-
we're working on flash cs4 project main .fla file has ballooned in size , 'publish' taking forever. suspect large amount of size (and @ least of compile time) due quantity of audio symbols in library. i love remove unnecessary bloat .fla file. i've experimented removing audio symbol library , using [embed] metadata tag instead, so: [embed(source="audio/music/endoflevelditty.mp3")] public var endoflevelditty:class the resulting published file works perfectly, there problem. our game uses preloader on first frame of timeline, other classes need exported in frame 2 (as set in publish settings > actionscript 3.0 settings ). size report begins this: frame # frame bytes total bytes scene ------- ----------- ----------- ---------------- 1 284515 284515 scene 1 2 5485305 5769820 (as 3.0 classes export frame) however, if use [embed] tag on small sound, size report now: frame # ...

internationalization - Multilanguage document in Latex -

how prepare latex document translation... need 1 multilanguage document. should like: \section{pl:costam; en:something} then i'd render in polish or english... if else fails, can go more basic, insultingly dumb approach: \newcommand{\dumblang}[2]{{#1}} this defines command 2 arguments ( [2] ) , spits out first ( {#1} ). so example can have... \usepackage[\dumblang{english}{italian}]{babel} %snip \section{\dumblang{introduction}{introduzione}} \dumblang{your introduction goes here!}{scrivi qua la tua introduzione!} ...and when want document in italian, can change \dumblang to: \newcommand{\dumblang}[2]{{#2}}

i'm new actionscript (v3), 20 years c++ though, , i'm trying head around of performance caveats i'm reading. i checked out site: http://www.nbilyk.com/optimizing-actionscript-3 and scared death of 'code' section saying actionscript has dynamic lookup when trying find static methods in package. point being inefficient put util-type functions (typically math functions) in own package static functions, because has lookup namespace , method dynamically each time call it. is true? it's not expected, coming c++, , changes how structure code , libraries. wonder if it's better have singleton util library new()'d once, containing methods normal public methods, have them static in package. are there other obvious gotchas this? cheers, shane yes true. calling static functions outside class slow. tested myself, on 10,000 iterations 220ms static vs 160ms calling function on instance. other tips avoid adobe compiler. have started using h...

is following possible in python: >>> vars = {'a': 5} >>> makevars(vars) >>> print 5 so, makevars converts dictionary variables. (what called in general?) it's possible, sometimes, it's bad idea. in spite of name, variables themselves should not variable. they're part of code, part of logic. trying 'replace' local variables way makes code inefficient (since python has drop of optimizations), buggy (since can accidentally replace didn't expect), hard debug (since can't see what's going on) , plain unreadable. having 'dynamic values' dicts , lists , other containers for.

data structures - Should I use structs in C++? -

-
the difference between struct , class small in c++, struct members per default public , class members per default private. however, still use structs whenever need pure data structures, instance: struct rectangle { int width; int height; }; i find convenient work with: rectangle r; r.width = 20; r.height = 10; however, data structures procedural programming, , i'm doing object oriented programming. bad idea introduce concept oo? no. if makes sense use struct somewhere, why complicate things using else isn't meant fit purpose ? in projects, tend use struct simple "structures" need hold trivial data. if data structure needs have "smartness" , hidden fields/methods, becomes class.
