Git
My first try of committing a project to bitbucket using git, went smooth enough. I think i will use this more for personal projects and may put my thesis project up on a github public repo after i clean up the code a bit.

Working with Libgdx
The Libgdx documentation itself seems to be a bit sparse in places as the developers seem to be far more focused on fixing bugs and rapidly developing new features.

Metasploit
Just tried out Metasploit for the first time, using its 7 day trial. Have to say it really does wrap everything into neat and pretty reports.

Expression detection using neural networks in OpenCv
The expression classifiers work well for discerning between when a person is smiling and not smiling.For other emotions they perform relatively poorly. I believe this is due to a lack of data, its much harder to find images of people with facial expressions other than smiling.
For discerning between smiling with teeth baring and an angry expression with teeth baring it performs surprisingly well, compared with how poorly it performs for discerning between fear , surprise and disgust. Perhaps its because these overlap?
All of the networks are using the pixel values of the images as inputs, face images are being scaled to 50x50 images which gives all the classifiers input sizes of 2500, hidden layers are between 9 and 12 neurons in size, and the output layer consists of 2 neurons one for a true value and one for a false value.

Smile detection using neural networks in opencv
Seems to work decently, occasionally depending on the pose it gets things wrong

Expression Detection
Seems to partially work, i believe i need more data for training the classifier and more inputs.
This was wrong, it was a completely fluke this worked at all as i had used far to many nodes in the hidden layer

Semi-Complete Network Trainer for my FYP
GTK Gui i have built for getting images and setting up and training classifiers using the Neural Network
functions built into OpenCV's Machine Learning library.
functions built into OpenCV's Machine Learning library.
It needs to be more adequately labelled, i think.
I also had some trouble with GTK spinner boxes which required repeatedly recasting the objects as (GTKSpinnerButton *) to (GTKWidget *) just to get them functioning together.
Complete pre-christmas games project
The Final Version of the Physics project done for my Game Engines one assignment, a partial success as i passed and got most features working e.g. rotating thrusters.
However the camera does not follow the "VTOL" well. And the aircraft is completely useless ,unless you consider tumbling into the sky in particular direction a decent way to get from place to place.
