Java EE 6 @javax.annotation.ManagedBean vs. @javax.inject.Named vs. @javax.faces.ManagedBean
...ontainer, which is a servlet container.
So when you see the Managed Bean word, you should ask about the context or type of it.(JSF, CDI, EJB, etc.)
Then you might ask why we have many of these containers: AFAIK, Java EE guys wanted to have a dependency injection framework, but they could not gath...
Checkout another branch when there are uncommitted changes on the current branch
...it means for a file to be in a branch, which in turn requires defining the word branch properly. (See also What exactly do we mean by "branch"?) Here, what I really mean is the commit to which the branch-name resolves: a file whose path is P is in branch1 if git rev-parse branch1:P produces a hash...
What is the Java string pool and how is “s” different from new String(“s”)? [duplicate]
... simply wrong, so the upvotes should be removed. The construct new String("word") would only create a new string in the pool if there was no string literal in the pool with the same value. It will however create a new String object that references any existing literal in the pool, hence the result o...
How to get HTTP Response Code using Selenium WebDriver
...
In a word, no. It's not possible using the Selenium WebDriver API. This has been discussed ad nauseam in the issue tracker for the project, and the feature will not be added to the API.

Bomb dropping algorithm
...reduce the effort of later bombing away layer 2 by more than
X? In other words, we have to prove we can be greedy in reducing the outer
perimeter.
But, we do know we can be greedy. Because no bomb in layer 2 can ever be more
efficient in reducing layer 2 to 0 than a strategically placed bomb i...
jQuery Mobile: document ready vs. page events
... pageload event could therefore be used to access the loaded page.
In few words this is happening because you are sending additional parameters through pageChange.
Example:
<a data-role="button" data-icon="arrow-r" data-iconpos="right" href="#care-plan-view?id=9e273f31-2672-47fd-9baa-6c35f093a...
Do you (really) write exception safe code? [closed]
...Exceptions are for exceptional processing failure, not for code bugs.
Last words
Now, the question is "Is this worth it ?".
Of course, it is. Having a "nothrow/no-fail" function knowing that the function won't fail is a great boon. The same can be said for a "strong" function, which enables you to w...
When and why are database joins expensive?
...uation.
The reason that I responded so savagely was that the statement as worded says that
Joins are cartesian products...
This may not be what was meant but it is what was written, and it's categorically untrue. A cartesian product is a relation. A join is a function. More specifically, a j...
Context switches much slower in new linux kernels
...s BIOS configuration for the C-states and dances to its own tune. In other words, even if you completely disable all C states in your PC's (or server's) BIOS, this driver will still force them on during periods of brief inactivity, which are almost always happening unless an all core consuming synth...
Accessing class variables from a list comprehension in the class definition
...s, as well as generator expressions do not mix.
The why; or, the official word on this
In Python 3, list comprehensions were given a proper scope (local namespace) of their own, to prevent their local variables bleeding over into the surrounding scope (see Python list comprehension rebind names ev...
