Hi, I have a simple question about matrix/data frame manipulation. I have a data frame that looks a something like this X Y Z 1 0 "apples" -1 -1 "oranges" ... 0 -1 "bananas" and I'd like to pull out all the rows for which X and Y are (un)equal into a submatrix. How can I do that? Many thanks, Roger Levy

We still have MD5 as our default password hash, even though known-hash attacks against MD5 are relatively easy these days. We've supported SHA256 and SHA512 for many years now, so how about making SHA512 the default instead of MD5, like on most Linux distributions?
