i'm new java. have been reading getter/setter ( why use getter/setter , getter/setter poor design ). while read on oracle understanding jit . i've 2 questions follows : my question that, if jit replaces getters/setters actual value while compiling code, how purpose of getter/setter being fulfilled? how achieve encapsulation ? if jit replaces getters/setters actual value while compiling code how purpose of getter/setter fulfilled in java particular ? because it's optimization. getters , setters still work expected - , if later change implementation use different fields or other mechanism, jit compiler have change how transforms code well. for part, reasoning program design shouldn't care jit compiler @ - that's implementation detail how program happens executed. may want care achieve better performance, doesn't change whether or not program design still holds up. just because jit may compile code uses getter field directly doesn...

i got ask if there option in c#, lets got suche code : class { public a(int b); } class b : { public b(int b) : base(b); } class c : b { public c(int b) : base(b) } and if want change in class "int b" "car b" need change in every single class, possible refactor somehow automate? if possible, can use c# generics : class a<t> { public a(t b) {} } class b<t> : a<t> { public b(t b) : base(b) {} } class c<t> : b<t> { public c(t b) : base(b) { } } you can use following syntax int (and use same principle car) : var intvar = new c<int>(10); otherwise, there no tool change types @ once. if change parameter type car, resharper propose refactor constructor of derived class.

i need pattern/strategie solve problem. know book or read up? my problem (all theory): have kind of game , there have 2 npcs. workers, have repair stuff. need different materials depending on error. when error comes in calculate npc fastest. calculate each npc every move npc have take (walking, waiting,...). workers occupied time task, have consider in calculation. now thoght use same code (with little modification) let npc walk after decided 1 fit best task, in eyes that's huge redundancy , avoid that. have stop tasks midway , let npc go work somewhere else. don't think easy handle way. so second thought create working chain. in time calculation decide npc have to/where walk. could, @ point, add writes action list. loop execute actions , easy stop @ point. (of course have 2 lists after each calculation, 1 each npc. fastest used.) if there pattern or alike came with, appreciate if point me source. or there better way solve that? -regards edit: the time calcu...

how may situation represented onto class diagram more elegant (and professional) way (using inheritances ?) ? an actor [class] can physical person [class] or company [class], not both. actor can inner actor [class] or external actor [class], not both. inner actor can physical person or company, not both. external actor can physical person or company, not both. of course, here, each said class has specific attributes, methods , relations other classes onto diagram. if don't mind multi-inheritance consider that: (the inner actor displayed tow times simplify diagram, same class.)

i cannot figure out how arrange 2 side-by-side plots explained in knitr graphics manual page 2 ( http://yihui.name/knitr/demo/graphics/ ). use following mwe , output below. them aligned shown in manual 2 cars plots (also on page 2 of manual). pdf generated in rstudio (knit pdf). --- title: "untitled" output: pdf_document --- ## r markdown ```{r,echo=false,out.width='.49\\linewidth', fig.width=3, fig.height=3} barplot(1:4) barplot(4:7) ``` to center 2 plots can add fig.align='center' to chunk options. if produces 1 plot above other add fig.show='hold' . result should 2 centered graphs. so final chunk option should like: {r,echo=false, out.width='.49\\linewidth', fig.width=3, fig.height=3,fig.show='hold',fig.align='center'}

i use fullcalendar scheduler add-on ( http://fullcalendar.io/docs/scheduler/ ) when use code below, background event not coloured silver in safari / firefox /ie (no color @ all...). shows silver color in chrome. $('#calendar').fullcalendar({ events: [ { start: '2016-04-01 06:00', end: '2014-04-01 10:00', rendering: 'background', color: 'silver', resourceid: 1 } ] }); how can fix issue? thanks in advance! kind regards, kim you can set classname attribute of events events: [ { start: '2016-04-01 06:00', end: '2014-04-01 10:00', rendering: 'background', classname: event_silver, resourceid: 1 } and in css: .event_silver { background-color: silver; } kind regards, romain

