All things technology. Very popular here on Justinsomnia.
As I was getting perilously close to filling up my old 256GB hard drive, I decided to treat myself to a 512GB Samsung 840 Pro SSD, which created an opportunity to upgrade to the latest Ubuntu, a task I’d neglected for two years. I usually relish Ubuntu’s semiannual releases—that is, until the Unity user interface landed.
Imagine you have two shell scripts in the same directory.
#!/bin/bash echo "I am test1" cp test2.sh test1.sh
#!/bin/bash echo "I am test2" cp test2.sh test1.sh echo "This should not get printed"

I received an email from an editor at Fabrikzeitung, a monthly magazine published in Zurich, Switzerland by Rote Fabrik. They were planning an issue about QR Codes and asked whether I would write an article expanding upon my post, Why does that QR Code go to justinsomnia.org? Of course!

Given that there’s now a significant global audience of people browsing the web with smaller screens, I decided it was time to get up to speed on responsive web design. (If you’re in the same boat, I highly recommend checking out Apple’s developer docs on Configuring the Viewport. It was eye-opening.)
So I’m checking my blog on the hotel wifi, like ya do, and I notice something a little off with the style. There’s a dark colored bar at the top of the page that shouldn’t be there. That’s funny. Maybe a recent Firefox update changed how they treat CSS?
I probably wouldn’t have thought much of it, except my blog had recently been hacked (someone had gained elevated access to my web hosting account and prepended every single PHP file with a base64 encoded rootkit), so I immediately decided to view the source. Sure enough I saw some unfamiliar CSS and JavaScript that had been injected after the <head> tag (reformatted here for readability):
