  • Red Hat Launches CodeReady Workspaces Kubernetes IDE
  • The First Kubernetes-Native Developer Environment

    From a newly introduced technology to a widely relied upon platform in just a few years, Kubernetes has become an integral part of many organization’s cloud-native solutions - including container-based development environments.

    The challenge with building and deploying applications in any Kubernetes distribution is that it’s difficult for a developer to set up a Kubernetes environment that enables fast, iterative development cycles. As a result, some development teams fall back to using containers on their laptops and only seeing how things run in Kubernetes after they’ve merged code back to the origin code repository and triggered a continuous integration (CI) job.

    This is problematic as Kubernetes has unique execution behaviors that might necessitate code changes or optimizations. Waiting to do these until after code is merged back to master is inefficient and can introduce problems in the master branch that affect other developers.

    Red Hat CodeReady Workspaces is the industry’s first Kubernetes-native integrated development environment (IDE). It makes it easy for developers to have a fast, “locally hosted-style” development experience directly inside Kubernetes and helps development teams avoid the “it works on my machine” problem.

  • TensorFlow.js: machine learning for the web and beyond

    If machine learning and ML models are to pervade all of our applications and systems, then they’d better go to where the applications are rather than the other way round. Increasingly, that means JavaScript – both in the browser and on the server.

    TensorFlow.js brings TensorFlow and Keras to the the JavaScript ecosystem, supporting both Node.js and browser-based applications. As well as programmer accessibility and ease of integration, running on-device means that in many cases user data never has to leave the device.

  • Interviewing tips for junior engineer

    Make sure to highlight any interesting project you worked on, technical or otherwise. Recruiters love discussing actual accomplishment. Back when I started, I had a few open source projects and articles written in technical magazines that I put on my resume. Nowadays, that would be a GitHub profile with personal (or professional, if you're lucky) projects. You don't need to rewrite the Linux kernel, but if you can publish a handful of tools you developed over the years, it'll help validate your credentials. Just don't go fork fancy projects to pad your GitHub profile, it won't fool anyone (I know, it sounds silly, but I see that all too often).

    Another thing recruiters love is Hackerrank, a coding challenge website used by companies to verify the programming skills of prospective candidates. It's very likely US companies will send you some sort of coding challenge as part of the interview process (we even do it before talking to candidates nowadays). My advise is to spend a few weekends building a profile on Hackerrank and getting used to the type of puzzle they ask for. This is similar to what the GAFA ask for in technical interviews ("quicksort on a whiteboard" type of questions).

    At the end of the day, I expect a junior engineer to be smart and excited about technology, if not somewhat easily distracted. Those are good qualities to show during an interview and on your resume.

  • Modify the enemy sprite’s animation

    After we have finished creating our first animated enemy sprite in the previous chapter we will need to further modify that animation class because I have found numerous shortages in the previous program. In the previous program 1) We only create a single counter to handle the sprite animation for all five enemy objects which is simply unrealistic because during the game not every enemy will move to the same frame on the sprite sheet due to the change of the direction of that enemy. 2) There is no adjustment on the image’s transition speed at all, we need to slow down the image transition process so the image will not change too fast.

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.
