does git store text compressed gzip binary files or can tell it's text , store changes between updates files? git not attempt binary files. in fact, doesn't attempt text files. doesn't store updates @ all. store full contents of every single file, delta-compression across entire object store. data that's stored on-disk in fact updates (hence "delta-compression"), git sees full files. that said, no, git not attempt decompress gzipped-compressed files in order re-compress itself. means text that's compressed gzip have same performance other compressed format (e.g. images), say, there won't savings.

how can list of actions of controller? search cannot find example/answer. see example recommended using reflection don't know how. here trying do: public list<string> actionnames(string controllername){ } you haven't told why need 1 possibility use reflection: public list<string> actionnames(string controllername) { var types = in appdomain.currentdomain.getassemblies() t in a.gettypes() typeof(icontroller).isassignablefrom(t) && string.equals(controllername + "controller", t.name, stringcomparison.ordinalignorecase) select t; var controllertype = types.firstordefault(); if (controllertype == null) { return enumerable.empty<string>().tolist(); } return new reflectedcontrollerdescriptor(controllertype) .getcanonicalactions().select(x => x.actionname) .tolist(); } obviously know reflection not fast if intend call metho...

i'm wondering if anyhow possible partially specialize templated method behaviour in case 1 of template parameter it's of type. template<class t> void foo(t& parameter) { /* generic - types - stuff */ if(t int) // pseudo-code, typeinfo? boost? { /* specific int processing might not compile other types */ } /* again common stuff */ } any suggestion welcome. thanks if want specialize part of function have factor out part of function specialized implementations: template<class t> void bar(t &t) {} void bar(int &i) { /* specific int processing might not compile other types */ } template<class t> void foo(t &t) { /* generic - types - stuff */ bar(t); /* again common stuff */ }

is there way multiple files s3 (or cdn) in 1 request? for example, have 4 files on s3: example.com/cdn/one.js example.com/cdn/two.js example.com/cdn/three.js example.com/cdn/four.js i able request combination of them @ time. have include them separately: <script src="example.com/cdn/one.js" /> <script src="example.com/cdn/two.js" /> but include them 1 request: example.com/cdn/code.js?one&two i've considered combining needed combinations single files, there way many combinations realistic. i've considered combining of them 1 file, ridiculously large. first of all: question more js thing related s3 / cdns in general. , answer question: you can't "combine" them in 1 http request. if don't want concatenate , minify them should take @ requirejs , handle loading of scripts – it's async , won't block browser rendering. this great article async loading: css-tricks.com - thinking async giv...
