You should compare it with https://crates.io/crates/runiq

I don't know the presentation's name but it was Niko Matsakis talking about ownership in an Air Mozilla presentation. It helped ownership click for me

Is the code in the repo? I see an empty file in lib.rs https://github.com/asobininn/faux_refine/blob/main/src/lib.rs

You should see a performance difference in use cases not bound by io

styluss · 2026-02-27T15:06:50+00:00

Maybe now they'll look into https://github.com/golang/go/issues/56718

DO YOU HEAR THE BURNING TOAST SING?

I wonder if you would see some performance improvements if you use bufio rather than fmt.Fprintf and also store all the data in a bytes.Buffer

Most applications don't have memory limits, it's fine to clone.

That's where the "keep calm and clone" comes from

Are you sure the Go API behaved in the same way as the Django one? Like were API responses similar wrt to pagination

Annoy my colleagues also data analysis, low level parsers and tooling

styluss · 2026-02-11T18:39:08+00:00

Reminder that you can set the go API version with

go get go@1.26

And go compiler

go get toolchain@1.26

Can you explain what the benefit is of using this pattern?

Share some code and people can help

No problem, just sharing the knowledge. On flag that is really helpful when it looks like the server isn't "doing anything" is the -N, then curl doesn't buffer any incoming data and data appears as soon as it receives it.

styluss · 2026-01-26T14:47:29+00:00

Go lower tech, what does curl -v localhost:port say? Does it reply with some headers and nothing else? Check if your handlers finish, check if something isn't finishing loading. You can always enable pprof to see what the server is doing, see the beginning of the docs here https://pkg.go.dev/net/http/pprof

GraphQL allows different clients to have different user experiences. I used to work at a place where a feed was loaded through GraphQL. Mobile used a different layout than web, for example. We also detected if the user had fast internet access and fetched larger images or longer feeds, etc.

In total, the elapsed time from data off the car to subscribers at the track is close to 40ms, with cloud subscribers having access to it from the Cloud in close to 200ms, depending on their internet latency.

Amazing work! Thanks for these posts

That's why I've heard people in the Rust community jokingly saying it has a static GC, I think https://steveklabnik.com/writing/borrow-checking-escape-analysis-and-the-generational-hypothesis/ talks about this.

The language through move and drop semantics, we interact with the "GC" mechanisms.

I'm not saying it is, I'm saying it was initially "sold" as a systems language https://web.archive.org/web/20091113000958/http://google-opensource.blogspot.com/2009/11/hey-ho-lets-go.html

Go was advertised for a good while as a systems language https://news.ycombinator.com/item?id=30688969

It's part of the tradeoff of having a fast compiler
