what's difference between inner workings of java's jvm , .net's clr? perhaps starting point be, same thing in respective environments (java > jvm > machine code) (c# > clr > il). update: several people have alluded points trying cover: garbage collection boxing/unboxing jit debugging generics/templates please feel free suggest other topics differentiate two. @george mauer - sounds interesting: already posted once here series of interviews c# chief language designer anders hejlsberg. already posted once here series of interviews c# chief language designer anders hejlsberg. though talking differences between c# , java dive differences between virtual machines well.

sizeof() doesn't work when applied bitfields: # cat p.c #include<stdio.h> int main( int argc, char **argv ) { struct { unsigned int bitfield : 3; } s; fprintf( stdout, "size=%d\n", sizeof(s.bitfield) ); } # gcc p.c -o p p.c: in function ‘main’: p.c:5: error: ‘sizeof’ applied bit-field ...obviously, since can't return floating point partial size or something. however, brought interesting question. is there equivalent, in c, tell number of bits in variable/type? ideally, work regular types well, char , int , in addition bitfields. update: if there's no language equivalent of sizeof() bitfields, efficient way of calculating - @ runtime! imagine have loops depend on this, , don't want them break if change size of bitfield - , no fair cheating , making bitfield size , loop length macro. ;-) you cannot determine size of bit-fields in c. can, however, find out size in bits of other types using value of char_bit...

i've been working through practical common lisp , exercise decided write macro determine if number multiple of number: (defmacro multp (value factor) `(= (rem ,value ,factor) 0)) so : (multp 40 10) evaluates true whilst (multp 40 13) not the question macro leak in way? "good" lisp? there existing function/macro have used? siebel gives extensive rundown (for simple cases anyway) of possible sources of leaks, , there aren't of here. both value , factor evaluated once , in order, , rem doesn't have side effects. this not lisp though, because there's no reason use macro in case. function (defun multp (value factor) (zerop (rem value factor))) is identical practical purposes. (note use of zerop . think makes things clearer in case, in cases need highlight, value you're testing might still meaningful if it's other zero, (= ... 0) might better)

what guidelines follow improve general quality of code? many people have rules how write c++ code (supposedly) make harder make mistakes. i've seen people insist every if statement followed brace block ( {...} ). i'm interested in guidelines other people follow, , reasons behind them. i'm interested in guidelines think rubbish, commonly held. can suggest few? to ball rolling, i'll mention few start with: always use braces after every if / else statement (mentioned above). rationale behind it's not easy tell if single statement 1 statement, or preprocessor macro expands more 1 statement, code break: // top of file: #define statement dosomething(); dosomethingelse // in implementation: if (somecondition) dosomething(); but if use braces work expected. use preprocessor macros conditional compilation only. preprocessor macros can cause sorts of hell, since don't allow c++ scoping rules. i've run aground many times...

while convenient use inline functions @ situations, are there drawbacks inline functions? conclusion : apparently, there nothing wrong using inline functions. but worth noting following points! overuse of inlining can make programs slower. depending on function's size, inlining can cause code size increase or decrease. inlining small accessor function decrease code size while inlining large function can dramatically increase code size. on modern processors smaller code runs faster due better use of instruction cache. - google guidelines the speed benefits of inline functions tend diminish function grows in size. @ point overhead of function call becomes small compared execution of function body, , benefit lost - source there few situations inline function may not work: for function returning values; if return statement exists. for function not returning values; if loop, switch or goto statement exists. if function recursive. -source the __inline keyword cau...

sometimes have work on code moves computer clock forward. in case .cpp or .h files latest modification date set future time. later on, when clock fixed, , compile sources, system rebuilds of project because of latest modification dates in future. each subsequent recompile has same problem. solution know are: a) find file has future time , re-save it. method not ideal because project big , takes time windows advanced search find files changed. b) delete whole project , re-check out svn. does know how can around problem? is there perhaps setting in visual studio allow me tell compiler use archive bit instead of last modification date detect source file changes? or perhaps there recursive modification date reset tool can used in situation? if problem, i'd ways avoid mucking system time. isolating code under unit tests, or virtual machine, or something. however, because love powershell : get-childitem -r . | ? { $_.lastwritetime -gt ([datetime]::no...

i have counter in hardware can observe timing considerations. counts miliseconds , stored in 16 bit unsigned value. how safely check if timer value has passed time , safely handle inevitable rollover: //this bit contrived, illustrates i'm trying const uint16_t print_interval = 5000; // milliseconds static uint16_t last_print_time; if(ms_timer() - last_print_time > print_interval) { printf("fault!\n"); last_print_time = ms_timer(); } this code fail when ms_timer overflows 0. you don't need here. original code listed in question work fine, assuming ms_timer() returns value of type uint16_t. (also assuming timer doesn't overflow twice between checks...) to convince case, try following test: uint16_t t1 = 0xfff0; uint16_t t2 = 0x0010; uint16_t dt = t2 - t1; dt equal 0x20 .

