Is it permissible for me to participate in a mixed-gender online programming course where interaction via audio and video is possible, with the likelihood of using unlicensed software, and what are the Sharia rulings governing this? Is it permissible to work in a field where one has learned through mixed-gender means or by using unlicensed software, and is the money earned from that considered permissible (halal)? And is it permissible for others to acquire knowledge from this person?

There is no objection to enrolling in the aforementioned educational course. Enrollment is not prohibited due to online mixing (ikhtilat) or doubts about using software without the owners' permission. It is obligatory to adhere to Islamic guidelines, such as lowering the gaze and refraining from speaking to foreign women (non-mahram) without necessity. The salary resulting from permissible work performed as required is lawful and is not prohibited simply because the education might contain Islamic transgressions.
