I had the pleasure of working at CERN (European Organization for Nuclear Research) for over 4 years.
It is one of the coolest and most diverse working environments I’ve ever seen, with plenty of young people and outside work activities. Sitting on top of the border between France and east Switzerland, you’ll find its two large sites where a few thousands of people work every day.
During my time over there I’ve trained and became an official CERN guide, giving tours to the public. If you’ve ever had the chance to go in one of these visits, you have probably…

I’m addicted to fun facts and I love learning about interesting events and quirks of our universe. However, as a computer scientist, I tend to lean towards multi-tasking instead of sitting down and reading a good book (sorry fellow bibliophiles 😅).
Don’t get me wrong, a good book is always welcome! But, if you’re like me, you’ll find many slots of your day which are being underused: driving…
Before you dive into this tutorial, please make sure you are comfortable working with a Linux terminal.
Whether you want to keep an eye on your animal during a short trip away from home, monitor your baby in a separate division of the house, or simply find a way to capture suspicious movement while you’re away from home, surveillance systems are typically the way to go.
However, even though these are widely available nowadays, I personally still find them to be sometimes inadequate. Why? Well:
You already know and use Cloud regularly, but what about Edge?
Cloud, edge, IoT, IIoT, ubiquitous, hybrid cloud, fog, big data…jeez, it’s like people are on acid and coming up with random tech terms just to make us, mortals, get confused.
Well, in this case, albeit being different, all of these terms actual make sense and are tightly interconnected — like a word cloud (pun intended).
Let’s build a timeline a make understand how all these come together.
In the old days, centralized computing was the to-go computing model. Heavy workloads would run in-house, on supercomputers, until distributed computing become…
Edge Computing and Container Technology are growing into billion dollar markets, but how are they related to each other?
Let’s keep things plain and simple, and go straight to the point. Do you now what Edge Computing is? What about Containers?
By definition, Edge Computing is about moving the computing power and data management capabilities to the edge of the network, closer to where data is being generated. This is sometimes simplified as near-data processing.
A container is simply a portable software application, packaged with all its dependencies, which can be executed in isolation from other processes. …
Yep, you read it right…the Docker Certified Associate (DCA) certification has changed so much recently that the majority of the exam is now about Kubernetes.
I just got certified, and I’d confidently say that almost half of the questions were Kubernetes related!
Reelaaax, I passed anyway 😎
But, given that all exams are different, was I just “unlucky”? Or is this where the DCA is heading towards?
There’s plenty of material online for those preparing to take this exam, so I’ll just share my experience and hopefully shed some light on how to study for it.
You might question whether…
