For Project 1, you will be working with two Linux VMs. Your TA, Shyon, will lead two identical workshops to help you set up this environment:
Wednesday (2/12) | 1-3 PM @ HR411 Friday (2/14) | 1-3 PM @ HR411 Download the required files before attending the workshop, since the disk images are large files. If you have experience installing Linux on a VM, you may follow the provided instructions instead of attending. However, I recommend setting it up before the workshop. This way, if you encounter any issues, you can still attend for assistance. |
