cardinality
<mathematics> The number of elements in a set. If two sets have the same
number of elements (i.e. there is a bijection between them) then they have the
same cardinality. A cardinality is thus an isomorphism class in the category of
sets.
aleph 0 is defined as the cardinality of the first infinite ordinal, omega (the
number of natural numbers).

getting plum projects and raises, and possibly one's job. E.g. "His Halloween

bug discovered by a customer might be a "CLM bug".

cargo cult programming
<programming, humour> A style of (incompetent) programming dominated by
ritual inclusion of code or program structures that serve no real purpose. A
cargo cult programmer will usually explain the extra code as a way of working
around some bug encountered in the past, but usually neither the bug nor the
reason the code apparently avoided the bug was ever fully understood (compare
shotgun debugging, voodoo programming).
The term "cargo cult" is a reference to aboriginal religions that grew up in the
South Pacific after World War II. The practices of these cults centre on
building elaborate mockups of aeroplanes and military style landing strips in
the hope of bringing the return of the godlike aeroplanes that brought such
marvelous cargo during the war. Hackish usage probably derives from Richard
Feynman's characterisation of certain practices as "cargo cult science" in his
book "Surely You're Joking, Mr. Feynman" (W. W. Norton & Co, New York 1985, ISBN
0393019217).

Carl Friedrich Gauss
<person> A German mathematician (1777  1855), one of all time greatest.
Gauss discovered the method of least squares and Gaussian elimination.
Gauss was something of a child prodigy; the most commonly told story relates
that when he was 10 his teacher, wanting a rest, told his class to add up all
the numbers from 1 to 100. Gauss did it in seconds, having noticed that
1+...+100 = 100+...+1 = (101+...+101)/2.
He did important work in almost every area of mathematics. Such eclecticism is
probably impossible today, since further progress in most areas of mathematics
requires much hard background study.
Some idea of the range of his work can be obtained by noting the many
mathematical terms with "Gauss" in their names. E.g. Gaussian elimination
(linear algebra); Gaussian primes (number theory); Gaussian distribution
(statistics); Gauss [unit] (electromagnetism); Gaussian curvature (differential
geometry); Gaussian quadrature (numerical analysis); GaussBonnet formula
(differential geometry); Gauss's identity (hypergeometric functions); Gauss sums
(number theory).
His favourite area of mathematics was number theory. He conjectured the Prime
Number Theorem, pioneered the theory of quadratic forms, proved the quadratic
reciprocity theorem, and much more.
He was "the first mathematician to use complex numbers in a really confident and
scientific way" (Hardy & Wright, chapter 12).
He nearly went into architecture rather than mathematics; what decided him on
mathematics was his proof, at age 18, of the startling theorem that a regular
Nsided polygon can be constructed with ruler and compasses if and only if N is
a power of 2 times a product of distinct Fermat primes.

Carrierless Amplitude/Phase Modulation
<communications> (CAP) A design of Asymmetric Digital Subscriber Line
transceiver developed by Bell Labs. CAP was the first ADSL design to be
commercially deployed and, as of August 1996, was installed on more lines than
any other.
CAP is a variation of Quadrature Amplitude Modulation, the modulation used by
most existing modems in 1997. With CAP, the three channels (POTS, downstream
data and upstream data) are supported by splitting the frequency spectrum. Voice
occupies the standard 04 Khz frequency band, followed by the upstream channel
and the highspeed downstream channel.

<security> (Or "wardialer") A program which uses a modem to dial a series
of phone numbers (say, from 7700000 to 7709999), and keeps a log of what phone
numbers answer with a modem carrier. The results of such a search were generally
used by people looking to engage in random mischief in random machines.
Since the 1980s, wardialers have generally fallen into disuse, partly because of
easily available "caller ID" technology, partly because fax machines are now in
wide use and would often be logged as a carrier by a wardialer, and partly
because there are so many new and more interesting venues for computerised
mischief these days.

Cartesian coordinates
<mathematics, graphics> (After Renee Descartes, French philosopher and
mathematician) A pair of numbers, (x, y), defining the position of a point in a
twodimensional space by its perpendicular projection onto two axes which are at
right angles to each other. x and y are also known as the abscissa and ordinate.
The idea can be generalised to any number of independent axes.
Compare polar coordinates.

Cartesian product
<mathematics> (After Renee Descartes, French philosper and mathematician)
The Cartesian product of two sets A and B is the set
A x B = {(a, b)  a in A, b in B}.
I.e. the product set contains all possible combinations of one element
from each set. The idea can be extended to products
of any number of sets.
If we consider the elements in sets A and B as points along perpendicular axes
in a twodimensional space then the elements of the product are the "Cartesian
coordinates" of points in that space.
