Quantum Physics in 1990s programming.

Just to prove his point on how an A press is divided into two halves, this guy mainuplates the programming of an age old game to prove the existence of parrell universes, QPUs, hyperspeed walking and much more mind-boggling stuff. I'm not kidding!

By the end of this 20-minute demonstration your mind will be blown.

Awesome Infographic!

John's Choices

John's Choices

For my project, I'll be using a timeline to represent the change over time as well as a column chart and a pie chart to display,

The data I collected is from the United Nations Data website and data.worldbank.org

I will be researching the use of mobile phones in various different country's to see whether or not the phone manufacturing country's are prone to more mobile usage than country's that are consumers of the product's produced.

Rahul - Data Visualisation Post 1

For my visualization, I plan to use a pie chart to show how employment affects internet usage over between the years 2006 and 2011. I also plan to use a bubble chart to display the change in internet usage over time vs. the number of people employed and the population of the country.

Weeks 8 & 9 - Presentations & Topic Test for U2O2

Your Presentations are due on Friday 2 September!

For maximum opportunity for feedback on your work please follow the following guide:

• Complete your visualisation by TUESDAY 30 September
• Thursday 1 September you will prepare your presentation
• Friday 2 September: You will present to the class.

REMEMBER!

8.5 Computer Lab is open on monday, Tuesday and Friday lunchtimes for students to work quietly on IT related projects. Make the most of this opportunity!

TOPIC TEST - Friday 9 September!

Bunmi's Choices

The data I collected was from investigations conducted from 2012-2013 and is represented as percentages within a Margin of error, as the Census was not conducted by the ABS on 2012 or 2013 I had to take an estimated population for both years from the ABS

For my project, I decided it would be best to present my data through pie and line charts to show proportions and identify relationships, also I will use area charts to compare two data sets at once and bubble charts to show a combination of the variables on one plane.

From the links I've explored on the blog, I've decided that  to make my visualizations simpler and more interactive it would be beneficial to allow the user transition from chart type to the next instead of dumping and compressing them into one space. Additionally, I'll be making use of a limited colour palette and present my visualizations in a minimalist style so that it is easy to read

Response Jackson Cook

Response Jackson Cook

For my practical I am going to be using both gauge diagram and a timeline to display my data, as the gauge allows me to thematically display my data comparatively and the timeline allows me to display the data over time.

In investigating possible visualization examples, I found that by using scale in my data allows the viewer to have an insight into what the data actually means rather than them just being displayed numbers and statistics. I also found that by having an aspect of interactivity can be used to entice the viewer and make the presentation more interesting rather than using static diagrams.

Barry Jones' Knowledge Nation

Barry Jones was the Minister for Science and Technology and he presented this diagram to launch thr program "Knowledge Nation"

But due to the complex nature of the diagram he was ridiculed despite the fact that the program was an important development fo rthe country. The link below is an SMH article reflecting on the bad press as a result.

http://www.smh.com.au/articles/2003/11/24/1069522520166.html

The CORRECT notes.

In relation to programming, there are several different data types which include:

• Text(String)
• Integer
• Floating point (real) numbers/ i.e Single or Double
• Date/Time (Timestamp)
• Boolean
• Character
• Byte
• Currency
• Etc.

It is important to consider the structure of your data when choosing a data type as pieces could be lost in the exchange or the information may become unusable/invalid.

For instance, converting a time-stamp into an integer means that numbers after the ':' (i.e minutes/seconds) will be erased in favor of the hours.



When storing text, sound or images, it is important to consider it's resolution which is a measure of how much detail is in:

• Images (dots per inch when printed or pixels per inch when onscreen and colour depth)
• Videos(frames per second, frame size and bitrate)
• Audio(sample rate of frequency, bit depth and number of channels)

This is especially of concern when considering methods of compression, Lossy methods of compression are designed to shrink file sizes but result in a loss of detail.

