Everyone needs 43 things.

This page contains various notes and code snippets that I have needed and used while developing. Hope that they can be of some assistance. If there are any questions, comments, fixes, etc, please let me know (jcorso@cs.jhu.edu).
note that I have organized them alphabetically by category...

bibliography and typesetting

• YapBib - Your Annotated Personal Bibliography.It is a program to aid you in keeping track of your literature/bibliography. Exports to bibtex format.
• How do I configure teTeX 1.0 so that it can process Mathematica-generated LaTeX documents?
• The easiest way to use latex/tex via the command-line on the MAC OS X is with the tetex package. You can download the i-installer program here and then install the tetex packages. There are some gui's also, OzTeX and TexShop (you need tetex for texshop but not oztex). A good reference site is MAC-TEX
  I have not tried it yet but Lyx is ported to MAC OS X: here
• The hyperref package is a great way to enhance the output of your latex files when published in pdf form. It will create cross-links to the refernces for instance, and does much more. Here is the manual.
• some templates for Latex2e files (somewhat outdated) here
• A sample file that demonstrates how to use color in latex [ tex(html)| tex| pdf result] .

debugging

• DebugMalloc Library - An indispensable debugging tool for all the malloc hairpulling bugs. All you need to do is #include dmalloc.h and then link -ldmalloc and stubs that point to the debug malloc calls are automatically placed whereever you call malloc... Then drop core and launch gdb.
• Valgrind - A super memory debugger/program analyzer that emulates the x86 instruction set and runs your process in a virtual machine allowing it to immediately detect the source of many errors.

geometry

• Parametric Plotting In GNUPLOT:

  gnuplot> set parametric        
  
          dummy variable is t for curves, u/v for surfaces
  gnuplot> plot t-sin(t),1-cos(t)
  gnuplot> plot [0:2*pi] t-sin(t),1-cos(t) 
  

graphics

• OpenGL texture mapping - a simple example
• OpenGL mip-mapping - a simple example
• glxwindow - A simple example of using the GLX protocol inside of a barebones Xwindow class so that you can do simple gl rendering in a program without making it slave to something like glut (sometimes functionality like this is important, otherwise, use glut or glvu).
• A tutorial on texture-mapped text output in OpenGL: here.

interaction (AR/VR)

• A hack that uses shared memory to feed a full-frame rate video stream (via XVision2) into an OpenGL/GLUT program
• We are using a 5DT Stereo HMD with X (v4). The correct modeline in order to operate the hmd at 640x480 VGA is

  25.2 640 656 752 800 480 490 492 525 +hsync -vsync

vision

• The world's most simple XVision2 program!
• A MATLAB interface to grabbing live video (analog/digital) images through XVision2. You do not need XVision2 to use this, but you will need a ieee1394 firewire camera installed or a BT Frame Grabber. This package has been implemented and tested on Linux 2.4 kernels and will not function in windows.
  download here
• Not getting full frame-rates on a machine that has the physical potential running 2.4.x... Make sure that MTRR is built into the kernel because it allows for fast memory transfers and is used by the X server.
• Here is a tarball for using the caltech matlab calibration toolbox and linking it up to 2 bttv cameras through XVision2. Then use IPP to yield a realtime rectified stereo stream. There is also some stereo disparity code, but it is not to good. download here

statistics Many good notes at Will Penny's page.

random

• An article about work-habits and procrastination.
• Postscript reference .
• Fix backspace in unix...type stty -a. Look at erase. Hit CONTROL-V and then your backspace key. If they do not match up, then type stty erase CONTROL-V,Backspace key. Now they should be matched up.
