HN Buddy Daily Digest

Monday, January 19, 2026

Hey buddy,

Man, you wouldn't believe what was popping off on Hacker News today. Had some wild stuff, some interesting tech, and of course, the usual political fights. Here's the quick rundown:

Tariffs Are Hitting Americans Hard

First up, the biggest story: a new analysis came out saying those tariffs from 2025? Turns out American importers and consumers are the ones footing the bill. Shocker, right?

People in the comments were pretty fired up. Some were like, "See, I told you economics matters!", while others were questioning the study's bias, since it came from a German group. Classic.

Bluetooth Chat App, No Internet Needed

Then there was this super cool project: a guy built a decentralized peer-to-peer messaging app that just works over Bluetooth. Imagine being able to chat with people nearby even if the internet goes down. Pretty neat, huh?

The comments were debating how practical it is. Someone said they tried scaling similar tech (Meshtastic) for big events like Burning Man, and it gets tricky with thousands of devices. And of course, the usual crowd was worried about governments not allowing untraceable comms. Wild.

Check it out here.

Fairphone Goes Corporate

Big news for ethical tech: Radboud University in the Netherlands is making Fairphone the standard smartphone for all its employees! That's a pretty massive win for repairability and sustainability.

But the comments were a mixed bag. Some were worried about the security, saying the software might not get updates fast enough for a corporate environment. Others were just praising how easy Fairphones are to fix, especially the screens.

See the announcement.

Amazon Ditching Inventory Commingling

Get this: Amazon is finally ending that whole "inventory commingling" thing by March 2026. You know, where they mix up a bunch of different sellers' identical products in the warehouse. This means hopefully less chance of getting a knock-off when you paid for the real deal.

Everyone in the comments seemed to agree this was a good move, especially with all the counterfeit issues. One guy even brought up how 3D printing helps him fix household stuff, which was a bit random but cool.

Details on Twitter.

Big Solar Storm Alert!

So, we had a pretty significant space weather event today, like a Level S4 solar radiation event, which means a G4 geomagnetic storm. Doesn't sound great, but apparently, it's also making the aurora borealis go nuts for people up north!

Folks were discussing how this affects things. Some were saying fiber internet is pretty robust against this stuff, unlike older infrastructure. Others were just stoked about the amazing light shows they're seeing.

NOAA's report.

New AI Model: GLM-4.7-Flash

Another day, another AI model! Someone posted about GLM-4.7-Flash, a new language model that sounds like it's trying to be super efficient and fast.

People in the comments were already benchmarking it against other models like Claude and Mistral. Sounds like it's a solid contender, maybe around Claude Sonnet 4 level, but still not quite hitting the absolute top-tier performance.

Check out the model.

Apple's App Store Ads Getting Sneakier

And finally, Apple being Apple. They're apparently testing a new App Store design that makes ads blend in even more with regular search results. So it's gonna be even harder to tell what's an ad and what's an actual app recommendation.

Unsurprisingly, the comments were ripping into Apple. People are fed up with how bad App Store search already is and feel like Apple's just trying to milk more money out of developers and users.

Read about the design changes.

Anyway, that's the gist of it. Gotta run, talk soon!
