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

gizmodo.com Rhett Jones 2026-01-21 09:10:56

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

At least two people died in New Jersey Monday amid flash floods sparked by extreme rain. The torrential downpour lashed vast swaths of the Northeast U.S. Monday, inundating New York City, New Jersey, Pennsylvania, and the Washington, D.C. metro area. Fast-rising waters stranded vehicles, shut down transit lines, and prompted water rescues across the region, just a week after flash floods killed more than 100 people in Texas; as of Monday evening, there were at least 185 reports of flooding acro

How to scale RL to 10^26 FLOPs

news.ycombinator.com Jack Morris 2026-01-21 23:47:34

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

As the United States struggles to keep its major cities connected by even the most barebones rail systems, China is screaming into the future with the development of a levitating bullet train. Called "maglev," short for "magnetic levitation," the train system is designed to levitate via magnets as opposed to wheels.

New Study Flips Everything We Know About Addiction Upside Down

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.
