I am a newbie to sizzlejs (javascript selctor library) and i would like to know what are the advantages of using sizzlejs instead of jquery core library , Or why they started sizzlejs as a separate project ? IS there fetures that can apply to selectors that cant do with the jquery core library ? ...

Although... the fact that it is a legitimate review but focuses purely on comments may make it a good reference answer for some Meta discussion at some point.
Though, if there are any grammar mistakes, please help me spot them and fix them. There's nothing worse than criticizing someone else's grammar and misspellings than to have some of the same problems.

If you want to get picky to an incredibly insane extent, the following has an extra comma:
>They help any future maintainer (including yourself when it's been 6 months since the last time you looked at the script) to understand what the code does, because programmer time is extraordinarily valuable.
Well, if we're being super picky, the sentence out of context also isn't logical. It implies that comments help the future maintainer because programmer time is valuable.

oop & design-patterns tags you've used are already saying what needs to be done here. At this moment it's a structural code (with some class syntax) and it will be very difficult to expand. Even though it doesn't look like a big project yet and you don't need deep object structures/...
I'm drawing a blank again... there's a postgresql shortcut for generating a number sequence, e.g., {1,2,3... n } in a column but Google always brings me back to create sequence which is totally not the same thing :(

I was wondering, is this the optimal method to check for collisions in a 2d-based game?
I put together a working demo of 2D collisions here: http://jsbin.com/qipezajiwevo/1/ (wsad to move, orange blocks collide).
Currently I use the following code to check for collisions:

You can always go for branchless code:
// 1 = negative
// 0 = positive
public static int isNegative(float val) {
return (Float.floatToIntBits(val)) >>> 31;
}
public enum Direction {
NORTH_EAST, NORTH_WEST, SOUTH_EAST, SOUTH_WEST;
//I had to reorder the directions (or use index mappi...
@Phrancis i know it's not the same, but maybe good enough for the job? SELECT contract_number, status, Count(status) FROM seeded GROUP BY contract_number, status
I'm currently using SVN for my PHP projects. I was thinking I should get my database under version control too, but what's the best way to do that? Do I just make a db-folder in my project in SVN, paste SQL changes into a file called from_1.0_to_2.0.sql and commit?
Is it off-topic if you post a question where your first implementation didn't quite deliver as expected (though it worked) but the later implementation was better (and still asking for review?)
(posting 2nd implementation for review, but leaving the first for reference)
How to NOT write a zombie.
A zombie is a question that remains unanswered. As a question asker, your goal is to avoid writing one.
Beyond meeting the on-topic requirements, I think "good CR questions" can be broken down into several question types.
This answer is longer than I would have liked...
I needed your sanity check. Did not realize the code was broken/not yielding expected results, to begin with. Thank you & accepted. — Phrancis9 secs ago

@Vogel612 That is the way, like I want to implement it. For me the name ReloadPlugin is just not descriptive enough, but I can't think of a better name. Maybe I will clarify it in the XML documentation.
private static final Map<String, Object> MAP = new HashMap<String, Object>() {
{
MAP.put("a", new Object());
}
};
You are first of all, creating an anonymous inner class extending HashMap<String, Object>
then
you are declaring an initialization block, using { ... } on that class, in which you are legally allowed to refer to any final (or Java 8 effectively final) variable
Hence you are referring to MAP, which is still null, because you haven't constructed it yet
And I just learned that anonymous inner classes can have constructors.
I am wondering why the Iterable interface does not provide the stream() and parallelStream() methods. Consider the following class:

private final int capacity;
