Attack of the SaaS clones: https://martinalderson.com/posts/attack-of-the-clones/

I became Senior VP at a multi-million dollar company at age 26. My salary was $600k. This was in 2018. How did I do it? Blacked out lines CEO (my dad) promoted me to SVP. There are no gimmicks. There are no shortcuts.

This is blackout poetry to me

It’s so funny to think about the fact that there’s people out there deferring every life decision to this

🤷‍♂️

Pas sûr de ça. Si tu as du co-author ça peut peut-être suffire.

Best CIs are dumb CIs.

I kept committing on work repos with my personal email. So I built a zsh hook that warns me when entering a repo without local identity, plus a helper with fzf to quickly apply the right one.

If you're a consultant, you might appreciate this one.

Code quality feedback loops in AI dev workflows - Nick Tune How I use automated post-merge reflection to capture, review, and apply code quality feedback in AI-assisted development workflows.

New post: Code quality feedback loops in AI dev workflows

Nothing exciting, just some basic ideas I've been applying, but it helps me to understand where AI-assisted development is likely heading.

Come on… you were right…

The year is 2026. The entire economy is scams. But some scammers are scamming for justice.

Not as fancy ! You made a plugin, I didn’t even think about doing that!

And for the ssh key, I tried a few times a decided that it wasn’t worth my time and I’ll keep your solution in mind if I try doing that again 🙂

Production doesn't care how fast you wrote the code.

Deploying 1000 LoC at once is still proportionally - often exponentially - riskier than deploying 100 LoC, regardless who wrote it.

Je le trouve pas, c’est un truc à toi ?

Faut que je regarde ça, merci !

Tu as des loops par phases de TDD? Tu as un workflow qui est managé en dehors d’un agent ?

We have .md’s 😀 (and a vibe coded node server app for rendering then with a nice mikado graph)

I’m super eager to see how the migration implementation will go and how much of it we will automate.

After reading about Steve Yegge’s Gas Town I’m surprised we are not seeing an Elixir based app for managing agents. The BEAM looks like the natural choice for a system ultra resilient that respawn failing things all the time and passing messages around.

Oh and :
- add commands, a lot of
- sub agents, a lot of that too
- divide the work
- add validation after a task is done with a fresh new context

👈 So far the only bad info we had was because someone didn’t updated one of the source of truth repos for more than a month, but fortunately running our investigate command on the other laptop quickly found out what is the current path in the code.

We heavily really on Claude doing automatic stuff for us, like noticing new vocabulary in documents, code and conversation to build a glossary, updating the plan on multiple files based on feedbacks…

The results are impressive. Making that work properly is based on using good prompt patterns:
- add templates for the result you want
- checklist everywhere
- create tooling with code where possible

We are doing some crazy mad scientist experiments with @nick-tune.me. We’ll probably share more later but so far we have a great tool for pre migration discovery and a migration plan builder based on the mikado method.

I just spent a couple of weeks working with Charles Desneuf planning a legacy migration. And it's kind of mind blowing to get a peek of where software engineering is heading.

Some of the key areas I think are worth focusing on if you're going to try this yourself:

#legacyModernization

I wanted to build a catalog of patterns, questions and issues, and link them all.

« My test are breaking every time
I make a change to a constructor » -> « creation patterns overview » |-> factory or builder

My new passion is adding tests on all shell scripts I have now that it comes « for free »

Vous vous rappelez de ma vidéo d'il y a deux jours où je rapportais qu'un homme était mort dans un commissariat du XXe arrondissement ? Selon le récit policier, il était sur un banc du comico, est tombé et est mort.

C'est lui...

Do you plan to burn your plan testing multiple skills builder skills on multiple subjects to let us know which of them is the best at building skills? 😅

I was annoyed by the multiple merge issues I had with the @readwise.bsky.social plugin on Obsidian because of my git sync between multiple laptops, so I decided to create a custom merge driver.
