Getting Started

To get started, you will need a UT Physics linux cluster account. If you don't already have such an account, you can apply for one by visiting the Physics Computer Group in RLM 7.126.

Next, your account must be put in the cps group. You can accomplish this by sending an email to help@physics.utexas.edu asking to be added to the cps group, or by requesting this on the account application when applying for a new account.


Editing Problems

To edit questions, log into one of the linux machines, linux1.ph.utexas.edu through linux13.ph.utexas.edu. We recommend using ssh, but if you are inside RLM you can use telnet if needed. For example:

ssh yourusername@linux1.ph.utexas.edu
login, etc.

If this is your first time, get all the files into your account:

get

The above will create a directory called sources with all the Classwork problem source files inside it.

If this isn't your first time, you should update the files in your account before beginning. You can update the files at any time. To update the files:

cd ~/sources
get

Now you can edit the file filename.tex and create a new question file.

vi filename.tex
tt

If you have TeX errors, edit the file again tofix them, and then run tt again. Repeat the process until all the errors have been resolved.

To view the file you have just edited use your browser and the URL

http://www.ph.utexas.edu/~cps/filename.pdf

If needed, re-edit the file and make corrections, run tt again, and check the results, until you are satisfied with your work.


Classwork Editing Commands

The following commands, located in /usr/local/bin on the linux machines, can be used when editing Classwork problems.

tg
use ghostview to put a picture of the result on your terminal. You must have X windows setup and working properly to use this.

get
get/update all source files from repository to your account for editing.

del
removes the file from your account and the repository.

ren
renames a file in your account and the repository.

pp
puts the powerpoint file into http://www.ph.utexas.edu/~cps/public_html/ and saves the .ppt file to the repository.

tt
puts the pdf file into http://www.ph.utexas.edu/~cps/public_html/ and saves the .tex and .eps file(s) if any to the repository.


File Structure of a Question

Classwork Problems are TeX files. They should always have the following structure.

\input cps.tex

------------------- (Paragraph setting up the problem)

------------------- (The Figure)

------------------- (Question)

\vskip8pt           (if space allows)

Using the Problems from the Web

To access the Classwork problems, simply point your web browser to the URL

http://www.ph.utexas.edu/~cps/

From here, you can select the problem category (e.g. biology, math, physics, etc) by simply clicking on the appropriate link. Once inside the appropriate category, you will find two more links: projector and transparencies.

Projector files are for using with a video projector in the multi-media classrooms. They are formated into two pages, with the question on the first page, and the answer/solution on the second page. This is so that you can project the questions and answers on the screen independently.

Transparencies are for printing onto transparencies and then using with a standard overhead projector. They are formated as a single (divided) page, so you can cover the bottom answer/solution section until needed (and then reveal it).

Once you select one of the two formats, you will shown a list of all the Classwork problem files for that category. Simply click on the desired file name to display that problem.

Note: Since problems are PDF files, you will need a PDF viewer installed on the machine in order to actually view the files on your screen or to display them on the video projector.
