In the past weeks I have worked on something different than usual, a python project. This project was started a couple a years ago with Flask and I need to make some improvements.

Back in the days I used to work with Django, so it wasn’t difficult getting familiar with Flask. The major problem was to get python-saml work on Amazon Elastic Benstalk correctly and after a lot of googling I managed to get all the pieces work togheter, but I couldn’t find a solution with all the information in one place, so I decided to write this post.

These days I am working on a frightening task, a major update of a Rails project (3.2 to 4.2).

I wanted to write a post with the little tricks I am adopting to keep this task as simple as possible; but I found a very good article that explains most of them: How to make your next Rails upgrade easier

The only addition I can make to this post is the suggestion to use Docker, with docker-compose, to have a completely new environment where you can fearlessly play around with changes and updates.

Last but not least, in my case the target project doesn’t have a real test suite that can be reliable. So now, before doing the real upgrade, I am adding some functional tests that cover the main parts of the site. This way I can be more confident that all works well.

I hope you found the article helpful as I did.

See you soon!

Today I scratch the surface of a “little” useful command: find

First of all, some context. I have a WordPress site that manages all media with the awesome plugin WP Offload S3, but for some reason I need to disable this plugin and return back to the default WordPress media management.
