here questions: when i'm printing area of both shapes, getting correct area ellipse , 0 circles . why? i have multiple radii of circle. how can keep on adding area, computed previous radius? in short, need sum area of radii. whenever pass radius of circle, need circle area (computed radius) should added ellipse area well. how that? this current code: public class ellipse { private double area; private double axis1; private double axis2; public ellipse() { area = 0; } public ellipse (double axis1, double axis2) { this.axis1 = axis1; this.axis2 = axis2; } public void calculatearea() { area += axis1 * axis2; } public double getarea() { return area; } } public class circle extends ellipse { private double radius; private double area; public circle(){ area = 0; } public circle(double radius) { super(radius, radius); } public double get

assume have 1 arithmetic function add 2 long variables , return long value. if pass long.maxvalue() argument wont give perfect result. solution that? code below explains mean: public class arithmaticexample { public static void main(string[] args) { system.out.println(arithmaticexample.addlong(long.max_value, long.max_value)); } public static long addlong(long a,long b){ return a+b; } } so can see wood trees, let's recast problem using byte rather long , consider byte = 0b01111111; // i.e. 127, largest value of `byte`. byte b = 0b01111111; byte c = (byte)(a + b); where need explicit cast circumvent conversion of a + b int . computing c hand gives 0b11111110 . is, of course, bitwise representation of -2 in 8 bit 2's complement type. so answer byte case -2. , same holds true long : there more 1 bits contend in addition. note although well-defined in java, same cannot said c , c++. if need add 2 long

every time describes elasticsearch re-indexing process assumed index accessed via alias. actual transition 1 index done changing said alias. application doesn't access alias actual index. on top of can't change index name application accessing. possible make transition old index new index using alias old index name, hence application not having know has changed? one problem face not allowed create alias has same name existing index (and vice versa). so if can't change app hitting , hitting index directly, cannot create index b alias a. the way it, to: copy/re-index index new index b delete index first and add alias onto index b (but during few seconds between 2 , 3, app hit nothing) it problem first time it, though. next time, you'll able switch alias index b (old) index c (new) atomically , app won't feel thing.

i use following wrapper in 1 of django models, unfortunately not know how due lack of sufficient information. run on machine djnago 1.9, tastypi via easy_install, apache via mod_wsgi , mysql. after installing these not know how proceed step 1, step 2 etc in order use demo code mentioned in above page , work successfully. further details type of fields , how used in grids.py (additional information) me lot. found author's github page unfortunately there no contact information in touch him. if knows it, delighted! regards

what's idiomatic way, if possible, of having go's filepath.walk return early? i'm writing function find nested directory of given name. using filepath.walk can't see way of terminating tree-walking find first match. func (*recursivefinder) find(needle string, haystack string) (result string, err error) { filepath.walk(haystack, func(path string, fi os.fileinfo, errin error) (errout error) { fmt.println(path) if fi.name() == needle { fmt.println("found " + path) result = path return nil } return }) return } you should return error walkfunc. make sure no real error has been returned, can use known error, io.eof . func find(needle string, haystack string) (result string, err error) { err = filepath.walk(haystack, filepath.walkfunc(func(path string, fi os.fileinfo, errin error) error { fmt.println(path) if fi.name() == needle {

i developing mobilefirst 7.0 hybrid app , i've implemented notification module ios , android platform. i using wl.client.push api , works fine on android platform gcm (android < 6.0 - on android 6.0 permission policy changed , it's similiar ios, have not tried on android 6.0 yet). i have problem ios. when try invoke wlclient.subscribe method when first start app on ios, subscribe method never invoked. can't find errors in logs on was, don't see response method- success or failure. thought problem related permission policy on ios, because when click allow notifications on native popup when app starting, subscribe() method still not invoked, when logging app second time method invoked. e.g. on ios 9.3.1 subscribe method when logging invoked , not :( i think it's random me , don't know, it's problem code, apns in country or problem mobilefirst push api? registernotifications.dosubscribe = function () { try{ wl.client.push.subscribe("m

