The first was posted 4 years ago, with many points and little discussion https://news.ycombinator.com/item?id=28490238 https://news.ycombinator.com/item?id=28490238 so it may be reposted now. The second one was never posted... Both are good to be posted, but I recommend to post one and wait a month to post the other so no one get annoyed.
