the future of poofygoof backups

I never did find out what exactly failed with my DLTs, and lost data from the backup server itself. luckily nothing lost was critical, and I was able to rebuild my previous amanda configuration. backups are successfully running again.

cascading backup failures

when my backup server died a couple weeks ago, I figured I could replace the motherboard and continue on my way. I did just that, and replaced the VIA C3 with a Pentium Pro and continued on. the change in setup seemed OK, backups appeared to continue running, and it wasn't until attempting to recover from a root drive failure a week later on the backup machine that I found out the hard way that anything was wrong.

farewell aragorn

looks like my 800MHz VIA C3 machine has finally bit the dust. I must have a dmesg around here somewhere. perhaps not. if I could just get it going long enough to store off a dmesg to a USB stick or even floppy I could get a bit more... closure? it was Ben's machine, after all.

everything you wanted to know about railroading but were afraid to ask

Al Krug lays it down at http://www.alkrug.vcn.com/rrfacts/rrfacts.htm . braking, calculating traction, how to read signals, how not to break couplers, etc.

geezing with UUCP (social networking via store-and-forward)

UUCP, Unix-to-Unix CoPy, is a store-and-forward protocol used primarily for mail, news, and copying files. the loose newsgroup network known as USENET was implemented largely on UUCP. since the advent of accessible packet-switched networking (AKA the internet), UUCP is now only used in rare cases. I still wax fondly over it.

reprogramming WES

the WES DMUs are controlled by custom-programmed PLCs, specifically, those from KW software: http://www.kw-software.com/com/index1024.html . during testing, the DMUs had debug builds of the PLC controls, which allowed for tuning of parameters. once the parameters settled down, a release version was built, which has less tweakable knobs. I assume the IP and code for this went to US Railcar after Colorado Railcar went into liquidation.

grab bag of beautiful decay

revisiting mono

as stdio studios moves its location from the main floor to the newly remodeled attic of chez poofygoof, I have been contemplating what work I will soon be able to accomplish. getting creative juices flowing again is not something that can be forced, but having a regular reason for being in the studio and working the controls can help things along.

network solvers for the railroad industry

"The Railway Applications Section (RAS) provides a forum to bring together practitioners, consultants, and academics interested in applying operations research and management science (OR and MS) techniques to the railroad industry."

they're running a contest: http://informs-ras.org/Problem.htm the problem is to find an optimal fueling system for a provided rail network. the trains can't run out of fuel between yards, and the railroad wants to minimize cost. find the cheapest solution!
