how can execute http requests or open socket on android wear? used think that's impossible web browser android wear app says folloing: "[..] works when phone off if have smartwatch android wear 5.1 , wifi"*. i tested , app can connect internet when paired phone powered off. whenever open socket or try http requests on android wear connectexception saying failed connect http://foo.com (similar stack trace here ). i'm doing different app doing , i'd understand is. context: i'm working on proof-of-concept , want able execute http requests , open sockets. i'd love know if there's way that. if includes rooting watch , doing adb magic. to clarify: know data layer api , i'd still able http requests , open sockets. if watch has wifi , set correctly, can make network calls on watch when watch disconnected phone; when connect phone via bt, wifi disabled. while enabled, should able treat usual network connectivity , make networ

my problem collision detection wrote enemy character objects , bullet objects. the symtoms: when 1 enemy character spawns , shoot bullets, enemy character destroyed normal. but, if 2 or more enemy characters spawn , shoot first enemy spawned nothing. last character spawned , shot destroyed without issue. how tried fix it: i decided give each enemy character unique id creating int variable , randomize each time enemy spawned. ensures me each enemy character object definately have unique identifier if shoot them, can somehow match unique id bullet. however, dont know how work around that. code below deletes every enemy character associated randomized tags my question: how can set bullet objects hold every unique id of enemy characters, when bullet hits 1 (doesn't matter specific order) search compare unique ids has enemy character id has shot? apologies if question unclear or if coding style horrible. gamescene.cpp /** * @param enemy_spawn_frequency value 0

i don't want elasticsearch taken offline while re-indexing (using scan , scoll api), strategy re-indexing online , in end check if number of documents in new index not less old index. note, did flush after re-index document counts correct. however, re-indexing, new documents added old index. in end of re-index, documents missing (which aren't missing, added after start of re-indexing). i don't dare alias new index official index name @ start of re-index. because, in case there documents missing, newly added documents during re-index in new index. want effect if new index fails, can delete without affecting old index. this won't problem if either diff 2 indices or if retrieve documents added after checkpoint time. i saw post @ diff indices in elasticsearch asks how diff 2 indices no answers that.

what code in c# winforms, can give me detailed explanation on how works? controls in statement. controls.add(btn); controls instance of control.controlcollection class, represents collection of control objects, inheritance hierarchy system.windows.forms.control.controlcollection note: the add, remove, , removeat methods enable add , remove individual controls collection. can use addrange or clear methods add or remove controls collection. you can determine if control member of collection passing control contains method. index value of location of control in collection, pass control indexof method. collection can copied array calling copyto method. example of removing control collection using 1 of it's method. // remove radiobutton control if exists. private void removebutton_click(object sender, system.eventargs e) { if(panel1.controls.contains(removebutton)) { panel1.controls.remove(removebutton); } } refer control.controlcollecti

i have django application. this django application makes api call twitter , gets 100 recent tweets. need insert tweets database. i have method act on 100 tweets. method has loop create model instance out of each tweet , call instance.save() on each instance separately. i found things slower , thought transactions might make things faster. so outside method added @method_decorator(transaction.atomic) . still have loop created model instance , instance.save() method decorated transaction.atomic. is transaction.atomic supposed make insertions database faster me? will each instance.save() call still issue database call? if makes things faster, how? in atomic transaction, series of database operations either all occur, or nothing occurs. decorating method atomic guarantee atomicity on database block of code within method. if method completed, changes committed database. if there exception, changes rolled back. 1. transactions not make code faster per use ca

from hardware point of view, force - release statements model? uses of force - release statement? the force/release statements used aid in simulations . one scenario avoid x-propagation in gate simulations. rtl code contains registers without asynchronous resets. although rtl simulations run cleanly, gate simulations not. either x's never resolved, or take many cycles resolve make simulations take impractical amount of time run. forcing , releasing random known value register during reset, simulation allowed proceed cleanly , complete in timely manner. another scenario involves large counters . example, see 32-bit counter roll over, requires 4 billion cycles. typically, want roll on several times in 1 simulation. again, take impractically long time simulate. force/release can used deposit random value counter close roll-over value. another scenario involves boosting code coverage results. can difficult achieve 100% coverage on metrics, when using ip ca
