    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 descript…

    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 b…

    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" fusio…

    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 a…

    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 thi…

    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.

    As long as you say it, you're okay with slavery when it's for the right person.

    What should it do when you call an async function from non-async? Block?
