Wi-Fi data helps researchers improve accuracy of mapping algorithms

SLAM, or simultaneous localization and mapping, is a well-studied computational problem that involves updating an environment map while keeping track of an agent’s location. (Typically, said agent is a drone or robot.) The advent of cheap, ubiquitous depth sensors and sophisticated algorithms have solved it somewhat, but even state-of-the-art vision systems aren’t perfect: Symmetric and […]

Spectre, Meltdown researchers unveil 7 more speculative execution attacks

Enlarge Aurich Lawson / Getty Images Back at the start of the year, a set of attacks that leveraged the speculative execution capabilities of modern high-performance processors was revealed. The attacks were named Meltdown and Spectre. Since then, numerous variants of these attacks have been devised. In tandem, a range of mitigation techniques has been […]
