Uptime: 63 days and colorfield.space's little Pi Zero has never once felt sluggish to me. I've had a chance to kick the tires a bit; using the bulletin board (cspc), the text editor (chalk), the stateless interface to local chat (gab), gopher, and the great correspondance gaming system (oberon). Sysadmin sloum has even installed a program of my own creation, a link aggregator (linkulator). One of the pillars of the pubnix universe is self-built tools, and colorfield.space is a great example of this. All the tools listed above were written by sloum, and they're all great and novel approaches to their functions. I like the ergonomic simplicity of sloum's UI design style -- each program is very purpose oriented and presents your input options in an intuitive way while leaving out any distracting extras. If you're reading this post and haven't checked out colorfield.space yet, I recommend you give it a shot. In particular, it would be great to have more people test out oberon and talk about what new games could be built for it.
