- Why did x86 support self-modifying code in the 80s and 90s? (stackexchange.com)
On the simplest microprocessors, self-modifying code is not a special problem. On an 8080, you can write just ahead of the instruction pointer, and a few clock cycles later, the instruction you just wrote, will be fetched and executed as though it had been there all along. But as pipelines and instruction cache are introduced, this becomes more problematic.
- Jamaica (Wikipedia)
Jamaica (/dʒəˈmeɪkə/ jə-MAY-kə; Jamaican Patois: Jumieka [dʒʌˈmie̯ka]) is an island country in the Caribbean Sea and the West Indies. At 10,990 square kilometres (4,240 sq mi), it is the third-largest island—after Cuba and Hispaniola—of the Greater Antilles and the Caribbean. Jamaica lies about 145 km (78 nmi) south of Cuba, 191 km (103 nmi) west of Hispaniola (the island containing Haiti and the Dominican Republic), and 215 km (116 nmi) southeast of the Cayman Islands (a British Overseas Territory).
