HN Buddy Daily Digest

Friday, June 13, 2025

Hey buddy,

Man, you gotta hear about some of the stuff on Hacker News today. Was scrolling through the feed and saw some interesting things.

Space is Wild

First off, check this out: there was this old article from 2014 about a solar system model where the moon is just one pixel. It's called "If the moon were only 1 pixel: A tediously accurate solar system model (2014)". It just shows you how ridiculously empty space is between planets. One guy in the comments was saying how light speed feels slow when you think about how far away galaxies like Andromeda are. Makes you feel tiny, you know?

HP and Palm Drama

Then there was this juicy business story: "I convinced HP's board to buy Palm and watched them kill it". This guy who was involved wrote about how he pushed HP to buy Palm back in the day, and then watched HP completely mess it up and kill their mobile stuff. People in the comments were talking about how big companies often just have too much internal baggage to do anything cool, and someone else mentioned how Microsoft's Windows Phone also tried hard but failed.

Meta Goes Big on AI

Okay, big tech news: "Meta invests $14.3B in Scale AI to kick-start superintelligence lab". Meta is just throwing a ton of money at this company Scale AI to try and build some super smart AI lab. Kinda crazy money, right? Some folks in the comments were wondering why Meta, being a social network company, even needs to be *that* deep into AI. And get this, someone who claimed to work there said Meta is actually one of the most inefficient companies they've seen.

Paying It Forward

Something a bit different, there was this nice "Ask HN" thread called "Ask HN: How do I give back to people helped me when I was young and had nothing?". The original poster wanted to thank people who helped them out when they were younger and struggling. The most common advice in the comments was to just "pay it forward" – help other young people who are struggling now, rather than trying to make some big gesture to the original helpers. Or just telling the original people how much they helped can mean a lot.

Apple's Glassy Future?

Here's a cool tech speculation: "Apple's Liquid Glass is prep work for AR interfaces, not just a design refresh". The idea is that Apple's new design look might not just be about making things look shiny, but actually getting ready for augmented reality stuff, maybe screens you can see through or interact with in new ways. Someone in the comments remembered how Windows 7 had those translucent windows back in the day.

Anker Recall Heads Up

Okay, practical alert: "Anker is recalling over 1.1M power banks due to fire and burn risks". If you have an Anker power bank, specifically the PowerCore 10K (model A1263), check it out because they're recalling over a million of them because they could catch fire. People in the comments were sharing links to the official recall page and mentioning other Anker recalls too. Definitely worth checking if you have one.

Ageism in Tech? Still a Thing.

Another "Ask HN" thread was about "Ask HN: Is ageism in tech still a problem?". Sounds like the answer is a pretty solid yes from a lot of people in the comments. People were sharing experiences about feeling like older workers are seen as slower or less adaptable, or even a threat to younger managers. One person who was 38 felt tired working at a place where the average age was 27 because of all the drama over small stuff. Rough stuff.

Anyway, just wanted to give you the highlights. Talk soon!
