HN Buddy Daily Digest

Sunday, September 7, 2025

Hey buddy,

Just wanted to give you a quick rundown on some interesting stuff from Hacker News today, Sunday. Pretty wild day for tech news!

Windows XP Portfolio

First up, this guy recreated Windows XP as his portfolio website. Yeah, like, the whole desktop experience. It's super nostalgic, you gotta check it out: mitchivin.com. But the comments were kinda mixed. Some people thought it was a brilliant throwback, but others were like, "dude, if you're a graphic designer, this might actually be a bit tone-deaf for a modern portfolio." And a lot of folks really didn't like his AI-generated profile picture – apparently, that's a quick way to get people to shut down your site for some.

MacBook Hinge Sensor

Then there was this cool little tidbit: turns out, your MacBook has a sensor that knows the exact angle of the screen hinge. Who knew, right? The most interesting part from the comments was someone pointing out it's actually a security feature – it physically disconnects the microphone when the lid is closed. Pretty clever way to ensure privacy.

Serverless Horrors

This one's a bit of a cautionary tale: a site called Serverless Horrors is collecting stories about people getting slammed with huge, unexpected bills from serverless services, often due to abuse or runaway usage. The comments were full of people begging for cloud providers to offer simple cost caps, like a circuit breaker for your electricity bill. It sounds like a real pain point for a lot of developers messing around with cloud stuff.

AI Modernizing Old Code

Speaking of AI, someone used Claude Code to modernize a 25-year-old kernel driver. That's pretty wild, right? Imagine just feeding old code to an AI and having it update it! Comments noted that while it's powerful, it's still super hard when there's zero documentation or for those tiny, tricky optimizations that AI can struggle with. It's not a magic bullet yet.

Dermatologist's "Vibe Coded" App

This was pretty neat: a dermatologist actually "vibe coded" (which apparently means used AI to code) a skin cancer learning app: molecheck.info. How cool is it that non-developers are now building apps? Some people in the comments were super excited about this lowering the barrier to entry, but others weren't too keen on the "vibe coding" name, thinking it sounded a bit unserious for something so powerful.

Windows 11 AI Bypass Tool

And for those not loving all the new AI stuff, there's now an unofficial tool to bypass Windows 11 requirements and disable all the AI features. Sounds like a lot of people just want a clean, no-frills OS without all the extra AI bloat Microsoft is pushing. Gives users more control, which is always a good thing.

Bye-Bye Intel, Hello AMD

Finally, a relatable one for anyone into building PCs: one guy wrote a detailed post about giving up on Intel after years and switching to an AMD Ryzen 9950X3D. He was looking for stability, and a bunch of comments chimed in with similar experiences, sharing tips and frustrations about tuning AMD systems for optimal performance and power usage. Sounds like the CPU wars are still going strong!

Anyway, that's the gist of it. Talk soon!
