I'm working on a project where a spinlock is more appropriate than a mutex, and after few tries I came up with:
type SpinLock uint32
func (sl *SpinLock) Lock() {
for !atomic.CompareAndSwapUint32((*uint32)(sl), 0, 1) {
runtime.Gosched() //without this it locks up on GOMAXPROCS > 1

I'm trying to figure out how to declare a static variable scoped only locally to a function in Swift.
In C, this might look something like this:
int foo() {
static int timesCalled = 0;
++timesCalled;
return timesCalled;
}
In Objective-C, it's basically the same:
- (NSInteger)foo ...

Given the binary Tree and the two nodes say ‘a’ and ‘b’, determine whether the two nodes are cousins of each other or not.
Two nodes are cousins of each other if they are at same level and have different parents.

I decided to strengthen my "vanilla javascript" skills since I've lately been getting more into jquery and just discovered the potential of node.js.
So as a result, I decided to make a basic alarm clock in javascript and html. (Plus I needed an alarm clock ).

My code:
import os
all_files = os.listdir(".")

I've previously stated that I believe that requests to review just interfaces are off-topic. I'd like to add a second answer explaining why I think they should be off-topic.
A key ingredient to the success of Code Review is our working-code requirement. It brings concrete benefits to the commun...
Let's look at our six magic questions.

Applying ckuhn203's answer, but I disagree with the last point; it doesn't actually do anything, so it's not working code for me.
It's more like a bunch of structs.
And what can you ask about a bunch of structs and interfaces?
Well, whether you've named them right, of course... bu...
I'm currently developping an MVC framework on which I will be writing my websites. This is done through the usage of a starter kit.
In standard MVC, your routes are registered like the following:

Here is how you can use JUnit 4's Parameterized runner with your test cases so that you can get a slightly nicer output in Eclipse. The gotcha is that you need to annotate your test class with @RunWith using the Parameterized runner, and it looks like you c...0

I use terminal alot, so it was frustrating to me to deal with gedit's inconsistent behavior between having a window open and when one was not. I ended up searching around, and finding a way of getting around this. I've created this bash script, and aliased it to gedit, and I've slowly been expand...
I wasn't happy with this design, because it forced me to collect all the actions in one place, and because it is not very loop-friendly.
Does the interface really force you to collect all the actions in one place or do you not understand how to do it differently? This is where you should sh...
