Collection of useful, relevant or just fun places on the Internets for 14th August 2013 and a bit commentary about what I’ve found interesting about them:
Second CCIE, or CCDE? – Russ White talks about the differences between the CCIE and CCDE programs and highlights that CCIE is for practical support & implementation and the CCDE focusesed on design and architecture. These are complementary but different skills.
I’ll take this one step farther: when was the last time you asked your local SE when they’re going to get their CCDE? Or your AS engineer? I can well remember the days when customers would only talk to a CCIE in the TAC. If you’re in a position as a customer to influence certifications in AS, among SEs, or others, use your influence in the same way you would when calling the TAC.
This Is How Your Brain Becomes Addicted to Caffeine | Surprising Science – Fascinating. And because it’s from Smithsonian Mag it’s probably true. I’m a coffee drinker although I’m regulating my consumption these days. Moderation is my goal not abstinence.
In people who take advantage of this process on a daily basis (i.e. coffee/tea, soda or energy drink addicts), the brain’s chemistry and physical characteristics actually change over time as a result. The most notable change is that brain cells grow more adenosine receptors, which is the brain’s attempt to maintain equilibrium in the face of a constant onslaught of caffeine, with its adenosine receptors so regularly plugged (studies indicate that the brain also responds by decreasing the number of receptors for norepinephrine, a stimulant). This explains why regular coffee drinkers build up a tolerance over time—because you have more adenosine receptors, it takes more caffeine to block a significant proportion of them and achieve the desired effect.
It’s like a bingo card of why vendor management platforms are so loathed by customers. A fine rant by Ryan Adzima on the persistent use of poor quality software in infrastructure management interfaces.
VMware, your web client is a joke. The only reason most people wanted it was so they could manage their environment from OS X. Way to screw that one up. A brand new, ground up, web based product and you chose Flash? No. Stop it. Fire the whole team. That product manager is trying to ruin your company. They’d have to be to pick Flash.
Cisco, stop using Oracle databases on the backend when I’m managing 400 devices. You make me pick a “size” for my server but make them all identical except for the crazy amount of RAM. I should be able to do what your management systems do with MySQL or Postgres, or even MongoDB. Even better than that, I can do it on a VM with less than 1GB of RAM.
And let’s just not talk about Java, I’ll let it go if you never bring it up again.
A review of the recent Coursera SDN MOOC – Nice review of a online course in SDN on Packet Pushers.
Back in the springtime of this year, I saw that Coursera was going to be offering a free six-week SDN MOOC taught by Dr. Nick Feamster, an Associate Professor at Georgia Tech’s School of Computer Science. As I had already been learning about and investigating this new SDN world in my free time, I thought I’d sign up and give it a go.

SDN in the Enterprise: aligning with business needs – One of the best ever opening line for a post.
As a long-time practitioner of the art of beating computers and communications systems into submission,
Teren Bryson is blogging at Cisco.com in two articles about the SDN inflection.
Hyper-V 3.0 Extensible Virtual Switch « ipSpace.net by @ioshints – This article on Hyper-V 3.0 and it’s extensible switch framework from Ivan at IPSpace.net is going to be important in the next few weeks.
The difference: Microsoft did the right thing, created an extensible vSwitch architecture and thoroughly documented all the APIs (there’s enough documentation that you can go and implement your own switch extension if you’re so inclined).
I’ve got a bunch of product announcemetnts on my calendar and integrating Microsoft Hyper-V into your SDN network is actually an issue for some companies. Hyper-V doesn’t have much traction in the market and Microsoft’s recent price increases to over $6000 per Datacenter license isn’t going to help Source
