off by one

Off by one or OBO is a common error in computer program whereby a loop executes one time too few or too many. It occurs most commonly with complex vector or matrix scans.

Programmer 1: This program doesn't work. Take a look and see if there's anything wrong.
Programmer 2: Oh, this for loop is OBO. You aren't scanning the whole array.

channel one

A stupid "news" segment that they force you to watch in high school through the school tv's.

It consists of nothing but bullshit and it always goes to them talking about cancer or a lot of people dying to something "happy" so you forget about what you just heard.

It is the biggest load of bullshit since the OJ simpson trial.

"hey Zack, according to channel one we have cancer because we just watched a TV".

"hey zack this black guy is trying to avoid steryotypes, IT ISN"T WORKING"

"hey Zack, this is fucking bullshit who gives a shit about the "play of the week"

"hey zack these guys are fuck-offs"
