Toshiba 4S (Super Safe, Small and Simple)

"The actual reactor would be located in a sealed, cylindrical vault 30 m (98 ft) underground, while the building above ground would be 22×16×11 m (72×52.5×36 ft) in size. This power plant is designed to provide 10 megawatts of electrical power with a 50 MW version available in the future."

> 2,351 megaflops per watt

I never understand this unit. That's in effect just "megaflop/joule". Why not use that?

An interesting point from "Energy Oddities, Part 2: Why Green Computing Is Odd by Kirk W. Cameron (IEEE Computer, March 2013)":

Consider the power profile of an average system with two 4-core Intel Xeon processors under various loads. (...), the power consumption varies according to the system’s use of memory, disks, and processors, fluctuating from about 120 W at idle to more than 200 W under an intense CPU workload. This constitutes about a 90-W or 42 % up-swing in energy use, which typically occurs in less than 50 ms.

Now, consider a datacenter with 1,000 or 10,000 of these types of systems. The largest possible increase in power consumption in less than 50 ms in the case of 1,000 systems is about 90 kW, and in the case of 10,000 systems, it is about 900 kW (...) power companies prefer steady power consumption to the impractical nature of spinning generators up and down and the high cost of overprovisioning. So, for a single datacenter with less than 10,000 systems using a typical Xeon server, these energy swings are real but not troubling because power providers operate in the range of tens to hundreds of MW.

General-purpose graphics processing units (...) engines consume significant amounts of power, ranging from 30 to 200 W per GPGPU. (---An example--) system’s baseline power increases about 40 watts with the GPGPU card installed. Furthermore, under a matrix multiply workload running on the Nvidia card, the power can fluctuate as much as 62 percent, or 270 watts, in less than 50 ms.

What are the implications for the datacenter? For 1,000 systems, swings of about 270 kW would occur, whereas for 10,000 systems, swings could exceed 2.7 MW. These are big numbers, and we have no idea whether they will wreak havoc on the power grid. Certainly a 2.7-MW swing is less than ideal from a power company’s perspective. (...) If we extrapolate the data from our system to 10,000 nodes with three GPGPUs each, swings could exceed 8 MW.

(...) individual datacenters and colocation facilities, such as those Google and Facebook are building, are getting larger. For various reasons, companies are clustering datacenters in certain areas—for example, Salt Lake City, UT, and Herndon, VA. With these types of observed fluctuations across multiple datacenters, potentially dramatic power swings in the tens of MW can place additional strains on the power grid.

"And then find out that it's not working due to a printing error in the book and you have no idea what the correct value should be?"

This. Much later did I realize that, had those editors not been clueless brats they would have included error-detection and possibly correction codes.

To be fair, books about arcane things like coding theory were hard to come by, but I'm sure there must have been articles on this in IEEE Computer or CACM, which did arrive in the mailboxes even in Yurop.

Re: @AndrueC

> boot to explorer as the shell

Can anyone enlighten me as to what people consider a "shell" in Windows?

In Unix, the "shell" is the command interpreter (the program) input/outputting to an interactive text interface (in olden days, a line printer complete with fanfold (hell yeah!), nowadays, some window in graphical user interface)

Clearly that's not it.

The "Windows shell" seems to be something on a sliding scale between the whole UI system (corresponds to X, swappable in Unix, not so much in Windows unless you want to look into the kernel), the look and feel of it (Gnome, KDE, XFCE) and some file navigator / application (Dolphin, Konqueror etc.)

Re: IANAE

> I think the money would be parked in an account in Ireland?

Which would be cool too. That would be savings. Savings decrease the cost of borrowed money (i.e. interest rates). Hence investments can take off. Of course, in these fairy tale days of neverending bubbles, interest rates are kept low by ministerial decree followed by printing press noises, which causes inflation, puts the economy on amphetamine (no teeth after a decade or so) and nukes your pension scheme. But hey, that's pretty complex for people to understand. And the minister can take a hefty wank because he "helped the economy", natch.

Re: IANAE

Of course.

Someone from dim & slow-witted country thinks that people have a money printing machine like a Central Bank and thus should be forced to keynesianistically pump it out to increase GDP. Similar ideas can be heard from 5-year olds and Krugman. Doesn't mean they make any sense.

Guess he's just shilling for the software rent seekers though (who brought us such nice presents like software patents and similar rapes of Joe Public) who have marginal production costs anyway, so don't expect a job to be created for a guy to watch the shrink-wrapping machine if you shell out for overpriced buggy stuff.

"I do think that when history looks at this, they are going to contrast the behavior of James Clapper, our national intelligence director, with Edward Snowden. Mr. Clapper lied in Congress, in defiance of the law, in the name of security. Mr. Snowden told the truth in the name of privacy. So I think there will be a judgment, because both of them broke the law."
