Like Google's web search, Twitter started off life doing one single thing and doing it very well. And, just like Google, it's kept adding subtle little enhancements along its way to becoming a mature internet tool. Today, its own famously simplistic search functionality has take a turn through the makeover booth and has emerged shinier, happier, and much smarter on the other side. No longer do you need to have, for example, the specific names of your favorite smartphone jailbreak artists, you just search for the general term and Twitter will do some actual searching for you instead of merely matching your query to usernames. You can even step up to an advanced search, where adding the ":)" and ":(" operators determines whether you'll get happy or downbeat tweets on the topic. Come to think of it, that is pretty advanced. Yo Google, where are your emoticon operators?
Pentax's Optio WG-1 GPS point-and-shoot satisfied geotaggers out of the box, but owners of its K-5, K-r and 645D DSLRs have had to make do with third-party taggers like the PhotoTrackr or Eye-Fi. The new hotshoe-mounted O-GPS1 module fixes that oversight by recording latitude, longitude, altitude, Coordinated Universal Time and shooting angle. Everyday snappers might find an extra hotshoe attachment cumbersome, but astro-photography enthusiasts could well be enticed by the device's interesting "ASTROTRACER" function. This helps you take clearer photos of celestial bodies by using the in-built sensors to calculate a star's movement and then employing the camera's shake reduction system to compensate. Sounds clever, but be advised: this module is only for Pentax DSLRs -- and only for very specific models at that. You'll get full functionality with the K-5 and K-r cameras, and geotagging (no ASTROTRACER) with the 645D. Oh, and you'll need to make sure yo
