Django Models and Migrations

LinuxJournal - Thu, 2015, Jul30 - 13:10

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>>

Secure Server Deployments in Hostile Territory, Part II

LinuxJournal - Wed, 2015, Jul29 - 10:11

In my last article, I started a series on some of the challenges related to spawning secure servers on Amazon EC2. In that column, I discussed some of the overall challenges EC2 presents for security compared to a traditional infrastructure and elaborated on how I configure security groups and manage secrets. more>>

Hacking a Safe with Bash

LinuxJournal - Tue, 2015, Jul28 - 08:25

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>>

Huge Package Overhaul for Debian and Ubuntu

LinuxJournal - Thu, 2015, Jul23 - 14:55

Debian and Ubuntu are moving to update all C++ packages with GCC5, which was released in April. GCC stands for Gnu Compiler Collection, and it is used to convert source code to executable code and libraries. These compilers are used to build everything from the Linux kernel to user applications, so it's a far-reaching change. more>>

diff -u: What's New in Kernel Development

LinuxJournal - Wed, 2015, Jul22 - 11:17

There's a slow effort underway to allow virtually any part of the kernel to be extracted into its own shared library, thus enabling users to use any alternative subsystem they please. There's a long history of this, going back to the debate between micro-kernels and monolithic kernels. more>>

Shashlik - a Tasty New Android Simulator

LinuxJournal - Tue, 2015, Jul21 - 12:23

Although the Linux kernel forms the beating heart of the Android operating system, it's still a very different platform from most distros. In fact, beyond the kernel, most of the libraries, services and applications are completely different. While there are hundreds of different Linux distros out there, they all share components from the GNU project. more>>

Embed Linux in Monitoring and Control Systems

LinuxJournal - Mon, 2015, Jul20 - 11:07

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>>

The Controversy Behind Canonical's Intellectual Property Policy

LinuxJournal - Fri, 2015, Jul17 - 12:20

In the world of FOSS, a small change to a license can be a big deal. For users of proprietary software, changes in the EULA are hardly even registered. Those users click "Ok" and forget about it in the blink of an eye. They have accepted that they are severely limited as far as their rights to alter or redistribute the software is concerned. more>>

Non-Linux FOSS: Portable Apps, in the Cloud!

LinuxJournal - Wed, 2015, Jul15 - 21:41

The concept of PortableApps has been around for a long time. It's a great way to take your Windows apps from computer to computer using a USB drive and never worry about being without your favorite program. Honestly, remembering to carry around a USB drive can be a bit of a pain though. more>>

General Relativity in Python

LinuxJournal - Wed, 2015, Jul15 - 10:01

I have covered several different software packages for doing scientific computation in Linux Journal, but I haven't spent as much time describing available libraries and the kind of work that can be done with those libraries. more>>

Look Mom! I'm on the Internet!

LinuxJournal - Mon, 2015, Jul13 - 12:57

Streaming video to multiple people always has been a challenge. Back when Kyle Rankin and I did "Linux Journal Live", we'd use services like ustream or justin.tv in order to accommodate the bandwidth requirements. The problem with those services is that unless you pay significant money, the features are extremely limited. more>>

Android Candy: Google Photos

LinuxJournal - Thu, 2015, Jul09 - 12:56

Google has become the company that we love and can't live without, but at the same time, I think we all worry a little about just how much Google knows about us. With that caveat, it's hard to ignore Google's newest offering: Google Photos. more>>

One Port to Rule Them All!

LinuxJournal - Mon, 2015, Jul06 - 09:22

I was chatting with Fred Richards on IRC the other day (flrichar on freenode) about sneaking around hotel firewalls. Occasionally, hotels will block things like the SSH port, hoping people don't abuse their network. Although I can respect their rationale, blocking an SSH port for a Linux user is like taking a mouse away from a Windows user! more>>

Privacy Is Personal

LinuxJournal - Thu, 2015, Jul02 - 07:00

Try to nail two boards together with your bare hands.

Can't be done. You need a hammer. But the power is not the hammer's. It's yours, because the hammer is your tool. As a tool, it becomes part of you. That's what tools do: they enlarge your capacity for action and effect.

That capacity is called agency. To have agency is to operate with effect in the world. more>>
