-
Red Hat unveiled its top secret Ceylon project, which looks like a yet another Java variant to me.

While we have to work with the “old” Java, it worth to know more about how it works. Michael Kopp blogged about the impact of the garbage collector on the performance. It is a good article, which explains the fundamentals of the memory management in Java.
I found an old article about the eXtreme Programming Simplicity Rules. In nutshell:
-
pass all tests
-
expresses every idea that we need to express but nothing more
-
do not duplicate code or configuration
-
have short methods, classes and modules

-
personal motivation
-
personal ability
-
social motivation
