System Status as SMS Text Messages

By Dave Taylor

If you're paying really close attention, you'll remember that in my last article, I was exploring the rudiments of a script that would accept a list of words as input and create a word search grid, suitable for printing. more>>

Libreboot on an X60, Part I: the Setup

By Kyle Rankin

Recently I wrote a review for the Linux Journal Web site on the Purism Librem 15 laptop. The goal of this laptop is to provide a piece of modern hardware that can run 100% free software not just for the OS, but also all device drivers and firmware up to and including the BIOS. more>>

Vagrant Simplified

By Shawn Powers

I admit it, some tools confuse me. I know they must be amazing, because programs don't get popular by being dumb (well, reality TV, but that's another story). I have the same sort of confusion with Vagrant that I have with Wine, Docker, Chef and countless other amazing tools people constantly rave about. So in this article, I'm going to break down Vagrant into its simplest form. more>>

Using tshark to Watch and Inspect Network Traffic

By Mihalis Tsoukalos

Most of you probably have heard of Wireshark, a very popular and capable network protocol analyzer. What you may not know is that there exists a console version of Wireshark called tshark. The two main advantages of tshark are that it can be used in scripts and on a remote computer through an SSH connection. more>>

Where's That Pesky Hidden Word?

By Dave Taylor

I've been promising my 11-year-old for a long time now that I'd write a program that would let you build custom word searches based on a list of words given by the user. I wrote one years and years ago in C, but since I can't find that code any more and wanted to tackle another interesting project for this column, that's what I'm going to look at herein. more>>

Concerning Containers' Connections: on Docker Networking

By Federico Kereki

Containers can be considered the third wave in service provision after physical boxes (the first wave) and virtual machines (the second wave). Instead of working with complete servers (hardware or virtual), you have virtual operating systems, which are far more lightweight. more>>

Django Models and Migrations

By Reuven M. Lerner

In my last two articles, I looked at the Django Web application framework, written in Python. Django's documentation describes it as an MTV framework, in which the acronym stands for model, template and views. more>>

Hacking a Safe with Bash

By Adam Kosmin

Through the years, I have settled on maintaining my sensitive data in plain-text files that I then encrypt asymmetrically. Although I take care to harden my system and encrypt partitions with LUKS wherever possible, I want to secure my most important data using higher-level tools, thereby lessening dependence on the underlying system configuration. more>>

Embed Linux in Monitoring and Control Systems

By Rick Brown

The target vehicle for this project is a vintage intercity transport bus (think Greyhound) whose instrument panel was sparse and mostly nonfunctional. The speedometer cable was twisted off some place back in 40 feet of cable, and the fuel sensor had sunk long ago. What I wanted was an instrument panel more in line with modern practice. more>>

Home Automation with Raspberry Pi

By Bharath Lohray

The Raspberry Pi has been very popular among hobbyists and educators ever since its launch in 2011. The Raspberry Pi is a credit-card-sized single-board computer with a Broadcom BCM 2835 SoC, 256MB to 512MB of RAM, USB ports, GPIO pins, Ethernet, HDMI out, camera header and an SD card slot. more>>

PHP for Non-Developers

By Shawn Powers

After years of making it clear that I'm not a developer in just about every article I've written here at Linux Journal, I do have a confession to make. I can write the "Hello World" equivalent in almost every programming language out there. In assembly, it might have been "1+1", but my lack of advanced skills should be evident. more>>

Secure Server Deployments in Hostile Territory

By Kyle Rankin

Would you change what you said on the phone, if you knew someone malicious was listening? Whether or not you view the NSA as malicious, I imagine that after reading the NSA coverage on Linux Journal, some of you found yourselves modifying your behavior. The same thing happened to me when I started deploying servers into a public cloud (EC2 in my case). more>>

Django Templates

By Reuven M. Lerner

In my last article (February 2015), I explained how to create a simple Django project ("atfproject") and inside that, create a simple application (atfapp). The application worked in that if you went to the URL https://localhost:8000/hello/Reuven, you got the text "hello, Reuven". more>>
