- The abandoned building at 1375 Frost Avenue is probably the oldest building in Maplewood. It was constructed in 1879 near the north end of Lake Phalen “to hold elections and transact all business connected with the town” (New Canada Township). The town government was led by three supervisors who were elected every year and most of the business in early years was to create and maintain roads and bridges. As the population grew, a more central location was needed and the building was moved to the south side of Frost Avenue in 1900.
- Reverse-engineering the multiplication algorithm in the Intel 8086 processor (righto.com)
While programmers today take multiplication for granted, most microprocessors in the 1970s could only add and subtract — multiplication required a slow and tedious loop implemented in assembly code. One of the nice features of the Intel 8086 processor (1978) was that it provided machine instructions for multiplication, able to multiply 8-bit or 16-bit numbers with a single instruction. Internally, the 8086 still performed a loop, but the loop was implemented in microcode: faster and transparent to the programmer. Even so, multiplication was a slow operation, about 24 to 30 times slower than addition.
