java - android 4 onCreateDialog return type incompatible when overriding -

the code below won't compile. understand when doing override, replacement class must match signature of original class exactly, think i'm following example android documentation carefully. error messages: overrides android.app.activity.oncreatedialog return type incompatible activity.oncreatedialog(int) oncreatedialog() method: @override protected dialog oncreatedialog(int id) { switch (id) { case 0: alertdialog.builder builder = new alertdialog.builder(this); builder.seticon(r.drawable.ic_launcher) .settitle("this dialog stupid message...") //more code here setting additional properties ); return builder.create(); } } you need default return block in switch or return after switch. can return null in cases.

python - Grouping of all possible combinations of points taken m at a time into r groups -

i want group possible combinations of points taken m @ time r groups. points = [a,b,c,d........] total n points combinations of these points taken m @ time list l l = list(itertools.combinations(points,m)) how can further group r groups such i-th element of each group has no similar points. for example, points = [a,b,c,d] m = 2 , r = 2 l = [[a,b],[a,c],[a,d],[b,c],[b,d],[c,d]] so groups be group 1 = [[a,b],[a,c],[a,d]] , corresponding group 2 = [[c,d],[b,d],[b,c]] note : points in i-th index of group 1 , group 2 have no similar points. i want n number of points taken m @ time , grouping r groups. please provide me algorithm. also note when number of points increases, possible combinations increase if want more 2 groups. this tough problem! i've implemented naive brute force solution. slow it's starting point. from itertools import combinations, permutations points = 'abcdef' r = 3 m = len(points) // r

according gmail's api docs , limits follows: api limit type limit daily usage 1,000,000,000 quota units per day per user rate limit 250 quota units per user per second, moving average (allows short bursts) in table further below, docs messages.get costs 5 quota units. in case, interesting in polling inbox every second check new messages, , contents of messages if there any. question 1 : mean i'd spending 5 quota units each second, , i'd under quota? question 2 : how should check "new" messages? is, messages have arrived since last time made api call? need add "read" labels messages after each api call (spending quota units on "modify" api call), or there easier way? question 1: that's right. spend (5 * 60 * 60 * 24 =) 432000 quota points on polling, near limit. implement push notifications if want google notify of new messages rather polling yourself. question 2: listing messages has undocumented feature

perl - Can Test::Class tests be run in parallel? (or how to factor out superclass tests) -

in tutorials i've read test::class , there seems 1 runner script loads of classes. , think perspective of test::harness 1 giant test. don't think can parallelize tests inside runner. my x problem trying factor out superclass behaviors when testing subclasses. each subclass should have own subclass test (that can parallelized), exercise behaviors inherited superclass. how 1 that? edit: found these 2 posts 2007 seem imply i'm asking incompatible/not possible. update since then? http://www.hexten.net/pipermail/tapx-dev/2007-october/001756.html (speculation test::class support parallelism http://perlbuzz.com/2007/08/organizing-tests-with-testclass.html (implying test::class , test::harness ideologically exclusive) test::class doesn't support parallelisation on own. easiest solution have separate .t runners each of test classes (or logical groups of test classes), , run using e.g. prove -j9 . if want run of tests in parallel write simple scri

ios - Architecture of a SceneKit game, multiple view controllers for menu screens? -

-
i'm working on scenekit game using swift, , i'm thinking best way organize various screens/ states surrounding actual main game scene. have simple prototype consists of 3 states: splash screen (choose game type) -> game -> game on screen (choose play again or return splash) in prototype opted go uikit ui elements, rather spritekit overlay. although it's buttons @ moment, easy enough in spritekit, might in future want add sliders (eg options screen set control sensitivity etc), text entry etc, , end recreating great chunks of uikit. so @ present, each of 3 scenes described above has own uiviewcontroller . splash , game viewcontrollers have own scnview s , scnscene s, , gameover modal displays on main game scene. this structure isn't ideal, means main game scnscene gets reloaded whenever viewdidload of gameviewcontroller fires. main scnscene quite detailed takes few seconds load, , repeated cycles seems create memory issues. after 2 cycles of spla
