Recently GitHub disabled the Rockchip Linux MPP repository, following a DMCA takedown request from the FFmpeg team. As of writing the affected repository remains unavailable. At the core of this issue is the Rockchip MPP framework, which provides hardware-accelerated video operations on Rockchip SoCs. Much of the code for this was lifted verbatim from FFmpeg, […]
Although flying well under the radar of the average Linux user, D-Bus has been an integral part of Linux distributions for nearly two decades and counting. Rather than using faster point-to-point interprocess communication via a Unix socket or such, an IPC bus allows for IP communication in a bus-like manner for convenience reasons. D-Bus replaced […]
With two cores at 240 MHz and about 8.5 MB of non-banked RAM if you’re using the right ESP32-S3 version, this MCU seems at least in terms of specifications to be quite the mini PC. Obviously this means that it should be capable of self-hosting its compiler, which is exactly what [Valentyn Danylchuk] did with […]
Key to efficient hardware emulation is an efficient mapping to the underlying CPU’s opcodes. Here one is free to target opcodes that may or may not have been imagined for that particular use. For emulators like the RPCS3 PlayStation 3 emulator this has led to some interesting mappings, as detailed in a video by [Whatcookie]. […]
To the surprise of almost nobody, the unprecedented build-out of datacenters and the equipping of them with servers for so-called ‘AI’ has led to a massive shortage of certain components. With random access memory (RAM) being so far the most heavily affected and with storage in the form of HDDs and SSDs not far behind, […]
In an excellent example of one of the most overused XKCD images, the libxml2 library has for a little while lost its only maintainer, with [Nick Wellnhofer] making good on his plan to step down by the end of the year. Modern-day infrastructure, as visualized by XKCD. (Credit: Randall Munroe) While this might not sound […]
When you start an STM32 MCU with its default configuration, its CPU will tick along at a leisurely number of cycles on the order of 8 to 16 MHz, using the high-speed internal (HSI) clock source as a safe default to bootstrap from. After this phase, we are free to go wild with the system […]
Although Robert F. Kennedy gets the credit for popularizing it, George Bernard Shaw said: “Some men see things as they are and say, ‘Why?’ I dream of things that never were and say, ‘Why not?’” Well, [Hadz] didn’t wonder why there weren’t many GPU debuggers. Instead, [Hadz] decided to create one. It wasn’t the first; […]
After you have written the code for some awesome application, you of course want other people to be able to use it. Although simply directing them to the source code on GitHub or similar is an option, not every project lends itself to the traditional configure && make && make install, with often dependencies being […]
