i have researched on net benefits of immutablejs on object.freeze() didn't find satisfying! my question why should use library , work non native data structures when can freeze plain old javascript object? i don't think understood immutablejs offers. it's not library turns objects immutable, it's library around working immutable values. without repeating docs , mission statement , i'll state 2 things provides: types. implemented (immutable) infinite ranges, stacks, ordered sets, lists, ... all of types implemented persistent data structures . i lied, here's quote of mission statement: immutable data cannot changed once created, leading simpler application development, no defensive copying, , enabling advanced memoization , change detection techniques simple logic. persistent data presents mutative api not update data in-place, instead yields new updated data. i urge read articles , videos link , more persistent data structures (...

to clear, trying find out how collections.sort(list, new mycomp()) method calls compare method in sequence. i have linkedlist employees , personal number (k): numbers are: {1,2,3,4,5,6} compare(object o1, object o2) method in mycomparator gives number (which not relevant concern). how sort() call method compare? call parameters 1,2 then, 2,3 3,4 4,5 5,6? debug there's strange sequence jumps , compares 1,3. what compare? pattern? the specific comparisons made depend on algorithm, internally, collections.sort method using sort elements. according javadoc collections.sort : the documentation polymorphic algorithms contained in class includes brief description of implementation. such descriptions should regarded implementation notes, rather parts of specification. implementors should feel free substitute other algorithms, long specification adhered to. (for example, algorithm used sort not have mergesort, have stable.) in other words, java implementations free...

this tutorial java docs deadlock. don't threads blocked. since synchronized thought 1 thread 'll enter bow. both entered bow. [one waits [but when?]] then issue? when add comments [print statements trace]. there's no deadlock. how? public class deadlock { static class friend { private final string name; public friend(string name) { this.name = name; } public string getname() { return this.name; } public synchronized void bow(friend bower) { system.out.format("%s: %s" + " has bowed me!%n", this.name, bower.getname()); bower.bowback(this); } public synchronized void bowback(friend bower) { system.out.format("%s: %s" + " has bowed me!%n", this.name, bower.getname()); } } public static void main(string[] args) { final friend alphonse ...

some time ago created script using python, script execute actions in instance based on configuration file. this issue, created 2 configuration files. config.py instance= <production url> value1= value2= b ... testconfig.py instance= <development url> value1= c value2= d ... so when want script execute tasks in development instance tests, import testconfig.py instead of config.py. main.py # config import * testconfig import * the problem comes when update script using git. if want run script in development have modify file manually, means have uncommited changes in server. doing change takes 1 min of time feel i'm doing wrong. do know if there's standard or right way accomplish kind of tasks? export environment variables on machines, , chose settings based on environment variable.
