Wed, 09/17/2014 - 17:45

If you're like me (and you're a Linux Journal reader, so you may actually be like me), you probably rotate through your cell phones and/or tablets every couple years. These little devices are so convenient and have been consistently dropping in price, while their power continues to go up, so you may have a few older devices sitting in a drawer. more>>

I am a visual learner. When I try to teach something, I naturally like to use visual examples. That usually involves me working for hours to create flowcharts in Google Docs using the drawing program. Yes, it works, but it's a very cumbersome way to create a flowchart. Thankfully, I recently discovered Lucidchart. more>>

Thu, 09/11/2014 - 20:12

Text expansion and hotkey automation are the sort of things you don't realize you need until you try them. Those of you who ever have played with system settings in order to change the function of a keystroke on you system understand the value of custom hotkeys. more>>

diff -u: What's New in Kernel Development

Wed, 09/10/2014 - 22:16

Android Candy: Quit Thumbing Your Passwords!

Thu, 09/04/2014 - 20:14

I use my phone more often to log in to on-line accounts than I use a computer. I can assure you it's not because typing passwords on a tiny keyboard is fun. For most of us, we just have instant access to our phones at any given time during the day. more>>

I'm writing this in a hotel room entered through two doors. The hall door is the normal kind: you stick a card in a slot, a light turns green, and the door unlocks. The inner one is three inches thick, has no lock and serves a single purpose: protection from an explosion. more>>

Thu, 08/28/2014 - 18:34

Gah, so frustrating! Ten years ago I wrote a rather popular book called Wicked Cool Shell Scripts, and I'm working on a new edition—a Tenth Anniversary release. There are lots of new scripts, entirely new chapters and updates to the older stuff. more>>

Tue, 08/26/2014 - 21:09

Vibrations and wave motions describe many different physical systems. In fact, most systems that dissipate energy do so through waves of one form or another. In this article, I take a look at gvb (Good ViBrations,, a Linux application you can use to visualize and model wave motion and vibrations. more>>

Wed, 08/13/2014 - 19:30

Non-Linux FOSS: a Virtualized Cisco Infrastructure?

Mon, 08/11/2014 - 19:32

We're all familiar with the idea of virtualized computers. Not only are they a great way to better utilize resources in a server room, but they also allow you to create and destroy servers in the blink of an eye. That's perfect for a lab or training environment. Unfortunately, it's always taken a rack of actual hardware to create a training lab for Cisco hardware. more>>
