When I first read this, I read it as a compliment to your productivity, but I totally see how you could read that as someone taking a shot at you. I applaud you for this, I read your gist, ran the commands and went from learning about it to using it in less than 5 minutes. Well done. My son loves minecraft, I hope to use this as a spring board to learning how games like this are made. He's 10 and has the aptitude to write code. I see projects like this and Im reminded I need to keep learning and that writing the same C# enterprise app code over and over again is the reason Im not "inspired" to have side projects anymore...
+1 for Glowstone, highly recommended to anyone interested in running a server, one of my favorite projects of all time. A while back it was forked to add improved Spigot plugin support (in addition to Bukkit), later re-merged into mainline Glowstone, extensively under new development so it is worth checking out again for those who have tried it out years ago. Glowstone has a long history!
It even works well as the server backend for my NetCraft client, which is based on fogleman's Craft. The support plugin WebSandboxMC provides a WebSocket client for the web client to connect to, and it runs well on the Glowstone server, compatibility with Glowstone being a top goal.
So with these projects you can have both an open source client and server talking to each other, the full stack open source. The downside, of course, is neither are complete, but it is a start. Open source can only get better (contributions certainly welcomed).
Another project I'd recommend for those in the market for an open source server is Cuberite. It is written in C++ and supports plugins written in Lua. Also has a very active developer community, maybe slightly bigger than Glowstone. Last year I added Forge handshake support, so modded clients with Forge can connect send their mod list, while server plugins can register certain mods as required. Not full Forge mod support, but a necessary prerequisite. The downside of Cuberite is, without Java support, it doesn't have compatibility with Bukkit or Spigot plugins, so there is a vastly smaller ecosystem of plugins available, unlike Glowstone which can use many of them no problem.
Either way, both Glowstone and Cuberite servers, and Craft-based clients (shameless plug for NetCraft/WebSandboxMC), are very exciting and promising projects in my opinion. Personally I have not contributed to either recently, seeing this post I'm tempted to pick them up again, yet for better or worse I've moved onto other things. I'm certainly rooting for them to keep up their open source momentum, could turn into something very cool!
