    Solar panels work just fine in the winter, unless they are snowed in of course. He should get wind and water power too. He should also get satelite backup internet.
    Whatever, he's Gen-X, dweeb.

    That line of code can be used as a negative example in any clean code course.
    More like optimizing for -O0 to me by replacing multiplication then division with a shift and add. Not as bad as poor variable naming.

    Linus is a Gen-Xer ....

    Not sure what the point of trying to insult someone for their generation cohort is. But if you are going to do non-sensicle things, then at least try to get it right.

    This is just another way of painting people with stereotypes, instead of making an effort to understand.

    Mercedes SLK convertible

    The license plate on Linus Torvalds' Mercedes SLK convertible says it all. The frame running around the outside of the plate says "Mr. Linux. King of All Geeks," but the plate itself reads "Dad of 3." Linus Torvalds has reached middle age, and so has Linux. Nowadays, it's easy to take both of them for granted. But both are still going strong -- very strong.

    The entire schedutil governor is a nasty hack, tbh. (And yep, you're right.)

    If only there was some kind of infrastructure and methodology to automatically test new code submissions and alert the respective parties automatically upon failure!

    Linux development is so archaic it's beyond belief. Submitting anything takes weeks of training and reading before you set up your trees and emails and whatnot. It's a miracle by itself that the whole thing hasn't imploded into itself already. It's like using using a bulletin board system (BBS) for organizing your meetings or something.

    See my comment above. I would never commit that without some inline doc about what that is supposed to do.

    Once again this makes me more curious to see the FreeBSD scheduler compared to the Linux scheduler. Can even be done with Linux code running on both.

    There's not much sun in Oregon during the winters (about 25% of what they get in summer), although of course he could buy tons of extra panels if he wanted to.

    But skipping a week like this isn't a big deal to anyone. He's done it before based on holidays or vacations, and nobody cares. Doing it because of a storm doesn't matter to anyone either.
