In this blog I’ve often mentioned the name of my late friend Bertrand Dufresne, who passed away 10 years ago this year. Despite all the good memories I have with him, I wanted to remember him through an object he offered me once. The eiPott was this short-lived thingy made by Koziol in 2010: a small, colorful...
This year I decided to treat myself with a new keyboard, and I’ve chosen the Keychron Q3 Max; this post is a short summary of my impressions after a few weeks of use. To begin with, the mandatory TL;DR: I love it. There is no way to put it; this is by far the best keyboard I have ever owned, and I cannot believe I...
Ten years ago, almost to the day, I delivered what turned out to be the “best-selling” talk of all my conference speaking career, with effects that I can feel to this day. I was invited by my friend (and community extraordinaire) Junior “Bonto” Bontognali to talk at the first edition of the App Builders conference,...
People don’t really learn new programming languages every year anymore thanks to AI, so why do I stick with this activity? Call me old fashioned, but I still like to dive into a new programming language every year, no matter what, and thus here comes yet another update in my lifelong obsession to learn more and more...
A few weeks ago I told the story of the exams I passed to enter the “Bachillerato Bilingüe” class in my high school. Among all the things we had to learn for the exam there was the elimination algorithm to solve systems of linear equations, which I’m going to quickly show here. $$ \begin{cases} (1) \quad x + y + z =...
I’ve recently got myself an Elgato Stream Deck, and although it doesn’t natively support Linux, there’s a nice app called Boatswain that does the trick (not to be confused with the OCI container monitoring app of the same name). I tried to connect Boatswain to my Flatpak-installed version of OBS Studio (of which...
There are three epic music albums, released in the seventies and the eighties, produced by musicians from the other side of the Atlantic (Irish and British), that describe the United States much better (and even in a prophetic way) than what the Americans ever could (or wanted). The three albums are, in order of...
In November 1989 I passed the entry exams for the “Bachillerato Bilingüe”, aka the “Bilingual Bachelor”, a parallel study program that existed in my high school, and which gave access to the coveted “Baccalauréat International” degree; turns out my school was one of the few in Latin America that had that...
I had written this article for the “Spreadsheets” edition (#84, published September last year) of my magazine De Programmatica Ipsum, before opting to pen another (much more appropriate methinks) about Felienne Hermans; but I still like this one, so here it goes in its entirety. In this magazine we marvel at the...
During most of the 1980s, I woke up every morning at 06:30. By then my mother was already awake, preparing breakfast and getting ready for work, usually starting her day half an hour earlier than me. I vividly remember that Sanyo (or was it a Sharp?) huge digital radio alarm clock next to her bed, one of those with...
I like having my Zotero library tidy and ordered, which means having proper tags for each item that I import, but I was missing an option to quickly list those items without tags. If you have plenty of items in your Zotero library, and you need to find those that don’t have at least one tag associated with them,...
My favorite place in the city of Geneva is the main train station of Cornavin, because I can quickly jump on a train and leave that shithole of a city behind me as fast as possible. To a large degree, and I don’t chew my words, Geneva is a shithole and definitely the place in Switzerland that I abhor the most. Maybe...
