> While Microsoft and Apple don’t release the source code for their operating systems, a good estimate is that it takes around 50 million lines of code to run these software behemoths. The Linux kernel alone holds around 30 million lines, with systemd containing over one million lines on its own, which doesn’t include estimates for the desktop environment or other parts of a standard installation. But millions of lines of code, or even hundreds of thousands, aren’t necessary for building a fully functioning operating system. This one sets up a complete OS in exactly 2000 lines of code.
> The ability to change direction without turning is the specialty of omnidirectional wheels, which [maker.moekoe] used to their full potential on a pair of ESP32-controlled robots. Video after the break.
> Insight into a project and resources to teach data literacy and data science skills to primary school learners, from a research team in Scotland.
> To sum it up: Raspberry Pi is currently a 'Strategic Member' of RISC-V International, and they are working on multiple custom silicon designs—we've already seen their RP3A0 SiP chip and the RP2040, and they surely have more in the pipeline. Eben said currently there are no plans to move the Raspberry Pi SBC to RISC-V due to the lack of high-performance 'A-class' cores, but "never say never" when it comes to RISC-V architecture finding its way into a future Pi microcontroller.
> YouTuber Jeff Geerling recently flew over to the UK to sit down with Raspberry Pi CEO Eben Upton for a chat about shortages, predictions, the Raspberry Pi Pico and other hot topics. The short of it is that stock levels are improving, close to Upton's 2022 prediction and that we are now seeing better stock levels than 2022 as Raspberry Pi slowly catches up with the backlog. Upton explained the reasoning behind prioritizing OEM customers over consumers, and addresses some of the negativity that was levied on Raspberry Pi by a minority of the passionate and vocal community.
> The video starts with Geerling candidly explaining that his trip to the UK was not funded by Raspberry Pi, rather it was funded via sponsorship and Patreon supporters. With that out of the way Geerling covers a series of topics with Upton, and we've been through the video and pulled out the key points, with timestamps for you to listen to.
> Tristam used a Raspberry Pi 3B+ for this project, but there’s no reason you couldn’t use a Raspberry Pi 4 B in its place. To test the configuration, Tristam connected his Raspberry Pi to a Ubiquiti AC long-range wireless access point using the Pi’s onboard Wi-Fi support. Although this worked for his demonstration, you could easily connect the Pi to the internet using other sources like an Ethernet connection.
> The senior care facility where Hayden works already had a system for tracking each resident room with a PIR (passive infrared) sensor. But that system was no longer functional and wasn’t serving any purpose. Instead of buying a whole new system, Hayden chose to tap into the existing sensors. To do that, they used five Arduino Mega 2560 boards to create hub units. Those hubs were spread around the building and each one monitors the PIR sensors from a handful of rooms.
