IDG Contributor Network: The rise and rise of the IT chief of staff

At two-thirds of companies today, a senior IT leader is working on the next draft of the IT strategy, or perhaps revising a workforce plan in preparation for a transformation. After that, he or she might chase down some red flags on the monthly IT scorecard or meet with a finance leader to discuss a budget update. And before leaving for the day, this leader might draft a monthly IT team newsletter or put the finishing touches on a deck for an upcoming all-hands meeting.Who is this person, the CIO?No, it’s the IT chief of staff.The CIO role is changing fast as they get involved in product technology, help to shape digital strategy and build digital acumen across the company. The only way CIOs can find time to do these things is to delegate many of the IT management and governance tasks that have traditionally filled much of their calendars.To read this article in full or to leave a comment, please click here

Improving on history

The Linux history command allows users to repeat commands without retyping them and to look over a list of commands that they've recently used, but that's just the obvious stuff. It is also highly configurable, allows you to pick and choose what you reuse (e.g., complete commands or portions of commands), and control what commands are recorded. In today's post, we're going to run through the basics and then explore some of the more interesting behaviors of the history command.The basics Typing "history" and getting a list of previously entered commands is the command's most obvious use. Pressing the up arrow until you reach a command that you want to repeat and hitting enter to rerun it is next. And, as you probably know, you can also use the down arrow. In fact, you can scroll up and down your list of previously entered commands to review them or rerun them.To read this article in full or to leave a comment, please click here

Parked electric cars will power buildings, researchers say

Power-thirsty data centers could receive a new kind of electricity supply that uses surplus juice found in idle electric vehicles (EVs). It uses the cars’ batteries to augment a building’s grid power.Vehicle-to-grid (V2G) technology provides a way to store, then subsequently use, energy in commuters’ cars while employees work during the day. It can also supply power when a delivery fleet is parked at night, researchers say.+ Also on Network World: Smart buildings start with awareness + Cost savings for building infrastructure could be significant in green-electricity applications, such as solar and wind, which require local electricity storage. Installing the batteries needed for green applications is expensive.To read this article in full or to leave a comment, please click here

What makes for a successful protocol ?

What makes for a successful protocol ? Which protocol is successful and why ?   Have you ever been asked these questions  ? As an engineer you cannot say I believe Protocol X is successful or Protocol Y is not.   There is nothing like ‘ I believe ‘. There should always a science behind […]

Worth Reading: Making providers responsible for content

When online content hosts face a risk of litigation over user-generated content, they will respond with overbroad censorship measures that limit individuals’ rights to post and access lawful, constitutionally protected speech. This is true whether the litigation risk comes from the government (as it would under the proposed online censorship bill we’re fighting in Germany) or from private actors. —CDT

IDG Contributor Network: When SD-WAN is more than SD-WAN

As the SD-WAN market has matured, one thing has become very clear: SD-WAN will not exist on its own. The technology is merging with other networking technologies, ultimately becoming a feature of a much larger bundle. While it may be too early to say what this “new thing” will be, the rough contours are emerging.Predominantly, we’re seeing security and SD-WANs merge. Just consider some of the activity: Velocloud recently announced its SD-WAN Security Technology Partner Program to integrate with other security vendor’s products. Viptela (soon to be Cisco), Silver Peak, Velocloud and others have long (well, long in the SD-WAN sense) touted integration with security vendors using service chaining. Cato Networks built its own integrated security and networking stack in the cloud. Masergy bundles SD-WAN (Silver Peak and its own technology) with third-party security services in the cloud. But what’s missing in many of these integrated offerings is the completeness of the edge solution. Companies need more than just an SD-WAN in branch offices. They need firewall, IPS, anti-malware, URL filtering and anti-virus for security. Internally, networking calls for Active Directory, DHCP, DNS, and print services. Externally, the edge may need WAN optimization, bandwidth management, QOS, traffic balancing, Continue reading

Aryaka brings benefits of software defined to remote and mobile workers

It seems over the past few years the world has gone software defined crazy. We have software-defined networks, security, data centers, WANs, storage and almost anything else one can think of. However, the one area that seems to have been forgotten about is the remote and mobile worker, as the benefits of software-defined haven’t reached the billions of employees that work from their homes, road, hotels, airports and coffee shops. Considering the primary value proposition of most software-defined things is to improve application performance, it seems odd that no vendor has found a way to bring these benefits to an audience that comprises nearly 40 percent of the workforce today.To read this article in full or to leave a comment, please click here
