In this edition of our open source news roundup, we take a look at new features for Raspbian, Wireguard and Linux kernel, free Python course from the NSA and more!
For this week’s blog, I turn to a desktop activity that I use fairly frequently. It’s screen capturing – offering the ability to share images on my computer screen with a colleague or friend. Recording a video or screencast might be snazzier, but a still-image screen capture, known as a screenshot, is often all I need to get the message across.

Gumstix has added to its line of Raspberry Pi add-on boards such as its Stepper HAT […]
A glaring omission from my RPI4 blog to date is gaming on this wee machine. There’s so many games to play on the machine, it’s difficult to know where to begin. I’ll start with something that shouldn’t be taxing on the machine. Emulating home computers. Specifically, the Amiga, ZX Spectrum, and Atari ST. They were hugely popular home computers targeted heavily towards games, but also ran other types of software.
On Kickstarter: a “Sania Box Embedded Computer Kit” for STEM education developed by 13-year old Sania Jain that combines a Raspberry Pi 4 with a kid-friendly, sensor-equipped add-on board and Python coding lessons. Despite continual efforts by the Raspberry Pi Foundation to remind us, it’s easy to forget that the ubiquitous Raspberry Pi was launched […]
Are you just getting started with machine/deep learning, TensorFlow, or Raspberry Pi? I created rpi-deep-pantilt as an interactive demo of object detection in the wild, and in this article,?I'll show you how to reproduce the video below, which depicts a camera panning and tilting to track my movement across a room.
The Raspberry Pi Foundation announced today that it has started working on implementing support for the open-source Vulkan graphics API for their Raspberry Pi single-board computers.
In Linux, every program and daemon is a "process." Most processes represent a single running program. Other programs can fork off other processes, such as processes to listen for certain things to happen and then respond to them. And each process requires a certain amount of memory and processing power. The more processes you have running, the more memory and CPU cycles you'll need. On older systems, like my seven-year-old laptop, or smaller computers, like the Raspberry Pi, you can get the most out of your system if you keep an eye on what processes you have running in the background.
There are 3 models of the Raspberry Pi 4 (RPI4) available. They are identical except for the amount of RAM onboard; choose from 1GB of RAM, 2 GB of RAM, or 4GB of RAM. There’s no way of upgrading the RAM once a user has made their purchase. So it’s pretty important to choose the model that best fits your requirements, or you may end up spending more than necessary, or even need to buy extra RPI4’s. For this week’s blog, I’m seeking to provide information that’ll help you determine which model of the RPI4 to get.
Given the multimedia strengths of the RPI4, I’ve spent a few weeks covering video streaming, then examining the viability of the RPI4 to play locally stored video, before turning to examining the RPI4 as a home theater. Continuing this theme, for this week’s blog I look at the RPI4 as a screencaster.

Piwheels automates building Python wheels (pre-compiled Python packages) for all of the projects on PyPI, the Python Package Index, using Raspberry Pi hardware to ensure compatibility. This means that when a Raspberry Pi user wants to install a Python library using pip, they get a ready-made compiled version that's guaranteed to work on the Raspberry Pi. This makes it much easier for Raspberry Pi users to dive in and get started with their projects.
Historically and theoretically speaking, a decade, a century, or a millennium starts when the clock turns midnight on January 1 of the year one of its decimal order. For example, the 20th century started on January 1, 1901, not on January 1, 1900. The reason for this is simple: there is no year 0 in our modern calendar, so these periods of time start on year 1 (using the Gregorian calendar). But that's not how we refer to time periods colloquially and culturally; for example, when we mention '80s music or movies, we're talking about the period from 1980 to 1989.
For this week's blog, I’m looking at straightforward video playback from locally stored media. Does the RPI4 have sufficient grunt to be a capable video player?

Joe's Window Manager (JWM for short) is a lightweight window manager for X11. It's written in C, minimally using Xlib. Because it's so small and simple, JWM makes a great window manager for slow or old computers. The Raspberry Pi barely registers that JWM is running, leaving precious system resources for more important tasks than the desktop.
I’ve received a few requests to see how the RPI4 fares as a remote desktop client. I can see this could make sense. The RPI4 offers dual monitor support. It should have sufficient CPU and GPU resources to act as a functional remote desktop, particularly when connecting to servers that have better system resources.
Radxa’s Dual ($25) and Quad ($35) SATA HATs work on the Raspberry Pi 4 or Rock Pi 4 at up to 400 MB/s via USB 3.0. There’s also a faster, 800 MB/s $49 “Penta SATA HAT” for the Rock Pi 4 that uses PCIe to support 5x drives. You can find a few SATA HATs […]
