i´ve been asked create report shows how many employees working in different departments during last trailing 12 months (mm-yyyy). i need print out every single month every combination of department, role_name , employee_code. i want print out results this: (assuming employee 234 joined company on sept 15 jr consultant in bsg department, promoted consultant in jan 16 , changed department in apr 16) date department role_name employee_code jun 16 cin consultant 234 mai 16 cin consultant 234 apr 16 cin consultant 234 mrz 16 bsg consultant 234 feb 16 bsg consultant 234 jan 16 bsg consultant 234 dez 15 bsg jr consultant 234 nov 15 bsg jr consultant 234 okt 15 bsg jr consultant 234 sep 15 bsg jr consultant 234 attached code. drop procedure if exists whileloop; procedure whileloop() begin declare date.date char; whileloop : loop if (date.date < date_format(prs.rpr_end_dt,

i'm writing script supposed remove redundant data points graph. data includes overlaps adjacent data sets , want data higher. (imagine 2 gaussians x offset overlap slightly. i'm interested in higher values in overlap region, final graph doesn't noisy when combine data in order make single spectrum.) here problems: 1) x values aren't same between 2 data sets, can't "at x, take max y value". they're close together, not equal. 2) distances between x values aren't equal. 3) data noisy, there can multiple points data sets intersect. , while gaussian higher after intersection gaussian b, noise means gaussian b might still have values higher. meaning can't "always take highest values in x area", because i'd wildly combine noise of both data sets. 4) have n overlaps of type, need efficient algorithm , can come somewhere @ o(n^3), "for each overlap, store data sets 2 arrays , each combination of data points (x0,y0) , (x1

i have created java desktop application stores encrypted files on desktop. have been tasked uploading word document encrypted application store on google cloud storage (free personal google cloud storage account). is possible, jar files needed , coding connect google cloud storage achieve this? or there better way of going doing this? you need store blob in google cloudstorage, can view configuration here: https://cloud.google.com/appengine/docs/java/blobstore/ for pourpouse , if have control on google account configuration, can upload documents drive account of app using drive api app engine, conmmunication it´s encripted it´s easier implement. problem have use allowed authentication oauth2

i have job , job b. job b triggered job a. not want job b start if there no code change in job b. use "poll scm" build trigger. how can make work? refrased question: job must trigger job b, job b must run when there scm changes job b. how configure this? so, job , job b have different code bases, somehow related , thus, dependency between jobs exists. downstream-ext plugin can this: supports "extended configuration triggering downstream builds: trigger build if downstream job has scm changes".

i have following code log(config.render()) however if have passwords in config they'll appear in log. there easy way eliminate this? looking that log(config.map { if ("password" in it.key.tolowercase()) "***" else it.value } .render()) for clear solution this val contenthiddenvalue = configvaluefactory.fromanyref("***", "content hidden") log.info(config.root() .withoutkey("security") .withvalue("security", contenthiddenvalue) .render()) the obvious disadvantage hides exact config subtree

i'm trying understand when compilers should value initialize arrays , when should default initialize it. i'm trying 2 options: 1 raw array, array aggregated in struct: const int n = 1000; struct { uint32_t arr[n]; a() = default; }; void print(uint32_t* arr, const std::string& message) { std::cout << message << ": " << (std::count(arr, arr + n, 0) == n ? "all zeros" : "garbage") << std::endl; } int main() { uint32_t arrdefault[n]; print(arrdefault, "automatic array, default initialization"); uint32_t arrvalue[n] = {}; print(arrvalue, "automatic array, value initialization"); uint32_t* parrdefault = new uint32_t[n]; print(parrdefault, " dynamic array, default initialization"); uint32_t* parrvalue = new uint32_t[n](); print(parrvalue, " dynamic array, value initialization"); structdefault; print(structdefault.arr, "automatic

i try build crf++ in visual studio 2013 , error in last line: array_[begin + siblings[i].code].base = value_ ? static_cast<array_type_>(-value_[siblings[i].left]-1) : static_cast<array_type_>(-siblings[i].left-1); error c4146: unary minus operator applied unsigned type, result still unsigned specifically, in darts.h, line 189. i built again in visual studio 2015 there no error. how can fix in visual studio 2013? try this: int tmp = static_cast<int>(siblings[i].left); array_[begin + siblings[i].code].base = value_ ? static_cast<array_type_>(-value_[siblings[i].left]-1) : static_cast<array_type_>(-tmp - 1);

