First of all, this entire discussion is kind of a moot point because that question is closed: the question itself is not something that will lend itself to long term constructive posts. It's basically a current resource request.
That being said, for future reference:
Some self promotion is allowed on the SE network as long as answers also provide valuable content that will stand the test of time. For example this answer would be fine:
You can do that with a code construct like this:
This arrangement solves your problem because...
This is the solution I've implemented in library X which you can checkout if you want a pre-built implementation of this.
That we can handle. Note that this actually answers the question and explicitly reveals the users connection to the product being advertised. Without the part of the answer that actually answers the question, it wouldn't be tolerated:
You can do this easily with library X, get it here.
Note this doesn't actually answer a question or reveal the affiliation. This is unwanted.
