Check out this post I wrote for Corgibytes about balancing maintenance work with new features when modernizing software. Special thanks go out to my fellow Corgis for their constructive feedback. They convinced me keep the overall idea but re-write my first draft. Plus they fixed my spelling and grammar errors that regular readers of this site are used too.
With the current virus issues I forgot to publicize that my presentation about creating pleasant development environments was posted along with an example of Dockerizing an existing Rails application. You can find the slides for the talk here. Finally you can find a ready to use existing Rails template that uses Docker here.
Thanks to YEGRB for allowing me to present and to Will for his awesome editing skills. Also thank you to Corgibytes for feedback on draft presentation.
