  • CISA Releases Cloud Security Technical Reference Architecture [Ed: This is absurd because "the clown" means a security breach, unless it's the government itself running and controlling that "clown computing"]

    CISA has released its Cloud Security (CS) Technical Reference Architecture (TRA) to guide federal civilian departments and agencies in securely migrating to the cloud.

  • This project lets you experience life with a cybernetic tail | Arduino Blog

    Modern humans have forgone their tails in favor of walking upright, and this fact left maker Pengfei Zhang wondering what it would be like to have such an appendage. From this idea, she along with Sarvenaz Sardari and Xi Peng created the Cyber Tail, which integrates embedded electronics into a small device that moves with its wearer.

    The Cyber Tail’s design revolves around a central base that houses a set of four servo motors. In order to move the tail in various directions, each servo motor can either pull or release a single string, which causes the tail itself to bend, akin to how a finger works except in four possible directions. The Arduino Uno controlling these motions relies on an external IR sensor within a pair of glasses that detects whenever the user blinks.

  • Current status of LightDM

    LightDM is a cross-desktop display manager that was developed by Canonical. It was used as the default display manager in Ubuntu from 11.10 to 17.04 after which it was replaced with GDM. It continues to be part of Ubuntu and other distributions and is used by the smaller desktops as a display manager.

    Since it was no longer the default display manager in Ubuntu development resources have reduced, but it continues to work. There is some bit rot that has occurred as things change around it.

    All development is done in GitHub. You are welcome to file issues and pull requests there. Discussion is done here on discourse.ubuntu.com. Note that even though this is the Ubuntu discourse, LightDM is still expected to work on other distributions and this is not an indication that this project only relates to Ubuntu.

    LightDM used to follow a release cycle that matches the Ubuntu release cycle. Currently no releases are being made, you can either use the most recent release or use the main git branch. The main branch should always be usable.

  • Programming in blocks lets far more people code — but not like software engineers: Response to the Ofsted Report

    I completely agree with the first sentence — there are benefits to using block-based programming in terms of reducing the need to memorize syntax and increasing usability. There is also evidence that secondary school students learn computing better in block-based programming than in text-based programming (see blog post). Blanchard, Gardner-McCune, and Anthony found (a Best Paper awardee from SIGCSE 2020) that university students learned better when they used both blocks and text than when they used blocks alone.

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. 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 MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
