for cpp_file in *.cpp; do gcc -c $$cpp_file & done; wait This gives much finer control than make -j.

There is one very important reason for enabling job control to be useful inside scripts: the side-effect it has of placing background processes in their own process groups. This makes it much, much easier to send signels to them and their children with one simple command: kill -<signal> -$pgid. All other ways of dealing with signaling entire trees of processes either involve elaborate (sometimes even recursive) functions, which are often bugnests, or risk killing the parent in the process (no pun intended).

These tests should only be used when: the functionality/component being tested is small the internal state of the objects/database needs to be tested it cannot be tested at a lower level

Thanks, this was just what I was looking for! This is a perfect appropriate use of instance_eval. I do not understand the nay-sayers. If you already have your array in a variable, then sure, a.reduce(:+) / a.size.to_f is pretty reasonable. But if you want to "in line" find the mean of an array literal or an array that is returned from a function/expression — without duplicating the entire expression ([0,4,8].reduce(:+) / [0,4,8].length.to_f, for example, is abhorrent) or being required to assign to a local, then instance_eval option is a beautiful, elegant, idiomatic solution!!

instance_eval is analogous to using tap, yield_self, … when you are dealing with a chain of method calls: do use it whenever it's appropriate and helpful! And in this case, I absolutely believe that it is.

instance_eval lets you run the code while only specifying a once, so it can be chained with other commands. I.e. random_average = Array.new(10) { rand(10) }.instance_eval { reduce(:+) / size.to_f } instead of random = Array.new(10) { rand(10) }; random_average = random.reduce(:+) / random.size

Honeybadger isn't a single page app, and it probably won't ever be. SPAs just don't make sense for our technical requirements.
