when rendering 3d rectangles (i.e. rectangles in 3d space), of course, specified list of vertexes 2 triangles. however, representation contains lot of extraneous information gets tiresome code multiple times. i'd create "rectangle" object allow me specify texture, size, position, , orientation in space , export list of vertexes (and indexes), i'm not sure of best way it. should specify position of lower left corner (pre-rotation), or center of rectangle? how should specify orientation, vector containing rotation angles? such simple , standard requirement i'm sure people have thought before, can't find on site or elsewhere on subject. plan use these objects lot, primary goal (apart performance) ease of use rather internal representation. wouldn't hard me code first thing can think of, don't want miss , make unnecessarily difficult. so, how should represent rectangle object? opinions welcome, sources helpful. edit: if helps, believe i'd using...

i want know difference between drain , release in memory management..please me suitable example. in garbage collected environment, release no-op. nsautoreleasepool therefore provides drain method in reference-counted environment behaves same calling release , in garbage collected environment triggers garbage collection (if memory allocated since last collection greater current threshold). typically, therefore, should use drain rather release dispose of autorelease pool. source: http://developer.apple.com/library/mac/#documentation/cocoa/conceptual/memorymgmt/articles/mmautoreleasepools.html

is there similar r's findinterval (or cut ) in sas, in iml? i'm converting r program of mine monte carlo simulations iml, , uses findinterval convert numbers random number generator output state. can write in iml replace it, it's terribly slow compared original. because findinterval takes advantage of compiled c code; there similar can use in sas? are breaks uniform (equal probability) or not? uniform breaks, can use ceil(k*u) u vector or random uniform numbers. example, if want 10 observations randomly assigned numbers 1-4 equal probability, can say y = ceil(4*ranuni(j(10,1))); or, if want use newer random number generator, u = j(10,1); /** allocate **/ call randgen(u, "uniform"); /** fill u[0,1] **/ y = ceil(4*u); for unequal probability, use "table" distribution. example, p = {0.1 0.5 0.2 0.2}; /** 4 categories given probabilities **/ y = j(10, 1); call randgen(y, "table", p); /** fills 1-4 probability p **/ yo...

a basic question here. can see going on can't understand why work way. a = false; var k = function() { console.log(a); var = true console.log(a); }(); i expect log read "false, true" "a" undefined @ first. can please elaborate why this. ps. i'm not looking answer telling me should do, i'm looking explanation of inner workings of piece of javascript. thanks in advance this because javascript scoping works called "hoisting". when parser reads javascript function, goes through , finds variables defined in scope (using var ) keyword (remember type of scope in javascript function scope). puts them @ top of function. so parser interprets code follows: a = false; var k = (function() { var a; console.log(a); = true console.log(a); }()); (nb have corrected function call doesn't return syntax error.) obviously sets a undefined before first console.log . as mdc docs say : every defi...

i have "log-queries-not-using-indexes" enabled in mysql. have 1 query being logged mysql such i.e. query not using indexes. thing query uses e.g. category '%fashion%' and if remove or change to category = 'fashion' then says using indexes. so when using in our query, mysql log not using indexes no matter what? thanks using clause %fashion% never use regular index. need full-text index if want kind of search. remember varchar indexes on first part of string. so, if searching ocurrence of fashion on any part of string, index offer no improve performance since need search every single string. however, if search first part this: select * table field 'fashion%' then index used , helpful.

i'm looking simple way pass messages 1 process (perl script, short-lived) (python script, long-running) - both processes local same machine. i've done research, i've found either on head or seemed unnecessarily complex - leaving me bit lost , confused. i imagine minimal example following: # listener.py class listener: def __init__(self, port) self.port = port def on_message(self, msg): print "%s: %s" % (timestamp, msg) recipient = listener(1234) # sender.pl sub send_message { ($msg, $port) = @_; # ... } send_message("hello world", 1234); any pointers on how solve and/or read on appreciated! in general interested in sockets. place needed rough information documentation of io::socket::inet or more basic socket-stuff in perl perldoc perlipc

in .h, have variable, texture ** skyboxtextures . assign texture pointers in 1 method, , use them right away: texture *skt[] = { tleft, tright, tfront, tback, tup, tdown }; skyboxtextures = skt; for(int = 0; < 6; i++) { skyboxtextures[i]->load(); } then later in method try use textures again. texture *skt[] = skyboxtextures; // render front quad skyboxtextures[0]->activate(); this issue cannot access objects more. not compile because of error: error c2440: 'initializing' : cannot convert 'texture **' 'texture *[]' if comment out line texture *skt[] = skyboxtextures; , invalid texture pointers. then later in method try use textures again. you cannot that. converting array pointer it's first element 1 way process. while array still array compiler has information size of array available @ compile time. once it's pointer, compiler no longer has information. you either have reference skt...

heya, quick question. i've got multiple instances on ec2 load balancer between them. use svn app used push live env. @ will. with multiple ec2's, how push codebase of them @ once? thoughts/links appreciated. there few different ways this. if using elastic load balancers write script that: removes machine pool updates svn repository re-adds machine pool repeats additional machines you fancy , remove 1 machine, update it, remove other machines , update them, if you're concerned consistency. if using custom load balancing application look capistrano . don't need use ruby/rake -- can write custom cap files can parallel deploys.

i have changed x axis dateasordinal , improve label format. handle xaxis.scaleformatevent this: private function onxscaleformatevent(byval pane graphpane, byval axis axis, byval val double, byval index integer) string dim result string = "" if val < pricebars.count dim time date = date.fromoadate(pricebars(val).x) result = [string].format("{0:d2}{1}{2:d2}", time.hour, ":", time.minute) end if return result end function how can make labels print every whole 30 minutes? or every 2 hours in image below? believe still need reference bar x-values, because need plot multiple days continuously, hours each day, image shows; 09:00-23:00. http://i53.tinypic.com/2jcwknd.png i think, do: chart.graphpane.xaxis.scale.majorstepauto = false chart.graphpane.xaxis.scale.majorunit = dateunit.minute chart.graphpane.xaxis.scale.majorstep = 30 chart.graphpane.xaxis.scale.basetic = 0

i have following code containing template function. when calling function second parameter being enum: in cases finds template specialization , in cases not. i had verified enums same enums in both cases (e.g there no redefinitions) , other parameters have correct values, found 1 compilation done -winline set (i did not try changing yet) else at? class { public: template <typename t> int f(uint32_t id, t const& t, bool cond); ... }; template <typename t> int a::f(uint32_t id, t const& t, bool cond) { ... } template <> inline int a::f<int>(uint32_t, int const& t, bool cond) { .... } for starters, typically, it's inadvisable use template specialization way of overloading template function. template specializations interact poorly function overloading , have pretty arcane rules dictating when they're chosen, , in general it's considered better provide regular function overload specialize function tem...
