Ruby and Rails News 🛤
A lot of Rails news since the last issue:
- Stimulus 3 and the final version of Turbo 7 are out, which means… Hotwire 1.0!
- First alpha release of Rails 7!
That’s too much emotion, let’s go have another coffee. ☕
Ruby Tip 💎
The Splat operatorIn Ruby, we have the possibility to define a method with an unnamed parameter using “ * ”.
This parameter allows to:
- ignore one or many arguments given to a method
- define which arguments won’t be used in the body of a method
- better inheritance and usage of the super method

🐛 There’s a Glitch in the Matrix
We think Yuliia Kuprii’s article makes the world better: we get advice on how to describe a bug to avoid this infinite loop that everybody is afraid of: “The bug is not reproducible locally” <> “It happened again in prod”. And we discovered a word we didn’t know: a heisenbug.

📚 Some Feedback
As you imagine, we love people sharing feedback about their careers in order to grow and learn together (this is one of the reasons why we write this newsletter ❤️). We liked Ademusoyo’s thread and the five keys for career development. And there is a lot to learn from her Instagram feed!

🔵 “Grass is Green, Links are Blue”
No, it’s not about haiku but about a dive in Herstory to understand why the hyperlinks have this blue color. Elise Blanchard shares many old graphic interfaces to find out who decided on this first. It’s interesting to see how some conventions (underlined links, the hover…) have been implemented. Klein or Michel Pastoureau had better watch out!

🎨 The Guide of CSS Art
We often talk about CSS art in the newsletter because we are impressed by all we can do with these tiny pixels. The artist and developer Yosra Emad knows how to make us happy. In her last article, she shares her secrets about creation. Perfect to start today!

⚡ Lighthouse Treemap to analyze the performance
Often when we want to know what is responsible for the bad performance of a website, JavaScript makes a good culprit. In her article, Sia Karamalegos shows us how to use Lighthouse Treemap to not only find the file to look into but also to have the information in color… and big rectangles.

🗄️ How Do You Organize Your Files?
Many computer science and bootcamp teachers say it: new students don’t understand the file tree and how it’s organized. We let you dive into Monica Chin’s article to get some clues explaining this phenomenon.

Hacktoberfest
The Hacktoberfest is an event promoting open source that happens every year in October. It’s not about beer but really about code (even if both are not incompatible 🍻). A lot of events and workshops are organized this month to discover or come back to open source.
