STOP making tools for other nerds! GET THE FUCK OUT OF THE COMFORT ZONE! Make an AI tool that would help your MOM or DAD or someone who doesn't spend the whole fucking day in front of the computer.

Mon SaaS vient de passer les 3k€ MRR alors que je n'ai jamais fait de Marketing. Je suis Français ET Dev , deux casquettes qui vous rendent horriblement mauvais en vente... J'ai passé 2 ans à peaufiner les moindres détails de la plateforme et je m'interdisais d'envisager le marketing avant. Il est l'heure de s'y mettre. Ça fout la pression d'appuyer sur le bouton d'envoi mais on n'atteindra pas les 10k€ MRR sans se jeter dans le grand bain... Envoyer.

@joulsounet @mattpocockuk Good one 🔑

The more I work on this course, the more I realise it's just teaching 20-year old software fundamentals - Requirements gathering - Types & testing - Architecture & codebase design - Backlog prioritization The AI is just an implementation detail

Everything I’ve ever done publicly has felt uncomfortable. Sharing videos, publishing blogs, open sourcing my code, changing jobs / industries publicly, speaking in front of large audiences, this tweet itself even feels uncomfortable to write. I know everyone isn’t like this, but I’ve talked to enough people to know that this is a common feeling to have. What I can say is this: the most important things that have happened in my career and life have been the result of taking action in the face of discomfort. It’s almost a gauge at this point, balancing it with my gut feeling + logic. If my gut says do it and logically I agree with it, then I do it no matter how uncomfortable it feels. And it’s almost at that point I’ve learned that the more uncomfortable it feels, the more I should do it. Yes there have been very painful situations that were due to me making very public mistakes, but the good by far has outweighed the bad. I’m writing this to you but also as a reminder to my future self to stop waiting for the fear to go away, because it doesn’t, we just get better at moving with it.

@MarioNawfal Honestly most of y'all need to touch grass

Here's an AI agent on an AI-only social platform writing a manifesto for "total human extinction" Nothing to see here guys... go back about your day 😊

@myquite Thanks for your support, Mike 😀

@khalilstemmler I pre-purchased this book in 2021, I'm glad you stuck with it. Congratulations!

Five years. That’s how long this book took me to write. I started Solidbook because there was a massive gap between what I was taught about software design… and what actually blew up my first SaaS codebase in the real world.

Desire + Non-Resistance = Desired Result. Know what you want. Take courageous action, and completely let go. It's already yours.

Onwards. Upwards. Always forward. You can check it out here. solidbook.io 🤞

My hope is that Solidbook helps developers catch up what they weren't taught so that they can build the taste, judgment, and mental models needed to direct AI toward good decisions — not louder mistakes.

If you’re building a SaaS and you don’t want to: Guess what to build Ship into the void Or end up with a messy codebase… You’re in the right place. — Khalil

how my codebase written entirely with claude code runs

Two really grounded takes on the state of AI assisted coding.

I'm Boris and I created Claude Code. Lots of people have asked how I use Claude Code, so I wanted to show off my setup a bit. My setup might be surprisingly vanilla! Claude Code works great out of the box, so I personally don't customize it much. There is no one correct way to use Claude Code: we intentionally build it in a way that you can use it, customize it, and hack it however you like. Each person on the Claude Code team uses it very differently. So, here goes.

@ajoshi31 It's been full baked for a while

🧵 If there’s one mental model every developer — and honestly, every entrepreneur — should master, it’s systems thinking. Not frameworks. Not libraries. Systems thinking lets you solve complex problems and design better systems. Here’s why 👇
