New virtual networking technologies make convergence real
The fact that there are three distinct SDN models shouldn't discourage advocates of virtualization-based convergence. All three models offer improved Network as a Service capabilities, even though they differ in whether they focus on segmenting connectivity for the isolation of tenants and applications, or managing network traffic.

New Zealand updates cloud code of practice as ACS looks on
The code has two key tenets. The first is not calling the offering "cloud computing" unless it actually is. Cloud computing is defined in the code as: "On-demand scalable resources, such as networks, servers, and applications, which are provided as a service, are accessible by the end user and can be rapidly provisioned and released with minimal effort or service provider interaction."

Feds Move To Open Source Databases Pressures Oracle
"The traditional, burdensome licensing practices of the big proprietary guys have really started to put new kinds of pressure on government agencies," he said. "Most of the licensing firms have come up with very inventive ways to make sure the price per year goes up and not down, and that's in direct conflict with the way government agencies are trying to operate now."

Quick Tips: Breaking Bad Employee Habits
Being motivated is key to high productivity, and 47% of employers value it as the most critical trait. If you have an unmotivated worker, his or her bad habits of showing up late to meetings, not being actively involved in brainstorming sessions, or not coming up with new, innovative ways to help the company may be resolved by teaming them up with one of your top performers.

How Android’s new App Ops controls could encourage privacy by design
It looks like the latest version of Android has an interesting little feature tucked away: granular controls for app permissions. The Android 4.3 feature, called “App Ops”, has just been flagged up by Android Police on Friday, and it looks like it could be a game-changer when it comes to privacy. ... For many developers, however, it could prove an utter nightmare. In the quest for privacy or longer battery life, many users may turn off bits of functionality then later wonder why those elements of the app don’t work.

Global worker communities emerge as Amcor thinks outside the box
“It’s a very decentralised business model that’s focused very much on business groups, which are all based in different countries and on different products,” corporate communications manager Zed Ivankovic said at an IBM social-business event in Melbourne. “From a technical point of view, we’ve found challenges around really simple things that you take for granted when you’re working in a one-site environment – things like sharing files, collaborating on files, and that sort of thing.”

How to improve network performance via advanced NIC options
Most NICs support jumbo frames, which means handling packets, or frames, of up to 9,000 bytes. Jumbo frames contain more data in each packet, so fewer packets are needed to convey data across the network. Throughput improves with less overhead -- packet headers and other packet content -- and CPU overhead shrinks.

How Rackspace hires admins: Textbook questions vs. break-fix challenges
But Walsh said if a candidate doesn't get a strong score on the online test, that doesn't necessarily exclude them from a job. An interview may reveal that a candidate who didn't do well on the test, is "a really solid systems administrator at a pretty high level," said Walsh. ... "We need people who can easily talk through situations with customers, as well as log-in and actually do the work," said Walsh.

Five Forces of Collaboration in a 24/7 Globalized World
Hardly a day passes without reference to today’s “globalized world” or its “borderless markets” as the justification for a particular business strategy. This type of connectedness plays a big part in building and extending a collaborative ecosystem that spans teams, departments and geographies. But to fully immerse a business in a connected, collaborative environment, it’s important to first understand what exactly connectedness is.

What to look for in a software engineering culture
Using the Mondrian tool at Google, we had a very clear code review process, where a changelist could not actually be submitted until the reviewer gave the "approval." Using Github's more lightweight code reviews at Coursera, we've had to come up with our own conventions on top of it, where the reviewer will say "Merge when ready" when they're happy or the reviewee will say "Please take another look" if they want a second review.
