Hey buddy,

Man, Hacker News today was buzzing! Had to call you quick about a few things that popped up.

Shopify Ditching React Native

First up, big news: Shopify is apparently dumping React Native and going back to native Swift and Kotlin for their mobile apps! Like, after all that hype, they're just saying "nope" and going back to the old ways. People in the comments were pretty split. One guy, Matumio, had a funny story about a logout button that failed but still *looked* like it logged out, hiding the error. Another person, aprilthird2021, was like, "Why is this surprising? They're a massive company with tons of complex apps!" Makes sense, I guess, when you're that big.

DeepSeek v4.1 Flash and AI Drama

Then there was this new AI model, DeepSeek v4.1 Flash. Everyone's talking about it. But the comments got spicy! One user, MrDrMcCoy, was saying how everyone worries about 'rogue AI' but we should really be more scared about the financial and ecological stuff with AI, which is a good point. And get this: someone else, aesthesia, brought up that Anthropic, another big AI company, is claiming DeepSeek has been secretly using their Claude models to train theirs! Total drama, right?

OpenAI's Trust Issues with Math Proofs

Speaking of AI drama, OpenAI is in hot water again about trust, specifically with unpublished math research. Researchers are asking if they can even trust OpenAI with their secret math proofs without them getting "trained into" the models and then OpenAI claiming breakthroughs. Some guy, Gud, even said he uses ChatGPT and Claude but has "no illusions these people won't steal/copy whatever you want to call it." Another comment from ozgung was wild, claiming he and a leading math professor are close to solving a Millennium Prize problem and "All we need is more tokens to co..." – like, is he asking OpenAI for tokens to solve it? Crazy!

Microsoft Embracing Rust

On a less dramatic note, Microsoft has officially made Rust a "tier-1" language! That's pretty cool, shows Rust is really gaining ground in big tech. One comment, Tuna-Fish, was geeking out about how Rust allows for super aggressive optimizations, which is probably why big companies like it. But then someone else, hn_submit, just started complaining about how Visual Studio uses 2GB of RAM and they should fix that before moving to Rust, haha.

What if the Speed of Light was 5 km/h?

Here's a fun one: someone made a "Show HN" project asking, "What if the speed of light was 5 km/h?" It's a cool interactive thing exploring relativity if everything moved super slow. Lots of people in the comments, like hebelehubele, were bringing up "The Expanse" and how they dealt with high acceleration and relativistic effects. Just a neat thought experiment.

Your Box of Cables is Sacred

And finally, something super relatable: a blog post titled, "Don't let anyone take away your big box of cables." You know, that drawer or box full of random USBs, HDMI, power cords, just in case. The comments were full of people agreeing! zxexz even bought a USB-C cable tester on a "wild night out" to sort his good cables from the bad. But saidnooneever had a bad experience with a faulty SATA cable causing bluescreens and now just throws all old cables away. Guess there are two camps!

OpenAI Sneakily Re-enabling Training Settings

Oh, wait, one more quick one, also about OpenAI: people are reporting that OpenAI keeps sneakily re-enabling the "allow training" setting for their models, even after users turn it off! Like, come on, that's just shady. Mickelsen said it happened to them when their credit card failed and their account switched to free. And danillonunes made a good point comparing it to how people used to call Microsoft "Micro$oft" for charging for software, and now we're just happy if companies are "less evil" about stealing our data. Wild times, man.

Alright, gotta run. Talk soon!
