The debugging interface of Eclipse with a program suspended at a breakpoint. Panels with stack trace (upper left) and watched variables (upper right) can be seen. In software development, a breakpoint is an intentional stopping or pausing place in a program, put in place for debugging purposes. It is also sometimes simply referred to as a pause
The breakpoint can be important in decision making [1] The figures illustrate some of the results and regression types obtainable. A segmented regression analysis is based on the presence of a set of ( y, x ) data, in which y is the dependent variable and x the independent variable .
Notably, the delivery need not be made by the clerk who took the order. A callback need not be called by the function that accepted the callback as a parameter. Also, the delivery need not be made directly to the customer. A callback need not be to the calling function. In fact, a function would generally not pass itself as a callback.
A deferred is an instance of a class designed to receive and process a result which has not been computed yet, for example because it is based on data from a remote peer. Deferreds can be passed around, just like regular objects, but cannot be asked for their value. Each deferred supports a callback chain.
Time travel debugging or time traveling debugging is the process of stepping back in time through source code to understand what is happening during execution of a computer program. [1]
# This function has no guard clause def f_noguard (x): if isinstance (x, int): #code #code #code return x + 1 else: return None # Equivalent function with a guard clause. Note that most of the code is less indented, which makes it easier to read and reason about def f_guard (x): if not isinstance (x, int): return None #code #code #code return x + 1

Symmetric—there is no difference between the client and the server—both can serve. The only different aspect is that the client is usually the side that initiates the action. Being symmetric, for example, allows the client to pass callback functions to the server. Transparent—remote objects look and behave the same as local objects would.
