01ARTICLES & TUTORIALS

MAKE INVALID STATES UNREPRESENTABLE

Invalid states can lead to runtime errors and less reliable code. However, by shrinking the gap between representable, valid states, errors can be moved from runtime to compile time, which allows them to get caught much earlier. Type systems can and should be used to model business logic that makes invalid states impossible and unrepresentable. This article goes through a few examples, such as a “Color” type that prevents invalid colors.

WHY DON'T WE TALK ABOUT MINIFYING CSS ANYMORE?

Minifying CSS files directly is less important today compared to before because popular front-end frameworks automatically handle minification and code-splitting for developers. Modern compression algorithms can reduce file sizes a lot and HTTP/2 can efficiently deliver multiple smaller CSS files. As a result, developers no longer have to manually minify their CSS.

WHY AREN'T WE TALKING ABOUT CONTINUOUS IMPROVEMENT?

Continuous improvement is a key principle of Agile and Lean, but it's not as popular anymore in tech companies. Layoffs and transformations often happen without employee involvement, and there's a general lack of engagement in improving processes.
