Here are the complete 1988-vintage Sun manuals “Using NROFF and TROFF” and “Formatting Documents” scanned just for you. I’d scanned these in 2000, and they’d sat on a forgotten archive volume since then.
(if you need to get your troff on, go to Ralph’s troff.org.)
We live in a Scarborough neighbourhood, so that means that people use the side door. Front door’s for people who know no better. So we need a Side Door sign to guide the unschooled.
On the left is one I just printed. The one on the right — same printer (HP Photosmart C5180), same paper — has been taped to the glass on our front-facing screen door since December 2007, in full sunlight. It’s barely legible. (And yes, it has slightly different fonts/layout; the original was done on a PC in OpenOffice, the replacement in LibreOffice on a Mac.)
So whenever an inkjet crows about “Archival Inks!”, remember: four years to fade to white. Do you need your images to last longer?
After my solar course, I’ve been messing about with the UO SRML: Sun chart program. It shows sun angles and day lengths throughout the year.
Toronto: where I live
Glasgow: where I'm from. Not much sun there, but looong summer days
Phoenix, AZ is pretty sunny
I think I'd freak out if I lived at the equator: every day is nearly the same length!
Mombasa, Kenya: point your modules north!
Not much sun in far north Alert; sometimes, the sun doesn't set — sometimes it doesn't rise
I don't think I'd mind living in Glasgow — Glasgow, Guyana, that is.
You can still buy these here: WISE – Nuclear issues information service. I just ordered a bunch.
