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.

I was working on a post and wanted to embed a Fiddle to show an example. I’m currently using GitHub Gist Shortcode plugin to embed gists and tough there maybe something similar for JSFiddle, but after a quick search I couldn’t find anything available in the Plugin Directory.

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.
