ok, i've created div dynamically in jquery display blogposts. <div class="blog-items"> <div class="blog-item"></div> </div> the jquery below adds class of nomargin remove margin on last block. how can reset loop starts again on new row. nomargin class applied remaining blocks. here's jquery excerpt var blogitemlength = $('.blog-item').length; if(blogitemlength > 2) { $('.blog-item:gt(1)').removeclass("blog-item").addclass("blog-item_nomargin"); } hope makes sense, in advance. i'd suggest, little understand of problem: $('.blog-item').filter(function(i){ return (i + 1)%3 === 0; }).removeclass('blog-item').addclass('blog-item_nomargin'); this takes .blog-item elements, filters them keep third, sixth, ninth... elements, removes blog-item class-name , adds blog-item_nomargin class-name. references: addclass() . filter() .

there changes made file in commit a, undid changes mistake , went on further make changes in commits b , c. i want changes in commit in file, changes in b , c should not lost either. let's branch @ c. i don't want $ git checkout --patch because want file contain changes made in b , c , doing checkout of file commit rewrite file in both index , working tree. i can't cherry-pick because commit merge commit(there 2 contributors repository , deleted changes mentor made mistake in subsequent commits after merged them) , might end mess if specified either parent. apart manually copying changes want in file, there other way accomplish this? you can create patch , attempt apply patch . if experience issues conflicts such error: patch failed: <file_name>:1 error: <file_name>: patch not apply the merge require manual intervention. here's example: $ git format-patch -n <sha_from_commit_you_want_to_merge> > patch_file.patch

this type of question is(with lot of variations) kinda answered but.. need blocking connect(i'm using ssl)on socket, can set time-out , maximum number of retries , necessary never lasting more t seconds. i hope there thing can set in os(linux: ubuntu/centos) or way in code(c) w/o going ugly, artificial way select wait, timeout events added epoll close socket. thank you. the simplest way use alarm system call before , after connect call , handle alarm signal, not best , useful way. better , recommended way use non-blocking socket , use poll or select system calls handle different stages of making connection. if don't want use non-blocking io way use alarm. for tutorial using non-blocking sockets refer : http://developerweb.net/viewtopic.php?id=3196 for more information happens during connect call refer to: http://www.madore.org/~david/computers/connect-intr.html

so basically, making robot object in javascript using three.js , passing in three.js scene variable object using draw robot parts through array- reason, though, scene object not pass function (it won't draw)- missing javascript functions? function robot(sc){ this.sc=sc; var robtexture = new three.meshlambertmaterial({ map: three.imageutils.loadtexture('tex/dmetal.png') }); this.parts = []; var current; //make body current=new three.mesh(new three.cubegeometry(10,15,10), robtexture); this.parts.push(current); alert("hit"); //make legs } robot.prototype.draw = function() { (x in this.parts){ this.sc.add(x); alert("hit"); } } maybe works more intended: robot.prototype.draw = function() { (x in this.parts){ this.sc.add(this.parts[x]); // < - spot difference :) alert("hit"); } }

so have application have view controller (which want appear first when app starts) , tab bar controller. have other navigation bar controllers in tab bar controller. want place view controller on top of tab bar controller. making tab bar controller parent of view controller better though. but take note, not want tab bar item represent view controller , want tab bar appear along view controller. not , not want use storyboards as possible. how can achieve this? i guess simplest solution use screenshot of tabbar , put in homeviewcontroller button. in case use homeviewcontroller rootviewcontroller , in button action set tabbarcontroller rootviewcontroller . root = home + button --> root = tabbar perhaps need 4 buttons, if want correct tab selected.
