Comparing Docker Containers to Virtual Machines
In this GNS3 video, David Bombal explains what makes Docker so popular.
Human Infrastructure And Always Planning to Quit and Move On
I did a video for “Speak With A Geek” where I sat down with David Sparks where I talk about approaching your career in a similar fashion to approaching your technology. Your value to the business is determined by how good you are as a piece of human infrastructure.
When you show you can do it for yourself, the people in charge will see that and want to invest in you to bump you up to the next level of productivity. Human infrastructure is no different than physical technical infrastructure, argued Ferro. You purchase a small infrastructure and then you scale it up, spending more money on it, make it bigger, more valuable, and able to do more. That’s no different in how you invest in yourself.
No matter how good your situation is, Ferro advised to “always have one eye on the door.” There is always a better opportunity even when you think yours is the best. For that reason, keep your skills and resume polished at all times and be available for what’s next.

Running vSphere on Cisco ACI? Think Twice…
When Cisco ACI was launched it promised to do everything you need (plus much more, and in multi-hypervisor environment). It was quickly obvious that you can’t do all that on ToR switches, and need control of the virtual switch (the real network edge) to get the job done.

This post will describe the exercises and solutions for week four of Kirk Byers Python for Network Engineers.
The final exercise of week 4 is the following.
III. Create a program that converts the following uptime strings to a time in seconds.
uptime1 = 'twb-sf-881 uptime is 6 weeks, 4 days, 2 hours, 25 minutes'
uptime2 = '3750RJ uptime is 1 hour, 29 minutes'
uptime3 = 'CATS3560 uptime is 8 weeks, 4 days, 18 hours, 16 minutes'
uptime4 = 'rtr1 uptime is 5 years, 18 weeks, 8 hours, 23 minutes'
For each of these strings store the uptime in a dictionary using the device name as the key.
During this conversion process, you will have to convert strings to integers. For these string to integer conversions use try/except to catch any string to integer conversion exceptions.
For example:
int('5') works fine
int('5 years') generates a ValueError exception.
Print the dictionary to standard output.
The first step is to import pretty print which we will use to print the dictionary.
# Import pretty print import pprint
To do the conversion from years, weeks and days to seconds, we are going to need some constants. Constants are usually defined with the variable Continue reading
