About ryandamm

I'm a camera/cinematography geek (among other geekeries). Working on holographic tech, which I've dabbled in dating back to 2009; it's been my full time vocation since 2015.

My personal email is ryan at impsf dot com.

    Curious if the authors are hanging around here and how they feel about the recent Leiden Statement. (Late in the article it’s clear that this is at least partially a publicity effo…

    Your comment prompted to look into this further, thank you. The funding situation in California is complicated and weird, but yes, CA does spend a lot of money on public education.…

    Well I live in a basic aid district; Bay Area but firmly middle class. We’re just above the cutoff for federally subsidized school lunches iirc, and the schools are chronically sho…

    This is interesting news to me, thank you. I'm curious if the per-pupil spending includes locally raised funds; the reality in California is that the state level funding is poor, a…

    The root cause of the collapse in math education in California is one bad researcher's work, combined with politics. Briefly, a Stanford-affiliated "researcher" named Jo Boaler pro…

    This already happens — my district when I was in school, and my son's district now, both have / had "alternative" high schools that kids get transferred to when they're struggling.…

    Did people really believe this was a financial behemoth? Or was this just a larger bet on the conglomerate that is Musk’s quasi-meme-stock empire?

    In his interview on the Hard Fork podcast, Palo Alto Networks’ CEO described the capability change from Opus to Mythos being more about availability; evidently it runs in a very co…

    In case anyone is wondering why this is important: the spherical harmonics are frequently most of the data in a Gaussian splat data set — as much as 80% of the data for good qualit…

    It's worth signing up for Levine's free newsletter and listening to the podcast (though there is substantial overlap in the content, it's still fun to hear what you've already read…

    Because it acquires an asset worth roughly that much, it’s neutral. GME is (probably!) not doing a huge at-the-market offering, they’re creating the shares and immediately giving t…

    This is not atypical; smaller company “buys” the larger company with debt on the larger company’s books. The blended shareholder mix is mostly the larger company; management comes …

    To be fair, that’s the recommended way to put out an alkali metal fire. At least according to my grandfather who helped write safety regulations for nuclear subs whose reactors wer…

    It would make it worse, by making the pectin available to be fermented!

    Missed in the previous discussion: methanol is irrelevant. Grain based ferments have essentially zero methanol.(And methanol risk is a function of its concentration relative to eth…

    This is called “ghost frame” and already exists in Red cameras and virtual production wall tools like Disguise.

    This is a good, succinct unpacking of the metaphysical stakes. Nonetheless I am curious for the world where striking a match results in a shower of seagulls.

    The article talks about how they are controlling for the variation across time, and they’re reporting a new signal. So even if everyone was working Saturdays before, everyone is mo…

    I suspect that the biggest limitation in printing vs. emissive displays is the simple fact that your contrast ratio and color reproduction is severely limited in printing, because …

    That’s precisely what LIGO measures, the gravitational waves from black hole mergers (or neutron star mergers, etc).

    Do you know that there is an actual voxel representation that exists before the self-driving AI? I was under the impression (from conversations with engineers who might know, admit…

    This is actually even more puzzling than it seems, because the green part of the spectrum is the most energetic. I've read elsewhere that photosynthesis is partially limited by dea…

    Genuine questions for AI engineers, or self driving car people: is the Tesla approach of only using cameras inherently flawed? I've read that the AI is directly hooked up to the ca…
