the scenario i have table on web page dynamically generated using jsp. number of columns/headers variable (could 6 or 40+). i'm using jquery tablesorter sort table. table should sort on header elements 5 , 6 moment. the question using tablesorter allows set header elements false , disabling them sort options. since number of headers variable need way of inverting options can set sorter option true , rest disabled default. either that, or need way total number of header elements , run through loop set them false. the syntax little tricky me i'm not sure how loop through following: $(document).ready(function() { $("table").tablesorter({ headers: { 0: { sorter: false }, 1: { sorter: false } . . . } }); }); so 2 want sort on in example "primary di

is possible execute child process in node.js custom stdin under linux? the documention refers stdinstream internal use only: there several internal options. in particular stdinstream, stdoutstream, stderrstream. internal use only. undocumented apis in node, should not used. why it's internal use only? tried give custom readablestream it, yielded nasty v8 exception. no surprise after using internal api... some background: need execute git commit after node.js process has closed stdin (this cannot workaround currently). issue git gets angry @ if try commit closed stdin . update: issue originates a node.js bug , i'll keep question here since think i'm not 1 wondering this. rather using stdinstream , think should use customfds instead. same documentation: there deprecated option called customfds allows 1 specify specific file descriptors stdio of child process. api not portable platforms , therefore removed. customfds possible hook new

i've never seen hover effect before, , i'm trying understand how it's achieved. you'll notice in example, when user hovers on link, color link turns can any 1 one of 5 colors assigned within style sheet (see below) @ random. how create hover effect? can done purely css? a:hover { color:#1ace84; text-decoration: none; padding-bottom: 2px; border: 0; background-image: none; } a.green:hover { color: #1ace84; } a.purple:hover { color: #a262c0; } a.teal:hover { color: #4ac0aa; } a.violet:hover { color: #8c78ba; } a.pink:hover { color: #d529cd; } since random factor introduced, don't think there's way of doing purely css. here's simple approach problem, using jquery. you can see working example here: http://jsfiddle.net/gngjz/1/ $(document).ready(function() { $("a").hover(function(e) { var randomclass = getrandomclass(); $(e.target).attr("class", randomclass); }); }); function ge

this general question comes answer issue interests me general knowledge , not answer specific problem. i wondering available ways implement physical engine objects interact each other , outside forces. example can @ angry birds, or games tim . there objects "fly" through air, collide , interact each other, , affected potential of environment gravity, winds , other "forces". the model have thought each object has object (as object of class) , thread relate it. each time slot thread "advances" object in space small dt. in case have "environment" object can position in space , give equivalent force applied environment potential. can't how objects interact each other? also, close in direction? there other solutions , models problems, , better? things i'm missing (i must missing things)? the implementation typically nothing describe, way expensive. instead, reduced matrix transformations. points lists of coordinates operat

i using jquery datatables generate paginated table on site. need run process grabs of data out of particular column. : $('.testlink').click(function(){ var cells = new array(); $('#mytable tr td').each(function(){ cells.push($(this).html()); }); console.log(cells); }); that example grabs need information 1 column of tds. guess adding class of tds in row sure there better way. bonus question.. but want know how work datatables? because script hides of table put in pagination function grabs cells visible. played around fngetdata not getting it. ideas? to access rows, can do: var rows = $("#mytable").datatable().fngetnodes(); in case, should work: $('.testlink').click(function(){ var cells = []; var rows = $("#mytable").datatable().fngetnodes(); for(var i=0;i<rows.length;i++) { // html of 3rd

i have form variable number of textboxes, , when click save (the submit button), want remove empty ones , save form without empty boxes. but it's half-working. when click save, empty boxes visually removed. moreover, there's validation error when boxes left empty, removeemptyboxes() there no validation error know boxes somehow removed before submit. when page refreshes, empty boxes reappear. on other hand, if divide 2 buttons , use 1 button removeemptyboxes() , click other button save, works fine , deleted boxes stay deleted. i'm sure can round in different way, it's frustrating doesn't work way want to. there way this? my form made using ajax.beginform. button looks this: <input name="xisubmit" type="submit" value="save" onclick="removeemptyboxes()" /> function removeemptyboxes() { $('div.box').each(function () { var content = $(this).find('.box-content').val(); if (content

