A Beginner's Example

I know, I know... No posts in forever... I'm sorry and I really don't have any good excuses except that I've been lazy... but I'll try to be more consistent now.

If you are not a beginner, you certainly don't need to read the rest of this post. If you do continue please feel free to mock any stupid mistakes I may have made.

Anywho... I come from two wonderful parents who are both actually very into computers. Growing up we always had to have the latest and greatest in technology and I don't think we ever had less than 3 working computers and many different parts. My dad has always been into the security aspect of programs which has never been one of my interests. My mother actually was a programmer back in the day of COBOL and PASCAL, but since she's had kids she's been a stay at home mom and the programming languages and techniques are very, very different.

Recently she's wanting to get back into coding and asked me for some tips and advice on where to start. I suggested a book that I had used for my Java class and sent her a few examples I had quickly created that were simple. This is one of the examples I sent. It's simply a Dog class with a few variables and functions.

class Dog
{
//These are private member variables
//They can ONLY be accessed by the Dog 
   //classes functions
private String dogName;
private String dogSound;
private String breed;
 
   //This is what is called the Constructor
//This gets called when a new instance of 
   //the class is created
public Dog(String name, String noise)
{
dogName = name;
dogSound = noise;
}
public Dog(String name, String noise, String b)
{
dogName = name;
dogSound = noise;
breed = b;
}
 
   //This function is going to display the noise 
   //the dog makes when it barks
public void bark()
{
System.out.print(dogName + " says: " + dogSound);
      System.out.print(" " + dogSound + "!\n");
}
public String getBreed()
{
return breed;
}
}


The Dog Driver class just creates a couple of instances of the Dog class to demonstrate how to use it.

class DogDriver
{
public static void main (String args[])
{
//These to lines call the Constructor of the Dog 
      //class and create new instances of the Dog class
Dog chihuahua = new Dog("Joey", "Yip");
Dog germanShepard = new Dog("Max", "Woof");
Dog corgi = new Dog("Sam", "Moo", "Corgi");
Dog poodle = new Dog("Lulu", "Bark");

//These two lines call the bark function of the Dog 
      //class and make the Dogs bark
chihuahua.bark();
germanShepard.bark();
poodle.bark();
corgi.bark();

System.out.println(corgi.getBreed());
}
}


It's going to be an interesting experience trying to get her away from the linear concept and more comfortable with the object oriented approach, but I think it'll be a good way for me to brush up on my rusty techniques and a great review for me.

I'm still alive

I apologize for my lack of posts... I've been working with SharePoint and it's taking all my power not throw my computer...

Hopefully soon you'll be hearing more about some of my projects I'll be starting now that I've graduated.
Also I've discovered a humorous and attractive side of Mr. Gosling for us nerdy girls :)

Enyo Woes!!!

Since I've finished my senior project, (I know it's not necessary to state that every time, but I'm super excited its done) I've been able to work a little bit more in the Enyo framework with WebOS.

I've been working on a goal tracker program but I've run into some problems. I'm hoping some one will have an answer! I've posted on the Enyo forums to no avail!

This is a problem I'm having with all the pickers in this project. None of them are opening up where they should. They always open up in the left hand corner. I haven't changed any of the code for the date picker, I'll I do is create one and put it in component and it opens up in the wrong place! Here's the code:

{kind:"DatePicker", labelClass: "whitetxtColor", label: "Due Date", name: "addDate"}

I've been working on making my app look a lot nice with some css. I've been mostly successful minus this modal dialog for deleting goals. This first shot is just the normal standard css, the second is my attempt to change things. All I did was simply change the className and contentClassName properties and it does change them... just not the entire ModalDialog. Any tips on how to fix this problem? Here's the code:

{kind: "ModalDialog", name: "deletePopup", className: "bkdark", contentClassName: "bkdark", components: [     
   {kind: "VFlexBox", flex: 1, components:[  
      {content: "", name: "confirmDel"},   
         {kind: "HFlexBox", components: [ 
            {kind: "Button", flex: 1, caption: "Cancel", onclick: "cancelClick"},
            {kind: "Button", flex: 1, className: "enyo-button-negative", caption: "Delete", onclick: "confirmClick"}
 ]}]}]}

Project Finished

I just have to show off... :D

Yes, it's a QR code to my blog... but more importantly it works even when rotated.

And proof that it actually can do more than just that QR code, here's three different ones and they are a different version than the previous one.

Here's a link to the google code project. You can use whatever pictures... it's just very temperamental... you can only have a white background and the lighting has to be just so... but it works... mostly!

//END OF LINE

FINISHED!!!!!!

So it works! I've finished the programming part of my project! I was super excited to get it done!!!
I ended up using a library to take the bits of data and find the text/website that the QR code had stored in it.

It definitely still needs a lot of work before it will be really useful, but it should pass all the tests I need it to for this class!

Rotations Take 2

After finally sitting down and focusing on the math part, I was able to get my program to rotate my image by some angle of whatever I want!

I'm pretty excited because that means I'm that much closer to being done. I also implemented an edge detection algorithm, which was pretty fun, and I'll be using it in conjunction with my rotation function to figure out and correct the skew of the image.

//END OF LINE

It's all 1s and 0s

Luckily I've been getting back to working on this project... I sorta realized that it's due in a little over a month and I am bound and determined to have a life (besides doing this...).

Today I still skipped out on working on rotations... (once again not looking forward to the trig and matrix multiplication I'll probably have to be doing) but I did get something else accomplished.  Once I have the QR Code pulled out, I can determine the bits of information from that image.

So there's the original image, the pulled out and rotated QR Code and then the data array of all the bits of info! Unfortunately it only works on pretty straight, non-skewed images... I'll eventually get it there though.

All I have left to do is determine what the bits have been encoded to, finish the rotation stuff, and possible port this to an Android phone... (the last part is still to be determined... I may not have the time to get that done and will have to resort to something else....)
