scrotums not pussies! Pussies can take a pounding - a scrotum on the otherhand.....

Because national security is worth less than 25% of retail value!!

Whatever, dude.

Efficiency is based on differences in energy that are economically accessible, not on some rambling theories in a newline-free paragraph.

You can access room temperature. You can' economically access the blackness of outer space from the earth's surface. Likewise, you can access the negative terminal on your battery, but not some static charge in the upper atmosphere.

You pump X amount of energy into a heat engine, it expels that energy to an accessible exhaust, and typically 70 to 95 percent of that energy is *not* converted to work. You pump X amount of energy into a battery, it dumps that energy through a motor to its negative terminal, and only 5 to 10 percent of that energy is not converted to work. That's the only way to practically analyze the situation.

We could also all have infinite free energy if we could access the levels below the zero point energy in the quantum fields. One little problem: that's not accessible either.

Sometimes you can prove it was a bit flip [caused by cosmic ray, local radioactivity or a glitch in the Matrix], you just need to find the exact bit. A friend of that managed to do exactly that after an error in his monthly accounting software. He proved you could only get the resulting sum if you flipped bit Nth of a certain value during the summation. It took him a while and he had written the software himself.

I'll find out in mid January, lol - it's en route on the Ever Acme, with a transfer at Rotterdam. ;) But given our high local prices, it's the same cost to me of like 60kg of local filament, so so long as the odds of it being good are better than 1 in 8, I come out ahead, and I like those odds ;)

That said, I have no reason to think that it won't be. Yasin isn't a well known brand, but a lot of other brands (for example Hatchbox) often use white-label Yasin as their own. And everything I've seen about their op looks quite professional.

Ha, brings back identical memories of that time period. At one point the teacher was out of his field and I kept pointing out errors. He held the chalk to me and said un-sarcastically: "come here and finish the course for us"...

For the example in TFS of 200F water and assuming room temperature exhaust, Mr. Carnot says that the max possible efficiency is less than 20%. Any real world engine, including this one, probably ends up at a low-to-mid single digit percent efficiency. IOW, the vast majority of the heat would still be wasted.

The operator of the facility generating the waste heat might get more energy savings at lower cost by tweaking their processes to be a few percent more efficient in the first place, instead of trying to recover this low-grade energy source with an elaborate engine and plumbing.

Once you import numpy, Python has arrays.

That would never fly. You just know that some dufus at the gym would bring a 10kg steel dumbbell into the MRI room and ruin things for everyone.

I've seen Meta's glasses, and they look close enough to normal Ray Bans that you might not give them a second look. What was this guy doing to evoke such ire? I mean they look like normal eye glasses, not something unusual that would stand out like Google Glass.

They tried, but quarreling parent groups couldn't agree on whether to teach the kids that they were coding with 3 registers or 259 registers.

I think that many of those people were also recent DOS users. Given that DOS systems would often simply freeze up several times per day and require a reboot (easy to do since any bug in the user's application could do this), once they added a protected mode pseudo-kernel to Windows (maybe starting with Windows/386 2.1), it was actually a slight improvement over what they were used to since DOS crashes could sometimes be isolated to one virtual terminal.

Yeah, it's not even worth considering for something like 15-20kg. A full pallet in this case is 464kg :) Years worth of supply for me.

The current "AI" is a predictive engine.

And *you* are a predictive engine as well; prediction is where the error metric for learning comes from. (I removed the word "search" from both because neither work by "search". Neither you nor LLMs are databases)

It looks at something and analyzes what it thinks the result should be.

And that's not AI why?

AI is, and has always been, the field of tasks that are traditionally hard for computers but easy for humans. There is no question that these are a massive leap forward in AI, as it has always been defined.
