Checked the examples and Maxima still fails. It's even more disheartening that author mentions towards the end that had reported those issues years before they wrote the article. I had also used Maxima before and, though unsurprisingly found it less polished than Mathematica, got the job done without issues. But will probably refrain from recommending it. Would also like to see how other systems tackle those examples.
