Failure Is Fine, Learning Is Mandatory
“Failure is a harsh teacher because it gives the test first and the lesson afterward.” — Vernon Law
I’m seeing a thread going around on Twitter today that is encouraging people to share their stories of failure in their career. Maybe it was a time they created a security hole in a huge application. Perhaps it was creating a routing loop in a global corporation. Or maybe it was something as simple as getting confused about two mailboxes and deleting the wrong one and realizing your mail platform doesn’t have undelete functionality.
We fail all the time. We try our hardest and whatever happens isn’t what we want. Some of those that fail just give up and assume that juggling isn’t for them or that they can never do a handstand. Others keep persevering through the pain and challenge and eventually succeed because they learn what they need to know in order to complete their tasks. Failure is common.
What is different is how we process the learning. Some people repeat the same mistakes over and over again because they never learn from them. In a professional setting, toggling the wrong switch when you create someone’s new account has Continue reading

Now Is Not the Time to Put Everyone’s Security on the Line
This opinion piece was originally published in SC Magazine.
With social distancing the norm, we’re spending more time on the Internet doing more important things than ever – eg, working, learning, banking, trading, shopping, seeing the doctor and having family time – as well as streaming, gaming and interacting with our connected speakers.
Shouldn’t we be certain, especially now, that no one is eavesdropping, stealing or modifying our data?
Encryption is the primary means of accomplishing that goal. Using encryption, data is scrambled so that only the intended people can see the data. It’s right there under the covers most of the time when you’re on Wi-Fi, Bluetooth, 4G and browsing most websites.
Unfortunately, most online services today still do encryption in a piecemeal manner. Sections along the path are encrypted, but typically there are points along the way where the data is unencrypted and processed in some way before being re-encrypted and sent along.
The good news is that many messaging services – eg, WhatsApp, Telegram and Signal – offer end-to-end encryption, where only the sender and intended recipient can “see” the message. Everyone else along the path – even the company providing the service – can’t see inside. The Continue reading
When people pause the Internet goes quiet
Recent news about the Internet has mostly been about the great increase in usage as those workers who can have been told to work from home. I've written about this twice recently, first in early March and then last week look at how Internet use has risen to a new normal.
As human behaviour has changed in response to the pandemic, it's left a mark on the charts that network operators look at day in, day out to ensure that their networks are running correctly.
Most Internet traffic has a fairly simple rhythm to it. Here, for example, is daily traffic seen on the Amsterdam Internet Exchange. It's a pattern that's familiar to most network operators. People sleep at night, and there's a peak of usage in the early evening when people get home and perhaps stream a movie, or listen to music or use the web for things they couldn't do during the workday.
But sometimes that rhythm get broken. Recently we've seen the evening peak by joined by morning peaks as well. Here's a graph from the Milan Internet Exchange. There are three peaks: morning, afternoon and evening. These peaks seem to be caused by people working from Continue reading

Virtual eXtensible LANs -VXLANs
The tutorial discusses configuration of VXLANs on Arista vEOS and Openvswitch virtual machines. The VXLANs extend an L2 network by connecting VLANs from multiple hosts through UDP tunnels called VXLAN segments. VXLANs use Internet Protocol (both unicast and multicast) as the transport medium. VXLAN segments are identified by a 24-bit Virtual Network Identifier (VNI). Within […]Continue reading...
