Best practices for using Markers in SLF4J/Logback
..., such as sending an email to an administrator for some seriously critical errors. Not all errors always fall in the same category; some have to be dealt in an appropriate way.
Or, when a user quits from your service, it usually goes to an INFO log, but you can also use a marker for such instances,...
What is the advantage to using bloom filters?
... additional linear
space overhead for pointers. A Bloom
filter with 1% error and an optimal
value of k, on the other hand,
requires only about 9.6 bits per
element — regardless of the size of
the elements. This advantage comes
partly from its compactness, inherited
from arrays, and...
Why is try {…} finally {…} good; try {…} catch{} bad?
...ce is that try...catch will swallow the exception, hiding the fact that an error occurred. try..finally will run your cleanup code and then the exception will keep going, to be handled by something that knows what to do with it.

Calling parent class __init__ with multiple inheritance, what's the right way?
... gives you more consistancy and make eventual refactorings easier and less error-prone. An example of how to do that:
class C(A, B):
def __init__(self):
print("entering c")
for base_class in C.__bases__: # (A, B)
base_class.__init__(self)
print("leaving c"...
Malloc vs new — different padding
...memory it occupies. So it's hard to see how the difference could result in errors transferring data.
Is there any sign what the author of that comment thinks about objects on the stack or in globals, whether in his opinion they're "padded like malloc" or "padded like new"? That might give clues to ...
