Anonymous Nodes for SASSY The anonymous nodes will be resource nodes that use a URI with a fragment that is a generated id. The generated ids in the RDF Redland C library use time and PID as their basis, with a local sequence number for each id generated in the session. This might have collisions in a distributed system - unlikely, but not quite unlikely enough. Something based on a UUID would be better. The UUID library generates a 128 bit random number in 16 bytes. This string is not URI f...

Upgraded to &quot;Not Working&quot;. This laptop is actually a nest of virtual machines. The host does very little beyond running libvirt and its associates. All user data is on a separate drive that is provided to the VMs via NFS from a server VM. I have multiple users defined that I use for different purposes, testing, development, and general stuff. Each of these users can log into any of the VMs (except for one or two special ones) and see all of their data. The gotcha with this c...

I was watching Ms Hossenfelder&#39;s latest on the Fermi paradox. I think that a couple of factors are missing from the Drake equation. It seems to me that there are some significant hurdles that an advanced civilisation needs to overcome for them to be visible to us. We have been assuming that we would see their electromagnetic emissions. This would be true if they were space faring, as its the only way to communicate between worlds (or even moons). Without space travel most communication...

The Next Phase of SASSY This morning I was contemplating what to do next on the SASSY project. The infrastructure is now mostly in place, so its time to move up a level. The make or break part of the project is getting the data out of the knowledge base. Its all a bit pointless without that capability. In order to get stuff out, it must first go in. Hence the next level will be support for data entry. There appears to be three classes of data entry: The first is the classical style for any da...
