# Description: Simple demo to showcase Redis PubSub with EventMachine
#
# Update 7 Oct 2010:
# - This example does *not* appear to work with Chrome >=6.0. Apparently,
# the WebSocket protocol implementation in the cramp gem does not work
# well with Chrome's (newer) WebSocket implementation.
#
# Requirements:
# - rubygems: eventmachine, thin, cramp, sinatra, yajl-ruby

Webhook using self-signed certificate and Flask (with python-telegram-bot library)

'''Using Webhook and self-signed certificate'''
# This file is an annotated example of a webhook based bot for
# telegram. It does not do anything useful, other than provide a quick
# template for whipping up a testbot. Basically, fill in the CONFIG
# section and run it.
# Dependencies (use pip to install them):

ElasticSearch Multi-Select Faceting Example
This is an example how to perform multi-select faceting in ElasticSearch.
Selecting multiple values from the same facet will result in an OR filter between each of the values:
(facet1.value1 OR facet1.value2)
Faceting on more than one facet will result in an AND filter between each facet:
(facet1.value1 OR facet1.value2) AND (facet2.value1)
I have chosen to update the counts for each facet the selected value DOES NOT belong to since we are performing an AND between each facet. I have included an example that shows how to keep the counts if you don't want to do this (filter0.sh).

Akka Cluster Implementation Notes

Akka Cluster Implementation Notes

Slightly disorganized but reasonably complete notes on the algorithms, strategies and optimizations of the Akka Cluster implementation. Could use a lot more links and context etc., but was just written for my own understanding. Might be expanded later.

Links to papers and talks that have inspired the implementation can be found on the 10 last pages of this presentation.
