How's this for an example webpage? https://www.usuallypragmatic.com/ember/ It has live examples in coding / data visualization / image display / animation &#x…

Fair point on the naming collision. I know these sorts of color filters end up with different names via different apps on different platforms, so just describing it as 'redshift safe' seemed…

That's a... surprisingly deep question. I'm actually a physicist by background first, so I got my start doing waaayyy too many calculations with blackbody and emissions spectra. Then, back i…

Added in a Table of Contents at the top to improve it for now. May do more substantial re-writes later.

Really glad you liked it! I use an absurd amount of redshift personally, and have spent too much time thinking about / working on light-and-color related projects, so it came out of a place of ne…

Can I ask which parts? I wrote the intro section by hand, and left the rest of it Fable-generated with significant "guidance" and rounds of re-writing. I think the current weakest part is th…

Example web pages is a great idea. It's a very new project (just did it over a couple of evenings during a trip last week), so there's nothing formal out there yet, but I'll add in some…

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 is the stra…

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 of your mental and ph…

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 enough that we&#x…

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, meaning. This r…

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, was just pla…

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 be…

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: 2.95…

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 did some googl…

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 by things like hip …

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 Banta…

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 you measure…

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 math academy has not on…

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 to "turn …

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, and now also in…

Ignore all the other answers and skip straight to this one. Math Academy is amazing. It's got everything you could want (mastery based learning, knowledge graph dependencies, assessment tests, a …

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 stimulus…

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 people will default to us…

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] Chipping of a…

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 go…
