Re. Go. I've turned this code into a Go benchmark and run it with both the default cmd/compile (1.11) and gccgo (8.2.0). cmd/compile: BenchmarkFib-4 1 16530409619 ns/op PASS ok command-line-argument

That is compiler compatibility. I am talking about language-level compatibility. Yes, you can continue compiling v3 code with a v4 compiler with a flag, but if you compile your v3 code without a flag, your code may fail to compile. So while

>Swift 3 -> 4 code is compatible Is this really true? Looking through 4.0 release notes I see some incompatible changes like: SE-0164 Remove final support in protocol extensions SE-0160 Limiting @objc inference If your code c

My memory might fail me, but I thought Swift 4 was supposed to be "the last major breakage"? Swift has a new major revision every year. Compare this to Go (no major revisions after 6 years, probably a backwards-compatible major re

Sure. In Go, this was one of the details that cemented my love for the language. Imagine you have a multiline list, sorted alphabetically. strs = [ "a", "b", "c" ] If you don't have a

This is indeed very sane. One thing I personally would change is making a trailing comma in multiline lists obligatory, like in Go. I hope this gains traction, so that I could use it in my projects without people being upset about "som

What I meant is, when did they start the switch, and which versions have already switched.

by ainar-g 8y ago
When did they switch to Clang? The about:buildconfig of my Developer Edition (Ubuntu) shows GCC 6.4.0, without -flto obviously. On a related note, I wish they would add the information about the Rust compiler used to compile the components

I recall reading somewhere that the code of SQLite also has some UB. Which makes me wonder, if they use runtime sanitizers, like ASan, UBSan, etc.

IIRC, fasthttp only supports a subset of HTTP. This may or may not be a deal-breaker for some people.

Re. syntax. I don't understand, why can't they just make _Ptr an attribute like _Atomic, and provide a header <stdchecked.h>. That is, #include <stdchecked.h> void read_next(int *b, int idx, checked int *out) {

WAT 3 and WAT 10 were surprising for me. WAT 3 becomes less surprising when you consider that a method on a pointer can be called and can return a valid result even if the pointer is nil. WAT 10 just seems inconsistent. I said this before,

This may be a rather intrusive question, so I don't really expect an answer, but how is the market for commercial static analysis tools? I am asking because I was thinking about creating such tools myself in the future, preferably goin

I think they meant literal generation of files based on templates. Basically sed 's/T/int/g' file@T.go > file@int.go Some people do that, I guess.

by ainar-g 8y ago
Depends on the environment, I guess. I've been programming Go professionally for over 3 years, and I've never used such "templates" for generic types. As I've said in another thread, I've had a need for sum typ

Yeah. I always try to include some context with my errors, so the only actual uses for check/handle I have is handle err { log.Fatal(err) } in quick "scripts". And even there I should probably provide more context. All

Even if you do use arbitrary precision arithmetic and count nanoseconds, the heat death of the universe is more likely to occur before your number takes 1KiB of RAM.

Right, thanks. My estimate was closer to 200 because I was thinking of Go's time.Time.UnixNano method[1], which returns undefined results when used before the year 1678 or after the year 2262. But yeah, if you count since the system re
