Java code that runs as part of a network service, typically an HTTP server and responds to requests from clients. For example, a client may need information from a database
a servlet can be written that receives the request, gets and processes the data as needed by the client and then returns the result to the client.Servlets are named after applets which are also written in Java but which run inside the JVM of a HTML browser on the client. Servlets and applets allow the server and client to be extended in a modular way by dynamically loading code which communicates with the main program via a standard programming interface. (http: // .

/net'ee-ket/ or /net'i-ket/ Network etiquette.The conventions of politeness recognised on Usenet and in mailing lists, such as not (cross-) posting to inappropriate groups and refraining from commercial advertising outside the biz groups.The most important rule of netiquette is "
Think before you post"
. If what you intend to post will not make a positive contribution to the newsgroup and be of interest to several readers, don't post it! Personal messages to one or two individuals should not be posted to newsgroups, use private e-mail instead.When following up an article, quote the minimum necessary to give some context to your reply and be careful to attribute the quote to the right person. If the article you are responding to was posted to several groups, edit the distribution ("
Newsgroups: "
) header to contain only those groups which are appropriate to your reply, especially if the original message was posted to one or more inappropriate groups in the first place.Re-read and edit your posting carefully before you post. Check the spelling and grammar. Keep your lines to less than 70 characters. Don't post test messages (except to test groups) - wait until you have something to say. When posting humorous or sarcastic comments, it is conventional to append a smiley, but don't overuse them.Before asking a question, read the messages already in the group and read the group's FAQ if it has one. When you do post a question, follow it with "
please reply by mail and I will post a summary if requested"
and make sure you DO post a summary if requested, or if only a few people were interested, send them a summary by mail. This avoids umpteen people posting the same answer to the group and umpteen others posting "
me too"
s.If you believe someone has violated netiquette, send them a message by _private e-mail_, DO NOT post a follow-up to the news. And be polite, they may not realise their mistake, they might be a beginner or may not even have been responsible for the "
- their account may have been used by someone else or their address forged.Be proud of your postings but don't post just to see your name in pixels. Remember: your future employer may be reading.{Netiquette for Usenet Site Administrators (http: // }.{"

1. A record of previous user inputs (e.g. to a command interpreter) which can be re-entered without re-typing them. The major improvement of the C shell (csh) over the Bourne shell (sh) was the addition of a command history. This was still inferior to the history mechanism on VMS which allowed you to recall previous commands as the current input line. You could then edit the command using cursor motion, insert and delete. These sort of history editing facilities are available under tcsh and GNU Emacs.2. {The history of computing (http: // }.3.

Chartered in 1746 as the College of New Jersey, Princeton was British North America's fourth college. First located in Elizabeth, then in Newark, the College moved to Princeton in 175
6. The College was housed in Nassau Hall, newly built on land donated by Nathaniel and Rebeckah FitzRandolph. Nassau Hall contained the entire College for nearly half a century. The College was officially renamed Princeton University in 1896
five years later in 1900 the Graduate School was established.Fully coeducational since 1969, Princeton now enrolls approximately 6, 400 students (4, 535 undergraduates and 1, 866 graduate students) . The ratio of full-time students to faculty members (in full-time equivalents) is eight to one.Today Princeton's main campus in Princeton Borough and Princeton Township consists of more than
5.5 million square feet of space in 160 buildings on 600 acres. The University's James Forrestal Campus in Plainsboro consists of one million square feet of space in four complexes on 340 acres.As Mercer County's largest private employer and one of the largest in the Mercer/Middlesex/Somerset County region, with approximately 4, 830 permanent employees - including more than 1, 000 faculty members - the University plays a major role in the educational, cultural, and economic life of the region.

