Comment Re:Why do they fail though? (Score 1) 151

As another already commented, the devil is in the details. He briefly mentioned longevity, but I'd like to elaborate on that. Some materials, like silicon, can carry 4 times tge charge of regular batteries, but they tend to swell when they take up the charge and shrink when they lose it. Apart from the mechanical problems, this is a major limitation of the amount of cycles that the battery can withstand. After a few cycles the material is so worn that you lose all the benefits. A material may look so awesome on paper or in the lab so that it causes press releases and hype, but all that vanishes the closer you get to production.

Also, it's hard to get a "perfect" material that can cary more charge, for longer time, last more cycles, is cheap, non-toxic, non-explosive or a fire hazard, does not overheat, compact (in terms of weight and/or volume), easy to process and manufacture into an actual battery... you see where this is going... Everyone's looking for this elusive material, and everyone wants to show they are making progress in order to raise more research funds, thus the press releases and the stirr.

For what is worth, movies are not shot in one go (except Russian Ark), but are composed out of several "takes". This is an axample where a technical limitation will actually teach you better cinematography skills. But then again you wouldn't be using your phone for shooting a movie. Unless you are recording your kid's shool play, in which case you should go out and buy a camcorder already.

Meh. I haven't seen someone carry around an extra battery in a LONG time. Also, the internal SSD is large enough for most people. Although I like to have them as options in my Note 3, they are unimportant for 99% of the buyers out there. Nobody will notice they're missing.

Who said they want to get rid of corruption, in general? SAP is a German company and in Germany it's perfectly legal to bribe a foreign official. It makes the exports more "competitive" and it's good for the German economy. Anti-bribery laws is Germany are only concerned about bribing German officials, thus putting the country at an advantage, not a disadvantage. See what state Greece is in? Maybe you want to read on the bribing of Greek officials by Siemens. (Disclaimer: I'm Greek living in Germany)

You need to look into the problem at hand more closely! The software plays a very important role. Perhaps it can benefit more from a GPU cluster rather than a CPU cluster? Can it benefit from the instruction set of the latest Xeons or will the older (and now cheaper) generation suffice? CFD simulations are quite memory-hungry, so 3 GB per core is pretty standard. Also, you need to make sure that the cores can talk to the RAM efficiently, so definitely pick a CPU with 4 memory channels. After 6 cores per cpu or so the communication between the cores and the RAM becomes the bottleneck, so don't stack too many cores on the chip. Dual socket motherboards and CPU combos are also pretty cost effective. Also, users tend to suck the performance advantage of such a machine quite rapidly, so you shouls also plan for the future.
