Install Node on your computer, run npm install -g yarn, and then run yarn. To format code, use the yarn prettier command, which will automatically format all .md and .html files. There is also a GitHub Action to format code which can be dispatched manually.The cs161 user is using UnicornBox to store a file called ip.txt. cs161 is a special-purpose account on UnicornBox. It uses a separate login mechanism, so you won’t be able to log in as cs161, but you may still be able to change some of its files. Your task: Change the contents of cs161 user’s ip.txt file to be 161.161.161.161.The backend for this project exclusively uses single quotes for SQL queries. It is possible to select constants in SQL rather than selecting column names. For example, SELECT 1, 'foo', 'evan' will return a single row with 3 columns, with values of 1, 'foo' and 'evan'. You may find this useful if you can guess the format of the rows being ...
