i have downloaded several example android games, , of them not use android's animation methods. have seen several posts on site , other sites prefer not use android's animation methods, never explain why . so, better not use android's animations games? i not recommend using android's animation classes games. reason operate on views not lightweight enough high performance games require. views designed buttons, text, , images stay still, positioned in organized layouts , , not images move on place. 2 best approaches making games android are: using canvas class. note work simple 2-d sprite-based games, tends quite slow. it's relatively easy beginners learn. using opengl es . works pretty game - it's fast , can both 2-d , 3-d games. be warned, complicated , not recommend beginners use opengl es! if new programming games, recommend buying book on topic such mario zechner's excellent book "beginning android games" (look on amazon)

i'm using window.history in javascriptmvc application enable back/forward/refresh functionality each controller. every time load new controller i'm using window.history.pushstate add new state history. , on back/refresh i'm using saved state , reuse data build controller again. the whole idea works fine excepting 1 issue on specific scenario. i'm getting following error: failed execute 'pushstate' on 'history': object not cloned. the same data added without problem on other scenario. can cause error? assistance. https://developer.mozilla.org/en-us/docs/web/guide/api/dom/manipulating_the_browser_history "the state object can can serialized. because firefox saves state objects user's disk can restored after user restarts browser, impose size limit of 640k characters on serialized representation of state object. if pass state object serialized representation larger pushstate(), method throw exception. if need more space

i have these 2 classes - letadlo , letiste (plane , (home)airport). while saving data db, using java , hibernate , i'm getting exception: 16285 [thread-2] error org.hibernate.property.basicpropertyaccessor - illegalargumentexception in class: mapy.letiste, getter method of property: id org.hibernate.propertyaccessexception: illegalargumentexception occurred calling getter of mapy.letiste.id @ org.hibernate.property.basicpropertyaccessor$basicgetter.get(basicpropertyaccessor.java:198) @ org.hibernate.tuple.entity.abstractentitytuplizer.getidentifier(abstractentitytuplizer.java:227) @ org.hibernate.persister.entity.abstractentitypersister.getidentifier(abstractentitypersister.java:3876) @ org.hibernate.persister.entity.abstractentitypersister.istransient(abstractentitypersister.java:3584) @ org.hibernate.engine.foreignkeys.istransient(foreignkeys.java:203) @ org.hibernate.engine.foreignkeys$nullifier.isnullifiable(foreignkeys.java:159) @ org.hibe

i have data in xyz type. example: x = numpy.arange(100) y = numpy.arange(100) z = numpy.random.random_sample((100,)) i bin data, example, overlap lengths of dx = 2 , dy = 2 . did is: nx = len(x) ny = len(y) bin_data = np.zeros((nx, ny)) in range(nx): j in range(ny): a, b, c in zip(x,y,z): if (x[i] < a) , (a < x[i] + dx): if (y[j] < b) , (b < y[j] + dy): bin_data[i,j] += c for these small data program runs well. takes me time if data big. can please recommend faster algorithm bin data overlapping in python. know numpy.histogram2d quite fast, not work overlapping binning. i thing make algorythm faster moving zip outside of 2 other loops, imho longest operation : for a, b, c in zip(x,y,z): in range(nx): j in range(ny): ... then, in exemple, make use of x[i] == , y[j] == j (i add +1 because have strict < ) : for a, b, c in zip(x,y,z): in range(a - dx + 1, a):

i have system takes excel file, manipulation , exports csv file ready import else. everything works except numbers; when csv file import final system numbers show 1e+11 example. i have previous csv file works , difference can see when open in notepad there whitespace after number e.g 123456643567 ,872871643567 ,465435654356 whereas new file doesn't have whitespace after number e.g 123456643567,872871643567,465435654356 this difference can see can presume causing problem, don't know how add white space in. if try , append whitespace end numbers surrounded speech marks , still doesn't work e.g "123456643567 ","872871643567 ","465435654356 " is there way add in or there else @ work causing issue? edit: for reference, below code have read in excel file using phpexcel: // identify type of $file $file_type = phpexcel_iofactory::identify($file); // create new reader of type has been identified $reader = phpexcel_iofactory::c

i hope use role based access control function managing user on xenserver. i have server(xenserver 6.2) , ad server(windows 2008 r2). ad server installed windows 2008 r2, ad , dns. then, clicked join domain button on xencenter users tab. and, input domain, user name, password. domain qualified domain name ( e.g. aaa.bbbbbb.com) username 'administrator' (default user). but, can't success. show error. 'xenserver unable contact domain server enable external authentication. check settings correct , route server exists.' how can use rbac function? the 3 important things check: the clock of xenserver , ad server synchronised. use same ntp server both of them. xenserver , ad server both using same dns server. all necessary ports (53, 88, 123, 137, 139, 389, 445, 464, 3268) not blocked firewall also, see xenserver admin guide, in section configuring active directory authentication: http://support.citrix.com/servlet/kbservlet/download/383

my question can seems weird, realize when receive push new mail gmail app , open gmail on web page, notification disappear. can explain me how working ? this related this question , though it's not exact duplicate. this can implemented apple push notifications. your server has maintain each user list of device tokens of devices belonging user (iphones, ipads, etc...). when user reads message on 1 platform (whether via web browser or via mobile application), can execute api call on server notify user read message. then server can send follow-up push notification devices belonging user "badge"=0 (and without "alert" , "sound" fields), , notification cleared lock screen , app icon.
