  • 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.

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.

  • 6 Takeaways from Linux Foundation’s 10th Annual Open Source Jobs Report

Chromium and Firefox: Bugs, Manifest, and Translations

  • Bounty or paid work offered to fix subtle Chromium bug • The Register

    For the past three months, an elusive bug in Google's open-source Chromium project has been causing a small percentage of Chrome extensions to silently fail. The bug affects about three to five percent of users of several popular Chrome browser extensions, according to Jói Sigurdsson, founder and CEO of CrankWheel, maker of a screen-sharing extension for sales teams. As described in the Chromium bug report, event handlers registered via chrome.browserAction.onClicked.addListener sometimes will fail to get dispatched when the associated button or icon is clicked by the user. For an individual using an affected extension, the result would be that the extension's button just stops responding to click events.

  • Short Topix: GMail Trick Reveals Who Is Selling Your Data

    Anyone who follows web browser development even a little has heard of Google's push for the adoption of Manifest V3 and the havoc it is anticipated to bring to many web browser extensions. Most significantly, Manifest V3 eliminates Web Request API, and replaces it with Declarative Net Request API. This change will seriously cripple many ad blocker extensions, which rely on the Web Request API to effectively block unwanted ads on websites visited by the end user. Currently, no new Chrome extensions are being accepted that are based on Manifest V2, which features the Web Request API. Starting in June 2023, Google will no longer allow extensions based on Manifest V2 to continue to run, replacing Manifest V2 with Manifest V3. Mozilla, on the other hand, plans to start implementing Manifest V3 in late 2022. But, Mozilla also plans to maintain support for the Web Request API from Manifest V2, allowing ad blocking browser extensions to continue to work. If you are a Chromium user (or the user of any browser based on it, such as Google Chrome, Opera, Brave, etc.), the implementation of Manifest V3 has already begun. When fully implemented, expect your ad blockers to either cease functioning or to be severely crippled under Chromium-based browsers. It makes sense that Google would want to cripple ad blockers. Consider that the vast majority of Google's fortunes are made from selling advertising, especially advertising that is targeted at individual users. If an ad is blocked, it's not viewed by the end user, and Google gets no money when you cannot view it. Also, when you can't view it, you can't click through the ad to visit the advertiser's website. Those "click counts" are important, especially if you own the website on the other end, or if you sell advertising based on click counts. Developers of web browser extensions – especially ad blocker extensions – have been very vocal about the implementation of Manifest V3. None have been more vocal than Raymond Hill, the creator of the uBlock Origin ad and content blocker. Hang on to your seats, gang. This is going to be one rocky, bumpy, crater-filled ride for the next year or so. If you abhor ads on your web pages (like most people do), prepare for the terrifying reality that you can no longer hide them or prevent them from appearing. But then again, there's always Firefox. It makes me glad to be a Firefox user.

  • Firefox Translations: Client Side On-Demand Translations

    Move on over, Google Translate. Step aside, DeepL. There's a new kid in the translation neighborhood. Meet Firefox Translations. Unlike the other online translators out there (including the two already mentioned), Firefox Translations is a client-side translator. While the others are cloud-based, Firefox Translations translates the data in your browser on your local computer, so no information is ever transmitted to or from your computer during the translation. [...] Once a page is loaded in one of the supported languages (different from the language used on your computer), you should see the above toolbar in Firefox. Just click on the "Translate" button. If this is the first time you're using the tool for a particular language, it may take a few seconds to download the translation "dictionary" to your computer. It will then work to translate the page into your native language.
