<h2>Real-Time Lunch</h2>
<p>RT Lunch is a weekly seminar focussed on current research in real-time systems and related fields. It is open to all and a great way to get to know UNC's Real-Time Systems group. <em>Y'all should come!</em>
</p>
<p>We also have a weekly <a href="litmuslunch.html">LITMUS<sup>RT</sup> Lunch</a> as well.</p>
<h2>Mailing List</h2>
<p>RT Lunch is coordinated via our mailing list <a href="mailto:rtlunch@listserv.unc.edu">rtlunch@listserv.unc.edu</a>. This list is also used to share other relevant news and to coordinate upcoming events. All members of the Real-Time Systems group should subscribe to this list.
</p>
<h2>Time and Location</h2>
<p>
For the Spring 2011 semester, RT Lunch is held each Wednesday from 12:30 to 1:30 in SN 120.</p>

<h2>Pre 2008</h2>
<p>Real-Time Lunch has been around forever (<em>i.e.</em>, longer than the current grad student generation), but the old schedules have been lost in the sands of time. Rumor has it that the talks were great, though. ;-)</p>