i'm looking way retrieve array without last element, , without being mutated. _.remove mutate array , searches value not index (even if asked there ) _.without searches value, not index i have _.filter(array, function(el, i) { return != array.length -1}); siouf, not explicit , needs array stored somewhere. thanks i looking "butlast", found initial , job: var xs = [1, 2, 3, 4]; var xs2 = _.initial(xs); console.log(xs, xs2); // [1, 2, 3, 4] [1, 2, 3]

new angular, hope asking question correctly. (angular 1.5 , using components) parent.html: <names on-refresh-names='$ctrl.reloadnames'></names> parent.js this.reloadnames = function() { ... } names.html <input ng-model="searchnamevalue"> <button ng-click='$ctrl.onrefreshnames()'></button> names.js ... component.bindings = { onrefreshnames: '&' } i want make input search string cleared ( searchnamevalue = ''; ) when onrefreshnames executed. executed in parent , searchnamevalue in child. how can that? you can combine statements 1 expression: <button ng-click="$ctrl.onrefreshnames(); searchnamevalue = '';"></button> but in case makes sense move them both function in component controller: <input ng-model="$ctrl.searchnamevalue"> <button ng-click="$ctrl.onrefresh()"></button> where in controller this.on

i'd remove 3rd, 4th, 6th, 7th, 9th, etc th . thought like: summaryhead.find('tr:first th:nth-child(!3n+2)').remove; however doesn't work. tried summaryhead.find('tr:first th:nth-child(3n+3)').remove(); summaryhead.find('tr:first th:nth-child(3n+4)').remove(); this behaves rather weirdly. there way combine 2 finds? for clarity want remove of green , red fields in image, there might more or less rooms, each room have 3 fields, , want give first room's field colspan 3 , hide 2 fields (colored red & green here): i'm not sure if there nicer way can this summaryhead.find('tr:first th').filter(':nth-child(3n+3), :nth-child(3n+4)').remove();

i setting texttospeech use particular language (english - uk), using locale "en_gb". uses devices default language. there no way set programmatically? have downloaded files required language , when change tts's default language 'english - uk' works when default different programmatic approach not work. have scoured web best unable resolve issue. string ttsengine = "com.google.android.tts"; txt2speech = new texttospeech(this, this, ttsengine); //locale ttslocale = new locale("eng", "gbr"); txt2speech.setlanguage(new locale("en_gb")); tried several methods, none working. can not set tts's language programmatically? thank you edit: in response 'a honey bustard' other code: public class mainactivity extends appcompatactivity implements texttospeech.oninitlistener my oninit() public void oninit(int status) { // todo auto-generated method stub } also i'm calling .setlangu

in 1 of sites have thousands of visitors daily after 1 year, view count main video on start page still @ 26 views. i wanted save load times, that's why providing image play icon on page. icon gets clicked, load youtube iframe via: $('#introimg').click( function() { $(this).replacewith('<iframe width="759" height="426" src="https://www.youtube.com/embed/fdub8mivquk?wmode=transparent&amp;rel=0&amp;showinfo=1&amp;iv_load_policy=1&amp;modestbranding=1&amp;controls=2&amp;vq=large&amp;autoplay=1" allowfullscreen></iframe>'); }); i found one note here says: views originate result of clicking on 1 of native player ui elements (either play button in control bar or on static player image) count towards incrementing views video. is reason? because embed iframe autoplay true, there no click event. would workaround replacewidth , trigger('click')? (which not work

if create class , class intended accept specific type of data. proceed use generics , in class proceed have type constrained upper bound of number class. so class can use types of number class or subclasses of number (integer, double, long, etc). lets have array of these types , wish compare values in array. class contains array of these allowed data types, , wish compare these types only. we can using comparable interface contains compareto method. can use compareto method classes implement comparable interface. number 1 of classes implement interface. so if have class header specifies following: public class somename<t extends number> { this implies constraint of type t accept types of number or subclasses of number. if wanted use compareto method comparable interface, numbers class implements, t constrained to. if have method such as public t somename(t[] somevariable) { why can't method use compareto method?t constrainted number class, implements co
