  • Install FreeRADIUS & daloRADIUS on Debian 10/11 + MySQL/MariaDB - ByteXD

    FreeRADIUS is the most widely-deployed, open-source, and free RADIUS implementation. It works as a daemon (operates in the background) in Unix and Unix-like servers. FreeRADIUS is used mainly for

    The RADIUS protocol allows you to authenticate users over a network, authorize them for various actions, and monitor their usage of the network. This framework is referred to as AAA (Authentication, Authorization, and Accounting).

    According to a survey result, FreeRADIUS is used to authenticate over one-thirds of the users on the internet.

    By default, FreeRADIUS has a command line interface, and any changes are made by editing the configuration files that are highly customizable. Since it’s open-source, you can even make changes in the code of the software.

    In this article, we will discuss how to install FreeRADIUS and daloRADIUS on Debian 10.

  • How to flash firmware to Rockchip devices in Windows and Linux (2021 Edition) - CNX Software

    But following my review of Zidoo M6 with Android 11, I’ve now got a Linux image for the Rockchip RK3566 mini PC, so let’s revisit the firmware flashing methods in 2021. Zidoo sent me instructions for Windows, but since I’m a Ubuntu user, I flashed the firmware with the Linux tools used by Firefly. The same methods should work for the older processors such as RK3066, RK3288, and RK3399, besides the more recent Rockchip RK3566 and RK3568 processors.

  • Changing the Output in Assembly | Adam Young’s Web Log

    When ever I write new console based code from scratch, I start with “Hello World.” Then I make one small change at a time, test it, and commit. Then I move on. While this slow process might seem tedious, it is based on years of wasting time debugging my own poorly written code in interim changes.

    Once I had “Hello, World!” working in assembly, I want to make a single character change to message and see it in the console. Here’s my steps.

    Let’s start with “Hello, World.” I got this out of Programming with 64-Bit ARM Assembly Language. The team there gets extra Kudos for using Git to put the book together in a public fashion.

  • How To Install Squid Proxy on AlmaLinux 8 - idroot

    In this tutorial, we will show you how to install Squid Proxy on AlmaLinux 8. For those of you who didn’t know, Squid Proxy is an open source caching proxy for the web. It supports many protocols such as HTTP, HTTPS, FTP and more. By caching and reusing frequently-requested web pages, squid saves bandwidth and improves response time making accessing web pages very fast.

    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 through the step-by-step installation of the Squid Proxy server on an AlmaLinux 8. You can follow the same instructions for CentOS and Rocky Linux.

  • Running Assembly Code Through the debugger | Adam Young’s Web Log

    There are two basic ways to inspect a running program: print out a bunch of debug statements or run it through a debugger. Since I don’t yet know how to print out my own statements in ARM64 debugging (I’ll get there soon) I want to use the debugger to see my code in action.

    First, a little tweak to the Makefile rule to build the code. I hard code in the -g flag to include debugging symbols in the executables. This is learning code, and I am not going to be running it in stripped mode, so no need for Makefile variables.

  • Simplest Assembly Program that Runs without an error | Adam Young’s Web Log

    In order for a program to run successfully, it needs two things: an entry symbol, and a return code that represents that success. The following program provides those two things.

  • Simple Makefile for assembly executables | Adam Young’s Web Log

    I want to automatically build assembly files into executable binaries. The following Makefile seems to be sufficient. I am sure I will add to it over time.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • 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.
