in restful spring mvc app, efficient way limit user's ability update domain objects? imagine movie service following url: "service/movie/id". there 2 groups of users, admins , basic users. while admins can use put request update properties of movie dto, basic users may update subset of them. what best way implement spring security? i have considered having separate urls admins , basic users, seems inelegant. you can use @preauthorize annotation checking roles. check out if it's need. http://static.springsource.org/spring-security/site/docs/3.0.x/reference/el-access.html#el-pre-post-annotations update can use @preauthorize("hasrole('role_user','role_admin')") multiple roles.

i have cassandra 1.2 cluster using vnodes (default of 256 per node). i'd predict placement of these vnodes physically within ring within client can more efficiently select coordinator node per query. i know vnodes randomly spread around ring i'd need query cassandra @ least once per client instance. any idea if it's possible? cassandra-sharp has looks stubbed class selecting endpoint it's row key: tokenawarestrategy. far can tell has no partitioning logic. has done before? alex cqlsharp has working implementation of tokenaware strategy. see cqlsharp wiki on details how use it. the datastax .net driver under heavy development. i've seen working on same kind of logic, unsure current state is.

assuming 1 has 3 tables in relational database : customer(id, name, city), product(id, name, price), orders(cust_id, prod_id, date) my first question best way excecute query: "get customers ordered product". people propose query exists as: select * customer c exists (select cust_id orders o c.id=o.cust_id) is above query equivalent (can written?) as: select * customer exists (select cust_id orders o join customer c on c.id=o.cust_id) what problem when use in instead of exists apart performance as: select * customer customer.id in (select o.cust_id order o ) do 3 above queries return same records? update: how exists evaluation works in second query (or first), considering checks if subquery returns true or false? "interpretation" of query i.e.? select * customer c exists (true) the first 2 queries different. the first has correlated subquery , return want -- information customers have order. the second has uncorrelated sub...

i'm trying change test pattern of ffmpeg streamer, trouble syncing libavformat/ffmpeg x264 , rtp , familiar rgb format. broader goal compute frames of streamed video on fly. so replaced av_pix_fmt_monowhite av_pix_fmt_rgb24 , "packed rgb 8:8:8, 24bpp, rgbrgb..." according http://libav.org/doxygen/master/pixfmt_8h.html . to stuff pixel array called data , i've tried many variations on for (int y=0; y<height; ++y) { (int x=0; x<width; ++x) { uint8_t* rgb = data + ((y*width + x) *3); const double = x/double(width); // const double j = y/double(height); rgb[0] = 255*i; rgb[1] = 0; rgb[2] = 255*(1-i); } } at height x width = 80x60, version yields , when expect single blue-to-red horizontal gradient. 640x480 yields same 4-column pattern, far more horizontal stripes. 640x640, 160x160, etc, yield three columns, cyan-ish / magenta-ish / yellow-ish, same kind of horizontal stripiness. vertical gradients behave more weirdly...

using: mysql server. i'm in situation need check if customerid exists before registering user in batch application. the problem different thread/process of same batch application can trying check if same user registered or not, , try create if not exist. after reading understand store procedure (createcustomer) select check if customerid not exists , calls insert register customer right way. if 10 batch processes try calling createcustomer store procedure same customerid @ same time ? happen in case ? possible same user created 10 times here ?

i've been given ui uses uitabbarcontroller , , in 1 of tabbed viewcontrollers , view (an arrow uiimageview ) needs positioned relative tab indicator (the arrow needs point down @ indicator, centered along x-axis). used basic math emulate position based on known variables, , works iphone/pod in both landscape , portrait orientations, fails on ipad (it's little far right in both orientations - seems worse in landscape might perception). here's used: int visiblewidth = self.view.frame.size.width; int tabbarsize = self.tabbarcontroller.tabbar.frame.size.width; int tabsize = tabbarsize / [self.tabbarcontroller.viewcontrollers count]; int tabposition = 2; // hint should point @ 3rd tab int arrowiconwidth = hinticon.image.size.width; int arrowiconheight = hinticon.image.size.height; int tabemulationposition = visiblewidth / 2 - tabbarsize / 2; int taboffsetposition = tabemulationposition + ( tabsize * tabposition ); int iconposition = taboffsetposition + ( tabsize / 2 -...

