      • TechRadarThe next big Linux update could be something pretty special

        The next big Linux update could be a big deal, according to foundation founder and head honcho Linus Torvalds.

        Tovalds said in the latest update (opens in new tab) on the development of the Linux 5.19 kernel that the “ARM generic kernel work (aka "multiplatform") is pretty much done after 10+ years.”

        He added: “StrongARM platforms remain with their separate kernels, and are expected to stay so, but compared to where things were a decade ago, this is a pretty big step.”

        Steps to install Uptime Kuma open source monitoring solution on Ubuntu 22.04 LTS Jammy JellyFish without Docker to keep eye on your Server.

        Kuma is a very lean monitoring tool for your own environment and many more. ICMP (ping) requests can be sent super easily or simply check whether a website is accessible. Even open TCP ports can be included super easily in the monitoring. It is a self-hosted monitoring tool like “Uptime Robot”.

      • ByteXDHow to Backup and Restore your Linux system with Timeshift

        Despite having a relatively steep learning curve, Linux distributions are one of the best operating systems you can use compared to their main alternatives, Windows and macOS. Linux is free and open-source.

        It is rated as one of the most secure OS today and has thousands of software packages available for installation. It’s also possible to run Windows applications on Linux with the help of apps like Bottles and Wine.

        However, like with any piece of software, anything can go wrong with Linux.

        With one sudo command, you can permanently delete critical settings and packages on your system or make your OS un-bootable. Sometimes, normal system operations can cause these challenges. Maybe you are trying to install another Desktop environment that re-configures your entire system.

        That leaves you wondering if it is possible to reinstate your system to a previous state. Well, that is possible with Timeshift.

      • TechRepublicHow to install Docker Desktop and enable Kubernetes support

        Containerized applications are only going to increase in popularity year by year, which means every developer and admin has to know how to deploy and manage those containers and services. To that end, several GUI tools have been developed and released to make the job considerably easier.

        But not all of those tools are created equal. To date, my absolute favorite Docker GUI is Portainer, but there are plenty of other options. One such application is the official Docker Desktop GUI that’s available for Linux, macOS, and Windows. Although Docker Desktop doesn’t give you nearly the amount of features and controls found in Portainer, it’s still a great GUI that allows you to manage running containers, pull and manage images, deploy containers from images, create development environments, add Kubernetes support, and even expand the feature set with extensions.

        I want to walk you through the installation of Docker Desktop on Pop!_OS Linux and show you how to enable Kubernetes support and even extend it with Portainer.

        While they have always been secure, fast, and minimalistic, Chromebooks only supported progressive web apps in the beginning. That changed six years ago when Google announced the arrival of Android apps for Chromebooks, supercharging these small machines with millions of apps available for the mobile Android ecosystem (via Google). The apps can send notifications, work offline, and even allow touch input.

        Linux is a multi-user environment where numerous user accounts can be added and used like most operating systems. However, you might be surprised by how easy it is to create a new user on Linux. To illustrate this, I'm going to walk you through the steps of adding a new user with both a GUI tool and from the command line interface (CLI). Both methods are simple and can be done by anyone with just about any skill level.

      • VituxHow to Install VMware Tools on Debian 11 - VITUX

        When you install a virtual machine or a guest OS on your machine, it does not exactly perform like the host OS because it has some limitations regarding performance. But VMware presented a solution for this by introducing VMware guest tools that enhance and improve the performance of the guest OS.

        VMware tools enable the integration between the host and the guest operating systems. It includes a set of utilities that improves the graphical performance of VM and enables sharing folders, clock synchronization, mouse tracking, and much more. Therefore, whenever you install a virtual machine on VMware, your first priority should be to install VMware tools before doing anything else.

        In this article, we will explain how to install VMware tools in Debian using two different methods.

      • VituxHow to View the Network Routing Table in Ubuntu Linux - VITUX

        Routing is the transfer of an IP packet from one point to another across the network. When you send someone an email, you’re actually transmitting a series of IP packets or datagrams from your system to the other person’s computer. The packets sent from your computer pass through several gateways or routers to get to the destination computer system. The same is true for all Internet protocols such as HTTP, IRC, FTP, etc.

        In all Linux and UNIX systems, the information about how the IP packets should be routed is stored in a kernel structure. These structures are called routing tables. If you want your system to communicate with other computers, you may want to configure these routing tables. First, it is important to know how to view these routing tables on your Linux system.

      • Drascula: Improving your Spanish language skills by playing an Adventure Game

        When testing the language support I noticed, that it has been originally developed by a company in Spain called Alcachofa Soft S.L., so additional to English it also includes speech in Spanish. Subtitles are available in English, German , French, Italian and Spanish. Therefore I decided to try improving my Spanish language skills and began to play this Adventure. And although the game is from 1996 I enjoyed it a lot!

