Jargons of Info Tech industry

(A Love of Jargons)

Xah Lee, 2002 Feb

People in the computing field like to spur the use of spurious jargons.
The less educated they are, the more they like extraneous jargons, such
as in the Unix & Perl community. Unlike mathematicians, where in
mathematics there are no fewer jargons but each and every one are
absolutely necessary. For example, polytope, manifold,
injection/bijection/surjection, group/ring/field.., homological,
projective, pencil, bundle, lattice, affine, topology, isomorphism,
isometry, homeomorphism, aleph-0, fractal, supremum/infimum, simplex,
matrix, quaternions, derivative/integral, ... and so on. Each and every
one of these captures a concept, for which practical and theoretical
considerations made the terms a necessity. Often there are synonyms for
them because of historical developments, but never “jargons for
jargon's sake” because mathematicians hate bloats and irrelevance.

The jargon-soaked stupidity in computing field can be grouped into
classes. First of all, there are jargons for marketing purposes. Thus
you have Mac OS “X”, Windows “XP”, Sun OS to Solaris and the
versioning confusion of 4.x to 7 to 8 and also the so called
“Platform” instead of OS. One flagrant example is Sun Microsystem's
Java stuff. Oak, Java, JDK, JSDK, J2EE, J2SE enterprise edition or no,
from java 1.x to 1.2 == Java 2 now 1.3, JavaOne, JFC, Jini, JavaBeans,
entity Beans, Awk, Swing... fucking stupid Java and fuck Sun
Microsystems. This is just one example of Jargon hodgepodge of one
single commercial entity. Marketing jargons cannot be avoided in modern
society. They abound outside computing field too. The Jargons of
marketing came from business practice, and they can be excusable
because they are kinda a necessity or can be considered as a naturally
evolved strategy for attracting attention in a laissez-faire economy
system.

The other class of jargon stupidity is from computing practitioners, of
which the Unix/Perl community is exemplary. For example, the name Unix
& Perl themselves are good examples of buzzing jargons. Unix is
supposed to be opposed of Multics and hints on the offensive and
tasteless term eunuchs. PERL is cooked up to be “Practical Extraction
& Reporting Language” and for the precise marketing drama of being
also “Pathologically Eclectic Rubbish Lister”. These types of
jargons exudes juvenile humor. Cheesiness and low-taste is their
hall-mark. If you are familiar with unixism and perl programing, you'll
find tons and tons of such jargons embraced and verbalized by unix &
perl lovers. e.g. grep, glob, shell, pipe, man, regex, more, less,
tarball, shebang, Schwartzian Transform, croak, bless, interpolation,
TIMTOWTDI, DWIM, RFC, RTFM, I-ANAL, YMMV and so on.

There is another class of jargon moronicity, which i find them most
damaging to society, are jargons or spurious and vague terms used and
brandished about by programers that we see and hear daily among design
meetings, online tech group postings, or even in lots of computing
textbooks or tutorials. I think the reason for these, is that these
massive body of average programers usually don't have much knowledge of
significant mathematics, yet they are capable of technical thinking
that is not too abstract, thus you ends up with these people defining
or hatching terms a-dime-a-dozen that's vague, context dependent,
vacuous, and their commonality are often a result of sopho-morons
trying to sound big.

Here are some examples of the terms in question:

 • anonymous functions or lambda or lamba function
 • closure
 • exceptions (as in Java)
 • list, array, vector, aggregate
 • hash (or hash table) ← fantastically stupid
 • rehash (as in csh or tcsh)
 • regular expression (as in regex, grep, egrep, fgrep)
 • name space (as in Scheme vs Common Lisp debates)
 • depth first/breadth first (as in tree traversing.)
 • operator
 • operator overloading
 • polymorphism
 • inheritance
 • first class objects
 • pointers, references
 • tail recursion

My time is limited, so i'll just give a brief explanation of my thesis
on selective few of these examples among the umpteen.

In a branch of math called lambda calculus, in which much theories of
computation are based on, is the origin of the jargon _lambda function_
that is so frequently reciprocated by advanced programering donkeys. In
practice, a subroutine without side-effects is supposed to be what
“lambda function” means. Functional languages often can define them
without assigning them to some variable (name), therefore the
“function without side-effects” are also called “anonymous
functions”. One can see that these are two distinct concepts. If
mathematicians are designing computer languages, they would probably
just called such thing _pure functions_. The term conveys the meaning,
without the “lamba” abstruseness. (in fact, the mathematics
oriented language Mathematica refers to lambda function as pure
function, with the keyword Function.) Because most programers are
sopho-morons who are less capable of clear thinking but nevertheless
possess human vanity, we can see that they have not adopted the clear
and fitting term, but instead you see lambda function this and that
obfuscations dropping from their mouths constantly.

Now the term “closure” can and indeed have meant several things in
the computing field. The most common is for it to mean a subroutine
that holds some memory but without some disadvantages of modifying a
global variable. Usually such is a feature of a programing language.
When taken to extreme, we have the what's called Object Oriented
Programing methodology and languages. The other meaning of
“closure” i have seen in text books, is for it to indicate that the
things in the language is “closed” under the operations of the
language. For example, for some languages you can apply operations or
subroutines to any thing in the language. (These languages are often
what's called “dynamic typing” or “typeless”). However, in
other languages, things have types and cannot be passed around
subroutines or operators arbitrarily. One can see that the term
“closure” is quite vague in conveying its meaning. The term
nevertheless is very popular among talkative programers and dense
tutorials, precisely because it is vague and mysterious. These
pseudo-wit living zombies, never thought for a moment that they are
using a moronic term, mostly because they never clearly understand the
concepts behind the term among the contexts. One can particular see
this exhibition among Perl programers. (for an example of the
fantastically stupid write-up on closure by the Perl folks, see
“perldoc perlfaq7” and “perldoc perlref”.)

in the so-called “high-level” computing languages, there are often
data types that's some kind of a collection. The most illustrative is
LISt Processing language's lists. Essentially, the essential concept is
that the language can treat a collection of things as if it's a single
entity. As computer languages evolve, such collection entity feature
also diversified, from syntax to semantics to implementation. Thus,
beside lists, there are also terms like vector, array, matrix, tree,
hash/“hash table”/dictionary. Often each particular term is to
convey a particular implementation of collection so that it has certain
properties to facilitate specialized uses of such groupy. The Java
language has such groupy that can illustrate the point well. In Java,
there are these hierarchy of collection-type of things:

 Collection
   Set (AbstractSet, HashSet)
     SortedSet (TreeSet)
   List (AbstractList, LinkedList, Vector, ArrayList)

 Map (AbstractMap, HashMap, Hashtable)
   SortedMap (TreeMap)

The words without parenthesis are Java Interfaces, and ones in are
implementations. The interface hold a concept. The deeper the level,
the more specific or specialized. The implementation carry out
concepts. Different implementation gives different algorithmic
properties. Essentially, these hierarchies of Java show the potential
complexity and confusion around groupy entities in computer languages.
Now, among the programers we see daily, who never really thought out of
these things, will attach their own specific meaning to
list/array/vector/matrix/etc type of jargons in driveling and
arguments, oblivious to any thought of formalizing what the fuck they
are really talking about. (one may think from the above tree-diagram
that Java the language has at least put clear distinction to interface
and implementation, whereas in my opinion they are one fantastic fuck
up too, in many respects.)
