For R fans and infographics lovers out there (I’m one of you), here’s an article that shows how to layout and design an infographic in R. Here’s how the data used to generate it was obtained.
y1 <- round(rnorm(n = 36, mean = 7, sd = 2)) # Simulate data from normal distribution
y2 <- round(rnorm(n = 36, mean = 21, sd = 6))
y3 <- round(rnorm(n = 36, mean = 50, sd = 8))
x <- rep(LETTERS[1:12], 3)
grp <- rep(c("Grp 1", "Grp 2", "Grp 3"), each = 12)
dat <- data.frame(grp, x, y1, y2, y3)

For some time now I’ve been using Atom as a replacement for Kate, KWrite and GEdit, depending on the desktop environment I’m using. That’s because it’s much easier and faster to take notes when you’re formatting with MarkDown. If you’ve never heard about Atom, it’s a text editor from the folks at GitHub and officially described as a “hackable text […]
This short tutorial shows how to configure a Ubuntu 14.04 Cloud server to forward system-generated mails sent to the root account to your email address. Why would you want to forward mails sent to root to an email address? Because most properly-configured Cloud servers are managed using a (normal) user account with sudo (root) privileges. So unless you switch to […]
