i'm learning native ios development first time, , came across struct nsrange. come java background don't see reasoning using range struct when can use substring methods part of nsstring class. advantage of using range structs on using non-range nsstring substring methods. thanks! edit: looks considering substring methods: substringfromindex: , substringtoindex: . considering inflexibility of these methods (ie. not being able choose both start , end point) makes range struct instances more necessary. though guess nest 2 methods achieve same result. edit 2: examples. non-range substring method examples: nsstring *str = @"this string."; nsstring *substr = [str substringtoindex:7]; nsstring *substr2 = [str substringfromindex:7]; ranges substring method example: nsstring *substr3 = [str substringwithrange:nsmakerange(5, 5)]; because range based methods offer lot more flexibility, , usable of nsstring search methods (which use ranges heavily

i've implemented google play services demo code found @ url: https://github.com/kpbird/google-play-service/blob/master/src/com/kpbird/googleplayservice/mainactivity.java and works. if function getaccountnames() called within oncreate, application momentarialy flashes before loading set content view. it's there 2 activity views being initiatied. @override protected void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.activity_main); txtaccount = (textview) findviewbyid(r.id.txtaccount); txttoken = (textview) findviewbyid(r.id.txttoken); getaccountnames(); } why placing getaccountnames() in oncreate create visual effect when application launches.

jekyll supplies site.categories variable accessible liquid templates. in site have 2 categories 1 post each. looking @ jekyll bootstrap categories.html know: {% category in site.categories %} {{ category[0] }} i know renders category's name. if do: {% item in category %} {{ item }} it seems category has 2 items: name , post. makes no sense me. category[0] name , array of posts starts @ index 1? why make sense? wonder if comes ruby somehow, don't know ruby. (since jekyll written in ruby i'm adding tag, since suspect of syntax derivative.) how determine structure of site.categories ? don't know how debug , don't understand liquid syntax enough know why behavior makes sense. site.categories multi-dimensional array of categories. each category consists of it's name first element, , list of posts contained in category. posts consist of name, content, permalink , more (the same info in site.posts entries).

i saw code , couldn't understand doing compiled succesfully.i searched ~~ operator no luck. unless ($1 ~~ @tables) { push @tables, $1; } reference: http://perldoc.perl.org/perlop.html#smartmatch-operator first available in perl 5.10.1 (the 5.10.0 version behaved differently), binary ~~ "smartmatch" between arguments. the ~~ operator compares operands "polymorphically", determining how compare them according actual types (numeric, string, array, hash, etc.) equality operators shares same precedence, ~~ returns 1 true , "" false. best read aloud "in", "inside of", or "is contained in", because left operand looked inside right operand. makes order of operands smartmatch operand opposite of regular match operator. in other words, "smaller" thing placed in left operand , larger 1 in right.

i've written small command compile every c file in every directory , have: find $1 -type f -name '*.c' -exec sh -c 'gcc {} -o $(dirname {})/$(basename {} .c)' \; and compiles everything, display status of each file being compiled, , display when each 1 finished, i'm out if ideas. if love that! this academic issue, using {} multiple times in argument find not portable. similarly, expecting {} expand filename when not string in argument not portable. (that is, entire argument must {} ). also, using gcc explicitly rather make wrong approach. said, can echo each path compiles: find $1 -type f -name '*.c' -exec sh -c 'gcc $0 -o $(dirname $0)/$(basename $0.c) && echo $0' {} \; also, if can simplify bash: find $1 -type f -name '*.c' -exec bash -c 'gcc $0 -o ${0%.c}.o && echo $0' {} \;

i want gradually migrate multi-module maven build multi-module gradle build. i'm using m2e maven tooling in eclipse , 1 feature if projecta depends on projectb , both projects in eclipse workspace, m2e smart enough use local .class files projectb instead of using .jar file maven repository. let's call feature "local resolution". so, can eclipse gradle tooling , m2e play nicely together? if gradle project depends on maven project, can maven project locally resolved if maven project depends on gradle project, can gradle project locally resolved if gradle project depends on gradle project, can dependent gradle project locally resolved? resolving local gradle projects blocked until gradle-2750 resolved. current state this: local resolution works gradle project depending on maven project (fixed in version 3.1.0.m1) local resolution fails maven project depending on gradle project local resolution fails gradle project depending on gradle projec

i have following code (from related) works finding reference opened windows , closing them. var playerurl = 'http://my.player...'; var popupplayer= window.open('', 'popupplayer', 'width=150,height=100') ; if(popupplayer.location == 'about:blank' ){ popupplayer.location = playerurl ; } popupplayer.focus(); this works across tabs in firefox, in chrome seems if each separate tab unaware of happening in other tabs. i'd suspect due each tab being different process there anyway bypass this? so basically, if open window page in tab a, can reference window page b in tab b, , close in chrome? related to: find window opened window.open https://stackoverflow.com/a/16525481/1688441 edit: i found may useful messaging other tabs close action, though haven't tested in chrome: sending message open windows/tabs using javascript i've used pubsub functionality of jstorage before this. it's dependent on jquery, may

i'm uploading data excel file using xlrd , turning data models (with integerfield values) in django. excel file has bunch of missing data. unfortunately, these missing data converted value of 0 in models, instead of null. means when person model doesn't have age, age gets recorded 0, instead of null. what's best way change this? i've tried doing this: age = models.integerfield(blank=true, null=true) but blank fields still set 0 default. instead of using age = models.integerfield(blank=true, null=true) use age = models.integerfield() when donot specify blank=true, null=true it store null in column

i have strongly-typed razor 2 editor template. when view model meets conditions, want view delegate alternative template of same type. use templatename argument editorfor helper select alternative template: @model mytype @if (model.isspecialcase) { @html.editorfor(m => m, "specialcasetemplate") } else { @* default markup *@ } problem is, razor not call alternative template; passes on editorfor method. if change type of second template, shows correctly. can work around using partial view, rather not, have scheme going editor templates want stick to. anyone know how can work? edit looks has behaviour described here: asp.net mvc - using editorfor same model type twice . in short, mvc not support using editorfor method on same object twice. the best way this, returning different view controller: public actionresult someaction(){ var model = ...; if (model.isspecialcase){ return view("specialcasetemplate"); } el
