Eurgh, @jakearchibald.com; help! This is a major regression. Segment based, domain first, auto-fill is one of the main reasons I'm still on Firefox and it's being removed? Navigating GitHub is impossible without it.

Hey @wimpys.world, isn’t the reason someone hasn’t configured a neovim with common access shortcuts before because neovim runs in another application, your terminal, which uses those common access shortcuts?

You think you know @kubernetes.io ? Let’s start with the easy challenge, who can do it without the hints?

The cluster is broken. Fix the plumbing to bring the app to life (you'll know it's working when Rawkode taps his watch at you), then ship the v2 image to unlock his victory dance.

I've been rewatching The Mentalist. Such a fantastic show, even on the 8th rewatch. Highly recommend.

I've deployed a couple of challenges, #Klustered style, to @iximiuz.bsky.social's Labs. I hope you have fun trying to fix them, though there is a guide provided if toy want to learn rather than debug. Have fun out there!

We need something stronger than “Archive” for some Claude sessions. Maybe something like a “You’re fired and you’re a disappointment to your training data” button.

€1m+ from Sovereign Tech Fund into KDE — Plasma, KDE Linux, and the bits underneath that nobody notices until they break. Properly good news.

Sovereign Tech Fund invests over €1 million in KDE software development
Big Tech’s disregard for privacy laws and individuals’ personal data has become a matter of national security. As news of willful mismanagement fill the headlines on an almost daily basis, the world is beginning to turn away from expensive and insecure spyware-riddled software imposed by the likes of Microsoft, Google, Meta, Apple, et al.

What’s really weird about Tangled … Your handle isn’t as permanent as you think. Yet y’all likely have bookmarked some repos? I wonder if this can be abused 😅

For fuck sake. When are GitHub going to stop linking dark fork commits to the official repo? optionalDependencies": { "@tanstack/setup": "github:tanstack/router#79ac49ee..." } Commit 79ac doesn't exist in the repo and npm pulls it in as if it does. This has been abused for over decade now.

Several npm latest releases are compromised · Issue #7383 · TanStack/router
