i want know if there java api available convert pojo object json object , vice versa. yes, there json.org. take @ http://www.json.org/java/index.html [edited] imagine have simple java class this: public class person { private string name; private integer age; public string getname() { return this.name; } public void setname( string name ) { this.name = name; } public integer getage() { return this.age; } public void setage( integer age ) { this.age = age; } } so, transform json object, it's simple. this: import org.json.jsonobject; public class jsontest { public static void main( string[] args ) { person person = new person(); person.setname( "person name" ); person.setage( 666 ); jsonobject jsonobj = new jsonobject( person ); system.out.println( jsonobj ); } } hope helps. [edited] here there other example, in case using jackson: https://brunozambiazi.wordpress.com/201

after android apps installed, found change odex file (not apk ) in smartphone. how happens? can teach me, interested it. the blog article right, not complete. have full understanding of odex file does, have understand little how application files (apk) work. applications glorified zip archives. java code stored in file called classes.dex , file parsed dalvik jvm , cache of processed classes.dex file stored in phone's dalvik cache. an odex pre-processed version of application's classes.dex execution-ready dalvik. when application odexed, classes.dex removed apk archive , not write dalvik cache. application not odexed ends 2 copies of classes.dex file--the packaged 1 in apk, , processed 1 in dalvik cache. takes little longer launch first time since dalvik has extract , process classes.dex file. if building custom rom, it's idea odex both framework jar files , stock apps in order maximize internal storage space user-installed apps. if want theme, deodex

so want have feature like: "random post of hour" website, post object model. having db choose random post per request can expensive don't want pick row on every request. don't mind if different users have different "random post of day". i go , cache query, getting memcache involved feels hacky overkill. creating table , job 1 value. is there way have global variable periodically set in django? thank you! went eduardo's solution use memcached: https://docs.djangoproject.com/en/1.3/topics/cache/#the-low-level-cache-api

i using r-project deal statistics, due amount of resources needed, r struggling while pascal way faster. there way use pascal code in r-project? if can compile dll (windows) or .so (unix) file might able use same mechanism used c , fortran. load dll/.so dyn.load() function , call .c("functionname"). however, dependent on operating system, compiler, , code. r helps fortran , c programmers providing shlib command. 1 does: r cmd shlib foo.f and gets foo.so back. dyn.load("foo.so") , can call fortran code .c("subname",as.integer(1),as.double(pi)) , on. perhaps if can convert pascal c (is there 'p2c' converter?).

i have self reference table store hierarchical values in order show them in treeview or on ,according james crowley article ( tree structures in asp.net , sql server ) our table this: id parentid name depth lineage 1 null root node 0 /1/ 2 1 child 1 /1/2/ 3 1 child b 1 /1/3/ 4 1 child c 1 /1/4/ 5 2 child d 2 /1/2/5/ to path of node (for example id=5) suggest following query against table select * dftree (select lineage dftree id = 5) lineage + '%' result : id parentid name depth lineage 1 null root node 0 /1/ 2 1 child 1 /1/2/ 5 2 child d 2 /1/2/5/ and acceptable but how have result set when there multiple ids want have path ? therefore example in above example instead of id=5 pass multiple values : select * dftree

i'm getting jquery , notice strange behavior in way of code executed. when execute function based on click action, function runs twice, first time "undefined" value click , second expected value. end result code "works" want understand i'm doing wrong causing unexpected behavior. here's jquery code: $(function() { //$('#venue').buttonset().click(function(event, ui) { //$( '#venue' ).buttonset().live('click', function (event, ui) { $('#venue').buttonset().unbind('click').bind('click', function(event, ui) { var venuename = $("input[name='venue']:checked").val(); if (venuename == "venue2") { alert("about deselect, venue: " + venuename); $("#meallist option[value='dinner']").removeattr("selected"); } else { alert("doing nothing, venue: " + venuename); } }); }); note 3 different w

i have rails app uses mysql, mongodb, nodejs (and socketio). right now, app (everything) hosted inside 1 box. know should when number of users grow. factors should take account determine whether need host separate element in box (like mysql, node, mongo in each of separate box). should make 1 single box bigger? there best-practice method can go with? if guys can provide me reference, guides, research regarding topic. please do. super noob @ deployment , server configuration. the short answer move own box. longer answer is: depends on app's usage. i recommend use nagios or similar monitor app's resource utilization -- is, how cpu , ram each of services use. when 1 starts each resources (and page load speed negatively affected), move own box. then continue monitor box, beef when necessary or shard out. the high scalability blog reading on other people have done.

i'm plotting data using geom_smooth , looking way change color of standard error shading each line match line (ie., red line have it's standard error shaded red). i've looked through official ggplot2 documentation list of opts() @ https://github.com/hadley/ggplot2/wiki/%2bopts%28%29-list . advice (or confirmation of whether or not it's possible) appreciated. your (understandable) mistake think should changing color rather fill . standard error shadings made geom_ribbon essentially, , 2d area, "color" "filled" determined fill , not colour . try: geom_smooth(aes(...,fill = variable)) where variable same 1 map colour elsewhere.

i building web page uses slidejs image slider show series of images. when run page firefox , safari page looks way should. however, when run same code within msie 9, looks horrible. ie putting borders around slidejs images , buttons. went through css , turned off every border find, still msie makes terrible. page: http://107.22.173.10/print.html user: test2 login: abc111 any ideas why happening , how can fix it? remove border in css b/c ie typically adds borders image href's... below should work: a img {border: none; } most people use reset stylesheet correct issues , others before using own css.

