- Very early C compilers and language (cm.bell-labs.co)
Several years ago, Paul Vixie and Keith Bostic found a DECtape drive, attached it to a VAX, and offered to read old DECtapes. Even at the time, this was an antiquarian pursuit, and it presented an opportunity to mine beneath the raised floor of the computer room and unearth some of the DECtapes we’d stored since the early 1970s. Gradually, I’ve been curating some of this, and here offer some of the artifacts. Unfortunately existing tapes lack interesting things like earliest Unix OS source, but some indicative fossils have been prepared for exhibition.
- Archimedes (Wikipedia)
Archimedes of Syracuse (/ˌɑːrkɪˈmiːdiːz/ AR-kim-EE-deez; c. 287 – c. 212 BC) was an Ancient Greek mathematician, physicist, engineer, astronomer, and inventor from the ancient city of Syracuse in Sicily. Although few details of his life are known, he is regarded as one of the leading scientists in classical antiquity. Considered the greatest mathematician of ancient history, and one of the greatest of all time, Archimedes anticipated modern calculus and analysis by applying the concept of the infinitely small and the method of exhaustion to derive and rigorously prove a range of geometrical theorems. These include the area of a circle, the surface area and volume of a sphere, the area of an ellipse, the area under a parabola, the volume of a segment of a paraboloid of revolution, the volume of a segment of a hyperboloid of revolution, and the area of a spiral.
