Comment "Computer" (Score 4, Interesting) 81

"Computer", actually, has the meaning: "Machine that performs computations". In that sense, this contraption truly is a computer. It probably only has a memory size of only a few bytes, in modern terms, and can only do a few FLopS also. Yet, it is a computer, in all senses of the word.

Funny. I always thought of Michelson as of one of the two guys involved in the "failed" mirror experiments that allowed A. Einstein to come up with the theory of Special Relativity. Not so, it turns out now: the guy was an accomplished engineer. How great.

about Windows phones, anyway? The huge capital destruction operation that the Nokia takeover amounted to wasn't enough, obviously: MS needs to sink even more cash into a non-existing market: Windows phones. Ain't gonna change anytime soon. Reason : there is no fucking **innovation** going on at MS. Just marketing. Meh.

Submission + - Aeron - or: How to Take Distributed Logging to Extreme Perfs (youtube.com)

vikingpower writes: After having been a contributor to the LMAX Disruptor, an extremely fast RingBuffer pattern, Martin Thompson is at it again,together with two other guys from the London High-Performance Computing scene. This time with an open-source library named Aeron, after a Celtic god. Aeron does message-passing over ( mostly ) UDP, that is: on level 4 of the OSI stack, and does it extremely well. Aeron is written in pure Java 8, and exploits that version's newly introduced lambda expressions. The ideas at the core of Aeron and of the somewhat older Disruptor pattern hail from Mechanical Sympathy, a way of designing and coding aiming to exploit the multiple caches of modern processors as much as possible. Mechanical Sympathy on Google Groups shows, by the questions and comments alone, what extreme perfs can be reached on COTS hardware, in pure Java.

Disclaimer: the author of this submission is in no way a direct stakeholder in Aeron or LMAX, just an interested user.

For example, one of the ThinkPads with carbon casing. I speak from experience: I have one, and have been lugging it everywhere. The things simply never break ( hear identical experiences from other users ). With one new internal and one new extra battery ( goes into the CD/DVD player slot ), in low-energy mode and BlueTooth / WiFi off, you'll last for 8 - 10 hours.

Take a compact course book on tensors, and Einstein's General Theory of Relativity. You'll need to assimilate the first to grasp the beauty of the second. If you only do the former, you'll come back with an important and valuable mathematical skill: tensors. If you go on to do the second, you'll be an intellectually much richer person when you come back, and it will change your look upon our universe.

Philae has separated from Rosetta, and is now sailing at 18 cm/s toward the comet. One of its rocket engines, on top of Philae, does not work. This engine is intended to push Philae against the comet; we now face the possiblity that Philae gently "bounces back" into space, because of the comet's very low gravity. Tension rising here.
