@zigo_101 To be fair, you could replace Golang with any other programming language, and the sentence is still true. There’re rooms for improments, though.

IMHO, there are so many subtle details in #Golang semantics and the official compiler/runtime implementation that it is not easy to maintain consistency. Small modifications in one part of the code may inadvertently impact other areas, and the impact might be not found in time.

My new blog post about bug in new range-over-func since go1.23: cuonglm.xyz/post/go_issue_… This will (likely) be fixed in go1.23.2

The current compiler implementation will print 0 2. However, the value of x is unspecified, only y value is guaranteed to be 2.

What's output of this program: package main type I interface { M() int } var x = I(S{}).M() var y = (S{}).M() var z = one() + 1 type S struct{} func (S) M() int { return z } func main() { println(x, y) } func one() int { return 1 }

Breaking my Twitter silence because @junyer has passed away, and this is the site where he was most active. I know we had at least a few followers in common. There is a public memorial page of sorts at github.com/google/re2/iss….

@go100and1 Should be fixed after go-review.googlesource.com/c/go/+/560575 landed.

An inconsistency in the current official #Golang compiler. Here, g compiles, f doesn't: func main() { f(0) g(0) } func f[T byte](t T) { const S = "a" _ = S[unsafe.Sizeof(t)] } func g[T byte](t T) { const S = "a" _ = S[unsafe.Sizeof(t)+0] } github.com/golang/go/issu…

@go100and1 That’s with old (buggy) inline static init implementation. The correct one (tip) must make it compile ok, raise runtime error when running.

@cuonglm_ Your blog article says it will raise a compile-time error. Or I misundertand it?

Inline static init will be enabled again for go 1.21 cuonglm.xyz/post/inlstatic…

@go100and1 It’s a legal program, why?

@cuonglm_ It looks the tip toolchain deesn't report errors for var x = f(-1) func f(x int) int { return 1 << x } Need compiler flags to enable it?

@go100and1 No, `f(-1)` is not a constant.

@cuonglm_ Will const x = f(-1) func f(x int) int { return 1 << x } compile?

@XorNinja Is there a video recording for the session?

Here you go: Fantastic Crypto Bugs and Where to Find Them #slide=id.g228b0426239_0_0" target="_blank" rel="nofollow noopener">docs.google.com/presentation/d… This is pretty basic, but we did find a bunch of bugs during our live demo =) Somebody afterward showed me a padding oracle bug in an important chat app, so I guess the idea works :)

@GoLandIDE Will this be fixed in this release? youtrack.jetbrains.com/issue/GO-14538…

GoLand 2023.1 Release Candidate is out! We’ve updated the Code Vision feature. GoLand now shows the number of implementations for an interface and its method specifications. 🔗 blog.jetbrains.com/go/2023/03/24/… #golang

@favadi Or shorter, perl is written once, run everywhere!

Everything I saw developers struggle to make awk and sed works om both Linux and macOS, I gently remind them that perl is available everywhere and work the same on all platforms.

@favadi go 1.20.1 is released 😎

@cuonglm_ The wisdom is hold on upgrading until .1.

A note if you are going to upgrade your project to go1.20 toolchain. cuonglm.xyz/post/inlstatic…

Is anyone really sure that @golang actually added generics vs. just putting them in the documentation so people would stop complaining?
