My point was that even in the immediate area surrounding a nuclear plant the temperature isn't significantly affected despite the fact that it's literally pumping two order of magnitude more thermal energy into the environment.
Ice block cooling is fairly common in commercial and datacenter cooling systems in areas where there is a large discrepancy in pricing between peak and off peak electric prices. Also it's rarely water that is used as the heat transfer media, it's usually glycol as using water would result in clogged pipes because it would freeze in the portion of the pipe in contact with the ice block.
833 tonnes of ice over 12 hours is 76.5 tons of cooling per hour, that's less than a midsized datacenter. I can't see how that can possibly have any meaningful effect on something the size of a city.
ARM11, specifically ARM1176JZF-S 700-megahertz which is a component of the Broadcom BCM2835 SoC.
While it's cool that they got the cost so low I'm kind of sad to see all those SMC's, kids today can't get into building electronics because so much stuff has gone to stuff that you just can't solder by hand. Yes, I know you can still use microcontrollers with breadboards, which is cool if you want to make a simple robot, but stuff like building your own computer that you can hook up to your TV and use like any other computer would be very cool as well.
No, there are 16 integer pipelines with one scheduler and 4 logic units each, 16 128bit floating point units that can also be combined into 8 256bit units, and 8 fetch/decode units. This is not a MCU, it's one chip with the above mentioned components. Whether it's 16 cores or 8 or 4 modules is kind of academic unless you are trying to optimize a scheduler for it in which case the label's still don't matter, only the actual implementation and achievable performance matter.
Like the example of pipelines from the article this misses the fact that the primary cause of drag in such situations is not the surface roughness of the material but rather the turbulence of the boundary layer between the surface and the laminar flow. In fact a rougher surface can actually improve flow performance by decreasing the turbulence (ie a golfball).
Ok, so the entire industry is worth ~$20B, still hard to see how they can lose $12B a year just to piracy and be collectively worth only $20B. I mean that puts the P:E on just lost sales at 1.5, about 10x less than what a slow growth bluechip is worth. Hell at $20B the tech companies should just pool a part of their pocket change (cash reserves) and buy the whole industry and stop the shenanigans and let people start using music in a way that isn't stuck in the era of wax cylinders.
Rapidly? Thor lives on in the first stage of the Delta II. Titan was also a backup program Atlas as the next generation ICBM platform. It wasn't until Saturn and Polaris that the programs really diverged as shrinking warheads meant that the military could transition to SRB's which have all sorts of advantages for a fleet of standby missiles.
Yeah and the political problem goes beyond money. They aren't allowed to take any significant risks because any failure is seen as a major political risk which might get their budget further cut. They also aren't allowed to choose their own designs based on technical merit, they must use SRB's because ATK gives large donations to the campaign of the senators and congressmen from Utah.
You're an idiot. Our network engineer, telecom guy, and email admins are all ex-military and not only are they all above average intelligence but their disciple and calmness under stress are all great advantages working in a small IT group with fairly significant expectations from the business.
The F111 flew over 4,000 sorties with 6 combat losses over Vietnam, the best record of any aircraft other than the venerable B52.

It wasn't a $500 toilet seat, it was a custom crafted fixture to enclose a new tank that a toilet seat attached to and the reason it was so expensive is that a new mold had to be built and they were only producing a run of a few hundred units. Likewise the $500 toolbox was a soundproofed unit designed for working outside the acoustically shielded portion of a line of billion dollar nuclear submarines with a handful of units produced.
All I have to say is $85B in cash and liquid assets, that's almost 1/3rd of Microsofts entire market cap. I wouldn't count a company with the kind of innovation of Apple and that kind of war chest out of anything anytime soon. If they wanted to win the tablet segment all they would need to do is price a basic ipad at $250-300 and everything else would sell essentially zero units. There's even some indication that they are willing to do that with the recent downward pricing of the old iphone models, though there's certainly less after sales revenue to be had in the current tablet market than there is in smartphones.

Any barbarians invading the US mainland are going to have one hell of a time given the fact that there are something like 1.1 guns for every man, woman and child in the US, far outstripping places where the worlds largest and most well funded military has been bogged down for a decade.

Will the Army let them? The last time the Air Force talked about abandoning the A-10 the Army threatened to restart the Army Air Corps so there would be someone to fly the tubs. Supersonic fighters dropping bombs from 10k feet isn't exactly the same role as the A-10.
Here's a pretty good breakdown of numbers. His results for hydro are lower than I've seen from some studies but the gist is the same, nuclear is incredibly safe.
No, deaths per MWHr for nuclear are by far the lowest of any power source available, including things like wind, solar, and hydro. This is true even if you take the worst case cancer numbers which are probably off by at least an order of magnitude.
Actually, the field mice around Chernobyl have a much higher rate of mutation including a 300% increase in fertility rates compared to those outside the exclusion zone which more than makes up for the slightly increased morbidity rate. It was one of the more interesting tidbits in a recent PBS show on research in the exclusion zone.
SATA is not Enterprise, labeling a SATA NL drive as Enterprise is lipstick on a pig. Heck even NL SAS drives are only Enterprise grade in certain scenarios. FC, SCSI or SAS drives which are rated for 24x7 100% duty are what I consider Enterprise class drives.
Actually, VMWare has the solution for Android, run a hypervisor and have two Android installs, one a corporate locked down environment where corporate data resides, and a consumer install where the users can install whatever software they want. Right now there's like two devices available (none in the US AFAIK) but AT&T has like 6 coming in the next few months.
How is 5% versus 2.75% AFR not any faster!?!? Add in my experience with thousands of FC/SAS/SCSI drives with an AFR of 1.5% and the trend is obvious, more expensive drives have a significantly lower AFR.
Note that in the Microsoft's Live@EDU infrastructure, we utilize nerarline 7.2K SATA drives and we see a 5% annual failure rate (AFR), while in MSIT we leverage nearline 7.2K SAS drives and we see a 2.75% AFR therelink
I know from more than a decade of experience that real world enterprise SAS/FC/SCSI AFR is ~1.5%. AFR and drive rebuild time also affect the likelyhood of catastrophic data loss. Plus failing drives are by far the greatest cause of unplanned downtime in my environment, overshadowing software faults by ~10x over the last 5 years for downtime caused. Drives that just fail are no big deal, it's the ones that start to fail and puke all over the bus that cause issues, fewer failures means fewer chances to screw up the bus and cause downtime.