        I figured out that if you press SPACE while a character is speaking, the sentence will be interrupted (apart from the voice part). And by pressing SPACE again the game continues. Which was rather useful for me in order to have more time for reading and understanding the subtitles.

      • Red Hat OfficialRethinking the path to modernizing application delivery

        Sir Isaac Newton once famously wrote, "If I have seen further, it is by standing upon the shoulders of giants."

        Most organizations recognize the benefits of modernizing application delivery, from accelerated time to value and improved client experience to reduced staff burden and increased talent retention. However, achieving these objectives at scale remains arguably one of the most daunting challenges to IT teams.

        Some organizations may find themselves lagging behind, debating where to begin as their environments continue to become more complex and their technical debt increases exponentially. Fortunately, Newton’s words highlight a silver lining: teams behind the curve have an advantage in that they’re able to learn from those who have come before them on the journey toward modernization.

        IT teams that run workloads on Ubuntu Linux have not one but two software package managers to work with: snap and apt.

        Although snap and apt both automate software package installation, management and removal, they work in different ways. An organization's choice between snap vs. apt depends on its IT priorities.

      • ArduinoLittleZone is a tribute to the 1980 video game Battlezone | Arduino Blog

        Back in 1980, the video game Battlezone was released, and it marked a major advancement in the world of computer graphics since it was the first game with a 3D first-person perspective. In it, the player must pilot a tank around a battlefield and fire at targets in an attempt to rack up the highest score possible. So as a way to commemorate the groundbreaking game, Mark Wilson created an approximation that runs on an Arduino Uno.

        Wilson has previous experience with vector graphics on embedded targets, as evidenced by his work on ElitePetite, an approximation of the loading screens from Acornsoft’s Elite game. Based on prior effort, he started the project by attempting to reverse engineer the original 6502 assembly and replicate its behavior. This process was a challenge owing to the complexity of the code, but after designing a clever sparse pixel encoding algorithm, the game could be completed, albeit with some minor graphical problems that appear when the game is being displayed on the attached 320×240 LCD screen.

      • Subscripts and Superscripts in Gemtext

        Building Gemipedia has taught me a lot about how to translate the various types of HTML formatting you find in Wikipedia content into Gemtext. Ignore things like italics or emphasis (you often don't need them). How do you represent math formulas?


        Many of the subscript and superscript letters come from different Unicode blocks, so there isn't a simple math function you can use to convert a typical letter into the subscript or superscript version, like you can easily compute the ASCII code of a lowercase letter from the ASCII code of the uppercase version. So the code to do the conversion is just a giant switch statement, that substitutes one character for another. You can see that in the "SuperscriptConverter.cs" and SubscriptConverter.cs" files in the Gemipedia source code...

      • bombadillo fork gets stdout capability

        A few days ago I got my bombadillo fork working with the Spartan protocol. Today I added the "-p" flag. This fetches the URL and prints the output to stdout.

        Por que?

        Well, I had managed to get Spartan working with a little Racket version I was working on. I found out about the Tinyblog format, and figured that it would be interesting. But I don't fancy trying to implement Gemini myself. The whole certificate thing looks a pain.

        I decided that a better approach would be to use bombadillo as a download agent. The plan is that it would output to a temporary file that Racket could then process. It seems easier.

      • Daniel StenbergNew HTTP core specs

        Before this, the latest refreshed specification of HTTP/1.1 was done in the RFC 7230 series, published in June 2014. After that, HTTP/2 was done in the spring of 2015 and recently the HTTP/3 spec has been a work in progress.

        To better reflect this new world of multiple HTTP versions and an HTTP protocol ecosystem that has some parts that are common for all versions and some other parts that are specific for each particular version, the team behind this refresh has been working on this updated series.

        • so wordpress uploads all content to their CDN servers – even when self hosted

          it “suddenly” and without consent it also exists on this server, the “cool” wordpress CDN, that is supposed to speed up loading time of a blog… well… not this blog eh?


          no – this blog is NOT using jetpack site accelerator.

          also the option described is not available on self hosted wordpress.


          wordpress – a giant content “sucking up ur content and storing it forever” machine?

          time for alternatives.

          if the visitor Firefox -> F12 -> network checks where the parts of this blog are coming from, they are all coming from and not some wordpress CDN for “faster loading time”.

          the only external content are the smileys:

          (those evil smileys probably “report back” to wordpress… how much that article was visited… and they (probably) sell it again… to G*** and M$ and whoever is willing to pay for that data)
