  • IO500 List Showcases World’s Fastest Storage Systems for HPC

    In this video from ISC 2018, John Bent and Jay Lofstead describe how the IO500 benchmark measures storage performance in HPC environments. The second IO500 list was revealed at ISC 2018 in Frankfurt, Germany.

    [...]

    Specifically, the benchmark suite includes a hero-run of both IOR and mdtest configured however possible to maximize performance and establish an upper-bound for performance. It also includes an IOR and mdtest run with highly prescribed parameters in an attempt to determine a lower-bound. Finally, it includes a namespace search as this has been determined to be a highly sought-after feature in HPC storage systems that has historically not been well-measured. Submitters are encouraged to share their tuning insights for publication.

  • Cooking with Linux (without a Net): Backups in Linux, LuckyBackup, gNewSense and PonyOS

    It's Tuesday, and it's time for Cooking with Linux (without a Net) where I do some live Linuxy and open-source stuff, live, on camera, and without the benefit of post-video editing—therefore providing a high probability of falling flat on my face. And now, the classic question: What shall I cover? Today, I'm going to look at backing up your data using the command line and a graphical front end. I'm also going to look at the free-iest and open-iest distribution ever. And, I'm also going to check out a horse-based operating system that is open source but supposedly not Linux. Hmm...

  • Why it's not a good idea to handle evdev directly

    Gather round children, it's story time. Especially for you children who lurk on /r/linux and think you may learn something there. Today, I'll tell you a horror story. The one where we convert kernel input events into touchpad events, with the subtle subtitle of "friends don't let friends handle evdev events".

    The question put forward is "why do we need libinput at all", when, as frequently suggested on the usual websites, it's sufficient to just read evdev data and there's really no need for libinput. That is of course true. You can use evdev events from the kernel directly. Did you know that the events the kernel gives you are absolute coordinates? And that not all touchpads have buttons? Or that some touchpads have specific event sequences that need to be filtered? No? Well, boy, are you in for a few surprises! Anyway, let's go and handle evdev events ourselves and write our own libmyinput.

  • 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.
