CJ just one-shotted a 15 min rant and it's incredibly refreshing.

I heard a rumour that they're releasing HTML6 next week, which deprecates semantics and introduces 3 new types of div.

Can't wait!

@mattpocock.com Do I need to include fields that are "never" in discriminated unions? ChatGPT keep telling me the second one is "safer" but I don't believe it.
A TypeScript code snippet showing two type aliases for defining asynchronous data states. The first type, `State<T>`, is a concise discriminated union with four possible states: - `{ status: "loading" }` - `{ status: "idle" }` - `{ status: "done", data: T }` - `{ status: "error", error: Error }` The second type, `StateVerbose<T>`, shows a more explicit version of the same states, using the `never` type for properties that shouldn't exist in a particular state. For example, in the "loading" state, `data` and `error` are explicitly marked as `never`.

Decided to challenge myself and solve @cassidoo.co interview question of the week using types only. It's possible 🤯

This challenge got me so hyped, it was the perfect excuse to write a blog post!

A screenshot of TypeScript code implementing a recursive conditional type called ValidSequence. It validates a readonly array of colors against a union type ValidPairs. The logic recursively checks if each adjacent pair in the input array is present in ValidPairs. Test cases in the image demonstrate its validation for both valid and invalid sequences.

Is it crazy to use prefixes for global css classes when using scoped style (vue and svelte)?
- Easier to know where the style is coming from
- Harder to get conflicts
- 0 specificity with :where make it super easy to override it

@w3cj.com & @tolin.ski were talking about hard to find global styles.
Image is a print of the following CSS Code: ``` :where(.g-card) { display: flex; flex-direction: column; justify-content: center; align-items: center; padding: 1rem; border-radius: 0.5rem; box-shadow: 0 0 1rem rgba(0, 0, 0, 0.1); background-color: #fff; } ```

Zero novo, mas fica a recomendação.
Sim, ele tem 1h41min. E, sim, vale a pena.
Uma reflexão incrível sobre "gênios" infantilizados e "mulheres manipuladoras".

Elon Musk plans to spend election night with Donald Trump, giving the former president direct access to the person controlling X, a key information platform, on what could be a chaotic evening.
Musk to Spend Election Night With Trump at Mar-a-Lago
Elon Musk has spent $119 million on a super PAC supporting Donald Trump and held events on his behalf. But his ownership of X is especially valuable.

Copilot reviewer is calling attention to the fetch call without `await`. It suggest adding the `await` keyword, but that means it has to include `async` to the `useEffect` callback, which I don't think is best practices for React.

I'm not a React dev tho, am I wrong?

GitHub Copilot code review highlights an unawaited fetch call in a JavaScript file. It suggests using await to prevent unexpected behavior. The call is inside an useEffect call back

One of the coolest things about being middle aged is that (assuming things go reasonably well, statistically speaking) I have my whole life ahead of me! And this time around I actually know stuff and can do things right from the start and I have way more resources. It’s kind of awesome, honestly!
