hopefully can advice on this. my program has sprite that, when hit/clicked, score tallied on screen. when game on (time runs out), want user able press key on phone go main/start screen/activity began game, show score (how many hits). i'm struggling figure out how go back key press. can figure out high score bit @ later date if need be. want start screen. update: i think may have manifest why it's not working. i've tried add 'gameview' class manifest won't accept it. says has no default constructor. ideas? <application android:allowbackup="true" android:icon="@drawable/ic_launcher" android:label="@string/app_name" android:theme="@style/apptheme" > <activity android:name="cct.mad.lab.mainmenu" android:label="@string/app_name" > <intent-filter> <action android:name="android.intent.action.main" />

here's have: sql table/csv file "tile xyz" coordinates (web mercator tile coordinates) , "data/color" x y z color 13 13 5 yellow 13 14 5 green 13 14 5 red ... data structure easy, no fancy stuff needed, can draw pngs code. amount of data large, i.e. worldwide tiled, zoomlevel 15 what want: png tiles underlying data should not accessible show png tiles webpage map of leaflet/google maps api problem/question: too data generate tiles worldwide before (takes days) i therefore thinking dynamic caching/tile creation algorithm (maybe create zoomlevel 0-9 before, higher zoom levels created dynamically) it seems there many tools out there (tilemill, tilestache, arcgis server, etc) of them seem have high learning curve or meant more complex tasks. is there way run lean server fits needs? maybe php script queries database, draws png , feeds map on-demand? how work exactly? clever solution? thanks much. i

i running structured streaming (2.1.0) on 3-node yarn cluster , stream json records parquet. code fragment looks this: val query = ds.writestream .format("parquet") .option("checkpointlocation", "/data/kafka_streaming.checkpoint") .start("/data/kafka_streaming.parquet") i notice creates thousands of small files 1,000 records. suspect has frequency of trigger. changed it: val query = ds.writestream .format("parquet") .option("checkpointlocation", "/data/kafka_streaming.checkpoint") .**trigger(processingtime("60 seconds"))** .start("/data/kafka_streaming.parquet") the difference obvious. can see smaller number of files created same number of records. my question: there way have low latency trigger , keep smaller number of larger output files?

this question has answer here: when did `guard let foo = foo` become legal? 1 answer why isn't guard let foo = foo valid? 1 answer i'm reading erica sadun's swift style book , playing around code. she suggests: prefer using same-name shadowing in conditional bind. “this approach both conventional , safe: guard​ ​let​ x = x { ... } ​// yes​ guard​ ​let​ y = x { ... } ​// no​ deliberate same-name shadowing ensures the unwrapped value’s role follows logical intent established name prior if or guard statement. introducing new name blurs line of semantics , can prove dangerous. consistent same-named shadowing prevents adding unintentional shadow symbols in parent scope. regardless of being opinion or not: in code, i'm trying do: guard

i adding cocoa pods ios project (swift). have initalized pods in project directory using 'pod init myproject.xcodeproj'. added pod 'firebase' podfile such: project 'hots ios.xcodeproj/' platform : ios, '9.0' target 'hots ios' use_frameworks! pod 'firebase' target 'hots iostests' inherit! :search_paths pod 'firebase' end target 'hots iosuitests' inherit! :search_paths pod 'firebase' end end now when run pod install error: unable find specification 'firebase'. depending on firebase service want use have add different firebase services in podfile. "'firebase'" not valid pod. pod 'firebase/core' basic , give prerequisite libraries needed firebase running. if want use other services can choose between these pods: pod 'firebase/core' --> prerequisite libraries , analytics pod 'firebase/admob' -->

my issue similar : spring jms - ibm mq has open input count issue i have set message driven bean have max-sessions 1 sequential message delivery in websphere. assume 1 connection should open queue. see open input count 2 times. times 2 different process in picture, same. normal behavior of websphere? please advise. investigating messsage re-ordering issue, of great help. websphere version 8.5.1 , ibm mq version 7.0 mdb configured via activation spec the 2 instances queue opened different 1 has queue opened browsing , other has open destructive gets. don't see how having opened twice these affect ordering of messages. mq doesn't guarantee ordering of messages default. if message ordering important should use message groups, explicitly define ordering of messages in mqmd of each message. without message groups need meet number of requirements assume message ordering kept mq.

while(result.length() != alltext){ b = (boolean)(i < variable); for(i = firstr; b; i++){ //do } b = (i < variable); } am can change condition boolean? in code b = condition converted true or false . want keep condition . this: b = (boolean)(i < variable); does not mean value of b "binds" condition i < variable . i.e. not mean when i changed value larger variable , b 's value change. b assigned once. you either put i < variable in loop condition, or can use lambda (predicate): // assuming int intpredicate b = x -> x < variable; // change loop for(i = firstr; b.test(i) ; i++){ if don't know lambdas are, represent anonymous classes. lambda expression in above code represents anonymous class: new intpredicate() { public boolean test(int x) { return x < variable; } } imo, should not use predicate. write condition should be. way easier understand loop in form: for (i = x ; < y

what want is, when new comes database, gets latest value entered , plays specific song depending on says. for example, on computer, run website. else around world picked phone , clicked play song, song automatically play on devices running page. when chooses new song, song should change. i have made several tries @ this, trying use setinterval in javascript updates , updates time expect. i guess looking way track when database has been updated, solutions or code examples can use? if understand right, can use push notifications. https://firebase.google.com/docs/notifications/ here's tutorial how set js client https://firebase.google.com/docs/cloud-messaging/js/client in case won't have unnecessary requests server fetch updated. send push notification client , necessary actions on client side.