i have website uses cakephp 1.3.10. cakephp app it's pretty big, not in amount of models or controllers (like 5 of each), in amount of plugins. use plugins places of website users can access (or can't access) depending on if have logged in or not (well there's more reasons, it's not important now, it's how works). use global auth component in app_controller.php my issue following: i've noticed website getting slow when trying access of pages of plugin (when accessing "home" page - not in plugin - good). the thing going run performance tests figure out what's going on. decided create website, 1 described, difference removed plugins exception of one. amazingly (for me), when access 1 of pages of plugin didn't delete, goes super fast, should go. so question is: number of plugins have direct impact on loading times of page inside plugins? there way "fix" this? or coincidence , else going on missed? thanks in advance advise!

i have table populated data need use run second query. using jquery datatables , functions see allow me grab content table. example grabbing integer out of fourth column , using number run query json response : var cells = []; var rows = otable.fngetnodes(); for( var i=0;i<rows.length;i++) { var grabsku = $j(rows[i]).find('td:eq(3)').text(); grabsku = grabsku.substring(0, 6) + "-0" + grabsku.substring(7, grabsku.length - 4); s7url = 'http://jsonquery.com/' + grabsku + '?req=exists,json'; $j.ajax({ url: s7url, datatype: 'jsonp' }); } then ajax request json returns either 1 or 0 can form correct info depending on returned. function s7jsonresponse(response) { var s7img = sku; s7img = '<img src="http://imageserver.com/is/image/' + s7img.substring(0, 6) + "-0" + s7img.substring(7, s7img.length -

i trying create code in java can determine date of next recurring time of week specified. hard explain i'll give example. march 1st (a thursday) , user wants know when next saturday 5:00 code should output march 3rd, 5:00 date variable , if march 4th, program should output march 10th , on... the user however, can specify time of week want. done long value offsets time of week thursday 0:00 in milliseconds. i'm having trouble wrapping head around got far: public static long findnexttimeoftheweek(long offset) { return system.currenttimemillis() - ((system.currenttimemillis() - offset) % 604800000) + 604800000; } if help, appreciated. , if more clarification needed, ask. p.s. 604800000 number of milliseconds in week. i suggest use calendar class, can manipulate , date object using calendar#gettime . see example below, want: import java.util.calendar; import java.util.locale; import java.util.scanner; public class main { public static int dayofweeki

i writing simulation program proceeds in discrete steps. simulation consists of many nodes, each of has floating-point value associated re-calculated on every step. result can positive, negative or zero. in case result 0 or less happens. far seems straightforward - can each node: if (value <= 0.0f) something_happens(); a problem has arisen, however, after recent changes made program in re-arranged order in calculations done. in perfect world values still come out same after re-arrangement, because of imprecision of floating point representation come out different. since calculations each step depend on results of previous step, these slight variations in results can accumulate larger variations simulation proceeds. here's simple example program demonstrates phenomena i'm describing: float f1 = 0.000001f, f2 = 0.000002f; f1 += 0.000004f; // part happens first here f1 += (f2 * 0.000003f); printf("%.16f\n", f1); f1 = 0.000001f, f2 = 0.000002f; f1 += (f2

for each each item available render partial view, in partial view have checkbox. purpose the user can select multiple items @ once, when hit delete items selected deleted. checkbox in partial view not within form like: <%= html.checkbox("isselected", model.isselected)%> so displays correctly, nothing. i asked question binding value model checkbox , worked fine. did: <%= html.checkbox("["+itemx+"].isselected", x.isselected) %> but have create partial view wondering how tie , values partial view? thanks. @felipe: answer not wrong, small performance improvement not call html.partial in loop. instead, call html.partial ones , pass in ienumerable model , loop through items in partial view. more info on topic: http://channel9.msdn.com/series/mvcconf/mvcconf-2-steven-smith-improving-aspnet-mvc-application-performance

is possible? what i'm doing using this code wherein after line 37 intend setup cookie of own indicating logged in , redirect browser page. think that's not secure since user can javascript , mess cookie. isn't fb js sdk must doing behind scene, setting cookie? how can securely log in user website(i maintaining db table of fb ids)? you no need set separate cookie when using fb login authentication , data(fb uid). but still bit confused u ve do. far understood, if login u want redirect user other page else show him login button is correct?? then this: 1) have custom login button instead of fbml login button(make invisible first). 2) in setup() method if " response.status " connected redirect else show login button - onclick of button call fb.login() http://developers.facebook.com/docs/reference/javascript/fb.login/ login , authentication of ur site. 3) subscribe " auth.statuschange " instead " auth.login " http://

