I’ve revived my Apple II Agent project from January: An Apple IIe with an Ethernet card and a custom client It links to Claude through a Mac proxy and allows conversational Apple II software creation similar to Claude Code When it’s done, it loads the new program into memory

Speaking of security, we created a registry for building OIDC configuration components. Pick your providers, form and validation libraries, and token verifier (powered by jose). Then run one command to copy everything into your app. I've built these a few times before. I know how annoying they can be to get right. Hope this helps. ui.shadcn.com/oidc
It's time to retire long-lived static credentials. We surveyed 1,000+ SaaS vendors and found only 8.4% support secure auth. This is our call to action and how we're doing our part. vercel.com/blog/death-to-lon…

Durability, multitenancy, tool environment control, that's where most harnesses fall apart. Not Pi. Love the harness engineering behind this one.
We have huge respect for the engineering at Vercel and are excited they are building with Pi-Durable

we did invent it and it's called OIDC federation vercel and github actions do it: - each deploy gets a short-lived signed token - AWS/npm/other services verify it via trust policy - you get temporary creds no keys to paste the problem is not enough APIs and services accept it
to me it was always bonkers insane that in order to connect service A with service B i need to ... paste an api key ??? how come as a fucking industry we didnt invent a better way to connect deployments with services

My favorite part about working on this was getting the chance to highlight AI Gateway’s best in class session affinity infrastructure. It handles things like tracking cache state for multiple models within a session, automatic fingerprinting, and much more. Cache hit rates can make or break inference economics, and AI Gateway helps you maximize them right out of the box. Any model, any provider.
This is so cool. One unified view of all your agent sessions. Across personal & coding agents, apps, API keys. Vercel AI Gateway helps you run your business better. You own the model choice, your data (ZDR), and crucially the *meta*data to understand RoI.

Coding CLIs keep getting more complicated. Daemons, 3 layers of TUIs, client-server architectures. The whole point of a CLI is to deliver intelligence with zero friction, and be unix-like. 💾 Try fx.sh. It's 6mb, starts in milliseconds, model-agnostic. It's tastefully minimal: MCP, Skills, Subagents and ACP built-in.

This is the most ambitious puzzle games ever built. It took 10 years to make. It's size is staggering and every puzzle is a gem that has been polished by some of the best designers alive. It's the Manhattan Project of block pushing games. store.steampowered.com/app/4…
