🤣 Australia thinks GitHub is as risky for kids as TikTok
Australia’s eSafety Commissioner is eyeing GitHub as a potential danger zone for kids, alongside big names like TikTok and Instagram. With new age restrictions kicking in December 10th, platforms deemed harmful to users under 16 could face bans. Even GitHub’s dev-friendly features, like comments and sharing, are under scrutiny, as regulators question whether it functions too much like a social network. But the internet’s not having it. "Complete lunacy," one user called the move, blasting the idea of banning kids from learning to code.

🤔 The Secret to Greatness? Track Your Decisions
Your greatest mentor? It might just be you.
Michał Poczwardowski argues that writing down your key decisions, and reflecting on them later, can transform how you think, grow, and lead.

Two key rules:

  1. Document your big decisions while you're making them.

  2. Return to them with fresh eyes to learn from who you were.

⁉️ Questions to ask when you think you need to finish something
Cassidy Williams has a go-to checklist for when old side projects start haunting you. Before pushing through to finish something, she suggests asking yourself: Does this still align with my current goals? Would I even start this again today? Am I doing this for me or just to prove a point? A quick mental audit like this can help you let go of projects that no longer serve you, or reignite the ones that still matter.

🐍 Why Today’s Python Developers Are Embracing Type Hints
Typed Python is having a moment, and for good reason. As Python evolves from a prototyping tool to a production powerhouse in AI and data science, static typing is helping devs catch bugs early, scale codebases faster, and communicate intent more clearly. Thanks to gradual typing (via PEP 484) and tools like Pyrefly, adding type hints is now easier than ever, and your future self will thank you for it.

📉 Programming Deflation
AI is making code cheaper by the day, but what does that mean for developers? Kent Beck explores the paradox: fewer coders may be needed, or demand might explode as software becomes easier to build. In this new era of "programming deflation," real value shifts to understanding, integration, and judgment, the human skills that machines can’t replicate.

👨‍🎨 Free Animation Class: Squash and Stretch Explained
Part of the Whimsical Animations Open House, this free lesson gives a peek into the new (and highly anticipated) course. It explores the classic “Squash and Stretch” principle from Disney animation, showing how even subtle tweaks can make UI elements like arrows feel dynamic and polished.

🎭️ CSS Typed Arithmetic
CSS typed arithmetic is here, and it's quietly revolutionizing layout and animation. With support just starting to land in browsers, this feature lets you do real math between typed values (like dividing pixels by degrees or rems), unlocking dynamic, logic-driven styling once only possible with JavaScript. It’s a major leap toward true computational CSS.

🖼️ React Router RSC Framework Mode Preview
React Router v7.9.2 now offers preview support for React Server Components (RSC) in Framework Mode, powered by a new Vite plugin. While RSC in Data Mode laid the foundation, Framework Mode simplifies setup, bundling in dev-friendly features like typegen and file-based routing. SPA Mode and pre-rendering are coming soon, but you can try it today with a scaffolded starter template.

🤔 The Web’s Most Tolerated Feature
The long-maligned zoom CSS property, once a messy IE hack, has finally earned its redemption arc. After decades of browser inconsistency and developer frustration, it’s now part of a new spec with broad support, thanks to Interop 2025. As Mike Pennisi of Bocoup puts it: it only took 25 years (and a few stacked bar charts) to make the web’s most tolerated feature actually... tolerable.

⬆️ Parallel and recursive route rendering
React Server Component routers flip everything you know about routing. Instead of nested trees that waterfall fetches, RSC routes render in parallel on the server and are stitched together recursively on the client, dramatically improving performance. Ryan Toronto breaks down how Twofold implements this clever pattern, using stacks, placeholders, and recursive components to sidestep the usual rendering bottlenecks.
