  • ROS Kinetic migration and its challenges – A community perspective.

    ROS Kinetic has come to EOL. We have discussed the impact of EOL in the past, but with its final sync out on May 12th, ROS Kinetic is no longer supported. Together with Ubuntu Xenial, both distributions will no longer receive security updates or bug fixes.

    ROS second LTS release became the largest rosdistro with 1,233 repositories over the last 5 years. We want to join our partner, Open Robotics, in thanking all of you who contributed to making ROS Kinetic a milestone in robotics history.

    But for all of us still working with Kinetic, in our deployed robots, labs or universities, two questions arise: where do I migrate to and what are the challenges?

    To answer these questions, we asked our community what they think. So throughout April, we conducted 2 small polls on LinkedIn and Twitter. Two main questions were asked.

  • Loved Celeste? You're going to want to play brain-twisting precision platformer Sunblaze

    Celeste was tough, incredible and beautiful but controller-throwing annoying and Sunblaze sits along nicely beside it now as one of my new favourites. Note: key provided by the developer.

    Developed by Games From Earth with Bonus Stage Publishing, Sunblaze tells the story of Josie as you go wall-jumping and dashing through her retired superhero dad's training simulator. This is a platformer that won't hold your hand, in fact it'll take it and then use it to throw you over the edge and expect you to figure it out. It's damn good though, sweat-inducing challenging and it looks seriously pretty too.

    [...]

    It seems like a really nice set of features there as they said "we want as many people to be able to enjoy Sunblaze as possible" which is why they also support Linux with it too!

  • openSUSE Leap 15.3 Released, Becomes a Free Counterpart to SLE

    The new openSUSE Leap 15.3 is based on SUSE Linux Enterprise 15 SP3 and it is supported until December 2022.

    After almost a year of development, the openSUSE project has presented a new version of its stable Linux distribution openSUSE Leap 15.3. The newest minor version is the most recent, rock-solid addition to the openSUSE 15.x series that carries all the positive attributes of its predecessors.

    There is one huge change from the previous Leap versions. openSUSE Leap 15.3 is built not just from SUSE Linux Enterprise source code like in previous versions, but built with the exact same binary packages, which strengthens the flow between Leap and SUSE Linux Enterprise. Put simply, openSUSE Leap will become a free counterpart to SUSE Linux Enterprise Server (SLES) and the server variant (SLED) without commercial support.

  • openSUSE Community Releases Leap 15.3

    OpenSUSE Leap 15.3, the most recent addition to the openSUSE 15.x series built using the same exact binary packages as SUSE Linux Enterprise, is now officially available.

    There is one huge change from the previous Leap versions. openSUSE Leap 15.3 is built not just from SUSE Linux Enterprise source code like in previous versions, but built with the exact same binary packages, which strengthens the flow between Leap and SLE like a yin yang.

    This release is hugely beneficial for migration projects and user acceptance testing. Large development teams gain added value by using openSUSE Leap 15.3 to optimally run and test workloads that can be lifted and shifted to SUSE Linux Enterprise Linux 15 SP3 for long-term maintenance.

  • 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.
