BLOB
[acronym, Binary Large OBject] n. Used by database people to refer to any random large block of bits which needs to be stored in a database, such as a picture or sound file. The essential point about a BLOB is that it's an object you can't interpret within the database itself.
block
[from process scheduling terminology in OS theory] 1. vi. To delay or sit idle while waiting for something. "We're blocking until everyone gets here." Compare {busy-wait}. 2. `block on' vt. To block, waiting for (something). "Lunch is blocked on Phil's arrival."
block transfer computations
n. From the television series "Dr. Who", in which it referred to computations so fiendishly subtle and complex that they could not be performed by machines. Used to refer to any task that should be expressible as an algorithm in theory, but isn't.
blow an EPROM
/bloh *n ee'prom/ v. (alt. `blast an EPROM', `burn an EPROM') To program a read-only memory, e.g. for use with an embedded system. This term arises because the programming process for the Programmable Read-Only Memories (PROMs) that preceded present-day Erasable Programmable Read-Only Memories (EPROMs) involved intentionally blowing tiny electrical fuses on the chip. Thus, one was said to `blow' (or `blast') a PROM, and the terminology carried over even though the write process on EPROMs is nondestructive.
