CS115/MAS115: Computing for The Socio-Techno Web Welcome to CS115 also listed as MAS115. image source: http://www.igenii.com/blog/Social%20Media/social-media/ twitter.com http://www.worthofweb.com/blog/case-study-this-revolution-will-be-tweeted/ http://foxwoodonlinemarketing.typepad.com/my-blog/social-media/ CS115/MAS115: Computing for The Socio-Techno Web What’s it all about?

Introductions Course staff: Catherine Delcourt (instructor) Takis Metaxas (instructor) Stella Kakavouli (lab instructor) Christina Pollalis (lab instructor) Han Qiao (Tutor) Lizao Wang (Tutor) We have a great team this semester – I’ll ask them to introduce themselves. I’ll be teaching lectures, I am also co-directing the MAS program – feel free to talk to me if you have any question. My research is in the field of Human-Computer Interaction, and in particular studying and inventing new ways for people to interaction with large data sets. In my research I am using new technology including large interactive surfaces. VR, AR, and more. This room is also my research lab – so during the semester my goal is to expose you to some of the HCI research that we are doing here together with students. There are 4 researchers working in the lab: (introduce them).

What is this class about? The technologies that have made the Web possible HTML, CSS, JavaScript The social Web Your experience so far? Technology as communication facilitator How familiar are you with communication technology? The past of our communication What changes when we change how we communicate? What questions do you want answered? This course is about computing for the socio-techno web. Technical base-line for understanding the web – technologies that makes web possible, get hands-on experience creating content for the web, programming using HTML, CSS, JavaScript. We will discuss the Social web - how websites and software are designed and developed in order to support and foster social interaction.[2]:These online social interactions form the basis of much online activity including online shopping,[3] education, gaming and social networking websites. We will put your experiences in context. Present and past communication technologies. The history of the internet,

CS115 in one slide Here is the entire course in one slide – showing the different topics that we will explore. 2 parallel themes: technical lectures/ theoretical lectures about important topic. Hands-on learning in the lab.

Goals of the class To get you out of Techno-phobia and into Techno-power To empower you in your use of Web technologies To help you understand how and why the Social Web works To help you appreciate the changes that it brings to our lives and to society To be able understand and critically think about events related to communication technologies To excite you so that you may pursue it further in the future To satisfy the Math Modeling or MA&S requirement To have fun! From content consumer to producer – empower you to use the web to accomplish your goals Also to understand the changes that the Web brings to our society And to be able to think critically about events and news related to digital media. We also want you to have fun along the way!

Collaboration Introduce yourselves! Complete the introductory question Computing is a highly collaborative field. And our goal this semester is to create a community for learning. You will collaborate in different ways – lets start by introducing yourself. Here is overview on our collaboration policy, and it is followed by a more detailed explanation below:  Assignments: Rotating pairs of students  Project: Teams of 2-3 students  Exams: Absolutely no collaboration Introduce yourselves! Complete the introductory question

Computers What things come to your mind when you hear the word “computer”? A computing system can be studied as a mechanical system, a software system, a human system or a social system, by engineers, computer scientists, psychologists and sociologists respectively. Draw pyramid

The evolution of computers How have computers changed? What are the consequences of these changes? The evolution of computing implies a requirements hierarchy: If the hardware works, then software becomes the priority; if the software works, then user needs become important; and if user needs are fulfilled, then social requirements arise.

Digital Computing ENIAC 1946 In 1946 the ENIAC - the first large-scale, digital general purpose computer is unveiled. It was the first digital computer that could be reprogrammed to solve a full range of computing problems. It was installed at the Moore School of Electrical Engineering, University of Pennsylvania. ENIAC was massive compared to modern PC standards. It weighed 30 short tons (27 t), was roughly 8.5 feet (2.6 m) by 3 feet (0.9 m) by 80 feet (26 m). ENIAC 1946

Personal Computing The Star is the first commercial personal computer. It was designed for “business professionals” and was introduced in 1981. It was the first computer to present a comprehensive GUI and it used many ideas that we are all familiar with, which is based on the desktop metaphor, and includes a mouse. Despite these good ideas the Star was a commercial failure. It cost 15K, IBM had just announced a less expensive with additional functionality and open architecture. based upon many ideas in the Star, Apple introduced a –predecessor of Macintosh, – the Apple Lisa it was somewhat cheaper ($10,000) – but still commercial failure. The Apple macintosh used “Old ideas” but well done. It succeeded because: –aggressive pricing ($2500) –and correcting the mistakes of hte star and the Lisa. Ideas are now “mature”. The GUI, the desktop metaphor and many concepts stayed with us. The mouse and the keyboard as input, screen for display.
