Many suspect that China’s Tianhe-2 could win the supercomputer speed wars, but there haven’t been real numbers to back up that hunch. We now have some of those figures courtesy of Top 500′s Jack Dongarra, and Tianhe-2 could well be the new leader — by a gigantic margin. The cluster of Ivy Bridge and Xeon Phi chips has benchmarked at 30.65 petaflops when using 90 percent of its nodes, giving it a 74 percent edge (!) over the 17.6-petaflop Titan. There’s no guarantee that Tianhe-2 will hold the crown when the official Top 500 rankings appear on June 17th, but we don’t see any upstart rivals on the horizon. It could be lonely at the top… for a while.

When Ubuntu Linux was still in early development back in August 2004, Canonical founder Mark Shuttleworth filed a tongue-in-cheek first bug: that Microsoft had a majority of PC market share. Little did he realize that he’d have an excuse to cross that bug off the list in 2013. Since computing now includes phones and tablets, he argues, that leaves the traditional PC (and therefore Windows) in the minority versus Android, iOS and other platforms. Whether or not you agree with that market interpretation, Shuttleworth is ready to move on — he feels it’s better to polish Canonical’s own cloud, desktop and mobile efforts than to target someone else. It’s undoubtedly easy for Shuttleworth to make peace when the battle is supposed to be over, but we can’t object to such a healthy attitude.

So, it might not be a surprise that it was in the works, but its official announcement today almost caught us off guard. Here it is, the Samsung Galaxy S 4 Mini. Now we can say for sure that there’s a (yet to be specified) 1.7 GHz dual-core processor, Android 4.2.2, GPS, GLONASS, WiFi, 8GB internal memory (expandable up to 64), and 1.5GB of RAM. The display is a 4.3-inch Super AMOLED qHD affair, which will be kept going by a 1,900 mAh battery, with the shooters coming in 8- and 1.9-megapixel resolutions. There’s LTE support — as you’d hope — in 6 band sets, plus single and dual-SIM 3G versions for certain markets. Color choices are white and black (for now), with no official word on price and availability at this time. Mini, just got bigger it seems.

Pebble’s smartwatch might have launched with limited capabilities, but the list of things it can do keeps growing. Now that the company has released firmware version 1.11, you can add a few more features to that list. The update brings notification and set time UI changes, multiple notification viewing, the wearer’s current speed measured by RunKeeper, swaps the music app’s next and previous buttons and squashes a few bugs. It also installs the Simplicity watchface on the device that’s sure to make minimalists happy. Sadly, there’s nary a hint of a new game in sight so you’ll have to make do with Tetris and Snake whenever the mood for smartwatch gaming strikes. To get version 1.11, launch your Pebble smartphone app and tap “check for FW update.”
