with their Fifth Generation Computer Systems initiative. They demonstrated that just throwing money at the problem doesn't solve it.

We need strong encryption for use by law-abiding citizens, and weak encryption for use by criminals.

TSX was disabled in Broadwell and early Haswell chips due to a bug. Do these new Broadwell-U have the TSX fix?

I have an experimental workload for which TSX would be very helpful, due to a need for atomic reads and writes of unaligned 10-byte data items. As far as I can determine, x86 provides no other way to guarantee atomicity of an unaligned 10-byte read or write.

Wrong. We've produced "...machines that exhibit the agency and awareness of..." a worm: http://www.smithsonianmag.com/...

Perhaps. IEEE Spectrum credits Maruska, as do several other histories of the subject.

Maruska seems to have made the first working violet LED. Some people claim that it doesn't qualify as a blue LED, but as far as I know there's no agreed-upon hard distinction between violet and blue. Maruska developed the right materials and process to make it, even if RCA pulled the plug before he had solved all of the problems necessary for commercialization.

The blue LED was invented by Herbert Paul Maruska at RCA in the early 1970s using Mg-doped GaN. A different one, using SiC, was invented at Cree in the late 1980s.

Yes, but good luck actually buying the A1100 reference board today. It's easy to offer a lower price on something you're not actually selling.

The 100 MHz Quark MCU is 32-bit. The dual-core Atom CPU is very likely 64-bit. There were some early Atom chips that had 64-bit disabled, but none of the recent ones have.

$49 only gets you the Edison module, which is useless by itself. You also need a base board of some kind. The Edison module with the Arduino-compatible base board shown in the photos will set you back $99. Still a pretty good price. 3x more expensive than a Raspberry Pi, but it is a lot more capable.

I'd get more excited about a 64-bit ARM embedded board, but those aren't available yet, other than a $6000 development board from ARM.

Not all of the code on GitHub is open source, but the majority is -- handy, when that means an account is free as in beer, too.

I'm not privy to any details of GitHub's finances or business model, but most likely it's a good thing that there are non-open-source projects using GitHub, because that's probably what's paying for the free open source use. I've recommended to several clients developing proprietary software the use of GitHub rather than running their own in-house repositories, because the interface is easier for them to use and they don't need as much in-house expertise to manage things. Because Git is distributed, they could of course do both, or easily transition away from GitHub later, and that's a selling point.
