Why create an array each time it iterates a Set rather than just iterating the Set?

Yeah like npm! Don’t think there’s ever been security issues in that.

Matcha has caffeine in it though?

How big is the server runtime compared to v8 under the hood?

Yes, every one of those apps is c++ powered.

When text is (clearly) non native English I think most native readers don’t even register grammar errors.

To be honest most native readers wouldn’t register grammar errors full stop.

I guess I have more awe of people who speak a foreign language at all compared to piping it through some agent malarkey.

As the other posters have shown it’s not that hard.

Most graphics specs will explicitly say how tie break rules work.

The key is to work in fixed point (16.8 or even 16.4 if you’re feeling spicy). It’s not “trivial” but in general you write it and it’s done. It’s not something you have to go back to over and over for weird bugs.

Wide lines are a more fun case…

If you’re working in robotics and don’t have fully deterministic event based replay you need to find a new middleware.

Dynamic is still nice when you’re dealing with unknown data imo. More hygienic to read than dictionary access through string keys for example.

I use it when deserializing unknown message types.

You explain well so what I never understood is how the Jacobians aren't the first derivatives themselves?

Also if you have happen to have any suggestions for linear algebra for someone who uses it without really understanding it (I can write a measurement function for an EKF from scratch OK, but I don't really understand why the maths does what it does) I would really appreciate it.

Ah, I tried the gitlab and the tarballs 404 for me there, sorry I should have been more specific in the original post!

fwiw this does look interesting.

The download links for binaries 404 for me.

You can track debug symbol through c. It’s just one of many layers debug info gets tracked through.

Isn’t this because the wine db has those tweaks pre configured?

Are you?

The majority of production compilers use hand rolled parsers, ostensibly for better error reporting and panic synch.

You can source generate JSON serdes from your own source generator but you do need to generate the jsontypeinfo metadata yourself.
