Json makes tuples to list

While working on json format, came across something interesting.

sample_list  = [(1,2),(3,4)]

print json.dumps(sample_list)  # [[1,2],[3,4]]

As we can see here, json isnt preserving tuples. On searching, I got to know, JSON doesnt understand tuples. These are the basic data types for json(from Wikipedia )

JSON's basic types are:

• Number (double precision floating-point format in JavaScript, generally depends on implementation)

• String (double-quoted Unicode, with backslash escaping)

• Boolean (true or false)

• Array (an ordered sequence of values, comma-separated and enclosed in square brackets; the values do not need to be of the same type)

• Object (an unordered collection of key:value pairs with the ':' character separating the key and the value, comma-separated and enclosed in curly braces; the keys must be strings and should be distinct from each other)

• null (empty)

Here are some solutions for the same on stackoverflow.

Lesser known Stress testing Utility - Siege

Siege is a HTTP/HTTPS Stress testing tool.

Here is the man page for it.

Here is short intro from the man page -

Siege is a multi-threaded http load testing and benchmarking utility. It was designed to let web developers measure the performance of their code under duress. It allows one to hit a web server with a configurable number of concurrent simulated users.

A basic command for testing a web app locally is

siege http://localhost:8000/?q=pants -c10 -t10s

c -> number of concurrent users
t -> time for running tests for.


Hope it was useful.
