How to get the class of the clicked element?
...on() {
var myClass = $(this).attr("class");
alert(myClass);
});
Equally, you don't have to wrap the object in jQuery:
$("li").click(function() {

alert(myClass);
});
And in newer browsers you can get the full list of class names:
$("li").click(function(...
Is JSON Hijacking still an issue in modern browsers?
...addEventListener('click', toggleCapture);
toggleCapture();
[].forEach.call(document.body.querySelectorAll('input[type="button"]'), function(el) {

Access to Modified Closure
...
In this case, it's okay, since you are actually executing the delegate within the loop.
If you were saving the delegate and using it later, however, you'd find that all of the delegates would throw exceptions when trying to access files[i] - they're capturing the var...

In Postgresql, force unique on combination of two columns
...I like the suggestion of a primary key over unique here, because we do not allow NULL values in this case. From the PostgeSQL docs: "Note that a unique constraint does not, by itself, provide a unique identifier because it does not exclude null values.)" postgresql.org/docs/8.1/static/ddl-constraint...
Is “argv[0] = name-of-executable” an accepted standard or just a common convention?
...
Guesswork (even educated guesswork) is fun but you really need to go to the standards documents to be sure. For example, ISO C11 states (my emphasis):
If the value of argc is greater than zero, the string pointed to by argv[0] represents the program name; argv[0][0] shall b...
Performance - Date.now() vs Date.getTime()
...
These things are the same (edit semantically; performance is a little better with .now()):
var t1 = Date.now();
var t2 = new Date().getTime();
However, the time value from any already-created Date instance is frozen at the time of its construction (or at whateve...
