I've been trying to get rid of a bunch of underfull `\hbox` warnings in my cv. A minimal example of what I am dealing with is as follows:

```
\documentclass{article}
\usepackage{calc}
\setlength{\parindent}{0pt}

\newcommand\Job[3]{{\bf #1}, #2\\ #3}

\newcommand\LongestDate{\widthof{7777 (Spring)}}
\newcommand\DatedItem[2]{
    \begin{tabular*}{\linewidth}[t]{@{\hspace{0.25in}}p{\LongestDate}@{\hspace{0.125in}}p{\linewidth - \LongestDate - 0.375in}@{}}
            #1 & {\raggedright #2}
    \end{tabular*}}

\begin{document}

\DatedItem{2013--}{\Job{Rice University}{Houston, TX}{Associate Professor}}

\end{document}

```

I've tried inserting `\hfill`'s in various places (like before all the `\\`) and also adding a bunch of `\raggedright`'s. But nothing seems to get rid of the warnings. I should remark that everything is typeset like I want -- I just want it to compile with no warnings!
