I have included code from others trusting that it would work, and that they would fix reported problems. And often that is true, there are quite a few faithful contributors. But sometimes someone just wants to get his feature in, and as soon as the things he uses are working, he disappears. And then I end up having to fix problems. These days I’m a lot more careful about including new features. Especially when it’s complex and interferes with several existing parts of the code. I’m insisting more often on writing tests and documentation before including anything.

And that’s where the real problem may lie—not with student semi-literacy but with that of their teachers.

However, we recognise there are some differing opinions as well as practical considerations around the use of partial cookie walls and we will be seeking further submissions and opinions on this point from interested parties.

Based on Department of Homeland Security estimates, Trump’s proposed wall will cost nearly $22 billion, span 1,250 miles, and take more than three years to build.
