  • How to Configure Static IP Address on Fedora Linux

    Hi techies, as we know Fedora is one of popular open source Linux based operating system. Fedora Linux can be used as workstation, Server, and CoreOS.

    In this guide, we learn how to manually configure static ip address on Fedora Linux (Fedora 36 Workstation). A static IP address is an IP address that stays the same over time and remain persistent across the reboot. There are two different ways to configure static IP.

  • Write HTML Right

    I hope I've persuaded you to write good HTML from now on. Failing that, I hope I've at least expressed myself well enough to get you thinking about it. You can view the source of this document to see how these principles play out (or don't!) in practice.

  • Text consoles and framebuffer consoles in Linux

    For a long time, the Linux kernel text console on x86 hardware used VGA text mode (also). The important thing about VGA text mode is that what the kernel wrote into display memory in order to show things was not pixels but characters (okay, 8-bit codepoints). The actual text buffer used two bytes in order to add colour and attributes, but that's only a small change. The important thing is that manipulating an 80x25 buffer of 16-bit objects is quite fast. Completely repainting the entire screen requires writing only 4,000 bytes.

  • Best practices for inclusive CLIs

    This began as a reply to another article by Lucas F. Costa; it lists practices to improve user-experience (UX) of command-line interfaces (CLIs). It comes from a good place, and has some good advice: I particularly like its advice on input-validation and understandable errors. Unfortunately, a number of its suggestions are problematic, particularly from an accessibility perspective.

  • Matrix Synapse: migrating from Cloudron to ansible

    Maybe, like me, you tried to selfhost a Matrix Synapse server, miserably failed because it's just not quite that easy and then settled for Cloudron's Synapse app because it just works. Pay a bit more, worry a little less.

    Sure, it works but you still introduced a middle man in your pristine homelab setup and the itch never goes away to get rid of it.

    Time for round 2.

  • How to Get Started Using the Docker Engine API

    Docker Engine exposes a REST API which you can use to control your containers without the docker CLI. The API exposes equivalent functionality using HTTP network calls. You can script common Docker operations using your favorite programming language or remotely control one of your hosts. The CLI internally relies on the same API to provide its built-in commands.

  • 11 Ways To Create a File in Linux - ByteXD

    Learning to create a file in Linux using many ways is a recommendable step toward speeding up the use of the operating system.

  • [Old] Personal Streaming Audio Server

    For a while now, I’ve been looking for a good way to stream music from my home music collection on my phone.

    There are quite a few options for music servers that support streaming. However, Android apps that can stream music from one of those servers tend to be unmaintained, clunky or slow (or more than one of those).

    It is possible to use something that runs in a web server, but that means no offline caching - which can be quite convenient in spots without connectivity, such as the Underground or other random bits of London with poor cell coverage.

  • PoC: Cobalt Strike mitm Attack

    I made a small Proof-of-Concept: cs-mitm.py is a mitmproxy script that intercepts Cobalt Strike traffic, decrypts it and injects its own commands.

  • Linux DD Command – 18 Examples with All Options

  • 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.
