Running on the new server
This is a pointless post to see if the new server works.
Couple of links to things I’m reading
so I can find them regardless of my bookmarks.

And what’s a day without:

and also:
http://abstrusegoose.com/
Yeah, this hasn’t been touched in a while.
Doing other things elsewhere so I’ve left this to sit for a (long, long) while. But a server upgrade is going to have to happen soon and then I think it will be time to revive this.
ULF receiver and magnetic field measurement notes
Random notes for a project I may or may not do for an aurora detector system (the ULF part isn’t an obvious need, but the basic B field measurement is too ‘simple’ for what I need). Lot of stuff out there from whack-jobs, hopefully I avoid linking to any of those…

WTF…wordpress lost all my catagories!
No, not really. But if /tmp fills up that’s one of the symptoms.
Workaround to Framemaker bugs with transparent images
Transparent images by making them .eps in framemaker. (Framemaker has always had a serious design flaw in its ability to handle images, I guess the designers expected a white background on everything, the official excuse about text runaround makes no sense at all)
Nutone S-155 Fire Alarm
Removed this when painting the hallway, probably was installed mid 70’s. I’m sure there’s something clever I can do with he MALFUNCTION light.

Chatham MA beach panorama – using Hugin
only my second attempt at using Hugin. Done holding the camera so didn’t get enough overlap. Horizon didn’t come out straight. Also learned that moving people and waves are going to throw it off (yeah, obvious…)
Educational materials site
Good place to look for a range of primary/secondary lessons (not just science):
From which I found a link to here:
http://phet.colorado.edu/ which has various simulation programs available (java mostly)
