What surprised me was that this entire walk is fully hardware-driven -- no microcode involvement at all. The state machine reads the page directory entry, reads the page table entry, checks permissions, and writes back the Accessed and Dirty bits, all autonomously. Since it's hardware-driven, it runs in parallel with the microcode and needs its own memory bus arbitration -- the paging unit must share the bus with both data accesses from the microcode and prefetch requests from the instruction queue.
If you're seeking a scary story where no good deed goes unpunished, then you'll appreciate Crazy Old Lady. Written and directed by Martín Mauregui, this horror movie begins with a relatively mundane phone call. A woman is on the line with her elderly mother, Alicia (Carmen Maura), whose dementia keeps throwing them into a frustrating conversational loop. Not able to go check on her mom, she calls on an ex-boyfriend named Pedro (Daniel Hendler) to go by the house. Far from a feeble old woman living in fear, Alicia is fired up with a wicked scheme of her own.

"Tuning frictional behavior on the fly has been a long-standing engineering dream," said co-author Katia Bertoldi of Harvard University. "This new insight into how surface geometry governs slip pulses paves the way for tunable frictional metamaterials that can transition from low-friction to high-grip states on demand.” In addition, the dynamics revealed by these results are similar to those of tectonic faults and thus give scientists a new model for the mechanics of earthquakes, according to their new paper published in the journal Nature.
