  • What technology are you excited about?

  • This is the key to so much. Worried about Nestlé monopolizing freshwater? With nuclear fusion we can just take any old seawater and remove the salt. Worried about the war with Russia? With nuclear fusion we can become independent of all gas from Russia and cut off one of their biggest income sources. Lots of special materials are expensive because electricity is expensive - with nuclear fusion electricity is practically free. Over time we can get rid of any coal plants etc. that produce CO2.

  • I'm thinking of file compression formats like Zip, LHA and ARJ, which would work particularly well if the image was not dithered and used run-length encoding (e.g. the PIC format of the Atari ST). The PNG format still uses the deflate algorithm which is essentially identical to the compression used by PKZip in 1991.

  • At the time when dithering was commonly used to achieve the illusion of more available colors, i.e. the 80s and the first half of the 90s.

  • For some reason I find glitching physics in games to be hilarious. This clip from AC4 had me wheezing.

  • It's really only helpful for formats that will be directly read by hardware (the video chip) and where the "compression" ratio (I would prefer the term quantization) needs to be fixed. For file compression, which was quite mature but CPU- and memory-intensive at the time, the dithering only makes it more difficult to compress further.

    Compressed textures on modern GPUs actually use similar compression: a color palette followed by indexes into the palette. But that's done per 4x4 pixel block.

  • Why are people who make questionnaires so bad at making questionnaires? It's baffling. This post is particularly glaring but I always find stupid errors or assumptions like this.

  • I think such projects don't exist precisely because Mozilla is still developing it. If Mozilla abandons Firefox then someone else will take up the torch.

  • I believe the Firefox development organization could be a lot leaner, and not all of the work has to be directly salaried. There are plenty of huge open source projects that are progressing fine without being run by a single for-profit company. E.g. the Apache ecosystem, the Linux foundation projects, FreeBSD, etc.

  • Practicing loving-kindness meditation and trying to find an interest in the lives of others. When you feel a genuine interest in learning about the lives of the people you meet and are not worrying about your own self-image, people are less scary and easier to talk to.

    I used to be afraid of people thinking less of me for asking stupid questions, but now I don't care so much about what they think about me. I come from a mindset of compassion rather than fear. It turns out that people generally prefer dumb but interested over insecurity.

  • The biggest scandal we had in all of my school years was that when I was 17 there was a girl in my class who was dating a 25-year-old. Nobody was ever interested in anyone's dad.

    Come to think of it, we barely ever met anyone's dad. Why would we?

    Why is math a hard subject for most people?

    Jump

  • Mathematicians are shitty communicators who like feeling special because they can understand their obscure language.

    I'm a programmer and in this field there have been tons of books published, conference talks, and heated internet arguments about how to make your code as readable as possible: formatting, function length, naming of variables and functions, keeping number of cross references low, how to document intent, etc. Mathematicians do none of that - it's all single-character names (preferably from the Greek alphabet to complicate it further) and they rarely communicate intent before throwing formulas at you. You can easily tell when a mathematician has written code because it's typically hot garbage in terms of readability.
