GitHub Pages File-Sharing

If you sometimes find yourself needing to share a file over HTTP, there are not many file-sharing solutions you can use.

This action works by publishing files via GitHub Pages behind an obscure prefix path. It updates the repository README with the URLs, so that you have links to the published files.

You can keep the repository secret, and the files are public but semi-secret, so you can share them without concern that other files will be discovered.

This gist kept getting bigger and bigger, so I moved it to a proper repository, complete with a proper NuGet package.

Programming as Theory Building

Peter Naur

Peter Naur's classic 1985 essay "Programming as Theory Building" argues that a program is not its source code. A program is a shared mental construct (he uses the word theory) that lives in the minds of the people who work on it. If you lose the people, you lose the program. The code is merely a written representation of the program, and it's lossy, so you can't reconstruct
