Programming variables are normally represented using multiple-character names. Single-character names are normally used to represent auxiliary variables (for example, a loop variable might be named i). Naming of variables is supported at different language levels and is part of the language syntax. M...

productivity have come from removing artificial barriers that have made the accidental tasks inordinately hard, such as severe hardware constraints, awkward programming languages, lack of machine time. How much of what software engineers now do is still devoted to the accidental, as opposed to the ...
Basically this structure can represent all the basic Redis data types like strings, lists, sets, sorted sets and so forth. The interesting thing is that it has a type field, so that it is possible to know what type a given object has, and a refcount, so that the same object can be ...
