your answer seems very specific on joules. Could you explain your calculations, since I cannot comprehend the mapping of how you would get a liter of gasoline to 16.8m tokens? e.g. does that assume 100% conversion to energy, not taking into account heat loss, transfer loss, etc?
(For example, simplistically there's 86400s/day, so you are saying that my desktop PC idles at 350/86.4=4W, which seems way off even for most laptops, which idle at 6-10W)
I'm pretty sure protobuf ignores new fields (if you add; assuming you add as an append, and not change the field ordering), and it recommends you not to remove a field to ensure backward compatibility.
There's pipework for circulating air inside it when they want to charge/discharge it, but yes, essentially it's mostly tons of sand.
They have resistors for charging it with electricity (resistors heat the air, air is circulated in the pipes which heats the sand) when the electricity price is cheap, and then for discharging they have a air-water heat exchanger so they can pump the heat energy into the district heating network.
Likely a combination of practicality, and the importance of airflow throughout the sand in order to heat it and pull from it effectively.
Also, water's specific heat capacity is 4.186 J/g°C, while air's is approximately 1.005 J/g°C. It would take much more energy to heat up water than it would to heat up air.
Also, water boils at 100 degrees, and they store it in the sand at 600 degrees.
You use electricity (ideally cheap solar/wind) to heat air. That hot air circulates through a silo full of sand. The sand holds the heat for months. Later the heat is drawn out and used for buildings or industrial processes.
I'm a member of the ACM, so I would report this article.
However, I think the author may just have made some mistakes and mixed up/-1'd their references, since the 2023 report is actually #2
2. Di Battista, A., Grayling, S., Hasselaar, E., Leopold, T., Li, R., Rayner, M. and Zahidi, S., 2023, November. Future of jobs report 2023. In World Economic Forum (pp. 978-2).
Similarly, Footnote 7 probably should probably point to #8
8. Nietzsche, F. and Hollingdale, R.J., 2020. Thus spoke zarathustra. In The Routledge Circus Studies Reader (pp. 461-466). Routledge.
I guess it doesn't help that the post is formatted as a typical article with the bio blurb. It's worth distinguishing the blog entries more and perhaps posting a disclaimer. After all when people think of CACM they don't generally have blogs in mind.
shooting a rifle is "easy" to learn. That's why long guns are used. Hold+brace, point, aim reticle/scope, squeeze.
handguns are harder, since you can't brace the stock against your shoulder, but need to learn how to brace with your wrists and arms.
anti-tank weapons a bit harder still, since you need to maneuver properly and have multiple shooters at the same target. Also, I laugh/smirk everytime I see a movie where someone uses a LAW indoors or in an enclosed space/with someone standing behind.
(I'm ignoring grenades; suffice to say it's not as easy to pull the pin with your teeth as you think)
I think the hard part isn't the shooting, but the tactical movement side; L shape ambush or fire formation when under fire, or presence of mind to seek to leapfrog or flank, ability to communicate under pressure instead of just hunkering down or screaming your head off. It gets complicated very fast since there are vastly different tactics used in forest/vegetation versus urban warfare, and choosing the wrong tactic will get you shot fast (think chess openings; choose the wrong one and unless you are an expert - which you will not be with 1 week of training, you will get mated fast).
Someone write a novel please. Not sure who will be more appropriate: Stross (more fun?), Stephenson (more of a slog through the first 600 pages, then an abrupt 180 and frenetic action in the last 100 with newly introduced, yet game-changing characters?).
> Stephenson (more of a slog through the first 600 pages, then an abrupt 180 and frenetic action in the last 100 with newly introduced, yet game-changing characters?).
With the six pages in the middle where he may as well say "Right, I had to learn a lot of algebra for compiler optimisation to make this bit work, so now you get to learn it too"
Agreed on the ridiculous page counts, but I don't find Stephenson's pages a slog. Exhausting, maybe. There's a lot going on. But he makes me laugh. I'd like to meet that guy.
It's not the greatest piece of fiction ever written, but Robert Evans of Behind the Bastards podcast has a pretty easy read[1]. It's also offered as a free audiobook read by him as a series of podcasts.
Might not be what you want if you want more technical & hacking versus dystopian capitalism collapse. But he gets bonus points for Texas getting nuked as a lore point.
