Sleep IoT Quest - Day 3 Progress Update

Aug 18, 2025

Today was a bit special, much bigger chapter - no real practice code, less time to spend.
No problem, just ask ChatGPT to create a code example that illustrates all concepts from this chapter and try to get as far as you can in the given time :)
Today might have sucked a bit, but nothing lasts forever and we can still wrestle a win from this challenge today.

Completed

  • Rust Book Ch. 3: active read (marked + commented) -> ~25/40p
  • Guessing Game: recreated from memory with variation
  • Sidequest: Find a new apartment in bulgaria

Process

  1. Paste chapter into AI and ask for a code example that incorparates and illustrates all concepts from this chapter and step by step implementation guide.
  2. Read the code, notice the parts you don't understand
  3. Now read the chapter slowly with a marker and close the gaps in your knowledge
  4. Delete the code from the file and recreate it from memory, allowing 5–10 min struggle before any lookup.

Lookups needed

None, still reading that chapter and marking it up :)

Gotchas noticed

  • a ";" changes expressions into statements -> no eval, no return value

Total Time Spent

  • 1.5h of active reading (marking up the relevant parts in the pdf

PCT (Project Cumulative Time): 4h57m
