"I will never ever make any statement about performance that is not based on measurement and I will never ever advise anybody on how to write their code without saying write it and measure. I just will not speculate. I think people who do speculate about this should not speculate about it and they should write it, run it and measure it."
Joseph Leslie Armstrong was a computer scientist working in the area of fault-tolerant distributed systems. He is one of the co-designers of the Erlang programming language.
"Lets unbreak the web. The web is broken. Lets go out and un-break it and lets bring computation back to these supercomputers that weve got in our pockets [...] Lets ensure that our personal data is owned by us and not by large corporations [...] Lets make computing easy again like it was in the past. Lets build apps that could communicate with each other."
"API in programming languages is totally stupid because they do not capture order."
"I do not think we can build systems that are large with large components."
"We are computer scientists, we are slaves who works for these big companies [Google, Facebook]."
"So whats wrong with the shell? and whats wrong with Erlang? Its not LISP!"
"The spec does not tell me what to do. What do I program? [...] I thought this is crazy, we are building products with specifications and things, and the specifications doesnt say whats supposed to happen. Then when you get to this point in the code where you dont know whats going to happen, everybody knows how programs it. I thought thats crazy because I didnt know and I thought everybody could interpret that differently and they could make an ad-hoc decision. So I thought to myself, the only sensible thing to do is crash. We just crash this call because we dont know what to do."
