Q: Is the server and are all the snippets backed up? Yes. We have a daily backup of all sofware and all snippets (public and non-public) to another machine. We are looking for contributors who agree to store additional backups. Q: Can I host a computation server of my own? You can run snippets locally (see magic.jar). The whole software for running a web site like tinybrain.de is not yet public, but if you'd like to do that, you can inquire.