i have durandal routes configured below. var routes = [ ....... more routes here..... { url: 'login', moduleid: 'viewmodels/login', name: 'log in', visible: true, caption: 'log in' }, { url: 'logout', moduleid: 'viewmodels/logout', name: 'log out', visible: false, caption: 'log out' }, { url: 'register', moduleid: 'viewmodels/register', name: 'register', visible: false, caption: 'register' }]; and working expected. able activate logout route in navigation when log in , log in button become invisible. have tried following code , despite not throwing errors not change visibility of in interface. var isloggedin = ko.observable(false); isloggedin.subscribe(function (newvalue) { var routes = router.allroutes(); if (newvalue == true) { (var k = 0; k < routes.length; k++) { if (routes[k].url == ...

i'm coming java background, , needed app realtime data , push. i'm thinking of using meteor since seems easier way use node.js. my question need learn node.js before starting meteor ? , meteor suitable production application (i know haven't reached 1.0, experiences think) thank you. meteor not require knowing node.js in order build applications, long stay within boundaries of meteor abstracts away you. meteor young, "production-ready" depends on application is. write real-time banking application right now? no. ready mvps, demos, , straightforward consumer applications? sure, long understand limitations.

i have directed graph represented this: arc(1, 2). arc(1, 4). arc(1, 5). arc(3, 2). arc(3, 7). arc(4, 3). arc(5, 6). arc(6, 8). arc(7, 6). arc(9, 8). what need predicate put inside list nodes can go specific node. example node 1 resulted list should l=[2,4,5] because 1 can go 2,4 , 5. doesn't matter how done, matters result, nodes must in list. have tried in couple of ways failed. an example of how tried it: road(x,l,l2):- arc(x,y), not(belong(y,l)), append(l,[y],l2), road(x,l2,_). road(x,l,l). belong(y,l) predicate returns true if y found inside of l . , example when run road(1,[],l). result l=[2] , normal because predicate not written. when try make using recursion don't know put right stop recursion, hope understand want say. , tried way using fail didn't worked neither , don't remember how made it. hope can come solution fast :), in advance. your code need fair amount of corrections: here working version. road(x,l,l2) :- arc(x,...

i'm having issue unique events , total events. don't understand why unique events greater total events (image attached: https://analytics-a-googleproductforums-com.googlegroups.com/attach/584c3c65bd24cfec/screenshot%20at%202013-05-14%2017:00:40.png?gda=9qkpguyaaadqflbdoux1kz9vp-6pb8mh0qevsnjbcwpb2zqmxh9r_fqjw8mf6kyuxitghb4bde5x40jamwa1uurqdcgharkee-ea7gxymt0t6ny0uv5fiq&view=1&part=4 ). someone can explain how posible? santiago vázquez found thing: see "unique events" great "total events" when @ event category or action, put "event label" secondary dimension , event has been triggered times no label input. google analytics hasn't option "(not set)" particular dimension, doesn't show events in total events count, still counts "unique events" users executed particular event category / action.

hi point in right direction question. i'm trying fathom object orientated javascript, having trouble getting head around binding dom elements objects. i make little animated widget type thing web page. widget simple drop down tabs , (like tabs actual folder) want tab drop down bit mouseover event raise mouseout. here current implementation, doesnt work @ moment it's mock http://bombinglish.com/ i want make class tabs , include open , close animation methods, methos add events, , other necessary fields. instanciate new object each tab. how do tell each object must must respond corresponding mouse events, or put way how bind dom element object? if using javascript presentation logic, don't think it's worth try , wild oo. if have @ top of every page, label tabs unique class name. in javascript file bind mouseover event on every dom element class name. perhaps, others have differing opinions on however.
