<hr />1. <font color="blue"><font size="+1"><a name="q1" />What is TtH and how |
|
do I know I have it?</font></font> |
|
<p> |
|
TtH = TeX-to-HTML. |
|
You should have a file called <tt>tth.so</tt> on your system. If you do not |
|
have it (should be located somewhere underneath /usr/lib/perl5), then you |
|
should download and install the binary |
|
<a href="http://install.lon-capa.org/resources/tth.so"> |
|
http://install.lon-capa.org/resources/tth.so</a> |
|
into your /usr/lib/perl5/site_perl/5.???/ directory (5.??? corresponds |
|
to the version number of your perl distribution). |
|
</p> |
|
<hr />2. <font color="blue"><font size="+1"><a name="q2" />So I think I'm done |
|
with the LON-CAPA installation. |
|
Now what do I do? How do I begin?</font></font> |
|
<p> |
|
You will first need to set up a domain coordinator on your machine. |
|
See loncapa/doc/how_to_domain_coordinator.txt in your CVS repository checkout. |
|
After this, it is time to play with the interface. We do not |
|
yet have a user manual, but |
|
<a href="mailto:felicia@lon-capa.org">Felicia</a> is helping answer |
|
questions related to the LON-CAPA web interface. |
|
</p> |
|
<hr />3. <font color="blue"><font size="+1"><a name="q3" />Why do I have to |
|
worry about choosing a "role"?</font></font> |
|
<p> |
|
A critical feature of the LON-CAPA interface is the idea that a user |
|
must select a role before doing anything further inside the educational |
|
system. |
|
</p> |
|
<hr />4. <font color="blue"><font size="+1"><a name="q4" />What kind of |
|
computer and operating will this work on?</font></font> |
|
<p> |
|
The operating system LON-CAPA runs on is the Linux operating |
|
system (RedHat 7.3 is the supported linux distribution). |
|
LON-CAPA relies on an Intel-based architecture. In order to |
|
move beyond this state of affairs, we are beginning to develop |
|
a BSD-based solution, as well as a set of diagnostic scripts |
|
which should verify LON-CAPA's performance on any computer platform. |
|
</p> |
|
<p> |
|
For full-time, classroom usage, an adequate LON-CAPA server |
|
should be/have: |
|
</p> |
|
<ul> |
|
<li>a multiprocessor machine,</li> |
|
<li>a CPU speed of 1 gigahertz,</li> |
|
<li>a gigabyte of memory,</li> |
|
<li>and at least 40 to 80 gigabytes of hard disk space.</li> |
|
</ul> |
|
<p> |
|
A lesser machine can be used for toying around with LON-CAPA |
|
(LON-CAPA will run for a single user on most any machine). |
|
</p> |
|
<p> |
|
LON-CAPA servers experience significant peaks of activity |
|
before a homework submission deadline. To support these critical |
|
peaks of activity, it is strongly advised that LON-CAPA machines |
|
fit the above recommendation. |
|
</p> |
|
<p> |
|
If thousands of students start accessing the box as a web server... |
|
you may want to consider more options. The design of the LON-CAPA |
|
system is to naturally and transparently load-balance on multiple |
|
computer clusters. So, a simple solution for running an entire |
|
college campus is to just have an adequate plurality of LON-CAPA |
|
servers rather than a single, particularly monstrous server. |
|
</p> |
|
<p> |
|
We like to think of high web server usage as "a good problem" though.. :) |
|
</p> |
|
<hr />4a. <font color="blue"><font size="+1"><a name="q4a" />Will this work on |
|
BSD?</font></font> |
|
<p> |
|
Active development has begun for supporting LON-CAPA on FreeBSD version 4.7. |
|
</p> |
|
<hr />4b. <font color="blue"><font size="+1"><a name="q4b" />Will this work on |
|
Mac OS X?</font></font> |
|
<p> |
|
No. Plans for Mac OS X involve waiting for completion of a FreeBSD version 4.7 |
|
solution, as well as allowing Mac OS X more time to mature within the freeware |
|
community. |
|
</p> |
|
<hr />4c. <font color="blue"><font size="+1"><a name="q4c">Will this work on |
|
an old SPARC, Solaris, SGI, NeXT, or DEC machine that is collecting cobwebs in |
|
my university's technology center?</font></font> |
|
<p> |
|
No. The needs for predictable performance of a LON-CAPA system cause us |
|
to emphasize support on a restricted set of platforms. We welcome developers |
|
who would like to create porting solutions, however based on our timeline, |
|
you are even more strongly encouraged to help develop the actual educational |
|
software technology seen by students and instructors. |
|
</p> |
|
<hr />5. <font color="blue"><font size="+1"><a name="q5" />What does LON-CAPA |
|
stand for?</font></font> |
|
<p> |
|
The Learning Online Network with Computer-Assisted Personalized Approach. |
|
</p> |
|
<p> |
|
An eclectic variant is: Look! Our New Car Answers Pizza Appetites. |
|
</p> |
|
<p> |
|
Or something. |
|
</p> |
|
<hr />6. <font color="blue"><font size="+1"><a name="q6" />Who wrote this |
|
code?</font></font> |
|
<p> |
|
The ultimate goal of LON-CAPA is to be a software initiative with a |
|
sense of ownership spanning the entire academic and freeware community. |
|
As such, LON-CAPA is progressing toward a piece of code that is not |
|
characterized by a set of individual authors or any measure of territoriality. |
|
</p> |
|
<p> |
|
To date, LON-CAPA has received code contributions from a growing |
|
number of academic institutions and freeware contributors. LON-CAPA first |
|
originated at Michigan State University in 2000 based on a grant funded |
|
initiative, <i>Kortemeyer, et. al.</i>. |
|
</p> |
|
<hr />7. <font color="blue"><font size="+1"><a name="q7" />Where is this |
|
software being used?</font></font> |
|
<p> |
|

