  • Raspberry Pi Pico Arduino Core released for RP2040 boards

    Since Arduino plans to launch its own Raspberry Pi RP2040 based board with Arduino Nano RP2040 Connect, one would have expected software support for the Arduino IDE would have come from the company itself.

    But apparently, the developer community, or more exactly Earle F. Philhower, III did not feel like waiting. He had previously written ESP8266Audio library for audio file and I2S sound playing routines for ESP8266 & ESP32, and has recently released Raspberry Pi Pico Arduino Core on arduino-pico Github repository.

  • Crazy Idea Number 615: Variable Priced Power Systems Partitions - IT Jungle

    When you stare down the blank page as much as I have in my career, you learn to not be afraid of that blank page. If you look at it long enough – usually for only a few minutes – ideas flip into existence like quantum particles spinning their curlicues. Most of them are silly, some are utterly useless, but eventually you get one that is worth following to see where it might go.

    So it is with an idea that popped into my head, which was a daydream about IBM creating variable priced partitions on the Power Systems machines. This would stand in stark contrast to how Big Blue prices and sells Power Systems today, but certainly could be an overlay on top of existing metered pricing metrics or lease prices or outright acquisition prices.

    Today, when you buy a Power Systems server, you pay for it based on what it is: It is a Model 9009-22A with a feature #EP16 processor module, which has a “Cumulus” Power9 processor with four-cores running at a base speed of 2.8 GHz, plus two feature #EP46 processor core activations, plus eight feature #EM63 32 GB memory sticks, plus a feature #EC59 storage backplane for NVM-Express flash, plus four feature #EC5C 3.2 TB flash adapters, plus one feature #EC37 two-port 10 Gb/sec Ethernet adapter, and so on. You have the IBM configurator build the whole system, add the operating system on a per core basis, add its features, kick out a list price, and then the customer argues for a discount and usually gets something but not much because, frankly, if they need IBM i, it is not like there are a lot of choices.

    If they don’t like the deal, they can backstep to a certified pre-owned machine with Power8 or Power7+ processors, which would be cheaper but which has a much shorter technical life because these machines will not future releases at some point. Or they can defer the whole thing and pray their current machine doesn’t break or run out of capacity.

  • Testing Apicurio Registry’s performance and scalability

    Apicurio Registry is the upstream project for Red Hat Integration’s Service Registry component. Developers use Apicurio Registry to manage artifacts like API definitions and data structure schemas.

    Apicurio Registry can maintain tons of artifacts, and it needs a way to store them. The registry supports several storage options, including Apache Kafka, Infinispan, and PostgreSQL. Knowing the performance characteristics of each storage option helps developers choose the appropriate storage for different use cases.

    Recently, Red Hat’s Performance & Scale team analyzed how Apicurio Registry performs under various storage configurations. In this article, we share the results of our performance and scalability testing on Apicurio Registry.

  • Parabola/i686: desktop users should refrain from upgrading

    users of a GTK-based desktops (LXDE, MATE, possibly others) on the i686 system, should refrain from upgrading for some time, or else the desktop may not start properly - this bug does not affect X86_64

  • antiX kernel updates

    There have been various security patches applied upstream so users are strongly advised to update to the latest kernels via Package Installer, synaptic or cli-aptiX.

  • Glaucus Linux α = musl-c-library toybox-utilities init=finit

    Virtualbox has its own converting utility. The image constitutes of a whole drive and a single linux partition, so don’t even try burning the .img into a single partition. It also has a minimal bootloader embeded in it, so make sure it is the first drive in a series or /dev/sda in linux, or it will not boot. If it is mounted to another system it can be edited, and so can its bootloading configuration, so feel free to experiment.

    The utilities to build software in it are not complete yet, so this is more like a demo, don’t plan to make it a work system or a server of some sort. But whatever is done already seems like it has careful attention to detail and seems 100%. So this is very promising compared to projects that seem to be published a bit sloppy, like our beloved mere linux that has incompatible libraries in it. Mere-linux by the way has been recently gotten some attention from its creator and is moving a step or two.

  • Plan 9 transferred to the Plan 9 Foundation

    The funky second OS from the Unix masterminds, Plan 9, has been fully transferred to the Plan 9 Foundation, and it’s been released under the MIT license.

  • 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.
