  • Pitivi applies to the Season of Docs

    The Pitivi video editor is based on the GStreamer Editing Services library (GES). Various projects use GES to manage audio or video projects and export the project to a new file to be distributed.

    Pitivi is developed in very close contact with GES. Both Pitivi and GES would benefit a lot from better documentation.

    We’re applying to the Season of Docs program, where Google pays technical writers to contribute to open-source projects. Check out the technical writer guide for details and the program timeline. Read below the project ideas if you are interested in working with us!

  • arm64 on apt.postgresql.org

    The apt.postgresql.org repository has been extended to cover the arm64 architecture.

    We had occasionally received user request to add "arm" in the past, but it was never really clear which kind of "arm" made sense to target for PostgreSQL. In terms of Debian architectures, there's (at least) armel, armhf, and arm64. Furthermore, Raspberry Pis are very popular (and indeed what most users seems to were asking about), but the raspbian "armhf" port is incompatible with the Debian "armhf" port.

    Now that most hardware has moved to 64-bit, it was becoming clear that "arm64" was the way to go. Amit Khandekar made it happen that HUAWEI Cloud Services donated a arm64 build host with enough resources to build the arm64 packages at the same speed as the existing amd64, i386, and ppc64el architectures. A few days later, all the build jobs were done, including passing all test-suites. Very few arm-specific issues were encountered which makes me confident that arm64 is a solid architecture to run PostgreSQL on.

  • The Month in WordPress: April 2020

  • In The Age Of Coronavirus, How Doctors Are Becoming Inventors

    The last time anesthesiologist James Nilson went backpacking, he probably didn’t expect to be using a camping technique later in the operating room.

    “I've been living in the woods, backpacking and hiking my entire life. So, you know, there's a lot of adaptations that you make when you're out in the woods that call upon your ability to just be a little bit creative. And that seems to be holding pretty true in a career as an anesthesiologist as well,” he said.

  • Hot On The Heels Of Mellanox, Nvidia Snaps Up Cumulus Networks

    Last week, when we talked to Nvidia co-founder and chief executive officer, Jensen Huang, about how the datacenter was becoming the unit of compute and in such a world networking was critical, it was obvious that acquiring Mellanox Technologies for $6.9 billion was just the beginning of the strategy that will no doubt unfold in the coming months and years.

    Huang didn’t wait long to make another move, with Nvidia acquiring open network software provider Cumulus Networks for an undisclosed sum and marrying it with Mellanox in its newly formed networking business unit.

    Sometimes, to understand what a company is doing you have to take a really hard look at the things that key people at that company have seen and done in their careers. This is one of those cases.

  • 6 Kubernetes Prometheus Alternatives

Riding a Cloud: NVIDIA Acquires Network-Software Trailblazer

  • Riding a Cloud: NVIDIA Acquires Network-Software Trailblazer Cumulus

    Cloud data centers are evolving to an architecture that is accelerated, disaggregated and software-defined to meet the exponential growth in AI and high performance computing. To build these modern data centers, HPC and networking hardware and software must go hand in hand.

    NVIDIA provides the leading accelerated computing platform. Mellanox is the high-performance networking leader, now part of NVIDIA in a combination described in our founder and CEO’s welcome letter.

    Today we announce our plan to acquire Cumulus Networks, bolstering our networking software capabilities. The combination enables the new era of the accelerated, software-defined data center.

    With Cumulus, NVIDIA can innovate and optimize across the entire networking stack from chips and systems to software including analytics like Cumulus NetQ, delivering great performance and value to customers. This open networking platform is extensible and allows enterprise and cloud-scale data centers full control over their operations.

  • Nvidia makes Linux push with Cumulus Networks deal

    Nvidia has announced its plans to acquire the open-source centric company Cumulus Networks which specializes in helping enterprise businesses optimize their data center networking stacks.

    Cumulus Networks also offers its own Linux distribution for network switches, its own data center switch with Cumulus Express and tools for managing network operations.

    Although both companies have yet to reveal the price of the acquisition, it will likely be quite high as Cumulus Networks has raised $134m since its founding back in 2010, according to CrunchBase.

  • 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.
