- Brute Force and Ignorance - programming jargon for relying on raw computing power. For example, an algorithm that uses BFI might search through all possible options to find the single best option, whereas a more sophisticated algorithm might deduce the best option using a set of rules. BFI based algorithms tend to be simpler, and can under some circumstances be faster.
- Brute Force and Ignorance - pre-dates computers, and refers to a 'sledge-hammer to crack a nut' type of approach. Implies an approach with a lack of subtlety or sophistication, instead, implies the use of raw strength or power.
- Brace For Impact - Common warning from U.S. military units to infer a warning to brace themselves, mainly because of an immediate threat. May either be pronounced as "B-F-I" in the letter order, or as "Bee-fi" in short.
