- The United Arab Emirates (UAE) invests in a strategy to paint the country as progressive, tolerant, and rights-respecting while carrying out its zero-tolerance policy toward dissent. Many activists and dissidents remain detained, particularly those incarcerated in relation to the “UAE94” case, for exercising their rights to free expression and association. UAE-based migrant workers face widespread abuses, including escalating climate risks, and these abuses contribute to climate injustice in multiple ways.
- Inside the 8086 processor’s instruction prefetch circuitry (righto.com)
The groundbreaking 8086 microprocessor was introduced by Intel in 1978 and led to the x86 architecture that still dominates desktop and server computing. One way that the 8086 increased performance was by prefetching: the processor fetches instructions from memory before they are needed, so the processor can execute them without waiting on the (relatively slow) memory. I’ve been reverse-engineering the 8086 from die photos and this blog post discusses what I’ve uncovered about the prefetch circuitry.
