51 <explanation language="en">
53 a technique used in charging;
54 for pre-paid subscribers the standard way to charge services is online
55 – subscriber's balance is checked in the billing system and if sufficient, the service (e.g. sending a SMS) is provided, otherwise the service is denied;
56 if the billing system is not currently available (so we can't say if the subscriber's balance is high enough), we can provide the service anyway and try to charge it later;
57 this feature requires saving state (transactions which weren't charged yet) in some persitent storage (CDR files, SQL database etc.)
58 and can be done at the billing gateway or directly at system like SMSC

155 a kind of electronic communication between two persons or a group chat;
156 compared to e-mail, IM messages are short (few words, sentence) and the other side is expected (depending on his/her online status) to read and respond it immediately;
157 compared to SMS, IM messages are cheap – typically free of charge;
158 important IM feature is presence – the sender knows current status of the recipient: online, offline, away, busy etc.;
159 IM is rooted in the computer world but nowadays it is often used also on mobile phones as an alternative to (expensive) SMS – in such case it is called OTT and requires mobile Internet connectivity;
160 IM messages are usually transferred over an TCP/IP protocol – good example is Jabber/XMPP which is free and open protocol for IM and presence based on XML

269 <term abbreviation="MUA" completeForm="mail user agent" language="en"/>
270 <explanation language="en">
272 an e-mail client – a software used for managing user's e-mail;
273 because the MUA (like most client software) runs only when user needs it,
274 the messages from the Internet are received by a remote MTA over the SMTP protocol,
275 then delivered using an MDA into user's remote mailbox,
276 from which they are obtained by the MUA using POP3 or IMAP4 protocols;
277 when sending an e-mail, the MUA composes the message in RFC 5322 format and then submits it using the SMTP protocol to a MTA or MSA server;

327 a software component that fetches e-mails from remote server (over POP3 or IMAP4 protocol)
328 and then passes them to the MDA for local storage, or over SMTP to an MTA, or directly delivers it to the mailbox, or prints to standard output etc.;
329 implements pull (not push) approach: fetches messages periodically (or on user's demand)
330 instead of waiting for incoming messages and receiving them immediatelly when they emerge (like MTA does);
331 examples of MRA: fetchmail, getmail
338 <term abbreviation="" completeForm="sieve" language="en"/>
339 <explanation language="en">
341 a standardized language for describing e-mail filters;
342 the MDA can apply system-wide or user-defined filters on incoming messages;
343 a filter has conditions (connected by logical operators: AND, OR…) like „message header contains value X“
344 and actions that will be done with the message like „file into folder X“ or „add flag/label X“ or „redirect message to some.address@example.com“ or „discard message“;
345 filters are executed on the server where MDA resides,
346 so they are independent of the MUA currently used by the user
347 and works even if the user is offline (useful for OOTO messages when the user is on vacation)
354 <term abbreviation="OOTO" completeForm="out of the office" language="en"/>
355 <explanation language="en">

398 in case of UTF-8 it is from 1 byte up to 6 bytes per character;

1487 „someone who enjoys playful cleverness, especially in programming but other media are also possible“
1489 ESR - http://www.catb.org/~esr/jargon/html/H/hacker.html
1490 [originally, someone who makes furniture with an axe]
1491 1. A person who enjoys exploring the details of programmable systems and how to stretch their capabilities, as opposed to most users, who prefer to learn only the minimum necessary. RFC1392, the Internet Users' Glossary, usefully amplifies this as: A person who delights in having an intimate understanding of the internal workings of a system, computers and computer networks in particular.
1492 2. One who programs enthusiastically (even obsessively) or who enjoys programming rather than just theorizing about programming.
1493 3. A person capable of appreciating hack value.
1494 4. A person who is good at programming quickly.
1495 5. An expert at a particular program, or one who frequently does work using it or on it; as in ‘a Unix hacker’. (Definitions 1 through 5 are correlated, and people who fit them congregate.)
1496 6. An expert or enthusiast of any kind. One might be an astronomy hacker, for example.
1497 7. One who enjoys the intellectual challenge of creatively overcoming or circumventing limitations.
1498 8. [deprecated] A malicious meddler who tries to discover sensitive information by poking around. Hence password hacker, network hacker. The correct term for this sense is cracker.
1499 The term ‘hacker’ also tends to connote membership in the global community defined by the net (see the network. For discussion of some of the basics of this culture, see the How To Become A Hacker FAQ. It also implies that the person described is seen to subscribe to some version of the hacker ethic (see hacker ethic).
1500 It is better to be described as a hacker by others than to describe oneself that way. Hackers consider themselves something of an elite (a meritocracy based on ability), though one to which new members are gladly welcome. There is thus a certain ego satisfaction to be had in identifying yourself as a hacker (but if you claim to be one and are not, you'll quickly be labeled bogus). See also geek, wannabee.
1501 This term seems to have been first adopted as a badge in the 1960s by the hacker culture surrounding TMRC and the MIT AI Lab. We have a report that it was used in a sense close to this entry's by teenage radio hams and electronics tinkerers in the mid-1950s.
