I'm so glad the new uuid package landed - it's overdue but a very welcome addition! I've already replaced github.com/google/uuid with `uuid` in several projects
You might want to follow this proposal, if you aren't already. It's the most recent one, and it's supported by quite a few “core members” of the Go Team. I don't think it'll land in 1.28, but I like the fact that it's still a feature that's being actively discussed.
Go is extremely easy to pickup. If you know any language you probably know Go already for the most part (channels notwithstanding).
I wouldn't say it is a "beautiful" language however. Though that is in the eye of the beholder, I don't think the Go designers were even really going for beauty.
That is a LOT of code (very ugly code, I would add) that could be replaced by `type Float = float32 | float64` in a language with actual support for union types.
Tagged unions are not union types. A union type is a supertype for any arbitrary collection of types, but a tagged union is a single type with multiple data constructors, and does not require subtyping to be implemented.
Having worked a couple of greenfield go shops post generics, it’s still quite rare to find them in first party code. They’re just not that useful outside of library APIs. Proper algebraic data types would be a huge game changer.
I’ve been able to run golangci-lint locally just fine.
However I’ve not had much success running it on CI, with at least the 1.27rcs. I encountered some panic deep within staticcheck, and ended up turning off that specific linter on CI (better than not running it at all).
There was a tracking issue for go1.27 support at [1].
However that is now closed, which might imply that it should be working.
I like to imagine that one day we'll have a language that launched with all the features languages eventually add. The whole ecosystem of packages would be built on them instead of a legacy of more primitive language feature sets.
I mean one thing frontier models are really good at is porting code with pretty low level of supervision. Provided there are enough fans porting packages from other ecosystems should not be a big challenge.
> Second, a key in a struct literal may now be any valid field selector for the struct type, allowing fields in nested or embedded structs to be initialized directly
It's been a while since I've written more than anything trivial in golang, but this seems like a big deal to me. As in, I can define a struct that is consistent and reusable in other structs
It will be very nice working with code generators like oapi-codegen that can generate either nested structs or very unwieldy struct names. So big in that context, but like you said just a nice qol improvement most of the time.
I love how proactive the crypto team is about post quantum. They released https://pkg.go.dev/crypto/mldsa. The lead maintainer Filippo Valsorda wrote a nice piece here[1] to urge the tech world to start deploying good enough versions of post quantum crypto.
While I'm highly sympathetic to competing priorities crowding out movement to pq cryptography. At the same time it's not sudden at all. It's been 10 years since nist first said "move shit over"?
"bold-faced lie" and "bald-faced lie" are both valid expressions. The original expression is "bare-faced lie" but they're all pretty similar to each other.
bold-faced lie is just the usual English drift that was actually questioned as incorrect when it first surfaced. If a lie is bold, you don't have to suggest that the user's face is bold when doing it. You can in thirty seconds of google searching find numerous sources explaining that "bold-faced" is a malapropism.
It's the usual English drift perhaps, but "bold faced lie" has been used since the 17th century, which is also apparent from "thirty seconds of Google searching". Three hundred years is enough usage for me to count it as correct.
On a side note, "bold faced" does not mean the persons face is bold, only that it is said boldly, which implies a level of rudeness that "bald-faced" or "bare-faced" does not.
> Generally, something to be avoided by people striving for clearer communication
Their communication seemed pretty clear to me. If anyone actually claims that they didn't understand what they meant but would have understood it by using the other form of the expression, I think that's a bold-faced lie.
Modern references seem to align (for instance, Garner's): Bald-faced and bare-faced have slightly different connotation than bold-faced. Despite "bold-faced lie" being in somewhat common use, "bald-faced lie" is more common (over 2x according to google stats), and overwhelmingly agreed upon as the "literate" choice, unless an author intends to refer to the sort of lie that would headline an article.
Yes but only one of them makes most people who hear it think you don’t know the expression you’re trying to use. There’s no objective reason it has to be this way, but it is, and at least personally I appreciate being told when I’ve got something stuck to my back.
