I just saw an ad for the classic Rankin/Bass "Rudolph the Red Nosed Reindeer", but it's Now in Hi-Def. But.... if the original material was shot in our glorious granular lo-fi kinescoping that I grew up with, won't Hi-Def just give you glorious granular lo-fi kinescoping with more pixels per inch?

Also, lunch involves the 'heart smart' marinara.... with four strips of bacon.

I *must* be reading this wrong.

"College Algebra", in my transcript analysis, is listed with code CSUX00B4.
According to documentation, CSUX indicates classes that can be used to satisfy a CSU 'Breadth' requirement, because De Anza doesn't have an equivalent course.
