"All languages will have side effects. They will have some form of mutability. The whole goal is to try to decrease this mutability as much as possible."
"When you are writing a massively complex highly distributed system, you need more just than a language, Erlang is just a programming language. You need architectural patterns, you need to start thinking in term of how you distribute your system."
"By learning them, and understanding their paradigms, and by programming in a functional way, you will end up being much more productive and youre becoming much better programmers."
"A system which is strongly available means that it is not reliable because of the reliability you might need to take down the machines. On the other hands if you dont worry about the reliability of your data, as long as youve got a value which is not too old, you can go in and distribute it, and scale that way."
"What is the point with OTP? First of all, you get much more less code […] Less bugs […] Much more solid and tested code. Much more deep learning curves […] Performances will be slightly impacted due to the layers."
"What the Sunway TaihuLight, Raspberry Pi and Parallela board have in common? It is the heterogeneous multi-cores. So you have different types of cores, and thats the future of the computers we will working on today. The shift in multi-cores is inevitable."
"What you need to do is to make sure your threads become immutable. So you can change a data within a thread, but if you got two threads communicating with each other, you need to mimic this whole message passing approach. You need to copy the data from one threads to another, avoiding having shared state."
