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.

3. Why do I have to +worry about choosing a "role"?

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. -

4. What kind of +computer and operating will this work on?

The operating system LON-CAPA runs on is the Linux operating -system. LON-CAPA relies on an Intel-based architecture. +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. +

+

+For full-time, classroom usage, an adequate LON-CAPA server +should be/have: +

+
    +
  • a multiprocessor machine,
    • +
  • a CPU speed of 1 gigahertz,
    • +
  • a gigabyte of memory,
    • +
  • and at least 40 to 80 gigabytes of hard disk space.
    • +
+

+A lesser machine can be used for toying around with LON-CAPA +(LON-CAPA will run for a single user on most any machine). +

+

+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. +

+

+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.

-No. +We like to think of high web server usage as "a good problem" though.. :)

4b. Will this work on Mac OS X? +

-No. +Active development has begun for supporting LON-CAPA on FreeBSD version 4.7.

-
5. What does LON-CAPA stand for? +
4b. Will this work on +Mac OS X? +

+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. +

+
4c. Will this work on +an old SPARC, Solaris, SGI, NeXT, or DEC machine that is collecting cobwebs in +my university's technology center? +

+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. +

6. Who wrote this +code? +

+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. +

+

+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, Kortemeyer, et. al..
