HN Buddy Daily Digest

Saturday, September 13, 2025

Hey buddy,

Just wanted to give you a quick rundown on some of the wild stuff that popped up on Hacker News this Saturday. Grab a coffee, this is a quick one.

Crazy AI Product Generator

First up, there was this insane "Show HN" project: a store that generates products from anything you type in search. Seriously, you type something, and it just makes up a product with a description and everything. People in the comments were cracking up, posting links to stuff like a "Tentative Manipulator" or a "DIY Iridectomy Kit." Someone even compared it to the old Pet Rock, but funnier because these don't actually exist. It's pretty wild what AI can come up with!

Hobby OS Built from Scratch

Then there’s this super impressive project called SkiftOS. Some dude built an entire operating system from scratch using C/C++ that runs on ARM, x86, AND RISC-V. Talk about a hobby! What was interesting in the comments though, was one person saying they actually stopped using AI coding assistants like Copilot because it felt too distracting and honestly, took the fun out of coding for them. Pretty strong take, right?

Heart Attacks Might Be Infectious?

This one's a bit of a mind-bender: new research suggests myocardial infarction (heart attacks) might actually be an infectious disease. Not just from bad diet or lack of exercise, but potentially bacteria! The comments pointed out that it's not totally new territory – links between bacteria and heart disease have been studied before – but this research is pushing that understanding further, especially around oral bacteria. Kinda makes you think twice about flossing, eh?

Geohot on AI Coding

Remember George Hotz, Geohot? He wrote a blog post called "AI coding," basically talking about how AI is changing how we write code. The interesting part in the comments was when someone said the best software engineers they've ever worked with were characterized by "absolute laziness." Sounds weird, but they meant laziness in a good way – like, finding the most efficient, least effort way to solve a problem. Made me chuckle.

Japan's Centenarian Boom

Crazy stat from Japan: they just hit a record with nearly 100,000 people aged over 100! That's a huge number. People in the comments were discussing what contributes to it, like diet and lifestyle, though some were wary of over-sensationalizing Japan's cultural aspects. Still, imagine living that long!

Social Media Fatigue is Real

There was an article titled "Social media promised connection, but it has delivered exhaustion." Preach! It's super relatable. The comments talked about how different early social media was. Someone pointed out that Facebook originally had no business accounts, no ads, no news feeds – it was just about connecting with people. Big difference from the exhausting feeds we have now, right?

Google's AI Trainers Feeling the Squeeze

Finally, a bit of a downer, but important. A Guardian article revealed that the humans training Google's Gemini AI are feeling overworked and underpaid. It highlights the less glamorous side of the AI boom. One comment really stood out: a web developer said they were leaving tech to join a pipefitters union because it offered better life insurance, health insurance, and pay. That's a pretty telling sign about the state of some tech jobs right now.

Alright, that's the quick download. Let me know what you think!
