  • Daniel Stenberg: Expect: tweaks in curl

    One of the persistent myths about HTTP is that it is “a simple protocol”.

    [...]

    Background

    HTTP/1.1 is designed for being sent over TCP (and possibly also TLS) in a serial manner. Setting up a new connection is costly, both in terms of CPU but especially in time – requiring a number of round-trips. (I’ll detail further down how HTTP/2 fixes all these issues in a much better way.)

    HTTP/1.1 provides a number of ways to allow it to perform all its duties without having to shut down the connection. One such an example is the ability to tell a client early on that it needs to provide authentication credentials before the clients sends of a large payload. In order to maintain the TCP connection, a client can’t stop sending a HTTP payload prematurely! When the request body has started to get transmitted, the only way to stop it before the end of data is to cut off the connection and create a new one – wasting time and CPU…

    “We want a 100 to continue”

    A client can include a header in its outgoing request to ask the server to first acknowledge that everything is fine and that it can continue to send the “payload” – or it can return status codes that informs the client that there are other things it needs to fulfill in order to have the request succeed. Most such cases typically that involves authentication.

  • Environmental activist Shannon Dosemagen joins FSF conference keynote lineup

    Shannon Dosemagen is the second confirmed keynote speaker for the LibrePlanet conference. Dosemagen is the co-founder and current executive director of Public Lab, a nonprofit organization creating local environmental science solutions following the free software philosophy, and winner of the FSF's Award for Projects of Social Benefit. Shannon Dosemagen is an environmental health advocate and a community science champion, and is enthusiastic about free systems and technology that support the creation of a more just and equitable future. She is a previous Fellow at both the Harvard Berkman Klein Center for Internet and Society, and the Loyola University Environmental Communications Institute. During 2020, she will be a Fellow with the Shuttleworth Foundation, working on new concept.

    At LibrePlanet, Dosemagen will discuss her experience democratizing science to address environmental problem-solving. Her experiences and frustrations doing this work are very familiar to the free software community: "The work I do on the environment and health is being increasingly challenged by environmental deregulation and lack of cooperation. We're also seeing heightened pressure to drastically alter how society functions in an effort to curb the climate crisis. This is a profound moment, and critical to address at an event aptly themed 'Free the Future.'"

    "Shannon's work is very important, and is a testament to the success of community collaboration," says Zoë Kooyman, the FSF's program manager. "Public Lab's work towards free hardware solutions is a strong indicator of what the four freedoms can achieve, and how they can work towards a better future outside of software. Shannon is an experienced speaker and organizer, and we are proud to have her keynote at LibrePlanet."

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.
