Encrypt Your Dog (Mutt and GPG)

I have been focusing a lot on security and privacy issues in this year's columns so far, but I realize some of you may expect a different kind of topic from me (or maybe are just tired of all this security talk). Well, you are in luck. more>>

Practical Tiny Core in the Fire Service

Open Axiom

Several computer algebra systems are available to Linux users. I even have looked at a few of them in this column, but for this issue, I discuss OpenAxiom. OpenAxiom actually is a fork of Axiom.

Give new life to old phones and tablets with these tips!

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.

Lucidchart

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.

Android Candy: Quit Thumbing Your Passwords!

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>>

Stuff That Matters

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>>
