    • The case of the collapsing calendar

      Recently I quit my job to become 'retired'. This leads to a lot of changes, some more predictable than others. The lock down period and working from home during the last two years already brought some changes, like not having to commute every day and being able to have lunch with my wife.

      • Linux CapableHow to Install AngularJS on AlmaLinux 9 - LinuxCapable

        Angular is a popular, open-source web application framework for building mobile and desktop apps. It was developed in 2009 by Google to help developers design complex applications from scratch without having expert knowledge of coding languages like C# or Java. It can take up valuable time when you want something simple with little functionality at first but grow as your project develops over the years.

        In the following tutorial, you will learn how to install Angular on AlmaLinux 9 using the command line terminal using the NodeSource repositories as the source for NodeJS and NPM.

      • ID RootHow To Install Nextcloud on Ubuntu 22.04 LTS - idroot

        In this tutorial, we will show you how to install Nextcloud on Ubuntu 22.04 LTS. For those of you who didn’t know, NextCloud is a free open-source self-hosted cloud storage solution. It is very similar to other cloud storage solutions like Dropbox, Google Drive, iCloud, etc. NextCloud also returns the control and security of your sensitive data back to you, thus eliminating the use of a third-party cloud hosting service.

        This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the Nextcloud on Ubuntu 22.04 (Jammy Jellyfish). You can follow the same instructions for Ubuntu 22.04 and any other Debian-based distribution like Linux Mint, Elementary OS, Pop!_OS, and more as well.

        • Nate GrahamThis week in KDE: a mad bugfixing spree – Adventures in Linux and KDE

          Plasma 5.25’s first bugfix release came out a few days ago, and the next one is due early next week. Hopefully most of the bugs you folks found will have been fixed! And among those are few 15-minute bugs too.

          Occasionally people ask, “Jeez, it feels like you guys are fixing bugs all the time… shouldn’t they all be fixed by now? Why is your software so buggy?” Thing is, that’s the nature of software. There are always more bugs to fix, no matter how long you work at it. And the more people who use it, the more bugs they’ll find. This is universal, for every piece of software. The best metric is not really “number of bugs fixed,” but rather “egregiousness of bugs fixed.” You want to see that the bugs we fix get weirder and more esoteric over time, which indicates that the basics are becoming more reliable. We’re not all the way there yet, but I believe we are making progress!

      • GNOME Desktop/GTK

        • Builder GTK 4 Porting, Part VII – Happenings in GNOME

          It’s been another couple weeks of porting, along with various distractions.

          The big work this time around has been deep surgery to Builder’s “Foundry”. This is the sub-system that is responsible for build-systems, pipelines, external-devices, SDKs, toolchains, deployments-strategies and more. The sub-system was starting to show it’s age as it was one of the first bits of Builder to organically emerge.

          One of the things that become so difficult over the years is dealing with all the container layers we have to poke holes through. Running a command is never just running a command. We have to setup PTYs (and make sure the TTY setup ioctl()s happen in the right place), pass environment variables (but to only the right descendant process), and generally a lot more headaches.

          What kicked off this work was my desire to remove a bunch of poorly abstracted bits and we’re almost there. What has helped considerably is creating a couple new objects to help manage the process.

          The first is an IdeRunContext. It is sort of like a GSubprocessLauncher but allows you to create layers. At the end you can convert those layers into a subprocess launcher but only after each layer is allowed to rewrite the state as you pop back to the root. In practice this has been working quite well. I finally have control without crazy amounts of argument rewriting and guesswork.

      • 9to5LinuxFirst Look at EndeavourOS ARM on the Raspberry Pi 4

         The EndeavourOS team started working on their ARM port for the distribution about two years ago. Until now, installing EndeavourOS on ARM devices required you to write the latest EndeavourOS ISO image on a microSD card, download the EndeavourOS ARM installation script, and then run the text-based installer that had several stages.

        The previous ARM installer script, which is still available for unsupported devices, was for advanced users, but now anyone can try EndeavourOS on a supported ARM device (Odroid N2/N2+ and Raspberry Pi at the moment of writing this article) thanks to the new ARM installer.

