Ob- : Obligatory. A piece of netiquette acknowledging that the author has been straying from the newsgroup's charter topic. For example, if a posting in alt.sex is a response to a part of someone else's posting that has nothing particularly to do with sex, the author may append ‘ObSex’ (or ‘Obsex’) and toss off a question or vignette about some unusual erotic act. It is considered a sign of great winnitude when one's Obs are more interesting than other people's whole postings.

Obfuscated C Contest : (in full, the ‘International Obfuscated C Code Contest’, or IOCCC) An annual contest run since 1984 over Usenet by Landon Curt Noll and friends. The overall winner is whoever produces the most unreadable, creative, and bizarre (but working) C program; various other prizes are awarded at the judges'whim. C's terse syntax and macro-preprocessor facilities give contestants a lot of maneuvering room. The winning programs often manage to be simultaneously (a) funny, (b) breathtaking works of art, and (c) horrible examples of how not[/b] to code in C.This relatively short and sweet entry might help convey the flavor of obfuscated C: /* * HELLO WORLD program * by Jack Applin and Robert Heckendorn, 1985 * (Note: depends on being able to modify elements of argv[], * which is not guaranteed by ANSI and often not possible.) */ main(v,c)char**c;{for(v[c++]='Hello, world!
)'; (!!c)[*c]&&(v--||--c&&execlp(*c,*c,c[!!c]+!!c,!c)); **c=!c)write(!!*c,*c,!!**c);} Here's another good one: /* * Program to compute an approximation of pi * by Brian Westley, 1988 * (requires pcc macro concatenation; try gcc -traditional-cpp) */ #define _ -F<00||--F-OO--; int F=00,OO=00; main(){F_OO();printf('%1.3f
',4.*-F/OO/OO);}F_OO() { _-_-_-_ _-_-_-_-_-_-_-_-_ _-_-_-_-_-_-_-_-_-_-_-_ _-_-_-_-_-_-_-_-_-_-_-_-_-_ _-_-_-_-_-_-_-_-_-_-_-_-_-_-_ _-_-_-_-_-_-_-_-_-_-_-_-_-_-_ _-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_ _-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_ _-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_ _-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_ _-_-_-_-_-_-_-_-_-_-_-_-_-_-_ _-_-_-_-_-_-_-_-_-_-_-_-_-_-_ _-_-_-_-_-_-_-_-_-_-_-_-_-_ _-_-_-_-_-_-_-_-_-_-_-_ _-_-_-_-_-_-_-_ _-_-_-_ } Note that this program works by computing its own area. For more digits, write a bigger program. See also hello world .The IOCCC has an official home page at http://www.ioccc.org/ .

Objectionable-C : Hackish take on Objective-C, the name of an object-oriented dialect of C in competition with the better-known C++ (it is used to write native applications on the NeXT machine). Objectionable-C uses a Smalltalk-like syntax, but lacks the flexibility of Smalltalk method calls, and (like many such efforts) comes frustratingly close to attaining the Right Thing without actually doing so.

Obscure : Used in an exaggeration of its normal meaning, to imply total incomprehensibility. The reason for that last crash is obscure. The find 1 command's syntax is obscure! The phrase moderately obscure implies that something could be figured out but probably isn't worth the trouble. The construction is the preferred emphatic form.

Octal forty : Hackish way of saying I'm drawing a blank. Octal 40 is the ASCII space character, 0100000; by an odd coincidence, hex 40 (01000000) is the EBCDIC space character. See wall .

Off the trolley : Describes the behavior of a program that malfunctions and goes catatonic, but doesn't actually crash or abort. See glitch, bug, deep space, wedged . This term is much older than computing, and is (uncommon) slang elsewhere. A trolley is the small wheel that trolls, or runs against, the heavy wire that carries the current to run a streetcar. It's at the end of the long pole (the trolley pole) that reaches from the roof of the streetcar to the overhead line. When the trolley stops making contact with the wire (from passing through a switch, going over bumpy track, or whatever), the streetcar comes to a halt, (usually) without crashing. The streetcar is then said to be off the trolley, or off the wire. Later on, trolley came to mean the streetcar itself. Since streetcars became common in the 1890s, the term is more than 100 years old. Nowadays, trolleys are only seen on historic streetcars, since modern streetcars use pantographs to contact the wire.

Off-by-one error : [common] Exceedingly common error induced in many ways, such as by starting at 0 when you should have started at 1 or vice-versa, or by writing < N instead of <= N or vice-versa. Also applied to giving something to the person next to the one who should have gotten it. Often confounded with fencepost error, which is properly a particular subtype of it.

Offline : Not now or not here. Let's take this discussion offline. Specifically used on Usenet to suggest that a discussion be moved off a public newsgroup to email.

Ogg : [CMU] 1. In the multi-player space combat game Netrek, to execute kamikaze attacks against enemy ships which are carrying armies or occupying strategic positions. Named during a game in which one of the players repeatedly used the tactic while playing Orion ship G, showing up in the player list as Og. This trick has been roundly denounced by those who would return to the good old days when the tactic of dogfighting was dominant, but as Sun Tzu wrote, What is of supreme importance in war is to attack the enemy's strategy, not his tactics. However, the traditional answer to the newbie question What does ogg mean? is just Pick up some armies and I'll show you. 2. In other games, to forcefully attack an opponent with the expectation that the resources expended will be renewed faster than the opponent will be able to regain his previous advantage. Taken more seriously as a tactic since it has gained a simple name. 3. To do anything forcefully, possibly without consideration of the drain on future resources. I guess I'd better go ogg the problem set that's due tomorrow. Whoops! I looked down at the map for a sec and almost ogged that oncoming car.
