        Magento is an open-source e-commerce platform written in PHP that uses multiple PHP frameworks such as Symfony and Laminas. The platform is flexible and has a large variety of features to build an online store.

        Magento offers a community and enterprise edition. The community edition is available free of charge and is designed primarily for individuals and/or small businesses. The enterprise edition is the paid version of Magento. Compared to the community edition, the enterprise edition has advanced custom features and functionalities and is mainly aimed at medium to large businesses.

        In this tutorial, we will show you how to install the Magento 2.4.4 community edition on Ubuntu 22.04 server, which can be done easily if you follow it step by step.

        C and C++ compiler toolchains make it possible for us software geeks to build amazing things. Did you know that both GCC and Clang offer build-in functionality that aids us in becoming better developers and creating higher quality software? I’m talking about compiler warnings. This article explains how you can enable compiler warnings, when using CMake to generate the build environment.

      • Make Use OfHow to Set Up a TFTP Server on Linux

        TFTP (Trivial File Transfer Protocol) was first described in 1980. It is a fairly old protocol published in June 1981 as TFTP Protocol revision 2 in RFC 783 (Request For Comments) by Karen R. Sollins.

        In the early days, the main goal of TFTP was to send and receive files over a network. In particular, it was used to transfer the files needed during boot to enable systems to boot over a network.

        Here's how you can set up a TFTP server on a Linux machine.

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

        In this tutorial, we will show you how to install PrestaShop on Ubuntu 22.04 LTS. For those of you who didn’t know, PrestaShop is an e-commerce solution that allows you to create your own online shop easily. It is written in PHP, is highly customizable, supports all the major payment services, is translated into many languages and localized for many countries, has a fully responsive design (both front and back-office), etc.

        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 PrestaShop e-commerce platform 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.

        • MozillaReworking our Visual Metrics Processing System – Mozilla Performance

          Our visual metrics processing system used to use two separate machines to produce visual metrics from our pageload tests. In this post, I’ll describe how we moved to a single-machine system that also brought about many other benefits for us.

          Note: If you’ve never heard of visual metrics before, they can be summed up as performance metrics processed from a video recording of a pageload. You can find more information about these from this article titled Improving Firefox Page Load, by Bas Schouten.

        • MozillaMigrating to Browsertime for Performance Testing – Mozilla Performance

          Originally, we used a Web Extension for doing performance testing on Firefox in our Raptor test harness. But, we needed to add new features such as visual metrics, so in this post, I’ll briefly describe the steps we took to migrate Raptor to Browsertime.

          We now have enabled Browsertime by default in our Raptor harness both locally, and in Continuous Integration (CI) but for some time, we needed to use the flag `–browsertime` to enable it. This work started with Nick Alexander, Rob Wood, and Barret Rennie adding the flag in bug 1566171. From there, others on the Performance team (myself included), began testing Browsertime, preparing the Raptor harness, and building up the infrastructure required for running Browsertime tests in CI.

          Our primary motivation for all of this work was obtaining visual metrics. If you’ve never heard of visual metrics before, they can be summed up as performance metrics processed from a video recording of a pageload. You can find more information about these from this article titled Improving Firefox Page Load, by Bas Schouten. Initially, our visual metrics processing system used a two-machine system where one machine would run the test and the other would process the video recordings to obtain the metrics. This worked well for some time until we found some issues with it that were a large point of friction when it came to using our tooling. In Reworking our Visual Metrics Processing System, I describe these issues and how we overcame them. It suffices to say that we now use a single machine in CI, and that those issues were resolved.

      • Unix Men5 Data Security Issues on Linux

        Every tech enthusiast knows that Linux comes with the freedom that hardly any other OS can offer. We don’t even have to get into the benefits that come with a large community and open source philosophy.

        However, some people (especially Linux newbies) tend to think that Linux can’t be harmed by cyberthreats at all.

        Hackers and scammers are getting ever more creative, so let’s talk about the security issues on Linux that can get you and your data in trouble.

      • The Register UKX.org servers updated, among many other X11 bits ● The Register

        X.org has released a bunch of updates, which includes closing two security holes and, yes, this affects Wayland users too.

        A batch of updates to X.org's suite of X11 servers and components just appeared. Among the new features, there were also fixes for two security holes mentioned in an X.org Foundation security advisory, which covers CVE-2022-2319 and CVE-2022-2320.

        Although the X window system is pretty old, it's still everywhere, including on almost every xNix operating system that has a graphical desktop. Wayland users don't get to be smug: they too rely upon XWayland, which is what lets them run most older apps. Together, these mean that X.org version 21.1.4 will be a necessary update for a lot of people, alongside XWayland version 22.1.3.

        I recently have come across the most impressive horror series I've seen in a long time.

        It's best to go into this series as blind as possible, but some context and history will really improve what you get out of it. It's based on the culture around Flipnote Hatena (Flipnote Studio in the US). It was a program for the DSi that allowed anyone to create and share animations with each other. A very unique culture of highly talented people developed there until the service shut down on May 31, 2013 despite being popular.

      • I think Mac OS-X is wrong in this case, and Linux is right

        There was apparently a frantic bug-hunt involving “Project: Lumbergh [1]” yesterday that I was not involved in. From the description of the bug, it certainly sounded like it was a manifestation of “undefined behavior” as “Project: Lumbergh” was actinging differently between Linux and Mac OS-X (our testing and development platforms).
