Cloud9 was acquired by Amazon Web Services (AWS) and they closed down the legacy version of Cloud9 (c9.io), that I use in the lectures.
While you can sign up for the new AWS version of Cloud9, that is not something that we recommend as it requires a credit card to use the free trial and is not exactly beginner friendly.
Instead, we now recommend using a different cloud based IDE called, GoormIDE.
Goorm is a great IDE and is fairly similar to the legacy version of Cloud9 that I use in the video lectures.
Everything that I mentioned in the previous video, regarding the use of Cloud9, can also be applied to Goorm.
Our TA (Ian) has created a readme file that explains the signup and setup processes for Goorm.
Once you finish with the instructions, then you can continue with the next section in the course.
Need help? Feel free to post in the Q&A or visit the #goorm-setup-help channel in our community discord server.
Please note, if you choose to install MySQL locally (explained in a later video), bear in mind that the mysql-ctl commands that I'll be using throughout the course do not apply to a local install of MySQL, they only work for GoormIDE.
Thanks,
