Well, have you observed that behavior first-hand? Did someone you know and trust observe it first-hand and tell you about it? Etc. We don't ask you to "prove" anything, but some more information instead of vague hints would b

They asked for any evidence beyond "it's like this, trust me" and you answered with "really, it's like this, trust me" . Do you realize that if someone isn't convinced after the first "trust me&quo

"Chesterton's fence" doesn't mean that you should never change or abandon an existing tradition. It means that you shouldn't do that until you understand why the "fence" was put up in the first place.

Why would you use GNU parallel if you have to implement your own non-trivial pre- or post-processing logic anyway? Just spawn the worker processes yourself. GNU parallel is great if you have, e.g., a bunch of files, each of which needs to b

... and it uses a manually implemented post-processing step. You can't just run the sort program with GNU parallel and expect to get a fully sorted list.

So, like this? codecs.decode(b'616263', 'hex') If that's correct, what's so hard/bad about this?

> exponentially easier Exponential in regards to which variable? Money? Time? Effort? Or did you simply mean "vastly"? This may be nitpicky, but we should expect people to get basic terminology right – at least on HN.

But it's a much more compact than that glibc monstrosity is. Sure, the glibc version will win in a micro-benchmark, but micro-benchmarks don't capture the effect on the instruction cache.

An optimizing compiler will turn div-by-constant and mod-by-constant into multiplications and bitshifts. For example, the Rust compiler: https://play.rust-lang.org/?version=stable&mode=release&edit... (select "

Compiling several tools into a single binary doesn't violate that guideline: each tool still does one thing. Being single-binary is an implementation detail.

For most people, the time/money tradeoff isn't very flexible. Only few have the choice of working fewer hours for less money, while even fewer have the choice of working more hours for more money.

Fabric = data transmission infrastructure between CPUs or cores. This includes the wires which carry the data signals, as well as routing logic.
