Hey buddy,

Man, you gotta check out Hacker News from Sunday. Some pretty interesting stuff popped up. Lemme give you the quick lowdown.

Credit Card Terminal Hack

First off, this dude managed to get a root shell on a credit card terminal! Like, full access. The article goes into how he did it. People in the comments were talking about how crazy that is, especially with payments. Someone mentioned how the security checks on these things might only happen when they first start up, not while they're running. Another guy thought maybe this kind of access is actually built in for maintenance or something, which is kinda wild to think about.

Progressive JSON

Then there was this post about something called "Progressive JSON". It's basically trying to make JSON load faster by sending it in chunks or in a specific order so you can start using the data before the whole file is finished. The comments were quick to point out that this totally breaks how standard JSON parsers work. People brought up existing ways to stream data, like line-delimited JSON (ndjson), and debated if this new approach is even necessary or if just building pages on the server is faster for getting something interactive on screen.

Figma Slides "Disaster"

Oh, and if you use Figma, there was a post titled "Figma Slides Is a Beautiful Disaster". The author was ripping into their new presentation feature. Lots of people in the comments agreed, saying Figma feels like it's more for investors than users these days. They were complaining about how slides are often misused anyway (too much info!) and talking about the pain of presenting with multiple monitors using tools like Keynote vs. Figma. Someone did push back a bit, saying Figma's offline feature *should* work, it just seems broken right now.

Andor's Cinematography

Switching gears, there was a cool article talking about the cinematography of the Star Wars show "Andor". People loved that one. The comments were full of praise for how different and mature the show feels compared to other sci-fi, focusing on politics and real human stuff. Someone pointed out how the showrunners apparently got a rare amount of time to plan things out beforehand, which probably helped make it look so good. It reminded some people of the original Star Wars movies' "lived-in" look.

Samurai Jack's Visuals

Speaking of visuals, an article about the art style of the cartoon "Samurai Jack" was popular. If you ever watched that show, you know it looks super unique. The comments had people comparing it to older cartoons like Thundarr the Barbarian and just generally gushing about how creative and visually stunning it is. One funny comment picked up on a line in the article and joked that "Dragon Ball Z with laser swords" sounds like a billion-dollar idea.

DeepSeek AI Costs

There was also a technical one explaining why this AI model called DeepSeek is cheap for big companies but pricey to run yourself. It's all about how big places can process a ton of requests at once (called "inference batching"). The comments got pretty deep into hardware talk, comparing AMD and Nvidia chips for AI, and mentioning specific software like ROCm. Lots of back and forth on which hardware is catching up or still has issues.

Ukraine Drone Attack

Finally, there was a news story about Ukraine claiming to have destroyed a bunch of military aircraft deep inside Russia with drones. This one had a ton of comments, as you can imagine. People were debating how reliable the claims are (from both sides, really) and whether this kind of attack is considered terrorism or a legitimate military target. There was also discussion about the bigger picture geopolitical stuff.

Yeah, so that was a quick rundown of the cool stuff. Lots of tech, some design, some entertainment, and some real-world heavy news. Talk later!
