the code below throws exception in "return list;" typemismatch . suposed not to. public class teste { public <s extends testpai> s getlist(){ testpai list = new testefilho(); return list; } } class testefilho implements testpai{ } interface testpai{ } i found soluction it, puting this public class teste { @suppresswarnings("unchecked") public <s extends testpai> s getlist(){ testpai list = new testefilho(); return (s)list; } } class testefilho implements testpai{ } interface testpai{ } but sounds weird , since have other codes compiled before arent performing that. - im using eclipse ide in windows machine jre1.7.0_51 execution environment. can make works expected (in first code). thanks in advance. all types fixed! you're not using type parameter @ all. simplest way just public testpai getlist(){ testpai list = new testefilho(); return list; }

i have model called shop whos schema looks this: 'use strict'; var mongoose = require('mongoose'), schema = mongoose.schema; var shopschema = new schema({ name: { type: string, required: true }, address: { type: string, required: true }, description: string, stock: { type: number, default: 100 }, latitude: { type: number, required: true }, longitude: { type: number, required: true }, image: string, link: string, tags: [{ type: schema.objectid, ref: 'tag' }], createdat: { type: date, default: date.now }, updatedat: { type: date, default: date.now } }); module.exports = mongoose.model('shop', shopschema); i want use array tags reference model via objectid obviously. set works fine when add ids property via db.shops.update({...}, {$set: {tags: ...}}) , ids set properly. when try via express.js controller assigned model, nothing gets updated , there no error message. here update function in controller: // updates ex

i have 2 sets of points, called path , centers . each point in path , efficient method finding id of closest point in centers . in r. below simple reproducible example. set.seed(1) n <- 10000 x <- 100*cumprod(1 + rnorm(n, 0.0001, 0.002)) y <- 50*cumprod(1 + rnorm(n, 0.0001, 0.002)) path <- data.frame(cbind(x=x, y=y)) centers <- expand.grid(x=seq(0, 500,by=0.5) + rnorm(1001), y=seq(0, 500, by=0.2) + rnorm(2501)) centers$id <- seq(nrow(centers)) x , y coordinates. add column path data.frame has id of closest center given x , y co-ordinate. want of unique ids. my solution @ moment work, slow when scale of problem increases. more efficient. path$closest.id <- sapply(seq(nrow(path)), function(z){ tmp <- ((centers$x - path[z, 'x'])^2) + ((centers$y - path[z, 'y'])^2) as.numeric(centers[tmp == min(tmp), 'id']) }) output <- unique(path$closest.id) any on speeding appreciated. i think data.t

is persistence api similar jdbc? in other words, purpose connecting database? also, use sql? , advantage using persistence have on using jdbc? why not use jdbc? i've looked @ number of websites persistence yet still little confused , why using provide programmer advantage. short answers: the api referenced typically called "jpa" - that'll useful term search when have questions. yes, jpa replacement for/complement jdbc. typically you'll using jpa calls, can jdbc connection jpa implementations , use if need to. yes, uses sql under covers - it's client-layer abstraction around raw sql calls. the advantage allows use object-style interface when interacting database, , skip long, error-prone code related mapping db result columns fields in objects. myobject obj = em.find(somekey, ...); obj.getfoo(); obj.getbar(); is lot more maintainable string query = "select foo, bar, baz, wibble, whomp myobject_table pk_field = somekey";

as far can tell, search filter in navigator search available database names, not table names. if click on table name , start typing, appears simple search can performed beginning first letter of tables. i'm looking way able search table names in selected database. there can lot of tables sort through. seems feature there , can't find it. found out answer... if type example *.test_table or schema name instead of asterisk filter them. key schema/database must specified in search query. asterisk notation works table names well. example *.*test* filter table in schema test anywhere in table name.

a simple question have been having great difficulty finding definitive answer to: png files have dpi? or perhaps more importantly, relevant when building retina-enabled sites/apps? i've received psd assets our designer retina ipad app must convert html display within app. typically, receive such files 2048x1536 @ 72 dpi -- double size standard screen dpi. typically use css tell browser how display it. but time designer instructed provide psds @ 1024x768 @ 144 dpi (standard size double dpi.) believe incorrect, dpi setting within photoshop intended print purposes. plus, when save 144 dpi psd png or jpg, same 1 saved 72 dpi (or 30,000 dpi matter) psd. dpi doesn't seem reflected in either setting can see in resultant file nor in different file size. seems, @ best, metadata. so, it's understanding dpi isn't relevant here, , should asking double-sized assets retina projects, confirmation/clarity on issue before asking new assets. work many designers transitio

