I am Cheng Zheng
Programmer & Designer of this website.
I hope this website save you some time.
btw, if more people use this, more Sum Up there are, More time will be saved.
If you like this website, I hope you can tell your friend. (on Facebook or Twitter maybe)
( This is my personal project, this website does not belong to Google )
( Youtube belongs to Google, in case you don't know)
Why I create this?
I watch a lot Youtube educational long video (normally 45+ minute)
like data structure & algorithem by some university, or sometime physics or some other topic I think interesting
and often feel frustrating and wasting time
I believe many people feel the same.
because there are always part of video is useless.
The teacher talk about when is final, how many mark they should get, how many TA, blahblah
I really hope after I create this tool
people would use it to sum up what part is useless part,
so people after them can save time
"please skip first 5 minute, that is intro TA and how many exam and when should came to class( monday,thursday,8:30am) the MAIN part start at 05:31, this course mainly about....."
"Please skip this entire Lecture 2.
This lecture is more about philosophy and general intro, Instead of really talk about data structure & algorithem, the teacher talk about what is SCIENCE is computer science, how people classify thing, what is science, and use analogy like tree, rack, element. *completely waste of time* "
- help you skip useless part
- know what this course is about before you spend solid 45+ minute to watch it
That's why I build this.
