A Snap is a universal Linux package that works on (just about) any distribution or device. Snaps are faster to install, easier to create, safer to run, and they update automatically and transactionally so the software is always fresh and never broken. What this means for a normal person is that a tiny computer the size of a Starbucks coffee could be shipped to them and run on their home network. This would then interface with another server they have running in "the cloud". Rather than SSH into a Linux machine and install a bunch of disparate software packages, fiddle with configuration settings, and rage at Apache misconfigurations, a person would instead type something like the following into the public web server:
sudo snap install 10centuries
For those in the IndieWeb who want to take “own your data” to the highest level, 10centuries sounds like an interesting project.
