Article information and referencing
For any referencing style, you can use the following information:
For instance, to use with BibTeX:
@misc{copetti-xbox360,
url = {https://www.copetti.org/writings/consoles/xbox-360/},
title = {Xbox 360 Architecture - A Practical Analysis},
author = {Rodrigo Copetti},
year = {2022}
}
or a IEEE style citation:
[1]R. Copetti, "Xbox 360 Architecture - A Practical Analysis", Copetti.org, 2022. [Online]. Available: https://www.copetti.org/writings/consoles/xbox-360/. [Accessed: day- month- year].
Special use in multimedia (Youtube, Twitch, etc)
I only ask that you at least state the author’s name, the title of the article and the URL of the article, using any style of choice.
You don’t have to include all the information in the same place if it’s not feasible. For instance, if you use the article’s imagery in a Youtube video, you may state either the author’s name or URL of the article at the bottom of the image, and then include the complete reference in the video description. In other words, for any resource used from this website, let your viewers know where it originates from.
This is a very nice example because the channel shows this website directly and their viewers know where to find it. In fact, I was so impressed with their content and commentary that I gave them an interview 🙂.
Appreciated additions
If this article has significantly contributed to your work, I would appreciate it if you could dedicate an acknowledgement section, just like I do with the people and communities that helped me.
This is of course optional and beyond the requirements of the CC license, but I think it’s a nice detail that makes us, the random authors on the net, feel part of something bigger.
