Leftovers: Software

  • Nginx 1.12 Released
  • Docker Enterprise Edition Arrives to Help Monetize Open-Source Docker

    Making money from open-source software is not exactly a straightforward proposition, but the poster child for businesses based on open-source code is Red Hat.

    The so-called "Red Hat model" involves charging customers a subscription for a business-ready version of its open-source Linux distribution. This gets customers a certified and maintained release with regular updates and security fixes.

  • Singularity Containers for HPC, Reproducibility, and Mobility

    Containers are an extremely mobile, safe and reproducible computing infrastructure that is now ready for production HPC computing. In particular, the freely available Singularity container framework has been designed specifically for HPC computing. The barrier to entry is low and the software is free.

    At the recent Intel HPC Developer Conference, Gregory Kurtzer (Singularity project lead and LBNL staff member) and Krishna Muriki (Computer Systems Engineer at LBNL) provided a beginning and advanced tutorial on Singularity. One of Kurtzer’s key takeaways: “setting up workflows in under a day is commonplace with Singularity”.

  • Cloud Commander – Web File Manager to Control Linux File and Programs via Browser

    Cloud Commander (cloudcmd) is a simple open source, traditional yet useful cross-platform web file manager with console and editor support.

    It is written in JavaScript/Node.js and enables you manage a server and work with files, directories and programs in a browser from any computer, mobile or tablet.

  • Nylas Mail Client Now Available on Linux

    A Linux version of Nylas Mail, the cross-plaform desktop e-mail client, is available for testing. The open-source app succeeds the old Nylas N1 client, which was discontinued last year. Since we last mentioned the app back in January a few things have changed.

  • Blender 2.79 Is Bringing Performance Improvements, Better OpenCL

    Blender 2.79 is under development and it sounds like this release should be quite exciting for those into performance improvements or better OpenCL support.

    With Blender 2.79, the OpenCL support has improved and should be closer to parity with Blender's CUDA capabilities. The OpenCL Cycles renderer has shorter render times by up to 50% in some cases, tiles are now seen updating while rendering, support for SSS and volume rendering, optimized transparent shadows, and various fixes.

  • GNOME Music: the road to 3.24

    GNOME Music 3.24.1.1 has just been released, a good time to reflect on what has happened last development cycle.

    A goal for Music is to make it an exemplary application of GNOME/GTK+ Python programming and make it an entry-level project for new contributors. However the codebase was a mixture of coding styles and oversized multi-functional classes. Python is a powerful and easily accessible language, but the downside is that it can quickly get out of control if not some constraints are set on how to use it. So we started a rework to split up some of the bigger source files and enforce PEP-8 (code-style) & PEP-257 (docstrings) on new commits and bring existing code in line with it. We are not quite there yet on the clean-up front, but we have come a long way and going forward it is gonna get better.

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.
