I've re-implemented parts of Peter De Wachter's Project Norebo to eliminate the dependencies on C and Python. In the past, I've discussed with Michael Schierl the importance we both placed on his in-browser emulator's ability to run even on computers with old versions of Internet Explorer installed and no admin access to install or run other software (such as newer/other browsers, or a copy of Peter's SDL-based emulator). I've done some work so anyone can now use an offshoot of Project Norebo to build system images from the most recent Oberon source code modules even if you have neither a C compiler handy nor Python installed locally. Here's a two minute video demonstrating this: https://www.youtube.com/watch?v=TUpd70Mu0Ek In the video, I actually do two builds: once by opening Build.app.htm in the browser, and another by using it directly from the terminal. (This is part of work I've been doing for triplescripts.org, where I implore people to revisit the assumptions they make about their software projects and ask what it should take for another person to dive and begin working on the code. The idea is that too many times software developers wind up with tunnel vision and assume others have the time to burn to get a "development environment" set up, even though this often isn't necessary. In many cases the build scripts can be made to run using nothing more than what most most people have already installed on their computers--i.e., a browser, which is the closest thing the world has to a universal application runtime. I see this as also being important regarding matters of reproducibility and the long-term preservation of computing history.) Unfortunately, I didn't take the time to make this Build.app.htm work in Internet Explorer. You'll need a reasonably modern browser to make use of it. A hacked copy of the Norebo source tree with my TeroBuild changes applied can be found on Keybase by cloning repo at: keybase://public/crussell/norebo.git And in case you don't have Git or Keybase installed (see what I mean about developer tunnel vision?), an archive can be downloaded from: https://keybase.pub/crussell/TeroBuild.zip -- Colby Russell
