📝Open source makes systems more extensible

Access to the source code allows small modifications without re-implementing the whole application from scratch.

Open source promotes reuse. Creating a spin-off in open source is called “Fork.”

Examples:

• Vim / Neovim

• XEmacs was a fork of Emacs but (I believe) contributed many ideas back into Emacs itself

• Emacs (What makes Emacs extensible?)

• Linux distros

  • Everybody can create a Linux distro and there are tons of them

• ErgoDox and its variants

• ffmpeg as an extensible media pipeline
