  • Tackle The Monkey: Raspberry Pi Gets Round Screen | Hackaday

    You could argue that the project to add a round screen to a Raspberry Pi from [YamS1] isn’t strictly necessary. After all, you could use a square display with a mask around it, giving up some screen real estate for aesthetics. However, you’d still have a square shape around the screen and there’s something eye-catching about a small round screen for a watch, an indicator, or — as in this project — a talking head.

    The inspiration for the project was a quote from a Google quote about teaching a monkey to recite Shakespeare. A 3D printed monkey with a video head would be hard to do well with a rectangular screen, you have to admit. Possible with a little artistry, we are sure, but the round head effect is hard to beat. Honestly, it looks more like an ape to us, but we aren’t primate experts and we think most people would get the idea.

  • Move! makes burning calories a bit more fun | Arduino Blog

    Gamifying exercise allows people to become more motivated and participate more often in physical activities while also being distracted by doing something fun at the same time. This inspired a team of students from the Handong Global University in Pohang, South Korea to come up with a system, dubbed “Move!,” that uses a microcontroller to detect various gestures and perform certain actions in mobile games accordingly.

    They started by collecting many different gesture samples from a Nano 33 BLE Sense, which is worn by a person on their wrist. This data was then used to train a TensorFlow Lite model that classifies the gesture and sends it via Bluetooth to the host phone running the app. Currently, the team’s mobile app contains three games that a player can choose from.

  • Matthew Garrett: Boot Guard and PSB have user-hostile defaults

    Compromising an OS without it being detectable is hard. Modern operating systems support the imposition of a security policy or the launch of some sort of monitoring agent sufficient early in boot that even if you compromise the OS, you're probably going to have left some sort of detectable trace[1]. You can avoid this by attacking the lower layers - if you compromise the bootloader then it can just hotpatch a backdoor into the kernel before executing it, for instance.

Review: instantOS Beta

A project that has been sitting on the DistroWatch waiting list for several months is instantOS. The instantOS project is currently in its beta stage of development, but has been around long enough to review and it claims to offer a number of intriguing features. instantOS is based on Arch Linux and strives to be both light and fast. The distribution's website reports instantOS requires less than 200MB of RAM. The project also ships with its own graphical environment. This custom environment is called instantWM and it reportedly offers both tiling and floating window management. This window manager seems to be the centre piece of the distribution. instantOS is available in a single edition for x86_64 computers and is provided through a 1.4GB download. Booting from the downloaded media brings up a menu which offers options for booting into "Arch Linux". Booting into instantOS brings up a graphical environment. A thin panel is placed across the top of the screen. This panel provides access to an application menu, nine virtual desktops, a clock, and system tray. Shortly after the window manager loads we're presented with a welcome application which looks just like a simple drop-down menu. This menu lists a handful of options, including Get Started, Install, Documentation, Settings, GitHub, Support, and Close. Read more
