  • Nobody would be able to understand me because English has diverged so far from 12th century English that it’s a different language. Also I’d be in north America where nobody had even seen a white person. Additionally, I’m 20 ft above the ground right now in a building that didn’t exist back then. Finally, I’d be rightfully blamed for bringing plague to the native tribes of the area and likely killed.

    Assuming those hurdles were all cleared: I’m a mechanical engineer. So, I’d tell the natives where iron ore, coal, and oil was buried and how to extract and refine it. Tell them how to make gunpowder. Speed run making steam engines and lathes. Get north american natives armed, industrialized, and organized against the external European threat.















  • It costs ~$150 to build your own CO2 carbonation setup. After that, refills are pretty infrequent at ~$10. That gets you relatively unlimited sparkling water.

    If you’re jonesing for specific flavors, flavor powders, extracts, and raw sucralose in bulk on Amazon will run you around $20, or ~$100 total for a decent assortment. It’ll pay for itself in like a year and the powders will last you awhile.


  • Depends on how you learn, and what the material is. Stuff that worked for me, in no particular order:

    • Write a cheat sheet for exams, even if you can’t actually use it in the exam
    • Start homework the day the lecture that covers the material is given in class.
    • Try to explain the subject out loud to someone else (real or imaginary). Anywhere you draw a blank when talking is something you need to refresh on. Repeat this until you get it right.
    • For memorization - heavy topics, build an Anki flashcard deck

    All of these techniques are variations on the fact that people learn by repeated exposure. the closer together the initial repetitions are, the higher the retention.



  • Storage data structures. Database tables are designed for fast read/write. Excel is designed for fast simultaneous parallel computation.

    To get a sense of what this looks like, you can read more about their data structures; Databases typically store data in what’s called a “B Tree” and spreadsheets typically store as a format that can be easily converted into a “Directed Acyclic Graph” (although Excel lets you turn off the “acyclic” part if you allow circular references).

    Although, with Excel specifically, there’s probably not much difference since it has some database functionality now.
