Performance of Arrays vs. Lists
...ut unless you need to micro-optimise, keep it simple and use List<T> etc.
Of course, this only applies if you are reading all of the data; a dictionary would be quicker for key-based lookups.
Here's my results using "int" (the second number is a checksum to verify they all did the same work)...
Fastest way to flatten / un-flatten nested JSON objects
... because: 1) large data sets need a large amount of memory, page swapping, etc.; and that's not something you can control in JS (i.e. you're at the mercy of the browser) 2) if you want to do CPU intensive work then JS is not the best language. Consider using C instead. There are JSON libraries for C...

Different floating point result with optimization enabled - compiler bug?
... a rounding algorithm that addresses the fact that n.n5, n.nn5, or n.nnn5, etc. (but not n.5) is always inexact. Find the corner case that determines whether some input value rounds up or down and return the rounded-up or rounded-down value based on a comparison to this corner case. And you do need ...
Efficient Algorithm for Bit Reversal (from MSB->LSB to LSB->MSB) in C
...ttention since it deals with a simple problem that requires a lot of work (CPU cycles) even for a modern CPU. And one day I also stood there with the same ¤#%"#" problem. I had to flip millions of bytes. However I know all my target systems are modern Intel-based so let's start optimizing to the ex...

The purpose of Model View Projection Matrix
...u again have to calculate the positions of window, hood, headlight, wheels etc., in the car with respect to new world.
See this video to understand the concepts of model, view and projection. (highly recommended)
Then see this to understand how the vertices in the world are represented as Matrices...
What is an example of the simplest possible Socket.io example?
...ke a few minutes depending on the speed of your network connection / CPU / etc. To check that everything went as planned, you can look at the package.json file again.

"socket.io": "~1.1.0"
}

How the single threaded non blocking IO model works in Node.js
...l open/read/write operation on devices and resources (sockets, filesystem, etc.) managed by the file-system don't block the calling thread (as in the typical synchronous c-like model) and just mark the process (in kernel/OS level data structure) to be notified when new data or events are available. ...
What's the point of having pointers in Go?
...reeNode {
value int
left *TreeNode
right *TreeNode
}
Java, Python etc doesn't have this problem because it does not allow you to embed composite types, so there is no need to syntactically differentiate between embedding and pointing.
