I’m actually very tired of all the Americans having takings in Ceuta. Both on left and right (or whatever you call your weird ideologies over there) the takes are so off with so little respect of history that I can only conclude you’re all brainwashed to the max.

Really really don't like that Zed downloads random binaries without my consent. They also most of the time don't work due to being dynamically linked.

The problem with OIDC and SSO in general is that it only solves identifying the person but most clients all implement their own session management. This is is why I think an auth proxy is a way better strategy than configuring SSO on all your services as you have centralized session management

The entshitification of GitHub is happening at record pace since they've replaced all their engineers with AI. The website literally is not usable anymore on slightly bad network connections. We need to abandon ship before we're all going down with it

Hey @rmondello.com when I only implement conditional mediation for passkeys on Safari; there doesn't seem to be a button for people to use their Security Keys . In Chrome they do give this option when pressing "Use nearby device". Is this expected? It feels like a bug.

One thing im excited about with these kind of minimal“everything embedded in a UKI” distros like frood, particleos, and Bocaditos, is that you can precompute PCR values during build time and use TPM attestation as your bottom turtle to bootstrap trust in your network

After hunting down obscure heap corruption bugs that only happen when using certain libraries together in production this week I am reminded of the following quote: "Follow these two simple rules to run stable production systems: 1. Never update your system 2. Always keep your system up to date "

Hope it goes better than NixOS. Moving to Discourse was a terrible idea. Works too much like social media and running social media is hard.

Them: We want an accurate SBOM with all the build time dependencies. It has to be *accurate* Me: *Emails 10 megabytes of .drv files* Them: It's too big! How can we deduce anything from this. Me: I'm sorry for using the only package manager that's actually honest about this.

It's not just Norway. Basically all of EU YouTube that didn't cater to a US audience was demonetized, deprioritized and deplatformed out of existence. Mostly due to a clash of cultures. YouTube is simply too prude and doesn't care about anything but English content. www.youtube.com/watch?v=Ehp0...

I wonder what happens if you enable DNS64 on a dual-stack private subnet that also has VPC endpoints for e.g. SSM. My hope is that it will route the traffic over IPv4 to the endpoint and not over Ipv6 NAT64 hitting the NAT Gateway but not sure lol.

Wow GitHub Action's distribution model is "Just bundle your TypeScript to one big js blob and commit it to the repo". Funny part is this makes it so that Dependabot PRs (Also a GitHub product) do not work for Github Action repositories as it doesn't regenerate the dist folder.
