Programming as a career change?

My sister-in-law has asked for my help about a possible career change.

Her current field is social science, and has a masters degree in politcal science, she's worked at NGOs and in acedemia and has recently moved into a marketing/communications company where she isn't overly happy.

She asked me for advice on how to retrain as a programmer, she likes the idea of one day being a "digital nomad" (as she is in her early 30s and has no real ties to the place where she lives).

As she speaks multiple languages and has a good eye for design I think she'd be good as a technical person who can interact with customers and use her social science background to her advantage.

She is interested in web-development (but has no experience at all) so I suggested that she should first participate in some sort of self-study UNIX course, and then move on to a scripting language of some sort.

Does anyone else have any good advice that may help her?

Thanks for the comment, I'm a long time UNIX user (since the early 90s) and because I see the majority of web-applications running on *NIX systems, I, personally think a grounding in UNIX is quite important. I could be wrong though, so I'm all ears to any suggestions for her.

I'd suggest an online course or bootcamp. Not because graduates of these courses are immediately employable (they're not), but to get an overview of what needs to be learned to be a web developer, and how much interest and aptitude she has. After that, I'd recommend a deeper dive into whatever aspect most interest her, in order to develop employment-ready skills.
