Getting started with Node.js, npm, Coffeescript, Express, Jade and Redis
Posted by Erwin van der Koogh mid-afternoon: June 24th, 2011

To celebrate my move to the Agile Consulting and Training division of Xebia I thought it would be very appropriate to start playing with some hip new technologies.

From their homepages:

Node.js: Evented I/O for V8 JavaScript. (A framework for building completely non-blocking servers in Javascript)
NPM: A package manager for node.
CoffeeScript: A little language that compiles into JavaScript
Express: High performance, high class web development for Node.js
Jade: Node Template Engine
Redis: An open source, advanced key-value store

In this guide I will take very small steps so that you can verify that you are check whether you are still on track.
The result is an extremely performant, scalable and lightweight alternative for web development.

Websockets from scratch – Results from a short techrally
Posted by Jeroen van Wilgenburg in the early morning: December 15th, 2010

Last friday we had a techrally at Xebia. We could pick our subject: MongoDB or Websockets or Canvas. I teamed up with Albert. There also was another websockets team consisting of Mischa, Ron and Frank.
We decided to use Jetty for websockets. No particual reason to pick Jetty, we both heard it did something with websockets and in the end it was an easier solution than the other team picked (jWebSocket).
Since we only had a few hours we were in quite a hurry, but in the end it was so simple we had time to write a blog, listen to Dan North and Albert even redid everthing and more in Python. (more…)

Understanding Google Wave
Posted by Sonny Gill mid-morning: June 8th, 2009

(This blog post gives an overview of the architecture and technical concepts in Google Wave. If you are interested in how to use Google Wave in your applications, seeĀ Developing with Google Wave)

At Google I/O 2009, Google unveiled Wave. Wave is a new way of thinking about online conversations.

Consider the following situations -

  1. You write a blog post. Somebody comes around and posts a really insightful comment. Now, you or the comment author want to convert that comment into an independent blog post.
  2. You have been having a long email discussion with a colleague. Now you would like to invite another colleague to the same. She will need to know the context of the discussion and how it evolved.
  3. You email a few colleagues a draft of an article for review. They all email their comments back to you. A lot of them are suggesting the same changes without realizing that they have already been addressed.

With the tools we are using today such as email, blogs, IM etc., all of the above will require some kind of tedious copy – paste, and manual tracking of the changes being made.

Is there a better way?

The Google Wave model tries to provide a better way (more…)
