AI and IoT: Like peanut butter and chocolate?

If you had to take a guess, what would you name as the two most prominent trends in technology right now? Like most people, I feel pretty confident in choosing artificial intelligence (AI) and the Internet of Things (IoT), not necessarily in that order.But in a rare convergence, in turns out these two trends are even hotter together. In fact, the new hotness is the combination of AI and IoT, manifesting itself in a wide variety of form and implementations in locations around the world.IBM’s Watson wants to bring ‘cognitive computing’ to IoT At IBM, for example, the company opened a Watson Internet of Things headquarters in Munich, Germany, earlier this year. The lab pairs IBM with partners such as BMW, Bosch and Ricoh. The goal, per the company’s Watson IoT website, is to marry cognitive computing (the Watson AI platform) to vast arrays of IoT sensors. The company quotes an IDC report that claims IBM and Watson “can demonstrate the power of cognitive analytics in the IoT."To read this article in full or to leave a comment, please click here

Worth Reading: Is it time to build an anti-DDoS alliance?

A functional “anti-DOS alliance” is only feasible if SP”s are ready to commit to specific frugal investments. These ‘ prudent commitments’ will not require millions of dollars in anti-DOS technology. The commitments will require a change of the SP’s attitude and approach to DOS. It moved from a model that “I’m island on my own” mentality to a model where the SP see their business, network, and services as part of a global interconnection system. This interconnected system requires security collaboration to push back against the DOS Storm that threatens their business. We can break this “change of attitude into three actionable changes which will Clear the Path for an SP anti-DOS alliance. —Barry Greene @Senki

Demand for server specialists increases, but talent pool is small

Almost two-thirds of organizations surveyed say recruiting for jobs in data center and server management is becoming increasingly difficult because of the skills needed, both in traditional servers and converged infrastructure.The findings come from a worldwide survey by 451 Research for its Voice of the Enterprise: Servers and Converged Infrastructure, Organizational Dynamics study (registration required). It found that IT shops have concerns about the long-term costs of using public cloud, and that is causing many IT shops to pull back on their cloud movement and even expand on their on-premises infrastructure.To read this article in full or to leave a comment, please click here

How to use the motd file to get Linux users to pay attention

It seems only decades ago that I was commonly sending out notices to my users by editing the /etc/motd file on the servers I managed. I would tell them about planned outages, system upgrades, new tools and who would be covering for me during my very rare vacations.Somewhere along the stretch of time since, message of the day files seem to have faded from common usage — maybe overwhelmed by an excess of system messages, emailed alerts, texts, and other notices that have taken over, the /etc/motd file has. Or maybe not.+ Also on Network World: Half a dozen clever Linux command line tricks + The truth is the /etc/motd file on quite a number of Linux systems has simply become part of a larger configuration of messages that are fed to users when they log in. And even if your /etc/motd file is empty or doesn’t exist at all, login messages are being delivered when someone logs into a server via a terminal window — and you have more control over what those messages are telling your users than you might realize.To read this article in full or to leave a comment, please click here

How I’ve Attempted to Blog More in 2017

This post has been sitting in the “drafts” folder for a while now. Clearly, since it’s August and is therefore a little late to be deciding on a plan that is supposed to carry through all 12 months of 2017. Regardless, I think it’s still worth sharing how I’ve attempted to increase the frequency of my blogging. My basic goal for 2017 is:

Create more content in 12 months than I ever have before in order to a) significantly build up the depth and breadth of knowledge on my blog, b) increase my skills as a writer, and c) continue to build this blog and the readership as a key part of my online persona and brand.

In order to achieve this goal, I’ve identified a couple of tactical objectives:

1. Reduce the friction between me and the keyboard; make it possible to “just write”.
2. Be able to “just write” anywhere. At home. On vacation. In a waiting room. On an airplane. I should also be able to start a post in one location and pick it up again in another. Indirectly this means I need to be able to write on any of my computers or mobile devices.

In order Continue reading

Liveblog: VMworld 2017 Day 2 Keynote

This is a liveblog of the day 2 keynote at VMworld 2017 in Las Vegas, NV. Unlike yesterday, I wasn’t accosted by the local facilities team trying to get a seat at a table in the bloggers/press/analyst area, so that’s an improvement over yesterday. While I’m aware of (most, if not all, of) the announcements that will be made today, I’m still looking forward to the keynote.

Promptly at 9am, Pat Gelsinger takes the stage to kick off the day 2 keynote. He quickly recaps yesterday’s announcements and activities, and then rapidly dives into day 2. First up is a “fireside chat” with Michael Dell.

Gelsinger brings Dell onto the stage and they dive into a number of questions submitted by folks.

• Gelsinger fields the first question, which is regarding VMware support. He calls on customers to be sure to let VMware know if support, services, products, etc., don’t meet their expectations. Gelsinger refers back to Skyline, which was brushed off yesterday, as a key component of improving VMware’s support mechanisms.
• Dell leads off the discussion on a question regarding quantum computing, artificial intelligence (AI) and machine learning (ML), and other forward-looking efforts. Naturally, he positions his company (Dell Continue reading