for simple adts, can obtain adt of sets of adt data set = full set (*repeated n times) | empty set(*repeated n times) , n number of non terminal constructors of adt. more solid example, take nat : data nat = succ nat | 0 we can obtain type sets of nats follows: data natset = full natset | empty natset so, example, empty :: natset empty = empty empty insert :: nat -> natset -> natset insert 0 (empty natverse) = full natverse insert 0 (full natverse) = full natverse insert (succ nat) (empty natverse) = empty (insert nat natverse) insert (succ nat) (full natverse) = full (insert nat natverse) member :: nat -> natset -> bool member 0 (full natverse) = true member 0 (empty natverse) = false member (succ nat) (empty natverse) = member nat natverse member (succ nat) (full natverse) = member nat natverse main = let set = foldr insert empty [zero, succ (succ zero), succ (succ (succ (succ (succ zero))))] print $ member 0 set p...

while working in spss did glm univariate analysis obtain parameter estimates table. analysis sets last value of series zero. want set value 0 (as redundant value), in case cow_nr=0. how do this? my parameter estimates thank in advance. use constrast specification (the /contrasts subcommand or subdialog box) set reference categories appropriate contrast.

playing through wargames , curious if possible (they want solve in different way, still). there's .c file function has code looks this: char buffer[20]; scanf("%s", buffer); char* hash = crypt(buffer, "$6$") char* password = "$6$123456abcdef" #long string if (strcmp(password, hash) == 0) supersecretfunction(); is there way brute force considering salt , hashed password known already? unlike original des-based crypt() algorithm used in older unix variants, brute forced relatively modest modern resources, newer unices including gnu/linux flavours use extended encrypted password specification. can recognize if encrypted password (or salt) start "$id$" "id" algorithm identifier, see table below. "$6$" indicates sha-512 used encryption (well, hashing actually). after second '$' comes salt, '$' , sha-512 of password. the sha-512 algorithm used decribed in detail here: ftp://ftp.arlut.utex...

i using boost's date object want year object string or int i didn't find simple way thank you! ron #include <boost/date_time/local_time/local_time.hpp> #include <boost/lexical_cast.hpp> #include <string> std::string x = boost::lexical_cast<std::string> (second_clock::local_time().date().year()); should do.

suppose have git history this: a-b-c-d-e-f-g b added 60k files. f removed same files. any operation traverses git history, such git log , takes stupid amount of time if has cross f (or b). is there way remove b , f history, given cancel each other out? more point: there easy way this, , ensure other developers using repo date? (bear in mind said developers have feature branches sitting on machines.) suspect solutions going end resulting in a-c'-d'-e'-g' ... my gut says best i'm going create branch a, cherry-pick c through e, create new branch g, , merge onto first branch. or something. just git rebase -i a , remove lines b , f. said (or meant), rewrite published history, fellow developers need rebase branches based off manipulated branch described in man page of git rebase under section "how recover upstream rebase".

i have tscrollbox on form. placed onto scrollbox tlayout wider , taller device viewport horiz , vert scrollbars show , user can manually move layout. i have gesture setup user can longpress scrollbox , layout origin (0,0). procedure tfrmmain.scrollbox1gesture(sender: tobject; const eventinfo: tgestureeventinfo; var handled: boolean); begin if eventinfo.gestureid = system.uitypes.igilongtap begin scrollbox1.viewportposition := pointf(0, 0); scrollbox1.realigncontent; end; now works great, happens rather quickly. thought perhaps use: tanimator.animatefloat(scrollbox1, 'scrollbox1.viewportposition.x', 0, 0.3); to make movement current position 0 bit more gentle, of course, that's never going work because can't assign value pointf.x or pointf.y directly (and therefore neither can animator). so how can done? thanks as built-in pointanimation missing, here self written one. type tpointanimation = class(tcustompropertyanimatio...
