https://www.redhat.com/en/blog/do-we-really-need-swap-modern-systems Swap is used to give processes room, even when the physical RAM of the system is already used up. In the past, some application vendors recommended swap of a size equal to the RAM, or even twice the RAM. Once the physical memory is used up, swap gets used. As the swap disk is much slower →
Phttps://spectrum.ieee.org/tech-talk/consumer-electronics/audiovideo/lishield-can-block-smartphone-cameras-for-privacys-sake Rules that prohibit photos or videos can prove almost impossible to enforce when nearly everyone carries a smartphone. But a new indoor privacy system has shown how the power of smart LED lighting could prevent people from taking illegal videos of a live events. LiShield has a capability to corrupt digital camera images and videos without →

And on Monday they will announce something new. →
https://www.troyhunt.com/what-would-it-look-like-if-we-put-warnings-on-iot-devices-like-we-do-cigarette-packets/ So how would warning labels on IoT devices that have had serious security vulnerabilities look? Hilarious and also so needed. “Intrusions can occur anywhere”… Or maybe it doesn’t need to be tech/legalspeak. WARNING! This connects to the INTERNET and BAD THINGS may happen! →
https://spectrum.ieee.org/tech-talk/consumer-electronics/audiovideo/mit-shows-how-smartphones-could-peek-around-corners Magically seeing around corners to spot moving people or objects may not rank first in most people’s superhero daydreams. But MIT researchers have shown how they could someday bestow that superpower upon anyone with a smartphone. Their secret to peeking around corners is detecting slight differences in light patterns reflected from moving objects or →
