if in master , stuff want safe git ignored, then: git checkout <oldbranch or commit> but old branch doesn't have ignored files arrgh! untracked files added etc , vulnerable reset --hard etc. is there more elegant fix here other than: git checkout master .gitignore #maybe write hook every checkout of <oldbranch or commit>? or manage copying .gitignore .git/info/exclude ? adding rules in .git/info/exclude 1 way, remains local workaround: won't pushed .gitignore file would. the best option remains create .gitignore in checked out branch: git checkout abranchwithoutgitignore git checkout master -- .gitignore git add .gitignore git commit -m "add .gitignore master" then cherry-pick commit other branches.

c# - How long does variable assignment take? -

-
i've come across code made liberal use of variables var self = this; code nicer. while don't think assignments these going significant @ in piece of code, i've wondered how long assignment above take. with said: how long take, assuming isn't optimized away? how times compare between different languages- e.g. c#, java, , c++? common value types (including pointers)? 32 / 64-bit architectures? edit: erased part "noticeable difference". meant part side-question, many people have seen , started downvoting me premature optimization (in spite of me highlighting bottleneck part in bold). the code: var self = this; isn't creating new instance of object 'this', referencing pointer object 'this'. @ machine level there 1 pointer since c# compiler optimizes these types of reference out. "how long takes" zero. so, why 'this'? because makes code easier read.

ios - How to allow user to crop a fixed frame of an image iPhone -

i trying find way allow user select part of image he/she wants use. crop size fixed, user can't adjust how big or small want photo. in mind, screen display photo rectangle on it, user move around his/her touch. press "ok" , image cropped wherever rectangle was. right code is: (uiimage *)imagebycropping:(uiimage *)imagetocrop torect:(cgrect)rect { cgimageref imageref = cgimagecreatewithimageinrect([imagetocrop cgimage], rect); uiimage *cropped = [uiimage imagewithcgimage:imageref]; cgimagerelease(imageref); return cropped; } this code automatically crops image center without giving user chance crop him/herself. i'm thinking along lines of this: in above image, user moves picture around in background until part within box want keep, while cropping rest. can zoom in , out on photo pinching.

when send block of r code interpreter in rstudio (or tinn-r or other environment) if there's error on line 1, lines 2, 3, 4 ... still execute. why default behavior? seems contrary how programming languages work , dangerous in sense if line 1 produces error alter subsequent lines of code do. it's particularly bad in long scripts have lot of printed output because can miss error message amidst regular output. there reason, either logical or historical, why r works way? , possible change behavior , ensure interpreter stop upon encountering error? consider r code error: print("starting") b+sdlkfjsflkj print("hello world") if select code , copy interpreter, describe continue past error: > print("starting") [1] "starting" > b+sdlkfjsflkj error: object 'b' not found > print("hello world") [1] "hello world" a simple solution causes stop @ error storing in script , running source : source

angularjs - Using ui-router and ocLazyLoad to load a controller and set the partial to it -

i'm complete angular noob , trying fancy stuff quickly, forgive me if dumb question. i've created website uses routing, , i'm using ui-router routing instead of standard angular router. theory still same - have index.html page in root of website "master" or "host" page, , loginview.htm, partial, exists in separate directory. the maincontroller project loaded in index.html page. referencing controller not cause error or problem. what i'd do, in order keep code manageable , small, have custom controller partial page lazy load when load partial, , associate partial page newly loaded controller. makes sense, right? don't want load controllers default, because that's waste of time , space. so structure looks (if matters anyone): root --app/ ----admin/ ------login/ --------loginview.html --------logincontroller.js --maincontroller.js index.html this logincontroller code. testing purposes, have made maincontroller code match exactly.

bit manipulation - set most significant bit in C -

-
i trying set significant bit in long long unsigned, x. using line of code: x |= 1<<((sizeof(x)*8)-1); i thought should work, because sizeof gives size in bytes, multiplied 8 , subtract 1 set final bit. whenever that, compiler has warning: "warning: left shift count >= width of type" i don't understand why error occurring. the 1 shifting constant of type int , means shifting int value sizeof(unsigned long long) * 8) - 1 bits. shift can more width of int , apparently happened in case. if want obtain bit-mask mask of unsigned long long type, should start initial bit-mask of unsigned long long type, not of int type. 1ull << (sizeof(x) * char_bit) - 1 an arguably better way build same mask be ~(-1ull >> 1) or ~(~0ull >> 1)
