  • Hardware like that has been and is still being donated through third parties daily.

    It’s more in Ukraine’s interest to limit the use of Starlink to only those terminals that have been vetted through official channels than to allow blanket use and try to filter out things through other means due to… the exact kinds of situations this article is talking about.

    but that would require the CEO of the company to actually want to help honestly.

    Sure. And part of the reason we know Starlink is entirely capable of geofencing is because Elon’s done it explicitly to stop Ukraine from being able to operate near Crimea. That whole kerfuffle lead to military usage being pushed over to Starshield and a contract with the US government that gives them explicit say on when and where Starlink works in Ukraine.

    Elon is dumber than a bag of hammers but it’d be next level stupid even for him to willingly break a DOD contract, especially when people were already floating the idea of invoking the Defense Production Act last time around.



  • As long as you don’t need particularly tight tolerances or fine details, it works perfectly fine. The setup really isn’t anymore complicated than I described. I have done it just because I wanted to see how difficult the process is. It’s around $100 in startup costs assuming you have access to a printer. After that it’s mostly just waiting and occasionally measuring cut progress.

    Check out the Rack Robotics Powercore as well. It’s a low cost wire EDM system that uses cheap 3D printers as a motion platform. It uses a very similar principle to cut metal using wire as the cutting tool. May or may not be more suitable depending on your exact use case. Still pretty rough around the edges though; SendCutSend makes more sense for most people that need things cut from flat stock for the most part.



  • The reality is this is one of a handful of emerging technologies that are going to reshape a lot of things about the world in the future in ways I don’t think society, as a whole, is cogniscent of, let alone prepared for.

    This is one of them. The battlefield use of small drones is another.

    I tend to say that the world we’re living in now is one where gun control is increasingly obsolete. That’s not a moral judgment. It’s not a statement on whether that’s a good or bad thing. It’s just what I think we’re going to increasingly find to be the new reality: the rise of small scale, low cost, divertible manufacturing technologies is going to make traditional supply-side approaches to regulation untenable. That genie is out.

    (Drones are in a similar, if distinct space: low cost, commodity, and divertible from low/no regulation supply chains in a way that makes it nearly impossible to cut off supply without shutting down other legitimate economic activity).

    I don’t know what the right answer is. I do think it’s going to take a pretty fundamental rethink of how we approach these problems. I don’t think the full ramifications of these types of technology have really reached the wider zeitgeist, and, frankly, I kind of worry about how people will react. There are a lot of pretty scary paths this could take, both in terms of how the technology gets used and in terms of what attempts to curb them could look like if they’re not carefully thought through.


  • Machine is borderline overselling it.

    The ECM process works by pumping water containing an electrolyte through a metal part. When a current is applied to the water, exposed metal gets slowly etched away.

    What these groups are doing is starting with high pressure hydraulic pipe and inserting 3D printed jigs that are basically a negative mask to bore out the pipe to their desired diameter, cut the chamber, machine in rifling, etc, with the end product being a functional barrel. As far as I’m aware, so far this has been limited to pistol caliber cartridges; rifle calibers are a step up in pressure and come with a whole host of different engineering challenges.

    The “machine” is really nothing more than a bucket, an aquarium/pond pump, and a desktop power supply. It’s honestly a really clever approach to the problem from an engineering standpoint.




  • The BSG reboot really suffered from being a product of its era.

    It’s when shows were first really dipping their toes into telling an overarching narrative, but writer’s rooms were still very much geared toward producing stories of the week. The result was that a lot of shows at the time would start incredibly strongly, set up a lot of really interesting premises, and then just meander along because the writers were literally making things up along the way and because there was no coherent plan.

    Know how Game Of Thrones fell apart in the last couple of seasons when they outran the preplanned narrative of the books? That’s how a lot of TV ended up in the early 2000s. BSG and Lost are probably the two most prominent examples from around that time, but it was a pretty common problem as the format of TV shows was starting to change.


  • our last “just war” that was even a little cut and dry was world war two.

    The Balkans were pretty cut and dry in justified intent.

    It was an intervention into the worst genocide in Europe since WW2. We’re talking not only wholesale slaughter of civilians, but even the establishment of literal rape camps as part of an organized, systemic campaign of ethnic cleansing. What was happening in the former Yugoslavia was absolutely horrific and the US and NATO stepping in to put an end to it was an unequivocally good thing.

    That said, there were still questionable incidents like the “accidental” bombing of the Chinese embassy or the numerous cases of civilians killed by NATO bombs. But that mostly emphasizes the fact that there’s no such thing as a clean war. War is always going to leave blood on your hands, even if it’s being fought for the right reasons.


  • Canoo is supposedly going to make a pickup based on their electric van platform that looks really interesting:

    The expanding bed is an absolutely killer feature IMO. Small footprint the vast majority of the time but expands out large enough to fit a 4x8 sheet of plywood when you need that. All the fold-out workbenches are a really cool touch too.

    The whole thing feels like the Kei trucks people in other comments are mentioning but upsized and up-powered to be more feasible on US roads.





  • Part of what makes all the hatred for Common Core math so hilarious to me is that when I finally saw what they were teaching, it was a moment of “holy shit, this is exactly how I use and do math in real life.” It’s full of contextualizing with a focus on teaching mental shortcuts that allow you to quickly land on ballpark answers. I think it’s absolutely wonderful.

    But it’s so foreign to the rote manner that a lot of parents were taught that many of them have a hard time grasping it, and get angry as a result.


  • The article cites the opinion of an unnamed author of an unnamed “image encyclopedia.” Not really what I’d call definitive, which was the point.

    In my circles back then, soft G was predominant. I wouldn’t cite that as evidence of a One True Pronunciation either.

    There has always been debate about it. Hard G has certainly become predominant, but declaring that people that prefer soft G “weren’t on the internet back then” is revisionist at best.

    vi isn’t a text editor as much as it’s a text manipulation language.

    It has a syntax, grammar, idioms, and, yes, a learning curve.

    But once you learn it, it’s as close to a brain-computer interface as I’ve experienced. You start thinking about edits as chainable operations and it literally becomes muscle memory – if you ask someone experienced with vi how they just did a complex sequence of edits, chances are they’ll have to stop and consciously walk through it because they literally didn’t have to think about it the first time.
