  • GitLab 10.8 open sources push mirroring

    GitLab 10.8 was released this week with the open sourcing of a highly requested feature. The company announced its push mirroring capability is now open sourced.

    Push mirroring was originally introduced as a paid feature, but GitLab says it is one of the most frequently requested to be moved into the open-source codebase.

    This move will add a few new use cases for GitLab Core users, such as freelance developers being able to mirror client repos and users migrating to GitLab being able to use push mirroring to ease the migration path.

  • How Security Can Bridge the Chasm with Development

    Enhancing the relationships between security and engineering is crucial for improving software security. These six steps will bring your teams together.

    There's always been a troublesome rift between enterprise security teams and software developers. While the friction is understandable, it's also a shame, because the chasm between these teams makes it all the more challenging to build quality applications that are both great to use and safe.

  • Which Programming Languages Use the Least Electricity?

    Can energy usage data tell us anything about the quality of our programming languages?

    Last year a team of six researchers in Portugal from three different universities decided to investigate this question, ultimately releasing a paper titled “Energy Efficiency Across Programming Languages.” They ran the solutions to 10 programming problems written in 27 different languages, while carefully monitoring how much electricity each one used — as well as its speed and memory usage.

  • How Java EE found new life as Jakarta EE

    The title of this post may seem strange, but if you look a bit into Java EE's recent history, it will make sense.

    Originally, Sun started and ran Java Enterprise Edition, and later Oracle took over after it acquired Sun. Specifications were driven by a Sun/Oracle-governed process. At more or less regular intervals, they made a new version of the specification available, which was implemented by the server vendors. Those vendors had to license the technology compatibility kits (TCKs) and brand from Oracle.

    Let's fast-forward a bit. In 2013, Java EE 7 was released, and Oracle began work on EE8, but it did not progress quickly. Meanwhile, new technologies like Docker and Kubernetes came along and changed the way applications run. Instead of running a single fat server process on a big machine, the software is now split into smaller, independent services that run in a (usually) Docker container orchestrated by Kubernetes.

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.
