1. Crystal for the community: a journey in the Brazilian community
2. Introducing Guto IT Technician and Future Bachelor of Science in Information Systems from IFSP, Software Engineer at Nimble, Open-Source Enthusiast, UNIX lover, Member of He4rt Developers and Brazilian ambassador for the Crystal programming language @lanjoni @gutolanjoni @gutolanjoni For more information visit: https://lanjoni.dev aka João Augusto Lissoni Lanjoni /lanjoni
3. Starting at the beginning… When I discovered the Crystal programming language
4. How did I meet? • Pandemic (2021) • Studying Ruby • Release of version 1.0 in March • I was interested in how Crystal works
5. How did I meet? • Since my first contact with the Crystal programming language, I was interested in starting projects that used it.
6. How did I meet? • Therefore, the first major project I did for the Brazilian community brought me even closer to being recognized as an ambassador
7. Okay, but, ambassador? What are? Where they live?
8. Ambassador s In a general context, ambassadors are people who represent a brand or company, for example, in which their style of coexistence is aligned with promoting the image of a certain brand!
9. My role My role as an ambassador for the Crystal programming language is to evangelize, spreading the image and knowledge about Crystal to the world, seeking to produce content (such as articles, videos, lectures, courses, among others) focused on this area!
10. How did I get it? Building something from the community for the community.
11. 4noobs By participating in the He4rt Developers community, I was able to build the “Crystal4noobs” guide!
12. Crystal4noobs • The guide is a complete roadmap for an introduction to the Crystal programming language, written entirely in Portuguese! • The project was published and disseminated with support from the He4rt Developers Community.
13. So the best happened Yes, that's exactly what you're thinking
15. This was the first impulse to produce even more content
16. Beginning of the journey as Brazilian ambassador
17. First talk • My first official presentation talking about Crystal took place at the VIII COTESI (Information Technology and Systems Congress) in May 2023.
18. First talk • In this presentation I introduced how the Crystal programming language works in practice.
19. First talk • As the conference took place at the university, I began to notice some valuable points that would make Crystal an excellent option for teaching.
20. First talk • Compiled • Object Oriented • Integration with LibC • Type inference • LLVM
21. First online presentation
22. He4rt Spaces
23. First big project What was the first big project with Crystal that I started?
24. First big project • ScyllaDB is a NoSQL database based on Cassandra, in which I started building a driver to be used with ScyllaDB, with the aim of better using the features that are offered.
25. First big project
26. In-person events In all these in-person events, I somehow spread awareness and evangelized about Crystal
27. ROADSEC 2023
28. CPBR15
29. FRONTIN SAMPA This is me with the people from the ScyllaDB space commenting exactly about scylladb-crystal-driver
30. LATINOWARE 2023
31. Online events
32. Learn4Elixir The entire event was about Elixir, however, I gave a presentation talking about Crystal!
33. Open-Source projects Open-source projects with Crystal that I contributed to
34. Emacs LSP mode For Emacs users, lsp-mode is a project that aims to configure your editor with a language server protocol, performing checks in real time!
35. Emacs LSP mode My contribution was to update an LSP configuration for Crystal (in this case Crystalline) and publish a guide!
36. hackacrow A global tool for testing, comparing the expected output with the output received from a given input, and can be used for any programming language.
37. Chemise Bot A command bot for Twitch (which I use on my streams and some other colleagues also use)!
38. Articles Writing about Crystal
39. Articles Most of the articles published are on DEV (dev.to), in which the example below is the last article written in which I talk about the Crystal ecosystem.
40. Articles I'm currently one of the moderators of the Crystal tag at DEV!
41. What does all this mean? How important is all this?
42. Importance More than talking about my journey, it's talking about how you can also contribute to all of this. The Crystal community in Brazil has grown a lot, so I can say that if you want to start contributing to communities in your region, know that the time is now.
43. Importance Understanding the applicability of Crystal is essential for interactions of any form. The community is what drives projects, therefore, its importance occurs not only at the moment of contribution but at the moment of expansion, use and evangelization.
44. You can make the difference Everyone can contribute
45. Thank you! I hope that you enjoyed!
