The official story is that HDMI is a security measure, designed to stop infringers. It’s been known for years that HDMI has serious security flaws; even Wikipedia discusses them. HDMI’s security woes make a pretty interesting story, which I’ll explore over several posts. First I’ll talk about what HDMI is trying to do.

But how do you make sure stuff gets done? You definitely can’t do all the stuff yourself, unless your company/organization/government office consists entirely of you. And […]
Even the most expensive pair of hi-fi headphones can’t match the feeling of bass rumbling through your body at a live show. That’s why music aficionados designed The Basslet, an accessory that reproduces that sensation from your wrist. Does it make your whole body shake with deep subs? Not really, because that would be terrifying, but […]
They probably just sleep a lot. But still, you can remotely keep an eye on them when you’re at work and missing them deeply with this HD monitor from Kodak.If you have a new puppy that destroys everything in sight, or you just want to be a little more security-conscious, this WiFi camera is a […]
