  • Christian Kastner: Keeping your Workstation Silent

    I've tried numerous coolers in the past, some of monstrous proportions (always thinking that more mass must be better, and reputable brands are equally good), but I was never really satisfied; hence, I was doubtful that trying yet another cooler would make a difference. I'm glad I tried the Noctua NH-D15 anyway. With some tweaking to the fan profile in the BIOS, it's totally inaudible at normal to medium workloads, and just a very gentle hum at full load—subtle enough to disappear in the background.

    For the past decade, I've also regularly purchased sound-proofed cases, but this habit appears anachronistic now. Years ago, sound-proofed cases helped contain the noise of a few HDDs. However, all of my boxes now contain NVMe drives (which, to me, are the biggest improvement to computing since CPUs going multi-core).

    On the other hand, some of my boxes now contain powerful GPUs used for GPGPU computing, and with the recent higher-end Nvidia and AMD cards all pulling in over 300W, there is a lot of heat to manage. The best way to quickly dump heat is with good airflow. Sound-proofing works against that. Its insulation restricts airflow, which ultimately causes even more noise, as the GPU's fans need to spin at very high RPMs. This is, of course, totally obvious in hindsight.

  • Junichi Uekawa: It's been 20 years since I became a Debian Developer.

    It's been 20 years since I became a Debian Developer. Lots of fun things happened, and I think fondly of the team. I am no longer active for the past 10 years due to family reasons, and it's surprising that I have been inactive for that long. I still use Debian, and I still participate in the local Debian meetings.

  • Michael Prokop: Revisiting 2020

    Mainly to recall what happened last year and to give thoughts and plan for the upcoming year(s) I’m once again revisiting my previous year (previous editions: 2019, 2018, 2017, 2016, 2015, 2014, 2013 + 2012).

    Due to the Coronavirus disease (COVID-19) pandemic, 2020 was special™ for several reasons, but overall I consider myself and my family privileged and am very grateful for that.

    In terms of IT events, I planned to attend Grazer Linuxdays and DebConf in Haifa/Israel. Sadly Grazer Linuxdays didn’t take place at all, and DebConf took place online instead (which I didn’t really participate in for several reasons). I took part in the well organized DENOG12 + ATNOG 2020/1 online meetings. I still organize our monthly Security Treff Graz (STG) meetups, and for half of the year, those meetings took place online (which worked OK-ish overall IMO).

    Only at the beginning of 2020, I managed to play Badminton (still playing in the highest available training class (in german: “Kader”) at the University of Graz / Universitäts-Sportinstitut, USI). For the rest of the year – except for ~2 weeks in October or so – the sessions couldn’t occur.

    Plenty of concerts I planned to attend were cancelled for obvious reasons, including the ones I would have played myself. But I managed to attend Jazz Redoute 2020 – Dom im Berg, Martin Grubinger in Musikverein Graz and Emiliano Sampaio’s Mega Mereneu Project at WIST Moserhofgasse (all before the corona situation kicked in). The concert from Tonč Feinig & RTV Slovenia Big Band occurred under strict regulations in Summer. At the beginning of 2020, I also visited Literaturshow “Roboter mit Senf” at Literaturhaus Graz.

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.
