  • Hello fellow CAD friend!

    I don’t know exactly which program you’re using, but a lot of the ones which are Linux-unfriendly sadly won’t even work on a VM. You will have to have an entire dual boot configuration for them. The good news is that if you’re still on a tight budget, decent 7200 RPM, 1TB hard drives can be had for around $40, sometimes less.

    Minecraft is a whole different beast, and honestly it’s harder on my system than some CAD work… but can still be managed.



  • Be fair and equitable. There are times when strictness benefits a community, and there are times where laissez fair, laid-back moderation benefits a community. But nothing hollows out a community like moderators being unreliable or unfair.

    If you’ve got a “don’t be a dick” rule and someone is making a point you agree with but being a dick about it, you still have to step in. If you’re having a bad evening, don’t let yourself be extra hard on people because you’re angry or rushed. Etc.


  • Not Republican myself, but work with a lot of them. I’m seeing a few different camps right now. I can’t really speak for exactly how many fall into each, but can only give estimates based on my subjective experiences:

    • The “Leopard-Facers”: The ones who’ve suddenly woken up to the fact they elected a moron and a bully. These tend to be foreign policy hawks, and may have only voted for Trump reluctantly. Probably the smallest group.

    • The pure Trumpists: A mix of people who thought the US should be isolationist anyhow, just don’t like Zelensky in particular, or just are too invested in the vision of messiah-Trump. Obviously they’re thrilled. Very vocal, but I think also somewhat fewer. Maybe I just hope they’re fewer.

    • The cognitive dissonancers: Probably the greatest number. There’s a lot of different views under this umbrella. Some of them were buying into the idea “he’s just blustering for a better deal”; some thought the message was on-point but the display was inappropriate; some actually support Ukraine but can’t bring themselves express any actual opposition to this shitshow. Broadly speaking, they’re all squirming - struggling to reconcile the appeal they feel for his persona or other actions he’s taken, with their opposition to his foreign policy and this in particular. Yet not able to accept reality like the Leopard-Facers.









  • Yeah, I do apologize - I’m somewhat simplifying my explanation because when you start going into the full detail, it just brings up more questions.

    So yes, like the other comment says, the particles are constantly bouncing into other things.

    • If they’re bounded in by something - walls of a container, or even just more gas surrounding the specific sample you’re looking at - they’ll bump into that, and transfer some of their energy to that.
    • If they don’t have something to bump off of and the particles are free-floating, they’ll take off in any given direction. If they only have something to bump off of in a limited number of directions, they’ll take off in the other direction. (For instance, in a rocket engine, we make a lot of molecules really, really hot and then surround them with barriers in every direction except the one we want them to zoom out in.)
    • In some cases, the molecules have electromagnetic bonds with each other, which take more energy to break than the energy contained in their “bouncing around”. So they’ll stay stuck, just bouncing off each other, even in a vacuum, (Or at least, until they radiate away their heat via electromagnetic energy… another whole story.)

  • Yes, and no. Heat and kinetic energy are fundamentally all just energy. What we call heat is, technically, the kinetic energy of molecules vibrating around.

    When exhaust gas passes through a turbocharger, it is both slowed and reduced in pressure, resulting in it coming out slightly cooler than when it entered. This device is using a different method of getting energy out of the exhaust gas, but it’s fundamentally still the kinetic energy of those very energetic exhaust gas molecules bouncing against one side of the thermoelectric generator and giving up their energy into it. I would still expect the exhaust gas to come out of it slightly cooler and slower.
