Is it me or is there a bug with pointers on the bottom of http://www.pjhutchison.org/tutorial/pointers.html ?

Agree, it's broken. It's also assigning string literals to char array struct members in a non-initializing context, which doesn't work. As someone trying to piece together C knowledge from various b0rk3n tutorials (as a pre-Internet teenager in the early 90s) it's pretty provocative. Luckily I healed and levelled up since.

Reminds me a bit of the "Mastering C Pointers" book that was popular in the early 90s and contained a multitude of outright errors.

Out of curiosity, why would one want to learn programming for AmigaOS today?

It is a complex, non-trivial operating system which has its merits in terms of design and prudent use of resources. All of this is well-documented and understandable. You can learn how everything works, top to bottom and back again, which is a feature modern operating systems tend to have lost over the years. I would also argue that it is a humane design, meant to be understood.

You might have the money to buy an Amiga now?

Fact is, with a little LCD and a nice keyboard, one could put the Amiga in the 'loo and have a fair bash at the old school while pushing one out, eh .. ?
