DNI Electrónico en Mac

El lector que voy a usar es el SVEON SCT011M, que es el mas barato que encontré en tienda física y tiene un precio razonable en Amazon: https://www.amazon.es/dp/B072LTLZW3/

Estos son los pasos que he seguido:

Descargar Firefox (he probado con la ultima version, 86.0.1)
Enchufar el lector, sin el DNI (no se si es importante hacerlo aquí o se puede hacer luego, pero mejor no nos arriesgamos, yo lo hice aquí y me ha funcionado)
Descargar https://www.dnielectronico.es/descargas/software_MACOS/libpkcs11-dnie-1.6.7_x64.pkg para Intel, o https://www.dnielectronico.es/descargas/software_MACOS/libpkcs11-dnie-1.6.7_arm64.pkg para ARM (estos enlaces estan en la web oficial del DNI Electrónico, https://www.dnielectronico.es/PortalDNIe/PRF1_Cons02.action?pag=REF_1113)
Instalar el paquete (los ficheros se copiaran en /Library/Libpkcs11-dnie, y en esa misma carpeta se instalara una app para desinstalarlo en el futuro cuando algo vaya inevitablemente mal).

React "Hello World" Examples

Below are a small collection of React examples to get anyone started using React. They progress from simpler to more complex/full featured.

They will hopefully get you over the initial learning curve of the hard parts of React (JSX, props vs. state, lifecycle events, etc).

Usage

You will want to create an index.html file and copy/paste the contents of 1-base.html and then create a scripts.js file and copy/paste the contents of one of the examples into it.

Problem-Solving Games

My daughter and I love playing problem-solving games together. After completing a few I asked for recommendations on Twitter. Here's the list.
