  • Some things to reduce background bandwidth usage on a Fedora machine

    Suppose, not entirely hypothetically, that you have a Fedora laptop and you want it to use minimal bandwidth for things that you don't specifically do. Unfortunately there are only a few things that I know of to do, and I'm not sure they're comprehensive. Most of my information comes from this old r/Fedora post.

  • First POWER10 Machine Announced

    IBM turns up the volume to 10 (and their server numbers to four digits) with the Power E1080 server, the launch system for POWER10. POWER10 is a 7nm chip fabbed by Samsung with up to 15 SMT-8 cores (a 16th core is disabled for yield) for up to 120 threads per chip. IBM bills POWER10 as having 2.5 times more performance per core than Intel Xeon Platinum (based on an HPE Superdome system running Xeon Platinum 8380H parts), 2.5 times the AES crypto performance per core of POWER9 (no doubt due to quadruple the crypto engines present), five times "AI inferencing per socket" (whatever that means) over Power E980 via the POWER10's matrix math and AI accelerators, and 33% less power usage than the E980 for the same workload. AIX, Linux and IBM i are all supported.

  • Russ Allbery: Pod::Thread 3.00

    This Perl module converts POD documents to thread, the macro language I use for my static site builder (about which, more in another software release coming up shortly). This release fixes a whole ton of long-standing problems.

  • Fscrypt broken in user spot

    It turns out that there is a fundamental problem in EasyOS. If a person entered a password at the very first bootup, Easy creates encrypted folders in the ext4 working-partition. So, if anyone steals your usb-stick or hard drive, they won't be able to access the files in those folders.

    The encryption mechanism works on a per-folder basis, and the init script in the initrd will unlock those folders when the correct password is entered at bootup. It works great, however, falls apart if login as a non-root user...

    I have a utility, 'keyctl', from the 'keyutils' package. I have today compiled that in OE and added it to the package list, so it will be in future releases of EasyOS. It is for managing the kernel keys. I know hardly anything about this topic, but let's explore...

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.
