Possible heap pollution via varargs parameter
...hrow a CCE
B b = listOfBs.get(0);
@SafeVarargs does not prevent this at all. However, there are methods which provably will not pollute the heap, the compiler just can't prove it. Previously, callers of such APIs would get annoying warnings that were completely pointless but had to be suppressed ...

What makes Lisp macros so special?
...bleByTwo = [x for x in range(10) if x % 2 == 0]
yields a list containing all even numbers between 0 and 9. Back in the Python 1.5 days there was no such syntax; you'd use something more like this:
divisibleByTwo = []
for x in range( 10 ):
if x % 2 == 0:
divisibleByTwo.append( x )

How do streaming resources fit within the RESTful paradigm?
... RESTful service you can create, read, update, and delete resources. This all works well when you're dealing with something like a database assets - but how does this translate to streaming data? (Or does it?) For instance, in the case of video, it seems silly to treat each frame as resource that ...
Differences between “java -cp” and “java -jar”?
...the first version to start a java application just because it has less pitfalls ("welcome to classpath hell"). The second one requires an executable jar file and the classpath for that application has to be defined inside the jar's manifest (all other classpath declaration will be silently ignored.....
