This post deals with investment and finance, applying practical mathematics and physics to financial markets. I also provide a program written in Python that performs an analysis of a portfolio of assets and finds the best selection available.
An updated version of my “trojan asteroids tutorial” that I initially posted in 1997.
I recently looked into the book Starting Forth by Leo Brodie. The examples have been written and tested in GForth. These are my reading notes.

This article describes advanced techniques for native animations on iOS. Specifically, it shows how to animate bezier curves, labels and their content.
This article describes a powerful feature of the Objective-C language: the ability to handle messages dynamically at runtime!
This is a practical example of how the characteristics of a parallel computer determine program optimization. It is based on a real-world physics endeavor. The parallel computers used cost hundreds of thousands of dollars and even small optimizations of 10-20% save thousands of dollars!
This post discusses communication routing strategies for data on massively parallel systems and supercomputers. Optimizations like these one can save thousands of dollars in real-world projects.
If you could go back in time, what would you do different?
These are computer projects I did while or was in high school and while I was a student. And what I learned from them.
Germans complain that service is awful in Germany. I agree with them. However, this also means that there is an outstanding opportunity to distinguish yourself from your competition and make an impression on your customers and/or your clients.
Can you be different and make a difference?
This is an update of the style guide we used when writing the hadron structure paper arXiv:1001.3620.
I originally wrote this in Summer 2009 thinking about the Financial Crisis back then. After re-posting it in Fall 2020 due to the Covid-19 situation this content is still as applicable today as it was back then.
Are we only living short-term today? Was that better in the past?
Some impressions from Korea which I visited for the Baryons 07 conference.
My first time in Turkey and my second solar eclipse.
These are experiences from my first trip to Japan in Summer 2003.
