I started mirroring as much of the core git repos I depend on to my NAS with systemd timers to update from remote, and post-receive hooks to mirror externally if I control the repo. This reminds me that I should expand those efforts

No instrument gives you an infinite precision in which to encode information with or decode it back out (though in quantum systems the result quantizes to one of N possible states depending on the system, so this is moot). The other option is an infinite amount of time to continuously encode information, but practically decoherence becomes the limiting factor.

I don't have a formal education in QP so this comes from my engineering perspective of working on quantum computers.

I just... don't agree. Every pitch in baseball is exciting and there are almost 300 thrown in an average game, even if most end up with no progress. Meanwhile I find "fragile equilibrium" games to be boring as hell to watch, there's hardly any progress being made! I don't want to watch an abstracted tug of war drawn out over 3 hours.

It depends on if you have parens for (explicit) modules like some Lisps do.

I find this to be completely the opposite of my recent experience. The games are fast and with much better, consistent payoff than other sports such as football and soccer. Progress is far more discrete and there's basically always something happening except during inning or player changes. I agree that there are a lot of games, but that's a feature: you don't have to pay attention to every game. Because of the discrete nature of progress and the number of games you can get meaningful statistics out of a single season. I say this as a relatively young person (<30) who only loosely follows other sports.

I just started getting into baseball this year because of the Brewers stellar performance (I'm from Madison).

That has to be a nightmare for parsers lol

> Rust will never replace C/C++ with regard to high performance computing.

I don't buy this. Rust is a lot easier to make more performant than C++ and doesn't really trail behind C in anything but .text size last time I looked. Considering you can easily write C-like Rust that ends up in the same LLVM stack as Clang (more or less) I just don't think this is true outside of some very specific contexts.

Maybe you can theoretically encode arbitrary (but not infinite) information, but there are still discrete underlying states.

Formula 1 cars also have massive amounts of heavily engineered downforce and negative camber to give them insane amounts of grip. Pretty much every street car has enough braking power to lock its brakes in almost every condition but doesn’t have nearly the grip to utilize it.

Bigger brakes != more stopping power.

Too bad this didn't make it into the new Kindle Colorsoft. Oh well

> Once the models are good enough

That's a big "if".

Even for coding these things are not ready to take away real decision making and it's not clear they will ever get there.

I've worked with neutral atom QCs before (though am not a laser tech): keeping lasers locked is a massive pain in the ass.

> more so effort should be spent on making the technology cheaper and more accessible

Lasers are weird because the techniques to generate light at different frequencies differs a lot. "Telecom wavelengths" used in, say fiber optic networking, is super cheap and widely available, but these QCs often need different wavelengths that aren't mass produced. Some systems even need the ability to tune the wavelength precisely and the range of that tuning is another spec that can matter. I'm sure these QC companies would love for this to be more stable and cheaper, but the reality is without demand (of which there is little), it's just not going to happen.

Pretty much any bluetooth headphones work connected directly to the AppleTV, not just Airpods

For tech especially I don't think that's necessarily true.
