In sixth grade, during the physics lesson, I learned that two objects cannot exist in the same space. Obvious, right? Well, Mr. Bunău (the physics teacher) just made obvious something that everybody instinctively knows. I certainly knew this, but didn’t put it into words and it was amazing for me at the time what a simple concept, how obvious, yet I didn’t think to formulate it in to words. This is why words mean things, putting concepts into words helps other people better understand your thoughts.

I hate it. As programmers we are used to short feedback loops: write code compile (this step can be very short to non-existent for some technologies, see Vite HMR or Precompiled headers or Mold, a fast linker) optionally (if it compiles): play around with the app get feedback Arguably, the write code part is the longest in this chain/circle since it requires the most thought and preparation. The others, depending on the size of the project, are on the magnitude of seconds.

Less tricks for more productivity on the command line. Pun intended.
