   This is the wrong way to look at it. If a textbook is bad, or is good but too difficult (i.e. bad) you will stop reading it. The alternative to self-studying a good textbook isn't studying a bad one, but studying none.

   Exactly. It's very hard to judge how hard it is to understand something when you already understand it. This is also why video games with puzzles need extensive play testing. Because the puzzle designer, already understanding how to so

   Exercises in textbooks usually focus on proofs, but mathematics isn't just about proving theorems. Mathematics is also about: 1. Understanding mathematical concepts (e.g. what is an "acyclic" relation? What is KL divergence?)

   Well I disagree with that. It's two different ways of mixing colors (additive vs blending), with different results and different requirements.

   > Saturation can't be controlled on a per-pixel basis because, per the article, they're tuned to a specific wavelength at any given time. Where does the article say this? I couldn't find it.

   That's not true. Dithering can be used in emissive screens, but dithering is not additive. If you mix red and green with color blending (e.g. by dithering), you get less red and less green in your mix, and therefore the resulting mix (

   You can dither not just in print but also on illuminated screens. For example: http://caca.zoy.org/study/out/lena6-1-2.png This picture has only pixels of the aforementioned eight colors.

    No, normal monitors use additive color mixing, but dithering isn't additive, it's averaging. With just red, green, blue, black you couldn't dither cyan, magenta, yellow, white, just some much darker versions of them. E.g. you

    You are confusing the cosmological principle with the uniformitarian principle [1]. The cosmological principle concerns the large-scale distribution of matter (not of laws) in the universe, and that is something we arrived at empirically,

    There is also an interesting relation between the second law of thermodynamics and the cosmological principle (which says "the distribution of matter is homogeneous and isotropic on large scales"): The second law of thermodynamics

    The Snapdragon 8+ Gen 1 solved it by switching to a better TSMC node. The Gen 2 increased performance (on the same node) and got again somewhat less efficient.

    Because it indicates that OpenAI has achieved a significant AI breakthrough. It seems inappropriate that this post is no longer on the frontpage.

    This also explains why drivers for new PC-GPUs (Intel, Qualcomm) are so "bad". They probably aren't that bad, they just don't contain hacks for decades of games like Nvidia and AMD.

    Well, the term "tensor core" is only used by Nvidia, and Nvidia does make Arm SoCs (Tegra), which may help you find the answer.

    The Nintendo DS didn't need any peripherals, in contrast to smartphones, so this comparison seems misplaced.

    A 1000 hour life span was a reasonable trade-off between longevity and power efficiency. See https://www.youtube.com/watch?v=zb7Bs98KmnY

    tl;dw: No, it wasn't an evil conspiracy; a 1000 hour life span was a reasonable trade-off between longevity and power efficiency.

    There is little doubt that it will do so in a few months. The main engines have already been tested successfully on Vulcan, a few months ago.

    That's just for small launchers and the funding is only 25 million in total (to be divided by several companies) which is orders of magnitude lower than would be required for a partly reusable Ariane 6 replacement.

    Ariane 6 isn't significantly ahead of New Glenn in terms of time. Probably a few months difference for date of first launch. Just as Vulcan launched a few months ahead of Ariane 6.
