  • Mozilla VR Blog: New Avatar Features in Hubs

    It is now easier than ever to customize avatars for Hubs! Choosing the way that you represent yourself in a 3D space is an important part of interacting in a virtual world, and we want to make it possible for anyone to have creative control over how they choose to show up in their communities. With the new avatar remixing update, members of the Hubs community can publish avatars that they create under a remixable, Creative Commons license, and grant others the ability to derive new works from those avatars. We’ve also added more options for creating custom avatars.

    When you change your avatar in Hubs, you will now have the opportunity to browse through 'Featured' avatars and ‘Newest’ avatars. Avatars that are remixable will have an icon on them that allows you to save a version of that avatar to your own ‘My Avatars’ library, where you can customize the textures on the avatar to create your own spin on the original work. The ‘Red Panda’ avatar below is a remix of the original Panda Bot.

  • QMO: Firefox 69 Beta 14

    As you may already know, Friday August 16th – we held a new Testday event, for Firefox 69 Beta 14.

  • Async Stack Traces in Rust

    One neat result of Rust’s futures and async/await design is that all of the async callers are on the stack below the async callees. In most other languages, only the youngest async callee is on the stack, and none of the async callers. Because the youngest frame is most often not where a bug’s root cause lies, this extra context makes debugging async code easier in Rust.

  • Facebook's HHVM Begins Seeing Rust Rewrite

    Facebook's HHVM implementation that started off as a high performance PHP5 implementation but is now just focused on powering their own Hack programming language is beginning to see some of its code rewritten in Rust.

    HHVM 4.20 was released on Tuesday and with this release they have been transitioning some of their code from OCaml to Rust.

  • Things I Learnt from a Senior Software Engineer

    year ago, I started working full-time at Bloomberg. That’s when I imagined writing this post. I imagined myself to be full of ideas that I could spit out on paper when the time comes. Just one month in, I realised it won’t be that easy: I was already forgetting things I learnt. They either became so internalized that my mind tricked me into believing I always knew them1, or they slipped my mind.

    That’s one of the reasons I started keeping a human log. Every day, whenever I came across an interesting situation, I logged it. All thanks to sitting next to a senior software engineer, I could closely observe what they were doing, and how it was different from what I would do. We pair-programmed a lot, which made doing this easier. Further, in my team culture it’s not frowned upon to “snoop behind” people writing code. Whenever I sensed something interesting going on, I’d roll around and watch what was happening. I always had the context, thanks to regular standups.

    I sat next to a senior software engineer for a year. Here’s what I learnt.

  • Quansight Labs Dask Update

    Finally, there's been a push for a more coordinated effort towards project maintenance and development by core Dask maintainers at Quansight, Anaconda, and NVIDIA. As part of this effort, we spend a portion of our work week on day-to-day project maintenance tasks (e.g. responding on issues, reviewing pull requests, fixing CI systems, etc.) as well as working on contributions that require significant amounts of time or expertise to implement (e.g. large-scale refactoring, adding new features, writing documentation, etc.). Today, Dask users typically get a quicker response from a core maintainer when opening an issue or pull request, in part, because of these efforts. I, and perhaps other core maintainers, hope to write more about this process in the future.

  • Little Trouble in Big Data – Part 3

    We have shown how a simple “How do I use mmap()?” mentoring project has grown beyond its initial scope and how we have used mmap, Eigen,parallel_for/parallel_reduce, flow graphs [maybe replace these two with Intel Thread Building Blocks] and zlib to nicely make the problem tractable. This has shown a nice set of performance improvements whilst at the same time keeping the disk and RAM usage within feasible limits.

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.
