The learning curve become longer and steeper.As the increasingly complex, the newbie or newcomers become harder.To make the source code sensible interface, consistent layout, elegant code."Do one thing, and does it well", "simple, and reliable"To evaluate, to comment the source by fairTry to interact with the kernel instead of reading itStay fresh, stay abreast, stay positiveI proceed with trepidation when converting my experience in