from understand, eatv (which datomic not have) great fit as-of queries. on other hand, see no use-case eavt. this analogous row/primary key access. docs : "the eavt index provides efficient access given entity. conceptually similar row access style in sql database, except entities can possess arbitrary attributes rather being limited predefined set of columns." the immutable time/history side of datomic motivating use case it, in general, it's still optimized around typical database operations, e.g. looking entity's attributes , values. update: datomic stores datoms (in segments) in index tree. navigate particular e's segment using tree , retrieve datoms e in segment, eavt datoms. comment, believe you're thinking of navigation of more b-tree structures @ each step, incorrect. once you've navigated e, accessing leaf segment of (sorted) datoms.

so trying define stack class, uses vectors make generic stack. reason when try create new stack receive error saying nothing was declared, understand saying nothing made, never made new object. did follow guide on how make generic stacks. http://www.tutorialspoint.com/cplusplus/cpp_templates.htm here stack class used: #ifndef stackers #define stackers #include <vector> #include "wrapper.hh" template <class t> class stack { private: vector<t*> elems; public: stack(); void push(t* obj); // push element t* pop(); t* peek(); // pop element t* findmax(); t* findmin(); bool isempty(); }; template <class t> bool stack<t>:: isempty(){ return elems.size()==0; } template <class t> void stack<t>::push (t* obj) { // append copy of passed element elems.push_back(obj); } template <class t> t* stack<t>::peek () { // append copy of passed element

i have below python code, no data received , program quits without running except clause print , return statements any ideas on happening? sock.settimeout(10) try: pkt = sock.recv(255) except socket.error: print "connection timed out!" return the problem socket.timeout exception different exception socket.error . so, except socket.error: doesn't catch socket.timeout same reason except valueerror: doesn't catch keyerror . (the documentation isn't obvious in 2.x. 1 of many things cleaned in python 3.3/pep 3151—see the nice new docs —but long you're sticking 2.x don't benefit that.) the right solution handle right error: sock.settimeout(10) try: pkt = sock.recv(255) except socket.timeout: print "connection timed out!" return if want handle socket errors (like, say, failure recv call) same way: sock.settimeout(10) try: pkt = sock.recv(255) except (socket.timeout, socket.error) e: print &

i have text file - $ abc defghjik here not $ not here go there $ .... i want extract text between 2 $ signs , put text list or dict. how can in python reading file? i tried regex gives me alternate values of text file: f1 = open('some.txt','r') lines = f1.read() x = re.findall(r'$(.*?)$', lines, re.dotall) i want output below - ['abc', 'defghjik', 'am here', 'not now'] ['you', 'are not', 'here go there'] sorry new python , trying learn, appreciated! thanks! in regular expressions $ character of special meaning , needs escaped match literal character. match multiple parts use lookahead (?=...) assertion assert matching literal $ character. >>> x = re.findall(r'(?s)\$\s*(.*?)(?=\$)', lines) >>> [i.splitlines() in x] [['abc', 'defghjik', 'am here', 'not now'], ['you', 'are not', 'here go there']]

this might seem stupid question, dont understand difference between these functions. setting both of these 0, why xxx() print 0,2,4,6,4,2,0 , xxy() print regular 0,1,2,3,4,5. question i'm asking is, why xxx() reduce after hits max value allowed '6' void xxx(int n) { cout << n; if (n < 5) { xxx(n + 2); cout << n;; } } void xxy(int n) { cout << n; if (n < 5) xxy(n + 1); } int main() { xxx(0); xxy(0); } well... pay atención here: cout << n; if (n < 5) { xxx(n + 2); cout << n; } when have recursive call xxx(n+2) current "iteration" stacked start new function. when function ends, previous iteration proceeds normally. therefore when max value (6) reached, iteration end continuing cout of previous "iteration"... in previous iteration n value 4... value displayed , iteration end continuing cout of n in previous iteration 2 , on... in

hey how can configure nginx block http attacks , xmlrpc attacks? thanks actually makes more sense: if ($http_user_agent ~ wordpress) { return 444; } returning status code 444 tell nginx not send response bad requests , close connection immediately. save lots of traffic , resources compared sending 403 page other response suggests. source: https://javapipe.com/block-wordpress-xml-rpc-ddos-attacks-with-nginx
