Disclaimer: The screencast is typically expected to go live before 13:25 of the course day, taking the setup time starting at 13:10 into account. The screencast goes live under the condition that our Kuai-Kuai responsibly keeps the laptop, digitizer, microphone, and internet working. If any of those cannot work (but we have some internet access), the TAs will notify the online audience on Slido/Discord, and a substitute recording (if there is one) will be uploaded after the class.
