Hard to Avoid, Easy to Misuse: Modern Day AI
Khy Pich Kholine
You probably haven't opened a single AI app today. You've still used AI a dozen times — and that gap is exactly what makes it easy to misuse.
Regret Tracker made me more aware — self-control still does the work

Using my own expense app taught me that dashboards raise awareness, but spending less still comes down to discipline.
Fixed cycle vs Q-learning vs genetic search on one intersection

What I learned running four traffic-light policies through the same Pygame simulator.
93% accuracy is easy to brag about — class imbalance is harder

What building an AI traffic controller taught me about state
Khy Pich Kholine
Lessons from Q-learning that changed how I think about frontend state management.
Treat the Jupyter notebook like a lab notebook
