Yep, exactly like that.

No, each request is handled concurrently in the same thread using evented IO. You spawn fibers, which are the analogue to go's goroutines, and many of those run in one thread. Just like nodejs (without callbacks/promises/asyn

Probably because they loved the language. Humans are humans, and not everything is made with a rational financial decision. If you use the language, and like ruby and static typing, you'll find that there's a lot to love.

You can't use rails with crystal, the keyword is "rails-like".

While elixir's syntax is inspired by ruby, the semantics are vastly different. That change in semantics is really good for elixir, because it means it can take advantage of the unique properties of the erlang vm, but it's worth no

Crystal has had concurrency, almost identical to goroutines, for a long time. It's just as if you're always running with GOMAXPROCS=1. And you can still get some excellent performance on IO bound workloads with a single core. The

Crystal's multi threading model will eventually be exactly the same as go's, not ruby's, but yes its not done yet.

It's not official, largely because it's a big hack.

All the goroutines share the heap, so go does support shared memory, it's just you're encouraged to use channels instead because they're easier to get right.

But crystal support concurrency, and it supports it very well. That's why it achieves about 100,000 HTTP requests per second per core, you just can't get that kind of performance on a single core without using evented IO.

Crystal is still fairly early in it's development. We have plenty of time available to make the breaking changes required to make windows a true first class citizen. I'm putting a lot of thought into how to do this.

Manas is a tiny company without the resources to spare a single developer. The money to pay for the single developer who is working full-time on crystal comes entirely from bountysource and other donations: https://salt.bountysou

Crystal will eventually have go-style parallelism as well as go-style concurrency. It's a hard thing to implement, and we don't have the resources of google (in fact we have very little resources at all) so it's taking time.

it's not very very soon - it'll be more than 2 months - but it is coming.

Every project has it's warts, long running feature requests, and it's bugs so minor nobody's gotten around to fixing them. Some projects decide to hide those by closing the issues, we generally keep them open, because they ar

I think you're getting confused by concurrency and parallelism. Crystal is concurrency-first and uses the same concurrency model as go. Expanding that to run fibers on multiple cores is just an implementation detail. A difficult implem

Crystal has the foundation for parallelism, it has the same concurrency model as go. Adding parallelism will happen before 1.0. Adding parallelism to crystal is easy, it's already been done in a branch and it works fine. The problem is

No, it's not because it's compiled, it's because of the global type inference algorithm (which is very different from any existing type inference algorithm). Crystal used to have a repl but it was removed because it was buggy

The number of open issues is a bad correlation for how well a project is managed: rust has nearly 4000 open issues. Most of these are either feature requests we'll get to some day, or minor bugs. Crystal development is proceding nicely

Wsl is getting scarily close to Linux performance in benchmarks and improving fast. I don't see extend being too far away...

"the inbox" refers to a HTTP endpoint required by the activitypub spec. He's just saying that pixelfed can't receive messages from other AP instances, so he disabled it sending messages to other AP instances too, to avoi

To be fair to bcache, that bug wasn't in the bcache code. It was in core kernel bio code and could easily have effected other subsystems.

Bcachefs is being upstreamed into the linux kernel(lwn.net)

Yeah, crystal has one of those (and it's about to gain exhaustiveness checking), so I didn't literally always mean `if/else` :)

Pattern matching, at least in functional languages, is mainly used both as control flow to match on the type of arguments, and also to destructure data structures. In flow typing you replace the control flow part of pattern matching with `i

I'm pretty sure the article implies this is for user-facing applications where the user would manually extract it once to a place of their choosing then run it from there. I think you're missing the point of the whole article.
