  • How to deploy the Jitsi Meet conferencing server with Ubuntu 22.04 | TechRepublic

    Jitsi is an open-source, free conferencing server that can handle chat, video and VOIP conferencing. It’s a great alternative to the likes of Skype and Zoom. You can quickly deploy Jitsi and use it as an in-house solution or even open it up to the public. I want to show you how easy it is to deploy Jitsi on Ubuntu 22.04. You can deploy this with either a fully qualified domain name or using a server with just an IP address. For simplicity’s sake, I’ll demonstrate using an IP address, which is a great option for an internal solution.

  • Check Your Battery's Health from the Command Line with Battop - OMG! Ubuntu!

    I recently came across a cool terminal app that help you check your battery health from the command line. It’s called Battop and it’s open source software written in Rust. I ran into it after I went looking for a GUI battery status tool for Linux similar to CoconutBattery for macOS (it’s a menu-bar app that shows battery health, condition, capacity, temperature, voltage and so on). A lot of the guides and tutorials that walk through how to check battery info on Linux all agree on one thing: use upower. It is a solid recommendation. Not only is upower very detailed but it’s dead easy to use as it’s enabled out-of-the-box in virtually every major Linux distro out there, Ubuntu included. One downside to using upower is that it’s a little utilitarian. It prints a list and that’s it.

  • Someone Got YouTube Playing on a 40-Year-Old Computer

    They created a combination of hardware and software they dubbed the BlixTerm which took the form of a cartridge connected to one of the PET 600's expansion ports on the back. Inside the cartridge is a Raspberry Pi Zero 2 W which connects to YouTube over wifi, loads a requested video, and then converts the 640x200 grayscale stream to an 80x25 grid of ASCII characters from the PET’s internal ROM.

  • Anvil Announce Secure Raspberry Pi Pico W IoT Toolkit | Tom's Hardware

    Anvil, a popular web applications development tool has today announced a new toolkit developed for the recently released Raspberry Pi Pico W. The toolkit provides a means of communicating between a web application and a Raspberry Pi Pico W using nothing but Python. This new toolkit brings secure IoT applications for the Wi-Fi enabled $6 microcontroller. Applications normally reserved for the more powerful, and hard to come by Raspberry Pi.

  • Reviving a classic Sony PS-X75 record player with Arduino | Arduino Blog

    In 1979, Sony launched the PS-X75 turntable. It quickly gained popularity thanks to its high-fidelity sound output and ease of use. It was easy to use because it was fully automated–a common feature today, but something that was quite exciting at the time. To perform that automation, the PS-X75 contained an integrated circuit that detected record size, dropped the needle, and so on. But that IC was prone to failure. To revive their Sony PS-X75 turntable, MKB-1 used an Arduino Mega to replace the original circuit. Unlike earlier turntable designs, which were often entirely electromechanical, the PS-X75’s IC controls almost all of the turntable’s functions digitally. That means that when the IC fails, the turntable becomes inoperable. Replacement ICs are almost impossible to find and haven’t been manufactured in many years. For most people, this means that the PS-X75 becomes e-waste when that IC bites the dust. But MKB-1 has some reverse-engineering skill and was able to save their PS-X75 by swapping out original IC for an Arduino Mega.

Linux Plumbers Conference and Linux Foundation Leftovers

  • Microconferences at Linux Plumbers Conference: Power Management and Thermal Control – Linux Plumbers Conference 2022

    Linux Plumbers Conference 2022 is pleased to host the Power Management and Thermal Control Microconference The Power Management and Thermal Control microconference focuses on frameworks related to power management and thermal control, CPU and device power-management mechanisms, and thermal-control methods. In particular, we are interested in extending the energy-efficient scheduling concept beyond the energy-aware scheduling (EAS), improving the thermal control framework in the kernel to cover more use cases and making system-wide suspend (and power management in general) more robust. The goal is to facilitate cross-framework and cross-platform discussions that can help improve energy-awareness and thermal control in Linux.

  • 7 CNCF Projects For Building Cloud-Native Networks

    Cloud-native is more than a trend—it’s estimated that by 2023, the majority of new applications will adopt cloud-native components. One aspect of cloud-native is connectivity—networking is essential to enabling containers to talk to one another, especially since multiple containers may comprise a single application. But, it’s not only single containers you have to worry about—architects may want to combine components from multiple clusters, which might be sitting in various clouds or on-premises locations. Cloud-native networking can help ease this tricky process by creating virtual overlay networks on top of existing networks. And if you’re creating an overlay network for your cloud-native communication, many open source tools are at your disposal. Below, we’ll review some of the projects hosted by the Cloud Native Computing Foundation (CNCF) around cloud-native networking. These tools below use the Container Network Interface (CNI), a CNCF-hosted project that specifies standards for ​​configuring network interfaces to work with pods.
