- USDA PLANTS: Rosa nutkana C. Presl (plants.sc.egov.usda.gov)
Native Americans throughout the Pacific Northwest and Rocky Mountain region used Nootka rose as food, medicine, and for ceremonial purposes (Moerman, 2012). Hips of all wild roses are high in vitamin C and are made into jams, jellies, syrups and teas.
- Silicon reverse-engineering: the Intel 8086 processor’s flag circuitry (righto.com)
Status flags are a key part of most processors, indicating if an arithmetic result is negative, zero, or has a carry, for instance. In this post, I take a close look at the flag circuitry in the Intel 8086 processor (1978), the chip that launched the PC revolution.1 Looking at the silicon die of the 8086 reveals how its flags are implemented. The 8086’s flag circuitry is surprisingly complicated, full of corner cases and special handling. Moreover, I found an undocumented zero register that is used by the microcode.
- Rosa nutkana (Wikipedia)
Rosa nutkana, the Nootka rose, bristly rose, or wild rose is a 0.6–3.0-metre-tall (2–10-foot) perennial shrub in the rose family (Rosaceae).
