The thing about scientific computing is that scientists like to write MPI and Fortran. They just love that shit. And they are traditionally really resistant to any new programming model. So when you tell them they need to start using XYZ instead of MPI so their programs can actually complete at exascale *before* hardware failure, they get unhappy and instead implement things like checkpoint/restore that takes 70% of the runtime. Source: I work in HPC.

Changing from FORTRAN would require us to actually try to comprehend decades worth of scientific data stored in FORTRAN data files. Ain't no one got time fo' that.

I remember seeing a whistle device that you attach to your key ring. When you lose your keys, you whistle and your key ring beeps.

Yes it is a problem that can be solved with very simple analog electronics. That was my first thought when I read the summary, but I guess that wouldn't be cool today.

WTF: SIP is an IETF standard, so these people should not be holding any patents, otherwise it is another useless standard. It would be like if http protocol was patented and they required you to pay to implement it.

Seems the patents aren't on the SIP as such, but rather on SIP trunking. Some other posters have been touching on this, but it is not stated clearly in the summary or in any posts form what I could see.

Actually, neutrinos do arrive slightly faster than light from supernovae. Space isn't completely empty --- tiny amounts of interstellar gas give it a refractive index slightly higher than "perfect" vacuum, which ever-so-slightly slows down light. Neutrinos interact far less than light with matter; so, a supernova neutrino going at very nearly the speed of light can outrun a photon through space. In Supernova 1987A, neutrino detectors saw neutrinos about three hours before light reached earth's telescopes.

Very informative, thank you. (No mod points today)

Submitted by hcs_$reboot
hcs_$reboot writes "The well known Fukushima daiichi power plant suffers from a power black-out since yesterday Monday evening (local time), leading to stopping the flow of cooling water to four fuel storage pools. However, "No need to worry, temperatures will remain in the safe range for 4 days" said the also well known company in charge, Tepco. The cause of the blackout is still being investigated."

Yes. Seconds are part of the official SI standard. That makes hours "metric". You basically blew any geek cred with that question.

Sheesh, I was trying to make a joke about the mixing and matching of units and decimals in the imperial system by parent. Then as the AC Below states, seconds are metric (SI units) but hours certainly are not. So guess we both need to hand over our geek cards to the AC huh? You because of failing on SI units, and me because failing to make a proper joke. :-)

So how well does it make popcorn?

Sheesh, and you people have the nerve to call yourselves nerds. A quick back of the envelope calculation:

Laser output: 50kW Average microwave oven: 1kW Duration of popping: 2 m. 30 sec. = 150 sec. Therefore, 1 bag of popcorn every 3 seconds.

House volume: 2000 sq ft * 6 ft high = 12000 cu ft Volume of a bag of popcorn = 0.25 cu ft Therefore, 144k bags of popcorn would be needed.

(144k bags * 3 sec per bag) / 3600 secs per hour = 120 hours

Hope Val Kilmer isn't in a hurry.

Would that be metric hours?
