Currently reading: Blue Remembered Earth (Poseidons Children, Book 1) by Alastair Reynolds 📚

I love the book so far.

Reminder to myself: If you are in an argument with life, life wins! Every time. Take it lightly and be a good looser.

Success in life

I ran across this great quote: To laugh often and love much; to win the respect of intelligent persons and the affection of children; to earn the approbation of honest critics and to endure the betrayal of false friends; to appreciate beauty; to find the best in others; to give of oneself; to leave the world a bit better, whether by a healthy child, a garden patch or redeemed social condition;

How to install your SSH key on a remote server

1. Nice way You can install an SSH key by executing ssh-copy-id Now you can log in to the remote server with your password and ssh-copy-id will do the rest. 2. Manual way Append your public ssh key to the authorized_key file on the server. As a one-liner: cat ~/.ssh/ | ssh 'cat>> ~/.ssh/authorized_keys' Conclusion Both commands pretty much do the same. The first way is way easier though.

Rails: Preview your emails with MailCatcher

Do you know the feeling of copy and pasting the signup-link from this development.log? There’s a better way to do this. For our development environment, we use MailCatcher. MailCatcher runs a super simple SMTP server which catches any message sent to it to display in a web interface. Run MailCatcher, set your favorite app to deliver to smtp:// instead of your default SMTP server, then check out to see the mail that’s arrived so far.

Teaching Happiness

Today I watched this documentary, and it deeply moved me. It is about an old teacher, who teaches his students something relevant. Compassion, friendship, and happiness. His work touches me on a deep level. I cried quite a lot. I hope you like the documentary as much as I do!


Here is a skill that helps you to become financial independent, healthier, happier and helps you to grow as a person. It is not very popular these days. But hey — Common Sense these days makes no sense at all. I am talking about insourcing. Insourcing means taking your matters into your hand. It means going for a daily walk, instead of taking those pills against high blood pressure. It means cooking your own food, instead of running to the next restaurant.

Strangers in strange lands

We can remember between 5 and 9 digits. So, why do we value our thoughts so much? Gaze at a flower and it is marvelous. — Look with a mental projection in your head, and you only see a representation. You look at the thought of a flower. You could not accurately describe how a flower looks. How it smells with words. You have to go beyond thought. Beyond words.

The magic of small steps

I discovered the secret how you can achieve your goals. A secret that can change your life. Forever. When we look at people who lost weight, at people who got rich, at happy people, at people who mastered a craft, we only see the results. We see what they are now. And not the path that let them there. We do not see the hours of hard work they put into it.
