The author claims that parallel has been replaced by xargs -P. While some of what parallel does can be replicated by (modern) xargs, it can't totally replace parallel (for example, parallel can do load limiting). However, there is the much more powerful/flexible GNU implementation of parallel <https://www.gnu.org/software/parallel/>. I don't know which came first. Beware that some of the flags are different!
The author claims that mispipe has been replaced by shell features (in the case of Bash, "set -o pipefail"), and I agree with that. But beware that pipefail has slightly different semantics than mispipe! (the mispipe manpage explains this).
The author neglects to mention/realize that the behaviour of pee can be replicated with tee and Bash features:
tee >(cmd1...) >(cmd2...) >(cmd3...) >/dev/null
Also, there is another implementation of chronic called cronic <http://habilis.net/cronic/>. I believe cronic came first, but I'm not sure about that.
