Hypertext Glossary of Computer Science

This glossary was started in 1989 as a BERKOM infrastructure project service at the Technical University of Berlin, Process Computing Center (TUB PRZ[2]). The first online appearance was at the beginning of 1991 as an E-Mail-Service within the TUB PRZ with around 5000 entries.

The original format of the glossary is adapted for the use with tbl/eqn/nroff. Remnants of NROFF statements are only partially removed, an umlaut conversion into HTML &; notation is not currently done by the search script.

The first Web appearance was in February 1994 with >20000 entries at the Computer Science Department of the TUB. It had an one letter index (A to Z and special characters) first. The basic idea was that the hypertext glossary should be used only by mouse click. It failed. But at this time also the WAIS of the TUB CS worked, so there was no need for a specific search form.

At the end of BERKOM II in December 1995 the glossary included 26100 entries. The project owner - the DeTeBerkom as a subsidiary of the Telekom - was not interested to publish the glossary as their own. Even all attempts to publish the glossary as a book failed.

In the following time the WAIS and all other WWW services of the TUB CS broke down. But then the glossary was partly indexed by AltaVista, so there was still no urgent need for an own search service. Also the installing of WWW scripts at the TUB was factly forbidden.

In June 1998 I was informed that my CS account will be deleted, so the glossary returned to the original location - the PRZ. The account and glossary at the CS was deleted in August 1998. The PRZ account was blocked for access in September 1998 without any given reason. In October 1998 the first PERL/CGI searchable version of the glossary for web browsers was implemented. On a fast server its faster than the original shell script with nroff.

At the beginning of November 1998 the glossary hypertext was deleted from a TUB server for the second and last time. Thanks to the provider at February 2000 the script and the glossary moved to a more powerful server. The current address is http://www.surveyor.in-berlin.de/perls/.

The pages should be lynx enhanced, usable with any HTML-2 capable browser. The search form uses the GET method, so even older HTTP server should do it. If the script is called with nothing, it produces its own form. You have to specify one item at a time. Nevertheless this can consist of several words like Frame Relay, Token Ring, INFORMATION SUPERHIGHWAY etc. (You have to type - sorry for that! ;-)

You can specify if the search item should be a word/phrase within the whole text (Extended Search - might be a bit slower but its still faster than the original script). For the prevention of possible browser crashes the output is currently limited to 5000 entries. You can make your search Case Sensitive, too. Exact Match means that the entry should not be part of a word or a phrase - it is looked for with a space before and behind it. The first versions of the script had an error where queries with a '+' were searched for but not the correct result were returned (if any). Also there was an error when references included an '&'. These errors should be corrected, now. Please send any error or strange behaviour report to jd at surveyor.in-berlin.de!

The glossary had its 10th anniversary of creation in September 1999 with a bit less than 44000 entries. So some of its entries might be outdated or historic. But it is still growing.

It has about 60000 entries now, of which over 35000 are uniq, including current Internet Requests for Comments and Engineering Notes (RFC/IEN), Lecture Notes in Computer Science (LNCS), selected Emoticons, USENET-Jargon, various ITU recommendations, ISO standards, IATA airport codes and more.

"Computer Science related" includes terms and acronyms of telecommunication, statistics, electronics, mathematics, astronomy, astrophysics, aeronautics and more. To be forewarned: Its not the main goal of this glossary to be deathly serious in every case. This glossary is definately not supposed to be hosted on a MS-IIS! ;-D

The entries are normally sorted alphabetically, but partially numerically (as for RFC's etc.). For non-uniq entries the order is generally subjective. The mentioned referencing of RFC's within the Intro was a formerly switchable option, where a RFC is made retrievable by a link through an available online document. Within the search results since February 1999 any RFC is linked, independently of the fact whether it exists on the used server or not (previously at the Eunet Finland, now by FTP from the RFC Homepage). This is also true for the external linked man pages (at the DESY, introduced in May 2001, script-inclusion in October 2001).

If you prefer to use one of the top 5% acronym lists please use the FU-Acronym Index, the Peter Flynn WorldWideWeb Acronym and Abbreviation Server or the (Hypertext) FOLDOC (Free Online Dictionary Of Computing) by Denis Howe, once used by AltaVista for explaining computer terms. I use AltaVista for resolving acronyms for myself - you'll get funny and surprising alternatives, sometimes. You may also try whatis.com, SBF Glossary Virtual Thumbtabs and V.E.R.A.. One of the largest and oldest acronym lists in the net seemed to be StarBits at Centre de Donees Strasbourg. This service is discontinued, currently (with no given reason!).
