0x00 seems like it would also hide bugs since it's a common init. I like the Microsoft compiler approach in their debug builds: 0xCD = uninitialized but allocated heap space, 0xdd = freed memory, 0xcc = uninitialized stack variables. Weird values that jump out at you.

Watching Jason Donenfeld'd talk about the Linux kernel RNG. Really great talk about current status and future directions. Recommended for userspace authors looking at these issues. We worked with Jason as a community when finalizing arc4random in glibc. #linuxplumbers

Eroom's Law: "CPUs get 15% slower every year thanks to mitigations". With a bit of luck we'll all be able to run m68k, m88k, i960 and other interesting CPUs in a few years. Keep those Amiga's running!

If you're into operating system kernel random number generation, this document is a joy to read. zx2c4.com/projects/linux-rng… We've successfully catapulted the linux RNG into 2022! HT to Taylor and str4d, and hats off to Jason Donenfeld.
