Seconded - those RealTek dongles are no good. For my Macs, the IOCrest USB4 adapters with the AQC113 chipset have been rock-solid and can saturate my 10Gbe network. They do run hot but no stability issues. That's what I use and recomme

I bought one of these as soon as I heard about it ($74 from eBay) and tested it against my USB-4 AQC113 mainstays ($87, IO CREST brand on Amazon), from my MBP. The new RTL-based adapter is physically smaller, runs way cooler, but only gets

This paper missed the state of the art!!! This concerns unsigned division by a 32 bit constant divisor. Compilers routinely optimize this to a high-multiply by a "magic number" but this number may be up to 33 bits (worst-case, div

I was curious how defer is implemented. `defer` in Go is famously function-scoped, not lexically-scoped. This means that the number of actively-deferred statements is unbounded, which implies heap allocation. The answer is that Solod breaks

Thank you for flagging this, that definitely shouldn't be happening. Possibly we have an over-zealous spam filter. If you and your friend are open to it, please email me at pca@[company].com and I will personally look into it.

Why would an allocation require an atomic write for a reference count? Swift routinely optimizes out reference count traffic.

That's exactly what affine / linear types do.

JS (when using ints, which v8 does) is the same in this respect.

The “tangle of spheres and circles” is probably a reference to the Hopf fibration.

Extraordinary project. I had several questions which I believe I have answered for myself (pizlonator please correct if wrong): 1. How do we prevent loading a bogus lower through misaligned store or load? Answer: Misaligned pointer load&#x2

What's interesting about it is that it supports SPR AVS, which is a new USB power delivery spec. I'm not aware of any other chargers that support this. https://www.chargerlab.com/complete-pd-3-2-spr-avs-specifica..

Doesn't every WASM program have to carry its own malloc/free today?

You're right, thank you for the correction.

My favorite FP Fun Fact is that float comparisons can (almost) use integer comparisons. To determine if a > b, reinterpret a and b as signed ints and just compare those like any old ints. It (almost) works! The implication is that the ne

Affine types, variance, higher-rank trait bounds, phantom data, MaybeUninit, and the whole macro and proc-macro systems are some examples of concepts that I found to be challenging when learning Rust. Dyn-safety is another but I had encount

At $WORK we use SQLite in WASM via the official ES module, running read-only in browser. The performance is very poor, perhaps 100x worse than native. It's bad enough that we only use SQLite for trivial queries. All joins, sorting, etc

Don't confuse "presence of dynamic types" with "absence of static types." Think about the web, which is full of dynamicism: install this polyfill if needed, call this function if it exists, all sorts of progressive

No, it's not so. If the allocation is backed by the kernel, then it will be zero-filled for security reasons. If it's backed by user-space malloc then who knows; but there's never a scenario where a mallocated page is quietly

SIMD is true, but the original guess is correct, and that effect is bigger! using_map is faster because it's not allocating: it's re-using the input array. That is, it is operating on the input `v` value in place, equivalent to th

"Numbers go into the numbers vector" is unusual - typically JS engines use either NaN-boxing or inline small integers (e.g. v8 SMI). I suppose this means that a simple `this.count += 1` will always allocate. Have you considered us

Shells have somewhat unusual parsing requirements. For example "if" is a keyword when used as `if echo` but not `echo if`. So you either need to implement the lexer hack, or have a "string" token type which is disambigua

Rust goes to substantial lengths to allow unwinding from panics. For example, see how complicated `Vec::retain_mut` is. The complexity is due to the possibility of a panic, and the need to unwind. https://doc.rust-lang.org/1
