I'm a developer for almost three years, i (like) to think that i'm good, i have deep knowledge of my stack and i can design and implement almost any feature that the seniors at my team can implement, but i have i problem with the final quality of my code. My code is clean and follow the guide-lines, but i feel that i make to much mistakes, there is always a corner case that i don't think about or some test that is trivial to the QA team but i didn't do, and my code end up being broke. This 'behavior' also happen with maths, i know the theorems and the content that i need to know to solve questions but i always miss calculate something and end up with the wrong result, one clear example of this was my last "calculus 2" exam, all the steps were right, but all the results were wrong; TL, DR: I know my stack and the tools but i make silly mistakes that end up breaking my code; how can one get better at this? from Hacker News: Front Page http://ift.tt/2...
