Hello Bug, My Old Friend
summary
A demo called Buggy Tasks demo exercises real bugs: an off‑by‑one delete that removes the wrong item and a priority prediction failure where renamed training data drops samples so an SVM returns the wrong class. Fast iterative cycles get sped up by using an IDE debugger to inspect stack, variables and try calls, and slow, systematic isolation uses git bisect with pytest to find the first bad commit. Profiling tools (cProfile + snakeviz and memory profilers) and minimizing reproduction data complete the workflow.
