Please could you help me license my website. I want the code, images, videos, audios, writings to be in CC by SA, it is a page that I plan to upload to Github.

I heard that the code should not be licensed in CC by SA. If that is true, I will license my code in the GPL.

I want to know if to do the above it is enough to place this at the end of all the pages:
This work by creator is licensed under CC BY-SA 4.0

I usually look to Pixabay and Open verse first. Any suggestions? I usually go with CC0 to avoid any issues or sourcing.

Just looks like an ugly steel box but it is a NAAC/aircrete (aircrete is a lightweight type of concrete) mixer designed for homebuilders anywhere to build with aircrete, efficiently, at relatively high volume.

The mixer I designed uses go kart engines, v-belt pulleys and is exceedingly low tech but uses basic mixing techniques used in industry.

The economics regarding aircrete border on the unbelieveable, especially in the developing world where the Portland cement price is very low.

I plan on releasing the design and an operation video next week and could use some advice on achieving my goal of keeping it open source. I need help in several areas and my DM's are open. I already called and emailed CC and got a form reply only.

Is the use of pictures unter CCL already considered as “commercial use” if it is just for an internal meeting?
