Operation	Time Complexity
Access	O(log n)
Search	O(log n)
Insertion	O(n) for <= 32 elements, O(log n) for > 32 elements [2]

Hosting IPFS from behind NAT/Firewall using a free reverse proxy (ngrok)

1. Expose localhost's port 4001 to public internet using ngrok: ngrok tcp 4001. Tip: Use -region= flag for lower latency.
2. Note the hostname and port returned by ngrok in the form: tcp://hostname:port -> localhost:4001
3. Open the ipfs config json file ~/.ipfs/config
4. Edit as follows: Addresses.Announce=["/dns4/put-the-hostname-here/tcp/put-the-port-here"]
5. Save the config file
6. ipfs daemon

Bitcoin

Es la primera criptomoneda o activo financiero digital descentralizado de la historia que permite realizar transacciones de forma segura, privada y sin intermediarios alrededor del mundo. Satoshi Nakamoto es el pseudónimo que fue utilizado por la persona o el grupo de personas que diseñaron y crearon el ecosistema Bitcoin.

La motivación de Satoshi Nakamoto para concebir Bitcoin fue crear un nuevo sistema de dinero electrónico que utilice por completo una red de pares que no necesite un tercero de confianza (intermediario financiero) para realizar las transacciones y cuya oferta no pueda ser alterada por ninguna otra parte. En otras palabras Bitcoin trasladaría las características deseables del dinero físico (falta de intermediarios, irrevocabilidad de las transacciones) al mundo digital y las combinaría con una política monetaria rigurosa que no se pueda manipular para producir inflación inesperada en beneficio de terceros, acosta de los tenedores de dicha moneda. Nakamoto lo logro utilizando te

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
