What do variable names mean (in Python and elsewhere)?

What are variables?

In many languages, variables are just labels for storage locations,for a spot in memory. This ranges from pure machine level storage, inlanguages like assembler, up through storage locations augmented withsize and type information, such as in C, all the way to Perl, where the'storage locations' are actually fairly abstract. But they're stillthere, even in Perl, partly because it's a comforting way to think aboutit: variables are where you put things .

Public interfaces and Solaris 9 patchadd exit codes

A commenter on an earlier entry noted that patchadd 's exit codes are apparently not documented because they'reconsidered an internal implementation detail that might change at somepoint. Unfortunately this is bogus logic.
