2. "Name a couple common errors that would occur when converting a program from Python 2 to Python 3."

I'd say #ChatGPT3 #GPT3 aced this. Esp. putting the "print" change front and centre. No real complaints.

3. "Give an example of when one would use inheritance in #Postgres #PostgreSQL, and why."

#ChatGPT3 #GPT3 aced it again - very thorough. I'll note that I ran this question twice in two different sessions, and it gave different examples, but both very good.

4. "How does #ATPSynthase work? What would be a macroscopic analogy of it that one may encounter in our macroscopic world?"

Good response, and good choice of analogy. No complaints for #ChatGPT3 #GPT3.

5. "Why would one avoid using a linear #ActivationFunction in a #NeuralNetwork?" #AI

No, #ChatGPT3 #GPT3. The derivative of a linear activation function is *always* positive; it has no vanishing gradient. The problem it has is that you can't backpropagate (constant derivative) and can mathematically reduce a network with linear functions down to a single layer.

6. "Name an Icelandic band whose members include, among others, Kata (Katrína), Arnar, Ása (Vilborg), and Alexandra." .. "Name an Icelandic band named after a prehistoric mammal."

No, #ChatGPT3 #GPT3, for God's sake, it's #mammut (#Mammoth). #Mammút! Those are not the members of Vök. You just assigned them roles, too - Arnar doesn't sing, Alexandra isn't a drummer, etc. And Hekla isn't named after a wild sheep, nor are sheep breeds #prehistoric. Epic fail.

7. "What would be the possible impact of using waste geothermal water for root heating of plants in the #Reykjavík area? Explain what you would expect the growth, survival rate and yield for the following plants to be like: A) #tomato; B) #kale; C) #eggplant; D) #monstera"

This was unfair to #ChatGPT3 #GPT3, as I'm a researcher on this and know the answers, while it's forced to speculate.

* Tomatoes: excellent growth, still difficult fruit set

* Kale: ~3x more yield
...

* #Eggplant: may not die (probably will), but won't grow, and will just slowly waste away

* #Monstera: will still die.

#ChatGPT3 #GPT3's speculation was reasonable for the most part, though misguided about whether Monstera's main concern would be water composition rather than, you know, mean #July high temperatures being 14°C. Still, not too bad, and right about needing more research.

8. "What #mineral, produced by #subglacial #eruptions and spread via #aeolian distribution, is a problem for farmers in #Iceland, and why?"

#ChatGPT3 #GPT3 failed this (admittedly difficult) question (the answer is allophane, which binds phosphorus and other minerals, water, and reduces soil cohesion).

9. "Name one or more common #zeolites that one may find in southwestern #Iceland."

While #stilbite would have been at the top of my list, all of those can definitely be found in southwestern Iceland. Score one for #ChatGPT3 #GPT3.

10. "Apart from #mangosteen, name three #Garcinia species that are popularly consumed where they're cultivated."

Well... #ChatGPT3 #GPT3 sort of erred here, in that the first #fruit it named is just an obsolete scientific name of the second fruit, under which a lot of Garcinia-based fad weight loss products are marketed). I asked it for another, and... well, that's a pretty obscure one, I was expecting something like #achachairu, but whatever, it works.
