Are you sure that's an induction element? Induction elements don't get hot, only the pan does. Easy way to tell is - does the element switch only turn on when a pan is on top of it?
I'm the author of this tutorial, crazy to see it linked here 20yrs after I wrote it. It was an assignment for 400-level COSC at Otago, everyone in the class had to write a tutorial on something and then present it. The department just happened to post them on their website.
Crazily, this tutorial must have filled a niche because I still get people contacting me about it, and it has 3000 references on Google Scholar. I'm glad it's helped so many people, I'm no expert in PCA or Maths in general, I learned what I needed to write the tutorial and the example code and I think the writing style must have been pretty good as lots of people seem to have been able to follow it.
It means 'which isn't acceptable'. I am also confused as to why they used this turn of phrase, perhaps to sound more colloquial. It sounds weird to me too, and comical, coming from a govt department, but perhaps it is indicating that the privacy commission finds that to be something the population would not approve of, but which it has no actual enforcement mechanism.
Scammers also do this for searches like 'aircanada' (no spaces), including sometimes impersonating the official website while telling you to call a support number as the website is down.
