I would like to try at least one or two programs in the category of "geometry exploration programs."

It's funny that MS uses this stupid scheme to detect pirate software.

Atheros HAL

I came acroos to read this paper:
http://www.cse.iitk.ac.in/users/braman/students/2006/narasima.html

In this paper, the author implemented a 802.16-like MAC protocol on top of Atheros Madwifi driver. They were able to:

o Disable the backoff mechanism on Atheros card
o Partly disable virtual sense by increasing the CCA theshold
o Nullify DIFS, SIFS

These functions are not available in HAL. Thus we must set the hardware registers bypassing HAL. I also found the OpenHAL is actually inside the source of OpenBSD. I will look at the Open HAL code and continue to investigate how to achieve these goals.

Eclipse Copys SVN directories to Output folder

Problem:
During the building process of Eclipse, it will copy everything from source folders to a output folder. However, if the output folder is overriden to be some directory also under svn root, problem occurs because svn will be confused to produce incorrect output, such as restoring source files under the output directory.


Solution:
Set the output folder to somewhere out control of svn.