these 2 functions perform extended euclidean algorithm, , find multiplicative inverse. order seems right, it's not coming i'm expecting per tool u of sydney http://magma.maths.usyd.edu.au/calc/ , since done in gf(2) finite field, think i'm missing key step translates base 10 field. this tested , worked on base 10, taking in polynomials binary coefficients might not possible here. question parts of python incorrectly applying algorithm, such // floor, may not carry function capable of in base 10 able in gf(2). the tool above can tested this: r<x>:=polynomialring(gf(2)); p:=x^13+x+1; q:=x^12+x; g,r,s:=xgcd(p,q); g eq r*p+s*q; g,r,s; the functions: def extendedeuclideangf2(self,a,b): # extended euclidean. a,b values 10110011... in integer form inita,initb=a,b; x,prevx=0,1; y,prevy = 1,0 while b != 0: q = int("{0:b}".format(a//b),2) a,b = b,int("{0:b}".format(a%b),2); x,prevx = (int("{0:b}"

let's have query: select product_id, price, price_day products price>10 and want join result of query (if example want in same row product's price , price in previous day) i can this: select * ( select product_id, price, price_day products price>10 ) r1 join ( select product_id, price, price_day products price>10 ) r2 on r1.product_id=r2.product_id , r1.price_day=r2.price_day-1 but can see copying original query, naming different name join result itself. another option create temp table have remember remove it. is there more elegant way join result of query itself? self join query help select a.product_id,a.price ,a.price_day ,b.price prevdayprice ,b.price_day prevday table1 inner join table1 b on a.product_id=b.product_id , a.price_day = b.price_day+1 a.price >10

i have been searching everywhere on how set icon image in java, , ends not working or gives me errors. here, in main method put code: public static void main(string[] args) { game game = new game(); // right here! game.frame.seticonimage(new imageicon("/icon.png").getimage()); game.frame.setresizable(false); game.frame.settitle(title); game.frame.add(game); game.frame.pack(); game.frame.setdefaultcloseoperation(jframe.exit_on_close); game.frame.setlocationrelativeto(null); game.frame.setvisible(true); } my path image "%project%/res/image.png" , use /image.png go ahead , access res folder (as have done in other parts of project) have converted icon file, , tried that, decides use default java icon. your problem due looking in wrong place image, or if classes , images in jar file, looking files files don't exist. suggest use resources rid of second problem. e.g., // path must relative *class* files s

i have gui program built using python 2.7 , pyqt4. want convert standalone windows executable. i went through docs pyinstaller-2.0 , tried several times think might on wrong approach. here structure of program.

so i'm experimenting using esri opensource example ( windy.js ) , rendering on openlayers 3 using similar the ol3 d3 example . windy.js renders wind-animating map on canvas. canvas size seems not change rendering performance. first, render windy.js canvas , update every 0.5 seconds: g_windy = new windy({ canvas: $("#canvas")[0], data: //some data }); //map ol3 map object function redraw() { windy.stop(); settimeout(function() { var mapsize = map.getsize(); var extent = map.getview().calculateextent(mapsize); extent = ol.proj.transformextent(extent, 'epsg:3857', 'epsg:4326'); var canvas_bounds = [ [0,0], [mapsize[0]*2, mapsize[1]*2] ]; var map_projected_bounds = [ [ extent[0], extent[1] ], [ extent[2], extent[3] ] ]; windy.start( canvas_bounds, mapsize[0]*2, mapsize[1]*2, map_projected

i'm building dashboard application, , i'd use angular-material instead of bootstrap . i'm not asking code or pre-made solutions here, need well-argumented points of view. i thinking using https://github.com/angular-dashboard-framework/angular-dashboard-framework or https://github.com/datatorrent/malhar-angular-dashboard framework dashboard, both based on bootstrap far know. i thinking modify them use angular-material instead of bootstrap , in case fail doing question : is better build dashboard scratch angular-material , or possible use angular-material , few bit of bootstrap widgets of dashboard only (which means menus , tabs based angular-material) ? i'm not affraid of starting scratch, don't want waste time. need both efficient , good-looking, thought i'd ask here first , here pieces of advice before starting. i'm not confident mixing bootstrap , angular-material read on internet untill now, maybe case might ok. well, shar
