    Your willpower is

    Judges would make more favorable
    decisions after those breaks. After a lunch
    break the rates of favorable decisions
    immediately jumps to 65% again.
    Dotted lines represent food breaks
    In the morning we started with
    65% of favorable decisions and at
    the end of the day this rate
    steadily drops to zero.
    As time goes by, less favorable decisions occur

     Webpack ❤
     Module bundlers
     are here to stay
     They're here, but not quite there
     yet. HTTP/2 push is hard and
     native modules aren't fast enough.
     NATIVE MODULES
     Tree-shaking, cache invalidation
     and other code transformations
     (eliminating dead-code, uglifying
     code, and pre-evaluation)
     OPTIMISATIONS
     Browsers adopting the same
     runtimes is dangerous, as it leads
     to an ecosystem where a single
     actor has too much power.
     LANGUAGE FEATURES
     JSX is here to stay, and even if
     we're not using React, TypeScript
     is also not going anywhere soon.

     an audience with Master Foo to learn
     more about the Way.

     them how many years of experience
     they have in a new programming
