  • Firebird 3.0.9 sub-release is available

    Firebird Project is happy to announce general availability of Firebird 3.0.9 — the latest point release in the Firebird 3.0 series.

    This sub-release offers a few important bugfixes, please refer to the Release Notes for the full list of changes.

  • Elasticsearch 8 and syslog-ng

    General availability of Elasticsearch 8 was announced last week. There were quite a few rumors that it will break compatibility with third party tools. I tested it as soon as I had a little time: I am happy to share that anything I tested with the elasticsearch-http() destination of syslog-ng still seems to work perfectly well with the latest version of Elasticsearch.

  • SIG Node CI Subproject Celebrates Two Years of Test Improvements

    Ensuring the reliability of SIG Node upstream code is a continuous effort that takes a lot of behind-the-scenes effort from many contributors. There are frequent releases of Kubernetes, base operating systems, container runtimes, and test infrastructure that result in a complex matrix that requires attention and steady investment to "keep the lights on." In May 2020, the Kubernetes node special interest group ("SIG Node") organized a new subproject for continuous integration (CI) for node-related code and tests. Since its inauguration, the SIG Node CI subproject has run a weekly meeting, and even the full hour is often not enough to complete triage of all bugs, test-related PRs and issues, and discuss all related ongoing work within the subgroup.

    Over the past two years, we've fixed merge-blocking and release-blocking tests, reducing time to merge Kubernetes contributors' pull requests thanks to reduced test flakes. When we started, Node test jobs only passed 42% of the time, and through our efforts, we now ensure a consistent >90% job pass rate. We've closed 144 test failure issues and merged 176 pull requests just in kubernetes/kubernetes. And we've helped subproject participants ascend the Kubernetes contributor ladder, with 3 new org members, 6 new reviewers, and 2 new approvers.

    The Node CI subproject is an approachable first stop to help new contributors get started with SIG Node. There is a low barrier to entry for new contributors to address high-impact bugs and test fixes, although there is a long road before contributors can climb the entire contributor ladder: it took over a year to establish two new approvers for the group. The complexity of all the different components that power Kubernetes nodes and its test infrastructure requires a sustained investment over a long period for developers to deeply understand the entire system, both at high and low levels of detail.

  • Kubernetes cost management with Kubecost and SUSE Rancher | SUSE Communities

    Kubernetes and containerized workloads have become a de facto standard of the modern IT landscape, delivering unprecedented agility – on-premises, in the cloud, and across clouds. Managing resource costs in this dynamic environment can be challenging for organizations of any size. We’ve invited Kubecost, a SUSE One partner, to share some highlights of its approach and capabilities that enable SUSE Rancher customers to better manage their Kubernetes infrastructure costs.

  • Launchpad News: New domain names for PPAs

    Since they were introduced in 2007, Launchpad’s Personal Package Archives (PPAs) have always been hosted on ppa.launchpad.net. This has generally worked well, but one significant snag became clear later on: it was difficult to add HTTPS support for PPAs due to the way that cookies work on the web.

    Launchpad uses a cookie for your login session, which is of course security-critical, and because we use multiple domain names for the main web application (bugs.launchpad.net, code.launchpad.net, and so on), the session cookie domain has to be set to allow subdomains of launchpad.net. We set the “Secure” flag on session cookies to ensure that browsers only ever send them over HTTPS, as well as the “HttpOnly” flag to prevent direct access to it from JavaScript; but there are still ways in which arbitrary JS on an HTTPS subdomain of launchpad.net might be able to exfiltrate or abuse users’ session cookies. As a result, we can never allow any HTTPS subdomain of launchpad.net to publish completely user-generated HTML that we don’t process first.

  • 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.
