Link not Working

Hi there, I tried to download the free E-Book on Greedy Algorithms, Divide & Conquer, and Dynamic Programming
but on clicking the image in https://dev.to/brandonskerritt/a-free-ebook-on-greedy-algorithms-divide-conquer-and-dynamic-programming-1712 I am getting a "Safari Can't Find on Server" error....
Also this link page.skerritt.blog/algorithms/ isn't working anymore....

Kindly upload that e-book, on subscribing to your mailing list too I am not able to get the e-book
