  • Saving birds with technology

    Two members of the Cacophony Project came to linux.conf.au 2019 to give an overview of what the project is doing to increase the amount of bird life in New Zealand. The idea is to use computer vision and machine learning to identify and eventually eliminate predators in order to help bird populations; one measure of success will be the volume and variety of bird song throughout the islands. The endemic avian species in New Zealand evolved without the presence of predatory mammals, so many of them have been decimated by the predation of birds and their eggs. The Cacophony Project is looking at ways to reverse that.

  • Mozilla's initiatives for non-creepy deep learning

    Jack Moffitt started off his 2019 linux.conf.au talk by calling attention to Facebook's "Portal" device. It is, he said, a cool product, but raises an important question: why would anybody in their right mind put a surveillance device made by Facebook in their kitchen? There are a lot of devices out there — including the Portal — using deep-learning techniques; they offer useful functionality, but also bring a lot of problems. We as a community need to figure out a way to solve those problems; he was there to highlight a set of Mozilla projects working toward that goal.
    He defined machine learning as the process of making decisions and/or predictions by modeling from input data. Systems using these techniques can perform all kinds of tasks, including language detection and (bad) poetry generation. The classic machine-learning task is spam filtering, based on the idea that certain words tend to appear more often in spam and can be used to detect unwanted email. With more modern neural networks, though, there is no need to do that sort of feature engineering; the net itself can figure out what the interesting features are. It is, he said, "pretty magical".

  • Lisp and the foundations of computing

    At the start of his linux.conf.au 2019 talk, Kristoffer Grönlund said that he would be taking attendees back 60 years or more. That is not quite to the dawn of computing history, but it is close—farther back than most of us were alive to remember. He encountered John McCarthy's famous Lisp paper [PDF] via Papers We Love and it led him to dig deeply into the Lisp world; he brought back a report for the LCA crowd.

    Grönlund noted that this was his third LCA visit over the years. He was pleased that his 2017 LCA talk "Package managers all the way down" was written up in LWN. He also gave his "Everyone gets a pony!" talk at LCA 2018. He works for SUSE, which he thanked for sending him to the conference, but the company is not responsible for anything in the talk, he said with a grin.

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.
