There’s no secret Illuminati-supported foundation to destroy the Internet, it’s just the combination of governments, spy agencies, and giant corporations putting their hands on it each by its own. We are going to see why this is the case.

Is there room for FOSS in the AI, VR, AR, MR, ML and XR revolutions—or vice versa? Will the free and open-source revolution end when our most personal computing happens inside the walled gardens of proprietary AI VR, AR, MR, ML and XR companies? I ask, because that's the plan.

This article describes a step by step procedure to install PHP versions 5.6 and 7.2 on your Ubuntu. After installing the two versions, we will also explain how you can disable one version and enable another version to be treated as the default version by the system.

This tutorial is the first part of a C programming language course on Linux. C is a procedural programming language that was designed by American computer scientist Dennis Ritchie. Please note that we'll be using Linux for all our examples and explanation. Specifically, we'll be using Ubuntu 18.04 LTS.

I studied math in college. Back then, ordinarily, math students didn't have access to the computer lab; pen and paper were all we needed to do our work. But for my one required programming class, I got access to the college computer lab. It was running SunOS with remote X terminals (this was circa 1996). I immediately fell in love with Unix. I fell in love with the command line, X Windows, the utilities—all of it. read more

Do more with less. Learn to use less command in Linux for viewing large files and tracking log files. Most common usage of the less command explained in this tutorial.

At the top of the logical view of a worker host is customer code, which is what Lambda runs for its customers. Mesrobian commented that Lambda supports a number of languages and different runtimes including node, Python, Java, C# and more. Underneath the runtime is a sandbox that hosts the runtime and underneath that is a guest operating system that is running Amazon Linux.

When running commands in a Terminal there are many ways information can be redirected. There are a few redirection conventions usable within a Terminal to make things easier.

Welcome back to the Linux command-line toys advent calendar. If this is your first visit to the series, you might be asking yourself what a command-line toy even is. It's hard to say exactly, but my definition is anything that helps you have fun at the terminal. We've been on a roll with games over the weekend, and it was fun, so let's look at one more game today, Snake! read more

If I lend my USB key containing Tails Linux to an evil Penguin, am I sure to use it again afterwards? Is my LUKS key safe? There is no need for an evil Penguin to force or trick me to tell him my LUKS passphrase (as Tails website warns), he only needs to ask me to use my USB key for just a short while.

An evil Penguin’s idea is to inject a script into the Tails filesystem which is able to reveal the LUKS master key – and eventually send it by the network.

Anaconda is the most popular python data science and machine learning platform, used for large-scale data processing, predictive analytics and scientific computing. Anaconda distribution ships with more than 1,000 data packages, the conda command-line tool and with a desktop graphical user interface called Anaconda Navigator.

I've both asked and been asked about the best way to learn more about artificial intelligence (AI). What should I read? What should I watch? I'll get to that. But, first, it's useful to break down this question, given that AI covers a lot of territory. One important distinction to draw is between the research side of AI and the applied side. Cassie Kozyrkov of Google drew this distinction in a talk at the recent O'Reilly Artificial Intelligence Conference in London, and it's a good one. read more

Timeshift is a GTK3-based, open source, system restore utility which takes incremental snapshots of the system using rsync and hard-links. These snapshots can be restored at a later date to undo all changes that were made to the system after the snapshot was taken. Snapshots can be taken manually or at regular intervals using scheduled jobs.

Microsoft's legal department relies on its vultures (to whom it passes money and patents) to sue its rivals; but other than that, Microsoft is a wonderful company!
