  • F2FS Picking Up "compress_cache" Feature With Linux 5.14 - Phoronix

    The Flash-Friendly File-System (F2FS) saw queued into its "dev" tree this week the new compress_cache mount option ahead of the upcoming Linux 5.14 cycle.

    Enabling the compress_cache mount option allows for using the address space of an inner inode to cache the compressed block. In turn doing so should improve the cache hit ratio for random reads with this flash-optimized file-system.

  • Profile Guided Optimizations (PGO) Likely Coming To Linux 5.14 For Clang - Phoronix

    Recently the mainline Linux kernel has seen a lot of improvements to its feature set when compiling it under LLVM's Clang rather than GCC as traditionally the only supported compiler. The most recent feature being brought to the Linux kernel when using Clang is finally allowing the use of compiler profile guided optimizations (PGO) for squeezing even greater performance out of the system by letting the compiler leverage the real-world profiles/metrics collected to make more informed code generation / optimization decisions.

    When Clang'ing the Linux kernel there has recently been support introduced for link-time optimizations (LTO) as another performance win. In turn this also allowed Clang Control Flow Integrity (CFI) support to also land in the mainline kernel. In the past there were patches to the Linux kernel to support GCC's LTO and PGO functionality but they hadn't been mainlined.

  • Transparent Hugepages Are Coming To RISC-V On Linux - Phoronix

    The Linux kernel's RISC-V support continues picking up remaining features not yet wired up beyond the base architecture support. The latest is transparent hugepages (THP) to be supported for RISC-V with Linux 5.14.

    Following recent RISC-V kernel additions like XIP for execute in place, support for KProbes and other features, and hardware specific work like SiFive FU740 SoC support, the latest RISC-V kernel action is transparent hugepages now being ready.

  • XFS To Enjoy Big Scalability Boost With Linux 5.14 - Phoronix

    A big patch series out of Red Hat is now queued into the XFS file-system development Git branch that is part of the new material for the upcoming Linux 5.14 cycle.

    The big set of patches that was queued this week into the xfs-5.14 for-next code focuses on CIL (Committed Item List) and log scalability improvements.

    There are good performance numbers being seen out of this scalability work for the XFS file-system. The big numbers are seeing the transaction rate go up from around 700k to 1.7M commits per second and a reduction in flush operations by 2~x orders of magnitude less for metadata heavy workloads that don't enforce fsync.

  • NVIDIA Confirms Plans To Drop "Kepler" GPU Driver Support - Phoronix

    Last month we reported on CUDA documentation pointing to the NVIDIA 470 driver series to be the last supporting GeForce GTX 600/700 Kepler GPUs and that has now been summed up more formally with new guidance out of NVIDIA.

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.
