One of the most salient features of our Tech Hiring culture is that there is so much bullshit. Everyone knows this. Each of us contributes his share. But we tend to take the situation for granted.

Here are some relevant links from the talk:

• Tony Hoare - Wikipedia
• Israel Ferrer Camacho - the Burrito design pattern
• android/camera-samples Camera2Burrito
• Google Authenticator super Burrito activity
• Beethoven - Symphony No.9 (10000 Japanese) - Freude schöner Götterfunken - YouTube
• reddit#androiddev Which areas of Android development are bad and need to change?
• The infamous video: The price of ENUMs #PERFMATTERS https://www.youtube.com/watch?v=Hzs6OBcvNQE
• Here is an insightful, sad and honest answer from Dianne Hackborn (Android team) to the answer: "How should I design my Android application? What kind of MVC pattern should I use? What should I use for an event bus?"

"We often see questions from developers that are asking from the Android platform engineers about the kinds of design patterns and architectures they use in their apps. But the answer, maybe surprisingly, is we often don't have a strong opinion or really an opinion at all."

Here is the quote of Tony Hoare showing what the right way to own your mistakes

I call it my billion-dollar mistake. It was the invention of the null reference in 1965. At that time, I was designing the first comprehensive type system for references in an object oriented language (ALGOL W). My goal was to ensure that all use of references should be absolutely safe, with checking performed automatically by the compiler. But I couldn't resist the temptation to put in a null reference, simply because it was so easy to implement. This has led to innumerable errors, vulnerabilities, and system crashes, which have probably caused a billion dollars of pain and damage in the last forty years.
