very good
"he did a bully job"; "a neat sports car"; "had a great time at the party"; "you look simply smashing"

cracking(n.)
(Chem.) the process of making lower molecular weight hydrocarbons from heavier hydrocarbons in petroleum, by exposure to heat and catalysts. It is used to convert heavier alkanes into gasoline, or to improve the octane number of an alkane mixture.

cracking(Noun)
The thermal decomposition of a substance, especially that of crude petroleum in order to produce petrol / gasoline.
cracking(Adverb)
Very, usually associated with praise.
It was a cracking good show.
cracking(Adjective)
Great
The race started at a cracking pace.
cracking(Adjective)
Enjoyable.
We had a cracking time.

Cracking
In petroleum geology and chemistry, cracking is the process whereby complex organic molecules such as kerogens or heavy hydrocarbons are broken down into simpler molecules such as light hydrocarbons, by the breaking of carbon-carbon bonds in the precursors. The rate of cracking and the end products are strongly dependent on the temperature and presence of catalysts. Cracking is the breakdown of a large alkane into smaller, more useful alkanes and alkenes. Simply put, hydrocarbon cracking is the process of breaking long-chain hydrocarbons into short ones. More loosely, outside the field of petroleum chemistry, the term "cracking" is used to describe any type of splitting of molecules under the influence of heat, catalysts and solvents, such as in processes of destructive distillation or pyrolysis. Fluid catalytic cracking produces a high yield of gasoline and LPG, while hydrocracking is a major source of jet fuel, diesel, naphtha, and LPG.

cracking
[very common] The act of breaking into a computer system; what a cracker does. Contrary to widespread myth, this does not usually involve some mysterious leap of hackerly brilliance, but rather persistence and the dogged repetition of a handful of fairly well-known tricks that exploit common weaknesses in the security of target systems. Accordingly, most crackers are incompetent as hackers. This entry used to say 'mediocre', but the spread of rootkit and other automated cracking has depressed the average level of skill among crackers.