On the other hand Lossless compression can not reduce file sizes as much as Lossy methods but they do not reduce the quality of the file instead they summarise the data.

Digital systemsare comprised of the hardware and software required to support programming and software use.

They are divided into several groups:

• Networks exchange data between groups
• Rules/Protocols that coordinate and standardise communication between devices
• Software which is present in the form of systems, applications or utilities
• Hardware as physical equipment for input, output, storage, processing and communication
• Application architecture, which are principles that provide a framework for resolving recurring errors.

Hardware such as processing hardware and input/output devices are components of digital systems that we can physically interact with

Processing hardware such as CPU and GPU convert data into information while coordinaing all of the other hardware in the system.

There are a few different utitiles that are useful when building programs:

• Editors are text editors that allow a programmer to write or modify code
• Compilers converts programmer's code to machine code so it can be executed
• Linkers are Libraries/Collections of useful modules/small software that can be incorporated into the program
  
  In programming, functional requirements are things that the program is required to do and non-functional requirements detail the process of how the program meets the functional requirements. 

In order to carry out these functions, the program must receive compiled language that is converted from the interpreted language that the programmer reads, the programmer may also utilize internal documentation to explain the purpose of certain sections of code.

Internal documentation is an important part of programming along with structure diagrams such as IPO charts, Pseudocode and Object descriptions as they reduce the probability of Syntax and Logic errors from the programmer and invalid code, allowing programmers to focus more on debugging Runtime errors

Sumary Notes Jackson Cook

Summary Notes     Jackson Cook

CPU: Central Processing Unit – the ‘brain’ of the digital system, as it handles most of the systems data manipulation.

GPU: Graphic Processing Unit – very fast High speed processor designed for high speed graphics through graphics card.

 

Storage:

Primary storage: Primary storage is a computer Random Access Memory (RAM), this means it can only stores data and information whilst the power is on.

Secondary Storage: Stores data and information when they are not being used. It is most common for it being stored on the hard disk drive.

 

Operating System

Operating systems such as Macintosh, Windows and Linux is software that controls a computer’s hardware and runs the users application.

Software Development tool:

Essential tools including: Editor, Compiler, Linker, Debugger.

Editor: a specialised word processor that is used for creating human readable source code.

IDE Integrated Development Environment

Creates an environment for programmers to input code through, and potentially create interface for.

Example: Microsoft Visual Studio

 

Data Types:

Text: Alphabetical, characters, punctuation – any group of characters that can be typed.

Integers: Whole numbers, no fractions

Date/Time: used to perform complex time and date calculations

Boolean: True or False, checks whether data is checked or not.

 

Structure Diagrams:

IPO Chart: Used to design programs algorithms and formulas in its basic form of input, processing and Output

Object Description: OD is used for the naming and behaviour of objects used in code. E.g lblInput

Pseudocode: Fake code, used to organise the structure of the algorithm.

Interface Mockup: simple layout of interface to show how the data will be inputted and outputted.

Fundamental Programming Concepts

Compiled and Interpreted

Compiled: programming code that can only be read by computeR

Interpreted: Programming code that can be read by the programmer

 

Internal Documentation: Explanation of the functional and purpose of the source code

 

Debugging

Logic Error: Logic errors are made when the programmers structure is incorrect, making the program innoficiant.

Syntax Error: Syntax Errors are where the source code is invalid creating invalid instructions that the program can’t read.

Runtime Errors: Runtime Errors are caused by factors caused through the hardware.

Week 9 notes

Data and Information:

There are two basic types of data

Quantitative Data is measurable and specific and therefore easier to represent in  a visual format, It also tends to be numerical

Qualitative Data is generally allows for rich descriptions and represents the participant's feelings or opinions

Quantitative data tends to be less time consuming to collect than qualitative data, however the information that is collected is not in detailed as in Qualitative data due to its numerical natures.


