问题 I've found in Akka docs: When using future callbacks, such as onComplete, onSuccess, and onFailure, inside actors you need to carefully avoid closing over the containing actor’s reference, i.e. do not call methods or access mutable state on the enclosing actor from within the callback. So does it mean that i should always use future pipeTo self and then call some functions? Or i can still use callbacks with method, then how should i avoid concurrency bugs? 回答1: It means this: class

问题 As you can see at this Fiddle, I animate more than one element at once, which is happening as I wish. But in the next step, I would like to do things ONCE the animation for all elements is over. Which does not seem to be possible by using the complete-function, because it is it fired for EACH completed animation (3 elemets, 3 times complete callback). the jquery .animate() API also says: If multiple elements are animated, the callback is executed once per matched element, not once for the

问题 I've got a Python program which sits on a remote server which uploads a file to an AWS bucket when run. If I ssh onto the server and run it with the command sudo python3 /path/to/backup.py it works as expected. I'm writing a Python program to automate a bigger process which includes running backup.py. I created a function to do this using the paramiko library. This is where the command gets run ssh_stdin, ssh_stdout, ssh_stderr = self.ssh.exec_command('sudo python3 /path/to/backup.py', 1800)

问题 I have base class Foo with method spam and class Bar which overrides spam . I need to call spam of base class in method of some callback object which is defined in-place: public class Foo { public void spam() { // ... } } public class Bar extends Foo { @Override public void spam() { objectWhichRequireCallback(new Callback { @Override public void onCallback() { super.spam(); } }); } } This code is not working because super is related to Callback , not Bar class. Is it possible to call super

问题 I have this simple function in jQuery: function detailspage(page) { if (page != checkcurrent) { checkcurrent = page; $('div#details').children("div").slideUp("slow", function() { $('div#details').children("div"+page).slideDown("slow"); }); }; }; I have put three <div> 's inside another <div> called <div id="details"> , and they are all slided up and out of sight by default. I now wish to make each of them slide down, when a button for each of them is clicked. Of course a <div> that is open
