Containers: the packaging that changed how applications travel At the end of the twentieth century a common problem in data centers was the “it works on my machine” issue. An application t...
HTTP/3 and QUIC: the new protocol making the internet faster If you have ever wondered why a page takes a while to load even though you have plenty of fiber, the answer lies in something deeper than b...
For more than half a century, the word “disk” described something literal: metal platters spinning at thousands of revolutions per minute, with a mechanical arm positioning a needle to rea...
When you press play on a series, tens of megabytes per second start moving across your screen without you lifting a finger. But behind that gesture there is a chain of processes we rarely stop to look...
Imagine a car that drives itself. Without anyone touching the wheel, the vehicle decides when to brake, when to turn and how to dodge a pedestrian crossing unexpectedly. This is no longer science fict...
Quantum computing: when computers stop counting one by one You may have heard about quantum computing and it might sound like science fiction. However, it is one of the most promising technologies of ...
For years, the password was the master key to our digital life. A set of letters, numbers and symbols that we had to memorize and change every few months. Today, more and more devices ask us for somet...
Have you ever stopped to think about how your phone knows exactly which street you are on, or how an app warns you about the traffic jam just as you reach the roundabout? Behind that small everyday mi...
Blockchain: the chain of blocks that is changing how we trust the internet When we hear the word “blockchain”, most of us think of cryptocurrencies such as bitcoin. But this technology is ...
Can you believe everything you see in a video? Less and less. Deepfakes, fake videos and images created with artificial intelligence, have become so realistic that we no longer know how to tell the au...
A few years ago, taking a photo at night with your phone was almost an ordeal: everything came out dark, blurry or full of grain. Today it is enough to press a button and the image appears sharp, well...
We all have a drawer at home full of devices we no longer use: a phone that ran out of battery, an orphan charger, a computer that no longer starts. Those objects are not just any rubbish: they are pa...
Do you remember that film where the protagonist puts on some glasses and suddenly sees information floating over the real world? Well, that scene is no longer science fiction. It is called augmented r...

Do you remember the last time you paid for something? You probably took out your phone, held it near the card terminal and, in a second, done. No cash, no card, no signature. That very quick gesture h...
When you log into your bank from your phone, make a purchase online or send a private photo, you do not think about what happens behind the scenes. But each of those actions is a small struggle agains...
We live surrounded by objects that connect to the internet. The watch that counts your steps, the thermostat that adjusts the heating, the light bulb that turns on with your voice or the fridge that w...
Where are your photos when you upload them? And those work documents that you consult from anywhere? The short answer is “in the cloud”. But that cloud is not a magical place: it is data c...
Robots are no longer just a thing of science fiction movies. They are increasingly present in factories, hospitals, warehouses and even in our homes. But how do they really work? What makes them capab...
The battery that promises to charge your phone in minutes We all know the scene: the phone runs out of battery just when you need it most and you have to look for an outlet, with the anxiety of the pe...
You type a word, press enter and, in less than a second, thousands of results appear. It is such an everyday gesture that almost nobody stops to ask what has happened in between. The answer hides one ...
When we think of computers, we imagine machines that process zeros and ones. Quantum computers do something very different: they work with tiny particles that can be in several states at once. It soun...
From the dictionary to the brain: the revolution of translating without a dictionary A few decades ago, translating a text from another language required thick dictionaries, hours of consulting and qu...
Imagine a source of energy that does not pollute, that barely generates waste and that could power entire cities with a minimal amount of fuel. It is not science fiction: it is nuclear fusion, the sam...
When you open a website, make an online purchase or log into your bank from your phone, there is a lot of invisible technology working so that nobody else can see what you do. That invisible shield is...
The steering wheel turns on its own. The driver’s hands — if they can be called that — rest on their lap while the car brakes at a traffic light, waits for a pedestrian and resumes driving witho...
When you ask your phone what the weather will be tomorrow, when an app suggests the perfect song or when an email ends up in the spam folder without you having marked it, something more than classical...
There is a technology so small that it cannot be seen with the naked eye, not even with a normal microscope. It works at the scale of atoms and molecules, where the rules of the world we know change c...
For decades, computers have followed the same rules: they think in bits, which can only be 0 or 1. Everything we do today — watching a video, sending a message, playing — comes down, in the end, to mi...
