# `$ whoami`

Programmer. I code mostly in JS(/Node.js), Go, Python. I love making things go faster!

I make and contribute to lots of open-source projects.

And i enjoy building distributed systems.

## My projects

- [Steady.js](https://github.com/lafikl/steady.js) : Featured on Hacker news, #1 Most trending open-source project at Github.

- [WPTProxy](https://github.com/lafikl/wptproxy): Will be used by [webpagetest.org](webpagetest.org) itself.

- [Fluent](https://github.com/lafikl/fluent)

- [PerfBar](https://github.com/lafikl/perfbar): Will be demo-ed at [Velocity](http://velocityconf.com/velocityeu2014/public/schedule/detail/38145) next monday.

# What is Node.js?

> Node.js is an open source, cross-platform runtime environment for server-side and networking applications.

> Node.js provides an event-driven architecture and a non-blocking I/O API that optimizes an application's throughput and scalability. These technologies are commonly used for real-time applications.

> Node.js uses the Google V8 JavaScript engine to execute code, and a large percentage of the basic modules are written in JavaScript. Node.js contains a built-in library to allow applications to act as a Web server without software such as Apache HTTP Server or IIS.

# When you should use it:

- Real-time applications

- Web services

- [Isomorphic applications](http://nerds.airbnb.com/isomorphic-javascript-future-web-apps)

- [Front-end API](http://www.nczonline.net/blog/2013/10/07/node-js-and-the-new-web-front-end/)

- Sharing code between the front-end and back-end

- High concurrency and small cost.

- Speed of development

# Some of Node's major users:

- Groupon

- SAP

- LinkedIn

- Microsoft

- Yahoo

- Walmart

- PayPal

- Box

- Airbnb

# Success Stories:

- [LinkedIn Moved From Rails To Node: 27 Servers Cut And Up To 20x Faster](http://highscalability.com/blog/2012/10/4/linkedin-moved-from-rails-to-node-27-servers-cut-and-up-to-2.html)

- [Eran Hammer was bored last black friday.](https://twitter.com/eranhammer/status/407784258170667009) 

- **Walmart**: Deploying code while 200,000,000 users were online! >=1% CPU utilization

- **Groupon**: Page load times dropping by a whopping 50%, and reduced downtime! They were using Rails.

- **PayPal**: 

  - Built almost twice as fast with fewer people.

  - Written in 33% fewer lines of code.

  - Constructed with 40% fewer files.

  - Double the requests per second vs. the Java application.

  - 35% decrease in the average response time.
