-[Cody](#cody) added the [alternate
-versions](2012/omoikane/index.html#alternate-code) which will, if no arg is
-specified, read in the program itself, rather than `/dev/urandom`. This is
-mostly useful for those without a `/dev/urandom` device file, which the author
-pointed out as being a problem, but which is the default for the entry . The
-second alternate version is like the first except that it also sets binary mode
-on `stdin` and `stdout` which should theoretically make it work in Windows. This
-comes from the author's remarks.
-
-Cody also added the [try.sh](%%REPO_URL%%/2012/omoikane/try.sh) and
-[try.alt.sh](%%REPO_URL%%/2012/omoikane/try.alt.sh) scripts.
