Since it's so germane, I'll share my little widget that compares EU countries to US states on various metrics: https://evmar.github.io/states/
Does Czechia really have 4 million square miles and NaN population?

I'd suppose this really depends on how you are developing your codebase but most code should probably be using a trailing return type or using an auto (or template) return type with a concept/requires constraint on the return type.
For any seriously templated or metaprogrammed code nowadays a concept/requires is going to make it a lot more obvious what your code is actually doing and give you actually useful errors in the event someone is misusing your code.
I don't understand why anyone would use auto and a trailing return type for their functions. The syntax is annoying and breaks too much precedent.

I'm pretty sure the issue was with 'move fast and break things' and not using carbon fiber.
I think it was on the youtubes I was watching a story about how they built that thing and it was <spoiler alert> not really fit for purpose. I mean, no big surprise in hindsight.
Carbon fibre has poor compressive strength and good tensile strength.
That makes it inherently bad at holding pressure from outside in a submarine and good at holding pressure inside a spaceship or airplane.

The problem is how do you set up those permissions without a god object? How do you fix ones that are broken on a running system?
Ultimately the security systems that introduce high complexity in the name of fine grain permission controls end up being the most fragile and hardest to verify. People get stuff wrong then break it further trying to get their job done. The better system is sometimes the one that doesn’t have all of the features but is comprehensible to humans.
Selinux and AppArmor?
Android has it figured out too.
Something that occured to me years ago is we have a quirk in English language that gets in the way of accurately emapthizing with each other, especially when trying to design things well (like products and experiences). We don't say "unwant", and we don't clearly differentiate between a lack of want and a repulsion or unwant or negative want.
Someone might say "I don't want x" or "I don't need x" and it's unclear if:
- they see no value in x
- they see small enough value in x that they don't care
- they see negative value
So much time and energy is wasted on misunderstandings that stem from this ambiguity.
It ruins products, is loses deals, it screws up projections, it confuses executives, etc.
It gets in the way of accurately empathizing with and understanding each other.
Because "I unwant x" means something extremely different than "I don't want x". Unwant implies some other value that x is getting in the way of. Understanding other peoples' values is what enables accurate empathy for them. Accurately empathizing with customers is what enables great products and predictable sales.
"I don't care about x" clearly indicates a lack of want but is considered ruder than "I don't want x".

> If a machine can do this assignment perfectly, why are you giving it to this student?
By that logic now that text to speech has gotten quite good we should stop teaching kids to read.
Many of my university classmates would give up on more than one paragraph so I'd say we're already there.

Tangent: is anyone using a 7900 XTX for local inference/diffusion? I finally installed Linux on my gaming pc, and about 95% of the time it is just sitting off collecting dust. I would love to put this card to work in some capacity.
I've been using it for a few years on Gentoo. There were challenges with Python 2 years ago, but over the past year it's stabilized and I can even do img2video which is the most difficult local inference task so far.
Performance-wise, the 7900 xtx is still the most cost effective way of getting 24 gigabytes that isn't a sketchy VRAM mod. And VRAM is the main performance barrier since any LLM is going to barely fit in memory.
Highly suggest checking out TheRock. There's been a big rearchitecting of ROCm to improve the UX/quality.

Unless it’s there to conform to an interface
Especially if it's there to conform to an interface. You can comment out the variable name and leave the type.
