> Circles and the relationship between their circumference and diameter existed before minds existed There really aren't any circles in the physical universe. There aren't any ellipses either. I'm not sure about lines.

Are these the bonds where you can only buy $10k to $15k per year? If so, that doesn't solve the problem for anyone who has the problem.

What is the Proton mail affair? Recently I was thinking about creating an account with them, so I'm interested.

> I just assume they have the goal of killing the language Sadly, that's my conclusion too. I really wish there was a good "portable assembly language", and maybe that'll be something that targets WASM.

Yes, I can have functions/methods that do math differently from the default. I could just as easily say that's C's way and mix and match those: int64_t x = add_i64_with_abort_on_debug_and_wrap_on_release(y, z); uin

Don't kid yourself about "superior" - only Wayland developers and fanboys care about the simplicity or cleanliness of Wayland's implementation. Wayland's killer feature for an app developer is "vertical sync&q

I agree with your point, but note that Rust does have an ugly way to do it: https://doc.rust-lang.org/std/primitive.i64.html#method.wrap... I'd rather just put `-fwrapv` on the command line that clutter my code wi

Yes, so fix the C standard... But the compiler guys won't let the anyone fix it, because optimizations. So either A) the optimizations using UB are important, and therefore C is/will-always-be faster than Rust which doesn't

No, what's astonishing is that now that every CPU worth using has 2's complement for signed integers, the compiler writers are still embracing undefined behavior in the name of piddly optimizations. I was tempted to specify "

This is more like Python 2 vs Python 3... Wayland will win because "new is better" to the mob. After it takes over, it'll be worse performance for 4-5 major releases, and you'll never get back all the features. All the

There are plenty of examples throughout history where an inferior product won out over the alternatives, usually because of business or politics unrelated to merit.

It seems to me there's some uncharted territory between "massively parallel" (GPU) and "unpredictable branching" (CPU), and the corpse of Itanium is laying there as a warning to anyone who would go exploring in that

Lol, when C does it, it's "unsafe". When Rust does it, it's "modular"!

Any of those instructions could be wrapped in a C function or intrinsic if they were valuable enough

I understand your point: Modern hardware tries REALLY hard to pretend it is a simple set of instructions executing one after another. For all the on the fly clever caching, micro-op translation, branch prediction, speculative execution, r

I would rather die than lose all my retirement savings and be forced to find a job in my 60s or 70s. No hyperbole at all.

I would pay thousands of dollars for this, literally. I'm currently paying many thousands of dollars for fairly mediocre real life human teachers who barely try to understand my question before they repeat what they already said. Chat

What does a try expression like this do? Returns null/undefined on a throw? I suspect you could do something like: const c = attempt(() => ... ); where attempt invokes the lambda, catches any exceptions, and does what you

Calling bonds a bad gamble is questionable. The Fed rate goes up, the price of bonds at the old rate goes down, a minor bank run forces them to sell the bonds at a loss to cover the withdrawals. Were they supposed to invest in stocks, opti

I'd give them more credit for digging us out of the hole, but I think having the Fed rate near 0% for so long created most of problems in the first place. That started well before the current or previous administration. (I know we&#x2

The original author was talking about hardware not behaving like linear memory, and other than caches and maybe some thread local tricks, I'm not sure what he meant. However, it seems pretty clear that CPUs do try really hard to make:
