Questions & Answers

Q: What makes a programmer a "real" programmer?

A real programmer is someone skilled in low-level coding and is not afraid to use go-to's or modify binary code directly to achieve their desired outcomes. They have an intimate understanding of computers and can work at the hardware level.

Q: What was the role of Mel Kay and what did he accomplish as a programmer?

Mel Kay worked for an early computer manufacturer in the late 1950s. He demonstrated real programming techniques and created a program to play pontoon or 21 blackjack, showcasing the capabilities of the new computer at shows and for customers.

Q: What was the earliest form of memory in computers?

The earliest computers did not have conventional memory like magnetic cores or hard disks. Instead, they used drum memory, which involved a drum with fixed heads positioned over tracks. It offered minimal latency as the heads were always positioned over the data.

Q: How did programmers optimize the use of drum memory?

Real programmers would strategically position instructions on the drum to minimize seek time and maximize program speed. By determining the time it took for an instruction to execute, they could position subsequent instructions for efficient processing.

Summary & Key Takeaways

• The content explores the story of a real programmer named Mel Kay who worked for an early computer company and used unconventional methods to make machines work.

• In the early days of computers, drum memory was used as the first form of commercial storage, with fixed heads and the ability to position instructions strategically.

• The video also discusses how real programmers maximize the speed and efficiency of computers with limited storage and the importance of speed in early computer systems.
