CallbackMod:start(normal, Args). It will also call
CallbackMod:stop(Args) when stopping it.
It should be changed to:

CallbackMod:start(normal, Args). This function's return value will be
used when OTP will call CallbackMod:stop(StartReturn) when stopping your
application.

The line which reads:
"Note that closing an accept socket will close that socket alone, and closing a listen socket will close all of the related accept sockets"

In the third paragraph under "Test Generators," the sentence that reads:
"It’s called that because, secretly, the underlying implementation of ?_assert(A == B) is fun() -> ?assert(A,B) end; that is to say, it’s a function that generates a test."
Should instead read:

some_test2_() should be called some2_test_() in order to run, and a
comma should be added after foreach.

some_tricky_test2_() should be called some_tricky2_test_() in order to
run.

The line of code in the section titled "Implementation Details" which reads:
?MODULE = ets:new(regis, [set, named_table, protected]),
Should instead read:

The text reads:
By default, the heart-beat delay (also called tick time) is set to 15 seconds, or 15,000 milliseconds.
It should read:
By default, the heart-beat delay is set to 15 seconds, or 15,000 milliseconds. After 4 failed heart-beats, a remote node is considered dead. The heart-beat delay multiplied by 4 is called the tick time.
Page 506:
In the code block in the middle of the page:
{logdir, [all_nodes, master], "./logs/"}.
Should be replaced with:
{logdir, all_nodes, "./logs/"}.
{logdir, master, "./logs/"}.
And the sentence in the second to last paragraph of the page which reads "To truly include all nodes, [all_nodes, master] is required" should instead read: "To truly include all nodes, both all_nodes and master are required."
Page 545:
The first line of code in the middle of the page which reads:
foo(X) when is_integer(X) -> X + 1.
Should end with a semicolon and instead read:
