We’re making the box here the router and VPN solution so as we dig into this, expect a great deal more detailed how-to guides

With todays mobile internet being the big thing it is, and not having my ADSL connected just yet, I’ve been borrowing my house mates 3G dongle.  This is a pre-pay service to get internet through the 3G towers.  What the interesting part is when your quota runs out.

Many airports and cafes will provide internet access using an open wireless access point.  While you can connect to these access points, you try and open up a web browser and navigate to a web site, but instead of getting your desired site, you get a page asking you to pay for a limited about of net access.

This generally works as there are a few steps your web browser takes before you can receive a web page.  Generally speaking -> Web browser asks OS to resolve address (google.com for instance) -> OS asks the name server to resolve address -> Nameserver will traverse and ask other nameservers till it gets the address you want -> browser then connects to that address, port 80 and asks for the requested web page… etc

These access points will intercept the traffic to the web host, and instead of returning the web page, will bring up the page asking you to pay money.. note:  You’ve already had outgoing traffic though to resolve that name.

This is where the fun parts come in.  You can have a domain, and delegate a subdomain to another nameserver

so, we can set up our own private server (or a VPS, someone like ramhost.us will do this for $3 a month) then delegate access to a subdomain to it by adding a record to our nameserver:

dnstunner.ourhost.com.    IN    IN    my.vpshost.com

We can then run a little app on this server (see http://www.dnstunnel.de/) and tunnel a TCP connection over DNS requests (although, a little buggy and slow).  Then, the magic begins.  You can tunnel to a HTTP proxy, a VPN over TCP (such as OpenVPN) among other services (such as POP or IMAP, whatever really.)

So, what’s this got to do with getting you free internet?  Well, pre-pay Optus uses the same techniques to direct you to a web page asking you to top up.

Little note:  If you had outbound access to ICMP (ping), similar methods can be used to get net this way

Dad had a set of keyed screws, and luckily enough, one of them could crack open the phone without any damage.  Under close inspection, the button that the headset pushes on to hang up and answer the phone is connected to a leaver that rests on a button on the motherboard (as pictured below.)  It took several hours of fiddling with the little springs and metal plates in the switch with the multimeter to figure out how it worked, then carefully trying to bend and place everything back into it’s rightful place (the spring had come out of it’s tracks in the fall.. I can’t believe how cheap the components used were in this phone.)  Good news now!  I have my phone back!

CSCI356 Assignment 2

Here (link removed, I’ll re-enable it when the assignment spec for this years students changes enough not to copy this) is my assignment 2.  Once again, I have as much as possible, tried to make a strong OO design with my assignment where it’s very easy to expand on the number of weapons and elements in the game.  BePu was used in this one for the physics.  The code is kept fairly neet and many of the game components can be taken out and used in your own personal projects.  Right key moves to next weapon, up and down change the gravity of the world.  Enjoy blowing up those crates

As you might have seen in my Previous posts demo reel, here you will find the code attached for my CSCI336 As

signment 5.  Looking at how a few of my other friends completed their assignments for this task, I enjoyed having a more modular approach to OpenGL.  For instance, while it is possible to do this task in one function, the idea was that I wrapped my OpenGL calls in appropriate classes.

Examples of this are a GL_LIGHT is abstracted by the light class, you create a light, give it a type, and don’t have to worry about it being GL_LIGHT0.. GL_LIGHT7 (although, you can only have 7 li

ghts in your scene with this method).  Textures are contained in Texture structs with the appropriate functions to load and unload them.

The code is not as ne

ar polished and as complete as I wanted it to be, but it ended up being complete enough to build my assignment upon and satisfy all the requirments.  Hope you enjoy

The game is designed to run and perform on the Microsoft XBox 360 gaming console. The details of the xbox 360 can be found either from the Microsoft website or the technical documentation (found on this site). Our game makes use of the BePu Physics libraries and XNA Framework.

Some interesting times developing this project.  First, we probably didn’t communicate the best, so I guessed she wanted 12 lights, one for each note, turns out she wanted 48 (as you can imagine, the power requirements just went up 4 fold.)  We then re-designed the circuit to run on 15V instead of 5V (cheaper power supplies.)  and it all ended up working well .  You won’t have any idea of how big a project this was, but I think it was well worth it .  (the final rigging took over 20 hours straight to rig up, why Jade and her dad couldn’t have just build the frame out of chicken wire or a conductive material I don’t know )
