 			<text>

 				a technique used in charging;

 				for pre-paid subscribers the standard way to charge services is online

 				– 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;

 				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;

 				this feature requires saving state (transactions which weren't charged yet) in some persitent storage (CDR files, SQL database etc.)

 				and can be done at the billing gateway or directly at system like SMSC

 			<text>

 				a kind of electronic communication between two persons or a group chat;

 				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;

 				compared to SMS, IM messages are cheap – typically free of charge;

 				important IM feature is presence – the sender knows current status of the recipient: online, offline, away, busy etc.;

 				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;

 				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

 				he might not want expose his identity (MSISDN or IMSI);

 				use case:

 					everyone will have one vote,

 					but the owner of the survey will not know the opinion of particular subscibers

 					because of missing their real IDs

 			<text>

 				hacker is an interrogative person interested in internal principles of things;

 				often it is a software developer or a system administrator but hacking is also possible outside the digital world;

 				hacking is the activity of these people – usually

 					improving a software by adding new features

 					or discovering secrets in existing software or hardware systems

 					or running extraordinary configurations or combinations of components;

 				hack is the product of their work – e.g. improved computer program or piece of hardware;

 				<!-- hack can mean also the insctructions how to do it; -->

 				don't confuse with „cracker“

 			<!--

 				RMS - https://www.gnu.org/philosophy/rms-hack.html

 				„someone who enjoys playful cleverness, especially in programming but other media are also possible“

 				ESR - http://www.catb.org/~esr/jargon/html/H/hacker.html

 				[originally, someone who makes furniture with an axe] 

 				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.

 				2. One who programs enthusiastically (even obsessively) or who enjoys programming rather than just theorizing about programming. 

 				3. A person capable of appreciating hack value. 

 				4. A person who is good at programming quickly. 

 				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.) 

 				6. An expert or enthusiast of any kind. One might be an astronomy hacker, for example. 

 				7. One who enjoys the intellectual challenge of creatively overcoming or circumventing limitations. 

 				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.

 				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).

 				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.

 				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.

 				RFC 1392 - https://tools.ietf.org/html/rfc1392

 				A person who delights in having an intimate understanding of the

 				internal workings of a system, computers and computer networks in

 				particular.  The term is often misused in a pejorative context,

 				where "cracker" would be the correct term.  See also: cracker.
