“I suck”. It’s not the easiest thing to say to yourself while staring in the mirror. Yet, that’s true. I just sometimes feel like I turned into someone who talks but never delivers. How do I “unsuck” myself was my second thought.... Continue: www.mantcz.com/blog/charact... #startups

As I’m approaching 2026 and reflect on what’s ahead of me, I like to come back to first principles: 👉 optimising for happiness 👉 optimising for challenging work 👉 optimising for positive dent on the universe Not in a self-help way, but as a selection mechanism.

Wow 😀 Just got my first NON-FRIEND subscriber to Compiled AI! Feel like such a great milestone. Someone who doesn't owe me any favours actually thinks my #AI newsletter is worth their time. Sake bar, here I come! 🍶🎉

Shipped my second newsletter issue. It's rough. But it's real. This week: Why your LLM is nondeterministic, Warp's new AI agents, and Microsoft hedging their OpenAI bet. cmpld.ai/issues/002/

#AI is 90% artificial, 10% intelligence. We’re building very sophisticated autocomplete systems and calling them intelligent. Don’t get me wrong—they’re useful! But let’s stop pretending they ‘understand’ anything. The magic is in the engineering, not the intelligence. 🤖

I still think that running containerised apps in a simple way is an unsolved problem. Am I wrong? What would you use to run a single container?

Don’t need much to be happy… 😃

That moment when you realize you've been doing pwd → manually copying the path like a caveman 🦴 Just add this to your shell config: alias pwc="pwd | pbcopy" Now "pwc" instantly copies your working directory to clipboard. Such a simple thing but it genuinely sparks joy every time I use it.

🔥 The ability to keep chatting with Claude Code whilst it's executing tasks is a bigger deal than it sounds. Every other LLM blocks input during execution. Claude Code just... doesn't. You remember something? Add it. Requirements change? Update them. No restart needed.

I would connect to LLM and voice, teach it to swear and call it Gordon 😂 youtu.be/Qbbx9wS66Pc?...

Been running pre-commit hooks alongside #AI coding assistants for a while now, and it's genuinely a game-changer for code quality. The secret sauce? Make "--no-verify" a forbidden phrase in your rules.

If you make a favicon for your new project, you deployed too late. If you don't, it looks shit. So, I just make favicon.svg as a circle using brand colour as background. It takes me no time, and looks much better. #buildinpublic

Claude in action...

You work on a new product. You need to capture user emails for potential newsletter. What are your options? What's your experience? Is it just me or this is still pain in ..., you know where 😂 #buildinpublic

"It doesn't feel like the #AI future is near because... checks notes ...Google Workspace Support just responded to 'Can I downgrade?' with an essay about AI features and price increases, never answering the question. We've achieved artificial intelligence but somehow lost actual intelligence...

When Microsoft builds support chatbot...

Like my wallpaper?

Do you have 39 mins? Then read Jakob Nielsen’s article on Top 10 UI Annoyances. It makes me wonder though. What would be Top 10 #AI Annoyances? Any candidates? open.substack.com/pub/jakobnie...

Something we, and by “we” I mean #AI companies pushing at full speed, don’t do often enough: stop and think what are we doing, what will be the consequences of our actions. We should…

There is a benefit of traveling through Europe as a passenger. I can finally tidy up apps on my phone and delete old pictures 😀

Why this was never adopted is beyond me 😂

The PAC CLI is almost here 🛠️ > pac create ticket "jwt-auth" > pac validate --fix > git add . && git commit Finally, a product management workflow that feels natural to developers. Coming soon in v0.1.0 ⚡ #productascode #ai github.com/productascod...

🔪 The Chef's Knife Principle "Product as Code creates friction and pulls us away from users" But does a sharper knife make a chef less connected to their diners? No - it makes them more effective at serving them. mantcz.com/blog/the-che... #productascode #ai

AI coding assistant: "What auth system are we using?" Me: "JWT with refresh tokens, 24h expiry, like we discussed 10 minutes ago" AI: "Got it! What about the user model structure?" Me: throws laptop out window Anyone else living this nightmare? 😅 #productascode #ai github.com/productascod...

🛠️ Coming soon: PAC CLI v0.1.0 > pac init > pac create epic "user-auth" > pac validate Version-controlled product management that your AI coding assistants can actually understand. The future is git-native product development 🚀 github.com/productascod... #productascode #ai

Conversations with Claude Code. Always worth asking... #buildinpublic

Adding pre-commit hook to your local set up is the best way to keep #ai coding assistants in check. #buildinpublic

I always loved Conventional Commits. Time to start using new type "ai". #BuildInPublic #AI

“Life is like a box of… chips” 😂 when i let autocomplete till the end

After years of #AI coding tools leaving me frustrated with context switching and vicious loops, it hit me: What if product requirements were version-controlled like infrastructure? Perfect AI context. Every decision traceable. Zero tool switching. mantcz.com/blog/introdu... #productascode

If that’s true, take my money! 💰 😀 youtu.be/v1Q4Su54iho?...

My favourite command to LLM: "Close this ticket and start working on another one." This is only possible when your product requirements live as structured data in your repo alongside your code. Introducing Product as Code: GitOps for product management 🚀 mantcz.com/blog/introdu... #productascode

AI coding tools write great code but get stuck in loops because they don't understand WHY youre building features. Your requirements are scattered across Jira, Slack, email. Zero context for AI. What if we version-controlled product management like we do infrastructure? mantcz.com/blog/introdu...

“providing an intuitive user interface” The biggest lie in software development 😂

Brainstorming with #ai models is way better than brainstorming with humans. There, I said this.

The most annoying "feature" of Claude in desktop app by far is the fact that it is not great at rewriting and updating documents. It messes them up a lot, to the point that I have to ask it to write it from scratch.

A small tip. If you need an email for a new project, don’t need to buy new service. You can use free email redirect on Cloudflare if you have a domain with them. #buildinpublic

one ticket = one branch = one PR That's been my mental model for a long time. The smallest unit of dev work.
