  • Looking into the future of collaborative commons | Opensource.com

    I read Jeremy Rifkin's book The Zero Marginal Cost Society: The Internet of Things, the Collaborative Commons, and the Eclipse of Capitalism, which has a strong connection to open organization principles, particularly community building. Rifkin also writes about the future of green energy generation and energy use in logistics. In the previous articles in this series, I wrote about the communication internet being joined by the advancement of the energy (producing, sharing, consuming) internet. In this final part of the series, I look at Rifkin's thoughts regarding logistics (moving, storing, sharing) internet, and other economic sectors.

    There are public transportation systems like roads, commuter trains, light rail, and buses that are supported by taxes. There are also private transportation options such as private ocean shipping companies, private cars, bicycles, and walking. All these modes of transportation will go through changes with an IoT standardized system that communicates with many moving vehicles. This will make movement of both people and goods more efficient (less waste and more full utilization of capacity). Established protocols will allow firms to collaborate with each other to a more detailed degree. Furthermore, inventory storage will become more efficient. Redundancies and inefficiencies will be identified and reduced.

    This can be achieved by a distributed, collaborative, laterally scaled internet communication system, with its open system configuration and commons-style management, as a model for radically transforming global logistics.

  • 17 open-source, free Habit tracker apps for Windows, Android, Linux, macOS and the web

    The habit is something you usually do on a regular basis. It can be a part of a regular routine for work, lifestyle or both.

    Let us say, like morning work, exercise, reading newspaper, and brushing your teeth.

    There are good habits and bad habits, and as an example: smocking is a bad habit, drug addiction starts as a bad habit.

  • New Steam Games with Native Linux Clients - 2022-05-24 Edition - Boiling Steam

    We are publishing this update a little late this time, but there’s quite a lot of new titles! Between 2022-05-17 and 2022-05-24 there were 44 New Steam games released with Native Linux clients. For reference, during the same time, there were 448 games released for Windows on Steam, so the Linux versions represent about 9.8 % of total released titles.

  • Stupid RCU Tricks: Is RCU Watching? - Paul E. McKenney's Journal — LiveJournal

    It is just as easy to ask why RCU wouldn't be watching all the time. After all, you never know when you might need to synchronize!

    Unfortunately, an eternally watchful RCU is impractical in the Linux kernel due to energy-efficiency considerations. The problem is that if RCU watches an idle CPU, RCU needs that CPU to execute instructions. And making an idle CPU unnecessarily execute instructions (for a rather broad definition of the word “unnecessary”) will terminally annoy a great many people in the battery-powered embedded world. And for good reason: Making RCU avoid watching idle CPUs can provide 30-40% increases in battery lifetime.

    In this, CPUs are not all that different from people. Interrupting someone who is deep in thought can cause them to lose 20 minutes of work. Similarly, when a CPU is deeply idle, asking it to execute instructions will consume not only the energy required for those instructions, but also much more energy to work its way out of that deep idle state, and then to return back to that deep idle state.

    And this is why CPUs must tell RCU to stop watching them when they go idle. This allows RCU to ignore them completely, in particular, to refrain from asking them to execute instructions.

  • AmigaOne X1000/X5000 Remains Well Supported With PowerPC Linux

    Despite being expensive and having been sold out for quite some time at the main Amiga Dealers, two days after Linus Torvalds' release of Linux 5.18, Christian "xeno74" Zigotzky made the latest PPC kernel available for the AmigaOne X1000/X5000. Here and here are some screenshots. Linux PPC performs well on AmigaOne computers. For example, here is a 5-year-old YouTube AmigaOne X5000 demonstration video.

  • How to select your embedded systems operating system: OS characteristics - Embedded.com

    Embedded system developers have a wide range of operating systems available to them today. Of course, the most straightforward operating system is to have no operating system! However, many systems today are complex, connected systems where an operating system might be required. When required, developers will often look to use a real-time operating system (RTOS) or Linux to help them manage the complexity. Unfortunately, it’s not always clear-cut how to choose between bare metal, RTOS, or Linux. Each option has its advantages and disadvantages.

  • 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.

Red Hat Hires a Blind Software Engineer to Improve Accessibility on Linux Desktop

Accessibility on a Linux desktop is not one of the strongest points to highlight. However, GNOME, one of the best desktop environments, has managed to do better comparatively (I think). In a blog post by Christian Fredrik Schaller (Director for Desktop/Graphics, Red Hat), he mentions that they are making serious efforts to improve accessibility. Starting with Red Hat hiring Lukas Tyrychtr, who is a blind software engineer to lead the effort in improving Red Hat Enterprise Linux, and Fedora Workstation in terms of accessibility. Read more
