i've implemented small box on website @ bottom of page expand when mouse hovers on it... code , works great. css #box{ position:absolute; width:300px; height:20px; left: 33%; right: 33%; min-width: 32%; bottom:0; background-color: #353535; } javascript $('#box').hover(function() { $(this).animate({ height: '220px' }, 150); },function() { $(this).animate({ height: '20px' }, 500); }); but i'm curious how go changing open , close on click rather mouse hovering on it? i've edited to... $('#box').click(function() { $(this).animate({ height: '220px' }, 150); },function() { $(this).animate({ height: '20px' }, 500); }); and works open box. can't close again click. so close yet far! :p this should work $('#box').toggle(function() { $(this).animate({ height: '220px' }, 150);

i wonder why doesn't work? var attr = $("a").attr('rel'); if (typeof attr == 'lightbox') { $(this).addclass("lightbox"); } i want add class link has rel attribute set "lightbox". this should work... right? $('a[rel="lightbox"]').addclass("lightbox"); that should trick. typeof - returns data type not value! trying compare type (string) value (lightbox).

one of central tenets of architecture of latest app i'm going call methods on app's model async , accept failure , success scenario blocks. i.e., ui calls model method 2 blocks, 1 success , 1 failure. this great because context of original call retained, however, block called on background thread. there anyway of calling block on main thread?? hopefully have explianed ok, if not, basically, model methods async, return , create new thread on run op. once op returns invoke block postprocess returned data, need call block success scenario defined called inside ui. however, success , failure scenario blocks defined in ui should called in main thread because need interact ui elements should done on main thread believe. many something you're after: - (void) dosomethingwhichtakesageswitharg: (id) thearg resulthandler: (void (^)(bool, id, nserror *)) handler { // run in background, on default priority queue dispatch_asyn

recently discussed defect mentioned here , 1 of parties said "yes, that's why books inheritance should avoided . i've been using inheritance years , find useful , convenient in many design cases. i'm sure person arguing @ least misunderstood "books say". is there idea inheritance kind of bad , should avoided? originate , can learn more? i think might have meant inheritance can overused, in cases composition better solution. discussed in several books, e.g. effective java 2nd edition , item 16: favor composition on inheritance inheritance powerful way achieve code reuse, not best tool job. used inappropriately, leads fragile software. safe use inheritance within package, subclass , superclass implementations under control of same programmers. safe use inheritance when extending classes designed , documented extension (item 17). inheriting ordinary concrete classes across package boundaries, however, dangerous. reminder, b

i'm implementing graph (as in vertices, edges, not cartesian). i'm modelling graph physical collection of nodes (a class i've made). i want have collection of forces, vectors (in maths sense), represent forces acting upon each node, , ideally able perform lookup node key, sounds me kind of hash lookup table. what's collection use, or have make own? if needs clarifying, ask. thanks if have understood needs correctly, want one-to-many mapping of node->vector. provided node implements hashcode() , equals(), use multimap google guava. provides map<node,collection<vector>> mapping automatically. the benefit of using multimap don't need this: collection<vector> vectors = nodetovectormapping.get(node); if (vectors == null) { vectors = new hashset<vector>(); nodetovectormapping.put(node, vectors); } vectors.add(vector); instead, need this: nodetovectormapping.put(node,vector); the multimap takes care of c

i have log statement in use this.getclass().getsimplename() as 1st parameter. put in sort of macro constant , use in log statements. learned java has no such simple mechanism unlike c++. what best way achieve sort of functionality in java? my example log statements (from android) follows.. log.v(this.getclass().getsimplename(),"starting lociden service..."); java doesn't have macros can make code shorter: log.v(this, "starting lociden service..."); and in log class: public void v(object object, string s) { _v(object.getclass().getsimplename(), s); } another approach inspect call stack.

here's looking do: a person goes site , quicktime movie plays. at end of movie, new image appears (ideally fades in). i guess there 3 ways can happen: a. quicktime image window replaced image. b. quicktime image window moves background/behind existing image on page (or background image comes forward on top of quicktime image window). c. after completion of quicktime movie, site automatically redirects new page. i have components page, have not been able locate code out there can make happen. thanks in advance :) you don't have access plugin that's playing mov. you'd have use native html 5 video. in case: if it's same video - , same length - try running javascript timer in background. when time's up, 1 of things mentioned. html 5 video brings along new media events can use. in case ended event seems appropriate. you'd bind video element other event. on it's simple dom scripting, like: function myhandler(e) { if(!e) {

i'm writing little spider in python. hits page, gets links on page according pattern, goes each of pages, , repeats. i need make recursive somehow. below url patterns: www.example.com then links based on regex, visit each page. recursive part: say visiting page url like: www.example.com/category/1 now if page contains links like: www.example.com/category/1_234 (basically same url, except has additional "_234234") i visit page, check url like: www.example.com/category/1_234_4232 (again, same url plus underscore , number) i keep doing until there no more links fitting pattern. 1. visit category page 2. contain links same url + "_dddd" if yes, visit page 3. #2 unless no links i don't need regex, need structuring recursive call. just-recursion, in manner asking for, might not best approach. for 1 thing, if there more 1000 pages indexed, might 'bottom out' call stack , crash. another, if not careful releasing

