It's undoubtedly possible to turn a Raspberry Pi into a web server, but it's not always easy. Thankfully, Google just streamlined the process with its new Coder project. The open source tool lets developers build web apps for a ready-made Raspberry Pi web server using only a desktop browser. Coder manages all the files, including any media. The mini PC, meanwhile, only requires a network connection and an SD card reader to store the server. Beyond the hardware, Coder is free to use; if you've wanted a cheap testbed for web programming, you'll find one at the source link.
