The future is encrypted, but your government says that’s not good

The future is encrypted, but your government says that’s not good

On the same day that an article titled Security and Privacy on the Encrypted Network: The Future is Encrypted was published by an information security research and advisory firm called Securosis, Eric Holder, the U.S. Attorney General, was criticizing technology companies for making it more difficult for law enforcement agencies to track and prosecute criminals. That was a not-very-subtle dig […]

Interesting articles on Data Science, and a cool image

It’s very rare that the CEO of a technology outfit that’s based in the West takes an open stance on hot-button geopolitical issues. It’s even rarer that that position is (somewhat) counter to generally held opinion in the West. But that’s what Mark Shuttleworth has done. Remember Mark Shuttleworth? He’s the founder of Canonical, the company behind a very popular […]

How to install TwitteR, a Twitter client for R

How to install TwitteR, a Twitter client for R

Installing packages in R is pretty easy, if you know the name of the package you wish to install. Just pass the name of the package to the install.packages() function. Once that’s done, load the package by passing its name to the library() function. So it’s a fairly easy and straight-forward process, right? But it wasn’t so when I attempted […]

How to install Oracle JRE and make it the default JRE on Ubuntu 14.04

Is systemd as bad as boycott systemd is trying to make it?

From just a purely end-user perspective, systemd is an application that I’ve come to like a lot. And I think that its adoption by all Linux distributions will make it easier to manage Linux systems. But it has come under heavy criticism from some quarters – for trying to be a Swiss-army-knife-type application. One that does practically anything and everything, […]