is there way java.lang.system used in dependency injection? currently build classes public class myclass { private final dependency idependency; public myclass(dependency pdependency) { this.idependency = pdependeny; } public static myclass createinstance() { final dependency tdependency = dependency.createinstance(); final myclass tinstance = new myclass(tdependency); return tinstance; } // ... class methods ... } and create using: myclass tmyclass = myclass.createinstance(); and test use: @test public void testmethod() { // setup dependency ttestdependency = new testdependency(); myclass tmyclass = new myclass(ttestdependency); // test tmyclass.method(); } now have problem have java.lang.system dependency want write console logger. have no problem setting system datatyp dependency eclipse says no when want set system parameter. error "system cannot resolved variable".

i have several tables joining need add table , can't seem right query. here have - table 1 carid, catid, makeid, modelid, caryear table 2 makeid, makename table 3 modelid, modelname table 4 catid, catname the query using join these is: select * table1 join table2 b on a.makeid=b.makeid join table3 c on a.modelid=c.modelid join table4 d on a.catid=d.catid a.carid = $carid; now need add 5th table getting 3rd party having hard time adding existing query. new table has these fields - table 5 id, year, make, model, citympg, hwympg i need citympg , hwympg based on caryear table 1, makename table 2, , modelname table 3. know can second query values, prefer single query , have of data in single row. can done in single query? if so, how? it's possible have more condition in join. work? select a.*, e.citympg, e.hwympg table1 join table2 b on a.makeid=b.makeid join table3 c on a.modelid=c.modelid join table4 d on a.catid=d.catid join ta

i have develop application have continuously collect gps, accelerometer data [esp. when user in motion i.e traveling, else can relaxed). have communicate web server , handle response sever. this(handling response ) part application should continuously poll. based on response server have show ui user. i not clear design. do have create activity start service. should service ran separate thread(this runs in background). i planning create 2 services. 1 service continuously collect gps data. other service communicating web server[start timer/alarm manager] polling. can these 2 services communicate each other. also after processing response frm server service should able start user interface show form. not clear how handle this. also acquiring wakelock required if have collect gps data continuously. please clarify. thanks you can use alarmmanager polling. need set interval. notice components application, service, activity contexts. can application context.

i have scenario hibernate second-level-cache enabled , i'd cache entity 1000 instances created every day , retained 8 years queries deal recent 2 days. avoid having create history table because rare cases historical lookup, code dependent on date. is possible in hibernate, infinispan level-2 provider, configure specifically, particular cache specific attributes (eviction policy, size, etc.) hibernate should use entity foo? yes. in hibernate, can have n cache "regions", can have different configurations , can specific entities. configuration dependent on provider (infinispan, in case). see document more details on infinispan configuration: http://community.jboss.org/wiki/usinginfinispanasjpahibernatesecondlevelcacheprovider#advanced_configuration look @ examples on how override defaults entity/collection. there, can set eviction strategy, lifespan , number of entities keep in cache.

what i'd scan set of java classes, , trace method calls specific method of abstract class, , within context, build list of code performs operation (in case, instantiates instance of class). want know, line number, , arguments supplied. i've begun looking @ bcel, doesn't seem have call graph tracing built in? i'm hesitant write own because getting overloading, type signatures , polymorphic dispatch right might be tricky. i half expected tool or example code exist, haven't found yet. feels i'm reinvent wheel. if open source wheel , available on github ;-) ps: find existing question " how generator java call graph ", because sounds identical, it's not @ need. you can use java-callgraph tool suite create accurate enough static , dynamic callgraphs java.

ipsec employed @ ip level, ssl @ transport level , pgp @ application level. in lecture not says: ipsec: general solution least flexible ssl: still general , flexibility pgp: least general flexibel. i guess general refers kind of protocol can secure. ipsec can secure uses tcp or udp. pgp least general because encrypts emails , therefore specific. understanding right? however have no idea flexibilty refers in context, idea? has extensibility? thanks ipsec: internet layer protocol, means runs above ip layer, such tcp or udp example, or other newer protocol, encrypted ipsec. however, protocol encryption/authentication of packets/protocol above , this, less flexible in some sense compared other 2 still flexible if need network encryption. ssl: encryption protocol, similar (i guess) ipsec, operates @ higher layer ipsec. operates on application layer means protocol runs on top of tcp, udp, etc... now 1 problem ipsec flexible in respect in lower in network layer, p

is there way close browser window, guaranteed ? last time heard, calling window.close() or self.close() works when current window launched window. there way majority of browsers close current window when isn't so? there no way close parent window via script without prompting in major browser. so nope, no guarantees. on child window, window.close , self.close both work great.
