Documentation of software tools used in CS 240:
CS 240 GNU/Linux Computing Environment
The CS 240 GNU/Linux Computing Environment is available via:
- Local access to the CS GNU/Linux workstations in the SCI L037 CS Systems Lab.
- Remote access to the CS GNU/Linux server/workstations with one of:
- VSCode with the Remote Development extension; or
- Direct SSH access.
Account and tool setup are described in Assignment Zero.
CS 240 code assignments require a CS 240 GNU/Linux computing environment.
CS 240 code assignments are designed, tested, and graded in the CS 240 GNU/Linux computing environment, since low-level system details matter in this course. We guarantee support (help with provided tools) and consistency (our grading and your testing use the same environment) only for work in a CS 240 GNU/Linux computing environment.
