Well, Hi there, it me. Back then I was 17 and wading through software rendering so (light) mesh tessellation, triangle projection (twice, for a stereoscopic anaglyph renderer), triangle filling, texture mapping, with at most 300 objects, all in crappy crashy C (first with VESA, then SDL eased my life...) with lots of misunderstandings about pointers.

I was welllll over my head with complex stuff, and sorting didn't appear in the profiles, so... I guess you can call that profile-guided learning? I had the formal training, later on, and even then it didn't stick until I faced the actual complexity problem head-on.

I'll never forget that whole weekend with my AMD Athlon 900 at 100% CPU sorting a 200 000 words dictionary... It was still not finished on Monday. Implemented (a very primitive) insertion sort and it was done in less than 2 minutes...

That was my 10000-a-day day https://xkcd.com/1053
