for following example, public abstract class recorddata { private mydate mdate = new mydate(new simpledateformat(""yyyy-mm-dd hh:mm:ss")); public date getmydate() { return mdate.getdate(); } ..... } i implementing classes override date format. 1 way of doing have method this: protected simpledateformat getdateform() { return new simpledateformat("yyyy-mm-dd hh:mm:ss") } so,the initialization should like: mydate mdate = new mydate(getdateform()); is there other convenient way of doing this. potential issues above implementation. doing bad idea: base class call methog of subclass in constructor, , call method on object hasn't been initialized yet. you'd better pass data needed superclass in constructor: public abstract class recorddata { private mydate mdate; protected recorddata(string datepattern) { this.mdate = new mydate(new simpledateformat(datepattern)); } } doing how others

i using following code load youtube video. jquery(document).ready(function() { $("#load").click(function(){ data = '<iframe id="placeholder"> </iframe>'; $('#putithere').html (data); $('#putithere').show (); document.getelementbyid ('placeholder').src='http://www.youtube.com/embed/7r4ljq7-_6y'; }); }); additional buttons exist well. problem on ipad or iphone, other buttons frozen (do not respond touch) until video started. once started, other buttons function. occurs in 'touch' environment. using 'click' environment, buttons not frozen. so, example on lap top (using mouse), can load video, see wrong one, , click load different video. on ipad, can not click (touch) load different video until loaded video has started play. this has been logged bug youtube api, affects ipod/ipad/iphone family links directly underneath embedded youtube video not work same hei

there global codes not valid according w3c standards example can consider youtube embed code or facebook plugins. in such cases, shall do? <iframe width="560" height="315" src="http://www.youtube.com/embed/6mxng9hsyyo" frameborder="0" allowfullscreen></iframe> what suggest me in such cases? edit codes ensure w3c validation or leave these when entire website w3c validated? best regards, touhid the validation error given (when checking in html5) is: the frameborder attribute on iframe element obsolete. use css instead. basically means frameborder no longer supported in html5 (and can achieved through css). reason still included, however, because not browsers have html5 support - works fall-back. you shouldn't have problems removing attribute if want site pass validation tests, it's unlikely issues ever arise leaving attribute there.

this question has answer here: why not possible overload class templates? 2 answers it function overloading. e.g. ok this: void foo(int i) { ; } // function overload ftw. void foo(int i, int j) { ; } but not (yet) ok this: template<typename t> class foo { }; // fail! template<typename t1, typename t2> class foo { }; does feature not exist in order avoid confusion? or there reason wouldn't make sense? no not possible in c++ that. the template looked first, parameters make impossible know template which. it seem duplicate one: why not possible overload class templates?

in mpi application have distributed array of floats , 2 "parallel" arrays of integers: each float value there 2 associated integers describe corresponding value. sake of cache-efficiency want treat them 3 different arrays, i.e. structure of arrays, rather array of structures. now, have gather these values first node. can in 1 communication instruction, defining mpi type, corresponding structure, 1 float , 2 integers. force me use array of structures pattern instead of structure of arrays one. so, can choose between: performing 3 different communications, 1 each array , keep efficient structure of arrays arrangement defining mpi type, perform single communication, , deal resulting array of structures adjusting algorithm or rearranging data do know third option allow me have best of both worlds, i.e. having single communication , keeping cache-efficient configuration? you take take @ packing , unpacking. http://www.mpi-forum.org/docs/mpi-11-html/nod

i have arduino project (it's mintduino, it's same microcontroller) has 3 buttons, setup tutorial ( http://arduino.cc/en/tutorial/buttonstatechange ) common + , - between them. buttons individually connected a0, a1, , a2. here code use read them: void setup() { pinmode(a0, input); pinmode(a1, input); pinmode(a2, input); serial.begin(9600); } void loop() { serial.print("b1: "); serial.print(digitalread(a0)); serial.print(" b2: "); serial.print(digitalread(a1)); serial.print(" b3: "); serial.print(digitalread(a2)); serial.println(""); } when button unpressed, get: b1: 1 b2: 1 b3: 1 and when press any button, get: b1: 0 b2: 0 b3: 0 so can tell button pressed, , can not tell button was pressed. how can tell 1 button press another? i think know why it's happening, can't think of solution doesn't involve using 3 different batteries can individual circuits. most got wiring wron

