Julia (workshop)
summary
Demonstrates Julia features with concrete numbers and code: shows multiple dispatch by inspecting the 181 methods behind the operator and defining a new plus method for string concatenation; loads a subset of TrueFX foreign‑exchange logs (about 1.6 billion rows*, ~70 GB), converts CSV to a binary memory‑mapped format that loads in ~46 ms, filters and five‑minute windowing across 20 processes and completes a heavy 70 GB filter in ~20 seconds; uses JuMP to solve FX arbitrage instances that output trades achieving a $10,000 target.
