All platforms that enable UEFI secure boot should ship in setup mode where the owner has

• At some future time, an operating-system- and vendor-neutral certificate authority should be
established to issue KEKs for third-party hardware and software vendors.

As you shiver your way through February, you’re probably thinking about paying your heating bill. But in just a few short months, the summer sun is going to come calling — and the fear of pulling that energy bill out of your mailbox will start becoming very, very real. Air conditioning accounts for about an […]
Despite legalization in 11 states and decriminalization in 15 more, marijuana-based products are still an often tough sell with many Americans. While the psychoactive THC portion of the plant remains controversial, the medicinal impact of the non-altering component of cannibis, CBD, is widely hailed. Many portions of those claims still await medical verification, but for […]
