* also doubles as a homepage.
These pages are mainly about computer related things: scripts, software tidbits, configurations – just some reference material that I might need from time to time.
GPG/PGP Key – Eric R. Thern (2784-bit GPG Key)
Geochronology and Isotope Geochemistry
My main research interests have most recently focused on ~3 billion year old metamorphosed sandstones from the Southern Cross Terrane, Western Australia, with an emphasis on their provenance and their abundant >4 billion year old detrital zircons.
More information about this, and some recent publications are on the research page.
Computer Systems Administration
Founded Zoidial Incorporated (as a web and server hosting business) in 1998, incorporated in 2000, and continue to manage all the associated computer infrastructure. For a brief synopsis see http://thern.org/zoidial/
I’m into Linux and FreeBSD administration (running Linux exclusively on my desktop too), networking and security. Recent (depending on your definition) projects have included everything in my projects folder, as well as firewalls for multiple OS’s, some FreeBSD administration scripts (some of these are slightly incredibly old)
“Ancient History” of Teaching, 2001-2002: Adjunct Instructor for the Computer Science Department at SUNY Potsdam teaching CIS 100 and previously CIS 495 “Topics in Network Administration”, as well as giving the introductory lecture in CIS 290 “Linux”.
Projects & random tidbits (classy default apache listing)
http://www.thern.org/projects
A currently not-very-orderly directory of projects I have worked on or am working on. Some day I’m going to create webpages per-project and perhaps even sort things and update things. Some of the stuff here is incredibly useful (at least to me) and may be useful to other people as well, but it’s hard to sift through, so, like fine wine, I’m letting it age a little.
