Practice Makes Perfect

After our morning standup, I drove over to Micah’s house to pick up my work laptop! Micah and I were able to talk about what the expectations were for the kata performance. This has given me a good idea of what I should be practicing on throughout this week. I’ll definitely be putting in the practice, so that the kata performance falls within the 5-10 minute range and that the theme of TDD will be displayed clearly.

Today’s Tasks

• Bowling Game Kata
• Euler #3
• Set up macbook!

Challenges

Euler

• Figuring out the correct alogrithm with a low enough runtime so that when n becomes large the program is able to run successfully.
  • Figuring out how to use recursion to factorize the number.
  • What data structure to hold all the factors?
    • Sets, Lists, Sequences, etc.

Kata

• Figuring out the IntelliJ shortcuts to use for the kata performance
• Getting into the habit of performing the kata as TDD being the focal point.

TIL

• Difference between mod and rem in their under the hood implementation. On the surface they both have the same functionality but…
  • mod:
    • means Gaussian mod, so the result will always be non-negative.
    • returns the difference of the first number and the biggest integer multiple of the second number that is less than the first number
  • Whereas, rem:
    • implements ANSI C’s % operator
    • is just the remainder

      user=> (mod -10 3)
      ;; 2
      ;; The greatest integer multiple of 3 that is less than -10 is -12
      ;; -10 minus -12 is 2
      user=> (rem -10 3)
      ;; -1
      

Looking Ahead

I have been pretty consistent in waking up around 4:00 - 4:15 and getting to the office around 5:15. It has been nice getting some work done and being productive before the standup. Although I have been getting up early, I need to do a better job in getting enough sleep and staying focused on getting through my daily tasks.
