  • Why Every Linux User Needs To Learn Awk - YouTube

    Awk is one of those tools that every linux user has on their system but they probably only use it for fairly simple tasks, so today I thought I'd explain not only what awk but why you should use it and compare it some other Linux utils like sed.

  • Arm Neoverse N2 Support Added To The LLVM Clang 12 Compiler - Phoronix

    In September Arm began adding Neoverse N2 support to the open-source compilers initially with GCC and now the support has been merged into LLVM Clang 12 as well.

    The Neoverse N2 "Perseus" core was outlined in September as a follow-on design to the successful Neoverse N1. The N2 aims to provide 40% more performance over the N1 for single-threaded performance. The N2 is intended for use from the cloud to enterprise networking devices to edge computing.

  • Qt 6.0 RC and timelines for 6.1 and 6.2

    Hi all,

    First of all, I wanted to thank everybody for the hard work towards getting Qt 6.0 out of the door. We now have a first RC out, so we’re definitely getting very close to the 6.0.0 release.

    With that and the fact that we now have a 6.0 branch, it’s also time to start looking a bit ahead towards 6.1 and 6.2.

    We have long discussed, that the timing of our feature releases to be just before summer and Christmas vacation is a bit unfortunate, as we have little slack for delays without going into the vacation period. Especially the releases in December have sometimes been difficult in that respect. So we’d like to push the schedule a bit and move the minor releases towards a Spring/Autumn schedule.

    A somewhat shorter release cycle directly after 6.0 is probably a good idea anyway, as we will probably still need to do changes/fixes that don’t quite fit with our policy for patch level releases.

    So the idea is to shorten the release cycle for Qt 6.1 a bit and focus mainly on bug fixing and stability for that release. We’d aim for a feature freeze by the end of January, and a final Qt 6.1.0 release end of April.

    6.2 would then also happen a bit earlier, with a feature freeze in June and a release end of September.

    Content wise, I believe we’ll start seeing more and more of the add-ons from Qt 5 being supported over the next 6-9 months, and I believe that with Qt 6.2 we will have brought most modules that we supported in Qt 5.15 over to Qt 6.

    Cheers,
    Lars

  • Qt 6.1, Qt 6.2 Expected To Come Sooner With Tightened Release Cycles - Phoronix

    Qt 6.0 is releasing in December and The Qt Company is already drafting plans for the release cycles of Qt 6.1 and Qt 6.2 LTS next year.

    Normally Qt is on a six-month release cadence but next year's Qt 6.1/6.2 releases will likely be tightened up both to address a long-standing gripe of the current timing that often puts new releases around summer holidays and the Thanksgiving~Christmas holiday season. To try to move off those May and November~December release windows, they are looking at tightening up the cycles for Qt 6.1 and Qt 6.2, with the latter being the first long-term support release of the Qt6 series.

    Lars Knoll is proposing that Qt 6.1 be shipped by the end of April which would put the feature freeze already at the end of January. But for Qt 6.1 the emphasis anyhow will likely be on bug fixing and stability improvements after all the changes in Qt 6.0, so a tightened up Qt 6.1 release makes sense.

  • 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.