i trying understand function does. can explain me? function newinstance (class) local o = {} setmetatable (o, class) class.__index = class return o end it called this: self = newinstance (self) this function apparently serves provide variant of oop in lua (a bit sloppy in opinion). this factory class. it may rewritten follows, clarity: c = { } c.foo = function(self) -- method, class not empty print("foo method called", tostring(self)) end c.__index = c -- (a) function newinstance(class) return setmetatable({ }, class) -- (b) end now if create 2 new instances of c, see both have method foo(), different self: o1 = newinstance(c) o1:foo() --> foo method called table: 0x7fb3ea408ce0 o2 = newinstance(c) o2:foo() --> foo method called table: 0x7fb3ea4072f0 the foo methods same: print(o1.foo, o2.foo, o1.foo == o2.foo , "equal" or "different") --> function: 0x7fb3ea410760 function: 0x7fb3ea4107

what have read, passing arguments default valuetypes. in example first function test1 takes reference type , unbox, decrease performance if got right. have never read test2 increase performance. so whats best practice? public main(){ string test = "hello"; test1(test); // line perform boxing? it's not performance? test2(ref test); // passing reference reference } public string test1(string arg1) { return arg1; } public string test2(ref string arg1) { return arg1; } there's no boxing or unboxing involved @ here. string reference type - why boxed? mean? even if used int instead, there'd no need boxing, because there's no conversion of value actual object. i suspect understanding of both boxing , parameter passing flawed. boxing occurs when value type value needs converted object, in order used variable (somewhere) of interface or object type. this boxes: int value = 10; foo(value); ... public void foo(object

i'm working class derived uitabbarcontroller @ present. when load tab bar topmost view during appdelegate setup constructor called first, , then, after construction complete, viewdidload invoked. however, if create tab view controller later in app (e.g. second or third "page"), virtual viewdidload call made during construction of uitabbarcontroller. isn't causing virtual function table problems (the child class being invoked) causing particular problems me because can't access construction parameters in viewdidload. as workaround, i'm detecting firing of viewdidload() , adding later call during own constructor. i'd quite understand going on: why uitabbarcontroller call viewdidload during construction?

what's preferred practice compile-run cycle in emacs? previously, used m-x compile (mapped f12 ) make compile command. within makefile had entry run program compiled. worked fine when programs non-interactive, compilation buffer non-interactive. of course open shell , run executable, i'd automate compile-run cycle as possible , assume there must standard practice , i'm guessing executing-from-the-makefile method kluge... c-u f12 works, i'm wondering if that's best approach doing (and if so, how can bind f12 equivalent c-u m-x compile instead of m-x compile ?). it can't simpler c-u m-x compile . have makefile task defined. you're asking how map f12? try this: (defun compile-interactive () (interactive) (setq current-prefix-arg '(4)) (call-interactively 'compile)) (global-set-key (kbd "<f12>") 'compile-interactive) you should read interactive options , optional arguments sections of manual.

i'm copying html old website new one. i'm getting bunch of issues this: city�s the apostrophe wrong. i know when, copying text microsoft word, need strip garbage pasting notepad copying stripped version site. there way can reformat pages need moved? thanks! did change encoding of website? maybe had <meta http-equiv="content-type" content="text/html;charset=utf-8"> , didn't include <meta> tag new site. there many encoding possibilities (iso-8859-1, utf-8, windows-1250 , several others...) have choose correct 1 site. general it's decision use utf-8 without bom, since every browser understands utf-8 , many text editors (e.g. notepad++, vim) provide command convert ansi or iso-8859-1 documents utf-8.

i'm trying write ssl-based async server using boost asio example code here . i first message , response correctly @ client side. then, send second message received fine @ server, when response sent client. comes gibberish. i have uploaded server code pastebin . also, find below: // file - server.h class server { public: explicit server(const std::string &address, int port, std::size_t threadpoolsize); // run io_service loop void run(); // stop server void stop(); private: //handle async accept operation void handleaccept(const boost::system::error_code &e); // number of threads in thread pool std::size_t _threadpoolsize; // io_service boost::asio::io_service _ioservice; // acceptor listen incoming connections boost::asio::ip::tcp::acceptor _acceptor; std::string get_password() { return "password"; } // ssl context boost::asio::ssl

i have many incoming tasks of priority a , b , c , want handle tasks thread pool on multicore cpu. 70% of cpu should used process 'type a ' tasks, 20% of cpu 'type b ' tasks , 10% of cpu 'type c ' tasks. if however, tasks of 'type c ' arrive, 100% of cpu should devoted them. if task b , c arirve 66% proccess task b , 33% task c , etc... how implement in java? p.s: priority queue won't work because type tasks processed. also, assigning priorities threads wont work because not accurate. maybe should use 3 pools of threads then. 1 pool of 7 threads tasks, 1 pool of 2 threads b tasks, , 1 pool of 1 thread c tasks. edit: have parallelism if there c tasks (or, if have many processors, if have b , c tasks), multiply number of threads in each pool number of processors, or number of processors + 1, or other bigger factor like.

i have simple (i think) question : i got iphone. create plist file , save it. want upload file on server. then, 3 others iphone, download plist file , decrypt informations. my question : how can upload plist file server !! don't have ftp server or others ... can use instead dropbox exemple ? or other way communicate between iphone (private - not appstore) ? thanks answers ! yes, can use dropbox api upload plist on dropbox user's folder. check first this link setup project you can use these snippets ( from page ): nsstring *localpath = [[nsbundle mainbundle] pathforresource:@"info" oftype:@"plist"]; nsstring *filename = @"info.plist"; nsstring *destdir = @"/"; [[self restclient] uploadfile:filename topath:destdir withparentrev:nil frompath:localpath]; then implement callbacks - (void)restclient:(dbrestclient*)client uploadedfile:(nsstring*)destpath from:(nsstring*)srcpath metadata:
