I’m more of a studio kind of music aficionado, but there are a few outstanding live albums I enjoy, in particular because they include at least a song that, in my opinion, had its best version ever in front of a live audience; here’s the list of those live albums I love, including the songs in question.
Kroki is a wonderful tool I discovered during the time I worked as DevRel: it’s a small open source containerized application (compatible with OpenShift off-the-box) written in JavaScript, that encapsulates as many textual diagram formats as possible under a single unified API, offering a convenient way for users to...
Readers of this humble blog on desktop environments or on tablets are aware of the clock that decorates the left hand side of the screen; well, now everyone can have that nice artsy clock on their mobile devices… and no, it’s not an app.
I’ve been using Atlassian Jira for more than 20 years already at this point, and I have seen a fair share of patterns and antipatterns (that’s Japanese for “fuckups”) and, being the new rambling old man, I feel entitled to spread my dystopian views on the pages of this publication you’re reading right now.
I work at a company that is truly invested into AI and LLMs, to the point that we can internally use (following some guidelines) quite a few tools in our day-to-day work: in particular, we have Gemini, Google NotebookLM, and Cursor available to all employees.
Next December it’ll be 10 years since the release of what is in my opinion the biggest train wreck in the history of movie sequels; certainly a blockbuster worth literal billions of dollars, but in my heart and in my mind, it’s just a failed attempt that needn’t be.
I’ve always been bad at gym. I don’t know if there are many people reading this that know me from primary or high school, but I am sure they would agree that, as good as I could be in other subjects, I sucked at gym, year after year.
Writing articles for De Programmatica Ipsum made me adopt a workflow to read and annotate research papers. Most of the material that I use to write articles for DPI are papers, nearly all in PDF format, some with OCR’d text, some without (particularly older ones).
Back in 2015 I gave a talk titled “Cocoa is the new Carbon: the Future of Apple’s Beloved Framework”, whose presentation has a slide that said “Cocoa should remain for backwards compatibility during 10 years at least, until 2025”.
What I’m going to tell you today might seem incredible, but just the same way as LLMs are banned from many workplaces these days, or mobile apps were outlawed by many an IT department 15 years ago, I was consulting 20 years ago for a large firm (a very large Swiss firm, actually) in which… Open Source code was...
And here we go again with vibe coding: this time with Claude, I translated the Turbo Pascal version of Conway into Netwide Assembler or NASM for Linux 64-bit.
I moved back to Buenos Aires in January 1998: merely 2 days before I boarded the last Swissair flight I would ever take, my girlfriend at the time (and, needless to say, one of the major reasons I had decided to move back to Buenos Aires for) called to tell me that she had unilaterally decided to break up with me.