I don't really know why I should care what expression I'm trying to use (or what someone else is trying to use) as long as the intent is understood. If anything, people who are needlessly pedantic about the way I express things that they clearly understood are people I'm happy to get signal from so that I can minimize my need to interact with them going forward; it's much nicer to find out from something inane like this than to wait until we have a communication problem about something actually important.
Chromium uses BoringSSL, which opens its readme as follows:
> BoringSSL is a fork of OpenSSL that is designed to meet Google's needs.
> Although BoringSSL is an open source project, it is not intended for general use, as OpenSSL is. We don't recommend that third parties depend upon it. Doing so is likely to be frustrating because there are no guarantees of API or ABI stability.
This person was public on the recent nist list against hybrid solutions. I simply don't understand why they would oppose the safer option. Yes I've read the mailing list, it just all seems quite suspicious.
> First, generic methods are now supported
> Generic functions can now be used without explicit type arguments
Great! This was an ergonomic code issue I hit when trying to create a universal handler/controller generic that could hydrate/populate function arguments (from a request body) without having an actual copy of the arguments: https://github.com/xeoncross/mid/blob/main/handler.go#L12
Thanks for the link, looks like a very pleasant framework to use! I was interested to see "Mid-fasthttp" on the slower end in the benchmarks at the bottom, do you know why that is?
Btw, the Gin and Echo examples reference an "input" variable but it doesn't seem to be defined there? Maybe it was intentional, since the examples are just to give a general idea of how the handler looks in each library, but thought I would let you know just in case it wasn't.
Due to the fact that fasthttp is not net/http compatible it is due to the conversion being required from a https://pkg.go.dev/net/http#Handler. It was included for information purposes as I though someone would be curious.
I love Go because even minor versions deliver great value like this. The struct literal inits and generic methods are great conveniences to clean up clumsy boilerplate.
Not to mention it’s just a dream language to work with , especially when building concurrent applications. I love engaging all of my cores. And memory is so expensive nowadays
Minor versions are basically major versions for Go. They’ll “never” create a Go v2 because they prioritise maintaining backwards compatibility as a language feature, thus following semver rules, no majors.
Unfortunately for people SELECTing UUIDs out of a DB directly into a uuid struct, the built-in uuid structs don't implement the necessary interface for that, so you'll have to continue using the google package, or a plain string.
The database/sql package gained native support[1] for the uuid.UUID type so it will Just Work even without the methods. This probably should have been mentioned in the release notes and database/sql package docs.
Repeating the package name is fine if it's exactly the same name (modulo capitalization) and there's nothing better to name the type anyway. The style issue would arise with e.g. uuid.UUIDVersion, which should just be named uuid.Version. There used to be a gopls lint that would flag names like uuid.UUID but it got relaxed awhile ago.
uuid.UUID is implemented as [16]byte, like most other UUID implementations out there.
If you want to keep your package implementation agnostic, use [16]byte as argument type; that's assignment-compatible with any other type that is such an array underneath:
One of my engineering highlights was Russ reviewing a few of my contributions to Golang (to the core http library). He's a super cool and nice guy. I don't really write that much Go anymore, but it was a fun & cute language when it first came out.
I once wrote him an email asking what font was used in the plan9 papers. He replied. It's Lucida Sans Unicode. He even provided a url to paper published by the maker of the font.
Zmij and xjb are in a league of their own. Broadly speaking, dtoa first has to find the shortest decimal representation of the floating-point input, and then format that decimal representation into a string. Zmij and xjb pull far ahead of the others mostly by speeding up the second part of that process.
uscale is quite good without the stringification, as are many other algorithms. I would say uscale's main strength isn't its speed, but rather its simplicity and, more importantly, the fact that it does both formatting and parsing using a single ~11 KiB table, which no other algorithm offers (although yy comes close).
The core of newer methods like yy, xjb and zmij is remarkably simple: https://vitaut.net/posts/2026/yy-dtoa/. Shortest uscale is basically Schubfach or, rather, it's variant called Teju Jagua and has 2-3 wide multiplications compared to 1 for newer methods.
