Well the problem most likely lies in that you searched for Android in the Eclipse Marketplace, and you downloaded the latest SDK from Google’s website. Well, that is where the disconnect lies. The Eclipse Marketplace does’nt have the latest ADT plugin. You need to give Eclipse a different repository address to pull down the latest ADT plugin.

The directions are here, in the downloading section: http://developer.android.com/sdk/eclipse-adt.html#downloading

In the process of installing WireShark, i had to do some funny stuff.

After ChmodBPF folder into /Library/StartupItems, I then had to run the following lines on the command prompt to setup permissions for this startup folder to properly install:

cd /Library/StartupItems
sudo chown -R root:wheel ChmodBPF


libbluetooth.dev
libusb-dev

afterwards you can then go to the build directory of the lejos folder and run:

sudo ant

Happy robot making!

Setup nsswitch to dns:
# cp etc/nsswitch.conf etc/nsswitch.conf.original
# cp etc/nsswitch.dns etc/nsswitch.conf
# svcadm restart svc:/network/dns/client:default

Edit etc/nwam/llp to contain a static IP for your network device:
change the “nge0 dhcp” to “nge0 static 10.10.1.10/24”

Create the following file and add a gateway/router ip address to it on its own line:
etc/defaultrouter

Add your computers name to the hosts file:
edit etc/hosts and add: xx.xx.xx.xx computername

Enable the default networking:
svcadm enable svc:/network/physical:default

Restart computer

To sync the local software database with the database on the repositories, run the following on the command prompt:
apt-get update

To search for software/utilities:
# apt-cache search |NAME|

To install a package:
# apt-get install |NAME|

To remove a package:
# apt-get remove |NAME|

To upgrade all software to the latest version:
# apt-get upgrade

To upgrade the Operating System:#
# apt-get dist-upgrade

This command clears all the old installed packages from your system, these files are normally stored in:
# apt-get clean

So, it has been a while since I have posted anything. I have just been very busy with school, coming up with my research thesis and prepping for the Mid-Atlantic Collegiate Cyber Defence Competition(CCDC).

Speaking of the CCDC, we got 2nd place in the Qualifiers, and 1st place in the regional competition! So I am getting an all-expense paid trip to San Antonio, Texas to compete in the NATIONAL Cyber Defence Competition! What an amazing experience this has been, I’ve been receiving business cards from large corporations attempting to recruit me. I feel desired! lol.

The tone of this blog will now continue and focus on cyber defence stuff and my thesis, which deals with Context Aware Mobile Computing.

A small, simple autonomous wheel-based robot capable of self righting itself or extricating itself from awkward positions. I came up with this concept February 27, 2008.

The wheel hubs are domed to prevent the wheels from becoming stands that would keep the robot upright on its side.
The domed wheel hubs also provide a large traction area to also aid in the righting of the robot.
The eye of the robot extends and becomes a lever to help right the robot in an awkward position.
The extending eye also provides for a telescoping platform to aid in navigation and provide a base for the internal wireless antennae.

Mechanics:
Locomotion: Brushless motors
Telescoping Arm: Servo’s
Viewing Device: Undecided
Controller: Qwerk Controller -
# 200 MHz ARM9 RISC processor with MMU and hardware floating point unit
# 32 Mbytes SDRAM, 16 Mbytes flash memory
# Latest generation Xilinx Spartan 3E FPGA for custom I/O peripherals

3D design/Views

I currently have the Qwerk board and a wireless USB adapter for it. I need to create the base, acquire the servos, and find the right camera.

Well, I downloaded Cygwin from http://www.cygwin.com/. Cygwin is a Linux like environment that runs on Windows and it provides you many of the Linux tools through the use of cygwin1.dll, which is a Linux API emulation layer that provides Linux functionality. In this case allowing me to untar my kernel source and have access to it via the Cygwin app or my NetBeans IDE. How cool is that?

So for my memory and for those of you whom need the commands to untar your file:

The following tutorial assumes the name of your file is yourfile.tar.gz Replace with your actual filename.

1. From the terminal, change to the directory where yourfile.tar.gz has been downloaded.
2. Type tar -zxvf yourfile.tar.gz to extract the file to the current directory.

You can specify a different directory to extract to using -C parameter and a path to the directory as follows:

Example: tar -C /myfolder -zxvf yourfile.tar.gz

How to open or Untar a “tar” file in Linux or Unix:

1. From the terminal, change to the directory where yourfile.tar has been downloaded.
2. Type tar -zxvf yourfile.tar to extract the file to the current directory.
3. Or tar -C /myfolder -zxvf yourfile.tar to extract to another directory.

This semester I will be taking the following courses and will focus much of my writing dealing with these courses:
COSC600 – Advanced Data Structures and Algorithm Analysis
COSC519 – Operating System Principles
COSC578 – Database Management Systems
COSC650 – Computer Networks

The above courses are all core requirements, after this semester I get to choose the juicy stuff that I wish to delve into. COSC600 and COSC519 are of particular interest to me. I am very interested in delving deep into data structures/problem solving and I cant wait to dig into Linux, compile my own kernels and learn how to develop drivers, modules, and all the other neat stuff that comes along with Operating Systems.

Ps. If you are thinking about getting your masters or bachelors in computer science. Read the book “Code” from microsoft press. Its an amazing book that deals with the workings of a computer, how it gets coded, why we code the way we do… its am amazing wealth of information for aspiring computer scientists, everyday computer users, and programmers wanting a refresher on the basics.

Granted some of the difficulties lie on the fact that I have not taken a serious mathematics course in more than 8 years. Complicating things further, the professors first language is not english, and although he speaks english well enough that you can understand him, his command of the english language is weak enough that it makes it difficult for him to convey meaning and understanding from his classroom sessions. The icing on this rotten cake is the pace the professor must keep to meet the core requirements that are necessary for the class; you have no time to toil over theorems or proofs that you do not fully comprehend.

We recently just had our midterm. How quickly time flies. Unfortunately, even after hours of studying, I feel that I probably came out of that exam with either a grade of a ‘C’ or ‘D’. If the professor does not curve the grades, its quite possible that I may not succeed in my “Discrete Mathematics” course. From my understanding I think I may have a second chance in retaking the course and passing it to stay in the program.

If I do manage to pass this class, I made a promise to myself that I will never take another course during the winter or summer sessions.

I look forward to taking the programming based courses.
