I thought I did something smart by sharing cargo target dir across all projects, but I didn’t: “Your local builds were slow because ~/.zshrc exports one global CARGO_TARGET_DIR shared across every repo. Over time its debug/deps/ accreted 1,291,847 files (318 GB). Every rustc -L lookup and every linker invocation drags through that 1.29M-entry directory, so a 27-second build balloons to ~21 minutes — concentrated in the link phase.”

@CodenameTim You're welcome to do this with Django-auth-ADFS if you'd like!:)

Are you a #python package maintainer and looking for funding? Read the Docs allows you to collect funds via EthicalAds. And now if you'd like, you can route that directly to the #Django Software Foundation better-simple.com/django/2026/05…

@steipete release.bar/jonasks Fun to try! Not sure if I completely agree with the “trust” algorithm though 😅

I always wanted a GitHub dashboard: See my repos, open Issues/PRs, what version I released last, how many commits since last release. So I built one for everyone. release.bar/steipete

@dsp_ Awesome work! Now let’s hope Anthropic actually implements SEP-414 in their products.. Would make life so much easier.

The release candidate for MCP 2026-07-28 is out. The protocol is now stateless: no handshake, no session id, any request can hit any server instance. Plus extensions as first-class (MCP Apps, Tasks), auth hardening, and a proper deprecation policy so we don't have to do this again. blog.modelcontextprotocol.io/posts/2026-07-…

@samuelcolvin @gvanrossum Ohhh wish I was there! Enjoy!!

Come listen to me talk about Pydantic Monty. THIS WILL NOT BE A PRODUCT DEMO. 👀 @gvanrossum

I suspect I'll have a long weekend of reviews ahead of me..

Did Claude Code do something to their default dark theme diff colors lately? So hard to read this _very_ light green on grey text.

@mitsuhiko I agree, so impressive! There's a lot of skepticism, but I'm excited to see where it takes us. "It passes Bun's pre-existing test suite on all platforms" is a pretty good real life test for /goal

Say what you want: this is impressive. github.com/oven-sh/bun/pu…

How do people test their MCP apps locally? Claude + self-signed certificates is a hassle.

@badlogicgames I get so many of these too.. And it’s kind of shocking how many of them have VC funding.

tired

⎿  Retrying in 5s · attempt 5/10 Is Claude Code down again? Nothing at status.claude.com

I wonder how many times Claude have written this lately: `⏺ GH API hiccupped (504). `..

@emilwidlund @polar_sh Looks amazing!

Early glimpse of the new @polar_sh brand. Its visual world is constructed from 3 references held in tension. Mathematical precision. Magnetism. Polar coordinates. Together these create a world that is systematic and generative. Not styled, but derived. Sharing more soon.

@claudeai @_catwu @bcherny I appreciate that Claude Code has MCP session IDs for each session, but unfortunately these don't survive reconnects. Enterprises need this for policy enforcement and monitoring.

It's frustrating that @claudeai can't follow the MCP specc. @_catwu , please do like OpenAI and send a unique identifier for each chat to the MCP servers. SEP-414 is obviously the best, but OpenAI's `x-openai-session` in `_meta` approach is fine too.

@claudeai @_catwu Since Claude Desktop share MCP session ID for all chats, it's not usable for anything. github.com/anthropics/cla…

@tomhacks @GoogleCloudTech I liked portless until I had to work with all the IDPs.. The --tld hack isn't consistent between providers, so I ended up creating github.com/JonasKs/portmap.

Yo @GoogleCloudTech - have you heard of portless from Vercel? How am I supposed to set this?

Since I no longer have my beloved RustRover for reviewing PRs (as a neovim user).. What do people use? GitHub UI is useless. I don't really like the experience in Zed.

@RhysSullivan I loved the thought of portless, but it's unfortunately not a great tool when you deal with oauth flows and redirect URIs. github.com/JonasKs/portmap is my alternative.

made a PR to portless to enable multiple apps to all work on localhost:3000 at the same time feels magical, solves the issue i have with auth all being on different redirect urls
