Simple Twisted H2 Client

This gist contains a really stupid implementation of a Twisted HTTP/2 client. It opens a connection, uses ALPN/NPN to negotiate HTTP/2, and then sends a single HTTP/2 GET request to the /ip endpoint.

To execute this:

Create a clean virtual environment.
Install the requirements: pip install -r requirements.txt.
Install the development version of Twisted that contains the nextProtocols code.
Execute the code using python h2test.py.

Async Proxy Server

Installation

pip install -r requirements.txt

Run

Run the backend server

Observable React elements with RxJS

Note: if you want to skip history behind this, and just looking for final result see: rx-react-container

When I just started using RxJS with React, I was subscribing to observables in componentDidMount and disposing subscriptions at componentWillUnmount.

But, soon I realised that it is not fun to do all that subscriptions(that are just updating property in component state) manually, and written mixin for this...

Later I have rewritten it as "high order component" and added possibility to pass also obsarvers that will receive events from component.

Federated Chef-server'ish with consul.

Why?

Why not? I thought it'd be interesting, and maybe useful.

Goals

No centralized chef-server
Nodes still know about eachother (so chef-searchs work)
Use consul-templates / services for things that need to be updated 'realtime'
Use chef resources for installation and configuration of the rest
