In the logs I see no indication that trusted publishing is being used. However, I do see that provenance is published. You use a third party tool that hides details.

GitHub Actions is the publisher. This is visible in the npm website search results as well as the `npm search` command: www.npmjs.com/search?q=est...

What would it look like if we allow MDX in props? That means it’s no longer JavaScript. What if we then use curly brackets to allow expressions? That deviates further from JSX. It also conflicts with JavaScript object notation.
<div children={ <span> **strong text** </span> } /> {/* If we allowed this… */} <div children={ { <span> **strong text** </span> } } /> {/* … this would no longer work */} <div children={{ color: 'red' }} /> {/* So this would be the alternative */} <div children={{{ color: 'red' }}} />

MDX needs to balance JavaScript and markdown syntax. Every choice has pros and cons. At the AST level, MDX elements may have mdast content as children. Its props are ESTree, same as for example expression statements. This offers a nice way to escape MDX syntax.

I believe that’s a macOS thing. Here’s the same on my Linux machine.
$ cat test.mjs const startTime = performance.now() process.title = 'node (example)' const endTime = performance.now() console.log((endTime - startTime).toFixed(2), 'ms') $ node test.mjs 0.01 ms

It’s really cool to be working on variable font sizes, improved line wrapping, and RTL support in Monaco editor / @vscode.dev. Also fun to learn about RTL and learn how it fits in this mostly LTR world.

It’s the same, except I use Linux.

I’m a bit confused about this RSC detail. This component renders fine, but the server responds with an internal server error. Does this means the components marked with 'use client' are allowed to use the DOM, but not the module?
'use client' import { useEffect } from 'react' console.log('module', document) export function Test() { console.log('render', document) useEffect(() => { console.log('useEffect', document) }, []) return `Test ${document}` } GET http://localhost:3000/test 500 (Internal Server Error) module #document (http://localhost:3000/test) render #document (http://localhost:3000/test) render #document (http://localhost:3000/test) useEffect #document (http://localhost:3000/test)

This is true, but it is possible to generate invalid DOM structured dynamically. So it may be possible to nest a <form> inside a <p> tag when using frameworks, or simply by using document.createElement().

In case you’re wondering, this did the trick!
The issue you are seeing is a known bug that often occurs when a user account that mentioned you in a thread has been flagged for potentially violating our Terms of Service. When this happens, the content is hidden from view, including the notification, to protect the privacy of the user account and prevent further violations. Our engineering team is aware of this issue, and they are actively working to address it. We apologize for any confusion or frustration this may have caused In the meantime, there is a workaround you can try. You can mark all notifications as read using our Notifications API. To do so, please run the following command, replacing $TOKEN with your personal access token. Note that the token needs to have notifications scope checked. curl -X PUT -H "Accept: application/vnd.github.v3+json" -H "Authorization: token $TOKEN" https://api.github.com/notifications Or if you're using GitHub CLI: gh api --method PUT -H "Accept: application/vnd.github.v3+json" /notifications Please note that this workaround will not remove the repository from the list of repositories you have received notifications for, which appears on the left panel of the notifications page. Unfortunately, it is currently not possible to edit that list. That said, over time, the ones currently displayed will move down the list and eventually won't be visible.

I usually have two panes open in VSCode. So I can watch the code and preview side-by-side.

My OSS contributions have dwindled this year, but I’ll be more active again next year!

Cool to see MDX is now recognized as a language!

I like certain things esthetically (but not everything).

It’s also nice that it’s closer to JS. Also it’s nice that the type information is somewhat preserved in the compiled output.

But TS syntax has some advantages too. For example to annotate typedefs with JSDoc tags and non-null assertions.
/** * Greet a person. * * @param {string} name * Whom to greet * @returns {undefined} */ export function hello(name) { console.log('Hello', name) } /** * Greet a person. * * @param name * Whom to greet */ export function hello(name: string): undefined { console.log('Hello', name) }

Works great on GitHub, but not as nice on GitLab. They require the format below, which works, but doesn’t look as nice as a handle.

Also the link they generate works, but maybe it should redirect to the link using the handle? bsky.app/profile/did:...
