Today in Mobile

ZDNet broke the news late last night that Adobe will cease development of Flash for mobile browsers, opting instead to focus on HTML5. As my colleague Erica Ogg points out, there are several reasons Adobe was forced to pull the plug: Flash simply doesn’t work very well on mobile gadgets (and Flash Lite was a poor substitute), it’s ill-suited for low-power devices and touch interfaces, and support for HTML5 is growing fast. But the biggest reason Flash failed in mobile was Apple’s unwillingness to support it. Which is why Steve Jobs once again gets the last laugh, as MG Siegler writes here.

The secret payload of the iPhone 4S: Bluetooth 4.0

People paid a lot of attention to two new features that arrived in the iPhone 4S: The much-improved camera and Siri, the new voice-powered digital assistant. But the 4S also snuck in another feature upgrade, one that’s a ticking time bomb of potential goodness: Bluetooth 4.0.

Today in Cleantech

Let’s hear it for 6LowPAN for home energy management! Looks like Google is indeed turning to 6LowPAN to network its Android-capable smart LED light bulbs, according to Greentech Media. 6LowPAN is the new IPv6 mesh standard for linking lots of low-power devices, which fits the home energy market’s needs. I’ve written about moves by Cisco (via its acquistiion of wireless startup Arch Rock last year) to make 6LowPAN the dominant technology in home area networking. Cisco wants to create an end-to-end IP-based smart meter networking architecture for the smart grid, but hasn’t said how it might enter the home networking space. As for Google, its big [email protected] announcement came with a partnership with Lighting Science Group to make a networked LED over a mysterious wireless protocol — which, according to Greentech Media, will be 6LowPAN. NXP Semiconductor will supply the chips, which ties in to a broader push in the “smart lighting” industry to push their respective wireless solutions to the fore. Big energy services companies like Honeywell and Johnson Controls have their own proprietary systems, while startups like Daintree seek to make ZigBee the standard. Looks like Google’s new announcement puts 6LowPAN in the spotlight as well.
