Comment Malbolge's useless encryption (Score 1) 729

I find Malbolge's encryption an interesting and nice feature. After an instruction is executed, the value of the current instruction (without anything added to it) will be replaced with itself mod 94. Then, the result is encrypted with one of two methods.

Comment Herding cars (Score 1) 140

Will it not be possible to "herd" an autonomous car, forcing it in different directions simply by driving up very close to it, triggering it to steer away from the approaching object (that is you in your car). If you and your friend sit in two cars, it will even be quite easy I guess. Imagine how annoying that would be to the passengers of the autonomous car!

Swedish Data Center Saves $1M a Year Using Seawater For Cooling 78

alphadogg writes "A data center in Sweden has cut its energy bills by a million dollars a year using seawater to cool its servers, though jellyfish are an occasional hazard. Interxion, a collocation company in the Netherlands that rents data center space in 11 countries, uses water pumped from the Baltic Sea to cool the IT equipment at its facilities in Stockholm. The energy used to cool IT equipment is one of the costliest areas of running a data center. Companies have traditionally used big, mechanical chillers, but some are turning to outside air and evaporative techniques as lower-cost alternatives."

Comment Re:On Goldberg (Score 1) 110

I see your point, but I think you draw conclusions too far from what I wrote. I don't argue that the only quality of an interpretation is to what extent it is along the original intents and lines. Of course there are room for creativeness and vision. Changing from clavichord to pianoforte seems like a good improvement, partly because it makes the sound of this night music softer to the ear, which was one of the whole ideas with the composition. What I meant is that playing what is essentially doubling as a lullaby in a forced or unharmonic manner is just not interesting.

I also see that there is a wide range of ways of defining what is interesting or good in music, or fine arts as a whole. In one of the ends of this range, view with simliarities to yours can be found, that the audience's taste is the only thing that matters (perhaps you could call it "quality by description"). In the other end, there is the view that the audience's reception counts for nothing (perhaps "quality by norm"). I guess your more oriented to the first mentioned end than I am.

Comment On Goldberg (Score 2) 110

This is on a side note. I've been sort of obsessed by the Goldberg variations for years, and of all performers I've heard, I really do recommend Tatiana Nikolayeva (http://en.wikipedia.org/wiki/Tatiana_Nikolayeva). To my ears, she's just outstanding compared to Glenn Gould and the others, when it comes to Goldberg. The Goldberg variations were meant to be played at night, easing the long nights of the insomniac Count Kaiserling, for whom Goldberg worked. I've always thought that the music was meant to be played lightly and sensitively, to be pleasant in the forementioned setting. If you listen to the aria when Tatiana plays it, you will hear an astonishingly soft touch where appropriate, and a really delicate flow. I always thought that this was a really good interpretation of the Goldberg variations. (Glenn Gould - in all his fantastic technical glory - renders it somewhat more forced and hard.)

Comment It may be true! (Score 1) 381

I have a new PC, using the second gen intel i7, and the sandy bridge chipset. I can connect my monitor's HDMI-cable to either the builtin graphical connector (the one powered by the CPU, one of the chipset features), or a cheap Nvidia card which I happen to have. The picture quality is very different: the builtin graphics gives me very crisp and clear picture with bright colours, and the Nvidia card gives me a bit blurrier, darker picture. Same monitor, same cable, different HDMI providers.

Why IT Won't Like Mac OS X Lion Server 341

snydeq writes "InfoWorld's John Rizzo sees Mac OS X Lion Server as a downgrade that may prompt a move to Windows Server. 'Mac OS X 10.7 Lion Server adds innovative features and a new low price tag, but cuts in services and the elimination of advanced GUI administration tools may force some enterprise departments to think twice about the role of Mac servers on their networks,' Rizzo writes. 'Looking more deeply inside Lion Server, it's impossible to avoid the conclusion that Lion Server is not built for those of us in IT. The $50 price tag — down from $500 — is the first clue that Lion Server trying to be a server for the consumer. But the ironic part for IT administrators is that Lion Server actually requires a greater degree of technical knowledge than its predecessors.'"
