Vacation time is just around the corner and, if you're thinking of upgrading your photo gear for summer fun, I have some ideas. In Short Circuits: Adobe updated Lightroom this week and there's a really cool feature that I'm looking forward to trying. Facebook hints that it may develop a video-only service. In Spare Parts (only on the website): Chrome may be one of the safest browsers imaginable, but that doesn't mean you can forget about rogue software. And the US Computer Emergency Readiness Team is warning about a threat called "Dorkbot".
