GUIDs don't buy you anything that I can see. Pay attention to JOG and Liebniz equality.

What do you intend to get out of the hobby? I know people who do carpentry as a hobby, and they want to learn about carpentry. I know people who watch birds as a hobby, and they want to learn about ornithology. When I meet someone who does applied mathematics as a hobby, the person probably wants to learn about applied mathematics.

I will let Neo speak to the issue whether he hates me. I didn't really see any evidence of that. Profanity doesn't necessarily equate to hatred.
Neo appears to think very much at a concrete level with little abstraction. He has put tremendous effort into whatever it is he calls his product. xdb or something. Sadly, his apparent inability to abstract things limits his product in spite of his efforts. I am never sure whether to admire his tenacity or to pity his limitations.
While I would like nothing better than for Neo to come up with something truly revolutionary for all his efforts, I try not to encourage him because I think the possibility exceedingly unlikely.
