That does sound nice. I think the author would say that if it's part of your annual performance review, then you are being paid to do it. That's the real test, not the job description, which can't be expected to describe ever

I read the section you quoted as being about saving the day in an incident that's already in progress.

The quoted section is about stepping in early with the right knowledge to fix an incident that's in progress. That is, putting out the fire.

if you have some purported improvement to a codebase that would make it inconsistent, then it's a matter of taste, not fact, whether it is actually an improvement.

You seem to have misunderstood the point being made in the section you quoted. The items are not on the list because it is a list of benefits that accrue to the company from work being legible. "Making money" is not a direct outco

Such optimizations may be forbidden by the fact that floating point addition is not associative unless you tell the compiler not to worry about that (I believe)

I can't see why a jitter plot with dark lines marking the quartile wouldn't be strictly better for this.

I doubt they have achieved any fusion reactions. They don't state any numbers on density or temperature so it's impossible to know. But in general plasma is never "caused by" fusion. Creating a plasma is quite easy compa

You don't ever create plasma via fusion, fusion occurs in plasma that has reached a certain temperature and density threshold.

I think the burden of explanation is on the great great grandparent post which proposed an accelerometer "entirely made out of the same magnetic field" which would let it satisfy an equivalence principle for "magnetic force&q

It means nothing for ITER unfortunately. Changing the toroidal field strength implies a totally different plasma size, density, temperature, everything. ITER isn't designed for this strong of fields and the plasma they would confine.

The author of the article is Kim Stanley Robinson, whose Mars Trilogy and novel 2312 include all of the possible in-solar system alternatives you mention and more.

The FFT is rarely the only thing you're doing, so at the very least you get to keep the data local if it was already on gpu.

It didn't, it did the subtraction in lbs and got the right answer, the off-by-one is due to rounding.

Matt Levine suggested that the chaos after opening was mainly due to market orders executing at ridiculous prices. Like, a limit buy for half the "real price" is the first buy order to get in the door, and that gets matched with a

The speed of sound is the eigenvalue of a particular matrix (the "flux Jacobian") in the Euler equations, the 5-component system of partial differential equations that describe gas dynamics.

One way to understand where the formulas come from is the power series of e^x, remembering that that function is (can be) defined as the function whose derivative is itself. Sin and cos are functions whose second derivative is -sin and -cos

The heat flux management from the plasma is certainly not dumb engineering, true. However, the actual heat transfer technology is, I think it's fair to say, "dumb" compared to all of the plasma physics that has to enable the