(PPC) A RISC microprocessor designed to meet a standard which was jointly designed by Motorola, IBM, and Apple Computer (the PowerPC Alliance) . The PowerPC standard specifies a common {instruction set architecture} (ISA), allowing anyone to design and fabricate PowerPC processors, which will run the same code. The PowerPC architecture is based on the IBM POWER architecture, used in IBM's RS/6000 workstations. Currently IBM and Motorola are working on PowerPC chips.The PowerPC standard specifies both 32-bit and 64-bit data paths. Early implementations will be 32 bit
future higher-performance implementations will be 64 bit (e.g. PowerPC 601) . A PowerPC has 32 integer registers (32- or 64 bit) and 32 floating-point (IEEE standard 64 bit) floating-point registers.The POWER CPU chip and PowerPC have a (large) common core, but both have instructions that the other doesn't. The PowerPC offers the following features that POWER does not: Support for running in little-endian mode.Addition of single precision floating-point operations.Control of branch prediction direction.A hardware coherency model (not in Book I) .Some other floating-point instructions (some optional) .The real time clock (upper and lower) was replaced with the time base registers (upper and lower), which don't count in sec/ns (the decrementer also changed) .64-bit instruction operands, registers, etc. (in 64 bit processors) .See also PowerOpen, PowerPC Platform (PReP) .{IBM PPC info (http: // }.

1. (regexp, RE) One of the {wild card} patterns used by Unix utilities such as grep, sed and awk and editors such as vi and Emacs. These use conventions similar to but more elaborate than those described under glob. A regular expression is a sequence of characters with the following meanings: An ordinary character (not one of the special characters discussed below) matches that character.A backslash () followed by any special character matches the special character itself. The special characters are: "
matches any character except NEWLINE
(where the "
is called the "
Kleene star"
) matches zero or more occurrences of RE. If there is any choice, the longest leftmost matching string is chosen, in most regexp flavours."
at the beginning of an RE matches the start of a line and "
at the end of an RE matches the end of a line. [string] matches any one character in that string. If the first character of the string is a "
it matches any character (except NEWLINE, in most regexp flavours) and the remaining characters in the string. "
may be used to indicate a range of consecutive ASCII characters. (RE) matches whatever RE matches and, where n is a digit, matches whatever was matched by the RE between the nth (and its corresponding) earlier in the same RE. In many flavours (RE) is used instead of (RE) The concatenation of REs is a RE that matches the concatenation of the strings matched by each RE.<
matches the beginning of a word and >
matches the end of a word. In many flavours of regexp, >
and <
are are replaced by "
, the special character for "
word boundary"
.REm matches m occurences of RE. REm, matches m or more occurences of RE. REm, n matches between m and n occurences.The exact details of how regexp will work in a given application vary greatly from flavour to flavour. A comprehensive survey of regexp flavours is found in Friedl 1997 (see below) . [Jeffrey E.F. Friedl, "
{Mastering Regular Expressions (http: // }, O'Reilly, 199
2. Any description of a pattern composed from combinations of symbols and the three operators: Concatenation - pattern A concatenated with B matches a match for A followed by a match for B.Or - pattern A-or-B matches either a match for A or a match for B.Closure - zero or more matches for a pattern.The earliest form of regular expressions (and the term itself) were invented by mathematician Stephen Cole Kleene in the mid-1950s, as a notation to easily manipulate "

@@-party at'par`tee n. [from the @@-sign in an Internet address] (alt. @@-sign party at'si: n par`tee) A semi-closed party thrown for hackers at a science-fiction convention (esp. the annual World Science Fiction Convention or ``Worldcon'')
one must have a network address to get in, or at least be in company with someone who does. One of the most reliable opportunities for hackers to meet face to face with people who might otherwise be represented by mere phosphor dots on their screens. Compare boink. @comment ESR The first recorded @@-party was held at the Westercon (a U.S. western regional SF convention) over the July 4th weekend in 1980. It is not clear exactly when the canonical @@-party venue shifted to the Worldcon but it had certainly become established by Constellation in 198

tnanotechnology nan'-oh-tek-no`l*-jee n. A hypothetical fabrication technology in which objects are designed and built with the individual specification and placement of each separate atom. The first unequivocal nanofabrication experiments took place in 1990, for example with the deposition of individual xenon atoms on a nickel substrate to spell the logo of a certain very large computer company. Nanotechnology has been a hot topic in the hacker subculture ever since the term was coined by K. Eric Drexler in his book Engines of Creation (Anchor/Doubleday, ISBN 0-385-19973-2), where he predicted that nanotechnology could give rise to replicating assemblers, permitting an exponential growth of productivity and personal wealth (there's an authorized transcription at http: // .

