New York’s bill banning One-Person Train Operation

news.ycombinator.com Blair Lorenzo 2025-07-20 06:33:47

The New York State Legislature has just passed a bill (S4091/A04873) that would lock New York City’s transit system in the past. This bill, which would require a conductor to be on board every train operated by New York City Transit, is the technological equivalent of requiring every elevator in the city to still be staffed by an elevator operator. If you take other transit systems both across the country and around the world, you'll quickly realize that two-person train operation (TPTO) is an o

Brain Scans Reveal Why Waking Up Is Sometimes Such a Difficult Experience

gizmodo.com Gayoung Lee 2025-07-20 03:00:12

Want to wake up feeling great? The secret might not be so simple as a multi-step nighttime routine, early bedtime, or a no-device rule. A new study suggests that how we fall asleep and how we wake up the next day may not be so similar as we once thought. Neuroscientists tracked 20 people’s brain activity as they woke up from sleep—sometimes naturally, sometimes by setting off an alarm—recording more than 1,000 awakenings in total. They found a pattern of neural activity signaled waking, but tha

Zig's new Writer As you might have heard, Zig's Io namespace is being reworked. Eventually, this will mean the re-introduction of async. As a first step though, the Writer and Reader interfaces and some of the related code have been revamped. This post is written based on a mid-July 2025 development release of Zig. It doesn't apply to Zig 0.14.x (or any previous version) and is likely to be outdated as more of the Io namespace is reworked. Not long ago, I wrote a blog post which tried to expl

Is HR ready for AI?

sefa ozel/Getty Images A report from technology analyst firm Valoir has found that most companies are either already leveraging AI for HR activities, such as recruiting, learning, and talent management, or they plan to do so within the next 24 months. However, there's a significant gap in terms of policies, practices, and training for safe and effective AI adoption.

Hackers Can Tamper With Train Brakes Using Just a Radio, Feds Warn

The Cybersecurity and Infrastructure Security Agency (CISA) issued an advisory last week warning that a key train system could be hacked using nothing but a radio and a little know-how. The flaw has to do with the protocol used in a train system known as the End-of-Train and Head-of-Train. A Flashing Rear End Device (FRED), also known as an End-of-Train (EOT) device, is attached to the back of a train and sends data via radio signals to a corresponding device in the locomotive called the Head-o

How to scale RL to 10^26 FLOPs

TLDR: Reinforcement learning (RL) is the next training technique for building frontier-level AI models. To make it better, we need to train on more data. The current approach of scaling many environments simultaneously is messy and complicated. Instead, I propose we find a way to do next-token prediction on the Web using RL. This way, we learn to reason from general web data, instead of just math and code. I’ve spent a good part of the past year in denial. I was in denial because when OpenAI r

Since the 1970s, countless experts and the US government have sold the public a simple explanation for drug addiction, now clinically called substance abuse disorder: the myth of the gateway drug. The gateway drug — usually cast as weed, alcohol, tobacco, or inhalants — refers to the theory that the earlier a kid starts using drugs, the more likely they are to get into the harder stuff later in life, like heroin or cocaine.
