We've teamed up with the authors of Build It with Nitrogen to give you the chance to win a copy of their book. Not only that, we have one ebook to give away every month until the end of 2024 - that's one Erlang Forums winner each month!

About the prize

Build It with Nitrogen guides you, step-by-step, through the construction of highly reliable web applications using Erlang and the Nitrogen Web Framework. You walk through seven hands-on projects where each project builds on the last toward high-level competency - and you learn Erlang as you go. Nitrogen is "the fastest way to develop interactive web applications in full-stack Erlang" ...and so if you like the sound of that then this book may just be exactly what you're looking for!

How to enter

Every month, we will pick a random 6-digit Lucky Number which is displayed on our competition page for all to see. To enter the competition, all you have to do is log in via your Erlang Forums account and receive your weekly entry which is a randomly-generated entry number.

You can obtain a new entry number each week. At the end of the month, if any of your numbers turns out to be closest to that month's Lucky Number, you win!
