A lot of photographers will now video behind the scenes stuff to show them at work and have that ready for clients if questions arise. Also, during meetings (interviews) with potential clients invariably I'd talk through and show a collection of work that was similar to the types of problem the client was trying to solve. Might have been a wedding or a commercial shoot, I'd show them stuff that would solve what they needed and talk through with them. Similar things have happened with editing. I suppose an equivalent would be not just code but maybe wider community contributions. As I mentioned a portfolio goes beyond just 'code' or some 'product' that you made. It's there to sell 'you' so that includes things like bug fixing, visible issue solving, maybe mailing lists, maybe run a community platform, maybe clear contributions to open source projects or whatever. Anything you wnat I guess. It's relatively easy to become 'public' enough to be obvious who you are, or use some kind of cryptographic proof etc. There will be problems of due diligence, those are universal, but I think individuals and companies would both be better off if they took portfolios more seriously.
