Geo Carncross presents kOS, a tiny graphical operating system written in k, C, and assembly that achieves a 90-kilobyte binary by eliminating code bloat through minimalist design. The system includes a programming language (k), database (kdb), and graphical interface, demonstrating that redundancy-free code can be achieved in large systems through careful architecture and readability-focused programming practices.
A developer asks about learning Q/KDB+, working as a Q/KDB+ developer, current market conditions, career prospects, and whether finance is the only major industry using this technology.
