- p1: shell implementation (
mumsh)- style: solo-project
- codebase: null
- evaluation: JOJ test required for correctness
- coverage: c-programing, string parsing, shell features, interprocess communication, IO, etc.
- p2: multi-threading database implementation (
Lemonion::lemonDB)- style: 1+2 team-project
- codebase: provided code template
- evaluation: JOJ test required for correctness and efficiency
- coverage: cpp-programming, string parsing, multi-threading, etc.
- p3: Minix3 scheduler implementation (
CoolZone::Minix3)- style: 1+2 team-project
- codebase: provided Minix3 source code
- evaluation: project demonstration required for functionality and performance
- coverage: c-kernel-programming, os debugging, scheduling, etc.
If there is similar course materials assigned in the future, it is the responsibility of JI students not to copy or modify these codes, or MD/PDF files because it is against the Honor Code. The owner of this repository doesn't take any commitment for other's faults.