The complexity is optional and comes from squeezing the last few nanoseconds =).
Right, that's basically what I was trying to say (in so many words). I learned a lot from your dtoa blog posts and Zmij's implementation. Thank you!
> has 2-3 wide multiplications compared to 1 for newer methods.
As written, the `shortFloat()` function always calls `uscale()` two times, followed by an optional third call. Each `uscale()` does two wide multiplications (one full 64x64->128 and one 64x64->hi64, in case we want to make that distinction), so that works out to either 4 or 6 wide multiplications in total. I think `shortFloat()` could be rewritten to always do exactly 2 wide multiplications (both 64x64->128) at the cost of some more ALU operations. However, I don't see how that could be further reduced to only one wide multiplication without significantly altering the algorithm.
Agreed. I've recently translated a pangram generator project written in Rust [1] leveraging SIMD to do the same in Go [2] to see how it fairs in terms of speed - the results are pretty close. In my local machine I'm getting ~3GHz in Rust vs ~2.5GHz in Go, which I think is really impressive.
I still believe that SIMD support is one of the most underrated new features in Go.
It's relatively straightforward to read and to write code using Go's SIMD package (the caveat being that you have to convert your data to SoA manually), and it gives comparable performance to other languages, since there's little in the way of GC overhead, bounds checking, etc, in this case.
So SIMD not only increases performance on its own, but it also closes the performance gap between Go and C++ / Rust, which has been a major cause for rewrites in the past. The memory usage overhead due to GC doesn't go anywhere of course, so there are still performance reasons to "Rewrite in Rust", but it's now become much easier to just optimise the hell out of Go code instead.
This was one of the times where it made some sense. A lot of their complaints were about GC, which Discord has had issues with in the past on other things. Notably, Discord switched from Cassandra to ScyllaDB for their messages, and cited the Java GC as a big reason.
Odin solves this by letting you declare all arrays as either normal (AoS) or SoA, which helps with this use case a lot. Otherwise very similar ideas, except all the memory goodies. Underrated language!
Wasn't Go supposed to be "simple"? I remember how Go advocates used to boast about not having generics and now it almost seems like Go is trying to become some sort of C# or Java Frankenstein. I'm not even trying to badmouth Golang - just legitimately confused.
> almost seems like Go is trying to become some sort of C# or Java Frankenstein
The original Go team was trying to avoid this:
"Java, JavaScript (ECMAScript), Typescript, C#, C++, Hack (PHP), and more [...] actively borrow features from one another. They are converging into a single huge language." [0]
That team has since moved on, and now Go has begun to join that convergence.
The problem is that most programmers seem to want to write Java, more-or-less. New, simpler languages come along, but once they get popular, the pressure is on to turn them into Java-likes. It happened to Python and now it’s happening to Go. It takes a strong will for language maintainers to say “no”, and their language will suffer in popularity as a result - see, for example, Ruby.
I would argue that languages like Java (C#, Kotlin, etc.) strike a very good compromise between modeling ability and comprehension, which is why they are popular and people gravitate toward them.
You can have more complex languages like Scala that provide stronger modeling ability, but at the cost of complexity. Golang started off as extremely naive/simplistic, and is now converging in some ways. But it still has a ways to go: no generics on interfaces, no unions/ADTs, no pattern matching, no proper enums, error handling leaves much to be desired, and much more.
idk, hn is the only place I every see people actually not liking go and most times those are people who's job is just far away from fields go is being use in.
I love these release notes but I really wish they would add syntax highlighting to the Go blog. I'm always a little bit surprised/disappointed whenever I land on a go.dev link since I know the code will be just a little harder to visually parse than it needs to be.
There's a reason for this. Rob Pike was asked about it and said that syntax highlighting reminds him of the bright colors of children's toys and he personally disables it so that he can focus on the text.
I don't know why it's still like that but that's the original reasoning.
that's an extremely odd explanation and it makes me think that he has some hidden PTSD. it's also insane that one person's preference trumps the rest of the world's.
