    Yeah, there's a GH issue thread here that I keep an eye on: https://github.com/crystal-lang/crystal/issues/5430

    I figure whenever windows support lands will be a good time to give it a shot again.

    Still think that crystal might be more interesting in a similar niche?


  • RFC 3339 vs. ISO 8601

    An often ignored part of the standards are how to represent durations (time spans).

    See http://xml.coverpages.org/ISO-FDIS-8601.pdf (section: Representation of time-interval by duration only, pg. 21)

    Would like to see more json parsers in static languages allow me to define a field as a time span and can serialize into the valid format.

    For an example, see this proposal in Crystal: https://github.com/crystal-lang/crystal/issues/11942

        Example:  A duration of 15 days, 5 hours, and 20 seconds would be:

    Technologically robust, making use of open source frameworks that ensure scalability of usage and auditability of the codebase. So, no PHP-based rickety structures or the secret devising of some lone wolf developer. This can't be trusted by anyone: its development must be done in the public repositories. Consider using a Crystal framework such as Amber, which is a compiled-to-binary Ruby clone, lightning-fast (it can handle over 1 million+ requests per second) and compatible with the expansive Rails ecosystem. Or any other solid language base, such as Go or Java.
  • As a Go developer, I’m surprised Crystal isn’t more popular

    There have been 7 releases in 2023 so far (https://github.com/crystal-lang/crystal/releases), one of them (1.7.0) having over 30 different contributors.

    There is also an undocumented Thread class https://github.com/crystal-lang/crystal/blob/master/src/crystal/system/unix/pthread.cr to get at even lower-level multithreading primitives. But can't do anything that touches the scheduler.
  • How Much Memory Do You Need to Run 1M Concurrent Tasks?
    6 projects | news.ycombinator.com | 21 May 2023
    "System time" rather than "user time" is the majority (7.94s system time, 2.83s user time in the 20.25s wall time run). Is this pointing to memory allocations?

    Crystal Fiber docs https://crystal-lang.org/api/1.8.2/Fiber.html says "A Fiber has a stack size of 8 MiB which is usually also assigned to an operating system thread. But only 4KiB are actually allocated at first so the memory footprint is very small." -- and perhaps unsurprisingly, 4KiB times 1000000 is approximately 4 GiB. Nice when the math works out like that :)

    To me this is useful as a baseline for something like a websocket server, with some number of idle connections, each Websocket connection mapped to a Fiber that is waiting for I/O activity but mostly idle.

    I still just document everything using YARD and focus on designing really obvious Object Models and of course write tests. I have tried using sord to convert my YARD type annotations to RBS or RBI, but you still have to fill in missing bits, then use steep and somehow load in RBS/RBI files for other gems and stdlib, and it's just an uphill battle since Ruby is dynamically typed by default. Obviously Dynamic Typing lends itself more to Dynamic Languages, where you can call an arbitrary method and let the language VM figure it out at runtime. Static or Strong Typing lends itself better to compiled languages where everything needs to be resolved at compile time and converted into object code. If I need to work in a compiled language, then I'll use Crystal, which also supports type inference. TypeScript's type syntax is quite nice, but I tend to avoid writing massive JavaScript code bases where a Type Checker helps catch subtle bugs, and instead prefer sticking to minimal amounts of vanilla JavaScriot in order to keep complexity low and not overwhelm the browser.

What are some alternatives?
