Trying Ubuntu in Hyper-V once again and the experience is not great. The clipboard randomly stops working, I have to close and reopen the session.

So it turns out GitHub Copilot in VSCode is much better at doing code search on a very large code base because it could benefit from automatic remote indexing from GitHub, where Claude Code is basically just grepping files locally with no auto indexing: code.visualstudio.com/docs/copilot...

New blog post! 📰 I tried "vibe coding" in VSCode using GitHub Copilot (Claude Sonnet) to build an MCP proxy tool in Rust — I didn't touch a line of code, just pure agent mode magic 🧙‍♂️ 🚀👇 awakecoding.com/posts/vibe-c...

I was stuck in a freezing cell without explanation despite eventually having lawyers and media attention. Yet, compared with others, I was lucky

Lots of interesting insights in this thread
Her post made some banger points about middle managers which I will not recap; go read it.

But it also left me wondering...so, is cutting management ALWAYS bad and a danger to your future??

Obviously not. You can have too much management or not enough management.

How can you tell the difference?!

Cancelled Youtube Music (switched to Tidal), Netflix, Disney+ and Microsoft Game Pass. My money will go anywhere but the US whenever I can until this nonsense ends. I have nothing against Americans but Trump can go fuck himself.

This is completely insane. What the 6 minutes video to get a sense of the scale of the work involved to get this running. Huge props to @michigantypescript.com .
All told, it's been a year and a half of hard work to get to today. We've got so much to share about this project. Let us know what you'd like to hear about! :)

I have a new paper in Dialogues on Climate Change exploring climate outcomes under current policies. I find that we are likely headed toward 2.7C by 2100 (with uncertainties from 1.9C to 3.7C), and that high end emissions scenarios have become much less likely.

I (finally) wrote up my thoughts on "Founder Mode" and the Brian Chesky morality tale about how he turned around Airbnb company culture.

This has made it into the Silicon Valley water table; it must be dealt with. There are some good nuggets within; let's dig them out.

Good read of @ericlaw.bsky.social's mistakes building Fiddler as a side-project while working at Microsoft.

Super tempted to deep dive into that Thread Pool problem he hints at towards the start, something Visual Studio itself thinks about a lot!

Note mostly for future me; if github.dev displays "Unable to resolve resource vscode-vfs" when opening a repo, disable Enhanced Tracking Protection in Firefox.
