<h1>JMRI: 2007 User Poll</h1>
|
|
In late May and early June 2007, we ran three polls in the now deprecated Yahoo <a href=
|
|
"http://groups.yahoo.com/group/jmriusers">jmriusers group</a> to learn more about what our
|
|
users are actually using. This page reports the results.
|
|
<p>There's likely to be a selection bias in the responses. People who are actively involved
|
|
with JMRI are more likely to subscribe to the jmriusers group, which was necessary to learn
|
|
of the poll. They are possibly more likely to reply to the poll, and more likely to have a
|
|
more recent version. We should take this into account when using the results.</p>
|
|
|
|
<p>In the sections below, we summarize and interpret the results. The complete <a href=
|
|
"#raw">raw data</a> is available at the end of the page.</p>
|
|
|
|
<h3>JMRI Version</h3>
|
|
The poll asked which version of JMRI people were using. The results, in decreasing order of
|
|
popularity, were:
|
|
<ol>
|
|
<li>74% 1.7.6 (The most recent test release at that time)</li>
|
|
|
|
<li>7% 1.7.5</li>
|
|
|
|
<li>5% 1.6.1 (The most recent production release)</li>
|
|
|
|
<li>5% I build my own version from the code</li>
|
|
|
|
<li>4% 1.7.4 and 1.7.3 combined</li>
|
|
|
|
<li>0% Test releases in the 1.7 series before 1.7.3</li>
|
|
</ol>
|
|
One respondent (of 266) reported using "1.5 (any)", and one reported "1.4 (any)". These may
|
|
be confusions with the Java version.
|
|
<p>Note that 1.7.6 was the most recent test release, but it was quite old. The most recent
|
|
production release, 1.6.1, was very old. This may have caused more people to use the most
|
|
recent test release(s) than we would have normally found. The poll's selection bias may also
|
|
have resulting in more people listing the most recent test release(s) than is true of the
|
|
user population as a whole, thus understating the number of people who just download the more
|
|
recent production version and run.</p>
|
|
|
|
<h3>Java Version</h3>
|
|
The poll asked which Java version JMRI was using. The results, in decreasing order of
|
|
popularity, were:
|
|
<ol>
|
|
<li>35% 1.5</li>
|
|
|
|
<li>33% 1.6</li>
|
|
|
|
<li>20% 1.4</li>
|
|
|
|
<li>10% 1.7</li>
|
|
|
|
<li>0% 1.3 or earlier</li>
|
|
</ol>
|
|
Out of 159 responses, there were zero users of Java 1.3 or earlier. This is somewhat
|
|
inconsistent with smallbut non-zero number of people who said they are using JMRI on original
|
|
Macintosh computers, which use Java 1.1, but the response to this poll was small than to the
|
|
operating system poll.
|
|
<p>It's possible that 10% of JMRI users have downloaded test distributions of Java 1.7 from
|
|
Sun, but since Java 1.7 is not generally released yet it seems more likely that some of those
|
|
responses are confusions with the JMRI release number. This in turn implies that the Java 1.6
|
|
number might be a little inflated by the same mechanism.</p>
|
|
|
|
<h3>Operating System Version</h3>
|
|
The poll asked which operating system and version was being using to run JMRI. The results,
|
|
in decreasing order of popularity, were:
|
|
<ol>
|
|
<li>52% Windows XP (including SP1, SP2, Home and Professional)</li>
|
|
|
|
<li>13% Windows 98</li>
|
|
|
|
<li>11% Windows 2000</li>
|
|
|
|
<li>9% Mac OS X - 10.4 or later</li>
|
|
|
|
<li>8% Linux - combined types, with no clear leader among them</li>
|
|
|
|
<li>3% Windows Vista</li>
|
|
|
|
<li>2% Windows Millenium Edition</li>
|
|
</ol>
|
|
There were no respondents using Windows x64, Windows NT, or Windows 95. One respondent used
|
|
"Windows Server (Any, including 2003)", and one "Windows (Other, including CE)".
|
|
<p>There were four respondents (1.5%) who used Macintosh OS 8.6, 9.0 or 9.1. All of the Mac
|
|
OS X respondents were using version 10.3 (4 votes) or later (20 votes).</p>
|
|
|
|
<p>Among only Linux varients, the responses were:</p>
|
|
|
|
<ul>
|
|
<li>5 Red Hat, including Centos</li>
|
|
|
|
<li>4 Ubuntu</li>
|
|
|
|
<li>4 Debian</li>
|
|
|
|
<li>4 SUSE</li>
|
|
|
|
<li>2 Other</li>
|
|
|
|
<li>1 Gentoo</li>
|
|
</ul>
|
|
|
|
<p>Among other operating systems, there were no respondents indicating they used OS/2, or
|
|
either "Other Unix-based" or "Other non-Unix-based". One respondent was using Solaris.

<h3>Raw Data</h3>
|
|
The poll results are available from the <a href=
|
|
"http://groups.yahoo.com/group/jmriusers/polls">poll page</a> of the deprecated <a href=

|
|
<h4>Operating System Poll</h4>
|
|
The poll prompt was:
|
|
<p><em>Which operating system do you run JMRI on? We'd like to know this to improve our
|
|
testing and development. You can pick as many choices as you want, but please only select
|
|
ones that you are using now, or are actually running on a computer that you're likely to put
|
|
JMRI on soon.</em>

<h4>Java Version Poll</h4>

The poll prompt was:

<p><em>Which version of Java do you use when running JMRI? If you're not sure, you can find
|
|
out by starting DecoderPro and looking at the 2nd line on the startup window. It'll say

something like "Java version 1.5.0_07 (en_US)"; we just want the first digits, e.g. 1.5. We
