1. historicalcomputingA container for holding chad (“small punched-out pieces of paper”) from paper tape or punch cards used with teleprinters, early computers, and other machines.

   The lost bits fall into a container called a bit bucket. They are emptied periodically and the collected bits are used for confetti at weddings, parties, and other festive occasions.

   Synonyms: chad box

2. broadlyhumorousslangcomputingAn imaginary domain that accepts lost, discarded, or useless digital data that does not reach its intended destination, such as data lost in transmission or due to errors; the notional resting place of lost or missing digital information.

   bit bucket – the term for a routine or circuit that accepts binary signals and produces no output. Bit buckets are used for testing and to stand in for routines or circuits that have not been implemented at that particular point.

   Inside the computer, every time a byte moves from one component to another the hardware performs a parity check by counting the number of ones. [...] But let's say a power surge or some other line noise is picked up by the computer and the byte is scrambled. [...] The errant byte, having failed the parity test, is unceremoniously dumped into the bit bucket, the computer's wastepaper basket.

   Fortunately, "RTM" [Robert Tappan Morris] was not out to deliberately cause damage. What would have happened if he had been? Millions of dollars in time and research data gone into the bit-bucket?

   An alternative is for the automated spacecraft to assume that tracking is always available and to have the spacecraft take its data and return it accepting that some fraction of the time communication will in fact not be available. Science data would then go into the "bit bucket." Since current spacecraft are complex and expensive, the latter solution is rarely used (intentionally!) today.

   When a packet arrives, the first thing that is done is a cyclic redundancy check [...]. If the CRC does not match the one carried in the frame, then the packet is destroyed (sent to the "Bit Bucket" in Figure 16.1).

   When the program is pressed into heavier duty it simply can't hold the entire list in memory, so someone else has to "open up the code" and perform major, instead of minor, surgery. This only increases the chances that the program will be bitbucketed rather than updated.
