This is great but it looks like <a href="https://news.ycombinator.com/item?id=36102419" rel="nofollow">https://news.ycombinator.com/item?id=36102419</a> was submitted earlier and has more background info, so I put that one in the SCP instead (see <a href="https://news.ycombinator.com/item?id=26998308" rel="nofollow">https://news.ycombinator.com/item?id=26998308</a>).<p>I'm sorry! It's on my list to implement karma sharing for cases like this, but I haven't gotten to it yet.
