Opencode `/share` command copies your session online and give a public URL to share.
Actually useful when writing a blog post and you want to share how you prompted.
Maybe too much details (watch out for sharing sensitive information) and not as structured as I would like it to be but still.

Teams collaborate constantly, but not always for the right reasons. That’s why coordination feels heavy.
Interaction modes help teams choose the right way to work:
🔹 Collaboration for discovery
🔹 X-as-a-Service
🔹 Facilitation
When intent matches interaction, friction falls.

One nice find: if you have subscriptions to both Claude Code Pro/Max and ChatGPT Plus/Pro you use Anthropic and Codex models in Opencode benefitting from their daily and weekly limit plans.

I've been experimenting with AI-assisted development where most of the code is actually written. However, describing this as 'vibe coding' did not sit well with me.
CHOP, "Chat-oriented programming": LLM-assisted programming that is almost the polar opposite of "Vibe Coding".

While I was reading I kept thinking, isn’t this like Rust’s borrow checker and indeed: “Given the foundation provided by the capture checker, the Scala team is now working on using it to implement separation checking. This will allow tracking the use of mutable values and the aliasing of references”
Safe resource usage is coming to #Scala!

Fun and worth to give it a try. Works well.
But it feels too easy to add new features. Found my self vibing a little too much to my own liking.
