Add a security.txt to Your Web Applications

Your web application is under the constant thread of hackers. It does not matter if you have a small pet project application on the internet or a big commercial site. As soon as it is accessible from the internet, someone will attack it.

Shorten Your Feedback Cycle

One of the most important ideas of agile software development is for me the short feedback cycle.

And your applications will run much faster if they only fetch the data you really need.
