IDG Contributor Network: Before you select a visual collaboration platform, ask yourself these questions

Once you’ve realized how important it is to invest in a digital workplace and have secured the budget you need to move forward with your plan, it’s time to begin looking for a collaboration solution to support this new way of work.Ultimately, the goal is to bring your people, content and technology together in a single, unified content-experience platform that promotes effective team collaboration. To get there, you’ll need to move beyond conventional collaboration applications, which typically include only file sharing or chat, to a more comprehensive solution that includes visual collaboration. But with so many new visual collaboration platforms emerging, how can you decide which one best suits your needs?To read this article in full or to leave a comment, please click here

Dictionary: optic boom

optic boom

A flash produced when electrons move faster than light, akin to the boom of supersonic jets. Breaking the “light barrier” sounds like sci-fi, but physicists say it can happen in graphene sheets. The discovery could spark development of optical circuits a million times faster than silicon chips.

VMware NSX and SRM: Disaster Recovery Overview and Demo

In this post, I’ll briefly expand on the benefits of utilizing NSX as part of a disaster recovery (DR) solution. For additional information check out my prior multi-site and disaster recovery with NSX posts on the VMware Network Virtualization blog. Additionally, I recently presented at 2016 US VMworld and Europe VMworld on multi-site and disaster recovery solutions and recorded sessions can be viewed here: US VMworld, Europe VMworld.

Prior NSX Multi-site and Disaster Recovery Posts:

With disaster recovery, two challenges in general are:

  1. Recovering the application with the same IP address at the recovery site; this is important because typically there are other dependencies on this IP address such as possibly security, load balancer configs, DNS, application dependencies, etc.

  2. Ensuring security for the application is in place for the application upon disaster recovery; traditional solutions rely on manually updating or syncing security policies across the protected and recovery sites which is Continue reading

Happy New Year

Hi Everyone,

I wish you all a Happy New Year!

Currently im very busy studying for my 2nd attempt at the CCDE Practical exam.
I have it booked for the next slot, which is February 22nd in London.

Thankfully there are more and more material available for the CCDE than just a year ago. One of my primary sources are the study group which I have mentioned before, which Daniel (lostintransit.se) and I started way back.

Im also going through the INE scenarios as well as LiveLessons available through a Safari subscription. Those are really good and I highly recommend them.

One of the primary things im practicing at the moment is picking up business requirements from a given scenario. This is quite hard as im at heart an implementation-focused guy. But its good to learn something new and very useful.

If you are not following it just yet, I can highly recommend the “Unleashing CCDE” site on Cisco Learning Network (https://learningnetwork.cisco.com/blogs/unleashing-ccde). There are alot of good posts there on how to pick up these “soft” skills.

I will keep the blog updated with my study progress through February and we’ll see what happens February 22nd ?

Take Care.

Device Configurations Are Not a Good Source of Truth

One of my subscribers sent me this question after watching the second part of Network Automation Tools webinar (or maybe it was Elisa Jasinska's presentation in the Data Center course):

Elisa mentions that for a given piece of data, there should be “one source of truth”. It gets a bit muddled when you have an IPAM tool and Git source control simultaneously. It is not hard to imagine scenarios where these get out of sync especially if you consider multi-operator scenarios.

Confused? He provided a simple scenario:

Watch Steve Jobs unveil the iPhone and change the world

10 years ago today, Steve Jobs delivered one of the most masterful product introductions in history when he unveiled the iPhone. Though the idea that Apple was working on a phone had been making its way through the rumor mill over the preceding few months, what the iPhone actually delivered to the table surpassed even the most optimistic of expectations.With a multitouch display and intuitive access to the entire web via mobile Safari, the iPhone instantly changed the way people used their smartphones. And that's not to say nothing of the App Store which went live in July of 2008 and quickly turned the smartphone industry on its head.Apple earlier today, naturally, celebrated 10 years of the iPhone with a special splash page on its website.To read this article in full or to leave a comment, please click here

Stock-tanking in St. Jude Medical security disclosure might have legs

For better or worse, a security firm’s attempt to cash in on software bugs -- by shorting a company’s stock and then publicizing the flaws -- might have pioneered a new approach to vulnerability disclosure.Last August, security company MedSec revealed it had found flaws in pacemakers and other healthcare products from St. Jude Medical, potentially putting patients at risk.However, the controversy came over how MedSec sought to cash in on those bugs: it did so, by partnering with an investment firm to bet against St. Jude’s stock. Since then, the two parties have been locked in a legal battle over the suspected vulnerabilities. But on Monday, MedSec claimed some vindication.To read this article in full or to leave a comment, please click here

Big Changes in 2017

This past June when I was in North Carolina at Cisco's CPOC lab, I learned that there was a chance-albeit a slim one, but a chance nonetheless-that a position would be opening up on the CPOC team in the fall. By that point I had been to CPOC three times and knew many of the engineers who worked there. I spoke to them to get their feedback, met with the newly-hired manager of the team, and just generally did all the things I thought I should be doing to take advantage of my time being face to face with these folks.

iPhone after 10 years: Google overwhelms the iPhone like Microsoft overwhelmed the Mac

In 1991, Harvard Business Review article Computerless Computer Company by Andy Rappaport and Shmuel Halevi explained how Microsoft’s PCs overwhelmed Apple’s Macs. Most of the article’s wisdom would hold true today if applied to Google and Android’s domination of the iPhone.Since Steve Jobs orchestrated Apple’s turnaround in the late 1990s, Apple has recovered from the near-death experience when when Jobs returned and Microsoft loaned Apple $150 million. Apple is now one of the world’s richest companies in the world and is no longer in what the authors called a battle for long-term survival when they asked the question:To read this article in full or to leave a comment, please click here

A Postscript to the Leap Second

After Two Years, Do I Find Self-Employment Worthwhile?

In March 2015, I started working for myself exclusively. That is to say, I went from working for someone else full-time while also operating my own company full-time to working strictly for my own company. How am I feeling after nearly two years of self-employment?

Fulfillment

Working for myself has proven to be fulfilling. I like the correlations to be found among opportunity, effort, risk, reward, and failure. I can weigh all of those things, make a decision of how to proceed, and benefit (or suffer) directly in accordance with my decisions. That is fulfilling to me.

Suffering, by the way, isn’t a bad thing. We could all stand to do a bit more of it today, so that we do a bit less of it tomorrow.

Process

I am free of silly processes that cripple my ability to get things done, not that I believe process is inherently bad. With my own company, I still have to define processes, but I can keep them both streamlined and fluid. I’m also free to let the people that work with me define their own processes, with me providing only the input required to achieve the desired result.

Balance

When working for other employers as an IT professional, Continue reading
