The more time we have to do the job (especially in the office), the longer it takes. Work complicates to fill the available time. Check out Parkinson’s Law and understand why!

Everything around us makes us concentrate on what is available immediately and instantly. Short-term gains and results are much more appreciated than long-term with much better results. Long-term thinking and acting following this thought is the key to a peaceful life on your own terms.

A simple example of how to introduce a Universally unique identifier (UUID) into your project. You just need to remember a small modification in the migration and the column type change.

Have you wondered about the nature of technology? Technology is neither good nor bad, nor is it neutral. The invention is the mother of necessity. The same technology may have completely different results. New needs, as well as new technical possibilities, make the impossible possible.

Positional bindings can be problematic due to the order when building large queries with many different functions. Named bindings can be of great help in our challenges. It is not necessary to know the position to be able to refer to the variable. Creating reusable and maintainable queries doesn’t have to be complicated.

Don’t be afraid to make mistakes. Even the best programmers make mistakes. However, minimize their impact and react quickly to the most critical problems. It is much better to make mistakes but fix them quickly than to delay the development phase and not provide functionality.

Try to use setup_all to prepare the data once and re-use it in tests. Use tags to have a better context and be able to exclude some tests. Prepare a processing pipeline to check the quick tests first, and when they do not fail, take care of the more time-demanding tests.

The macro Ecto Query dynamic/2 allows you to build query fragments and interpolate them into one large query. We get easy-to-manage query building in an accessible way. It allows you to control the parameters from the user and transparently create filtering of data stored in the database.

Code review can be an opportunity to sharing knowledge. Finding errors is a side effect of the entire code review process. Thanks to code review, you can promote one standard style of changes to the entire team. Don’t be afraid to ask if you don’t understand something.
