The proliferation of social and professional networks makes some job boards and headhunters feel pretty old-fashioned. Professional social networks like LinkedIn and Viadeo already play a big role in talent acquisition, while companies like BranchOut, Jobvite and even Monster are building Facebook apps for hiring and career development.

A quiet startup called Greensmith has been building a business out of connecting, controlling and monitoring large batteries installed on the power grid and used for energy storage.

I’ve spoken quite a bit to date about the application-centric nature of cloud computing, and how this changes the nature of operations for the enterprise. That’s all well and good, but it should be quickly apparent that there are some constraints out there that limit what options a team has in where to place and run cloud applications

Report after report points to AT&T marrying Dish Network after Ma Bell’s forced breakup with T-Mobile , but given the companies’ increasing belligerence, you wouldn’t think that was the case. AT&T is petitioning the Federal Communications Commission to impose network buildout conditions on Dish’s satellite spectrum –- requirements that would be passed onto AT&T if it acquired the satellite TV provider. Meanwhile, Dish insists it plans to use that spectrum to build a commercial LTE network to challenge the reigning nationwide mobile operators, including AT&T.

AT&T & Dish fight over spectrum, but will either build a network?

Mobile data is picking up momentum in Latin America as the number of 3G connections in the region doubled in 2011, according to a new report from Wireless Intelligence . Operators in Latin and South America are shutting down their CDMA networks, replacing them with the UMTS systems used by the GSM world, and even making their first moves to LTE

Qualcomm and Ericsson revealed on Thursday that they have successfully passed a voice call from an LTE network to a 3G one, paving the way for mobile carriers to begin migrating their voice traffic onto all-IP 4G networks. That’s a big deal because the sooner carriers move their voice and SMS services to LTE, the sooner they can shut down their pokey 2G and 3G networks and establish a mobile broadband continuum across the airwaves. First some acronyms: the technology Qualcomm and Ericsson successfully trialed is called SRVCC – single-radio voice call continuity – which is a critical step in migrating today’s old-fashioned circuit-switched voice networks to the IP world of VoLTE, or voice over LTE .

So far, Google Wallet has its official US availability on NFC-compatible handsets limited by unfriendly carriers with their own mobile payment services in mind , but it appears that is no longer the case for Nexus handsets with AT&T SIMs inserted. Droid-Life reported the app is available in the market for AT&T-SIM’d HSPA+ Galaxy Nexus phones, which we were able to confirm on our own device (over any connection, as long as the AT&T card is in, switching back to a T-Mobile SIM made it disappear from the market again, although of course the app still worked).

Honeywell's thermostat with Opower software Honeywell, one of the world’s largest thermostat makers, tells me that twenty years ago it tested out thermostats that can learn the home owner’s behavior and adapt the heating and cooling accordingly, but ultimately decided that consumers didn’t take to them, and would rather control their thermostat themselves. I asked Honeywell’s President of its Environmental and Combustion Controls division, Beth Wozniak, in an interview if Honeywell was interested in making learning thermostats, because there’s been so much discussion about the startup Nest, which has created what it calls the world’s first learning thermostat. “We found that consumers prefer to control the thermostat, rather than being controlled by the thermostat,” said Wozniak

In its IPO filing Facebook mentioned the word “mobile” 123 times, which given the term’s buzz worthy status is hardly surprising. But in most cases Facebook didn’t use the word mobile in positive ways. In fact, it identified the proliferation of traffic to its mobile app and website as the biggest risks that its advertising-driven business model faces

Will an idea to build a data center park powered by onsite clean energy and paired with a microgrid in Colorado, represent the future of data centers? Created by developer Craig Harrison, the Niobrara Data Center Energy Park is a proposal for a company or even the government to build one or more data centers on a one-square mile plot of land in Colorado’s Weld County. Harrison says the site is unique in that a natural gas power plant could be built on it (a gas hub is a few miles away), and has a sunny climate that would enable an onsite solar panel farm
