  • Essential should open source its accessories platform

    With all these shortcomings, the company has struggled under the father of Android, Andy Rubin. Sales estimations of the PH-1 have come in well below 200,000 units. Subsequently, the rumors have been rampant that the company is up for sale to get out from under its debts. Another struggle has been its proprietary accessory system. That’s the topic I’d like to take on in this post. Essential should open source its plans for mods.

  • 3D-Printed Firearms Are Blowing Up

    If you follow 3D printing at all, and even if you don't, you've likely seen some of the recent controversy surrounding Defense Distributed and its 3D-printed firearm designs. If you haven't, here's a brief summary: Defense Distributed has created 3D firearm models and initially published them for free on its DEFCAD website a number of years ago. Some of those 3D models were designed to be printed with a traditional home hobbyist 3D printer (at least in theory), and other designs were for Defense Distributed's "Ghost Gunner"—a computer-controlled CNC mill aimed at milling firearm parts out of metal stock. The controversy that ensued was tied up in the general public debate about firearms, but in particular, a few models got the most attention: a model of an AR-15 lower receiver (the part of the rifle that carries the serial number) and "the Liberator", which was a fully 3D-printed handgun designed to fire a single bullet. The end result was that the DEFCAD site was forced to go offline (but as with all website take-downs, it was mirrored a million times first), and Defense Distributed has since been fighting the order in court.

    The political issues raised in this debate are complicated, controversial and have very little to do with Linux outside the "information wants to be free" ethos in the community, so I leave those debates for the many other articles on this issue that already have been published. Instead, in this article, I want to use my background as a hobbyist 3D printer and combine it with my background in security to build a basic risk assessment that cuts through a lot of the hype and political arguments on all sides. I want to consider the real, practical risks with the 3D models and the current Ghost Gunner CNC mill that Defense Distributed provides today. I focus my risk assessment on three main items: the 3D-printed AR-15 lower receiver, the Liberator 3D-printed handgun and the Ghost Gunner CNC mill.

  • 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.
