Screenshot of the tickets showing 30 seats left for the Early Bird (62.76$ CAD with taxes). Regular tickets will be available on June 7 at 81.13$ CAD (with taxes).
Slack discussion at work. Greg asks: "Any objection to a prod deploy?". Nicolas responds with a gif of Aragorn saying "You have my sword". Miguel chains with a gif of Legolas saying "And my bow". Diego completes with a gif of Gimly saying "And my axe!"
Git diff showing +897 and -4076 lines of code, as a result of configuring Knip on a codebase I'm working with and cleaning up dead code.
Screen recording showing a graph of tasks. We select a task that has a parent task A and a child task B. Press shift + backspace results in that task being deleted with B becoming the direct child of A.
Dr. House leaning in a chair, a coffee in hand, saying "TA DA!" in front of such a simple but useful code snippet
Demo of moving a node to a different parent by pressing "m" to enter "Move mode", then selecting a different node with the keyboard, finally pressing "Enter" to validate.
Right-click on a task will show up a modal with Move up/down options
Demo of re-ordering sibling tasks by moving node up/down with Alt+↑/↓
Amelia Brand (Interstellar) saying "Time is relative, okay?"
Dans le contexte d'une conférence, "Speakers" est traduit par "Haut-parleurs" au lieu de "Orateurs"
Demo of the "Extract to Instance Property" refactoring. It converts a variable defined in a class method into a property of that class, with proper initialization.
A longer recording of transforming various comments into JSDoc ones, with keyboard shortcut (Alt+Enter, then Enter)
A demo of the transformation. You can see a 2-lines JS comment in VS Code. A lightbulb appears on the left. I click on it and there's "Convert to JSDoc comment" available. I select it and the comment turns into a properly formatted JSDoc comment. You can see the JSDoc applies to the property and shows up in VS Code code preview.

A movie poster that parodies "Ghostbusters" but it says "Slopbusters". Headlines are: "Who ya gonna trust?" and "They ain't afraid of no AI"

Someone opened an issue on my "md-to-slack" GitHub repository to say thank you. The issue title is "Thank you for making this". The issue description says: "This is an insanely useful package, thanks so much!".
Burning house girl meme, with the girl asking "Is there a seahorse emoji" and ChatGPT burning in the background, desperately trying to come up with one
ChatGPT is convinced there is a seahorse emoji and starts melting down, trying to write it down.

A proud Nicolas holding a physical copy of his book. The book is 200 pages long. Its cover is mostly red and titled "Legacy Code: First Aid Kit" with some bandage, and a subtitle: "14 techniques to quickly and safely rescue a codebase"
Demo of the broken "linked editing" feature in VS Code. If you have a tag like `<div id="test"></div>` and you delete the original `div` name, the closing tag is being updated. But while you type the new name, the closing tag does not update, and the result is broken. There are other cases of desync between the opening and closing tags.
Hard copy of my book "Legacy Code: First Aid Kit"
Screen capture of running the codemod. I first type `npx zod-v3-to-v4` in my terminal. The CLI asks me where my tsconfig file is. The default value is `tsconfig.json` which is correct. It then takes a few seconds to migrate the 220 files. Finally, it says I'm all set.
I'm holding a printed copy of my book "Legacy Code: First Aid Kit"
Demo of "Extract Parameter" refactoring in VS Code. Put the cursor on a variable declaration, trigger the refactoring and the code is transformed so the variable is moved as a parameter of the function.
My wife, son, daughter, and I are sitting, watching over the mountains in the background. The sky is blue, the grass is green, life is good.
The main stage of Alpes Craft, with people getting seated
A picture with all the participants, speakers and organizers left at the end of the conference. I'm here, right behind the "H" of JS Heroes 😄
Meme of "You guys are getting paid?" but saying "You guys are using versions?"
Laurent shows Haskell types that express what are valid cards in a game. So a Card is the product of CardValue and Suit, but a PokerCard allows the JokerCard on top.
Arnaud talking about that quote
Arnaud slide presenting "t-shape" skills of different developers overlapping to form an overall highly-skilled team on the full stack
Arnaud sur la scène de l'amphithéâtre
Un nuage de mots incluant: no estimate, code review, clean code, pair programming, pragmatism, refactoring, continuous improvement...
L'amphithéâtre qui se remplit petit à petit avec le logo de Alpes Craft projeté dans le fond
Meme from Pirates of the Caribbean in which the officer says: "You have, without a doubt, the worst SEO I have ever seen". To which Jack Sparrow responds: "But you've found my website"
Google search "what color is the moon" that shows results with a large "AI Answer" block at the top. May be helpful, but sometimes not what you want or hallucinates.
