A cyberattack in Dallas managed to set off all 156 alarms in the city

In what may have been the loudest cyberattack ever, a data breach resulted in an hour-and-a-half of blaring sirens in Dallas. The Texas city has a total of 156 sirens meant to sound the alarm for danger, which were themselves a nuisance when the entire warning system was breached late Friday night and into Saturday morning.

“At this point, we can tell you with a good deal of confidence that this was somebody outside of our system that got in there and activated our sirens,” city Emergency Management Director Rocky Vaz told reporters. The hack is believed to have been carried out by someone in the area, city spokeswoman Sana Syed revealed in an email statement.

Given that the hack is said to be the largest ever with regard to emergency sirens, experts are on high alert. “This is a very, very rare event,” Vaz said. While most hacks only manage to trigger a couple sirens at most, this most recent breach was significantly more extensive.

As it stands, city engineers are resetting the alert system, and are slated to complete their work by the end of the weekend. But for now, that means that Dallas residents (all 1.6 million of them), will have to resort to local media, emergency 911 phone calls, and a federal radio alert system should any serious situation arise. This attack goes far beyond an annoying prank.

This isn’t the first time an emergency system has been compromised. Indeed, cybersecurity officials have previously expressed concern over the entire 911 system, which has also proven vulnerable. Currently, the Dallas hack is being examined by system engineers. While the Federal Communications Commission has been contacted, police have not yet been called in.

Trying to buy a GPU in 2023 almost makes me miss the shortage
Two AMD Radeon RX 7000 graphics cards on a pink surface.

The days of the GPU shortage are long over, but somehow, buying a GPU is harder than ever -- and that sentiment has very little to do with stock levels. It's just that there are no obvious candidates when shopping anymore.

In a generation where no single GPU stands out as the single best graphics card, it's hard to jump on board with the latest from AMD and Nvidia. I don't want to see another GPU shortage, but the state of the graphics card market is far from where it should be.
This generation is all over the place

While the laptop industry continues to move toward 14-inch laptops and larger, the 13-inch laptop remains an important category. One of the best is the Apple MacBook Air M2, with an extremely thin and well-built chassis, great performance, and incredibly long battery life.

Lenovo has recently introduced the third generation of its ThinkPad X1 Nano, one of the lightest laptops we've tested and a good performer as well. It's stiff competition, but which of these two diminutive laptops stands apart?
