Ten Lines of Code That Changed My World

The article recounts a series of significant lines of code that the author found impactful throughout their life. One line, "Hello world!" introduced the author to the concept that computers would execute anything they instructed it to. Another memorable line, "touch filename.txt," allowed them to generate empty files quickly, becoming an indispensable tool from Windows NT to Windows 7.

The author also shares a batch script that enabled them to cheat in games by manipulating the binary code in memory, which led to a profound realization about the malleability of game mechanics. On Linux, a single command, "rm -rf /" as root, could solve any problem, a solution that became a go-to fix for many in the early 2000s.

In the 90s, the author and friends developed a rudimentary username scanner in Borland Pascal to exploit dormant accounts on a newly set up LAN. Lastly, the author is proud of a CSS animation consisting of 280 characters that ran in an empty document, an impressive feat of minimalism and creativity.
