Progenitor of the Weird Knife Wednesday feature column. Is “column” the right word? Anyway, apparently I also coined the Very Specific Object nomenclature now sporadically used in the 3D printing community. Yeah, that was me. This must be how Cory Doctorow feels all the time these days.

  • Well, two things about that.

    One, the L1 Lagrange point between the Earth and Sun is further out than the orbit of the moon. Even without doing any math, just a cursory observation of how shadows work will illustrate that, given that the moon itself can just barely cover the disc of the sun from where it is, any such object placed there would need to have a diameter larger than that of the moon in order to completely block the sun’s light. Or some appreciable and nontrivial fraction of the diameter of the moon if you only want to block part of the sun’s light. Lofting something that massive up there and more importantly keeping it there given that it’d also be well within the gravitational influence of the moon would be quite the challenge. (“Quite the challenge,” by the way, is rocket scientist talk for, “This is complete science fiction, and whoever suggested it is insane.”)

    Point two is that the Deep Space Climate Observatory is currently already parked there.






  • Likewise, back when I built my first big pants real PC out of actual new components and not just hand-me-down bullshit cannibalized from decommissioned office stuff, I put the plethora of stickers that came with everything on the little rear triangle windows on my car. As if they were riceboy components instead, which in a way I suppose they were. Many of them were those textured stamped aluminum ones and they survived for quite a long time.

    Surely at least one confused tuner saw this and puzzled over what the hell G.Skill and MSI “car parts” were supposed to do.

    Here’s another sign of the times: Out of all the parts for my current rig, only two of them came with stickers. What a rip-off. My processor came with an AMD sticker (just a cheap vinyl one this time) and my motherboard came with an Aorus sticker which is at least textured metal. I stuck both of them to the inside of the front door on my case.


  • Not to be a stereotypically insufferable Stallman style neckbeard about it, but the only two objectively correct answers to this question are FreeCAD for mechanical parametric things, and Blender for organic shapes or decorative models. (You can also bully Blender into doing parametric CAD work with plugins. And I guess OpenSCAD also counts, if you would rather program your models rather than model your models.)

    All of the other available commercial options are some combination of:

    • Proprietary vendor lock-in bullshit
    • Subscription model “software as a service” perpetual money sinks
    • Always online cloud services that either steal your models/make them available to anyone/probably also report you to the Feds
    • Loaded with quasi-legal licensing restrictions that prevent you from distributing or selling your own creations made with it

    Or for extra bonus points, all of the above!

    FreeCAD isn’t exactly slick and it has a rather precipitous learning curve, but it’s also basically the only viable truly free option that won’t spy on you, steal your stuff, or turn you upside down and shake you for money on a monthly basis.




  • Late in my high school career I got accosted by some dillweed in an empty hallway. I have no idea what his beef was, but what with my lifelong predilection for being an insufferable snarky asshole it’s not tough to imagine pretty much anybody could potentially have a bee in their bonnet over something I said to them at some point, once they had a couple of days to ruminate over it and maybe look up some of the longer words. And for all anyone knew I was just some scrawny nerd who did calligraphy and played stupid card games. Easy pickings.

    Anyway, this punk comes stampeding up to me while popping off at the mouth over how he’s going to whoop my ass and I’m a bitch and this and that and the other thing. I figure I know what he’s going to do. He’s either going to do that braindead bully maneuver where he tries to crowd your personal space with his face 2" in front of yours while yelling and flapping his arms around behind and to the sides like a hysterial chicken, in which case I’m going to kick him smartly in the balls. That, or he’s going to try to tackle me.

    He tries to tackle me.

    Since I saw this coming from a mile away I cut him off by grabbing him by the throat with one hand, roughly the belt with the other, used his own momentum to hoist him up onto one shoulder, and I swear upon my oath that I did a Shinkuu Nage on this motherfucker right over my head and threw him flat on his back onto the tile floor.

    Pose at the end and everything. I couldn’t resist. No one witnessed this except him and me. I wish I had it on video. And that was the end of that. Curiously, after this it seems he had suddenly run out of things to say. He elected not to get up. I left him there and walked away.

    I did a lot of unwisely flamboyant kung-fu shit on people in my younger years, often to only middling success. But this was perfect, and I will probably never pull it off again so long as I live.



  • My closest brush with celebrity was being peripherally involved in the skating scene back in the day and in the same town as Bam Margera, when he was just starting to get famous. Bam is, was, and probably always will be 5’4" worth of complete flaming douchenozzle. It’s no surprise that everyone had a story about how that one time they almost kicked Bam Margera’s ass. Or actually did fight him. I imagine this would have gotten significantly more difficult over time as his entourage of groupies and sycophants grew ever larger. Eventually he stopped making local appearances altogether. I’m sure as he tells it that’s because he was now so famous that everyone else was clearly beneath him and he was now untouchable, but I imagine the real reason was much more pragmatic: it was probably only a matter of time before somebody finally put a hole in him, and he knew it.

    So yeah. This one time at a skate park in the Philly suburbs, I came this close to beating Bam Margera’s ass. I would have won, too, if it stayed mano-a-mano. But it wouldn’t have, because he’s a little punk.
