Cool approach.

But, a compromise still lands on host's kernel, Docker doesn't provide kernel isolation (well it does on a macOS because it runs in Docker machine but thats a side effect).

I wonder if a better solution would be to play with seccomp or Linux capabilities so that Chrome is sandboxed even in Docker. Not sure how this would work tbh.

Answering here to get ideas, I saw your fix on Git and request for feedback (will try to review and give it some thought once I find some time)

Neat project, I like the idea. One thing from a quick read: you launch Chrome with --no-sandbox. Is there a good reason for that? Security wise it's probably not a good idea. If there is no reason, I'd suggest leaving the sandbox on!

In any case, cool stuff :)

- "Anyway, possible slight hiccups in the merge window aside, the news today is 7.1." - "nothing particularly interesting or scary stands out, which is as it should be."

So, a number.

Show HN: GitShare – Turn GitHub repos into beautiful social media screenshots

dimiprasakis — Wed, 27 May 2026 13:08:30 +0000

I needed a tool to turn GitHub repos into nice screenshots (for social media) but couldn't find one that I liked. There are plenty for X and LinkedIn posts, but not many for GitHub repositories.

I built a simple static web app (GitShare) where you paste any public repo URL, customize it live and then export as PNG/JPEG/WebP. It runs entirely in your browser (it uses GitHub's API client-side, so you're rate limited to 60 unauthenticated requests per hour).

Tested on Chrome, Firefox, Safari, Brave, and DuckDuckGo on macOS. Fixed tons of bugs, and I think it's reliable now. But if you hit issues on any of those or another browser/OS please let me know, happy to fix them ASAP (and it's open to feature requests and contributions, of course!)

New comment by dimiprasakis in "How Shamir's Secret Sharing Works"

To be honest, I always wondered why variations of SSS haven't been seen commercial adoption more. For example, instead of storing API Keys in GitHub repos, the keys could be constructed on the fly by approvers signing their shares. I guess the UX of coordinating share-holders is what kills most implementations...

SSS does suffer though for some serious weaknesses, i.e. it trusts the shareholders. A cheating party can submit a fake share during reconstruction, corrupting the recovered secret, and honest parties have no way to detect this something that verifiable secret sharing fixes.

Anyway threshold crypto is a very elegant field and the math is there is really beautiful.

What I'd love to see is an e-ink reader, purpose-built for RSS. Think of getting your morning digests from select sources without touching your smartphone or PC. Heaven
