I agree, you can use an old desktop, laptop, or if you don’t have something I had good luck with the local university surplus store.

You could just hop back through time doing this, and no one could ever catch you at the end because you hadn’t even committed those crimes yet

The Chinese market already has better EVs than Tesla for cheaper afaik. Teslas don’t sell well there anymore.

If you’ve seen that blue-ness in the sky you’ve seen air.

Just scoot forwards a bit?

That’s interesting, I can see both circles but my hand does always go to my right eye unless I force myself to look at the other. That makes sense I guess because my right eye is more focused at a distance. I wonder if that switches though when I look at something close up for a while, because my left eye is more focused then.

I’m kind of weird I think in that I can focus further away than something I’m looking at, but I can’t focus closer than something I’m looking at. At the same time though I can cross my eyes to converge closer, but can’t push them apart to converge further away.

It dissolves in water, so you can also just let things soak for a while. Glue stick is made of the same polymer that people use to print dissolvable support material.

Glue stick washes off in about 30 seconds. I wouldn’t want to use it all the time, but for just 1 part it won’t inconvenience you very much.

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

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

don’t worry about performance, GHz will always go up

TF2 devs lol
