  • My Firefox addons as of Firefox 86 (and the current development version)

    I was recently reminded that my most recent entry on what Firefox addons I use is now a bit over a year old. Firefox has had 14 releases since then and it feels the start of January 2020 was an entirely different age, but my Firefox addons have barely changed in the year and a bit since that entry. Since they have updated a very small amount, I'll repeat the whole list just so I have it in one spot for the next time around.

  • Delegation of responsibility for spec finalisation

    Sean is a natural choice for me to delegate this task to. He has been involved in the development of the Gemini specification for longer than anybody other than myself - he was the first person to actually implement the protocol in software, transforming it from the largely academic thought experiment that I had created it as into an actual real world project. He is the developer of a Gemini server (GLV-1.12556) and the admin of a server running it (gemini://gemini.conman.org), which means the details of the specification are of direct and practical relevance to him. He has a long-standing presence in Gopherspace, where the Gemini project was born, and therefore understands and appreciates the value of simple-by-design systems with limited scope. Finally, he has an excellent track record of constructively engaging with the mailing list even at its busiest and most frantic, which certainly can no longer be said for me. For all these reasons I trust him to make good decisions on the basis of careful consideration.

  • A Saturday waste of CPU cycles: building time_t values

    It was bad enough trying to split up all of those date strings into their constituent parts - year, month, day - all of that stuff. But, then when I tried to consistently turn them back into a time_t, I ran into a bunch of other problems. That lead to the post called time handling is garbage. That then lead into the followup post three months later which talked about making time_t values without using mktime and the TZ variable.

Open source PinePhone modem firmware now supports audio, GPS, and power management

Most modern smartphones actually run two different operating systems – there’s the one you interact with directly and there’s the firmware running on the modem system-on-a-chip, which is basically like its own little computer. So even a phone like the PinePhone that’s designed to run free and open source (usually Linux-based) operating systems might ship with closed-source, proprietary firmware installed on the phone’s Quectel E25-G modem. But a few months ago a small team of independent developers released an open source alternative. It was a bit buggy at the time, but it was mostly free of proprietary “blobs.” Since then, developers Biktor and Konrad Konrad have continued working on their software, and it’s now pretty close to being a fully functional replacement for the PinePhone’s default modem firmware.

  • Lukas "lzap" Zapletal: Crop and resize video to get rid of borders

    We stream our community demos on youtube via Google Meet and there are borders on each side which makes the content to be smaller and less readable. Luckily, it is in the middle of the screen, so the following command will crop the image to its 1/1.29 of the size, stretch it back to 720p and reencodes it for YouTube copying the audio stream.

  • Linux Logical Volume Manager (LVM) tutorial

    Logical Volume Manager (LVM) is used on Linux to manage hard drives and other storage devices. As the name implies, it can sort raw storage into logical volumes, making it easy to configure and use. In this guide, you'll learn how LVM works on Linux systems. There's no better way to learn about LVM than simply running through an example, which is exactly what we'll do in the steps below. LVM works the same on any Linux distribution, so you can use any of the commands below on your own system. Follow along with us as we use LVM to create partitions, physical volumes, a virtual group, logical volumes, and filesystems on a hard disk. We'll also show how to mount, extend, and remove our newly created logical volumes. By the end of this tutorial, you'll have a full understanding of how to use LVM and apply your own configurations.

  • How To Install macOS in a Virtual Machine on Ubuntu Linux

    QEMU is a virtual machine emulator and virtualizer which is quite similar to VMware and VirtualBox on Windows. Users often use QEMU alongside KVM as it provides a natively implemented virtual machine on the Linux kernel. The major advantage of QEMU is that it is very easy to set up and manage. Also, creating virtual machines from the command line has never been simpler with QEMU. You can also use a GUI interface with QEMU/KVM, and the preferred GUI manager of choice is virt-manager. Running virtual machines will provide you so with many other benefits as well. After you have finished testing a QEMU/KVM virtual machine and no longer need it, you can easily delete the virtual disk file associated with the virtual machine.

  • Grep Exclude Term

    Global regular expression print is a versatile terminal-based utility. As the name shows that it helps in searching the text within the file with the help of regular expressions. Grep is firstly originated as a Unix utility to run on that operating platform. After Linux configuration, it can access many applications on this operating system. Most Grep functions are included in the matching of the text of the file present in the command. Exclude function is also as useful as matching any pattern and displaying it because it helps remove the particular match from the file. It helps to exclude the word or words from the lines in a file. We can get help from the man page in the system by applying the below-appended command.

  • How to install Docker containers via Cockpit on Ubuntu 20.04 LTS

    The Cockpit is an easy solution to manage server resources remotely using the graphical web interface. It is not only light in weight but also present to install in most of the Linux repositories such as in popular Ubuntu, RedHat, Fedora, and CentOS to install with just a single command. Well, if we talk about Docker container management in Cockpit, then this really helpful to easily manage virtual machines or containers graphically. Yes, we can install and delete containers using few mouse clicks. No need to go through the command line to manage them. However, in Ubuntu 20.04 the Docker package for Cockpit is not available to install but we can do that manually by directly installing its Deb file. Here, we let you know how to do that in this tutorial.

  • How to check if a port is open on remote Linux system

    When installing or configuring an application in the Linux system, the associated port should also be open which allows the application for external access. If the application port is not open, it will make the program throw errors and hence malfunction. For instance, when you configure the Apache Web server on Linux, you must open ports 80 and 443 that listens to incoming connections for Apache on the firewall, and that allows users to access websites hosted on your web server through the browser.

Best Clipboard Monitoring Apps for Linux

This article will cover a list of useful “clipboard monitoring” apps for Linux. Some desktop environments have built-in support for clipboard monitoring and they provide clipboard monitoring panel applets by default. The term “clipboard monitoring” refers to the practice of keeping a track / log of content copied on your desktop through keyboard shortcuts and mouse interactions. Since clipboard monitoring tools keep a history of copied content, you can review entries in the clipboard history and re-use / paste content that was copied earlier. Read more
