Here are all of the things I swear by or simply believe deserve a link:
VSCode – A hackable IDE similar to Atom.io, but with author supported debugging, language support, and extensions. An excellent IDE for NodeJS and Rust.
Crouton – The beautiful script to turn your Chromebook into a great development system by adding Linux to it.
Linode – My goto solution for app and site hosting. I often prefer to handle the hosting, and cheap it cheap in the process. Linux and BSD support, and offering $5 micro-systems.
Mancy – A great Electron-based NodeJS REPL. It’s hasn’t been maintained for over 4 years, but still works amazingly for a platform to test modules and abstractions.
