👋 Hey! I'm Orlando an all-round-nerd from Hamburg, Germany.

Currently I'm CTO at Katulu, building a Federated AI Platform that allows organizations to completely cut the cost of lengthy data centralization projects and sidestep many other issues blocking AI projects. You'll likely find me jumping between coding, strategy, research, and whatever needs doing.

This is my personal website, so all thoughts and opinions expressed here are entirely my own. Consider this a fair warning.

P.S. You'll also find me on , and , and may be on , and . Always happy to connect and chat about interesting ideas!

Lost in AI

How the messy but crucial engineering conversations got moved into private agent sessions.

When everything around AI is introduced with such fanfare, when every week brings a model update or a new agent framework or another "this changes everything" announcement, you don't notice the things that just happen. The quiet shifts. The ones nobody announces because nobody decided them. They creep up on you.

Opus 4.7 Flagging Itself

Anthropic's new prompt-injection defense good enough to trip on its own system prompts.

I was mid-conversation with Claude Opus 4.7 when something odd happened. I'd just finished a batch of research and asked it to turn the findings into a document. Instead of generating the markdown, it wrote that it had detected a prompt injection in the conversation.

prelude.ts

A small TypeScript reference library for the FP patterns.

The first WIP commit for this thing landed in 2019. Before that it was not really a repository so much as a loose collection of files: snippets, tiny abstractions, examples I would pull up when I wanted to show someone why some supposedly esoteric functional programming concept was not actually that exotic. The code barely changed over the years. I just kept reaching for it, and at some point I had to admit it deserved a proper cleanup.

Agency Device

Why we see agents where there aren't any.

The first time I came across a useless machine, I felt like it was mocking me, and I knew I wanted one. There it sat, a simple wooden box with a single switch. I flipped it on. A mechanical hand emerged, deliberately flipped the switch back off, and retreated. I tried again. Same result. And again. Each time, that little hand seemed more determined, more stubborn.

You No Longer Need to Code

Learning to programm may still changes how you think.

Lazar Jovanovic is Lovable's first "professional vibe coding engineer." In a LinkedIn short that got some traction, he made the case that learning to code is pointless now. AI writes the code. The problem is solved.

Seductive Answers

Why a confidently wrong AI answer is harder to question than an obviously wrong one.

So there I was, manually cleaning up old files, trying to free up some space on my drive to squeeze in another backup. You know how it goes. Delete, delete, keep, delete... wait, what's this? Buried in a backup from 2014, I found this note about simple answers and stupid algorithms. Reading it now, in 2026, it's both funny and a bit unsettling how spot-on some of it was.

Changing an SSH key passphrase

A while back I wanted to change the passphrase on an SSH key. Mine was painful to type and I'd never thought to question whether it could be changed in place. Turns out it can, and it's a one-liner.

Show hidden files in Finder

Run the following in a terminal to show hidden files in Finder. The defaults command updates the preference; killall Finder restarts Finder so the change takes effect.

git://behind a firewall

The Git protocol is often blocked by corporate firewalls, which becomes a problem the moment your dependency manager — NPM, Bower — wants to clone something over git:// for speed. If you can't get port 9418 opened, you can tell Git to rewrite those URLs to HTTPS instead:
