i'm going developing online arcade html5/javascript games written in to-be-released ide. the game use ajax requests server record scores when people play these games. i theoretically have complete control on design of this, including mechanics of code logs high scores, game code, everything. i know it's never impossible hack client side games such or spoof high scores, want make difficult enough competent enough wont bothered enough (wishful thinking). i've read: how can prevent bogus high scores appearing on global high score list? which slightly different question html/js specific. my initial idea ajax request checks source of request correct location, simple , effective block hacking attempts. as previous answer stated cannot trust client, therefore best bet split game levels of sort , have server control level progression. if server tracking each client , progression can limit range of scores achievable. makes more tedious cheat client has

i'm afraid it's not possible, haven't found anywhere said impossible either. i'd include set of files within xml document using wildcards. this: <?xml version="1.0" encoding="utf-8"?> <mydocument> <!-- ... --> <xi:include href="*include.xml"/> </mydocument> i know doesn't work, think expresses intentions. there way achieve this? edit: i tried use xpointer attribute, couldn't make work. is possible use wildcards xinclude tags? no. href denotes uri, , these not have concept of wildcards. otherwise possible mirror google homepage saying href="http://www.google.com/*" . hint: file systems not have concept of wildcards. shells do. heavy lifting of filling in blanks when parse path , see * . underlying file system never gets see asterisk.

i rewriting client-server rich client database application (swing) three-tiered application netbeans rcp rich-client. by default hibernate , other jpa providers can used in very cumbersome way rich clients (native database connection not cutting through firewalls, loosing lazy-loading, conceptual problems managing session/entitymanager lifecycles...etc other problems). 1 needs kind of extension using them comfortably in rich clients. normally, rich clients call webservices in business logic tier (on server). usually, dedicated web-service methods handle crud operations of every object type. now, i wouldn't write custom web-service crud operations of each , every persistent class of application thought there may generic persistence web-service these kind of operations can handle @ least of crud operations of application. is there such persistence service??? here details of ideas/requirements: the service should work jpa-annotated pojos should use kind jpa p

this may obvious some, @ stage of putting spec , not have direct experience in setting openid server or consumer. we have central members' database used authentication, , number of satellite sites need authenticate users against members' database. intention use openid (one of standard php libraries) provide single-signon across group of sites. now, sites trusted. user logging in of sites should automatically trusted central authorisation site, , members details should passed across without question or further prompting. there no advantage exposing openid server other consumers group of trusted sites, if end doing that, usual requests permission , management screens presented user. so, going simple enough thing do, i.e. make these sites trusted server? "simple", asking whether fights against core principles or operation of openid. how openid key list of trusted sites - url consumer, or kind of coded "trust key" put unique user , consumer site? i

imagine common scenario: hacked cool project want share world. so: put on github, , fetch github on own website people can see demo. makes updating easy: push local box github, fetch on server. i'd track visitors add google analytics , maybe other site-specific stuff (like global header pages on site) project. however, checks out project github gets stuff too. there few solutions prevent that. make specific 'deployment branch' website, that's cumbersome. make kind of switch in code ( if ip === myip showstats() ), that's ugly. another option might use githooks, haven't got experience that. any other suggestions? people bothered when getting deployment-specific code in checkouts? similar breun's suggestion, (so question double answered) deploy python projects settings.py file defines settings needed on production machine.

i'm updating several image src attributes on page, , updated properly, when jquery updates items, page scrolls down items (they below 'fold') - how can stop page auto-scrolling down changes i'm making jquery? see same behavior ie , firefox // insert images current page $("img.nominphoto",$(".nominwrap")).each(function(){ var useritemid=$(this).attr("title"); $(this).attr("src",hashimageurls[useritemid]); }); thanks you may able fines using $(window).scrolltop , maybe hooking image's load method using .one() triggers releases (reset scrolltop when it's completed loading)--but hack @ best. if you're not (and assuming images fixed-height , width) it's "proper" specify width/height of image. allows renderer layout page (despite missing or updated content), prevents image(s) [re]loading having adverse effects later on.

i server side java programmer. in recent job search, have come across few postings mention : ' candidates expereince in algorithm development preferred'. refer to? posting bank...so not job research laboratory...just clarify bit. asked headhunter ...he not have idea this. when use java in applications, use apis implement algorithms...so technically not developing algorithms. right? "algorithm development" sounds vague. maybe original technical requirement knowledge of algorithms, , somewhere along way, thought didn't sound impressive enough, , rewrote "candidates experience in algorithm development preferred". i don't think means "the ability create new algorithms scratch". rather, need able recognize when program benefit use of known algorithm or data structure, or slight modification of one, , ability done. crucial skill on many projects, , speed important. the generic algorithms provided java class library (like arrays

might bit difficult understand based on description jsfiddle here: http://jsfiddle.net/n8a76/4/ basically want do, when click on of elements in first 3 boxes, want 1 element highlighted @ time. if click on 2 or 3 elements (names, projects, etc) right now, highlights 2 or three. unhighlights element when click again. so see, click element 1, element 1 highlighted. click element 2, element 1 (in same box) unhighlighted, , element 2 highlighted. so each box, code called dashed-panel , should independent of other. so in theory, john brown , jack's app ui highlighted @ same time. anyone have suggestions? you can remove class th sibling <tr> elements in same table, this: $(document).ready(function() { $('#clients table tr, #stages table tr, #projects table tr').click(function() { $(this).toggleclass('dash-elem-selected').siblings().removeclass('dash-elem-selected'); }); }); you can test out here , still allows toggl

how 1 check if mouse on hwnd? have tried using wm_mouseleave , wm_mousemove messages keep track, if click button , drag mouse out of button, doesn't receive wm_mouseleave until mouse released, late, because: when click button, wm_command message sent if: 1. mouse depressed on button 2. mouse on button 3. mouse released on button i need replicate functionality. to duplicate functionality, call setcapture() mouse messages sent window if mouse leaves it. can read current mouse position moves , determine if still on window/button (i'm still not 100% sure doing). and, when mouse button released, can call releasecapture() restore mouse messages sent. edit: oh, , can use windows api function windowfrompoint() determine window mouse over.

for listview, when register onitemclicklistener, method specify looks this: public abstract void onitemclick (adapterview parent, view view, int position, long id) the id corresponds row user clicked on. question why long , not int? when use long? i've been casting int when use it, makes me think maybe i'm using wrong. i think comes straight sqlite : in sqlite, every row of every table has 64-bit signed integer rowid. rowid each row unique among rows in same table. given that, seems natural android apis specify 64 bits id database row.

i implementing dynamic code execution in c# allows users write own c# particular application. i using c# code compiler executing dynamic codes. c# compiler reads code file , construct code in new namespace (a complete new code), compiles , runs it. in other view base application host these. i have few methods present in host application want executed dynamic code. there way method of other namespace or application can executed? could force author of script implement interface, or wrap code own implementation.. something like public interface imyapplication { void dosomethinginmymainapp(); } public interface iscriptkiddie { void init(imyapplication app); } then l33t scripters can write public class myscript : iscriptkiddie //< emit { public void init(imyapplication app) //<could emit if scripter knows app keyword { app.dosomethinginmymainapp(); } } and in app can provide concrete implementation of imyapplication pass

this question related this one . given wcf binding uses net.msmq:// url, instance net.msmq://server/private/nc_queue , how can 1 know actual msmq address url translated? there kind of trace can activated? or external tool 1 capture address? thanks. edit1 ok, owe clarification. 1 can talk directly msmq through respective .net api. in case of msmq on native port 1801, use msmq address: formatname:direct=os:server\private$\nc_queue when msmq configured on http, address changes this: formatname:direct=http://server/msmq/nc_queue but wcf binding uses standard url describe address, like: net.msmq://server/private/nc_queue so, how can know actual msmq address (the 1 formatname) net.msmq:// translated? i don't understand question.... if use wcf netmsmqbinding , you're dropping off msmq messages msmq queue. have queue name you're dealing - not url..... net.msmq://server/private/nc_queue this translates msmq private queue called nc_queue on se

i have built pyqt4 source , went smoothly until tried use of classes , attributes located in qtcore. reason qtcore missing lot of functionality , data should there. example pyqt4.qtcore import qt_version_str import error. there no errors or warnings given when building packages , have tried pyqt packages yum have same problem. has else encountered problem before? thanks. if it's importerror , suggests it's failing import library altogether. check it's somewhere that's in sys.path , , from pyqt4 import qtcore works. if library exists, , qt_version_str doesn't exist, give nameerror rather importerror .

i wish know there way can disable udp broadcast packet node not rcvd node itself. braodcast using inaddr_broadcast , on rcvr side using ai_passive | ai_numerichost. thanks arpit no, fundamental property of broadcasting - every host on subnet, including sender, have process packet way network stack. options are: switch multicast . preferred since multicast reduces load on whole network compared broadcast, , because can explicitly control multicast loopback ip_multicast_loop socket option. don't bind(2) destination port on sending machine. works sort of kludgy since puts restrictions on application design and/or deployment.

i'm newbie in ios dev. need windows tree views on it. created view-base application, , added uiview controls in master view. added 3 view controllers views view definition in separated xib files. how link views separated xib files view areas on master view? should manually create controller instances , load controller's view view areas? or maybe possible create them in ib? thank you. you should able drag instances of 3 controllers nib file of master view, , resize them in order create desired layout. however, make sure properties on subviews correct or overlap. in library window of ib, go classes tab, , drag classes want (view controllers) nib. i prefer method on manually adding them through code, allows better functionality resizing such rotation.

when use $this keyword in php? understand $this refers object created without knowing objects name. also keyword $this can used within method? an example great show when can use $this . a class may contain own constants, variables (called "properties"), , functions (called "methods"). <?php class simpleclass { // property declaration public $var = 'a default value'; // method declaration public function displayvar() { echo $this->var; } } ?> some examples of $this pseudo-variable: <?php class { function foo() { if (isset($this)) { echo '$this defined ('; echo get_class($this); echo ")\n"; } else { echo "\$this not defined.\n"; } } } class b { function bar() { // note: next line issue warning if e_strict enabled. a::foo(); } } $a = new a(); $a->foo();

it's common pattern blogs have archive pages (eg date or category) list relevant blog posts, along excerpts (a paragraph or) , link. can't quite work out of html5 elements it's best use individual posts, however. the <article> tag might seem fit (and if displaying whole content), i'm not sure whether it's appropriate excerpts. specification says: the article element represents self-contained composition in document, page, application, or site , is, in principle, independently distributable or reusable, e.g. in syndication. is excerpt self-contained , independently distributable piece of content? i'm not sure. other options might <blockquote> tag (but it'd weird quoting own posts), or <ol> list (ordered publication date) containing headers , paragraphs. any thoughts? i'd use: <li> <blockquote cite="original url"> </blockquote> </li> <blockquote> appropr

i have thread grabs data network or serial port. thread must terminate (or return false) if no data received within 5 seconds. in other words, if running thread taking more 5 seconds must stop. i writing in c#, .net language ok. there 2 approaches: 1. encapsulated timeout the thread reading data network or serial port can measure time elapsed time of start , wait data no more remaining time. network communication apis provide means specify timeout operation. hence doing simple datetime arithmetic can encapsulate timeout management within worker thread. 2. external timeout use thread (or in main thread if that's feasible) wait worker thread finish within time limit, , if not, abort it. this: // start worker thread ... // give no more 5 seconds execute if (!workerthread.join(new timespan(0, 0, 5))) { workerthread.abort(); } recommendation: i'd stick first solution, leads cleaner , maintainable design. however, in situation might necessar
