• Unravelling complexity in a software-defined vehicles industry | Ubuntu

  Vehicles are becoming more connected, autonomous, shared and electric (the famous CASE acronym). While customers expect new features and upgradability, the software and hardware components enabling such innovations require a different system architecture to function. This is a major change for the automotive industry as it requires new software skills, methodologies and business models. At the same time, automotive manufacturers need to adhere to complex and strict industry standards, and uphold safety-critical functions. In this post, we will focus on the different challenges the industry is facing in terms of hardware and software complexity, cybersecurity and safety. We will also discuss how Original Equipment Manufacturers (OEMs) can learn from software companies to survive this transition towards software-defined vehicles and succeed. [...] On top of this, regulations are becoming very strict, forcing OEMs to provide patches and fixes to common vulnerabilities and exposures (CVE). Taking into account the previously detailed system complexity, it is becoming increasingly necessary to move towards a software-defined holistic context. Only a software-defined approach can provide the required flexibility and scalability that allows companies to comply with regulatory requirements while providing UX updates and handling hardware complexity. Of course, cybersecurity never only relies on software. Hardware vulnerabilities can also occur and usually lead to even worse consequences. Some hardware issues can be patched via software, but usually these CVEs remain valid throughout the system’s lifetime. For example, Meltdown and Spectre, two of the most widespread hardware vulnerabilities in the world, are still present and affecting tons of devices. This means that during hardware conception, cybersecurity must be taken into account in the specifications and system architecture in order to limit these vulnerabilities.

• 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.

• How to Install LXQt Desktop Environment on Debian 11 - ByteXD

  The LXQt environment is a lightweight desktop environment for the Qt application framework. This environment aims to provide a modern and easy-to-use desktop environment for Linux. LXQt is emerging as one of the popular DEs in the Linux world, and it supports the most popular distributions like Arch, Ubuntu, Fedora, and others. In this article, we will show you how to install LXQt Desktop Environment on Debian 11 operating system.

  It started as a request from our tech lead: please help triage these patches. So I lookedat the set of patches and started with what looked like the simplest one:

• 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.

• Raspberry Pi Pico W Powers Fresh Batch of Remote Projects | Tom's Hardware

  Makers Kevin McAleer and Sam Machin show us how to control the new Raspberry Pi Pico W over Wi-Fi using MQTT and Node-RED.

• 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.
