    Honesty I know a bunch of people who are burntout climbers and burntout geologists - sounds like a blast. Fun mineralogy with climbing that’s not…super exotic but still fun? I’d pa…

    No, good thermal management with a chiller, active thermal compensation, and glass scales make um precision on that scale reasonable. 10-100x better? Sure, you’re getting into mach…

    Ok but my neighborhood children have started using electric leaf blowers as jet propulsion on skateboards. I have insisted they use hearing protection, but the rest of us are shit …

    It’s fun seeing an uptick of rhino/grasshopper content here lately - two articles in a week?! The McNeel extended universe is a fun place to play around in, and I’ve met lots of gr…

    You've got the heat cycles for annealing, hardening, and tempering confused. The slow cooling is for annealing, hardening requires a fast cool from rather hot and is a very differe…

    It doesn't really detect stringing together latinate nonsense, so all of my coinages got perfectly coherent definitions. On the flip side, I guess if you're erudite and willing to …

    Very important habitat restoration for electric eels, actually.

    I'm not running the show, but I am working at a place that does this. One time fee for a perpetual license for the current major version, free support, and historically ~6 years of…

    Turns out you can take out a driver side mirror by putting most of your weight on it and bouncing a few times. But that's reserved for drivers that have made contact with me...

    If we're "unbundling"/giving into "free market" nonsense in a highly regulated area, I just want to be able to pay reasonably proportional fee for musical instruments and get a gua…

    This is a real worry? Don't you just not go to meetings but otherwise solemnly swear that you're working on the plane?

    Machine shops actually used whale oil until quite late. Much better than equivalent petroleum products until the '50s or later.

    I was using it to build a dilatometer - an instrument for measuring thermal expansion curves of materials. Theoretically simple, in that you take a sample of something and measure …

    LVDTs are fun! I bought one for a project a few years ago (since abandoned), and have been slowly designing my own readout electronics for them. Three revisions later, and the perf…

    As a consequence of the aging members, a lot of churches (particularly the less virulent mainstream protestant flavor) around here are merging congregations and getting demolished,…

    That was a line directly from The Hitchhiker's Guide to the Galaxy.

    That's exactly a disposable camera flash circuit.

    Don't worry, if you don't know what BIM is, you don't need BIM and you should be thankful about your previous life choices. Weirdly, no one in BIM really seems to agree on what BIM…

    "Droplet superpropulsion in an energetically constrained insect"( https://www.nature.com/articles/s41467-023-36376-5 ) is a great paper from the same authors - I came across it las…

    I second this; this is super bad advice. CO2 systems are comparatively safe from an eye damage perspective - unless you take a direct hit, (...don't, seriously, that's what interlo…

    I don't know about that. Paying yourself a nice salary, having a stable job doing something you probably (at least at one point) find interesting, and having lots of autonomy seems…

    Yeah, but that lineage of banjos became 17-fret tenor banjos in the teens, which are still really nice instruments if you play Irish trad tenor and don't need the volume of a 23-fr…

    Well, there isn't a meaningful inner product, so how can you speak of parallelograms? The geometries are definitely weird! Once you leave p=2 and break the rotational symmetry arou…

    One thing this doesn't touch on is that there are multiple meaningful definitions of pi-like constants for the p-norm unit circle that don't necessarily agree with each other in p …

    CT is the wrong imaging tech for Moka pots at least - they're much cooler looking if you're doing neutron imaging and can see the water: https://www.youtube.com/watch?v=VESMU7JfVHU…
