This is my new trailer video for the channel. No need to watch if you are a regular viewer. Just a note about ads on these videos. I normally put an ad at the beginning of my videos, and sometimes at the end as well. This is essential to generate some funds for the channel and my educational projects. However, I never put ads in the body of the video, no matter how long it is. This means that once you have started to watch the video, you can watch the whole thing without any interuptions.
