i made class uibutton , override awakefromnib. next (green button) use class. i have space in right of next button (green one). space more in ipad: override func awakefromnib() { super.awakefromnib() let path = uibezierpath(roundedrect: self.bounds, byroundingcorners: [.topleft, .bottomleft], cornerradii: cgsizemake(5, 5)) let masklayer = cashapelayer() masklayer.path = path.cgpath self.layer.mask = masklayer self.layer.bordercolor = mycolor.nextbuttonborder.cgcolor } you should put code in layoutsubviews() method. don't forget delete previous added masklayer. full example: override func layoutsubviews() { super.layoutsubviews() self.layer.mask = nil let path = uibezierpath(roundedrect: self.bounds, byroundingcorners: [.topleft, .bottomleft], cornerradii: cgsizemake(5, 5)) let masklayer = cashapelayer() masklayer.path = path.cgpath self.layer.mask = masklayer self.layer.bordercolor = mycolor.nextbut

in rails, can use adapter of sqlite3 access sqlite3 database. want use datastore database. there google datastore adapter sqlite3's ? development: adapter: sqlite3 database: db/development.sqlite3 has been tried? yes. idea? probably not. activerecord object relational manager built around relational sql databases. sqlite adapter adapter lets activerecord talk sqlite. while can swap mysql, postgresql or oracle adapter going on no-sql land not smooth sailing. there reason separate rails orms mongoid mongodb exist. concepts in non-relational database different , not should abstracted away adapter.

i'm new in c# , write class: public class manager { public string versionname { get; set; } public double value { get; set; } } , use this: list<manager> lstsummary = new list<manager>(); manager summary = new manager(); summary.versionname = "12"; summary.value =12; lstsummary.add(summary); summary.versionname = "13"; summary.value = 19; lstsummary.add(summary); code save latest class record ,means save versionname=13 , value=19 ,how can solve problem?thanks. you have re-instantiate summary variable so: manager summary = new manager(); summary.versionname = "12"; summary.value =12; lstsummary.add(summary); summary = new manager(); // <-- add summary.versionname = "13"; summary.value = 19; lstsummary.add(summary);

i need scale aurora db , down @ later sometime dont need downtime not bit. though of doing creating aurora replica , promoting scaling primary , promoting primary. involve downtime. please suggest alternative way. i first ask in sense need scale up? writing? reading? if run server high-read/low-write ratio, i'd suggest read-replica (or more) , configure application use read replica in specific cases you're making queries , not modifying data. in sense, you're offloading writes separate instance of same data , letting primary deal writes. if did this, i'd suggest spreading out read replicas across other availability zones, in case az of primary goes down, read-replica auto-promoted primary. armed info, suggest scale read replicas application configured use, can bring down replicas scale down without ever bringing down aurora primary. it's more of configuration problem in dealing multiple rds endpoints, essentially. hth. one caveat there delay in r

i wanted clarify if understand correctly: == -> reference comparison, i.e. both objects point same memory location .equals() -> evaluates comparison of values in objects am correct in understanding ? in general, answer question "yes", but... equals compare written compare, no more, no less. if class not override equals method, defaults equals(object o) method of closest parent class has overridden method. if no parent classes have provided override, defaults method ultimate parent class, object, , you're left object#equals(object o) method. per object api same == ; is, returns true if , if both variables refer same object, if references 1 , same. testing object equality , not functional equality . always remember override hashcode if override equals not "break contract". per api, result returned hashcode() method 2 objects must same if equals methods shows equivalent. converse not true.

(solution on bottom of post). currently we've problem in our project using ng-animate . we've got 2 states, lets name them now: state 1 , state 2. both have state name div class. <div class="state1"> . now state1 should slide top, , slide2 should slide in bottom. working fine when switching between slide1 , slide2. however, if user clicks on button moves state1 (when being on state1) content should change , no animation should done. currently use: .state1.ng-leave { } leaving animation on state1 div, , .state2.ng-enter { } on entering state. can see, when i'm on state1 , clicking on button give page state1 still .state1.ng-leave { } called , animation done. anyone got solution us? ng-leave {} state1 should triggered state2 entering. state1/state2 flow things we've tried: we tried add state('home.state1', { } block ng-animation state1. when enter state1, never need animation. didn't find solution using this. there can

many people use bouncy castle use wonderful implementations of java cryptography api (jca) ciphers, messagedigests, etc. many use circumvent export control restrictions imposes on usage of cryptography key lengths exceeding 128 bits. however, have read somewhere in 2016, there changes in restrictions govt imposes. can stop using bouncy castle , switch native java jca provider if reason why used in project? can throw light on ? yes. it's called java 9. try it. can disable export control programmatically . besides that, bouncy castle provider does not circumvent export control, lightweight api does. because cipher class contains constraint, , service provider implementations (spi's) used through class.

i decided add dependencies pom.xml file using 'select dependency' functionality. when added selenium-java dependency, observed version added 2.42.2 instead of latest version of 3.0.1. double-checked central repository make sure 3.0.1 available, is. although can manually edited, why old version being called pom? see image attached. the usual reason indices not correct. there various possible reasons that: in eclipse, "download remote indices" not activated. the indices not downloaded correctly, check in "maven repositories" view. the index of (company) nexus broken , has updated/repaired. all in all, find indices out of date.

i'm working in bit of weird situation need create api connects different database based on supplied parameters in request. write api in sails.js because i've worked bit (as opposed other frameworks). my problem cannot make dynamic connection in it, connections loaded upon lifting. i've found few related answers. first 1 https://stackoverflow.com/a/34845674/7131845 , says use custom service handle connection dynamically , suggests use of models it. , second 1 one: https://stackoverflow.com/a/38458390/7131845 pretty that. i did myself: i've created service handles connection database provided parameters, issue don't know how connect model work service instead of connection/adapter set. appreciate help.
