For this week’s post I decided to reference a B-list satirical science fiction movie called Iron Sky. The basic plot of the film is that during the final days of the Nazi regime during World War II, an elite group of Nazi soldiers and civilians was sent to the dark side of the moon to colonize the planet and wait for the rise of the 4th Reich (here is a more detailed synopsis of the plot for those who just can’t live without knowing ( http://www.imdb.com/title/tt1034314/?ref_=fn_al_tt_1).
There are some truths and myths in this film directly relating to the Moon. One of the biggest myths portrayed in the film is when the young school kids state that they live on the dark side of the Moon. We all now know after the second week of this course that there is no such thing as a truly dark side of the Moon. So in the film the idea that the people of Earth would not know they were there because they were hidden is completely incorrect. One fact they did get correct was that there are large quantities of Helium-3 on the moon. Some current day scientists have proposed the idea of mining Helium-3 from the Moon as a safe and clean energy source. In the film both the Nazi’s and the countries of Earth all discuss the importance of the Helium-3 on the Moon and want control of it.
For those who are in the mood for an easy movie watch this long weekend I suggest this film and encourage you to try spot all the things they got correct or completely wrong.

Hello class,
The Dark Side of the Moon was a classical album performed by the British rock band Pink Floyd. This work of art came out right around the time when the United States of America and The Former Soviet Union were in a competition to reach the moon first. The moon was so important to reach at that time because it symbolized the ability for mankind to achieve the unthinkable. However, the songs within the album generalized the moon for its superstitious powers and what it would do to people.This is why it is called the Dark Side of the Moon! The song "Brain Damage", depicts this image of insanity very cleverly in its final lyrics of the song. It states "And if your head explodes with dark forebodings too. Then i'll see you on the Dark Side of the Moon."
I do not mean to sound biased, because I am actually a black man and it is not typical that you hear someone out of the majority of Caucasian species revere music like there's, but it is actually really good music. I believe it makes you think about how far we as a people have come and what we are capable of when we put our minds to it. Psychedelic.

Hello all,
When working with the UML models I chose to illustrate the Doctors class and the interactions that goes with that class. In theory this class has many different operations (no pun intended) that it can have and subsequently many different types of states it can be in. Because it is the primary class many of the other classes like Lab results/messaging are weak entities and wouldn't be there if it wasn't for the interactions between the Doctor & user. The doctor class I feel had to be simplified to get the point across which I completely agree with but I do feel that this application is quite complex because of many of its transition's that I can potentially have. I chose to simplify the UML because in order to keep it simple I only had several state variables i,e.
public class Doctor(){
$Meds;
$Messaging;
$Results;
}
These obviously aren't everything the real world doctor class would take on probably 15 different state variables to account for all the different interactions it has on a daily basis.
What I found the hardest was actually the technical side of the house. Figuring out the CASE tooling system took me quite a bit and I am still learning how to use it in a better way. I am also quite excited to be able to make such great UML's/ERD's with it so this has propelled me to get better at it. What is great about this program is that this is something that I will be able to intergrate into my own coding standards.
Cheers

Greetings fellow classmates,
So attached is my UML Case Diagram. This was my first time using this program. Actually this was my first time trying to create a case diagram. It was a bit of a challenge for me. I am fairly certain that I missed some crucial pieces. So let me apologize in advance for that. But I have two actors, the Patient and the Doctor. In the system itself, I have the use cases; Makes Appt, Orders Refills, View Lab Reports, and Updates Files. I ran into problems trying to make the connections. I was a bit confused. Since this was my first time using this particular program, and my general level of familiarity of the concept, I found the program a bit challenging to use. I think that if I had a better grasp of the subject, this program would have been a huge help for me. As it is right now, I am not comfortable using this program. Hopefully by the end of this course I can become more proficient. I would appreciate any feedback you guys might be willing to give. Thank you!
Respectfully,
Chris

We learned about the relationship between activity diagrams and case descriptions. We know from previous chapters that activity diagrams “Describe user (or system) activities, the person who does each activity and the sequential flow of these activities (Satzinger) and detailed use case descriptions are simply detailed examples of user triggered business event so while the detailed use case explains what is happening the activity diagram is mapping out the process the use case will use to get from start to finish.
In the System Sequence Diagram (SSD) the SSD describes explicitly how the information is routed as it enters and exits the system. And the activity diagram interacts much like it does for a use case maps out the process or identifies the flow of the process. For example if I go to an online retailer and want to buy a Hard drive. There may be a product description link The SSD maps out what happens when I click the product info link and the activity diagram maps out the flow of information that makes it happen.
We have also learned that status conditions of objects can be referred to as states. An example would be if you order a product on line and you track the progress as it is shipped to your house. It can go from a “purchased” state to a “processed” state to a “shipped” state and finally to a “delivered state” The space between the states can be called a transition, all these states and their sequence can be represented in a state machine diagram. Over all we have learned that the detailed use cases help create activity diagrams such as SSD’s which helps model use cases and state diagrams can help model the domain

