I love getting my father to watch things like this. He was born in the 30s and entered the police force after a stint in the RAF (late 1950s). It's good to get him ranting about the historical inaccuracies in it (ranks that didn't exist at the time, etc). Makes it much more entertaining.
A part of the Foyle's War I found interesting were the back-themes. They didn't hide the normally unspoken events (anti-Italian riots, rampant antisemitism, defeatism, black-marketing). The part of the home front they'd rather be forgotten.
It adds to the main thread's context; sometimes even setting up context for episodes yet to come.
The sandsifter audits x86 processors for hidden instructions and hardware bugs, by systematically generating machine code to search through a processor's instruction set, and monitoring execution for anomalies. Sandsifter has uncovered secret processor instructions from every major vendor; ubiquitous software bugs in disassemblers, assemblers, and emulators; flaws in enterprise hypervisors; and both benign and security-critical hardware bugs in x86 chips.
Also interesting how he reduces the possible number of instructions from 1.3x1036 to about 100,000,000 by storing them across page boundaries for execution where the second page is marked as not executable. He then shifts the max. 15 byte long instruction left until no fault is generated.
Lastly, a so-called ‘halt and catch fire’ instruction was discovered on an as-yet unnamed x86 processor. This instruction, executed in ring 3 from an unprivileged process, appears to lock the processor entirely
That could be bad..
