Claude Code sometimes ignores web fetch results and wrongly says something doesn’t existβ€”even when the data and logs prove it does.

Ask again more directly and it usually fixes itself, but it’s easy to miss.

GitHub - sassman/docker-sandbox-templates Contribute to sassman/docker-sandbox-templates development by creating an account on GitHub.

Docker just got a lot more useful for AI agents.

Try `docker sandbox` with Claude Code. The only catch: you still have to install your full tooling stack (at least once).

Skip that and use a lightweight, custom sandbox template for Claude Code + Rust:
github.com/sassman/doc...

I usually observe the results before committing and steer deduplication and DRY refactorings on the spot.
But 2 month of agentic mess.. enjoy your day πŸ₯³

oh, which one is it?

I roll now
- stripe
- aws lambda
- the mentioned license forge
- email

nicely done!

I will be there pretty soon too with the JPEG Locker app (jpeg-locker.com)

I might reach out for questions

I have tried on my parallel w11 image and the installation went smooth, no admin stuff required and the app started.
Anything in particular to check?

If you’re building #rust CLIs or TUIs and macos’s idea of where configs should live (~/Library/App... Support/..) drives you up the wall, here’s a fix:

a tiny, zero-dependency, dead-simple alternative to the beloved `dirs` crate

say hi to: dirs-lite
crates.io/crates/dirs...

Just had a genuinely heartfelt joy moment:

Claude Code instrumented the `aws` CLI, set up the policies, and handled all the fiddly bits. Cloud infra has always been an endless source of pain and waitingβ€”but with Claude Code, it’s almost… enjoyable.

Also the maturity for cross platform is not best, but I like zed and their take on some things.
So for me this feels quite right at the moment.

I’ve tried all of them and:
- the whole tauri architecture felt too heavy at some point, also js frameworks are usually too heavy for my taste
- slint keeps the code clean, but I dislike dsl and frontend code compilation (didn’t like Qt either back then)
- GPUI is most compelling, yet quite verbose

This is F5 steganography. Invisible to the eye. And now it has a GUI.

JPEG Locker. Open source. Built in Rust.
Coming soon.

What if images on social media could carry more than what you see?

Not someday. Right now.

I grabbed a JPEG from one of my own tweetsβ€”a regular screenshotβ€”and revealed a hidden message I had embedded inside it.

But that's just the first 30 seconds.
It gets wilder.

I feel you. For larger applications with a lot of complexity (like panels, pop-up windows, etc.) GPUI, not enough and you have to pull in the zed code base anyways, means living on the edge. Or write a lot of components yourself.
There tauri + webframework x is a valid choice to iterate quickly

30.01.2026 07:56 πŸ‘ 1 πŸ” 0 πŸ’¬ 1 πŸ“Œ 0

Writing GUIs in rust, would you rather go

- the GPUI route (zed's UI framework)
- slint ui (custom UI DSL to learn)
- dioxus (add the web/tauri complexity)

Stenography is a long term hobby since University times..

After years of on-and-off effort, it's finally coming together: the art of hiding data in JPEG files!

This Weekend in GitHub PR Lander

Fixing dependabot PRs for breaking change version bumps can be tedious.. That's the perfect job for AI like claude code.

Now directly integrated in the GitHub PR Lander, to save even more time :)

Splitting the plan into phases, where it check which of them can be executed in parallel.

And finally taking care of the execution and verification at the end.

install: via `/plugins`, search for `superpowers` and install
usage: via `/superpowers:brainstorming what todo`

I just experimented with the superpowers skill for claude code.

And it has useful things included that are very verbose and error prone to describe.
Things like validating a plan against actual code and reduce imaginary stuff from a plan or a spec.

Another valuable aspect:

Guess which cool #rust based terminal recorder will land on windows soon?? πŸ₯³

Not sure if only windows 10+ or earlier versions too.
Any beta testers around?

Right now still very experimental, focuses on macOS only (might change)
Leave a comment if a preview of the code is your thing.