Hello all,
This week we are discussing several things. Activity diagrams are by definition all the various actions that one takes in order to fulfill the use description. The case descriptions gives us a defined path of things to accomplish and the activity diagram illustrates that. We also know about System sequence diagram. Let me first start by stating systems are event driven, the so called reactive system. With that being said SSD is used to describe behavior and there lies the overlap between the AD & SSD. What SSD's are most prominent for is showing the I/O of a system and thus showing the functionality of the said system. From what I have read and understand is that each of these are great tools to show the life-cycle and showing transitions of the given system. State machines do just this best. State machines can be broken up into two different categories, behavioral state machine and protocol state machine. Behavioral state machine does what is says it describes best the system in how the data will interact with the system, if anybody has taken Discrete math, its an iteration of nodes that cross from one part of the tree to another. This is the best way I know of describing it. Protocol state machine, this gives us the types of specific protocols in which the system is dependent on. Much of its behavior is relational in as much as it depends on the crud operations to discern its different types of protocols it will use.

The main role of CSS in HTML coding is to provide a more organized method of adjusting and editing your web page outside the main HTML files. The advantage to style sheets is that it provides one easy location to contain and edit the formatting instructions for the web page and consistency throughout your web pages. With CSS, you can define standard adjustments to your text, headings, footers, background, and lots more. For example, you can make horizontal lines using the horizontal rules. Syntax is you are editing and the structure is the way you write the Code in the CSS file, it works by identifying the selector, the opening curly brace, the property you with to edit, then the value of the new item, lastly closing curly brace. CSS helps managing layouts, positioning and appearance of the page, by allowing you to write one set of code to affect every page of your web site the same way. Incorporating multimedia with in the CSS sheet helps get basic setups and changes of images on all the HTML files quick and easy. The purpose of different styling techniques with CSS is to allow many versions of the same file and manipulate the code to work best with your web page.
--Missing Link--
I believe Omar’s link-checking software will keep the links valid for a little bit of time. This is because in the information changes on the site the software might not know what the original text side it will just know the site link is still active. It is important to occasionally check your hyperlinks manually because you can make sure the information stays relevant at the other end of the hyperlink. It is important to use both external and internal links to make it easier of users to move through your website and see other websites information.

Cascading Style Sheets (CSS) are extremely helpful when paired with HTML. An external styling sheet can be used to uniform make styling changes across a webpage, for instance: making the background color and font type, size and color all match across dozens of separate pages that comprise one web site. CSS functionality isn’t limited to just coloring changes or font sizes, it can also be utilized with formatting images and other media types. External CSS structure and syntax involves selectors (which area the coding will affect), opening and closing curly braces { }, defining which property to be adjusted (background-color, or font-size, etc.) and then the actual value itself, which is what you are setting that property to be, for example the color blue, or the font Arial, or font size 18 pixels and many more options.
CSS can be useful to manage layouts and positioning of headers, paragraphs and images as well, but most importantly, making them uniform for a cleaner looking webpage, one that is consistent in it’s coloring and spacing, allowing for a better user interface and user experience. One way that CSS allows management of positioning is by specifying margin amounts or floating orientations. As I mentioned, CSS can be utilized to incorporate media and manage common floating or setting of pixel width/height and orientation settings via properties such as ‘float’ or ‘margin’. Different styling techniques with CSS exist and provide web designers with a plethora of options to tailor web pages to desired functions and appearances.
Omar’s method of dealing with the dead-links is helpful but it won’t make his links on the site always valid. The automatic link checking software isn’t going to fix the links itself, but rather it would just generate a notification to the developer, who would still have to go and manually update each link. So the notification software will help keep the links on Omar’s site valid, by helping to notify the developer when they are dead, but until the developer takes action, the links will remain dead. Checking the hyperlinks manually from time to time would help validate that the automatic link-checking software is functioning as intended, rather than just relying on the idea that it’s functioning properly and foolproof (trust but verify). Utilizing both internal and external hyperlinks can allow for easier navigation of a web page from page to page, if there are multiple pages associated with one webpage. External hyperlinks are useful for linking to other websites that may be related to your web content or may need to be referenced.
