Training a model is more like taking an alien (from a different universe) and teaching it a huge chunk of the entire human civilization. A better comparison would be how much energy it takes for a human to produce a page a text (roughly the equivalent of 1hour of thinking?), and how much energy it takes for an LLM. GPT Sol estimates a frontier LLM is 10-50x times more efficient than a human at generating a page of text.

to my knowledge, the cost of uranium is almost negligible compared to the capital cost of building the plant. so as long as a market exists, you can choose whatever strategy: buy a big buffer, or just don't care if price oscillates x times.

does synergy works better now? 3 years ago, every week I would get into a situations where one machine was not connecting to the other, and I had to randomly restart synergy so maybe it connects. fun to do that 5 min before the meetings.

I suspect that you can modulate nuclear power too, but why do it? after you started the reactor it runs practically for free? (the fuel cost is so small; or it costs the same to run full power of half power). disclaimer: I did not read actual details about nuclear power plants designs in the past 20 years, so i'm vibing from first principles and bad memory

I agree, we try to think in terms in state machine. Just complaining that somehow this is not good enough, in practice we need to add random flags, and it is not clear how to separate the multitude of separate state machines all active at the same time.

"No statechart will survive contact with real world applications". I mean, when you have external dependencies, multilayer protocols, multithreading, perf requirements, the state will becomes an ugly mess. One can only dream of a clean statechart.

How does GPS work? 3 months ago

(also you receive the signal from all satellites at the same time, on the same freq, and some random reflections. and then you need to extract independent streams of bits for each satellite, each with its own nanosecond timestamp for receive time)

How does GPS work? 3 months ago

And then you try to actually build a GPS network, and ask yourself: what kind of antennas should we use? what should be the freq? how much power? how will the receiver detect the precise nanosecond when it receives an incredible weak signal? (in current GPS the signal is bellow thermal noise)

You could use colors in the step-by-step simulation to show dependencies. Also show some tooltips/comments when things happen (that you described above). Ideally one should press next next next in the simulation, and understand what happens better than the paragraph description above.

The Physics of GPS 3 months ago

I found much more interesting the way the gps electronics work. What do you mean you need to know the exact moment you receive a message from a satellite with nanosecond precision? when the message itself is several seconds long.

A long time ago (pre-internet) I heard a normal person can learn to juggle in 1 day. It took me 2 days, but I learned to juggle 3 balls. But soon I realized what you said, the need for a consistent toss. Not sure of the reason, but I always make some errors with physical movements, they are never perfect. Even with typing, no matter how much I exercise, I cannot get bellow ~3% errors. Wondering if this is some kind of genetic effect, and how many ppl have similar issues.
