Security flaw in Qualcomm and MediaTek SoCs

A set of security flaws called 5Ghoul has been published that affect 5G mobile devices that use Qualcomm or MediaTek chips. The flaw allows man-in-the-middle attacks with relatively inexpensive hardware. It affects 700 phone models.

Using diamonds to store information

A group of researchers has managed to store 25 GB of information per square inch by writing 12 wavelengths simultaneously in defects in diamonds. The density is not very high by today's standards, but it is a first step towards achieving a new medium.

Security flaw in UEFI

A good number of security flaws have been discovered in all devices that use UEFI, which affects both Windows and Linux. The flaw, called LogoFAIL, is exploitable if there is an additional security flaw in some running program such as a web browser.

Using a Pentium 4 for current tasks

Someone has been testing a Pentium 4 with current programs and games to see how it performs. It has 8 GB of RAM and thanks to having a PCIe slot, they have put an RTX 3080 in it.

FFmpeg now runs multiple tasks in parallel

The developers of the famous open video encoder FFmpeg have carried out the biggest code refactoring in a long time. This has allowed them to run multiple tasks that are part of the process such as de/multiplexing, filtering and de/encoding in parallel.
