Ubuntu: Split Personality Snaps, AVs and Ceph

  • Split Personality Snaps

    Broadly speaking, most snaps in the Snap Store fall into one of two categories, desktop applications and server daemons. The graphical applications such as Chromium and Spotify use desktop files, which ensure they can be opened on demand by any user via a menu or launcher. The server applications such as NextCloud and AdGuard-Home typically have systemd units, which control their automatic (background) startup.

    Taking an existing desktop application and converting it to an always-running appliance leads to some interesting engineering challenges. Applications and games tend to have expectations for what programs and services are accessible at runtime. which need mitigating. Application confinement in snaps on Ubuntu Core means some assumptions about file and device access may no longer apply.

    We will typically need to stand-up a configuration in which the application believes it’s running in a standard desktop environment. The application will also need the startup automated in an appliance setting, but launched on demand when in a desktop environment.

    We can be quite creative with snaps and build a “split personality” snap that can run both as a desktop application and as an appliance!

  • Open source holds the key to autonomous vehicles

    A growing number of car companies have made their autonomous vehicle (AV) datasets public in recent years.

    Daimler fueled the trend by making its Cityscapes dataset freely available in 2016. Baidu and Aptiv respectively shared the ApolloScapes and nuScenes datasets in 2018. Lyft, Waymo and Argo followed suit in 2019. And more recently, automotive juggernauts Ford and Audi released datasets from their AV research programs to the public.

    Given the potential of self-driving cars to considerably disrupt transportation as we know it, it is worth taking a moment to explore what has motivated these automotive players — otherwise fiercely protective of their intellectual property — to openly share their precious AV datasets with each other and with the wider world.

    [...]

    In the true spirit of open source, a symbiotic relationship is established from sharing AV datasets with the public. Researchers gain recognition for their novel insights. Developers build an industry repute for contributions to open source projects. And companies can integrate these new advancements into their own products, thus strengthening their portfolio and bringing new features to their customers faster.

    By allowing more people to contribute to the field, car companies can harness the economics of open source and benefit from faster software cycles, a more reliable codebase, and volunteer help from some of the brightest minds in the world.

    Automotive companies are beginning to understand this, and the industry will greatly benefit if this trend becomes the default.

  • Ceph storage on VMware

    If you were thinking that nothing will change in your VMware data centre in the following years, think again. Data centre storage is experiencing a paradigm shift. Software-defined storage solutions, such as Ceph, bring flexibility and reduce operational costs. As a result, Ceph storage on VMware has the potential to revolutionise VMware clusters where SAN (Storage Area Network) was the incumbent for many years.

    SAN is the default storage for VMware in most people’s minds, but Ceph is gaining momentum. In this blog, we will do a high-level comparison of SAN and Ceph to highlight how Ceph storage on VMware makes sense as the traditional data centre is moving towards a world of low operating costs through automation that leaves space for more R&D and innovation.

  • 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.
