Delete the timetable system by mistake

It took a day and a half to crawl the curriculum at the dean's Office, and the results were mistakenly deleted this evening while playing git. It's so stupid. The academic office of the Beihang University selected course is click on the radio button, and finally do not show to people in the form of a timetable. So by logging in, visiting the Web, using Jsoup to parse the course And in a more beautiful form to show. Where the login module to verify code cracking, only need to enter the user name and password, the verification code automatically input, submit this form on the landing success. However, I have deleted this code and will restore it tomorrow.

So there is sigh, the ancients taste the cloud, do not use the RM instructions easily unless you know exactly what you are doing. When you are tired, you must not engage in dangerous movements. What is a dangerous action? Delete, modify, and so on can not restore the write operation is dangerous action. I'm deleting a. The result was that B was deleted. The mistake of delete is not done one or two times, must learn lessons, cautious use RM instruction.
