  • Prusa was all in on open source for over a decade. All their machines up through the MK3S+ are GPL hardware, firmware and software. What did that get them as a company? A lot of people selling near identical copies of their hardware for lower prices. Prusa’s leaning away from open source hardware because it pretty much meant doing their competitors’ R&D for them. Hell, Bambu Labs relies on code developed at Prusa Research. So their ecosystem is closing up somewhat.

    You are right, a big strength of Prusa’s is their mod ecosystem, their community. They are well aware of this, which is why they’ve come out with their OCL license. The Core One isn’t GPL, it’s OCL, source-available. It’s illegal for anyone to start making blatant copies, but the CAD files are there for reference when making mods and accessories.

    Prusa’s MMU3 is in several ways superior to Bambu’s AMS: you get 5 spools, not 4. Retract-based tool changes are faster than purge-based ones. Retract-based tool changes are less wasteful than purge-based ones; Prusas don’t poop. And yet, Bambu finished the AMS, Prusa merely got the MMU3 working. Installing an MMU3 requires a fairly invasive modification to the Nextruder and a desk full of tubes and nonsense. I think Prusa’s going to catch up there with the INDX system with the MMU3 as basically a legacy product.

    The market for “kinda polished, easy DIY 3d printing” is small and shrinking. I know because I’m in it, and us kit builders are small potatoes to them. Prusa is trying to position themselves in the professional and industrial sector; they’re releasing a “Pro” line of turnkey print farm and industrial solutions, they sell tungsten fill radiation shield filament and certified encrypted USB drives. I believe they are working on a self-hostable version of PrusaConnect, likely aimed at their higher end customers who are more likely to balk at using anyone’s cloud service. To that market, “We’re not Chinese” is Prusa’s biggest selling point.















  • I will assert that, again, for most people, instead of computers remaining at the same TDP but increasing vastly in processing power, they would have been fine with the same processing power at vastly decreased TDP. Look at how long people held onto Win 7, and how long they held onto Win XP before that. Because they were fine, possibly better than the new offering, especially since you already owned it. Some time around 2012, anyone who wasn’t a power user ran out of reasons to get excited for new computers.



  • In some part because weather isn’t the same in all English speaking countries.

    A lot of the world doesn’t get a significant amount of what Americans call “sleet”, it’s either mixed in with, or the brief transition between, rain and snow. The quirk of having the huge landmass of Canada up in the North, the warm waters of the Gulf of Mexico to the South, and no East-West mountains to keep them separated means we get huge masses of moist warm tropical air lifted high above dense cold yet dry polar air, that tropical moisture condenses and falls through that polar air and has enough time to freeze on the way down, completely and continuously for long periods of time.

    Subjectively, sleet is snow’s dipshit loser brother. Snowfall is silent, in fact it’s silencing, it’s like it sucks the sound out of the world. Sleet hisses like rain on fast forward, it’s almost like pink noise. Sleet is denser than snow; an inch of sleet is more precipitation than an inch of snow; it has less surface area so it’s harder to melt and it’s heavier, so it’s harder to move.

    Not to be confused with hail, which is frozen precipitation that occurs paradoxically in the summer in vicinity of severe thunderstorms. Convective activity catches precipitation and throws it very high into the atmosphere where the temperatures are cold, so it freezes. This happens over and over again until it is either too large to be lifted again or it gets thrown clear and lands some distance from the storm. The major threat from hail is impact damage.
