+				<h3>Special Thanks</h3>
+				<p>Ongoing development of Typica is made possible through the
+				generous financial contributions from the following:</p>
+				
+				<p>Pinnacle Coffee Roasting</p>
+				
+				<h3>Get Involved</h3>
+				<p>Typica has reached a point in its development where it can
+				be considered mature with a feature set appropriate for many
+				coffee roasting firms. There is, however, considerable variety
+				among roasting firms in the equipment used, roasting styles,
+				process traceability requirements, languages understood, and
+				other preferences. There is also still considerable room for
+				improvement in many areas. The development of Typica has been
+				on a budget of approximately $0, but software development is
+				not without cost. This is especially the case for cross
+				platform development of software that interfaces with external
+				hardware. These are some of the things that could be done with
+				additional funding:
+					<ul>
+						<li>Improve development and testing infrastructure.
+						This would allow more complete testing of release
+						candidates on all platforms and greatly increase the
+						quality and speed at which new releases could be made
+						available.</li>
+						<li>Purchase additional measurement devices. Interest
+						has been expressed in using many types of hardware not
+						currently supported in Typica. Some of these
+						suggestions are quite reasonable and the only reason I
+						am not able to include support for them is simply that
+						I do not have a sample of the hardware to test my code
+						against.</li>
+						<li>Pay for web hosting. While the Internet allows
+						free software to be distributed cheaply, this is not
+						without cost.</li>
+						<li>Allow more development time. As of this writing,
+						nobody has contributed any improvements to Typica's
+						program code. This has all been designed and written
+						by a single person working on it as time is available.
+						Many of the planned improvements require nothing beyond
+						time to plan an implementation, to write the program
+						code, to integrate it with the rest of the program, and
+						to test that the feature is sound. With sufficient
+						sustained funding it would be possible to devote more
+						time to continuing development, resulting in a more
+						rapid release of features and other improvements to
+						Typica.</li>
+					</ul>
+				</p>
+				<p>Financial assistance toward these ends can be sent (checks
+				payable in US dollars preferred) to:</p>

 @** A representation of temperature measurements.

 @<ZoomLog Implementation@>=
 void ZoomLog::newMeasurement(Measurement measure, int tempcolumn)
 {
+	@<Synthesize measurements for slow hardware@>@;
 	model_ms->newMeasurement(measure, tempcolumn);
 	if(lastMeasurement.contains(tempcolumn))
 	{
 	m->newMeasurement(measure, tempcolumn);
 }
 
+@ Some measurement hardware in use cannot guarantee delivery of at least one
+measurement per second. This causes problems for the current |ZoomLog|
+implementation as, for example, if there is no measurement at a time where
+the seconds are divisible by 5, there will be no entry in that view. This can
+result in situations where the |ZoomLog| at its default view of one measurement
+every 30 seconds might not display any data at all aside from the first
+measurement, the last measurement, and any measurement that happens to have an
+annotation associated with it. The solution in this case is to synthesize
+measurements so that the |ZoomLog| thinks it gets at least one measurement
+every second.
+
+The current approach simply replicates the last measurement every second until
+the time for the most recent measurement is reached, however it would likely be
+better to interpolate values between the two most recent real measurements as
+this would match the graphic representation rather than altering it when later
+reviewing the batch.
+
+@<Synthesize measurements for slow hardware@>=
+if(lastMeasurement[tempcolumn].time() < measure.time())
+{
+	QList<QTime> timelist;
+	for(QTime i = lastMeasurement[tempcolumn].time().addSecs(1); i < measure.time(); i = i.addSecs(1))
+	{
+		timelist.append(i);
+	}
+	for(int i = 0; i < timelist.size(); i++)
+	{
+		newMeasurement(Measurement(measure.temperature(), timelist[i], measure.scale()), tempcolumn);
+	}
+}
+
 @ New to \pn{} 1.4 is the concept of a current column set. This was added to
 improve support for devices where measurements on different data series may not
 arrive at exactly the same time and for multi-device configurations where
