So, I'm a bit annoyed today... you see, I got over 100 reputation today for answering a question.
Why am I annoyed? Because it is for the almost obvious answer I supplied to the river flowing out of an ocean question. I'm glad people liked that answer. BUT... I really hoped people would notice the answer that I finally managed to put together for the highly intriguing "can you hack a computer with an arrow?" question.
Because, you see, when the question was first posted, I put up a good answer (I thought; community seemed to agree) about how it could be accomplished. But I felt... empty. Like the question lingered on the edge of possible. So I pulled some resources at work and, lo, I think it really is feasible with some very specific hardware (which is within the scope of the question!).
Unfortunately, people have already read that question, and they don't seem likely to go back to it later. So after watching it go a full day without being noticed, I decided to write this meta purely for the humble brag of promoting a damn cool answer because, well, maybe someone will actually go ahead and make the movie the question inspires! So here's my updated answer!
