Documentation of software tools used in CS 240:
CS 240 Computing Environment
The CS 240 Computing Environment is available via:
- Remote access to the CS GNU/Linux server/workstations with one of:
- (Recommended) VSCode with the Remote Development extension; or
- Direct SSH access.
- The CS GNU/Linux workstations in the SCI L037 CS Systems Lab.
Installation of VSCode and first-time CS account setup are described in Assignment Zero.
If the recommended option is not working out for you, such as if you are not able to maintain a consistent network connection, there are other options for access to a CS 240 computing environment. (They require a little more setup or learning.) Please get in touch directly with your instructor if this is the case.
CS 240 code assignments require a CS 240 computing environment.
CS 240 code assignments are designed, tested, and graded in the CS 240 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 computing environment.
