  • Three open-source giants to watch in 2021: Red Hat, SUSE, Ubuntu

    Apart from on desktop PCs used in businesses across the globe, the dominating operating systems on today’s computers are UNIX-like. The hardware that runs the world’s services, in the cloud, on the internet of things, and many phones, runs software that comprises of Linux variants and a small percentage of BSD-you-likes, typically FreeBSD. Windows Server instances still exist — estimates put the figure somewhere between 20% to 30% of servers running the OS.

    But in the main, the vast majority of operating systems, applications, databases, deployment tools, development tool-sets, and so forth comprise open-source software, which runs, usually, on UNIX-like operating systems.

    Of the Linux variants found in the data center, the three big players are Ubuntu Server (of Canonical), SUSE Linux Enterprise, and Red Hat Enterprise Linux — or variants thereon. (The word variants is often found in the free and open software world: variations or forks are rife in just about every part of open-source IT.)

  • Open-Source NVIDIA Support For Recent GPUs Is Poor But Now You Can Fake It For Testing

    The open-source NVIDIA "Nouveau" Gallium3D code within Mesa has wired up DRM shim support for basically faking the support in the absence of real hardware. This is mainly useful for testing the Nouveau OpenGL shader compiler code path without any actual code execution.

    Longtime Nouveau developer Ilia Mirkin wired up support for the Nouveau_Noop DRM shim. This basically allows the Nouveau Gallium3D code to function without submitting commands to any GPU or waiting on fences.

  • Parsing HID Unit Items

    This post explains how to parse the HID Unit Global Item as explained by the HID Specification, page 37. The table there is quite confusing and it took me a while to fully understand it (Benjamin Tissoires was really the one who cracked it). I couldn't find any better explanation online which means either I'm incredibly dense and everyone's figured it out or no-one has posted a better explanation. On the off-chance it's the latter [1], here are the instructions on how to parse this item.

    We know a HID Report Descriptor consists of a number of items that describe the content of each HID Report (read: an event from a device). These Items include things like Logical Minimum/Maximum for axis ranges, etc. A HID Unit item specifies the physical unit to apply. For example, a Report Descriptor may specify that X and Y axes are in mm which can be quite useful for all the obvious reasons.

    Like most HID items, a HID Unit Item consists of a one-byte item tag and 1, 2 or 4 byte payload. The Unit item in the Report Descriptor itself has the binary value 0110 01nn where the nn is either 1, 2, or 3 indicating 1, 2 or 4 bytes of payload, respectively. That's standard HID.

  • Opinion: What open-source software can teach big pharma

    At the Diamond Light Source synchrotron in Oxford, scientists shoot electrons through rings at near light speed to produce beams ten billion times brighter than the sun. These beams are used to study everything from painting fragments to viral structures. Last year researchers at Oxford University used the synchrotron, a large machine, to work out the molecular structure of COVID-19. Instead of selling off the discovery to the highest bidder, they put the information immediately into the open domain so that scientists globally could learn how COVID-19’s proteins infect the body.

    This sharing of information has been widely used by the software industry for decades. With open-source software, engineers share their source codes openly with their counterparts, who can then tinker with the codes and produce something new. Examples of open-source software products include the internet browser Mozilla Firefox and the Linux operating system. While this model has brought enormous benefits to the software industry, medicine has been slow to catch on.

    Matthew Todd, chair of drug discovery at University College London, likens open-source medicine to Wikipedia. All data and results are shared instantly and openly with the wider scientific community. This sharing of information could have real advantages for medicine because drugs are extremely expensive to research and most do not survive phase-one clinical trials. Rather than waste time experimenting with a molecule that a competitor has already proved to be unsafe, scientists could learn about failures instantly from a public data bank and then carry on experimenting with something new. Saving time and money by learning from others’ failures could lower drug prices and get new medicines to market sooner.

    New beginnings

    Some drug companies are beginning to experiment with open-source medicine. Pharma companies AbbVie, Bayer, and Johnson & Johnson have partnered with the Structural Genomics Consortium (SGC), a research organisation that studies less well-known areas of the human genome. The consortium is funded partly by drug companies and shares all of its findings openly with the public. Recently the SGC teamed up with the University of North Carolina Chapel Hill to have drugs ready for clinical trials when the next pandemic hits.

    Other drug companies are using the open-source model to help them begin researching rare diseases or illnesses that have high clinical failure rates. The associate director of global research at a pharmaceutical company says he has been given clear guidance to contact competitors and consortiums to develop shared risk models of innovation. The advantage, he says, is that by splitting the risk, more companies will be keen to invest their limited time and resources on less lucrative medicines.

  • 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.