Both types of data are usually collected through techniques such as:

• Questionnaires and Surveys
• Focus Groups
• Interviews
• and Observation

Consequently, they are visually represented through graphs such as Pie or Bar charts or Info-graphics.

Digital Systems:

Digital Systems are divided into three groups:

• Communication Devices
• Communication Software
• Internet Services

Communication devices such as routers allow communication and exchange of data, instructions and information between two devices,

Communication software (such as network operating systems) are programs or apps designed to pass or support the movement/exchange of information.

Internet services are programs or software that support the use of resources found on the internet, for example, internet browsers enable users to view webpages and cloud storage provide a backup location for data that can be accessed by multiple devices.

Approaches to problem solving:

It is often unsuitable to report on data using its raw form so there are various graphic solution used to visually represent data such as:

• Charts
• Flowcharts
• Images
• Hierarchies
• Animations
• Maps
• Infographics
• Etc.

However there are several conventions for graphic solutions that must be followed:

The solution must be functional, which means it is useable across many mediums and easily accessible and it's appearance must follow conventions related to alignment, repetition, contrast and 

space

Additionally it must have a clear title, appropriate font, shapes,lines and arrows that divide sections of information as well as colours and contrasting brightness that make the solution pleasant to the eyes/

It is equally as important to include the source of your data as well as a legend so that clients can easily interpret the data and be assured of it's credibility.

Robustness VS Tolerance

Tolerance is the capacity of software to forgive user errors, such as when they accidentally click on a link or make other typical errors. A tolerant interface will allow the user to cancel, go back, or undo an action.

Robustness is the capacity of a system to cope with stressful or unusual runtime environmental problems, such as running low on memory or disk space, equipment faults (e.g. printer not found), dumb/invalid/unexpected user inputs, high usage levels, and uncommon but feasible events that would break lesser software - for example, coping with a user whose street address is just "11 Broadway" with no "Rd", "St" or "Av" field.

Usability

Check out this site that presents the elements of good web design and interface design:
http://www.usability.gov/tags/user-interface-design/index.html

Design Choices

Our website has working links that lead to every page no matter where the user is, it will also be able to sense the type of device that the is be used to view the website and scale and move elements of the page to better suit specific devices.

Smartphones users will be able to navigate through pages by tapping the links in the menu, we will also include links to the the sub-topics within the relevant pages. Each link is labelled in a way that clearly describes the contents of the page.

We have decided not to use symbolic icons in place of text to reinforce the simplicity of our website, as such, we have made sure that each page is identical in colour and structure to ensure that users are not confused.

The only information contained in the website are facts and research that inform users of our reliance on technology and relevant issues.Following the 'F' writing convention ensures that users will not have trouble finding our information or where they should start reading.

Our limited colour palette and font gives our website a sense of professionalism and makes users more likely to consider our information rather than ignore it. The use of white space ensures that the contents of each page is not cluttered and illegible.

We decided on a landscape orientation as a portrait page would stretch the information down the page, making users have to scroll down for long periods of time. We made sure that the content on the homepage was minimal or brief in comparison to the available space on the page to ensure that we could add extra content or media later on to catch the user's eye.

~Bunmi, Rahaul, Jackson

Salting

Check out this link and find out more about "Salting":
http://www.msn.com/en-au/money/company-news/millions-of-linkedin-ids-for-sale/ar-BBtcVl9

Short Report

We decided to include the research we conducted as well as some our primary data to better inform users about technology reliance and illustrate the presence of technology in our lives. Some of the primary and secondary data was removed as it was descriptive rather than informative.  For example, we did not include what the survey participants primarily used technology for.

We’ve arranged the menu by topic and utilized simple drop down sub-menus to make it easier for users to choose whether they want to learn about a specific part of technology reliance or it’s issues, such as the stakeholders in technology reliance or the impacts of our reliance on technology and navigate back to the homepage swiftly at anytime.

Our website has an about us page which will have contact details so that users can email any questions or suggestions they might have to us, which will provide room for more information to be included and enables us to identify when to update our website if it turns out the data is inaccurate or outdated.

