I was told that being an ACM member was good. U have access to a whole lot of stuff. However, I did not not know that it was that good!!! I registered a week ago (for developping countries it’s only $43) and the wealth of up-to-date information available is absolutely amazing.
So many papers and course notes!!! It’s an absolute must-have if you want to keep up-do-date about what people are researching in computing, if you want to start good research or provide up-to-date material to students.
The only drawback is that there’s too much exciting stuff to read 😉
