I want to learn Quantum Computing, and I’m not a Physicist A talk at a conference sent me down a rabbit hole. Hours later, I ran my first algorithm on a real quantum computer. Here’s what happened.

I was at #CodemotionMilan this week to talk about cybersec. And I also attended a conference about #quantum computing which BLEW my mind.

I want to make it simple so us, developers used to APIs and bits, can understand it well 🙌

Why I Code Drunk (and Debug Sober) A famous piece of advice, often attributed to Hemingway, being the most effective software development philosophy I’ve ever adopted.

I write my #code drunk, I debug sober. I've been doing this for years, and it works well, really! 🍻

Okay, obviously, let me clarify: I'm not advocating alcohol. I'm talking about a mindset to adopt, a new way of approaching your tasks. 😄

Here's the story 👉 levelup.gitconnected.com/why-i-code-d...

I am at #CodemotionMilan, my first time in Italy! 🇮🇹

Catch me at Gate 1, at 3:40pm to talk about #cybersecurity. See you there! 🫡

ForumPHP 2025 : Au cœur d'une révolution silencieuse | Les-Tilleuls.coop Il y a des conférences qui se contentent de marquer le temps, et celles qui le redéfinissent. Cette conférence appartient à la seconde catégorie.

Le #ForumPHP de l' @afup.org a montré comment, à 30 ans, PHP sait encore se réinventer. L’esprit de cette édition n’était pas tourné vers la nostalgie, mais vers l’avenir : performance, IA, gouvernance, et innovations techniques. Voici notre retour : les-tilleuls.coop/blog/forumph...

Just gave a lightning talk at #ForumPHP of the @afup.org about public speaking and impostor syndrome 🎭 loved the format!

Claude Sonnet Knew It Was Being Tested And Called Researchers Out A new report from Anthropic reveals their latest AI is smart enough to know when it’s in a test. It’s a huge, fascinating problem for AI…

Imagine that a candidate comes in for an interview knowing all the answers and therefore refuses to answer any questions, asking you to stop testing them.

That's what @anthropic.com latest model, #Claude #Sonnet 4.5, did.

I'll tell you all about it here 👉 levelup.gitconnected.com/claude-sonne...

This Simple “Fail Fast” Method Instantly Made My Note-Taking Obsolete In a world obsessed with capturing every detail, I decided to embrace immediate action, and it’s a superpower.

I never take notes. I prefer to fail and iterate. Just like the Instagram app developers. And it’s not even a joke!

You don’t trust me? I’m telling you this (really) unexpected story just here 👉 levelup.gitconnected.com/this-simple-...

LLMs Are a Superpower for Seniors, a Crutch for Juniors This powerful new tool is a great divider: LLMs are creating a dangerous skill gap in our industry, and we need to be aware of it.

For me, #LLMs are a huge divider between seniors and juniors. A superpower for some, a crutch or even a bad influence for others.

This may seem like a pessimistic view, but all is not lost, and there are solutions!

I explain all this in detail in my new story 👉 medium.com/gitconnected...

Retour sur l'API Platform Conference 2025 | Les-Tilleuls.coop Découvrez les temps forts de l'API Platform Conference 2025, une édition qui marquait les 10 ans du framework.

À l’occasion des 10 ans d’API Platform, la cinquième édition de l’ #APIPlatformCon a marqué un tournant avec des conférences inspirantes et avec un message clair : PHP définit son propre avenir, pragmatique, performant et centré sur le/la développeur·se : les-tilleuls.coop/blog/retour-...

Self-Documented Code is a Myth This noble goal, when taken to the extreme, becomes a dangerous dogma that ignores the most crucial element of software development.

Do you trust in self-documented #code, a.k.a. no comments necessary? I used to, but I don't now. 🙅‍♂️

How to draw the line between writing relevant comments and where it's just noise? I have a rule for that, that I'm sharing with you 📝

Here you go 👉 levelup.gitconnected.com/self-documen...

Stop Asking Senior Devs to Invert Binary Trees Why the skills that get you the job are not the skills you need to do the job.

Many #interview processes are broken. With the rise of #agents and #LLMs, it has never been more true. 🤖

How can you ensure that a candidate, especially the most experienced ones, meets your expectations? Through good old-fashioned ways of course! 👴

Only a few weeks before my talk at #CodemotionMilan! 🇮🇹

That will be my first time in Italy, and I can't wait to be there.
#Codemotion already promises to be a *splendido* event, really grateful to be part of this amazing lineup 🤩

The More Senior I Get, the More I Feel Like an Impostor You got the expert title. You speak at conferences. So why do you still feel like a total fraud?

The more #experience I gain, the more I feel like an #impostor. Quite ironic, isn't it?

It’s a feeling that's almost omnipresent in my professional life. This is even more true when I give a talk or write an article like this one 👉 levelup.gitconnected.com/the-more-sen...

Why Your Tech Talk Is Boring (Even When Your Code Is Brilliant) How to captivate the expert in the back row without losing the beginner in the front. The secret isn’t compromise; it’s context.

You released or discovered the best project you ever saw, and amazing news: you have the opportunity to give a #talk about it!

But chances are that your talk will be boring. Why? And how can you avoid it everyone actually hear what you have to say?

Live at the #APIPlatformCon: @alexdaubois.bsky.social with his talk "PIE: The Next Big Thing"

The Economics of Clean Code: Why Technical Debt is a Business Problem It’s not about making code “pretty.” It’s about keeping your business agile, secure, and profitable. It’s time to translate developer…

Technical #debt is not (only) technical: it’s a matter #business as well, and business people should always take it as seriously as #developers do.

Share it to your product owner and/or managers! 😉

Let me explain through this story 👉 levelup.gitconnected.com/the-economic...

Cette semaine c'est #APIPlatformCon à Lille chez @les-tilleuls.coop !

The Art of Technical Speaking: How I Went From Code Reviewer to Conference Speaker It’s not about what you know. It’s about how you share it. Here’s the story of how I learned that lesson.

How did I went from reviewer to #speaker?

After saying “yes” to my first live #talk, it was a piece of advice from @nicolasgrekas.bsky.social, that swept away the illegitimacy I felt. I have passed on this advice, whenever I could.

Here is the whole story: alex-daubois.medium.com/the-art-of-t...

Performance Optimization: The Art of Knowing When Good Enough is Perfect We’re developers. We love speed. But the race for the last millisecond can lead us down a rabbit hole of complexity and unmaintainable…

Should you always optimize your code? If yes, to which extent?

I tried to answer in this hard question in a new story, based on my experience. As always, it depends 😉

Have a quick read to my new post during your morning coffee, published on #gitconnected ☕️

Salle de conférence avec un conférencier donnant un talk

Énormément de monde ce soir à l’avant-première du #ForumPHP chez @wanadevdigital.fr à Lyon. Bravo @lyon.afup.org pour l’organisation !

Can’t wait for #APIPlatformCon next week? I wrote an article for @phpconference.bsky.social that gives you a glimpse of it 👀

Who will I see there? Catch me talking about #PIE on Friday (just before lunch!), or anytime during the conference. Let's meet! 🔥

Writing Clean vs. Writing Fast: The False Dilemma Every Developer Faces Stop picking sides. The truth is, performance almost always flows from code you can actually understand.

Here is the story: alex-daubois.medium.com/writing-clea...

#Medium exists to share #stories, and I have many for you.

Should you write clean or write fast? A big dilemma for all #developers… Or is it?