tASCII as'kee n. [originally an acronym (American Standard Code for Information Interchange) but now merely conventional] The predominant character set encoding of present-day computers. The standard version uses 7 bits for each character, whereas most earlier codes (including early drafts of ASCII prior to June 1961) used fewer. This change allowed the inclusion of lowercase letters --- a major win --- but it did not provide for accented letters or any other letterforms not used in English (such as the German sharp-S @tex `ss' @end tex or the ae-ligature @tex `ae' @end tex which is a letter in, for example, Norwegian) . It could be worse, though. It could be much worse. See EBCDIC to understand how. A history of ASCII and its ancestors is at http: // Computers are much pickier and less flexible about spelling than humans
thus, hackers need to be very precise when talking about characters, and have developed a considerable amount of verbal shorthand for them. Every character has one or more names --- some formal, some concise, some silly. Common jargon names for ASCII characters are collected here. See also individual entries for bang, excl, open, ques, semi, shriek, splat, twiddle, and Yu-Shiang Whole Fish. This list derives from revision
2.3 of the Usenet ASCII pronunciation guide. Single characters are listed in ASCII order
character pairs are sorted in by first member. For each character, common names are given in rough order of popularity, followed by names that are reported but rarely seen
official ANSI/CCITT names are surrounded by brokets: <
. Square brackets mark the particularly silly names introduced by INTERCAL@. The abbreviations ``l/r'' and ``o/c'' stand for left/right and ``open/close'' respectively. Ordinary parentheticals provide some usage information. @include ascii.tex @sp 1 @noindent The pronunciation of # as pound is common in the U.S. but a bad idea
Commonwealth Hackish has its own, rather more apposite use of pound sign (confusingly, on British keyboards the pound graphic @tex `sterling' @end tex happens to replace #
thus Britishers sometimes call # on a U.S.-ASCII keyboard pound, compounding the American error) . The U.S. usage derives from an old-fashioned commercial practice of using a # suffix to tag pound weights on bills of lading. The character is usually pronounced hash outside the U.S@. There are more culture wars over the correct pronunciation of this character than any other, which has led to the ha ha only serious suggestion that it be pronounced `shibboleth' (see Judges 12: 6 in an Old Testament or Tanakh) . The uparrow name for circumflex and leftarrow name for underline are historical relics from archaic ASCII (the 1963 version), which had these graphics in those character positions rather than the modern punctuation characters. The swung dash or approximation sign is not quite the same as tilde in typeset material @tex (it looks like this: $sim$) @end tex but the ASCII tilde serves for both (compare angle brackets) . Some other common usages cause odd overlaps. The #, $, >
, and &
characters, for example, are all pronounced ``hex'' in different communities because various assemblers use them as a prefix tag for hexadecimal constants (in particular, # in many assembler-programming cultures, $ in the 6502 world, >
at Texas Instruments, and &
on the BBC Micro, Sinclair, and some Z80 machines) . See also splat. The inability of ASCII text to correctly represent any of the world's other major languages makes the designers' choice of 7 bits look more and more like a serious misfeature as the use of international networks continues to increase (see software rot) . Hardware and software from the U.S. still tends to embody the assumption that ASCII is the universal character set and that characters have 7 bits
this is a major irritant to people who want to use a character set suited to their own languages. Perversely, though, efforts to solve this problem by proliferating national character sets produce an evolutionary pressure to use a smaller subset common to all those in use. @comment This entry was based on the Usenet pronunciation guide, version
