  • UBlock Origin and custom filters - Mini tutorial

    Several months ago, I wrote a review of UBlock Origin. It's a powerful, nerdy browser extension, available across the wider range of browsers out there, with the sacred purpose of making the Internet palatable for intelligent use. It does so by being a sophisticated adblocker and content blocker.

    Since, I've received requests for additional tutorials - and also found myself tackling a few real-world issues with somewhat overzealous content blocking. For example, on Bing images, if I clicked on an image, they would show up for a second, flicker and then disappear. Not consistently - but always with UBlock Origin active. So I used this opportunity to write a little guide on how to create custom filters. Let's have a look.

  • apt-key Is Deprecated. How To Add OpenPGP Repository Signing Keys Without It On Debian, Ubuntu, Linux Mint, Pop!_OS, Etc.

    This article explains how to securely add OpenPGP keys and third-party APT repositories on Debian, Ubuntu, and Linux distributions based on these, like Linux Mint, Pop!_OS, Elementary OS and so on, to replace the deprecated apt-key.

    When you try to add an APT repository key using apt-key on Debian, Ubuntu and Linux distributions based on these, you'll see the following message: "Warning: apt-key is deprecated. Manage keyring files in trusted.gpg.d instead (see apt-key(8))".

  • How to count lines of source code in Linux

    For various reasons you may want to know in how many lines of code given open-source software is implemented. For example, you want to estimate the effort devoted to developing a particular open-source program. Or you want to gauge the size and complexity of a program before trying it. There is some controversy as to using source lines of code (SLOC) as a metric to determine the size of a software program, since existing programming languages differ greatly in terms of clarify and brevity.

    In any rate, if you would like to count the number of source code lines quickly and accurately, you can use a command-line tool called cloc (short for "Count Lines Of Code"). cloc is a Perl program that is dedicated to counting the number of lines of code. To estimate the size of codebase accurately, cloc automatically detects different types of programming/scripting languages, and discounts comment lines and blank lines based on the type appropriately.

  • How to List Directory Contents on Linux - buildVirtual

    When working with the Linux file system, its important to know some of the different ways you can list directory contents on Linux.

The Innovation Lab: A Space for Creative Learning

The reason why we use System76 to power all the computers in the space is because I’m a big supporter of Linux in general, and System76 has been really consistent and helpful. I think the openness of System76 definitely gives the students the ability to experiment and the freedom to break stuff in a creative environment, without being too constrained by proprietary software.

GNOME Foundation and Linux Foundation Leftovers

  • GNOME 40 Beta has been Released

    Anyone looking to test the beta for the upcoming GNOME 40 release can now do so. On the heels of the alpha release of GNOME 40, the developers have announced the availability of the beta, which includes a number of improvements and bug fixes. Of course, the biggest change to GNOME is the new horizontal Activities Overview, which makes for a much-improved workflow on the desktop. With the desktops residing at the top of the Overview, it is now easier to drag and drop an application to the specific desktop you want. It’s far more intuitive and efficient. This new layout also improves usage with touch screen navigation and faster overall performance. Another hotly anticipated change comes by way of how multi-monitor support will work with the new horizontal Activities Overview. GNOME 40 will default to only showing workspaces on the primary display, with the top bar and the Activities Overview on both displays.
