With Discourse, you can enable mailing list mode and read all the Discourse instances from your email client. That’s what I do. Personally, I only have one Discourse instance I keep up to date on, but if that instance weren’t right there i

Yes, but it's not so uncommon for "spinlocks" to evolve into not-actually-spinlocks while keeping the name. In the Linux kernel, `spinlock_t` is actually a mutex if `PREEMPT_RT` is enabled [1]. And Darwin has some code to d

> No, this is definitely not how atomics with memory orderings work. If you do two atomic reads, the CPU will do two load instructions. Neither the compiler or the CPU is allowed to optimize this. Yes they are. And other optimizations a

In this particular case, the mutation being added to the original SARS-CoV-2 is one that was already present in Delta. So if someone were to replicate this with real virus (as opposed to the non-infectious particles the existing experiment

Personally, my inner voice doesn’t narrate; it only makes logical arguments or explanations. But it does occasionally seem to ‘go on autopilot’: my conscious focus is on some pressing but mindless task, and then I catch my inner voice in t

Suppose you have a function `a` that calls two other functions in succession, `b` and `c`. Further suppose `b` and `c` each have one large stack variable (e.g. an array). Ideally we should be able to reuse the same stack memory for both v

It depends. For one thing, constexpr guarantees that errors will produce compilation failures. (At least it guarantees that when used in certain ways; unfortunately C++ overcomplicates things.) In a version of C that doesn't have an

Just as a starting point, you can look at any existing uses of #define to either define a constant or define a ‘function’ that can be evaluated at compile time. For constants, #define is ubiquitous and works fairly well, but it has several

For me this is analogous to, say, a PC running a NES emulator. You can talk about the emulated CPU. Its state: its 8-bit register values, the contents of its 2KB of RAM, what 6502-architecture code it's currently running. Its concept
