• Programming Games (list of suggestions) e.g.
  • Terminal
  • CodeCombat
  • Flexbox Defense
  • CSS Diner
• Generate synthetic data for linear model with two (binary) explanatory variables (A and B) and different real effects (only A has an impact, both A and B have an impact, the impact of A depends on B) - then look at the estimated coefficients (and their statistical significance) when fitting ~ A, ~ B, ~ A + B, ~ A + B + A:B - maybe use drawdata
• Network simulation with Filius
• wgpu - portable graphics library in rust, also running in the browser - maybe checkout Learn wgpu
• Guess the correlation, dice, hausdorff, p-values (e.g. 2-sample t-test (maybe different difficulties: bar chart, bar + SE, boxplot, jitter)), maybe reverse (draw something with a given dice/hausdorff/p-value) … (maybe using NES.css)
• Visualize OpenAlex data with VOSviewer

2023

• Wikifunctions

• git commit folders
• Nushell - A new type of shell (related: warp, fig, hyper)
• formal mathematical proofs with LEAN (gamified learning)
• Automatically translating webpages of the IT from German to English (any other) and hosting automatically on a wiki? (remember the accessibility aspect here…)
• APL "an array-oriented programming language that will change the way you think about problems and data" - solve some example problems. Example: +/(⍳6)∘.=?10000⍴6 gives the frequency of each number for 10000 dice throws.
