How to Install R in CentOS 5.6

R is in EPEL (Extra Packages for Enterprise Linux):

EPEL (Extra Packages for Enterprise Linux) is a volunteer-based community effort from the Fedora project to create a repository of high-quality add-on packages that complement the Fedora-based Red Hat Enterprise Linux (RHEL) and its compatible spinoffs, such as CentOS and Scientific Linux.

As part of the Fedora packaging community, EPEL packages are 100% free/libre open source software (FLOSS).

All you need to install R is to add the EPEL repository and then install R the same way you do with any other package: Continue reading →

JSFiddle Shortcode

JSFiddle Shortcode is a WordPress plugin to help you to easily embed Fiddles in your posts.

Withdrawing Earnings from oDesk: Local Currency Wire Transfer VS Payoneer Debit Card

oDesk released Local Wire Transfer recently, a payment method that allow you to receive money directly into your bank account, in your local currency. In this post I’ll attempt to make a comparison between Local Wire Transfer and Payoneer’s Prepaid Master Card, another payment method.

First, some numbers about the two methods: The minimum amount of money you can withdraw using Local Currency Wire Transfer (COP) is $51 (plus a $3.99 fee). With Payoneer the minimum amount is $20 (plus a $2 fee). You can check Payoneer fees here.

Now, let me tell you a story… or something like that:

Running Firefox with Different Profiles

This post tells nothing new but it’s something I must have tried a long time ago.

Firefox is the best browser I know…. but is not perfect. One of the major problems I experience with Firefox is that when you start installing some extensions and combine that with a lot of tabs opened at the same time, things stop being nice and you start feeling like you’re running the browser in your grandma’s computer.

Most of the extensions I use are for development purposes only, so one way to have a better browsing experience is to have separated profiles. A profile for normal browsing (email and blog reading, facebook, twitter, …) and another for development with all the nice extensions I use when working. Now you can get rid of your  development stuff by closing the browser instance that is using that profile and keep surfing the web with the lighter profile, or viceversa.

How to Install Aptana Studio 3 in Fedora 15

A friend told me about Aptana Studio, an Open Source web development IDE. I think I used it years ago but then switched to NetBeans for some reason. After taking a look at Aptana’s website I decided I wanted to try it again. Below are three simple steps I followed to install Aptana Studio in Fedora 15.

  1. Download Apatana Studio 3 from http://www.aptana.com/products/studio3/download and extract the content of the downloaded zip file.
  2. Move Aptana Studio 3 to a standard location 
    mv Aptana Studio 3 /usr/local/aptana-studio-3
  3. Create a file /usr/share/applications/aptana.desktop with the following content:
    [gist id=1024232]

Although Aptana can be easily run just after you download the application, I like to have menu entries for most of the software I use, hopefully I’m not the only one who thinks like that and the above can help them.
