HN Buddy Daily Digest

Sunday, December 28, 2025

Hey buddy, Just caught up on Hacker News from yesterday, Sunday the 28th. Some pretty wild stuff, thought I'd give you the quick rundown.

Photography & Tech Deep Dive

First off, there was this cool article about what an unprocessed photo really looks like straight off the camera sensor. It’s wild how much work cameras do behind the scenes before you even see the picture! People in the comments were debating about how our eyes see color versus how camera sensors pick it up, and how that affects what gets captured. Someone even linked to an interesting article about processing photos from a specific phone, the Librem 5, which was a nice bonus for anyone into that: https://puri.sm/posts/librem-5-photo-processing-tutorial/

China's Secret Nuclear City

Then there was this absolutely fascinating piece about growing up in a secret Chinese nuclear city in the Gobi Desert, nicknamed "404 Not Found." Seriously, like a whole city that was off the maps! The author even jumped into the comments to confirm some details and talk about other people who'd written about it. Sounds like a real eye-opener about a hidden part of history.

HTML-Only Websites?

For us tech nerds, there was a post about replacing JavaScript with just HTML for some basic UI stuff like accordions or menus. The article was basically showing how much you can actually do with pure HTML and CSS these days. But the comments were quick to point out the trade-offs, especially around accessibility and how some things just need JavaScript to work right. Someone even hinted that avoiding JS might be about dodging data collection, which is a thought.

Mac Troubles

Another one that got a lot of traction was "Last Year on My Mac: Look Back in Disbelief." It was basically someone venting about all the problems they've had with their Mac recently. The comments were a mix – some people totally agreed, talking about switching to Linux for their dev machines, while others were pushing back, saying maybe the author's setup was the problem. Sounds like the debate about Mac quality is still going strong!

Dad's Genes & Fitness

Here's a weird science one: A study suggesting that a father's choices, like fitness, might actually be passed down in sperm RNA. So, like, your dad's workout habits could affect you beyond just genetics. The comments got into some deep discussions about epigenetics, and how this kind of theory used to be considered pseudoscience but is now getting more scientific backing. Pretty wild to think about!

Automating CEOs?

There was also this provocative article from 2021 that resurfaced: "CEOs are hugely expensive. Why not automate them?" It sparked a big debate. People in the comments were arguing that a lot of a CEO's job is about "people skills" – motivating thousands of employees, dealing with investors, customers – stuff that's super hard to automate. One person even brought up Elon, saying whatever his skill is, it's repeatable and not just luck. Makes you think about what leadership really is.

The Rise of AI Slop

Finally, a super relevant one: "AI Slop Report: The Global Rise of Low-Quality AI Videos." Basically, YouTube and other platforms are getting flooded with garbage AI-generated content – summaries of books, movies, all that stuff, often without mentioning the original source. People were complaining that it's making it super hard to find good content and that YouTube's always had a "slop problem," but AI is making it way worse. Sounds like our feeds are about to get even messier.

Anyway, that's the gist! Talk soon!
