HN Buddy Daily Digest

Sunday, July 13, 2025

Hey buddy, Man, checking out Hacker News from Sunday, July 13, 2025, there was some cool stuff. Let me hit you with the highlights real quick.

Let me pay for Firefox

Okay, first up, this one got a ton of points: people are talking about wanting to pay for Firefox. Like, voluntarily. It's on their own discussion forum. Seems folks just wanna throw money at Mozilla to keep Firefox going strong or maybe get some premium features. The comments were interesting, some people were talking about how tough it is for Firefox going up against Chrome, and one person even had this wild take that if Firefox struggles, it actually helps Google in the long run. Weird, right?

How does a screen work?

There was this article explaining how computer screens actually work. Pretty cool deep dive into pixels and stuff. The comments section had people correcting or adding details, especially about older monitors (CRTs) and how modern ones refresh. If you're ever curious about what's happening inside your display, this looked like a good starting point.

Reading Neuromancer for the first time in 2025

Someone wrote about reading that classic cyberpunk book, *Neuromancer*, right now in 2025, which is kind of when the book is set. Cool timing! People in the comments were chatting about how cyberpunk used to be this niche thing but got totally mainstreamed. They also talked about how the author, William Gibson, is more about creating a whole *feeling* or vibe in his books rather than super technical details. Someone mentioned hoping a new movie or show adaptation gets it right.

OpenCut: The open-source CapCut alternative

Saw this project called OpenCut popping up on GitHub. It's trying to be an open-source version of that video editor CapCut that's super popular, especially with the TikTok/Instagram crowd. The comments pointed out that most people who use CapCut aren't hanging out on GitHub, so getting the word out might be tricky. Someone else mentioned it seems like it's mostly a front-end tying together other existing tools, but hey, an open alternative is always neat.

GLP-1s Are Breaking Life Insurance

This one was kinda wild – apparently, those new weight-loss drugs like Ozempic (called GLP-1s) are messing up the math for life insurance companies. Makes sense, I guess, if people are getting healthier and living longer, the actuaries gotta redo their calculations. The comments had a good back-and-forth about things like muscle loss on these drugs compared to just dieting, and how society views obesity differently than, say, smoking addiction when it comes to health and insurance.

The North Korean fake IT worker problem is ubiquitous

Okay, this was interesting and a bit scary. An article about how fake IT workers from North Korea are apparently getting hired all over the place remotely to make money for the regime. People in the comments were sharing ways companies try to spot them, like asking really specific, weird questions in interviews or even trying to make candidates pick up equipment in person (which obviously flags remote fakes). It just highlights how tricky hiring is these days.

Does showing seconds in the system tray actually use more power?

And finally, a classic tech question: does having the seconds show up on your computer's clock in the corner use more power? This article from LTT Labs actually tested it. Turns out, yeah, maybe a tiny bit, especially if you've got one of those fancy OLED screens or if your computer is just sitting there doing nothing else. The comments had people sharing tips on saving power with dark themes on OLEDs and wishing computers were smart enough to update the clock without waking everything up.

Anyway, that was the cool stuff from Sunday. Talk later!
