What do people use to clean up macOS unexpected disk space usage ? Including slack, Chrome, Firefox etc caching
Nowadays any random app believes it can use 10GB for caching to be fast. Well you’re not alone on my machine buddy.

Boy!
Watch for Claude Desktop and Docker sandbox eating your hard drive alive.
I did not understand why my incremental backup was eating 4TB of space in a matter of a couple of weeks. Now I know.

Ah remember also the trick to put a whole in the corner of your blue 720kB disk to boost it to 1,44MB. Good times.
I don't even remember how such tricks were propagated at the time pre internet :D

Running postgreSQL in your JVM in embedded mode 😱

I can see a lot of small and embedded use cases for this as it matures. Good work!

How old are you ?

Sharing your ~/.claude config with Docker Sandbox I wanted to run Claude Code in YOLO mode but isolated from my actual machine. Docker has Docker Sandbox for exactly that: a CLI wrapper and a set of Docker image templates that give you a contained en...

Docker Sandbox is a great idea to isolate your coding agent like Claude Code from your machine. But how to share your settings? I explain it all here emmanuelbernard.com/blog/2026/02...

The good thing about French lunch time length is that you can schedule an OS update and be reasonably confident it will be done.

With us giving more freedom to Claude code and friends. What are your patterns to isolate you « code machine » from your « everything else » machine ?
One container per project and Claude code? A VM? A vps somewhere ?
Go commando?
Something else ? Share and explain 🙏

Towards faster builds Quarkus: Supersonic Subatomic Java

I'm catching up on some Quarkus news and this one caught my eye
quarkus.io/blog/buildin...

It all started from "builds are slow", and the team as usual asked the 5 whys (or more) and reset all expectations to find a proper solution. Proud of this community ❤️.

So you can use your claude subscription (Pro/Max) via copilot and use copilot as the LLM for opencode is that what you mean? Got pointers?

yes! I love opencode, and I love how you can easily write subagents too and call them or swap between plans which are top level agents.
That's how I ended up in my issue with Claude subscription

Anthropic has improved function calling and that’s good If you’ve used function calling in your agentic apps, you know the challenges: Piling up tools consumes a lot of tokens as each tool definition is carried in your context window. Having many too...

Function calling interesting new patterns and their usage in agentic frameworks
emmanuelbernard.com/blog/2026/01...

I did not know but it looks like you cannot have a Claude Subscription and use it with other tolls than Claude Code. I was using OpenCode and now it rejects it. Sad panda.

Note to self, it is 2026 now, not 2025.

Do you use zsh? I recommend you set in your .zshrc the following: setopt NO_BANG_HIST
This will avoid mess around single quote and ! interpretations in your "command line ` strings !".