suppose have text based training data , testing data. more specific, have 2 data sets - training , testing - , both of them have 1 column contains text , of interest job @ hand. i used tm package in r process text column in training data set. after removing white spaces, punctuation, , stop words, stemmed corpus , created document term matrix of 1 grams containing frequency/count of words in each document. took pre-determined cut-off of, say, 50 , kept terms have count of greater 50. following this, train a, say, glmnet model using dtm , dependent variable (which present in training data). runs smooth , easy till now. however, how proceed when want score/predict model on testing data or new data might come in future? specifically, trying find out how create exact dtm on new data? if new data set not have of similar words original training data terms should have count of 0 (which fine). want able replicate exact same dtm (in terms of structure) on new corpus. any ideas/

my question if have thread program runs in infinite loop , each loop simulation step, @ every loop there might request timer something. sounds easy confusing thing want loop continue , not wait timer , "do something" statement happen if timer fired. clarification: class thread1(threading.thread): def __init__(slef): threading.thread.__init__(self) def run(self): while true: #do step 1 #do step 2 #if input available:>start_timer(seconds) #if timer(user input seconds) finished step 3 #continue looping again problem have i've tried use timer threading library (from threading import timer) show execution error, while sleep function sleeps , whole simulation stops wont good.

i have created c++11 class in want parse string , return object based on data in string. object want return defined as: // container topic data , id template <typename t> class topic { public: topic(string id, t data) : _id(id), _data(data) {} private: string _id; t _data; }; the function returns object defined as: // parses string , splits components class topicparser { public: template <class t> static topic<t> parse(string message) { t data; // string, vector<string> or map<string, string> string id = "123"; topic<t> t(id, data); return t; } }; i (think i) able call function in way: string message = "some message parse..."; auto = topicparser::parse<topic<vector<string>>>(message); auto b = topicparser::parse<topic<string>>(message); but compiler complains that: no matching function call ‘topic<std::vector<std::basic_string<char&

it possible has been answered somewhere couldn't find it. appreciate if me sql statement again. this sql statement have far: select * , round( (rate * time_to_sec( total ) /3600 ) , 2) revenue (select event.eventid, event.staffid, event.role, timediff( time, pause ) total, case when position = 'teamleader' (teamleader) when position = 'waiter' (waiter) else '0' end rate event, rates, eventoverview storno =0 , event.eventid= eventoverview.eventid , event.clientid = rates.clientid group event.eventid, event.clientid)q1 group q1.staffid the table getting giving me total rate per staff , event. achieve sum of rates per staff. sum of revenue. hope can me. in advance you can enclose query in subquery , in outer query this: select *, sum(revenue) ( select * , round( (rate * time_to_sec( total ) /3600 ) , 2) revenue ( select event.eventid, event.staffid, event.role, time

how take join of 2 record sets using map reduce ? of solutions including posted on suggest emit records based on common key , in reducer add them hashmap , take cross product. (eg. join of 2 datasets in mapreduce/hadoop ) this solution , works majority of cases in case issue rather different. dealing data has got billions of records , taking cross product of 2 sets impossible because in many cases hashmap end having few million objects. encounter heap space error. i need more efficient solution. whole point of mr deal high amount of data want know if there solution can me avoid issue. don't know if still relevant anyone, facing similar issue these days. intention use key-value store, cassandra, , use cross product. means: when running on line of type a, key in cassandra. if exists - merge records existing value (b elements). if not - create key, , add elements value. when running on line of type b, key in cassandra. if exists - merge b records existing value (a

i have layout have 2 rows of 4 boxes on top of each other standard layout. want change layout on mobile devices (media-screen), in single row (i.e. 8 boxes on same line), extending off right edge of screen. user can swipe horizontally (pushing row of content off left side of screen) browse through it? each box div (clicking each box reveals more content within box) , think re-aligning them easy enough (display: inline-block), don't know how extend off screen when scroll horizontally, doesn't move whole page - moves content across viewing area. the effect i'm trying achieve bit similar how group of photos displayed on news feed on ios facebook app (ipad @ least). any tips on making possible appreciated.
