Is there a way to @Autowire a bean that requires constructor arguments?
...
Well, from time to time I run into the same question. As far as I know, one cannot do that when one wants to add dynamic parameters to the constructor. However, the factory pattern may help.
public interface MyBean {
// here be my fancy stuff
}

What is a “callback” in C and how are they implemented?
...k:
typedef void (*event_cb_t)(const struct event *evt, void *userdata);
Now, define a function that is used to register a callback:
int event_cb_register(event_cb_t cb, void *userdata);
This is what code would look like that registers a callback:
static void my_event_cb(const struct event *ev...

When to use virtual destructors?
...Here, you'll notice that I didn't declare Base's destructor to be virtual. Now, let's have a look at the following snippet:
Base *b = new Derived();
// use b
delete b; // Here's the problem!
Since Base's destructor is not virtual and b is a Base* pointing to a Derived object, delete b has undefin...
Why in Java 8 split sometimes removes empty strings at start of result array?
...n't match zero-length string, you don't need to do anything.
If you don't know whether the regex can match zero-length string or not, do both the actions in step 1.

@MichaelMikowski now you've just hidden your infinite loop, but your code will run slow. I'd argue that it's better to have code break in a bad way so you catch it in development. Putting some bs maximum iterations break in is sloppy. Hidin...
