  • MERA, Mocana, and Osaka NDS Join Automotive Grade Linux

    Automotive Grade Linux, a collaborative cross-industry effort developing an open source platform for connected car technologies, announces three new members: MERA, Mocana, and Osaka NDS.

    “With the support of 11 major automakers, we are increasingly seeing more vehicles in production with AGL,” said Dan Cauchy, Executive Director of Automotive Grade Linux at the Linux Foundation. “We look forward to working with all of our new members as we continue to expand the AGL platform and the global ecosystem of products and services that support it.”

  • I had to build a web scraper to buy groceries

    Here’s the deal; very few supermarket chains in Turkey have online stores. Migros Sanalmarket is one of them and it’s arguably the best one. But they don’t have unlimited resources, obviously. When everybody decided to switch to online shopping all of a sudden, they couldn’t handle that demand spike. Even though their delivery system works from 8:30 AM to 10:00 PM every day, it’s virtually impossible to find an empty slot, that is if you play nicely.

  • How to mock in Python? – (almost) definitive guide

    Mock is a category of so-called test doubles – objects that mimic the behaviour of other objects. They are meant to be used in tests to replace real implementation that for some reason cannot be used (.e.g because they cause side effects, like transferring funds or launching nukes). Mocks are used to write assertions about the way they are used – e.g. if they were called, which arguments were used etc. It is a flagship technique of interaction-based testing – checking how objects under test use their collaborators (other objects).

    I recently added experimental support for Jupyter Notebooks to Rich.

  • How to Use any() in Python

    As a Python programmer, you’ll frequently deal with Booleans and conditional statements—sometimes very complex ones. In those situations, you may need to rely on tools that can simplify logic and consolidate information. Fortunately, any() in Python is such a tool. It looks through the elements in an iterable and returns a single value indicating whether any element is true in a Boolean context, or truthy.

  • Add developer comments to your extension’s listing page on addons.mozilla.org

    In November 2017, addons.mozilla.org (AMO) underwent a major refresh. In addition to updating the site’s visual style, we separated the code for frontend and backend features and re-architected the frontend to use the popular combination of React and Redux.

    With a small team, finite budget, and other competing priorities, we weren’t able to migrate all features to the new frontend. Some features were added to our project backlog with the hope that one day a staff or community member would have the interest and bandwidth to implement it.

    One of these features, a dedicated section for developer comments on extension listing pages, has recently been re-enabled thanks to a contribution by community member Lisa Chan. Extension developers can use this section to inform users about any known issues or other transient announcements.

    [...]

    We’d like to extend a special thanks to Lisa for re-enabling this feature. If you’re interested in contributing code to addons.mozilla.org, please visit our onboarding wiki for information about getting started.

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.
