From my armchair at Bon Secours Hospital in Galway, wrapped in a blanket, as Infliximab slowly flows into my veins, I decide to write this post. In 3 days, I will be 48 years old, as good a moment as any to look at the failure of a concept that could have changed everything in the world of …

Hello everyone, in my last video, I shared a little bash live-coding session, in which I built a tool to generate SSL / TLS Let's Encrypt certificates, after first running several checks, particularly on the DNS records. It met an internal need, and so I took the opportunity …

Hello friends, this post follows up on the “live admin” video I published a few days ago, where I showed you this addition. If you want to watch it, here it is: Watch the video on YouTube ↗ The Fermi cluster currently consists of 4 nodes …

Technology choices beyond Tech. The “clashes” in the world of Tech over technology choices are nothing new: I have known them all my life, and they undoubtedly predate my birth. I think I was extraordinarily lucky to be born at a time …

This had never happened to me before. Today, a client using an old version of rdiff-backup asked me to restore a file from July, and I ran into this problem: This is a problem I had already encountered once or twice before. It generally …

It is not just fashionable: it works, and nobody can deny it. Having a content strategy tailored to the networks where your target audience spends time, offering value, posting consistently, fine-tuning your posts with both the algorithms and your audience in mind, can really pay off. But …

as if they were heading to the office before they can get to work… Some… but not all! I do not have set hours, whether for working, eating, playing, walking, reading, or sleeping: I have no daily routine. A little more than a year ago now, I launched a new business, which I am going …

Most people face an "alignment problem" between: what they think, what they say, and what they do. In practice, this does not cause most people any particular problems: they have been conditioned to this misalignment from a very early age. Some things « just aren’t said«, even to those close to us. At …

There are two questions I am frequently asked, and my answers never seem to satisfy those asking. The first is about my « daily routine«, and the second is about the separation between work life and private life. And yet, even if my answer never seems to be what people want, it is all true. I have absolutely no …

I have built most of my network of trust thanks to my natural aptitude for discretion. It is one of my "superpowers". It is innate: I have always had a taste for secrecy, and "knowing" has always mattered much more than "having" in my eyes. In a world in which privacy …

“Sovereign”: I can’t stand that word! I do not know exactly when and how this idea began to take root and rot the IT sector from within, but it is time to put an end to this madness! Worse still, the “sovereign cloud”: just reading it makes me shudder with irritation… Why? …

Artificial Intelligence (AI) is here, and for some, like me, that is excellent news. However, I cannot help noticing, with regret, that many of you think AI is going to destroy the world or at best enslave humanity. Yet AI could well be just the opposite: the tool we were missing to save humanity. AI is …

Hello everyone. Many of you regularly ask how I am doing, so I took the time to write this post just for you ;) First, after more than a year of waiting, proceedings and discussions, I am finally bringing an important period of my life to a close. I want to …

"10 tools to become more productive", "my daily routine for improving my productivity": even today, productivity is still considered a key performance indicator, whether for a company, an employee or a solopreneur. I saw it that way too, for a long time. A quick look back: a few …

Why do I keep charging more for my time? I could tell you it is because I gain more experience every day, making my answers or actions more relevant. I could also tell you that I am keeping up with ever-rising market prices, or else, that my "lifestyle …

Well, I had planned to publish a completely different version from the one I made in the video of the same name. For those who have not watched it: it is over here! Watch the video on YouTube ↗ Joshua can talk, but you can replace espeak with something sexier. …
