I don't understand if it's worth getting the MacBook M5 Pro/Max. I still have my Apple M1 Max 10‑Core CPU, 32‑Core GPU, 16‑Core Neural Engine (whatever this means exactly) 32GB memory It costs at least 3k to reach the same performance, and 4k to be slightly above?

I need a browser that has a similar split-screen behaviour like VS Code: 2 independent tab lists. Anything out there?

As per @steipete.me recommendation, I replaced Google with Kagi (paying $10/m) while already using Perplexity for AI-searches. Just being able to raise, lower and pin hosts is such a big quality of life upgrade.

Using Linear has been such a pleasant experience so far, so many little delightful interactions. Something that's hardly felt in most software nowadays.

Google auto opted in *every* paying Google Workspace user to Gemini. Also adding a nice increase in price, even though no one opted into it. You cannot turn off / opt out. Except... if you open a support ticket. Only then does Google enable the setting to turn it off! I did:

I remember when I first joined Twitter, I told my manager I didn't like my chair (turns out, it was a Herman Miller) I was used to the good stuff: IKEA Markus Chair & Chefsessel Regina. Been happily using this 169 EUR chair for the last 5 years now. Worth trying to switch?

Is there any way to have better video-call experiences on the Mac, for Google Meet and alike? Thinking about global shortcut to unmute, floating video over other apps, and in general a better UX that's more embedded into the OS.

We just launched React Native support. Just 2 lines of code. Maybe we can simplify it even further, the free Context Insights may not need any license key 🤔

I really want to give Firefox a fair chance, but they do all kinds of funky stuff around hijacking text editing behaviour, and using custom dropdowns instead of using the system UI elements.
