  • Linux 5.7 Netfilter To See AVX2 Optimizations For Big Performance Boost - Can Be Up To ~420%

    Linux 5.7's Netfilter framework is set to see better performance on modern Intel and AMD systems thanks to AVX2 optimizations. 

    Queued on Sunday in nf-next as the Netfilter staging grounds are AVX2 optimizations to provide great speed benefits. 

    Red Hat's Stefano Brivio has provided an AVX2-optimized nft_set_pipapo implementation. AVX2 works out well for optimizing the packet lookup routines of the Netfilter Pile Packet Policies. 

  • AMD Sensor Fusion Hub Driver Isn't Yet Queued For Linux 5.7

    While a lot of feature work has been building up for Linux 5.7 in various subsystem development repositories ahead of the merge window in a few weeks, one of the big driver additions many users have been clamoring for isn't yet queued. The AMD Sensor Fusion Hub open-source driver for Linux appears stalled pending more reviews from upstream developers. 

    Back in January AMD published the long awaited Sensor Fusion Hub support for Linux that AMD Linux laptop customers have been after since 2018. The Sensor Fusion Hub (SFH) driver is needed for supporting various laptop sensors like the accelerometer and gyroscope. The amd-sfh-hid driver is similar to Intel's Sensor Hub that has seen Linux support from the start for supporting the sensors on various Intel-powered laptops. 

  • 7 Linux Distros for Security Testing

    Linux is often talked about when it comes to security. With this OS, you can choose from a multitude of distributions (distros) to lock down your computer or device, but that’s just for starters. Many Linux distros come with tools to help you perform penetration tests and security audits.

    The following article lists just a few Linux distros for security testing. Many are based on Debian or Ubuntu with some added built-in custom tools.

  • 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.
