Assets, scripts, project files and other downloadable materials that are linked at the end of each post are usually distributed under the MIT-License. Some assets from other people are included in some projects. All license information on the assets can always be reviewed by checking the LICENSE.txt which is present in every download.
I try to only included additional assets which are any of the Creative Commons licenses, MIT or public domain. This might not always be possible, so read the license file, if you want to use the assets in a commercial or public product or service. I assume no liability in the case of breach of a license by a user who has downloaded any assets, scripts or projects. It is your sole responsibility to check the LICENSE of the assets and make sure you apply them appropriately.
