Syntax Highlighting
Wrap your code sample in ```triple backticks``` to render a code format block:
0.1 + 0.2 // 0.30000000000000004
NaN === NaN // false
typeof null // "object"
\[] == !\[] // true
"5" + 3 // "53"See it here https://mu.social/profile/flo-bit.dev/post/3mogi56vfec27
Tangled Strings
Strings on Tangled is a minimal lightweight pastebin-style feature integrated into user profiles for sharing configurations, logs, or short code blocks.
Here's an example of a string by @flo-bit.dev : https://tangled.org/strings/flo-bit.dev/3mnz3howjai22.
Add this string to your Mu post and it renders like this:

Work In Progress
Choose the content service that supplies user profiles, posts, and feeds to Mu.
- Only use a content service you trust.
- Different services may return different content and apply different moderation policies.
- Not every content service supports every feature in Mu. If the service you choose does not support a feature, Mu may still use Bluesky to provide it.

Choose which service the Translate button uses. DeepL and LibreTranslate are privacy-friendly alternatives to Google.
Go to → https://mu.social/settings/language
Copy your mu.social data from one content service to another.
Choose where to copy from and to, then select the data you want to transfer.
- This is a one-time copy, not a sync. Changes you make later won't be transferred automatically, and your active content service won't change.
- Some data, including drafts and certain mute settings, can't currently be transferred.

Mu's Newsrooms feature groups journalists together with their publication, so instead of following individual accounts one by one, you can follow an entire outlet (like 404 Media) and see its staff listed alongside it for quick-follow. Newsroom saves you digging around Bluesky trying to find who writes for where.