Due to the fact that the information takes up small portions of the screen, additional information can be added without the need to scroll down for long periods of time. In the event that we have an excess of information on one page, it can be broken down into separate topics on the menu bar or the fill down sub menus as additional pages.

Chapter 4# Q's

CHAPTER 4# Questions

Information systems in action

Q2)List the four components of an information system: Data, Hardware, Networks, Software.

Q4)Explain what the term ‘digital system’ means:  Digital computer, a computer handling information represented by discrete values. Digital electronics, electronic circuits representing signals by discrete bands of analog levels, rather than by a continuous range.  

Q6)Identify a situation where downloading a file may be legal:  It would be legal to download Free and open source software. It is software that is released under licences that ensure that end users always have the freedom to run the program, for any purpose, the freedom to study how the program works, and adapt it to their needs, the freedom to redistribute copies of the program to others  

Q8)Explain how the concepts of copyright and intellectual property are related: Both are legal rights for a business/corp to apply use and distribution of its product.

Q10)Explain how peer-to-peer(P2P) file sharing works:  The file-transfer load is distributed between the computers exchanging files, but file searches and transfers from your computer to others can cause bottlenecks. 

Q12)Outline how artists may be disadvantaged by illegal downloading and streaming:  Illegal downloading of an artist's work, be it an author or a musician, deprives that artist of the residuals connect to the sale of his/her production.

Q14)Disscuss three ways that social media may become problematic for sportspeople: Foul language, Entertainment from trolling and morale issues arise.

Q16)Explain the purpose of a hashtag: A hashtag is a type of label or metadata tag used on social network and microblogging services which makes it easier for users to find messages with a specific theme or content. Users create and use hashtags by placing the hash character (or pound sign) # in front of a word or unspaced phrase, either in the main text of a message or at the end. Searching for that hashtag will then present each message that has been tagged with it.

Q18) Disscuss some of the negatives around the introduction of new technology in the agricultural sector: The current work force in the agriculture industry may have poor skill and require qualifications to operate newer technology. Being in an isolated position means it is harder to find the skilled workers.

Q20)Explain why e-commerce has become so popular: Shopping online makes it easy to browse a full selection of products easily without having to sort through all of the items commonly found in a brick and mortar store. eCommerce stores have made it seamless to find exactly what you are looking for and complete the transaction quickly and efficiently.

Q22)Explain what ‘Phishing’ means: Phishing is the attempt to acquire sensitive information such as usernames, passwords, and credit card details (and sometimes, indirectly, money), often for malicious reasons, by masquerading as a trustworthy entity in an electronic communication.

Q24)Discuss three precautions people can take to reduce their chances of both card and identity theft:  

• Clear your logins and passwords. This is especially important if you’ve been working on a public computer. Change logins and passwords monthly.

• Pay for online purchases with your credit card, which has better guarantees under federal law than your online payment services or your debit card.

• Be alert for phishing, a trick in which spam or pop-ups mimic legitimate banks or businesses to obtain your personal information, which they use to access your accounts. Always verify that you’re on a familiar Web site with security controls before entering personal data.

Q26)Outline two issues arising from the use of an Electronic Health Record(HER):

-There are chances of health records being sent to a wrong location.

-Network failure can delay access to any records.  

Expressing opinions

Q28)  Discuss why social media sites are a popular outlet to express opinions about information systems:

Q30) Describe the advantages of written comments over a rating system for opinions: Written comments give a more detailed and in-depth review of the ‘persons’ opinion, it also gives a better idea of what the person is think.  A rating system could mean anything, or poorly display the users full opinion.

Methods and techniques to acquire data and information

Q32) Explain the difference between primary and secondary data sources:  The difference between primary and second research collection is that primary research data collection involves conducting research oneself, or using the data for the purpose it was intended for. Secondary research data, on the other hand, was collected by a third party or for some other purpose.
