last week i remembered that macOS lets you set your own icons and that *I* have the power to delegitimize the professionalism of the software that runs on my machine, so here's a thread of the 16 new icons i've made so far i really forgot how fun it was to just sit down and make art for myself :')

Shipping code that you know will help people. That's the goal. 💙

Neat tip for folks who present a lot: Use the Camouflage extension for VS Code to mask sensitive values. https://marketplace.visualstudio.com/items?itemName=zeybek.camouflage (I usually try to avoid API keys entirely, since Azure supports token-based auth, but I haven't eliminated keys entirely)

Writing LLM evaluation criteria is an art

Convenient!

Visual Studio is going evergreen: - Feature updates every month, not every quarter. - A new annual version each year, released in November alongside the .NET release. devblogs.microsoft.com/visualstudio...

Cool!

We are still looking for feedback on tsgo, but it is worth calling out we expect some type-checking changes that you may need to adapt to. The native previews are easy to grab from npm, and are published nightly to try out! www.npmjs.com/package/@typ...

Need to test the resilience of your .NET Azure Functions? Look no further! Try Dev Proxy, and test your functions without any code changes. Check it out: learn.microsoft.com/microsoft-cl...

Testing .NET app API errors is tough and time-consuming. Dev Proxy, using system proxy settings, intercepts HTTP requests with no code changes. Simulate errors easily, validate handling early, and build robust apps fast. Test it on your next project: learn.microsoft.com/microsoft-cl...

Did you know that you can build your own Dev Proxy plugins? Dev Proxy is versatile and caters to many scenarios. But if you find something that it doesn't support, you can fix it yourself. With just a couple of lines of code, add the missing functionality for you and your colleagues!

An unleaked Windows 2000 beta had a hidden behavior where if you created a certain registry item, set the date back to Oct 12, 1997 and then restart, it would apply a hidden color scheme and place an ominous text file simply titled "gomen" the next time you log in.

Hey Windows Terminal fans! We've been playing around with Terminal Chat in the Canary builds and we'd love your feedback 😊 Have you tried Terminal Chat? Do you find having GitHub Copilot in a pane in Terminal useful? Are there other features you want to see here? Let us know!

This is invaluable! The other day I used it to understand throttling behavior on Azure OpenAI. Combined with the OpenAITelemetry plugin it let me spot inefficiencies and fix them! If you're working with LLMs, you must try this combo.

Testing APIs is noisy when filtering only by URL-irrelevant requests slow you down and hide integration issues. Dev Proxy lets you filter by specific headers and values for focused debugging. Get cleaner logs, diagnose faster, and ship better apps. Check it out: learn.microsoft.com/microsoft-cl...

CSS is getting support for functions, so I made a small utility library for useful things. It's also a copy-pasteable reference. WIP. github.com/sindresorhus...

If you create a Codespace from a PR that was started by the GitHub Copilot agent, the clone of the git repo/branch that will be in the codespace will be a *shallow* clone which makes it difficult to rebase/merge against the branch. You can fix this by running `git fetch --unshallow`.
