I guess I enjoy solving problems, and recognize that the devil is always in the details, so I don't get much satisfaction until I see the whole stack working in concert. I never had much esteem for "architects" who sketch so

So are Cygwin and WSL, though, for those who don't already have the luxury of being on Linux or UNIX (incl. MacOS). I'm sure there are uses for running full-system emulators inside a browser, but access to bash and sed and gawk d

I agree, bash, sed, etc. are great, but a VM running inside a browser seems like the least efficient way to access them. Even if you're stuck on Windows, Cygwin has been a thing for 30 years now, and WSL for ten or so? There should b

But Docker is free (unless you're a fairly large business, in which case containerd is still free, and you can either pay for the front-end license or figure out how to set up one of the free alternatives), and from what perspective ar

The problem is that C++ stores the vtable inside the object, and the objects over which you're iterating often weren't allocated contiguously. Even when they are, if each object contains lots of other data, the vtables won't

And how does one become a maintainer, if there's no way to contribute from outside? Even if there's some extensive "application process", what is the motivation for a relatively new user to go through that, and how do t

If the goal is truly "clarity", then I fail to see how this leads to more readable programs than Knuth's Web (or cweb for a more practical implementation). If you really mean "C/C++, but with the sharp pointy bits f

The "founding engineers" behind Facebook and Twitter probably didn't set out to destroy civil discourse and democracy, yet here we are. Anyway, "full control over your keys" isn't the issue, it's the way t

That's not a great example, since memcpy() already has all the information it needs to determine whether the regions overlap (src < dest + len && dst < src + len) and even where and by how much. So pretty much any qualit

That's actually a terrific example, because the company already had a working, field-tested manually controlled version of their product, but they wanted a computer-controlled version to relieve radiologists of all of the drudgery and

Modern CPUs do out-of-order execution, which means they need to identify and resolve register sharing dependencies between instructions. This turns the notional linear model of random-access registers into a DAG in practice, where differen

Finding defects is a good thing, and fixing defects is a good thing. Adding new features can be a good thing as long as it doesn't introduce or uncover too many new defects in previously stable code. But what is lacking in your devel

This is exactly how technical debt accumulates. You can write a comment documenting that "unsafe is actually safe here in routine X because Y will always do Z," but if the code lives long enough, someone may eventually change X o

I've often wondered how the evolution of C and C++ might have been different if a more capable preprocessor (in particular, with more flexible recursive expansion and a better grammar for pattern matching) had caught on. The C++ templ

Amdahl's Law, like most 20th-century performance "wisdom" and metrics, focuses excessively on instruction count, neglecting memory and I/O pressure. 64 cores doesn't mean 64 independent cache pyramids and memory bu