        EndeavourOS Artemis is here about two and a half months after EndeavourOS Apollo to bring you an up-to-date installation medium that contains all the latest and greatest GNU/Linux technologies, starting with the Linux 5.18 kernel series and Mesa 22.1 graphics stack, and continuing with the latest Calamares (3.2.60) graphical installer.

      • Artemis is launched

        We are proud to present you the Artemis release, named after the upcoming NASA mission to the moon and I do refer to that mission for a reason but more on that later.

        Artemis is our regular ISO refresh release, so users who already are running EndeavourOS don’t have to install this release, you already are up-to-date.

        Besides the regular updates and improvements on the ISO and the installation process is this release the first ISO that brings EndeavourOS ARM closer to the main release.

      • Linux Links5 Top Free and Open Source Erlang Web Frameworks

        One of the types of software that’s important for a web developer is the web framework. A framework “is a code library that makes a developer’s life easier when building reliable, scalable, and maintainable web applications” by providing reusable code or extensions for common operations. By saving development time, developers can concentrate on application logic rather than mundane elements.

        A web framework offers the developer a choice about how to solve a specific problem. By using a framework, a developer lets the framework control portions of their application. While it’s perfectly possible to code a web application without using a framework, it’s more practical to use one.

        Erlang is a general-purpose, concurrent, declarative, functional programming language and runtime environment developed by Ericsson, a Swedish multinational provider of communications technology and services. Erlang is dynamically typed and has a pattern matching syntax. The language solves difficult problems inherent in parallel, concurrent environments. It uses sets of parallel supervised processes, not a single sequential process as found in most programming languages.

        Let’s explore the 5 Erlang web frameworks. For each program we have compiled its own portal page, a full description with an in-depth analysis of its features, together with links to relevant resources.

    • TediumIn Defense of “One Week”: A BNL Take That’s Not for Haters

      As many of our regular readers are probably aware, both Ernie and I are massive fans of Canadian folk rock band, Barenaked Ladies. Throughout my youth, teenage years, and early adulthood, their music provided a significant part of the soundtrack of my life. I loved everything the band released and held them in high esteem alongside the likes of “Weird Al” Yankovic and They Might Be Giants. The first BNL song I ever heard was “The Old Apartment,” which I found on one of those CD samplers of relatively new/not yet known records (it also contained “Peaches” by PUSA and “Quiche Lorraine” by the B-52s; I don’t remember where I acquired it). A recent article in Stereogum, part of writer Tom Breihan’s exhaustive look back at every number-one song in Billboard history, took an unbelievably harsh approach, a level of hatred rarely seen outside the Nickelback commentary genre. The takedown, to be blunt, tackled me, and I still have the rugburns on both my knees. As a result, we felt like the time for rebuttal from actual BNL fans was in order. So put on your favorite BNL record (editor’s note: this one is a good choice) and get ready for a blast from the past as we talk about the late ’90s radio hit, “One Week.”

          Today, the U.S. Supreme Court overturned Roe v. Wade, which guaranteed federal constitutional protection of abortion rights in the United States. Access Now condemns the Court’s decision, which has catastrophic implications for human rights in the digital age.

          “With the end of Roe, surveillance capitalists are in a position to weaponize our decision to access reproductive healthcare,” said Jennifer Brody, U.S. Policy and Advocacy Manager at Access Now. “What we search online and where we go can be used to strip our right to autonomy over our body, expression, and life. As surveillance technologies — from smart watches to virtual assistants — continue to proliferate and monitor our every move, our health and humanity are at risk of irreparable damage.”

        On April 28, 2022, the Indian Computer Emergency Response Team (CERT-In) issued Directions under Section 70B of the Information Technology Act, 2000 regarding preventing, responding and reporting cyber incidents. These Directions will become effective on June 27, 2022. SnTHosting, a VPN service provider, has addressed legal representation to MeitY seeking recall of the Directions as they compel a range of entities, including SnTHostings, to surveil their users and collect their personal data, and mandate them to make such data available to CERT-In on demand. IFF has provided legal support in drafting the representation.
