If you plan on plugging in a monitor and keyboard and using it as a more general computer it's a lot easier to justify

I think it's fine to have some less commonly used actions be only accessible through a terminal, even on more user-friendly distros. That is basically what Minecraft does, and yet no one's scared of that.

The ti-84 plus is based on the zilog z80. From 1976. The calculator is still being made, and still costs $100.

Better calculators just use floating point math with a few tricks on top to pretend it isn't floating point math.

I was thinking about this a bit yesterday and I think the most feasible way would be to suspend a glass sheet above the lake, and then give people harnesses with magnets on the top that attach to magnets on the other side of the glass sheet. Then just put ball bearings on both sides to reduce friction.

You could try to use magnetism or something tho, although that means you'd only be able to walk on specially prepared lakes

Unless there's force coming from somewhere other than buoyancy, you can't get better than than 1.29 kg per cubic meter of lift in air at stp.

Well, air weighs a little bit more than 1 kilogram per cubic meter, and those balloons look a little bit smaller than a cubic meter

[–] AdrianTheFrog@lemmy.world 2 points 1 week ago (9 children)

The theoretical best lift from a balloon that size is about 1 kg I would estimate

Well, if we used a pure vacuum, you'd only get about 17% more efficiency than just using helium I think

Any amount of water contact introduces a fair amount of drag. There may be an ideal point somewhere in the middle, but I think if you take this to it's natural conclusion you get a zeppelin.

I did a little bit of math and I think that to lift the payload capacity (including fuel and crew) of a modern day Panama canal ship you would need about a tenth of the peak U.S. helium reserve (a cube about half a kilometer long on each edge, about 1.3x longer than the long dimension of the ship)

I don't think you'd get the best fuel efficiency going upwind lol

Anything smaller would come with proportionally less downsides and at least proportionally less benefits. I doubt it could ever be a net positive in any useful metric.

There's also fedora kde

 

With the smaller 14b model (q4_k_m), just letting it complete the text starting with "why do I"

edit: bonus, completely nonsensical (?) starting with "I don't" (what could possibly be causing it to say this?)
