[Isolating Differences Between Files][paper]

Advantage over Other Algorithms

The diff output is more specific:

[I]f a whole block of text is moved, then all of it, rather than just the beginning and end, is detected as changed.

>The algorithm described here avoids these difficulties. It detects differences that correspond very closely to our intuitive notion of difference.

It often be helpful to be able to debug memory usage in Swift on Linux, for example to debug memory leaks.

This is a quick overview of how to generate a report of memory usage for your Swift app. This guide will only show you how to generate the report, not how to analyze it, it might be written up in a blog post later.

Install Valgrind

First we need to install a tool called Valgrind, which is used to trace memory usage.