|
<hr />8. <font color="blue"><font size="+1"><a name="q8" />What are current |
|
plans for the installation?</font></font> |
|
<p> |
|
We have been able to run LON-CAPA on RedHat 6.2, 7.1, 7.2, Debian, and |
|
Mandrake. |
|
</p> |
|
<hr />9. <font color="blue"><font size="+1"><a name="q9" />How do I |
|
upgrade?</font></font> |
|
<p> |
|
You must use CVS over the network. |
|
Please click on the upgrade button at the top of this web page. |
|
</p> |
|
<hr />10. <font color="blue"><font size="+1"><a name="q10" />What are |
|
RPMs?</font></font> |
|
<p> |
|
Software packages that are (usually) very easy to install. RPM stands |
|
for RedHat Packaging Manager software package. |
|
</p> |
|
<hr />11. <font color="blue"><font size="+1"><a name="q11" />How do I know |
|
this will be a secure solution for my users?</font></font> |
|
<p> |
|
LON-CAPA is distributed without warranty as described in the |
|
<a href="http://install.lon-capa.org/docs/license/index.html">license</a>. |
|
</p> |
|
<p> |
|
We do think our security strategy is fairly robust. Important communications |
|
are encrypted and the server-client validation is instantiated in such |
|
a way as to prevent any remotely conceivable kind of spoofing. |
|
</p> |
|
<hr />12. <font color="blue"><font size="+1"><a name="q12" />How do I |
|
contribute code?</font></font> |
|
<p> |
|
Send a diff to <a href="mailto:lon-capa-dev@mail.lon-capa.org"> |
|
lon-capa-dev@mail.lon-capa.org</a>. It helps if you give it context |
|
with the -C option. For example, |
|
</p> |
|
<pre> |
|
diff -u -C3 doc/build/faq.html doc/build/faq.html~ | mail lon-capa-dev@mail.lon-capa.org |
|
</pre> |
|
<hr />13. <font color="blue"><font size="+1"><a name="q13" /> |
|
Is LON-CAPA owned by any umbrella company?</font></font> |
|
<p> |
|
No and hopefully never. That is not what we are about. We are about a |
|
freeware-community oriented approach where the software features are directly |
|
specified by the involved academic institutions and instructors. |
|
</p> |
|
<hr />14. <font color="blue"><font size="+1"><a name="q14" /> |
|
What are the costs?</font></font> |
|
<p> |
|
Time & Money. You and/or somebody else needs the time to learn how to use |
|
the LON-CAPA system. You and/or somebody else needs the money to set up and |
|
maintain a working computer server(s) for your institution. |
|
</p> |
|
<p> |
|
More importantly, if your institution wants a sound future and a |
|
increased ability to configure the LON-CAPA software, we recommend |
|
that you assume some responsibility for contributing code to the |
|
freeware project. |
|
</p> |
|
<hr />15. <font color="blue"><font size="+1"><a name="q15" /> |
|
What kind of computer do I need?</font></font> |
|
<p> |
|
You need a RedHat 7.3 Intel-compatible computer. |
|
For more information on RedHat compatible hardware, visit |
|
<a href="http://hardware.redhat.com/hcl/">http://hardware.redhat.com/hcl/</a>. |
|
We do not currently support the SPARC, SGI, Macintosh, or other hardware |
|
architectures. |
|
</p> |
|
<hr />16. <font color="blue"><font size="+1"><a name="q16" /> |
|
Where can I learn more about the technical |
|
ideas surrounding the LON-CAPA project?</font></font> |
|
<p> |
|
You will find the technical manual to be very handy; please visit |
|
<a href="http://www.lon-capa.org/technical.html"> |
|
http://www.lon-capa.org/technical.html</a>. |
|

|
<hr />17. <font color="blue"><font size="+1"><a name="q17" /> |
|
How are you similar or different to |
|
WebCT, Blackboard, etc?</font></font> |
|
<p> |
|
I would suggest two major differences: |
|
</p> |
|
<ol> |
|
<li>In LON-CAPA, the <strong>user</strong> is the fundamental data object. |
|
Other educational software systems seem to focus on the <strong>virtual |
|
classroom</strong> as the fundamental data object.</li> |
|
<li>I look at it like this. Many strictly profit-based enterprises aim to |
|
significantly please 80% of their users. LON-CAPA started out, in the |
|
beginning, aiming for a much higher percentage since the whole project |
|
was about doing what no one had done before. |
|
</li> |

</ol> |
