What is “callback hell” and how and why does RX solve it?
...e from event handling code. You can easily handle details like async event ordering that are a nightmare when using state variables. I found RX was the cleanest implementation to perform a new network request after 3 network responses returned or to error handle the whole chain if one does not retur...
Where can I find the “clamp” function in .NET?
...er that with double and float, the CompareTo method corresponds to a total order where NaN is less than all other values, including NegativeInfinity. So it is not equivalent to the < operator. If you used < with a floating-point type, you would have to consider how to treat NaN also. This is n...
Is it better practice to use String.format over string Concatenation in Java?
...thout requiring a recompile of the executable to account for the different ordering. With argument positions you can also re-use the same argument without passing it into the function twice:
String.format("Hello %1$s, your name is %1$s and the time is %2$t", name, time)

You shouldn't rely on the order of elements by using prev or next. Just use the for attribute of the label, as it should correspond to the ID of the element you're currently manipulating:
var label = $("label[for='" + $(this).attr('id') + "']");

Are Duplicate HTTP Response Headers acceptable?
...each subsequent field-value to the first, each
separated by a comma. The order in which header fields with the same
field-name are received is therefore significant to the interpretation
of the combined field value, and thus a proxy MUST NOT change the
order of these field values when a mess...
What is a elegant way in Ruby to tell if a variable is a Hash or an Array?
...
This won't work if your code is dependent on the ordering of the data(e.g. if you are using each_with_index). The order of the elements is implemented differently between hashes and arrays and it is different between ruby versions.(intertwingly.net/slides/2008/oscon/ruby19/...
