No problem; I'm glad to be helpful.

CPUs can execute arithmetic instructions fast, because we've been trying to execute sequential instructions faster for years. One way to do this is to create a pipeline: while the result of one instruction is being calculated, start re

You seem unreasonably angry at this article for not immediately denouncing capitalism, and ignoring any possibility that there's a cultural aspect. The free market is not a new concept; why wasn't the birth rate as much of a probl

The post is from 2022. However, looking at the table of contents [0], she seems to spend a lot of the book on types and pointers. That's cool, since the compiler books that I've seen don't cover languages with pointers and po

Most programming languages today don't have dynamic scoping. Here's something you could do in a language that had it. print_x() { print(x); } foo(msg) { let x = msg; print_x(); } main() { let

Because they threaten, harass, boycott, and stir up bad PR? You're suggesting the only recourse for people like Aleta would be to defame, boycott, and threaten violence against these people even further. It's medieval.

The idea behind a free market is to use the desire for profit as an incentive for the self-interested to collaborate with others and serve the public interest in doing so; this is why the state promotes the formation of businesses and punis

That reminds me of this program, which calculates the month and day given the year and the day of the year [0]. There's a version that abuses goto, and one that stores state in variables and only uses structured statements. You probabl

It could be a mistake. I've accidentally flagged and downvoted comments before and then only realized it when looking at the list of comments I've flagged and downvoted. I'm more careful now, though.

That's pretty cool; thanks for showing me. I guess x86 instruction encoding isn't as bad as I thought, then.
285.
by trealira 2y ago
Admittedly, I never wrote an assembler, but the encoding of x86-64 seems pretty convoluted [0] [1], with much of the information smeared across the some bits in the Mod/RM and SIB bytes and then extended by prefix bytes. It's more
286.
by trealira 2y ago
Studying the x86 architecture is kind of like studying languages with lots of irregularities and vestigial bits, and with competing grammatical paradigms, e.g. French. Other architectures, like RISC-V and ARMv8, are much more consistent.

Thanks, that's a good case. Actually, the JavaScript semicolon insertion algorithm [0] seems more complex than I had remembered. I had thought of them as variations on the semicolon insertion in BCPL, but it seems like that's an o

by trealira 2y ago
Haskell also inserts semicolons, but it has a different rule, which I think is a bit interesting. If the current line starts on the same line that the previous expression started on, then a semicolon is inserted at the beginning of the curr

by trealira 2y ago
What makes Go's semicolon insertion algorithm different from JavaScript's? They seem similar to me. Isn't it just that the Go compiler requires very strict formatting, which saves you from getting bitten by errors due to unex

To be fair, that's not actually in the book. I said it was based on a function from that book, but below is the version they actually write in the book; I apologize for unintentionally misleading you. I wrote the above function myself

The C language seems to really like reading/writing data and then modifying it, or modifying data and then reading/writing it, which can make for some dense one-liners full of side-effects. The pre- and post- increment and decreme

I would recommend the book Haskell in Depth , which covers both of those topics (monad transformers by chapter 6, lenses in chapter 3 and chapter 14). It also covers some other advanced features, like Template Haskell and concurrency, and

Typo: that line with "cbnz" should be "cbz". The CBZ instruction branches to a label if a register is zero, and CBNZ branches if the register isn't zero.

I think we just define functional programming differently. How do you define it? Also, I just noticed this part again: > Honestly the hardest thing learning OCaml was figuring out where to put the brackets and semicolons. I am 100% serio

I'm surprised they didn't try something less clever to optimize their code first. The assembly code could be rewritten like this, so the test requires one branch at the bottom of the loop instead of two (one to jump to the top and

One reason you might want an explicit keyword is so that it fails to compile if it can't be calculated at compile time, which is what was intended, rather than fall back to calculating it at runtime. It also seems useful as an ad-hoc m
