You can embed them anywhere just like youtube videos

I created a prototype for a simple GUI engine. The code will look something like this:
#include Engine.h //name TBD
int main()
{
//make your render object this, will be red
Surface mySurf(100,100,color(c_red));
//make your window named "HelloWorld"
Window myWin(200,200,"HelloWorld");
//my surface will be drawn once at the origin and once at the center
myWin << mySurf << mySurf.loc(100,100) << "\n";
//"\n" or '\n' or sync will dump the window to the screen
//wait 2 secs so you can see things
wait(2000);
//THAT'S IT!
}
//also, I need a new syntax highligher... =X
int main()
{
//make your render object this, will be red
Surface mySurf(100,100,color(c_red));
//make your window named "HelloWorld"
Window myWin(200,200,"HelloWorld");
//my surface will be drawn once at the origin and once at the center
myWin << mySurf << mySurf.loc(100,100) << "\n";
//"\n" or '\n' or sync will dump the window to the screen
//wait 2 secs so you can see things
wait(2000);
//THAT'S IT!
}

I was bored so I decided to make a much needed update to my blog
WHAT THE HELL!? WHERE DID RYAN GO!?
I'm sorry, it's been a LONG while since I've posted here. I'd say I've been busy, but that's only half the story. The other half is lazy. I probably COULD have made a post, but I haven't worked on many hobby projects anyway, so what would I have posted about? Anyway, I've started a new hobby project that is also favorite distraction: gaming.
But before we get into that, an update on my life.
I have started to work on a simple graphics engine. It was designed as a UI for the Sudoku solver I made, but it was more modular than that. I made this UI tool over a weekend for Sudoku Solver, but I have since used it in 4 homework assignments. It's based on SDL and it's highly portable (tested on Linux and Windows). I will pick it up when I'm done with my internship. I hope to make a UI builder that looks to the programmer like iostream. This will make writing UIs very easy for starting programmers (and make creating prototype UIs as easy as prototype command line apps).
I'm in an internship at Sabre. I've learned a lot here and further developed my skills as a Linux developer. I've also picked up some Java (I'm arguably already better than some of my intern peers that have spent years in Java, but lets just say they where too close to the code to see the problem and move on). Virtually my entire time here at Sabre has been parsing and graphing data coming from a major server cluster within Sabre. I've found this project extremely interesting and rewarding on a learning experience level and now that I've got most of it figured out, I would like to commit some of my fixes back to the open source tools I've used (baring that, I'll remake those fixes at home on my own time, don't know the legal implications of ether idea). I've enjoyed the project so much that I'm creating parsers for Minecraft logs put on MineTexas (formally Minecraft, TX) that will let us understand our users better.
And now the big thing. Linux Gaming. I made a commitment in recant past that I would shift my default boot OS on my main tower to Linux when Dota2 (my biggest excuse for not updating this blog) is ported over. That happened; now I plan to follow up on my commitment. I'm thinking about starting a blog as "cheap gamer" or "freeware gamer". I think I'll go into detail on what this means in a separate blog post since many people interested in details might not want to read all of that stuff above.

to do list
I've written a bit of hobby code this semester, but I haven't posted any of it. I'm posting this to make me go do it. I also plan on setting up a git server started, so I don't have to use other file servers.
If you know me, remind mute to get that code up here.

School is starting
School is starting now and my summer is over. I'm very disappointed in myself that I didn't get more coding done, however, I've learned a bit about SDL and my Sudoku solver blows my dad's out of the water (it can even solve some puzzles that his cannot).
This semester, I'm taking Game Programming 1 and Game Physics. For both of those classes, I might be writing relevant code, so I might post some assignments I found interesting.
I would like to write a UI for my Sudoku solver, but we'll see. I'm trying to spend my spare time working relevant stuff like this (instead of just using my laptop for gaming), however I've got a lot of homework too, so we'll see about that too.

I was bored because I couldn't figure out this thing...
Building a (week) game engine using SDL, will probably convert it to OpenGL eventually, but until then, THIS:
Now, I like to think of my self as pretty fluent in C++ syntax, but for the life of me I can't figure out what the heck I'm doing wrong. This isn't the code I'm actually working, but it has the same syntax problem as what I'm actually doing. I have a class that acts one way, then another one the is almost exactly the same, but it has a compleatly differnt constructor and a few extra functions attached to it. So, I was going just inharit off of it overloading the constructor, but it doesn't seem to be working... clearly I'm doing something wrong...
#include <iostream>
class Number
{
private:
float x;
public:
Number( float input)
{
x = input;
}
}
class OtherNumber : public Number
{
private:
public:
OtherNumber( float input )
{
x = 0;
x -= input;
}
}
int main()
{
}

I was bored, so I wrote a Sudoku Solver
My Dad wrote a Sudoku solver that works in Excel . It's slow. I was discussing with him how he built it and I starting thinking how I would build one.
So I did. And it's messy. But it works!
It's messy, it's not a release, and the comments suck... but it works! (now, someone give me a puzzle that breaks it!
ToDo:
1: Better Input System
2: Better Debug Logging
3: Suggestions?
