Building vs. Compiling (Java)
...s.
Compiling test sources.
Executing tests (unit tests, integration tests, etc).
Packaging (into jar, war, ejb-jar, ear).

Generating reports.
So as you can see, compiling is only a (small) part of the buil...
What does “connection reset by peer” mean?
...cognize the connection; it will send back a packet with the RST bit set in order to forcibly close the connection.
This can happen if the other side crashes and then comes back up or if it calls close() on the socket while there is data from you in transit, and is an indication to you that some o...

What is “callback hell” and how and why does RX solve it?
...e from event handling code. You can easily handle details like async event ordering that are a nightmare when using state variables.
