LGTM, thanks for the great article.

I made some changes:

1. I add a co-author called databend, then move the advertising into the profile page of databend.
2. Some picture is blurry, I replaced them with an urlpreview block. However, other blurry pictures should also be replaced with high-resolution ones, such as cargo nextest.

Thanks. I updated it.
