Someones link is down?

Hi @olso,
thank you for opening this issue, your article is awesome and I'm happy to add it to this list! 😄
I'll just ask you if you can add the year of the article inside round brackets at the end of the link, like the others. Just to maintain the consistency of the list, because we have also links of 3 years ago...
Don't worry about the broken link, I'll check it 😄
