React 19 with JSX, pure client (no build)

· 5 min read

I love simplicity when it comes to software, and for web development I try to get rid of servers whenever possible. For all APIs, libraries or frameworks I use, I want to have a minimalistic HTML page that instantiates and sets up the bare minimum for that tool to work, and that I can load from localhost — no web server required. Those files I use as boilerplate and reference, cloning them for whatever experiment I want to do. Of course, web servers and build steps are great for all sorts of reasons, but sometimes you just want to play around or develop a quick proof of concept.

“The Man from the Future: The Visionary Ideas of John von Neumann”

· 5 min read

⭐⭐⭐

I am a bit embarrassed to notice that this may be the first “biography” I've ever read. It probably is. I'm not sure.

Perhaps due to that lack of experience on my part, I was expecting something a bit different from this book. I had decided I wanted to read it for one simple reason: to (try to) understand what it's like to be really, really intelligent. I had heard all kind of stories about John von Neumann and about his feats. I wanted to delve into that, try to understand how exactly his brain was so different from a normal one. What it meant for him to be so much smarter than almost everyone around him. How he thought, what “extremely intelligent” actually means.

“As a child, von Neumann absorbed Ancient Greek and Latin, and spoke French, German and English as well as his native Hungarian. He devoured a forty-five-volume History of the world and was able to recite whole chapters verbatim decades later.”

Should I focus on trying to retire?

Two years ago I realised for the first time that I end up making the “right” moves in life, but often I make those changes later than the average of my peers.

Owning a house, investing money, getting married, having kids… It's not that I fail at those projects, or shun those life decisions: it's just that sometimes I get to those places a few years later than would be desirable — judging with the benefit (and the bias) of hindsight.

That was stating the obvious, I guess. Of course you want to start earning money earlier rather than later. Of course you want to travel soon, so that you'll have more time to visit more places in your life. You'll probably end up marrying and having kids (like most people do), so why postpone it unnecessarily? And yet, for me, strangely, that was a novel realisation.

Armed with that silly “insight”, in 2023 I noted that

“now that I've spotted a trend in my life trajectory, it should be ‘easy’ for me to course-correct. […] That means making an effort to identify the next life goals, and acting quicker to get there. And so I have been wondering:
What are people my age starting to do now?
What will they be doing in a few years' time?

Thinkers

I asked Claude, ChatGPT, Copilot, Gemini and Grok:

What are the ten most influential thinkers in human history? What ten individuals made the most important contributions to philosophy? They should all be real people who actually existed, about whom we have enough information, who were original in their ideas, and who continue to be discussed and appreciated. Consider philosophers, theologians, social scientists, authors, and any other kind of intellectual.”

Results:

  • Five mentions: Aristotle, Confucius, Immanuel Kant and Karl Marx.
  • Four mentions: Plato.
  • Three mentions: René Descartes and Jesus.
  • Two mentions: Thomas Aquinas, Augustine of Hippo, Avicenna, Charles Darwin, Sigmund Freud, Friedrich Nietzsche and Socrates.
  • One mention (discarded): Buddha, Laozi, John Locke, Muhammad, John Stuart Mill and Mary Wollstonecraft.

⭐⭐ for the entire work; ie, the seven volumes.

I've written about In Search of Lost Time before (book #1, book #2, book #3, book #5), so I won't elaborate here. Some of those volumes I liked (#5 and #6) while others I found quite boring (#3 and this last one, #7).

Proust, looking very casual

It has been quite a journey of five and a half years for me, and one that I'm glad I made. I don't think I'll ever read another ~4,000 page-long novel with so many highs and lows, so many characters, and sentences so long and convoluted. OK, Proust: you're a genius. I'll give you that. Not sure if you could have made a better investment of your talent and the last years of your comfy life, though. And I'm uneasy about your moral compass and your values, to be honest (yes, I know it's fiction and that was not your life — wink, wink).

April 2025, second week

(← Start on the first week)

2025-04-07

Monday 7th
At the office, attending a weekly meeting. This set-up is the best I've ever had: adjustable electric standing desk, two external monitors mounted on articulated stands, and all peripherals (including the monitors) connected via a single USB cable. Plus noise-cancelling headphones and my faithful reMarkable 2, this is the best for work.

April 2025, first week

· 3 min read

Like every month of April since 2008, I'm taking one photo a day to document my routines and the state of my world for my future self (and for some friends and family).

There's no particular theme or prompt in 2025 — in the last years I consider it a success if it doesn't get to midnight and I have forgotten to take at least one picture.

So, here goes my first week:

2025-04-01

Tuesday 1st
Reading in bed, with my wife, before going to sleep. I'm halfway through the seventh volume of In Search of Lost Time.
