JavaScript hashmap equivalent
...yourself manually, and use the resulting strings as keys for a regular JavaScript dictionary. After all, you are in the best position to know what makes your objects unique. That's what I do.

Sample conversion code:

How to set timeout for http.Get() requests in Golang?
...ial function which wraps around DialTimeout.
Something like (completely untested) this:
var timeout = time.Duration(2 * time.Second)
func dialTimeout(network, addr string) (net.Conn, error) {

Check to see if a string is serialized?

What are the differences between a multidimensional array and an array of arrays in C#?
...rd, well that's how it should be. The program is shown below, FYI this was tested running mono. (The windows timings are vastly different, mostly due to the CLR implementation variations).
On windows, the timings of the jagged arrays are greatly superior, about the same as my own interpretation of w...

How to extract the n-th elements from a list of tuples?

>>> zip(*elements)[1]
(1, 3, 5)
