  • Blog about what you've struggled with

    But if you don’t remember what was hard about something, not all is lost! It’s definitely possible to write about a topic that somebody else is struggling with. I find that the easiest way to do this is to first teach the topic, so here’s a quick story about that.

    In 2019, I wrote a zine about SQL. When I started, I thought it would be easy because I was pretty comfortable with SQL – I’d done a LOT of data analysis in SQL and so I thought I could explain it.

    But I couldn’t have been more wrong. It turned out that when I started I had no idea what was actually challenging about learning SQL.

    I spent a lot of time talking to a friend who was new to SQL about how it worked, and we realized that one of the blockers was that it wasn’t obvious to them in what order a given SQL query was running. So I wrote SQL queries don’t start with SELECT, and a bunch of related examples and that helped a lot of people understand SQL queries better!

    The cool thing about this is that when I dig into something that I think is easy but someone else is struggling with, often I learn something new too. For example I did sort of know in what order SQL queries ran but I’d never really thought about it explicitly. And being more explicit about how it worked helped me understand window functions better, which was something I was a bit shaky on!

  • Intel Open-Source Stack Enables oneAPI Level Zero For Rocket Lake, Alder Lake S

    A bit late to the game on the Rocket Lake side but ahead as usual when it comes to Alder Lake S, Intel's engineers maintaining the open-source Compute Runtime for Linux systems have now flipped on the Level Zero support.

    Rocket Lake and forthcoming Alder Lake S processors with Xe Graphics should now have working Level Zero support with Intel Compute Runtime 21.20.19883. Enabling Rocket Lake and Alder Lake S Level Zero support is the main highlight of today's Compute-Runtime update plus the cl_intel_sharing_format_query extension is also now enabled.

  • Daniel Stenberg: The curl user survey 2021

    For the eighth consecutive year we run the annual curl user survey again in 2021. The form just went up and I would love to have you spend 10 minutes of your busy life to tell us how you think curl works, what doesn’t work and what we should do next.

    We have no tracking on the website and we have no metrics or usage measurements of the curl tool or the libcurl library. The only proper way we have left to learn how users and people in general think of us and how curl works, is to ask. So this is what we do, and we limit the asking to once per year.

  • Ubuntu Blog: Canonical’s first DockerCon

    May 27th will be Canonical’s first time at a DockerCon event. That’s exciting!

    Since our joint announcement back in November, the relationship between Canonical and Docker has become stronger as more projects arise. There’s still a lot to be done in a cloud-native world to make Open Source available to everyone in its purest form.

    We strongly believe in Open Source Software, and our mission hasn’t changed. Our vision, however, has been more focused recently on Cloud and Security. Now is a very special time as we’ve got the motivation, the ability, and the opportunity.

  • Call for Papers - Qt Developer Conference - KDAB

    The Call for Papers for KDAB’s upcoming event, Qt DevCon, is now open. We are planning to make this our first in-person event after the shut-down. The event will take place September 28-30, featuring 1 training day and 2 days of technical talks from developers, for developers.


    This conference aims to help the attendees become even better Qt programmers. Talks about general aspects of programming may be off-topic for this conference (as interesting as they may be). For instance, a talk like “C# for Qt developers” is off-topic; a talk like “Here’s what Qt should steal from WForms” could be accepted.

  • Chrome crashing on Windows 10 and Linux now has a fix

    A lot of people rely on the Web these days not just to say informed or connected but also to work. Web browsers have become critical pieces of software on any platform, so when those break, the Internet is filled with complaints and demands for explanations. That is what transpired over the weekend when Google Chrome on Windows 10 started crashing left and right. Google did quickly push out a fix and its solution is just as strange as the bug it fixes.

  • Move of official IRC channels to

    As some of you may have read over the past days, there has been an ownership dispute over the network. The IRC network has been used by Arch Linux and many other projects over the past decades as a platform for discussion and support

  • 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.