i have script opens window online application after executing other scripts. window.open() not called on click. getting called in script , browser prevents new window appearing. how overcome this? here code.. window.open('/search/applyonline?jobid=".$jobdetails->getidjob()."', 'applyurljob', 'height=550,\ width=800,\ toolbar=no,\ directories=no,\ status=no,\ menubar=no,\ scrollbars=yes,\ resizable=yes,\ left=200,\ top=250') popup blockers block windows being opened not in response click event. therefore can: ask users turn off popup blocker (not nice). change scripts work in response link or button click. use fake windows such jquery ui dialog .

in of classes accessors declared getname1 , in others getname2 . usage perspective, looks identical. there performance benefit of 1 on other in decent compiler? there cases should use 1 of two? class myclass { public: myclass(const string& name_):_name(name_) { } string getname1() const { return _name; } const string& getname2() const { return _name; } private: string _name; }; int main() { myclass c("bala"); string s1 = c.getname1(); const string& s2 = c.getname1(); string s3 = c.getname2(); const string& s4 = c.getname2(); return 0; } returning reference potentially faster, because no copy needs made (although in many circumstances return-value optimization applies. however, increases coupling. consider happens if want change internal implementation of class store name in different way (i.e. no longer in string ). there no longer return reference, need change public interf

i need store release build of flash builder (flex) application in subversion. when try add version control via subclipse warning telling me have asked version control 1 or more resources otherwise have been ignored. know why happening, , how can around it? i've gotten around 1 time in past adding build release's directory repository using subversion client, i.e. outside of eclipse/flash builder, when rebuilt release later unable subclipse see changes between base/head revisions , new local versions of build release files. i realize i'm doing non-standard , suspect there default svn:ignore settings someplace causing happen, can't figure out these in order modify/bypass them. or maybe there's else going on? thanks in advance insight and/or issue. this eclipse-specific feature. eclipse has feature files produced compilers or generates inside eclipse can marked in eclipse "derived" resources. eclipse team providers supposed ignore these

i'm trying remove value of array, without removing methods. consider following code: var project = function () { //the array data stored before sent.. this.data = []; // ... along function send data other source ... this.data.send = function () { } //here data altered ... //send data ... this.data.send(); //remove data, don't want when sending next time ... this.data = []; // ... (obviously) results in removal of send() function ... :-( } which remove function .send() , not behavior i'm looking for. what's smoothest , proper way dodge problem? thanks! sirko's suggestion should work, issue points design flaw, in opinion. why not expose array object, methods never changes, has internal array can manipulate @ will. var data = { items: [], push: function(item) { this.items.push(item); }, send: function() { // send items this.items = []; } } data.push('abc'); data.send()

i have numpy masked matrix. , wanted interpolation in masked regions. tried rectbivariatespline didn't recognize masked regions masked , used points interpolate. tried bisplrep after creating x,y,z 1d vectors. each of length 45900. took lot of time calculate bsplines. , gave segmentation fault while running bisplev . 2d matrix of size 270x170. is there way make rectbivariatespline not include masked regions in interpolation? or there other method? bisplrep slow. thanking you, indiajoe update : when grid small scipy.interpolate.rbf 'linear' function doing reasonable job. gives error when array large. is there other function allow me interpolate , smooth matrix? i have concluded following. correct me if wrong. 1) rectbivariatespline requires perfect filled matrix , hence masked matrices cannot used. very late, but... i have problem similar yours, , getting segmentation fault bisplines, , memory error rbf (in "thin_plate" function works g

if http method not upper-case, nginx rejects request , sends 400 response along internal 400 html error page. no details shown on "error_log info" example: link, link, search, verb, etc ... upper-case versions of work, jut mixed case. from http 1.1 rfc ; the method token indicates method performed on resource identified request-uri. the method case-sensitive . as far can tell, nginx doing right thing according specification. if disagree, you'll have explain think it's doing wrong more clearly. edit: yes, agree answer @julianreschke, should return 501 status code, not 400, catch.