hopefully haven't misunderstood meaning of "duck typing", i've read, means should write code based on how object responds methods rather type/class is. here's code: def convert_hash(hash) if hash.keys.all? { |k| k.is_a?(integer) } return hash elsif hash.keys.all? { |k| k.is_a?(property) } new_hash = {} hash.each_pair {|k,v| new_hash[k.id] = v} return new_hash else raise "custom attribute keys should id's or property objects" end end what want make sure end hash keys integer representing id of activerecord object. don't particularly enjoy having iterate through hash keys twice all? determine if need grab id's out. of course, i'll accept other suggestions improve code :) how write method should depend on whether expect exception thrown during course of normal program execution. if want readable exception message because end-user might see it, throwing 1 manually makes sense. otherwise, i...

all. know if there way read out values in compiled resource (*.res) file. familiar reading resources executable, , i'm wondering if there similar way read out resources resource file. in advance! the windows functionality dealing res files deals them exclusively embedded resources. typically application ship localized resources contained in resource dlls. loadlibraryex takes flags load_library_as_datafile used prevent dlls dllmain being called. the you're going microsoft wrt loading res files directly this msdn page if manipulation of resources want beginupdateresource updateresource, endupdateresource api can use inject (or modify) version resource in existing dll.

i'm having small problem in java. have interface called modifiable. objects implementing interface modifiable. i have modifycommand class (with command pattern) receive 2 modifiable objects (to swap them in list further on - that's not question, designed solution already). the modifycommand class starts making clones of modifiable objects. logically, made modifiable interface extends cloneable. interface defines clone() method implementing classes must redefine. then, in modifycommand, can : firstmodifiableobject.clone(). logic classes implementing modifiable have redefine clone method object, cloneable (that's want do). the thing is, when define classes implements modifiable , want override clone(), won't let me, stating clone() method object class hides 1 modifiable. what should do? i'm under impression "i'm doing wrong"... thanks, guillaume. edit : think forget clone() thing. either a) assume object passed modifiable object (impl...

how dig javascript, find myself asking much. example have window.onresize event handler , if say: window.onresize = resize; function resize() { console.log("resize event detected!"); } wouldn't kill other functions connected same event , log message in console? if think there should notifier tells me window resize event - or workaround maybe - without overriding other functions bound same event. or totally confused usage? you can save old onresize function , call either before or after custom resize function. example should work this: var oldresize = window.onresize; function resize() { console.log("resize event detected!"); if (typeof oldresize === 'function') { oldresize(); } } window.onresize = resize; this method can have issues if there several onresize functions. save old onresize function part of closure , call old 1 after function. function addresizeevent(func) { var oldresize = window.onres...

my app's root view controller supports orientation user can navigate view controller supports landscape orientation. the basic problem regardless of device's actual physical orientation, when user pops root view controller, navigation bar has height appropriate landscape mode. figure out how navigation bar appear height of 44 (portrait height) instead of 32 (landscape height). although navigation bar not set proper height, root view controller's uitableview offset correctly (44 pixels top of screen). inside second view controller's -viewwillappear: perform standard rotational transform: if (deviceorientation == uideviceorientationportrait) { uiscreen *screen = [uiscreen mainscreen]; cgfloat screenwidth = screen.bounds.size.width; cgfloat screenheight = screen.bounds.size.height; uiview *navview = [[self navigationcontroller] view]; navview.bounds = cgrectmake(0, 0, screenheight, screenwidth); navview.transform = cgaffinetransformidentity...

i have class 2 related functions (methods): public class class1 { public void subscribetolistofevents() { // .... } public void unsubscribefromlistofevents() { // .... } } what's best practice use related functions in 1 class ? do know of implementations of related functions 1 function ? ? in situations ? if so, can hyou give me example? any available options of code above appreciated. if functions belong class, logically, fine way. a class should cohesive , methods operation should have mirror operation defined (subscribe/unsubscribe, add/remove etc...). you have named them well, descriptive of - how name merged one? better leave them separate, way self documenting , not confuse users of class.

i need delete same line in large number of text files. have been trying use sed, cannot delete newline character @ end. following deletes line, not newline: sed -i -e 's/version:1//' *.txt i have tried using following delete newline also, not work: sed -i -e 's/version:1\n//' *.txt is there anyway specify newline in sed substitute command or there other command line tool can use achieve goal? thank you you can use sed command: sed -i -e '/version:1/d' for this. the following transcript gives example: pax> echo 'hello > goodbye > hello again' | sed '/oo/d' hello hello again you should check whether want match whole lines with, example: sed -i -e '/^version:1$/d' since, stands, delete lines following: version:10 conversion:1

when considering using performance counters companies' .net based site, wondering how big overhead of using them. do want have site continuously update it's counters or better off when measure? the performance impact negligible in updating. microsoft's intent write performance counters. it's monitoring of (or capturing of) performance counters cause degradation of performance. so, when use perfmon capture data. in effect, performance counter objects have effect of "doing when measure."
