- The 80-acre Devils Lake NRCA contains a 22-acre lake, wetland, and sphagnum bog system, including 12 acres of open water, 6 acres of marsh and swamp, and 4 acres of quaking sphagnum bog. The forested area surrounding the lake has survived numerous fires and developed old growth characteristics, with a diversity of age classes and species, a layered canopy, and abundant snags and large downed logs.
- Reverse-engineering the ModR/M addressing microcode in the Intel 8086 processor (righto.com)
One interesting aspect of a computer’s instruction set is its addressing modes, how the computer determines the address for a memory access. The Intel 8086 (1978) used the ModR/M byte, a special byte following the opcode, to select the addressing mode.1 The ModR/M byte has persisted into the modern x86 architecture, so it’s interesting to look at its roots and original implementation.
