We’re gathering for a Crystal #Meetup in #Stockholm! Beta Ziliani from the Core Team and Carl Hörberg from LavinMQ will share insights and experiences of using #crystallang. Food, drinks, and tech talks - Feb 18th at Guldbaren. crystal-lang.org/events/2025-st…

I'm giving a talk about #crystallang at #FOSDEM It's going to be an intro, but I'll try not to bore anyone who's already familiar with the language. Hope to see you there =) fosdem.org/2025/schedule/… PS. I'll bring some swag.

Happy New Year, happy new release! 🎇 1.15.0 is out with a new, efficient event loop, support for MinGW-W64 and MSYS2, improvements for BSD platforms, and many more features. Watch out for the formatter changes, they'll likely affect your codebase! crystal-lang.org/2025/01/09/1.1…

And we have a new release: Crystal 1.14.0 🚀 Read about the highlights in crystal-lang.org/2024/10/09/1.1… Happy Crystalling! #CrystalLang #release

Core Team member @ysbaddaden started toying with BLAKE3, trying to assess how much faster it was compared to SHA256 in Crystal… What started as a simple benchmark ended up in a discovery of a performance issue related to structs and its Ruby-based syntax. crystal-lang.org/2024/09/10/dig…

Do you know why @LavinMQ can handle so many connections and process that many messages? There are several reasons, but one of them is because developers can understand the library code the application runs. crystal-lang.org/2024/05/22/lav… #performance #crystallang #lavinmq #programming

Core Team member Johannes (@JoMueFd) will be presenting a talk about Crystal and its use for Rubyists at @helvetic_ruby 💎 Check it out at #johannes-mueller-the-power-of-crystal-a-language-for-humans-and-computers" target="_blank" rel="nofollow noopener">helvetic-ruby.ch/talks/#johanne…

We're happy to announce that Julien Portalier (ysbaddaden) is rejoining the Crystal Core Team. He's working on Crystal at Manas.Tech with a focus on improving multi-threading. crystal-lang.org/2024/02/28/the… #CrystalLang #Multithreading

We're partnering with @84codes to improve Crystal's concurrency model for multi-threading. This is going to be a lengthy process, but it's already bearing some early fruits. #CrystalLang #Multithreading

Crystal sits between dynamic languages like Ruby and compiled languages like C++. Maybe it is a good language to bridge programming language communities... 🤔 Read what Bright has to say: forum.crystal-lang.org/t/crystal-the-… #programming #crystallang #rubylang #cpp

Crystal is getting a more formalized mechanism for discussing language change proposals. This should help to line out which steps are needed and clarify where a proposal is standing. The first order of business is an RFC about the process itself: 🤓 github.com/crystal-lang/r…
