The New Hacker's Dictionary

  1. delta

    1. [techspeak] A quantitative change, especially a small or incremental one (this use is general in physics and engineering). “I just doubled the speed of my program!” “What was the delta on program size?” “About 30 percent.” (He doubled the speed of his program, but increased its size by only 30 percent.) 2. [Unix] A diff, especially a diff stored under the set of version-control tools called SCCS (Source Code Control System) or RCS (Revision Control System). 3. n. A small quantity, but not as small as epsilon. The jargon usage of delta and epsilon stems from the traditional use of these letters in mathematics for very small numerical quantities, particularly in ‘epsilon-delta’ proofs in limit theory (as in the differential calculus). The term delta is often used, once epsilon has been mentioned, to mean a quantity that is slightly bigger than epsilon but still very small. “The cost isn't epsilon, but it's delta” means that the cost isn't totally negligible, but it is nevertheless very small. Common constructions include within delta of —, within epsilon of —: that is, ‘close to’ and ‘even closer to’.

Dictionary of Nautical Terms

  1. delta

    A name given by the Greeks to the alluvial tract inclosed between the bifurcating branches of the Nile and the sea-line. It is well known that rivers which deposit great quantities of matter, do also very often separate into two or more branches, previous to their discharge into the sea; thus forming triangular spaces, aptly called deltas from their resemblance to the Greek letter Δ. All deltas appear by their section to be formed of matter totally different from that of the adjacent country. They are the creation of the rivers themselves, which, having brought down with their floods vast quantities of mud and sand from the upper lands, deposit them in the lowest place, the sea; at whose margin, the current which has hitherto impelled them ceasing, they are deposited by the mere action of gravity. This is particularly illustrated on the western coast of Africa by the shoals off the Rio Grande, Rio Nunez, and others. The coast, as well as the embouchures of the rivers, exhibit a deposit of deep mud, and yet far at sea banks of clean siliceous sand arise.
