  • Piper Make: First Drag-and-Drop Coding Platform for Raspberry Pi Pico

    In 2019 we saw Piper’s Computer Kit 2, which was a DIY Raspberry Pi 3 Computer for educational purposes. The kit was for kids to educate them on building their own computers and the basics of programming in electronics. This year the company has come up with another educational platform. Meet Piper Make.

    The newly launched Raspberry Pi Pico is capable of a wide range of applications but directly working on the development board for exploring these applications could be difficult for beginners. Additionally, prototyping a project or an application before implementing it is an ideal way for starting. Hence. Piper has launched its first drag-and-drop coding platform for the Raspberry Pi Pico which allows hands-on prototyping for the users.

  • Peter Czanik: Syslog-ng & Pi day

    Today is March 14th, or as many geeks refer to it: Pi day. On this occasion, I would like to show you a syslog-ng configuration, which prints a huge π on the screen, and two recent articles that feature syslog-ng on the Raspberry Pi.

  • brrt to the future: Why bother with Scripting?

    Many years back, Larry Wall shared his thesis on the nature of scripting. Since recently even Java gained 'script' support I thought it would be fitting to revisit the topic, and hopefully relevant to the perl and raku language community.

    The weakness of Larry's treatment (which, to be fair to the author, I think is more intended to be enlightening than to be complete) is the contrast of scripting with programming. This contrast does not permit a clear separation because scripts are programs. That is to say, no matter how long or short, scripts are written commands for a machine to execute, and I think that's a pretty decent definition of a program in general.

    A more useful contrast - and, I think, the intended one - is between scripts and other sorts of programs, because that allows us to compare scripting (writing scripts) with 'programming' (writing non-script programs). And to do that we need to know what other sorts of programs there are.

  • Twenty years ago...

    Twenty years ago today I released my first CPAN module: Fork::Queue.

    Then there was a group of people supervising module names, and they advised me to move it under the Proc namespace and so it became Proc::Queue.

    A couple of weeks before, a bug on one of my scripts had fork-bombed a production box. I barely remember the details now... just that my manager had a serious conversation with me about the incident.

  • Java 16 Pattern Matching Fun

    Java 16 brings Pattern Matching for instanceof. It’s a feature with exciting possibilities, though quite limited in its initial incarnation.

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.
