i'm working on coldfusion dynamic website. website, there lot of cfcs , lot of functions within each cfc. would more efficient store instance of cfc in application variable, instance each cfc separately on each page load. for each page, @ 2 separate cfcs called. i'm interested in how performance effected when requests increase (stress). thanks! it depends. if cfcs in question singletons yes, it's wise instantiate them once , store them application scope. more experienced , application grows you'll find best tool manage object dependencies coldspring , creating object in onapplicationstart() best bet. if dealing transient objects you'd need create object per request.

possible duplicate: difference between throw , throw new exception() what point of having catch (exception) { throw; } what do? by itself, throw keyword re-raises exception caught catch statement above. handy if want rudimentary exception handling (perhaps compensating action rolling transaction) , rethrow exception calling method. this method has 1 significant advantage on catching exception in variable , throwing instance: preserves original call stack. if catch (exception ex) , throw ex, call stack start @ throw statement , lose method/line of original error.

i manipulate matrices (full or sparse) efficiently haskell's vector library. here matrix type import qualified data.vector.unboxed u import qualified data.vector v data link = full (v.vector (u.vector a)) | sparse (v.vector (u.vector (int,a))) type vector = u.vector as can see, matrix vector of unboxed vectors. now, dot product between vector , matrix. simple combining sum, zip , map. but if that, because i'm mapping through rows of matrix, result boxed vector, though unboxed. propagates output (field src) (full weights) = v.map (sum out) weights out = u.map output src sum s w = u.sum $ zipwithfull (*) w s propagates output (field src) (sparse weights) = v.map (sum out) weights out = u.map output src sum s w = u.sum $ zipwithsparse (*) w s zipwithfull = u.zipwith zipwithsparse f x y = u.map f' x f' (i,v) = f v (y u.! i) how can unboxed vector result efficiently ? i don't know field type is, d...

i'm adding 2 buttons ui, appear on top of 1 another. want them appear next each other. missing in code? m_btncrown = new imagebutton(this); m_btncrown.setimageresource(r.drawable.king_crown_thumb); m_btncrown.setalpha(100); relativelayout.layoutparams lp = new relativelayout.layoutparams( relativelayout.layoutparams.wrap_content, relativelayout.layoutparams.wrap_content); lp.addrule(relativelayout.align_parent_top); addcontentview(m_btncrown, lp); m_btnmonkey = new imagebutton(this); m_btnmonkey.setimageresource(r.drawable.monkey_small); m_btnmonkey.setalpha(100); lp = new relativelayout.layoutparams( relativelayout.layoutparams.wrap_content, relativelayout.layoutparams.wrap_content); lp.addrule(relativelayout.align_parent_top); lp.addrule(relativelayout.right_of, m_btncrown.getid()); addcontentview(m_btnmonkey, lp); i have written quick example demonstrate how create layout programmatically. public class codelayout extends activity { @overri...

i have added kml google earth use of button javascript. how can delete kml or clear kml's use of button? thanks to remove features can use following method. presumes 'ge' references plug-in object. function removeallfeatures() { var features = ge.getfeatures(); while (features.getlastchild() != null) { features.removechild(features.getlastchild()); } }

is possible override function based on number of parameters passing it? instance: function abc(name) { document.write ('my name is' + name); } function abc(name,friend) { document.write ('my name is' + name + 'and best friend\'s name is' + friend); } so in html if called abc(george) use first version of function, if called abc(george,john) use second version. there may other ways accomplish example used, i'm wondering if concept sound in javascript. javascript not support function overloading. you can, however: if (typeof friend === "undefined") { // } else { // else }

hey, i've written function copy variable type byte vector, whenever insert gets inserted in reverse. here's code. template <class type> void packet::copytobyte(type input, vector<uint8_t>&output) { copy((uint8_t*) &input, ((uint8_t*) &input) + sizeof(type), back_inserter(output)); } now whenever add example uint16_t value 0x2f1f gets inserted 1f 2f instead of expected 2f 1f. what doing wrong here ? regards, xeross if on little-endian machine (e.g., x86), bytes appear reversed (i.e., lower order bytes appear before higher order bytes). if want reverse order of bytes, can use std::reverse .

i have website when user zooms, lines no longer line in situations. unfortunately, don't have example show, know has lack of understanding of how zooming works. assume has things when zoom, pixel may end becoming 2 pixels because single old pixel gets drawn on half of 2 new pixels, depending on how zoom affects pixel orientation. are there workarounds dealing zooming on websites specified, pixel off noticeable? there 2 types of zoom. 1 increases fonts , other magnifies evenly. if issue second it's highly doubtful there can it. if it's first type @ how fonts expand , cases might want change relative units ems px (in general fonts specified in px don't zoom).

i in documentation , source code cannot figure out how return value type of boost bind functor. trying accomplish following: 35 template<typename t,size_t n, class f> 36 boost::array<typename f::value_type, n> make_array(t (&input)[n], f unary) { 37 boost::array<typename f::value_type, n> array; 38 std::transform(input, input + n, array.begin(), unary); 39 return array; 40 } where f can bind functor. above not work because functor not have value_type. matter, there standard interface unary/binary functor far return value. solution: should result_type . equivalent defined argument_type , first/second_argument_type binary functions thanks doh. nevermind, it's result_type rather value_type . should delete question?

my pyx depends upon native library how can pyximport.install() it? auto-build in pyxinstall doesn't know link native library, build fails... you can still export correct ldflags / cflags before doing pyximport.install() : from os import environ environ['cflags'] = '-i/path/to/my/custom/lib' environ['ldflags'] = '-lpath/to/my/custom/lib -lcustomlib' import pyximport pyximport.install() however, pyximport should used in debug case. prefer setup.py method !

i'm attempting eliminate left recursion cfg eliminating indirect recursion direct recursion algorithm shows. i'll using grammar: a = a | b c | b c | d d when i = 1 , , j = 1 looking @ replacing productions of form a -> r with: a -> δ 1 γ | δ 2 γ | .. | δ k γ so when @ a -> a matches, should replace with a -> a | b c a | b c | d d which im sure wrong can point me in right direction how replace productions when replacing production itself? note : also, i'm stuck on first rule have omitted others simplicity any appreciated [update]found close original greek symbols could. also, perhaps approaching in wrong direction. when i=1 , j=1 , a j -> a | b c | b c | d d, should using a j -> b c | d d if get: a -> b c | b c b c | d d | d d b c | b c | d d as eliminate recursion in production. better direction? this recipe: a → aα1 | ... | aαm | β1 | ... | βn should transformed to: a → β1 a' | ... | βn...
