The Need for Speed: Networking Mimics Processing Power of the Human Brain
As a motorsports enthusiast, one of the things that I have massive respect for is the brain’s ability to process information in extreme situations. The amount of data we can consume and process simultaneously is uncanny. It’s something I directly relate to, having raced motorcycles for many years. Making an assessment of a situation at...

Five Years After Egypt
This week marks a somber milestone in Internet history: the 5-year anniversary of former Egyptian President Hosni Mubarak’s order to shutdown his country’s access to the global Internet amid widespread protests. Similar popular protests would sweep through the region during a time frame that became known as the Arab Spring. Within days of the Egyptian blackout, Internet service would be restored and Mubarak would resign after 30 years in power.
Egypt
On the evening of 27 January 2011 (US Eastern Time), we were alerted to the Egyptian blackout by our BGP route monitoring system. Within minutes, I was assisting my colleague Jim Cowie in Continue reading
Technology ‘net: End-to-end Disaggregation?
Quite a lot seems to be going on on the technology side of things—as the morning paper points out, everything seems to be changing at once right now. Ever feel like you’re sipping from a firehose? Maybe there’s a reason… Let’s discuss just a few of these in a little more detail.
First, there has been a lot of discussion around IPv6 in the last year or so. The folks within the IETF who designed IPv6 decided to do “more than just” adding more address space, instead deciding to change some fundamental things about the way IP works in the process of developing a new protocol. For instance, fragmentation by network devices is gone in IPv6, and the option headers are much richer. These kind of fundamental changes in protocol design invariably lead to the question—what impact do these things have on performance? A recent series of tests set out to answer this question. The results are pretty clear; over time, as IPv6 has been deployed natively, the protocol’s performance has moved closer to the performance of IPv4. There are still some gaps, but they are narrowing. Those gaps may never be gone, but IPv6 may come close enough, over Continue reading
Ansible Galaxy 2.0 Launches
Here’s a quick run-down:
Organizations
There really should be a drum roll playing as you read this, because this feature has been at the top of everyone’s wish list for as long as Galaxy has been around. But here it is… Organizations now have a home in Galaxy. Yes, you can import roles into an organization!
How, you ask? Just click the import button. Really. That’s it. The role will be imported exactly as the repository appears in GitHub. If the role belongs to ‘acmeco’ in GitHub, then it will appear under ‘acmeco’ in Galaxy.
You can import any repositories from GitHub where you are a collaborator or owner. Log in as yourself, and import your roles or your organization’s roles.
Existing roles prior to Galaxy 2.0 have not been changed. To move a role from your username to an organization, delete the role and import it again.
Semantic URLs
Sharing links to your content in Galaxy now makes sense with user-friendly URLs that include GitHub username or organization and Continue reading

Docker Networking on Software Gone Wild
A year and a half ago, Docker networking couldn’t span multiple hosts and used NAT with port mapping to expose container-based services to the outside world.
Docker is the hottest Linux container solution these days. Want to know more about it? Matt Oswalt is running Introduction to Docker webinar in a few days.
In August 2014 a small startup decided to change all that. Docker bought them before they managed to get public, and the rest is history.

Don’t Do Anything Twice
Hello, and welcome to my first blog post! Today I’ll be talking automation and why we automate things, including the simplest response of “it’s more interesting than doing the same thing 15 times a day”. That seems like such a simple thing to say, but it’s boring to do the same thing every day. It […]
