> In my first real job, I worked for a company that maintained a large legacy product programmed in a combination of COBOL and Java.

> In order to work on the Java side of the product, you checked out individual files from source control to work on, which 'locked' the files and prevented other developers from checking out the same files.

COBOL + Java and file lock... I thought we worked on the same project and it brought back many nightmares!

But we were using Subversion's lock system and had a proper CI/CD with Jenkins.

So you won, your project was worse!
