For job-hoppers and contractors. If you arrive at a company, what is the first thing you push for? For instance, I usually implement a good feature-branch flow with branch pipelines and a strict merge-to-develop etiquette with mandatory merge requests. It makes my work easier and once the team is used to it, they also really like it. No more messy development branches. I also request a small office stool next to my desk to make code reviews, three amigos and pair programming easier. It is a small thing but I noticed that people are more eager to discuss things if they have a place to sit. | 
These are from my notes (the quotes below may be boring but related discussions are good imo):
"My working theory is something like “romanticism/emotionalism vs. abstract rationalism”; if you’re writing something that benefits from immediate experience and emotional input (e.g. Kafka writing about nightmarish bureaucracy after working all day in an insurance firm) then it is better to write at night, after the events of the day have happened and your mind has been operating for 12+ hours." https://news.ycombinator.com/item?id=18369337
"Classes get in the way between the programmer and the problem. They force you to reify your thinking into "things" (classes) that demand names and citizenship rights, so to speak, in the system. These "things" don't really exist, but we act like they do, and so increasingly see the problem in terms of the classes we've defined." https://news.ycombinator.com/item?id=3717715
"One thing that I find sorely missing in many teams is onboarding documentation. So when you come in, document everything that you need to do (required permissions, development environment setup, mailinglists, subscriptions) and how to do it." https://news.ycombinator.com/item?id=17353854
"The real value of Flask is that it makes you appreciate what Django does by default. When I first started learning Python / web frameworks, I went with Flask because it was smaller and "simpler". As my project grew however, I had to organize it. I was basically imitating what Django gives you by default, though less cleanly." https://news.ycombinator.com/item?id=16935441
