  • NXP Continues Work On Linux Driver Bring-Up Of "Amphion" Video Encoder/Decoder - Phoronix

    NXP engineers continue persevering for bringing up a mainline-suitable, open-source kernel driver for their Amphion video encoder/decoder hardware. Out today is their 15th revision to the Amphion driver patches.

    The Amphion v15 driver patches were posted this morning for handling this video encoder and decoder found via the video (VPU) block with the NXP i.MX8Q platforms. Initially the IMX8QXP and IMX8QM SoCs are supported by this Amphion driver work.

  • A Pixel's Color & new documentation repository

    My work on Wayland and Weston color management and HDR support has been full of learning new concepts and terms. Many of them are crucial for understanding how color works. I started out so ignorant that I did not know how to blend two pixels together correctly. I did not even know that I did not know - I was just doing the obvious blend, and that was wrong. Now I think I know what I know and do not know, and I also feel that most developers around window systems and graphical applications are as uneducated as I was.

    Color knowledge is surprisingly scarce in my field it seems. It is not enough that I educate myself. I need other people to talk to, to review my work, and to write patches that I will be reviewing.

  • Initial Bits Land In Mesa 22.0 For Intel Raptor Lake - Phoronix

    In addition to Mesa 22.0 landing Vulkan 1.3 support today with the Radeon RADV and Intel ANV Vulkan drivers, Mesa today also received initial support for next-gen Raptor Lake S processors.

    With the in-development Linux 5.17 kernel there is the initial i915 kernel driver support for Raptor Lake S so now that the DRM/KMS side has initial RPL-S support, Mesa has landed its dependent support.

Arduino Projects: Sun and Power Trackers

  • This sun tracker uses an Arduino to increase solar panel efficiency | Arduino Blog

    With the rapid pace of solar panel installations over the course of the previous decade, there has been an ongoing challenge of trying to improve their efficiency. Apart from the typical silicon crystal photovoltaic cells, there are also more efficient/expensive cells known as concentration photovoltaics (CPV), which rely on a set of mirrors to focus sunlight into a small multijunction cell. Although this technology reduces the size and material requirements, it also requires precise sun tracking for peak performance. Ruediger Loechenhoff has been able to create a far cheaper solar tracker controller, which relies on an Arduino Uno to drive a set of two motors that position the panel. To achieve this, the Uno was connected to a 9-axis MPU-9250 compass module for internal positioning, a DS3231 real-time clock for accurate timing, and a DIY shading beam sunlight sensor to detect optimal angles. Operating the tracker is also quite simple since the firmware only requires an occasional calibration step after a set number of days.

  • This Arduino device can anticipate power outages with tinyML | Arduino Blog

    Our reliance on electronic devices and appliances has never been higher, so when the power goes out, it can quickly become an unpleasant and inconvenient situation, especially for those who are unable to prepare in time. To help combat this problem, Roni Bandini has devised a device he calls “EdenOff,” which is placed inside an electrical outlet and utilizes machine learning at the edge to intelligently predict when an outage might occur. Developed with the use of Edge Impulse, Bandini began by creating a realistic dataset that consisted of three columns that pertain to different aspects of an outlet: its voltage, the ambient temperature, and how long the service has been working correctly. After training a model based on one dataset for regular service and the other for a failure, his model achieved an excellent F-1 score of .96, indicating that the model can forecast when an outage might take place with a high degree of accuracy.

  • Do While – Loop Example in Python | Mark Ai Code

    Loops are an important and widely utilized element in all current programming languages. A loop is the finest solution for automating a certain repeated operation or preventing yourself from writing repetitive code in your projects. Loops are sequences of instructions that are executed repeatedly until a condition is fulfilled. Let’s take a closer look at how Python loops function.

  • Patch now: Zoom chat messages can infect PCs, Macs, phones with malware

    Zoom has fixed a security flaw in its video-conferencing software that a miscreant could exploit with chat messages to potentially execute malicious code on a victim's device. The bug, tracked as CVE-2022-22787, received a CVSS severity score of 5.9 out of 10, making it a medium-severity vulnerability. It affects Zoom Client for Meetings running on Android, iOS, Linux, macOS and Windows systems before version 5.10.0, and users should download the latest version of the software to protect against this arbitrary remote-code-execution vulnerability. The upshot is that someone who can send you chat messages could cause your vulnerable Zoom client app to install malicious code, such as malware and spyware, from an arbitrary server. Exploiting this is a bit involved, so crooks may not jump on it, but you should still update your app.

  • SAP attracts further criticism for Russia presence, despite promise to leave

    A Ukrainian minister has accused software giant SAP of continuing to operate in Russia despite the German vendor previously vowing to withdraw from the aggressor nation. In the months following Russia's invasion of Ukraine, SAP attracted criticism as it continued to support installations of its software in Russia and cloud services used by Russian businesses, including state-owned bank Sberbank.
