is there significant overhead (cpu, memory and/or io) in making repeat calls following function: public function getuuid() { return `uuidgen -r`; # -r = version 4 } versus using all php implementation of generating uuid (v4)? if matters project using apache (prefork mpm) 2.2.22 , php 5.3.10 (with apc ). my initial feeling benefit of doing generation of uuid in c library instead of in php more make system call overhead. additionally uuidgen being part of util-linux package inherently trust more php library generate uuids correctly, i'm keen input. i'd suggest profile problem. shell_exec() php function spawns shell, might not come cheap think. php class mention seems call subprocesses. did tests (on os x) , generate 10.000 uuids php class in minute, opposed 40 seconds shell_exec('uuidgen') . the php class seems call ifconfig in addition shell_exec() , might reason bigger overhead. also results vary hash algorithm choose.

i'm trying render large number of copies of same mesh in opengl. know can use small vertex buffer index buffer, each copy have it's own transformation matrix. want pass each matrix shader, vertices belonging same copy use same matrix. therefore, matrix buffer shorter vertex buffer. the mesh has 4 vertices, need somehow send new matrix every 4 vertices. ideas? you use instanced rendering: https://www.opengl.org/sdk/docs/man/html/gldrawarraysinstanced.xhtml or https://www.opengl.org/sdk/docs/man3/xhtml/gldrawelementsinstanced.xml you can create vbo filled transformation matrices each index. set divisor 4 matrix changes after 4 vertices have been sent: https://www.opengl.org/sdk/docs/man3/xhtml/glvertexattribdivisor.xml you can use gl_instanceid in vertex shader figure out instance being rendered, , can generate transformation matrix way rather sending every transformation matrix shaders.

i using laravel. have come across carbon there in vendors folder. did quick search , found great extension php date time. somewhere in application, needed logic check if given time falls between 2 points of time. lets say, want check if 10:00 falls under time time 9:55 , 10:05. surely, falls how should use logic of carbon. by default carbon::now() return date , time in 2014-12-02 14:37:18 format. thinking if extract time part i.e 14:37:18 can compare 2 times know whether time under testing falls under 2 points of time or not. if directly check 2 carbon objects, try check year well. need time part only. and matter of fact, not sure if times (h:m:s) can directly can compared or not through carbon. yes there way in carbon, take on documentation here . to determine if current instance between 2 other instances can use aptly named between() method. third parameter indicates if equal comparison should done. default true determines if between or equal boundaries.

i'm trying make simple rpg in dart. need show text on screen in div, , need make program wait user input before displaying next piece of text. for example: void main() { showtext("hello, adventurer! welcome land of dartia! (press enter continue...)"); print("showtext has finished"); } "showtext has finished" should not display until text has been displayed , player presses enter. here's (pretty ugly in opinion) code have far: void showtext(string text) { var textbox = queryselector("#sample_text_id") ..text = ""; var timer; var out; out = ([int = 0]) { textbox.text += text[i]; if (i < text.length - 1) timer = new timer(const duration(milliseconds: 10), () => out(i + 1)); }; out(); } the timer runs out() function asynchronously, don't want do. ideally write this: void showtext(string text) { var textbox = queryselector("#sample_text_id")

i playing new features of c# 6.0 i have following line of code public class circle(int radius) { public double circumference => 2 * 3.14 * radius; } above code doesn't work , gives error "the name radius doesn't exist in current context" but when use public class circle(int radius) { int radius = radius; public double circumference => 2 * 3.14 * radius; } code works fine. sort of bug vs ctp or wrong code. believe should able use parameter of primary constructor inside constructor whithout setting other variable. well , may doesn't answer question directly primary constructor has been withdrawn c# 6.0. see: changes language feature set , question: primary constructors no longer compile in vs2015 you trying code in visual studio 2014 ctp. need download , install new version of visual studio 2015 preview . (but first have un-install visual studio 2014 ctp) you may see latest: languages features in c# 6 , vb 14

