I think problems are hard when you are new to a domain. After you get some practice, nothing there is really that hard.

For me, the first hard thing was implementing this https://en.wikipedia.org/wiki/Dead-end_elimination#Generaliz...

Probably because it was the first algorithm I implemented with no reference implementation to look at.

The second hardest was a high performance proxy that can redirect to another proxy and can collect specific types of non-encrypted data.
