Ask HN: Learning to Program...

So I know someone who has been a "programmer" for some time without an formal training. His limited knowledge is becoming a major problem as he is pretty much hitting a roadblock in his career. Would anyone recommend any resources (paid or not) for further training someone in both basic and advanced concepts in programming? He does not have the resources/time to go to a full 4-year college bachelor program at this point but is looking to get better.

Any help would be much appreciated.
