Day 1

How to lose at poker (Mike Lee, @bmf)

• emotion/intuition vs. reason in cards - those who ultimately win are not those who follow their intuition and emotions, but those who resist the temptation to do that; e.g. an "inside straight" (5 6 x 8 9) is twice harder to complete than other straights (x 5 6 7 8 x) even though it feels just as likely, so it's reckless to try to get one
• chance of failure is never 0%
• it's not about winning all the time, it's about managing your wins in a sea of losses, and using your losses to your advantage

Notatki z Lambda Lounge meetup

Ogólnie:

• immutability
• higher-order functions
• first-class functions
• stan przekazywany explicit w argumentach, a nie przechowywany gdzieś tam i zmieniany w miejscu przez nie wiadomo kogo
• referential transparency - funkcja dostając dane argumenty zawsze zwróci tą samą wartość
• nie ma rozróżnienia na == vs. equals
