What I Didn't Know about Functional Programming until 2020

What I Didn't Know about Functional Programming until 2020

  1. Programming using a series of transformations and aggregations, something I've been doing for years, is known as programming in the map/reduce style.
  2. The more abstract the type is, the greater its cardinality, and the smaller the set of operations it supports. So make use of universal quantifiers, particularly by implementing fully parametric functions. They guide you on how to implement their term-level definitions by narrowing down the number of possible implementations. In other words, the type system of Scala (or Haskell, for that matter) is not only great for capturing compile-time errors, but is also capable of leading you to the correct solution.
  3. You can encode union types by combining different Scala features such as type constructors, subtyping and implicits, and by taking advantage of the Curry-Howard Isomorphism and De Morgan's Laws for neg

How to stop adverts appearing on your Samsung TV

I'm getting adverts in my TV's UI, help!

Samsung's otherwise excellent 2016 range of UHD TVs received an update that added advertisements to the UI. This has been complained about at great length on Samsung's forums and repeatedly, Samsung have refused to add an option to remove them.

The ads interrupt the clean UI of the TV and are invasive. Here's an example of how they look:

This guide was originally posted on Samsung's TV forums but unfortunately, that site is a super-slow and barely accessible unusable mess.
