Looking forward to the conference in my backyard - #shmoocon - this weekend! My last conference was Hexacon, which was great, but I'm looking forward to a more diverse set of talks. Goals are to meet some more DC local hackers and win another Yeti from @ret2systems

New blogpost! I put together a thorough survey of security mitigations and architectures from the past few years.

Hardware solutions, software mitigations, and safe languages. CHERI, MTE, Rust, Swift, kalloc_type, Firebloom, GuardedMemcpy, CastGuard, and more! https://saaramar.github.io/memory_safety_blogpost_2022/

Survey of security mitigations and architectures, December 2022

@mpiedrav Hexagon DSP. Feels like pseudocode or even C

memcpy.S - arch/hexagon/lib/memcpy.S - Linux source code (v6.0.9) - Bootlin

Elixir Cross Referencer - Explore source code in your browser - Particularly useful for the Linux kernel and other low-level projects in C/C++ (bootloaders, C libraries...)

@chris_gammell do you recommend any devboards for this or the previous revision? They may just be focused on bigger customers
