Instrucciones para instalar el DNI Electrónico en un Mac en 2021

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:

  1. Descargar Firefox (he probado con la ultima version, 86.0.1)
  2. 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)
  3. Descargar libpkcs11 para Intel o para Apple Silicon. Estos enlaces estan en la web oficial del DNI Electrónico por si quieres ver si hay alguna versión más reciente.
  4. Instalar el paquete (los ficheros se copiaran en /Library/Libpkcs11-dnie, y en esa misma carpeta se instalara una app para desinstalarlo en e

Faster Rails tests

Feedback loop speed in one of the biggest contributing factors to overall development time. The faster you get results, the faster you can move on to other things. A fast enough test suite is therefore critical to teams' success, and is worth investing some time at the beginning to save in the long run.

Below is a list of techniques for speeding up a Rails test suite. It is not comprehensive, but should definitely provide some quick wins. This list of techniques assumes you're using minitest, but most everything should translate over to rspec by simply replacing test/test_helper.rb with spec/spec_helper.rb.

How to connect a Heroku application to an Amazon RDS PostgreSQL instance, forcing SSL and certificate chain verification

1 - Download the RDS certificates (root plus region-specific intermediate ones) bundle:

wget -O config/rds-combined-ca-bundle.pem https://s3.amazonaws.com/rds-downloads/rds-combined-ca-bundle.pem

2 - Add config/rds-combined-ca-bundle.pem to the repository and redeploy to Heroku.

3 - Update the DATABASE_URL env var:

My choice: Dave Bass’s rand().to_s() trick

Dave Bass proposed this which I picked up for my implementation (here for an 8-chars token):
