i have input fields required attr <input id="name" required="" placeholder="write name"> additionally have button makes post , other link makes postback well. but in case input field has't data chrome block post-back action, , show chrome pupup box information need fill data on form. in same time ie allows it. how resole ? of course can remove attribute javascript before post-back action, not sure right way. i think shouldn't count on html5 required attribute since (in case of ie) ie 10+ supports (see "form validation" section here: web forms - dive html5 ). of course, same goes placeholder attribute in cases it's can live (and having working validation more critical). i think should use validation functionality provided asp.net itself, it's easy started , can make work , without javascript enabled on client. more info here: understanding asp.net validation techniques .

i'm sorry if question bit vague i'll try explain it. i got code: public string tostring() { string s = "text.\n"; (klus k : alleklussen) { s += k.tostring() + ".\n"; } return s; } but want make different loops different conditions. example, "klus" has couple of variables like: status, date etc. i'm not experienced java yet, possible this: for (klus k : alleklussen; status = "completed") {..} i know wrong i'd show "klus" objects status "completed" , "klus" objects statis "not completed". thanks , if unclear or used wrong word something, please tell me. edit: it should make this: if (k.getstatus().equals("completed"){ string s = "completed ones \n" s += k.tostring() + ".\n"; //get completed ones } if (k.getstatus().equals("uncompleted"){ string s = "uncompleted ones \n" s ...

i'm testing app in iphone5. i duplicate image, named image1.png , image1@2x.png, , tried in iphone5, in part of code: uiimage *myimage = [uiimage imagenamed:@"image1.png"] ; cgfloat imagewidth = myimage.size.width; cgfloat imageheight = myimage.size.height; nslog(@"image %f %f", imagewidth,imageheight); cgrect screenbound = [[uiscreen mainscreen] bounds]; cgsize screensize = screenbound.size; cgfloat screenwidth = screensize.width; cgfloat screenheight = screensize.height; nslog(@"screen %f %f", screenwidth, screenheight); and when running in iphone, in console see: 2013-04-05 13:13:48.386 vallabici[2413:907] image 320.000000 57.000000 2013-04-05 13:13:48.389 vallabici[2413:907] screen 320.000000 568.000000 as using normal screen instead of retina. how can be? the size of image should not change on retina device, scale. take scale of image add following log: nslog(@"scale %f", myimage.scale);

i've setup git environment (mo github) have remote: 1 branch local: master branch , featurex branch work on it/ now, on remote teammate pushed on remote feature on remote want on feature branch. which right steps that? the concept of remote , local branches can little bit confusing in beginning. if want keep local branch "master" in sync remote branch git pull suggested in answer here way of doing so. there way of keeping remote branch while still working on featurex branch without leaving branch: merge friends changes directly remote branch. git fetch git merge origin/master

for elki need (and have) more flexible sorting implementations provided standard java jdk , collections api. (sorting not ultimate goal. use partial sorting bulk loading index structures such k-d-tree , r*-tree, , want make rather generic implementation of these available, more generic in elki - either way, optimizing sort means optimizing index construction time). however, sorting algorithms scale differently depending on data size. tiny arrays, known fact insertion sort can perform (and in fact, quicksort implementations fall insertion sort below threshold); not theory cpu pipelining , code size effects not considered sorting theory. so i'm benchmarking number of sorting implementations find best combination particular needs; want more flexible implementations on par jdk default implementations (which fine tuned, maybe different jdk version). in long run, need these things easy reproduce , re-run. @ point, we'll see jdk8. , on dalvik vm, results may different on ja...

web application. c#, sql 2k8 in list, there lot of things going on, before actual dynamic sql gets executed, , returns desired records. recently added code whole app (deadlock issues) transaction commit, , rollback , retry x times, whole 9 yards. that big plus, needed that. but in order debug possible issues list, saving dynamic sql string in log table (which doesn't store old records last couple of weeks) problem is: right there no log, if list crashes. because of rollback stuff ... my best idea far call list twice: "check" - mode, create dynamic sql, save in log tbl, not exec "list" - mode either: 2a. recalculate dynamic sql or 2b. reuse dynamic sql created "check - mode either 2a or 2b, should not have huge performance issue, because expensive part of list stored procedure actual execution of dynamic sql. "check" - mode basic string concatenation. the deadlock retry part second db call, good! still. not happie...