I understand and respect this position. I think syntax highlighting
is a highly subjective matter, bordering on personal preference with regard to shell interactions, editor configurations, bindings, shortcuts, snippets, and the like. It's also... insignificant somehow, like quibbles over formatting rules that Go settled once and for all with `go fmt`.
I often prefer not to enable syntax highlighting just for color. Occasionally I'd choose some minimal theme that only highlights string literals and keywords. So it has two or three colors. But some of the color schemes I see are a festival of lights where every special element of syntax has its own color.
I don't understand how that is supposed to help me parse anything and why the rules are complex. The `range` keyword needs to be purple, and `chan` must be navy blue. Why exactly? And every site has a different color scheme? There is no consensus, and there shouldn't be.
For a serious community-driven project like Go, dealing with the question of syntax highlighting is strange. The creators deliberately avoided the questions of IDEs and editors for Go, leaving them to the community. I think the same principle applies here.
Unlike formatting preferences, the colours I use in my editor don't effect others. That said I might not mind living in a world where everyone used the same highlighting scheme, as long as it was reasonable ;)
When I started learning Go I went all in including using the recommended editor (acme editor) which has no syntax highlighting, no autocomplete and a very different way of writing code. My production went down a lot but the quality of the code went up a lot.
I think the lack of syntax highlighting was one reason for that. It makes you think more about the code you write and how it should compose, while a fully fledged IDE encourages you to just throw more code at the problem.
I think the ACME way should be used for love of code and ideally when you want to create libraries that stand the test of time.
When you just want to get things done fast bring the full IDE and now some LLM vibes and it’s done.
I think there's a lot of value to be gained from turning all modern day features off for once and just code "raw", no syntax highlighting, just typing out all the code. Doesn't even need to be your own code, manually transfering code over can also help a lot with your basic coding skills.
I think a lot of people lose this over time because it's easier to use templates, autocomplete and LLMs, work from a higher level. But it's nice to go back to basics. Consider also firing up Pico-8 and writing some really really bad code. It's got a very rudimentary editor, 40 columns of code, no syntax highlighting, and you're limited in how much total code you can write. It also helps with leetcode since a lot of leetcode uses game coding tricks like modulo operators, min/max/clamp, etc (that's as far as I got, don't judge).
The Go language is by itself more than enough to get a trademark. They only additional thing you can do with a font is get a design patent... for the font.
It's more likely that they don't feel the need to use the font they gave you (for your code editor) on code samples on their own web pages. As it's a custom font, the text would be susceptible to pop-in, or would visibly switch from one font to another, both of which are ugly.
So they have no specific font preference for code samples, they only show their Go-specific font on the blog post about it. They prefer fast loading and no jank over custom font.
I get the why, kind of - if you need colors to make sense of code, maybe the code isn't clear enough. If you send blobs of code through email and other systems that don't necessarily have syntax highlighting, it also makes sense. But on a website, whyever not?
Personally I can't say when I was last actually aware of syntax highlighting. The only time I'm actively engaged with it is to change the default low contrast comment color that a lot of themes have (for some reason, as if comments are unimportant / noise) to something better. For Go, I don't really notice when it has or doesn't have syntax highlighting, at least not on e.g. go's website.
Used to code primarily in Java. Now my app stack is about 80% Go. I love that it enables lightweight application development. Glad to see the platform evolving with a focus on resource efficiency.
Non-cooperatively terminating a shared-memory thread is an inherently unsafe thing to do, and basically every runtime that has an API for it regards it as a design mistake. See, e.g., https://docs.oracle.com/javase/8/docs/technotes/guides/concu... and https://learn.microsoft.com/en-us/windows/win32/api/processt.... (POSIX's pthread_cancel is somewhat different, and avoids some of the worst failure modes, but at the cost of not actually consistently killing the thread when you call it—and it still has a lot of problems besides that.) So I don't think Go is ever going to add this, nor should it.
(Having the go statement return a handle that you can block on would of course be completely fine, but at this point they're probably not going to do that either.)
You can't terminate goroutines like individual threads, but there's no good reason to anyway. They designed the context system to be able to signal across goroutines and do cleanup that way
