What's the shebang/hashbang (#!) in Facebook and new Twitter URLs for?
...e.com/webmasters/ajax-crawling/
This technique has mostly been supplanted by the ability to use the JavaScript History API that was introduced alongside HTML5. For a URL like www.example.com/ajax.html#!key=value, Google will check the URL www.example.com/ajax.html?_escaped_fragment_=key=value to fe...

Why am I merging “remote-tracking branch 'origin/develop' into develop”?
...ure branch would be duplicated on master as part of the linearization done by git rebase. This would make the development history harder to review, not easier.
Beware: git rebase might not do what you expect it to do, so review the results before pushing. For example:

initialize a numpy array
...alizing entries.
However, the mentality in which we construct an array by appending elements to a list is not much used in numpy, because it's less efficient (numpy datatypes are much closer to the underlying C arrays). Instead, you should preallocate the array to the size that you need it to be...

Why should I use the keyword “final” on a method parameter in Java?
...gn a parameter/argument variable to an object other than the object passed by the calling method. In the examples above, one should never write the line arg =.

...in a file (properties/xml file) is the next step.
Metadata driven (as done by an ORM like Hibernate/JPA) is the last step.
Hardcoded has the disadvantage that your code is likely to become DB-specific and that you need to rewrite/rebuild/redistribute on every change. Advantage is that you have it i...
