A place for developers to talk about building on Farcaster.

Today I learnt that the Linux kernel has a feature called "Kernel Electric Fence" (KFENCE). KFENCE in Linux is a memory error detector that uses random sampling and CPU hardware to catch bugs with minimal performance impact. It's like having a highly efficient security guard that only checks a few packages but can still catch most smugglers, allowing for production-safe memory debugging. I don't know who needs to hear this but this is a super smart approach since it leverages the MMU of the CPU to trap invalid memory accesses, rather than relying on software instrumentation.
