Why doesn't the JVM cache JIT compiled code?
...d in the JVM implementation, but I can think of some plausible ones:
The idea of Java is to be a write-once-run-anywhere language, and putting precompiled stuff into the class file is kind of violating that (only "kind of" because of course the actual byte code would still be there)
It would incre...
How to get the difference between two arrays of objects in JavaScript
...
I take a slightly more general-purpose approach, although similar in ideas to the approaches of both @Cerbrus and @Kasper Moerch. I create a function that accepts a predicate to determine if two objects are equal (here we ignore the $$hashKey property, but it could be anything) and return a ...
How does Bluebird's util.toFastProperties function make an object's properties “fast”?
...htly outdated article is still a fairly good read that can give you a good idea on how objects are stored in v8.
Why it's faster
In JavaScript prototypes typically store functions shared among many instances and rarely change a lot dynamically. For this reason it is very desirable to have them in f...
How do you maintain development code and production code? [closed]
...tegrated (or scrapped) within a month or two.
Generally i don't like the idea of every developer working in his own branch, because you "skip go and move directly to integration hell". I would strongly advise against it. If you have a common codebase, you should all work in it together. This makes...
Why does the use of 'new' cause memory leaks?
...be a memory leak.
The following code is just to make a point, it's a bad idea, don't ever like code like this:
class B
{
public:
B() {}; //default constructor
B(const B& other) //copy constructor, this will be called
//on the line B object2 = *(new B())

How does password salt help against a rainbow table attack?
...
The idea with the salt is to make it much harder to guess with brute-force than a normal character-based password. Rainbow tables are often built with a special character set in mind, and don't always include all possible combina...
What are enums and why are they useful?
...h, but it's so tricky that it even more clearly shows why enum is a better idea.)
Thread safety
Thread safety is a potential problem only when singletons are created lazily with no locking.
public class SingletonClass {
private static SingletonClass INSTANCE;
private SingletonClass() {}

Error “initializer element is not constant” when trying to initialize variable with const
...ted on GCC's web site as a C language extension. In other words, I have no idea how and why it compiles in ideone. Even if it compiles as a language extension, it should still produce a diagnostic message in C.
