Now which one is safer? A new Postgres written in Rust, or the original real world tested Postgres?

Oh yes the mute button, very useful when trying to pause a podcast :(

Even for PC, I recommend some cheap studio monitors.

Well, we are dumb and we make stupid mistakes, and code review can find and fix them sometimes. I am very surprised that the practice of "review" is not more widespread. For example when I see medical doctors going YOLO with their patients, ppl driving excavators, etc.

How much of this work is "with 5 parameters I can fit an elephant"?

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.

search the micronised version, it is so fine it looks like it disolves completely.

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.

This is strange to me, with quartenions you model rotations in 3d space, not 4 dim rotations.

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

Europe was spending 200 billions / year on gas from russia. I imagine they could try to build 100 reactors for that price, but it would take a couple of years I imagine...

So sad we could not apply economy of scale for nuclear... The main reason solar and batteries are so cheap is economy of scale.

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.

But I see all the "QR codes" have a hexagonal symmetry? So basically you can use only one corner (1/6) to represent a node? Why do they keep the entire hexagon?

(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)

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)

The hw implementation of xor is simpler than sub, so it should consume slightly less energy. Wondering how much energy was saved in the whole world by using xor instead of sub.
