It's not quite an order of magnitude. In most regions, the cost of the batteries for a given daily power drain are going to be less than the cost of power. In that a kilowatt hour of batteries is $200, and in most places you'd pay a good deal more than $200* for a kilowatt hour a day for five years. Of course, there's also the costs of the panels and all that other equipment, but I'm just saying that your component pricing seems out of whack.

EDIT: This is reportedly what Tesla pays for batteries now, pre-gigafactory. By the time anybody tried to actually build a battery-backed solar datacenter, costs would be lower. They seem to drop at ~6-8% a year

I've got a MacBook Air. It serves as my secondary PC (as a Windows user on the desktop and a Linux user on the server). Of all the apps that are installed on my Mac that aren't from Apple, I think only a single one of them (MPlayerX) is from the app store. From Dropbox to VLC to Chrome to Creative Suite to DiskInventoryX to SmoothMouse to Steam, almost nothing is available in the app store.

In fact, some things that I run on my mac (like Civ 5) through other "app stores" (like Steam) are available in the Mac app store... but are essentially crippled because they don't support multiplayer with the regular version of the game. And even though I bought the game, I would have to pay for it again to get the App Store version. Which, I wouldn't do, because I like actually being able to play multiplayer games with my friends who bought it like everybody else (through Steam).

They're throwing lots of cores at the problem *because* of their very low IPC. The fact that they took chips with poor IPC and then gave them very low clockspeeds just made matters worse.

Sony/Microsoft went with AMD because they were willing to do custom designs, with single-chip solutions, at a good pricepoint. Intel is unwilling to do custom designs, and they would have had to do a custom design with multiple times more graphics EUs to satisfy Sony/Microsoft.

In my first year of computer science in CEGEP, we were 60 students. 2 of them were women. They accepted pretty much anybody who applied based purely on your highschool grades. Right off the bat you've got a 97% male program, and there was no bias in that selection either (for what it's worth, the person deciding on applications was female). Women simply did not apply for the program in the first place.

It's always been obvious to me that the reason that there are so few female developers has little to do with hiring practices and a lot to do with the lack of interest in computer science among women. You just have to look threw a stack of CVs when people apply for jobs at your company for it to be obvious: when there are so few CVs from women in the pile, statistically you're not going to hire as many of them.

It's not, but the statement was "Macs before 2009 can't run the current version of OS X".

The reason the earlier Mac Mini isn't supported is apparently due to the lack of a 64-bit driver being available for the Intel GMA 950 used. It's probable that by the time a 64-bit driver was needed (the move to Mountain Lion) in 2012, those mac minis had been out long enough that they didn't consider it worth writing a new driver to get them supported.

There are, however, workarounds to install Mountain Lion and Mavericks on those machines. Unfortunately, while it's possible to get Mountain Lion running relatively stably, Mavericks isn't very stable on them.

Those older Mac Minis aren't entirely useless, though. They run Windows 7 and 8 just fine via BootCamp :)

If memory serves, when Apple's A7 came out, benchmarks showed it as being faster than low-end Atom processors, and there are faster ARM chips on the market than the A7 now (including Apple's own revision of it, the A8). There's a lot of overlap in the performance spectrum between high-end ARM and low-end x86.

Any given program, when running, is obsolete.
