    Show HN: Ember – Redshift safe color palettes

    Most color palettes collapse if you've got a strong redshift/nightshift color filter actively suppressing green and blue channels. I made one that doesn't. Ember has terminal, char…

    It's interesting that there are essentially no pictures of the actual device anywhere on this page (except for a lone image, from the back of a user's head, where all you can see i…

    Another ISSDC alum here, but from a little more than a decade earlier. It really was a unique experience. I remember the finals at Kennedy Space Center fully exercised the extent o…

    1 AU is about 8.3 light minutes. So 6k AU is about 50k light minutes. with ~525k minutes in a year, that means that 6k AU/yr is almost exactly 0.1c.

    I used to work on solar power plants and solar tracking technology back in the late 2000s. Even back then, I remember frequently discussing that "eventually panels will be cheap en…

    Lordy, I clicked on this, fully expecting a discussion of a shape-pattern in the board game of Go, and somehow didn't have a thought in my mind for the real, completely different, …

    I tried this once. There was no convincing effect for being able to "detect by feel" AC currents, but you could definitely notice magnetic materials. Maybe the most fun, though, wa…

    https://www.mnist.org I wanted to actually build first-hand intuition on all of the choices around hyperparameter choices, activation functions, network architectures, etc. So I've…

    I'm all for innovative ideas in supporting families and children, but the examples from the article hardly count as "successfully reversing fertility declines". - Nagi, Japan. TFR:…

    That sounds crazy, and amazing. As I've now got a kid of my own who might eventually be interested, could you point out _which_ intensive wilderness school in Washington that is? I…

    It would be interesting to know how the comfort or suitability of these postures is affected by physiology. For example, even the suitability to obtain a deep squat may be affected…

    I'm reasonably good friends with Windell & Lenore, and I think "gobbled up" is not the right way to look at it. It's my understanding that they've known the folks at Bantam for som…

    Doesn't really work this way. A lot of the wonkiness in SR is tied to the fact that the speed of light is the same, measured in _any_ reference frame. So, say you're on earth and y…

    Most useful script I've ever written, and legitimately how I keep track of everything important in my life: #! /bin/bash function todo { if [ $# -eq 0 ] then vim ~/Dropbox/todo/tod…

    One more vote from me for mathacademy.com! For reference, though I now work in tech, I have a physics degree from a top-10 worldwide university, and reviewing linear algebra on mat…

    One more vote for feedly from me! One of the few online subscriptions I don't mind at all paying for. I especially like the ability to auto-generate email addresses for newsletters…

    At the risk of sounding like a shill, have you tried Feedly? (feedly.com) I switched over to it ages ago after the death of google reader, and it's held up remarkably well for me, …

    When I first heard about this, I thought "oh man, how dumb! they're just going to make inflation worse!", and then I read more of the details. By my understanding, the case for sti…

    Could you clarify a little more about what you mean by this? Tomato skins are definitely hard to cut with a dull knife (without crushing the tomato flesh underneath), so many peopl…

    These ideas are mistaken. "Sharpness" is related to the physical size and radius of curvature of the apex of the blade, combined with the angle of the terminal bevel. [1][2][3] Chi…

    Can you share more details about how that hiring process tested for that? I'd love to hear about it.

    All right, I'll bite: https://www.usuallypragmatic.com I'm a physicist who's landed in the tech industry, so it's full of all sorts of miscellanea. Here's a few good places to star…

    Not really. Trees are actually somewhat hard to burn, so most wildfires start by catching dry underbrush on fire instead. So in this case, that would just be the alfalfa. Key to re…
