running typescript and restart on changes in Node without any extra deps

Hoping this is faster and better than playwright mcp

this is why you think open source models aren't good on the left is the average provider, on the right is opencode zen left is slow, vomits out tool call parse failures, confuses itself and takes 5x longer to complete

The goal for your X timeline is to get out of the mainstream algo and the political crusades and find your niche. You should be able to post about your interests and have friendly, relevant people chime in. If you’re seeing gas station fight videos, your account is not ramped…

i've spent the last six months building the most insane thing in my career: a new PostHog website. and in about 12 hours, i'm going to push it live. but it's not just a redesign - it's like an operating system in the browser. the level of detail is insane. no normal company…

Before Bun, you had to tradeoff easy to write (JavaScript & TypeScript) vs performance (Rust, .NET, Go, etc) That tradeoff no longer exists

Was thinking of a .net 9 backend, but @bunjavascript is just stupid good I know local benches are meh, so grain of salt obviously .NET 9 (NAOT): 21.5k RPS (p99 6.2 ms) Bun.serve: 31.5k RPS (p99 3.1ms) Axum (Rust): 20k RPS (p99 0.9ms) Rust has best tail (expected) but... bun

if I sense a competitor I immediately switch to my alt accounts and request Windows support or an Android version or complain about bugs on Arc or Brave or ask about localized pricing

Damn it worked! Genie 3 world --> inpaint UI --> 4x topaz AI upscale --> train 3d gaussian splat You can step inside a painting of Socrates from 1787. Better than any image-to-3d model I've seen. I think Google has stumbled upon the killer app for VR -- the literal holodeck.
