Deep dives

Journey Through Legacy Code

Working with a legacy codebase can be an eye-opening experience for new programmers, as illustrated by Jimmy Miller's first job at a credit card processing company. He encountered a sprawling mess of hundreds of thousands of lines of C# and Visual Basic code, along with a massive database containing over 1,024 columns.
