  • Linux's USB Audio Driver Aims For Latency Reduction - Phoronix

    With the upcoming Linux 5.14 cycle, the USB sound driver will ideally exhibit lower latency when starting playback.

    Longtime Linux kernel sound subsystem maintainer Takashi Iwai of SUSE has been working on a clean-up to the kernel's USB-Audio driver and with an emphasis on latency reduction during audio playback.

  • Linux Plumbers Conference: Performance and Scalability Microconference Accepted into 2021 Linux Plumbers Conference

    We are pleased to announce that the Performance and Scalability Microconference has been accepted into the 2021 Linux Plumbers Conference.

    All parts of the Linux ecosystem, kernel and userspace, should account for performance and scalability. The purpose of this microconference is for developers from different projects to meet and collaborate, as the entire stack must perform well for the user to see good results. Because performance and scalability are very generic topics, this microconference focuses on issues that may also be addressed in other, more specific sessions.

    The structure will be similar to what was followed in previous years, including topics such as synchronization primitives, bottlenecks in memory management, testing/validation, lockless algorithms and RCU, among others.

    Going back over a year has been the proposed FUTEX2 system call to extend FUTEX, which for a year prior to to going for a new/separate system call had been aiming to optimize FUTEX for enhancing the Linux gaming experience by better matching the behavior of Windows -- in particular, around Windows NT allowing to wait on multiple objects.

  • 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.
