Happy birthday to me — at the age of 22! I like the way Talor Swift decribe this age in her song “22”, saying We’re happy, free, confused and lonely at the same time. I wonder how your life looks like when you’re at this age — would email or text me a picture or a story, and I’ll text back!

Here’s a prologue on some comments on the course ‘‘Computer Applications for Financial Management". The course design has won multiple awards, and is made to be an obligatory course for all students in Shanghai University of Finance and Economics—for 2 credits, but 64 hours of course loads for one semester. Basically what it does is teaching one how to do Excel to do some higher-level data analysis. It’s a shallow touch into various data analysis perspectives: database tools, a bit of light coding and some basic visualizations....

Final of the Carnival of the Animals, by Saint-Saëns. See an earlier introduction and recommendation of recordings here.

Leonard Bernstein has several recordings of Carnival of the Animals composed by Camille Saint-Saëns. The 1967 recording is notably cool because it features the Bernstein’s charming commentaries. You can for sure read all about the piece via Wikipedia but it’s more fun to listen to the master speak: Your browser does not support the audio element. My dear young friends, music has lots of different uses in life.

When conducting simulation experiments, maintaining an organized workflow is essential for ensuring reproducibility and facilitating debugging. As the experiments grow in complexity, managing outputs such as intermediate results, data files, and visualizations can become challenging. A streamlined approach involves using a logger to systematically store results and organizing all outputs in a structured directory based on random seeds and timestamps. In this blog post, we’ll explore setting up logging, managing directories, and storing results in an organized manner without delving into domain-specific simulation logic....
