Reinvent the Wheel

I really enjoyed this post by Matthias Endler titled Reinvent the Wheel.

As you might guess, the post takes issue with the age-old engineering dogma not to reinvent the wheel. Matthias points out that even the wheel itself has been invented multiple times throughout history—there is real value in revisiting existing solutions with fresh eyes.

He also notes that even if it might seem foolish or redundant to try to improve on an established tool, implementing something yourself is often the single best exercise for truly understanding how it works under the hood.
