Visualizing Python internals with actual benchmark data beats dry documentation.

Strengths
  • Half-open range explanations with train car analogies make abstract concepts concrete
  • Measured notebook comparing list slicing vs islice performance with real throughput data
  • Production-focused guidance on when to avoid slicing in hot paths
Weaknesses
  • Limited scope covers only six topics, feels more like a chapter than complete reference
  • No interactive code execution, just static examples and external notebook links

I built an interactive LSM Tree simulator

This actually simulates the full write path — WAL to memtable to immutable flush — and animates cascading leveled compactions so you can watch key movement and file counts in real time. The live bloom-filter checks and amplification metrics are the parts that will teach you something immediately; it's clearly built as a learning/debugging sandbox rather than a production profiler.

A Working Python VM Written Entirely in PL/PgSQL

This repo literally turns CPython internals into rows and stored procedures: object rows, regproc type slots, and an interpreter loop (py_eval_frame) that dispatches opcode handler functions in SQL. It's a clever, hands-on exploration — 103 SQL files, a REPL and 87 tests show serious follow-through — but it's primarily an impressive engineering demo rather than a practical production runtime.
