Software design and development

New subject available for schools in sydney, unfortunatley lots of cases of really crap teachers who don't know visual basic, leaving the very small majority who can use a computer prior to learn them selves

Teacher: OK class today! im going to teach you that you are supposed ot use IF,THEN,ELSE,ENDIF statement 4 times in one psuedoprogram!

SDF

Used in personal ads for Safe and Disease Free. Safe meaning practices safe sex.

Things are pretty bad and I know the only satisfaction i'll get is sex. There's no calming me down when I get this way. NSA tonight won't deal with my drama. Guess that leaves you.. haha.

Mail me with your pics and please be SDF.

SDK is a abbreviation for some dumb skank. General term for a vapid, almost completely interchangeable, bitch.

That sdk is printing off 400 front phone books for the pledges in her sorority.
