  • When will we learn?

    Congratulations to Rust for its first (but not its last) supply-chain attack this week! They join a growing club of broken-by-design package managers which publish packages uploaded by vendors directly, with no review step, and ship those packages directly to users with no further scrutiny.

  • Improved Process Isolation in Firefox 100 - Mozilla Hacks - the Web developer blog

    Firefox uses a multi-process model for additional security and stability while browsing: Web Content (such as HTML/CSS and Javascript) is rendered in separate processes that are isolated from the rest of the operating system and managed by a privileged parent process. This way, the amount of control gained by an attacker that exploits a bug in a content process is limited.

    Ever since we deployed this model, we have been working on improving the isolation of the content processes to further limit the attack surface. This is a challenging task since content processes need access to some operating system APIs to properly function: for example, they still need to be able to talk to the parent process.

    In this article, we would like to dive a bit further into the latest major milestone we have reached: Win32k Lockdown, which greatly reduces the capabilities of the content process when running on Windows. Together with two major earlier efforts (Fission and RLBox) that shipped before, this completes a sequence of large leaps forward that will significantly improve Firefox’s security.

    Although Win32k Lockdown is a Windows-specific technique, it became possible because of a significant re-architecting of the Firefox security boundaries that Mozilla has been working on for around four years, which allowed similar security advances to be made on other operating systems.

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.
