What's the deal with a leading underscore in PHP class methods?

What's wrong with overridable method calls in constructors?
...s.levels = levels;
this.isAdjustable = isAdjustable;
}
}
And now you can do any of the following:
new Telescope("X/1999");
new Telescope("X/1999", 13);
new Telescope("X/1999", 13, true);
You can't, however, currently set only the name and isAdjustable, and leaving levels at default....
Convert java.util.Date to String
...14 14:05:09
java.time
The modern way is with the java.time classes that now supplant the troublesome old legacy date-time classes.

Is there an equivalent of 'which' on the Windows command line?
...
@mawg, the original was for where you know the extension since it mirrors which under UNIX (where that extension-adding trickery doesn't occur). I've now added one which can do what you wish but it's no longer a simple command so much as a script. It first tries t...
Differences between fork and exec
...d process (parent) as its parent PID (PPID). Because the two processes are now running exactly the same code, they can tell which is which by the return code of fork - the child gets 0, the parent gets the PID of the child.

What do all of Scala's symbolic operators mean?

These can still be found on ScalaDoc: you just have to know where to look for them. Or, failing that, look at the index (presently broken on 2.9.1, but available on nightly).
Every Scala code has three automatic imports:
// Not necessarily in this order
import _root_.java.lang._...
Ternary operator is twice as slow as an if-else block?
...
RunIfElse(array, 1);
RunConditional(array, 1);
// Now really time it
RunIfElse(array, 1000);
RunConditional(array, 1000);
}
static void RunIfElse(int[] array, int iterations)

I know this has already been answered. But I would like to add my solution as it may helpful for others in the future..
A common key error is: Permission denied (publickey). You can fix this by using keys:add to notify Heroku o...
Non greedy (reluctant) regex matching in sed?
... Holy smokes I can't believe that worked :-) Only thing that sucks is now my script has a Perl dependency :-( On the plus side, virtually every Linux distro has Perl already so probably not an issue :-)
