My personal little corner of the internet.
The challenge was simple: make an A5 piece of art that says "The best way to predict the future is to design it." and I got more submissions than I was expecting. The prize for the best one was 50 euros. David Belmonte 🏆 António Guerreiro Artur Teixeira Bruno Reis David Alves Nuno Castilho Tejveer Gill
Yesterday I printed Bitcoin's whitepaper. I've understood how it works for a while — mostly from YouTube videos and articles — but I had never actually read the original paper. It's surprisingly short and simple. Crypto isn't new to me. I've mined Ethereum, Monero, Zcash (and ZenCash, which later became Horizen). I really like Stellar and TON networks too, but that's a story for another post. Why…
Am I afraid of AI replacing me? No, but I am afraid of engineers like Rui Silva, and Artur Teixeira (and some others I know) eating my lunch. Jokes aside... These were previously 10x engineers. I've seen them work. They are amazing. Learn a lot from them. And lately I've seen how they are working with AI, and let me tell you. Awe is a good word for it, a bit scary maybe. They leverage it like…
TL;DR: I'm giving away 300€ — 10€ to each of the first 10 followers, 1€ for the next 100, and 25€ if you get a CEO/CTO with infrastructure challenges to reach out to me. People I know only. Timeless Relic on LinkedIn . I am giving away 300€. I will pay you 10 euros to follow my company LinkedIn page. Today on a break walk in the small but amazing park/mini forest of Parque Central da Asprela I had…
I have this meh relationship with social media. I dislike what it does to people — the human brain, attention span, all of it. I forsook it for some years. Deleted everything. Slowly I got back at it. And finally I found a balance to the point I don't even remember I have it, I don't check it, I sometimes forget to check messages on Beeper. Most digital social interactions happen on WhatsApp and…
How I manage the infrastructure of skeeled alone? Plot twist: I'm not really alone! Over the past 5 years, I built and managed what is today skeeled's infrastructure. I worked alone, but with the trust and guidance of Rui, my manager, who knows infrastructure well and trusted me completely with this task. All while staying confident in our stack and sleeping well at night. This was accomplished…
Last Tuesday (Nov 18, 2025), 20% of the internet was "down" due to some proxy issue on Cloudflare. skeeled was affected by this. João (our Quality Control Analyst) asked me if I broke our non-production environment (again). Soon after, we received a message from Eric (our Head of Customer Success) that some clients were experiencing issues. Quickly we noticed something that had never happened to…
This post is a public archival of a self-contained shell.nix file to use multiple channels of Nix. In this case the default and unstable channels.

Hello, world! My name is Miguel Carneiro but you can call me Mig. I am also known as mig4ng. More about me here . This is my very first and awkward hello world article. Breaking the ice is never easy and this article's purpose is to break it. Therefore, I will try to make it as short and embarrassing as possible so all articles that come next should feel easier to publish than this one. You are…
