Intrigued, I decided to perform additional testing, by performing a small benchmark of ... http://www.ostinelli.net/erlang-listskeyfind-or-proplistsget_value/ Inspired by Joe Armstrong's post, I've recently added websocket support to misultin v0.4, my Erlang library for building fast lightweight HTTP servers. Basically, websockets allow a two-way asynchronous communication between browser and servers, filling the gap that some technologies such as ajax and comet have tried to fulfill in these recent ... http://www.ostinelli.net/misultin-erlang-and-websockets/ Today I've released Misultin (pronounced mee-sul-teen), an Erlang library for building fast lightweight HTTP servers. The first benchmarks are quite satisfying, even though there still is work to do. Here is the simple code for Misultin's Hello World. -module(misultin_hello_world). -vsn('0.1'). -export([start/1, stop/0, handle_http/1]). % start misultin http server start(Port) -> misultin:start_link([{port, Port}, {loop, ... http://www.ostinelli.net/misultin/ Message passing between Erlang nodes is considerably slower than within the same node.

It is at the same time relaxing, enriching and very tiring. Here are some attempts at stone balancing. http://www.ostinelli.net/stone-balancing/ OpenSpime is a protocol, an open XMPP custom extension enabling physical devices to communicate. It has been written with the Internet of Things in mind. A Technical Introduction to OpenSpime OpenSpime Buzz The whole buzz started when the following video was presented. One of the first persons to blog about this was Bruce ... http://www.ostinelli.net/openspime/ I have been involved for some time into realizing Intelligent Virtual Assistants that target business applications. Here's a concept application that was presented by our team at the Savio Event in London, which clarifies a possible use of virtual assistants in a business environment. As you will see, these scarcely ... http://www.ostinelli.net/the-composite-intelligence-of-virtual-assistants/ Is anybody speaking your same language? http://www.ostinelli.net/the-incommunication-series/ A series dedicated to the intuition of the water element.
