arobson / RingBuffer.cs

Created January 24, 2011 05:37

This is a very different approach I took from initial attempts that relied on volatile arrays and a crap ton of pointers. This is more fun :)

	using System.Collections.Generic;
	using System.Diagnostics;
	using System.Linq;

arobson / OWINFileServer.cs

Created January 26, 2011 20:05

A contrived but fun example of how to build a OWIN compliant file server using Symbiote.

	using System;
	using System.Collections.Generic;
	using Symbiote.Core;
	using Symbiote.Http;
	using Symbiote.Http.Impl;
	using Symbiote.Http.Owin;
	using Symbiote.StructureMap;
	using Symbiote.Daemon;
	using Symbiote.Messaging;
	using Symbiote.Actor;

arobson / RiakDemo.cs

Created February 8, 2011 01:27

A really cheesy example of how the Repository and KeyValue APIs work for Riak.

	class Program
	{
	static void Main(string[] args)
	{
	Assimilate
	.Core<StructureMapAdapter>()
	.AddConsoleLogger<RiakService>( x => x.Info().MessageLayout( m => m.Message().Newline() ) )
	.Messaging()
	.Daemon( x => x.Arguments( args ).Name( "Riak Demo" ) )
	.Riak( x => x.AddNode( r => r.Address( "192.168.1.100" ) ) )

arobson / http_server1

Created June 17, 2011 19:07

Snippet of the 'Dynamic' HTTP server that accomodates RESTful requests and static content using Misultin.

	handle_request(Req) ->
	#req{uri={_,Uri}} = Req:raw(),
	Ext=filename:extension(Uri),
	handle_request(Req, Uri, Ext).

	handle_request(Req, _Uri, []) ->
	Segments = Req:resource([urldecode]),
	Method = get_atom(Req:get(method)),
	[Resource\|Arguments]=Segments,
	ResourceModule = get_atom(Resource),

arobson / coffee-pubsub

coffeescript pub/sub demo for rabbitmq

	sys = require "sys"
	rabbit = require "amqp"

	console.log "Connecting to rabbit..."
	connection = rabbit.createConnection { host: "localhost", port: 5672 }

	connection.on "ready", () ->
	exchangeOptions = { type: "fanout", autoDelete: true }

Improved Approach To Limiting Asynchronous Calls with Rx

	Action<IList<XElement>> saveAction = SaveChunk;
	var loader = new BulkPostLoader(@"e:\stackoverflow\062010 so\posts.xml");
	var batches = loader.BufferWithCount(5000);
	var results = batches.Select(x => saveAction.BeginInvoke(x, null, null));

	results
	.Aggregate(new HashSet<IAsyncResult>(), (set, result) =>
	{
	set.RemoveWhere(x => x.IsCompleted);
	set.Add(result);

arobson / binder.js

Created September 2, 2011 05:53

An ugly POC for decoupled 'binding' in Javascript

	var DomWriter = function (target, namespace) {
	var instance = this;
	var template = namespace;

	var coalesce = function( value, defaultValue ) {
	return typeof(value) != 'undefined' ?
	value : defaultValue;
	};

	this.isObject = function( value ) {

	zlib = require 'zlib'
	module.exports = (robot) ->

	robot.respond /(stack\|ss) ?(find:.) ?(tags:.)/i, (msg)->

	query = msg.match[2]
	query2 = msg.match[3]
