View how-to-copy-aws-rds-to-local.md
  1. Change your database RDS instance security group to allow your machine to access it.
    • Add your ip to the security group to acces the instance via Postgres.
  2. Make a copy of the database using pg_dump
    • $ pg_dump -h <public dns> -U <my username> -f <name of dump file .sql> <name of my database>
    • you will be asked for postgressql password.
    • a dump file(.sql) will be created
  3. Restore that dump file to your local database.
    • but you might need to drop the database and create it first
    • $ psql -U <postgresql username> -d <database name> -f <dump file that you want to restore>
  • the database is restored

View action-creator-vs-reducer.md

When should you use action creator and when reducer?

Action creator

  • you need to have side effects
  • you need to read from store to decide what to do
  • you need to dispatch more than one action
  • action produced by action creator needs to contain all the data reducer can need to shape the components state

Reducer

  • should not have any side effects

Google's authentication-less on-the-fly image resizing service

I found it while poking around the Google+ HTML. Jotting down some notes felt like a good idea, so here goes. If you know more about this API, let me know, please!

(Word of warning: I spent ~30 minutes on both my experimentation and this here write-up, so it might not be the most thought-provoking, brilliant thing you read today.)

This is my response to an email asking about Domain-Driven Design in golang project.

Thank you for getting in touch. Below you will find my thoughts on how golang works with DDD, changing it. This is merely a perception of how things worked out for us in a single project.

That project has a relatively well-known domain. My colleagues on this project are very knowledgeable, thoughtful and invested in quality design. The story spelled out below is a result of countless hours spent discussing and refining the approach.

Conclusions could be very different, if there was a different project, team or a story-teller.
