The plan here is to investigate the network efficiency of HTTP/2.0 versus HTTP/1.1 by gently hitting Twitter's API. The above script does 5 HTTP requests to Twitter and gets the responses.

In my tests I'm showing an insane different, whereby HTTP/2.0 transfers 250 kB of data and HTTP/1.1 transfers 2.2 MB. This difference seems insane to me, so I'd like to work out why it's happening.

To run this, you'll need Python 3.3. Install the requirements listed in requirements.txt, and then go to Twitter's API page and set up an application. Get the values listed in the script for your application, fill them in, and run them, using Wireshark to check how much traffic was sent. Let me know what you find!

A Thankyou To Google

Dear Google,

I'd just like to thank you for disabusing me of the idea that JSON is under some requirement of well-formedness. I'd been labouring under the tyrannical misapprehension that some standards body had written down how JSON was supposed to work and that if I wanted to claim I was using JSON I would have to comply with that specification.

However, I today received a bug report indicating that a project to which I contribute was unable to make HTTP requests your Google Flights website could understand. I found this perplexing, but my eyes were opened when I saw your HTTP request. In particular, I enjoyed your freeform and inclusive definition of JSON. Allow me to show you what you've called JSON by showing you my SPDY request:
