  • Jan-Erik Rediger: Fenix Physical Device Testing

    The Firefox for Android (Fenix) project runs extensive tests on every pull request and when merging code back into the main branch.

    While many tests run within an isolated Java environment, Fenix also contains a multitude of UI tests. They allow testing the full application, interaction with the UI and other events. Running these requires the Android emulator running or a physical Android device connected. To run these tests in the CI environment the Fenix team relies on the Firebase test lab, a cloud-based testing service offering access to a range of physical and virtual devices to run Android applications on.

    To speed up development, the automatically scheduled tests associated with a pull request are only run on virtual devices. These are quick to spin up, there is basically no upper limit of devices that can spawn on the cloud infrastructure and they usually produce the same result as running the test on a physical device.

  • CTCFT 2021-10-18 Agenda

    After the CTCFT this week, we are going to try an experimental social hour. The hour will be coordinated in the #ctcft stream of the rust-lang Zulip. The idea is to create breakout rooms where people can gather to talk, hack together, or just chill.

  • Hacked! Unravelling a data breach

    The bottom line: If you get snagged in a data breach, tie up any loose threads quickly to protect yourself, and stay on top of monitoring your accounts for suspicious activity.

  • Dyn async traits, part 5

    If you’re willing to use nightly, you can already model async functions in traits by using GATs and impl Trait — this is what the Embassy async runtime does, and it’s also what the real-async-trait crate does. One shortcoming, though, is that your trait doesn’t support dynamic dispatch. In the previous posts of this series, I have been exploring some of the reasons for that limitation, and what kind of primitive capabilities need to be exposed in the language to overcome it. My thought was that we could try to stabilize those primitive capabilities with the plan of enabling experimentation. I am still in favor of this plan, but I realized something yesterday: using procedural macros, you can ALMOST do this experimentation today! Unfortunately, it doesn’t quite work owing to some relatively obscure rules in the Rust type system (perhaps some clever readers will find a workaround; that said, these are rules I have wanted to change for a while).

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.
