His zeal and talent for explaining is remarkable. I’ve been enjoying the “60 Second Scratch” screencasts (explanatory videos) he has been uploading to YouTube in the past two weeks. For example, check out this little gem:

Take Linux From Zero to Boot in Less Than a Second

Some of us here at FOSS Force don’t mind waiting for a computer to boot. It reminds us of the old days when, after turning on the TV, radio or record player, we had to wait for the tubes to warm up.

Booting Linux

At 2015’s Embedded Linux Conference Europe, Jan Altenberg, who works for Linutronix in Germany, explains how Linux can be optimized to boot in less than one second. Find out more in this fascinating video.

Eight Things to Do After Installing Linux Mint Xfce 18.x

After you get Linux up and running on your computer, there are still a few things left to do. Here’s a short list that newcomers might find helpful.

Linux for Newcomers

Those who are new to Linux might just go to work right away after installing, or having someone else install, GNU/Linux. However, there are a few things you should do first. Some of them, such as updating your system and activating the firewall, are essential. Others are just things you do to customize your Linux experience.

Here’s a short checklist of things to do after you get Linux up-and-running on your computer. You should consider the first two items on this list as being required, with all the other items being optional. The list is specific to Linux Mint 18.x Xfce Edition, so if you’re using another flavor of Linux, you’ll be better off searching for another list.

Dear CIO: Linux Mint Encourages Users to Keep System Up-to-Date

Regardless of what you may have read elsewhere, the Linux Mint team takes security very seriously and wants you to keep your system up-to-date.

Linux Mint 18.0 Update Manager

Swapnil Bhartiya gets it wrong.

Let me start by pointing out that Bhartiya is not only a capable open source writer, he’s also a friend. Another also: he knows better. That’s why the article he just wrote for CIO completely confounds me. Methinks he jumped the gun and didn’t think it through before he hit the keyboard.

The article ran with the headline Linux Mint, please stop discouraging users from upgrading. In it, he jumps on Mint’s lead developer Clement Lefebvre’s warning against unnecessary upgrades to Linux Mint.

Have you often considered quitting your day job to begin an exciting career as a filmmaker? You don’t need the resources of a Hollywood studio anymore. In fact, you can do it all with free and open source software.

The Video Screening Room

Blender is a very popular 3D animation program, but not many people know that this open source, cross platform software also works well as a video editor. Some people consider Blender to be the best open source video editor available. (See the comments at the end of this article on Opensource.com).

Ghost Blogging With a Pi

Even you could become a world famous blogger. The lightweight blogging platform Ghost and a Raspberry Pi is all it takes.

The Raspberry Pi Report

I’ve read that a fun and easy thing to do with a Raspberry Pi is to set it up as a dedicated blog server. I’ve never really had my own blog, so I decided I would give this project a shot. I hope that this article serves as a guide for those of you who would like to start a blog or who have a Raspberry Pi that’s not doing anything and are looking for a worthy project.

Ghost logoHardware: I’m using a Raspberry Pi Model 2 B with a 32-bit SanDisk micro SD card. The reason for using the Model 2 B is because I happened to have one that wasn’t currently being used. Also, I wouldn’t need any of the extras, like Wi-Fi. that the Raspberry Pi 3 brings to the table since it will be connected via Ethernet and SSH.

Krita 3.01 Beta Released

Around since 2005, and with its Kiki the Cyber Squirrel mascot since 2012, Krita is a free and open source raster graphics editor designed to be a digital painting application similar to Corel Painter.

The popular Krita painting program keeps getting even better. This new beta release of 3.01 includes features added from Google Summer of Code programmers. This screencast does a very good job explaining the new features, including new animation tools.

Installing BlackArch Linux on a Raspberry Pi

Would you like to use a Raspberry Pi as a topflight security tool? Here’s how to install BlackArch Linux on a Pi to get you on your way.

The Raspberry Pi Report

Currently Kali Linux is the de facto OS for those looking to do security research or penetration testing, but that could be changing in the months and years to come. This month BlackArch Linux, another penetration testing OS, released new ISOs that could put it ahead of Kali. BlackArch now includes over 1,500 tools for penetration testing and security research as well as support for kernel 4.7.1. In the months to come, I’ll write about using select tools from BlackArch on the Raspberry Pi, but in order to get to that point, we first need to install it. Instead of taking any credit for the install steps or reproduce them over again, I’m simply going to provide links to the same steps that I found and followed which lead me to a successful install of both Arch Linux and BlackArch on my Raspberry Pi 3.
