[$] Giving Rust a chance for in-kernel codecs

Video playback is undeniably one of the most important features in modern consumer devices. Yet, surprisingly, users are by and large unaware of the intricate engineering involved in the compression and decompression of video data, with codecs being left to find a delicate balance between image quality, bandwidth, and power consumption. In response to constant performance pressure, video codecs have become complex and hardware implementations are now common, but programming these devices is becoming increasingly difficult and fraught with opportunities for exploitation. I hope to convey how Rust can help fix this problem.

[$] Support for the TSO memory model on Arm CPUs

At the CPU level, a memory model describes, among other things, the amount of freedom the processor has to reorder memory operations. If low-level code does not take the memory model into account, unpleasant surprises are likely to follow. Naturally, different CPUs offer different memory models, complicating the portability of certain types of concurrent software. To make life easier, some Arm CPUs offer the ability to emulate the x86 memory model, but efforts to make that feature available in the kernel are running into opposition.
