You're not serious right? MacOS is very much a tightly integrated system.

HURD is functional, it's just not really used by anything or anybody, so it's missing a lot of features. It's also to some degree rotting, last I checked it still was limited to i386. But HURD distros do exist in variants lik

Not sure how it generates power? Pu238 is a very strong alpha emitter. Alpha particles (helium nuclei) are really big and charged, so they don't travel very far and deposit all their energy near where the decay occurs (as opposed to d

I doubt it. Apart from the fact that at least I find replace mode useful, I think their main reason is not just because most people don't use it, but also because ex mode behaves inconsistently.

Absolutely everywhere, it is a common subproblem in many many algorithms. For example, the basin hopping algorithm (sister of SA) solves one at every step. A specific example is in image deblurring via Tikhonov regularization, which involv

Uh most recent Nvidia GPUs support double precision, albeit at a speed penalty. And they are using a Tesla card in the article. It says they are using a K10.

I'm pretty sure you can reduce the entropy of the output by saturating the processor or memory. If the various accesses are being spread out more because other processes are executing then you're going to have substantially less

It's either Infiniband or some other high speed interconnect. It's not exclusively Infiniband, for instance the Chinese developed their own, but it's usually something similar.

FPGA has potential for simulation too from what I know, but I honestly don't know enough about them to comment intelligently about them. I expect most people will use them via an intermediate abstraction layer, as from what I know they

This is not exactly true, most of the ones I know are running straight up Linux. Titan, for example, runs basically SLES on the login nodes and Compute Node Linux on the compute nodes. CNL is a pared down version of Linux, but it definitely

The Bessel function(s) are pretty difficult to calculate and generally have to be calculated numerically via any of several methods. Looking at the numbers you posted, I'd say that Jmat is probably using a different algorithm and/

While arithmetic is almost undeniably necessary for programming (and even some more advanced topics like basic linear algebra), I think the core argument here is more about "higher" math. Stuff like how to reason about abstraction

A truckload isn't all that much. I doubt the truck in the article was carrying more than a couple grams of the actual material. The lab grade sources we use (that are considered safe to handle as long as you don't eat them) are on

I wouldn't say Wolfram himself has a large following in the sciences. At least in my area (math and engineering) he is actually widely and heavily criticized. However, some of the things his company makes are widely used. Mathematica i

It is difficult to detect unless you know to look for it. The symptoms are pretty generic and easily misdiagnosed since few doctors would be expecting it. Still not that great of an idea in such a high profile case, but it has the potentia

At times numpy/scipy/matplotlib have proven pretty troublesome to install with pip. I think they have it working now, but it's still not 100% reliable.
