7 Best Free and Open Source Ruby-Based Web Content Management Systems

A web content management system (WCMS) is software designed to simplify the publication of Web content. In particular, it enables content creators to submit content without requiring technical knowledge of HTML or the uploading of files. A CMS is most commonly used in creating an intranet or in establishing a presence on the Web. This type of software that keeps track of every piece of content on a Web site. Content can be simple text, photos, music, video, documents, or just about anything you can think of. A major advantage of using a CMS is that it requires almost no technical skill or knowledge to manage. Not only do content management systems help website users with content editing, they also take care of a lot of “behind the scenes” work such as automatically generating navigation elements, making content searchable and indexable, keeping track of users, their permissions and security setting, and much more. To provide an insight into the quality of software that is available, we have compiled a list of 7 high quality free Ruby-based Linux WCMS. Hopefully, there will be something of interest for anyone who wishes to manage a website. Read more

  • How to Set Up WireGuard VPN on Ubuntu 20.04 | Linuxize

    WireGuard is a modern VPN (Virtual Private Network) technology that utilizes state-of-the-art cryptography. Compared to other popular VPN solutions, such as IPsec and OpenVPN , WireGuard is faster, easier to configure, and has a smaller footprint. It is cross-platform and can run almost anywhere, including Linux, Windows, Android, and macOS. Wireguard is a peer-to-peer VPN; it does not use the client-server model. Depending on its configuration, a peer can act as a traditional server or client. It works by creating a network interface on each peer device tha

Leaving Mozilla and Recalling One's Job in Mozilla

  • yoric.steps.next()

    The web is getting darker. It is being weaponized by trolls, bullies and bad actors and, as we’ve witnessed, this can have extremely grave consequences for individuals, groups, sometimes entire countries. So far, most of the counter-measures proposed by either governments or private actors are even scarier. The creators of the Matrix protocol have recently published the most promising plan I have seen. One that I believe stands a chance of making real headway in this fight, while respecting openness, decentralization, open-source and privacy. I have been offered the opportunity to work on this plan. For this reason, after 9 years as an employee at Mozilla, I’ll be moving to Element, where I’ll try and contribute to making the web a better place. My last day at Mozilla will be October 30th.

  • Working open source | daniel.haxx.se

    I work full time on open source and this is how. Background I started learning how to program in my teens, well over thirty years ago and I’ve worked as a software engineer and developer since the early 1990s. My first employment as a developer was in 1993. I’ve since worked for and with lots of companies and I’ve worked on a huge amount of (proprietary) software products and devices over many years. Meaning: I certainly didn’t start my life open source. I had to earn it. When I was 20 years old I did my (then mandatory) military service in Sweden. After having endured that, I applied to the university while at the same time I was offered a job at IBM. I hesitated, but took the job. I figured I could always go to university later – but life took other turns and I never did. I didn’t do a single day of university. I haven’t regretted it. [...]    I’d like to emphasize that I worked as a contract and consultant developer for many years (over 20!), primarily on proprietary software and custom solutions, before I managed to land myself a position where I could primarily write open source as part of my job. [...] My work setup with Mozilla made it possible for me to spend even more time on curl, apart from the (still going) two daily spare time hours. Nobody at Mozilla cared much about (my work with) curl and no one there even asked me about it. I worked on Firefox for a living. For anyone wanting to do open source as part of their work, getting a job at a company that already does a lot of open source is probably the best path forward. Even if that might not be easy either, and it might also mean that you would have to accept working on some open source projects that you might not yourself be completely sold on. In late 2018 I quit Mozilla, in part because I wanted to try to work with curl “for real” (and part other reasons that I’ll leave out here). curl was then already over twenty years old and was used more than ever before.

  • What is DevSecOps? Everything You Need To Know About DevSecOps

    Most people are familiar with the term “DevOps,” but they don’t know how to really utilize it. There’s more to DevOps than just development and operational teams. There’s an essential element of DevOps that is often missing from the equation; IT security. Security should be included in the lifecycle of apps.  The reason you need to include security is that security was once assigned to one team that integrated security near the end-stages of development. Taking such a lax approach to security wasn’t such a problem when apps were developed in months or years. The average development cycle has changed quite a bit, though, and apps can be developed in a matter of days or weeks. Outdated security practices like leaving security too late can bring DevOps initiatives to their knees.

  • Nibble Stew: The Meson Manual: Good News, Bad News and Good News

    Starting with good news, the Meson Manual has been updated to a third edition. In addition to the usual set of typo fixes, there is an entirely new chapter on converting projects from an existing build system to Meson. Not only are there tips and tricks on each part of the conversion, there is even guidance on how to get it done on projects that are too big to be converted in one go.

  • Percepio Releases Tracealyzer Visual Trace Diagnostics Solution Version 4.4 with Support for Embedded Linux

    Percepio announced the availability of Tracealyzer version 4.4 with support for embedded Linux. Tracealyzer gives developers insight during software debugging and verification at the system level by enabling visual exploratory analysis from the top down. This makes the software suitable for spotting issues during full system testing and drill down into the details to find the cause. Version 4.4 adds several views optimized for Linux tracing, in addition to a set of visualizations already in Tracealyzer, and leverages Common Trace Format (CTF) and the widely supported LTTng, an open source tracing framework.

  • LLVM Adds A SPIR-V CPU Runner For Handling GPU Kernels On The CPU - Phoronix

    LLVM has merged an experimental MLIR-based SPIR-V CPU runner that the developers are working towards being able to handle CPU-based execution of GPU kernels.  This new SPIR-V runner is built around the MLIR intermediate representation (Multi-Level Intermediate Representation) with a focus of going from GPU-focused code translated through SPIR-V and to LLVM and then executed on the CPU. The runner focus is similar to that of the MLIR-based runners for NVIDIA CUDA, AMD ROCm, and Vulkan, but just executing on the CPU itself. It was earlier this year LLVM added the MLIR-Vulkan-Runner for handling MLIR on Vulkan hardware.

  • Test & Code : Python Testing for Software Engineering 136: Wearable Technology - Sophy Wong

    Wearable technology is not just smart consumer devices like watches and activity trackers. Wearable tech also includes one off projects by designers, makers, and hackers and there are more and more people producing tutorials on how to get started. Wearable tech is also a great way to get both kids and adults excited about coding, electronics, and in general, engineering skills. Sophy Wong is a designer who makes really cool stuff using code, technology, costuming, soldering, and even jewelry techniques to get tech onto the human body.

  • Librsvg's test suite is now in Rust

    Some days ago, Dunja Lalic rewrote the continuous integration scripts to be much faster. A complete pipeline used to take about 90 minutes to run, now it takes about 15 minutes on average. [...] The most complicated thing to port was the reference tests. These are the most important ones; each test loads an SVG document, renders it, and compares the result to a reference PNG image. There are some complications in the tests; they have to create a special configuration for Fontconfig and Pango, so as to have reproducible font rendering. The pango-rs bindings do not cover this part of Pango, so we had to do some things by hand.
