Home » content Free Software or Openwashing Leftovers Submitted by Roy Schestowitz on Tuesday 10th of May 2022 11:03:32 PM Filed under Software WWF Launches Open-Source App To Make Food Supply Chains More Transparent The World Wildlife Fund (WWF) has launched an app that aims to help food supply chains become more transparent. The transparenC app (available for both Android and iOS devices) and web portal is the world’s first open-source traceability software for any kind of food supply chain. It can be used anywhere by farmers, buyers and retailers without paying licensing fees to ensure transparency and accountability across all stages of food production.

The FSFE provided input by publishing an open letter demanding the right to install any software on any electronic device. This right would allow to keep our devices longer, but it requires manufacturers to follow certain rules. For example, manufacturers must be required to unlock bootloaders on all devices, including computers, tablets and phones; they must also publish full specifications for every component on the device. This allows us and any third party to better repair our devices, and even reuse parts of them. The use of Open Standards is also necessary for devices to communicate and operate with each other. Initially 38 organisations agreed on the necessity of these conditions and signed the open letter before publication. It is still possible to sign the letter and more than 45 organisations have now signed. It speaks volumes that tech companies, right to repair initiatives, and important environmental organisations support the right to install any software on any device.

Annual Report: TDF’s (The Document Foundation) infrastructure in 2021 So I enabled support for up to 16384 columns in Calc by default some time ago, but just getting it to work was not necessarily the end of the work. Making Calc have 16 times more columns means that any operation that works on entire columns is suddenly 16 times slower, or even worse. Similarly this could easily lead to 16x more memory used. So the support not only needs to work, but it also needs to be usable. It theory adding a number of empty columns to the end of a spreadsheet should not make a difference, but in practice it does. With 1024 columns it is not as necessary to ignore those empty columns as it is with 16k, and a lot of the code dates back to the times when Calc supported even fewer colums (256?), where a being little inefficient here or there didn't show. But now it suddently did. For example, if you protect or hide all unused columns until the end of the spreadsheet, then hitting the right arrow key on the last accessible cell makes Calc check all cells to the right for whether it's possible to go into them. And checking whether a column is hidden requires searching the list of column information, which is not trivial (it's compacted in order not to waste memory). The barely noticeable cost of this with 1024 columns got large enough to cause noticeable delays. Fortunately the ColHidden() function is smart enough to return the first and last column in the compacted range where the flag is equal, the code doing the cursor navigation just up until now didn't bother using that information, but now it needed to do so. Raspberry Pi Reptile Cam Monitors Lizards for Optimal Support There’s nothing quite like the love little critters bring into our lives, but it’s not always easy to ensure their environment is fully optimized for their needs. That’s where maker Jamie Munro’s reptile cam project comes into play. With the help of a Raspberry Pi, he’s able to monitor his pet lizards in real-time and track important factors that can impact their well-being. This isn’t Munro’s first foray into the world of microelectronics. In fact, he has a website that doubles as a portfolio showcasing a broad history of both microelectronics and programming projects that back up the level of quality seen in this reptile cam project. The reptile monitor system consists of a web-based GUI that provides live stats about their environment as well as a live video feed of the enclosure. It relays information such as current temperature, humidity levels, and even has options to configure power outlets connected to things they use like heaters and lights.

Headlining additions in the 9.5 update include support for immutable data in Microsoft Azure, a new Debian Linux virtual appliance for managing Zerto and support for Google Cloud Platform storage. Graphics Hacking by Rosenzweig and Kristóf Rosenzweig – The Apple GPU and the Impossible Bug In late 2020, Apple debuted the M1 with Apple’s GPU architecture, AGX, rumoured to be derived from Imagination’s PowerVR series. Since then, we’ve been reverse-engineering AGX and building open source graphics drivers. Last January, I rendered a triangle with my own code, but there has since been a heinous bug lurking: The driver fails to render large amounts of geometry. Spinning a cube is fine, low polygon geometry is okay, but detailed models won’t render. Instead, the GPU renders only part of the model and then faults. [...] Traditional immediate mode renderers render directly into the framebuffer. They first run the vertex shader for each vertex of a triangle, then run the fragment shader for each pixel in the triangle. Per-vertex “varying” data is passed almost directly between the shaders, so immediate mode renderers are efficient for complex scenes. There is a drawback: rendering directly into the framebuffer requires tremendous amounts of memory access to constantly write the results of the fragment shader and to read out back results when blending. Immediate mode renderers are suited to discrete, power-hungry desktop GPUs with dedicated video RAM. How mesh shaders are implemented in the driver | Timur’s blog In part 1 I gave a brief introduction on what mesh and task shaders are from the perspective of application developers. Now it’s time to dive deeper and talk about how mesh shaders are implemented in a Vulkan driver on AMD HW. Note that everything I discuss here is already available as public information in open source driver code. The goal of this blog post is to elaborate on how mesh shaders are implemented on the NGG hardware in AMD RDNA2 GPUs, and to show how these details affect shader performance. Hopefully, this helps the reader better understand how the concepts in the API are translated to the HW and what pitfalls to avoid to get good perf.
