Here are some information about where the content from this website comes from and what you can do with it.
For now it is published under a classical “all right reserved” copyright: you are free to do fair quotes as long as you link to the source. Please avoid copying complete articles, instead link to the page: it will be nicer both for me and your readers as I try to regularly update my posts with new information.
Each title in my posts is a permalink to its section, making it easy to link to a particular section of a post.
For this website I tried to use images either in free of fair use.
If you are the right owner of an image on this site and are not happy how it is used, please contact me.
If you are looking for sources of free images, you can find a nice list on Wikimedia.
The nice wolf in the picture is a Hudson Bay wolf, a species native from the Canada.
They can sing too!
Most of the icons used on this website come from the openclipart website, completed with a few free material from Wikimedia Commons, Icon Archive, Icon Finder and freefavicon websites. As per my understanding these images are free at least for non-commercial use. Please refer to each website if you would like to reuse them.
I have to specially thanks dear_theophilus, Hopstarter (Jojo Mendoza), Moini and sixsixfive as several pictures I use have been made by them: people like you make the web more colorful and more beautiful!
I also use several icons from the Tango Desktop Project, uploaded on the openclipart website by warszawianka. You can also find a practical overview of these icons on Wikimedia Commons, here for the original icons, and here for the GNOME version.
Network diagrams are usually screenshots from GNS3 topologies.
Book covers, film posters, logos of company, products and projects are all the property of their legal owners. They are used here as what I consider to be fair use, for identification purposes, allowing the reader to easily recognize related posts or resources.
In addition, because an image often worth thousands words, I may sometime include illustrative images from various sources. If not directly in the post content, I usually tell the source of the image in its subtitle (click on the image to access its details).
In particular I regularly use xkcd comics: the author often manage to point real issue in a concise and satirical way, I like it!
