  • Music and math: the Kubernetes 1.17 release interview

    Every time the Kubernetes release train stops at the station, we like to ask the release lead to take a moment to reflect on their experience. That takes the form of an interview on the weekly Kubernetes Podcast from Google that I co-host with Craig Box. If you're not familiar with the show, every week we summarise the new in the Cloud Native ecosystem, and have an insightful discussion with an interesting guest from the broader Kubernetes community.

    At the time of the 1.17 release in December, we talked to release team lead Guinevere Saenger. We have shared the transcripts of previous interviews on the Kubernetes blog, and we're very happy to share another today.

    Next week we will bring you up to date with the story of Kubernetes 1.18, as we gear up for the release of 1.19 next month. Subscribe to the show wherever you get your podcasts to make sure you don't miss that chat!

  • New default: tmpfs on /tmp

    We made an important change for our Container Host OS openSUSE MicroOS, which our Kubernetes platform openSUSE Kubic will inherit since it is based on openSUSE MiceroOS: we use now tmpfs for /tmp.

    tmpfs is a temporary filesystem that resides in memory. Mounting directories as tmpfs can be an effective way of speeding up accesses to their files and to ensure that their contents are automatically cleared upon reboot.

    A fresh installation will use tmpfs for /tmp by default. Old installations needs to be converted to this manually, but it is still possible to switch back to use disk space for /tmp. This is especially useful and important, if big files are stored in /tmp.

  • TiddlyWiki, 12 Use-cases and 5 Tips for New Users.

    I have been using TiddlyWiki for years, mainly as personal memo, to-do organizer and encrypted data reserve (to keep track about some of my patients, or while learning). I always recommend this amazing project to my friends, colleagues doctors and developers alike, because I believe the value it gives is far so great than its minimal size and humble look.

    As a self-learner, TiddlyWiki was my main choice and companion to record what I learn, links I collect, code snippets, medical cases and algorithms. It's the only tool I am still using for more than decade.

    I consider a TiddlyWiki is a masterpiece, not in coding but its simplicity and flexibility, needless to say its rich features list.

  • WordPress 5.5 Beta 4

    WordPress 5.5 Beta 4 is now available!

    This software is still in development, so it’s not recommended to run this version on a production site. Consider setting up a test site to play with the new version.

    [...]

    WordPress 5.5 is slated for release on August 11th, 2020, and we need your help to get there!

    Thank you to all of the contributors who tested the beta 3 development release and gave feedback. Testing for bugs is a critical part of polishing every release and a great way to contribute to WordPress.

  • 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.