i have devexpressgridcontrol. want use in 1 column of grid : repositorylookupedit. fill repositorylookupedit database question. question return 3 columns : idperson , name , idcity. colums : idperson , name have data idcity have set in appication. so - in gridcontrol column idcity has fildename : idcity, , columnedit : repositorylookupedit. - repositorylookupedit has displayvalue : cityname, , valuemember: idcity. and question is: when choose in grid in 1 row value of city , go row, value first row disaper. what doing wrong? give me advise? i use devexpress 9.2. this.gvperson = new devexpress.xtragrid.views.grid.gridview(); this.repluecity = new devexpress.xtraeditors.repository.repositoryitemlookupedit(); this.repluecity.columns.addrange(new devexpress.xtraeditors.controls.lookupcolumninfo[] { new devexpress.xtraeditors.controls.lookupcolumninfo("idcity", "idcity", 20, devexpress.utils.formattype.none, "", false, devexpress.ut

code used: int n = 0; int a[10] = null; for(int i=1;i<n;i++) { a[i] = driver.findelement(by.xpath(".//*[@id='steplist']/li[n]")).gettext(); system.out.println("/userid ="+a[i]); } please me convert string , int , , how can values of li , store in n ? you can elements have same xpath using findelements instead of findelement can this: webelement elements = driver.findelements(by.xpath(".//*[@id='steplist']/li")) for(webelement elem: elements) { a.add(elem.gettext()); } for excel can use jexcelapi

i have problem while unmarshalling xml mixed content. space gets lost. xml looks this: <text>rooms in <g>the</g> <g>eldorado hotel</g> on broadway have jacuzzi</text> this unmarshalled to: "rooms in " (with final space) a object value 'the' a object value 'eldorado hotel' " on broadway have jacuzzi" (with initial space) everything fine i'm missing space between 2 tags. need preserve space! the simplified mapping like: @xmltransient public abstract class abstracttext { private list words; @xmlmixed @xmlelementrefs({ @xmlelementref(type = wordgroup.class, required = false), // <g> tag @xmlelementref(type = word.class, required = false) }) public list getwords() { if (words == null) words = new arraylist(); return words; } public void setwords(list words) { this.words = words; } } @xmlroot public class text e

i have 3 dependent text boxes. is, department, class , subclass. when department fill class of inputtext enable , when preecho class subclass enable. make process not had difficulties. however, can not make reverse process when delete, example, value of department should put disable class , delete value. not because events, when empty not trigger new event , therefore not enter else if. text boxes have autosuggest behavior , class depends on chosen department , subclass of class. class , subclass have associated partialtriggers. my code of input text department (with valuechangelistener setdepartment()): public void setdepartment(valuechangeevent valuechangeevent) { dciteratorbinding dc2 = (dciteratorbinding)evaluteel("#{bindings.scpclassview1iterator}"); viewobject vo2 = dc2.getviewobject(); vo2.applyviewcriteria(vo2.getviewcriteriamanager().getviewcriteria("scpclassviewcriteria")); if (it7.getvalue() == null) {

i need set format class' date serialization. have version of jackson, doesn't have @jsonformat. that's why wrote custom class: public class cdjsondateserializer extends jsonserializer<date>{ @override public void serialize(date date, jsongenerator jsongenerator, serializerprovider provider) throws ioexception { simpledateformat dateformat = new simpledateformat("mm/dd/yyyy"); string datestring = dateformat.format(date); jsongenerator.writestring(datestring); } } and used it: @jsonserialize(using = cdjsondateserializer.class) private date startdate; but, have fields have different date's formats , don't want create classes serialization. can add needed formats constants cdjsondateserializer class , set needed format annotation @jsonserialize ? this: @jsonserialize(using = cdjsondateserializer.class, cdjsondateserializer.first_format) . after answer below: it works after corrections. i've changed way of getting ann
