Here are my solutions to the problem sets in the 6.0001 course at MIT. I watched the course videos at edX and the problem sets here were downloaded from the OCW website. There isn't much of a difference between OCW and edx's problem sets. I did see both ;)
The problem set 5 is incomplete. I think there is some problem with the given code - in function read_trigger_config(). If you can help me out, please do! However, I modified it to create a slightly different project that filters news feed only from Google News and does not use a triggers.txt file.
I decided to include the dates of when these were written in the code(I use Spyder) to not freak people(and future me!) out.
I also wrote a blog about my journey through this course.
If you have any doubts regarding the solutions, feel free to contribute or mail me at palashsharma891@gmail.com
