  • Install Docker and Portainer - blackMORE Ops

    Docker is a set of platform as a service (PaaS) products that use OS-level virtualization to deliver software in packages called containers. Containers are isolated from one another and bundle their own software, libraries and configuration files; they can communicate with each other through well-defined channels. Because all of the containers share the services of a single operating system kernel, they use fewer resources than virtual machines. The service has both free and premium tiers. The software that hosts the containers is called Docker Engine.

    Portainer CE is a lightweight ‘universal’ management GUI that can be used to easily manage Docker, Swarm, Kubernetes and ACI environments. It is designed to be as simple to deploy as it is to use. Portainer consists of a single container that can run on any cluster. It can be deployed as a Linux container or a Windows native container. Portainer allows you to manage all your orchestrator resources (containers, images, volumes, networks and more) through a super-simple graphical interface. A fully supported version of Portainer is available for business use.

  • Record your terminal with script and scriptreplay

    A fascinating thing about humans is that we each have a particular learning style. Some people prefer to read about how something's done. Some people prefer to follow instructions from the start, while others prefer to get an overview before engaging. Other people like to listen to instructions from an instructor or a podcast. And yet another group wants instructions in the form of a video. The trouble with video is that it can be difficult to produce and compress, and it is a lot of work to change once it's done. And besides that, viewers can't copy and paste Linux commands out of a video into their terminal. [...] The script and scriptreplay commands allow you to record a terminal session and then play it back later. There's no video involved. Instead, plain text files called typescripts are used, so the files are small and users can copy commands during playback.

  • How to install FirewallD GUI on Rocky Linux 8 | Almalinux 8 - Linux Shout

    Here in this article, we learned the simple steps and commands to install a graphical user interface (GUI) to manage FirewallD on either Alamlinux or Rocky Linux 8. However, the steps are the same for CentOS, Redhat, Oracle Linux, and other RPM-based distros. FirewallD is a command-line tool to provide a system firewall feature to protect Linux unwanted access by disabling and enabling ports and services access to outside or local networks. However, if you are using a Graphical interface user then the command line may seem a little bit difficult to use. Therefore, to make things easy we can use GUI tools available to manage FirewallD such as one from firewall-config or Plasma firewall

  • AutoStrap is a self-tightening strap that's like something out of Back to the Future | Arduino Blog

    For wearable devices, attaching them to an arm or leg can be an annoying process since the straps used often have complicated tightening/locking mechanisms. This is what inspired one Instructables user who goes by The Puma to create the AutoStrap, a self-tightening strap system for wearable electronics similar to Marty McFly’s power-lacing shoes in Back to the Future.

  • Arduino Week 2022: Call for speakers | Arduino Blog

  • Plot designs onto cups with CylinDraw | Arduino Blog

    Most plotters are planar, meaning they move in a single plane — though they often have the ability to move the tool up and down in the third axis. But if you convert one axis of the drawing plane into rotation, you get cylindrical plotting. That is how the rotary axis on a CNC machine works. If the tool moves in a third axis, you can even do conical plots. That’s exactly how CylinDraw makes it possible to plot directly onto cups and glasses. CylinDraw is an open source “cup-specific” plotter and engraver. It is a 2.5 axis machine with a rotary axis, similar to the famous EggBot egg plotter. Except instead of drawing onto the elliptical (in cross section) surface of an egg, CylinDraw plots onto the straight or sloped surface of cups, bottles, and similar objects. By equipping a Dremel or other rotary tool, you can also engrave onto a surface instead of drawing. If you do draw, the software also lets you swap pens to get a full color palette.

  • I2C To The Max With ATtiny | Hackaday

    The Arudino is a powerful platform for interfacing with the real world, but it isn’t without limits. One of those hard limits, even for the Arduino MEGA, is a finite number of pins that the microcontroller can use to interface with the real world. If you’re looking to extend the platform’s reach in one of your own projects, though, there are a couple of options available. This project from [Bill] shows us one of those options by using the ATtiny85 to offload some of an Arduino’s tasks using I2C.

Games: Counter-Strike: Global Offensive, Penguin Heist, and More

  • Counter-Strike: Global Offensive updated, more tweaking for Steam Deck + Vulkan | GamingOnLinux

    Valve continues to tweak more of their games ahead of the Steam Deck release in February and their focus now appears to be on CS:GO with a fresh update out. A few more Steam Input improvements came for controllers, with their newer "FlickStick" mode enabled in the game options instead of the Steam Input Configurator and there's also refinements to the behaviour. For those not aware, FlickStick created by Jibb Smart is in essence a quick way to turn to face any direction in a game, allowing you to be more accurate and speedy with gamepad sticks. Valve added support for it to Steam Input directly in 2021, now it has better native support in CS:GO.
