Antenna tuning at HF frequencies is something that radio amateurs learn as part of their licence exam, and then hone over their time operating. A few basic instruments and an LC network antenna tuner in a box are all that is required, and everything from a bit of wet string to ten thousand dollars worth […]
Selfblow (Don’t google that at work, by the way) is a clever exploit by [Balázs Triszka] that effects every Nvidia Tegra device using the nvtboot bootloader — just about all of them except the Nintendo Switch. It’s CVE 2019-5680, and rated at an 8.2 according to Nvidia, but that high CVE rating isn’t entirely reflective […]
When it comes to something as futuristic-sounding as brain-computer interfaces (BCI), our collective minds tend to zip straight to scenes from countless movies, comics, and other works of science-fiction (including more dystopian scenarios). Our mind’s eye fills with everything from the Borg and neural interfaces of Star Trek, to the neural recording devices with parent-controlled […]
A massive power outage in South America last month left most of Argentina, Uruguay, and Paraguay in the dark and may also have impacted small portions of Chile and Brazil. It’s estimated that 48 million people were affected and as of this writing there has still been no official explanation of how a blackout of […]
As reported by ExtremeTech, the brand new 5G network is running into a major snag with mobile devices as Qualcomm 5G modems literally cannot handle the heat. After just a few minutes of use they’re going into thermal shutdown and falling back to measly 4G data rates. Reports by both PCMag and the Wall Street […]
The entire world has come to depend on satellite navigation systems in the forty or so years since the first Global Positioning System satellites took to orbit. Modern economies have been built on the presumption that people and assets can be located to within a meter or better anywhere on, above, or even slightly under […]
Remember the end of GandCrab we talked about a couple weeks back? A new wrinkle to this story is the news that a coalition of law enforcement agencies and security researchers have released a decrypter and the master decryption keys for that ransomware. It’s theorized that researchers were able to breach the command and control […]
The basic technology of radio hasn’t changed much since an Italian marquis first blasted telegraph messages across the Atlantic using a souped-up spark plug and a couple of coils of wire. Then as now, receiving radio waves relies on antennas of just the right shape and size to use the energy in the radio waves […]
The Bank of England has announced that the new face of the £50 note is to be Alan Turing. This news follows a round of public nominations for a scientist to fill the space, and Turing was in the running with some stiff competition from the likes of Stephen Hawking and Ada, Countess Lovelace. The […]
