String, StringBuffer, and StringBuilder
...n a single thread then it is better to use StringBuilder. StringBuilder is more efficient than StringBuffer.
Situations:
If your string is not going to change use a String class because a String object is immutable.
If your string can change (example: lots of logic and operations in the construct...
Travel/Hotel API's? [closed]
...y/booking requests with several response options, including JSON, which is more convenient and lightweight than the (unfortunately) more widespread XML.
As you immediately access their API, you can start developing and testing, but still need their approval to launch the site, basically to make su...
comparing sbt and Gradle [closed]
...
There are two more differences I'd add: * In SBT, it's easier to self-manage dependencies, IMO. * The SBT test runner seems faster; I suspect there's some cunning concurrency involved here but I'm guessing. SBT seems like a more capable b...
DTO = ViewModel?
...del of the view. ViewModels typically are full or partial data from one or more objects (or DTOs) plus any additional members specific to the view's behavior (methods that can be executed by the view, properties to indicate how toggle view elements etc...). You can look at the viewmodel as all the d...
When should you use 'friend' in C++?
...ange the name.
You can take this simple example further by considering a more complex class such as a Window. Quite likely a Window will have many function/data elements that should not be publicly accessible, but ARE needed by a related class such as a WindowManager.

session.cookie_httponly or the httponly attribute to session_set_cookie_params() (Protec...
“Eliminate render-blocking CSS in above-the-fold content”

Imho Google is starting a new "hype" (when I have a look at all the question about it here on Stackoverflow) ...!

Should I use #define, enum or const?
...isdeleted:1, ismodified:1, isexisting:1;
};
Don't ever use that. You are more concerned with speed than with economizing 4 ints. Using bit fields is actually slower than access to any other type.
However, bit members in structs have practical drawbacks. First, the ordering of bits in memory varie...
The difference between fork(), vfork(), exec() and clone()
...
vfork avoids the need for temporarily comitting much more memory just so one can execute exec, and it is still more efficient than fork, even if not nearly by as high a degree. Thus, one can avoid having to overcommit memory just so a hunking big program can spawn a child proce...
