    One thing this overlooks is that the rigid mounted bed of the V2 causes thermal expansion issues. There’s a lot of really bad lore that gets repeated in the community re: bed heater power because the V2 tends to want to taco the bed if it’s heated too quickly.

    The WhoppingOrchard kinematic mounts are a solid option for addressing the issue.

    The Trident is the overall better design with a higher performance ceiling.

    Flying gantries are a solution forever in search of a problem. They can work okay and they’re fine at the speeds that were common when the V2 was first designed, but there’s a reason why the community has converged on fixed gantry designs. They’re neat to watch operate but they don’t offer any practical advantage. The V2 tends to be relatively slow by modern standards, especially in terms of accel.

    The Trident isn’t without flaws but it’s a perfectly fine starting point and the huge community does mean that most of the bigger design issues either already have a usermod or somebody working on cooking something up.


  • 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.






  • The HA SkyConnect does Zigbee and will eventually add Matter support. Z-wave needs a separate dongle, though.

    I’ve literally been in the process of migrating all my Home Automation from SmartThings to HA over the past couple of weeks. I have a mix of Zigbee, Z-wave, and WiFi devices. The HA side has honestly been easier to set up than SmartThings was in the first place.

    I’ve also been working on getting some cameras set up with Frigate and Coral object recognition. That part has been more involved, but I’m pretty happy with the functionality so far.

    I’ve definitely been happy with my decision years ago to stick to devices using standard local protocols. Has made the whole process far less painful than it could have been.

    Funny enough, one of the few things I have that uses a proprietary hub/app are my Hue bulbs – they were my first dip into home automation a decade ago. I haven’t ditched the Hue hub quite yet, but moves like this definitely make me more inclined to.
