modern world, Cargo/Container/Bulk carrier ships can't be sail-powered. They're too big. they run on tight schedules with big penalties. Modern business demands that they can ship 500 cars at once from Korea to the US in 8 days, guaranteed, in any weather. And by god, they'll pay for it, because in the end it's all tacked onto the price *you* pay.
With mythtv (and mythdvd/mythvideo), one cannot easily rip -> compress a DVD and keep it as , well, a DVD.
However, one *can* rip the various video segements of a DVD without any hassle with mythdvd and store them. Eg, the "making of" sections of DVD's.
You can also select which audio track to rip, although I believe you cannot rip multi-track (that is, standard audio and a commentary track) with the mythdvd ripper. You can rip different versions of a movie with (for example) the directors commentary as audio , but that's getting a little wastful of disk space.
Me? I just rip the "bare" movie - at 750kbps PAL video, with a two-pass run, they come out fine. The best part is that with the MythDVD ripper, it can be done with about 3 presses of the remote.
But Dave did it nontheless. And he was pretty pissed off about it too.
In fact, if you listen closely as Dave is removing HAL's memory cores you can hear him mutter, "So, make me have to bust into my own ship, through an open airlock, without my helmet? Take that, you fucker!"
Well, he does on *my* version of 2001. The one in my mind.
Some of the most successful early computers were analog computers, capable of performing advanced calculus problems rather quickly. Before digital computers became the mainstay of computing, analog computers were quite common. Analog computers use varying voltages and currents to represent variables, and various types of amplifiers to represent factors in differential equations, with the result being a final voltage or current that can be read out on a meter or graph. Analog computers were heavily used in process control situations, such as calculating the correct aiming of the big guns on board a battleship. Many variables had to be considered simultaneously, including the position of the ship, the position of the target, the type of ammunition, the wind and other weather conditions, the constant motion of the ship from the action of the sea, and myriad other variables. The analog computer would simultaneously combine all of these variables to generate a real-time result that would control the large servomechanisms that aimed the guns to assure that their ordinance would be delivered accurately to the target.
They were,however, a real bitch to sort out. So the computer world focused upon digital designs, which , it turned out, were a lot easier to do.
in 5-10 years a lot of those $2,000 cars will be hybrids and more fuel efficient cars.
In 5-10 years those cars will be undriveable and costly to repair, due mainly to current manufacturing techniques. Cars are not designed to last more than 5 years/200000 miles.
"Gee, this used prius looks good, only $1999! Wait. It's battery pack's dead....and the petrol motor's a little smokey...What? $4K for a new battery? $2K to rebuild a pokey 1.3l motor? Forget it."
It's the multi-platform nature that "cripples" VNC compared to RDP.
Say you want to display a window.
VNC watches the server screen and sees a big chunk of pixels change, sends the completed change as an image (with compression, etc) to the other end.
RDP sends a message (with compression, etc) saying, "Draw a window at co-ordinates x,y , size x,y on your desktop. Put in 6 standard text widgets, place the cursor in the second one, blinking slow."
So, two questions: - Which one do you think takes less bandwidth, ans seems more responsive? - Which one do you think works with umpteen different display servers, window managers and widget sets?
You could make VNC as fast as RDP, but you'd just end up with RDP.

0.05% legal limit, which equates to roughly 3 beers an hour for the first hour, then 1 beer an hour after that.
Just about every DUI results in a loss of licence for at least a couple of months. Caught driving while suspended? Whoops, 12 months no licence for you, dumbass. Driving again? Kiss your licence goodbye, permanently. Sure, you can apply to have it back in a few years, but you'll need a damn good case.
Random roadside breath tests, pretty much every couple of days where I live (town of about 25K people). So I get pulled over maybe once every couple of months. Got pulled over at 730 am one morning after coming home from night shift. Blow in the machine... 0.00 (we hope!!), off you go again. Gory ads on the TV showing dead young mums covered in blood after getting hit by a car, all from the drivers POV (after 8.30pm, when the kids have gone to bed, of course.) They advertise on long weekends that they'll be out in force doing a blitz on drink-driving/seatbelts/speeding , for crying out loud.
And there's *still* people out drink driving. Maybe we should start tattooing repeat offenders on the forehead "Unable to control urge to drink"
You don't have to kill the engine - just throttle it's fuel injection so that it barely makes idle. Then when it's speed reaches zero, switch it off.
A lot of heavy vehicles with Detroit Diesel or Cat electronic injection do this if you have a major fault (overheat, loss of oil pressure) - they ramp down available engine power and then cut off after 30 seconds. It generally gives you enough time to say "WTF?" , look at the gauges/lights to see what's up, and pull off the road.
I had a car alarm that did the same sort of thing - when it was on it would allow the car to start and run for 3 seconds, then would cut out the ignition a random few seconds after that. The theory was that thieves would believe that there was something wrong with the car (it did start, after all) and abandon it for easier targets.
800nm diameter? That doesn't make any sense! 800nm is close to visible light wavelengths. Could be tricky to design a camera when the wavelengths you want to record are the same size as the camera. Hmm, and a quick scan the linked articles don't really mention 800nm.... Was someone just pulling that number out of their ass, roland?
And please stop linking to your summaries of the artice, which simply cut'n'paste the first linked article with a few bits of filler.
I give the USA twenty years, tops, before it all goes to shit, snow-crash style. This particular passage in that book struck a chord with me - I believe it's only a matter of time.
" But when a businessman from New Jersey goes to Dubuque, he knows he can walk into a McDonald's and no one will stare at him. He can order without having to look at the menu, and the food will always taste the same. McDonald's is Home, condensed into a three-ring binder and xeroxed. "No surprises" is the motto of the franchise ghetto, its Good Housekeeping seal, subliminally blazoned on every sign and logo that make up the curves and grids of light that outline the Basin.
The people of America, who live in the world's most surprising and terrible country, take comfort in that motto. Follow the loglo outward, to where the growth is enfolded into the valleys and the canyons, and you find the land of refugees. They have fled from the true America, the America of atomic bombs, scalpings, hip-hop, chaos theory, cement overshoes, snake handlers, spree killers, space walks, buffalo jumps, drive-bys, cruise missiles, Sherman's March, gridlock, motorcycle gangs, and bungee jumping. They have parallel-parked their bimbo boxes in identical computer designed Burbclave street patterns and secreted themselves in symmetrical sheetrock shitholes with vinyl floors and ill-fitting woodwork and no sidewalks, vast housefarms out in the loglo wilderness, a culture medium for a medium culture.
