For those who couldn’t attend Wikimania, the annual international Wikimedia conference, this panel of top contributors to the wiki community reviews some of the latest developments, lessons learned, and what to expect from Wikimedia in the future.
Adina Levin of SocialText leads a panel that includes Wikimedia executives and other noted wiki experts as they share highlights from Wikimania 2009. The panelists discuss a project that would allow Wikimedia to be more usable for contributers, opportunities to help Wikimedia move forward, and the latest wiki trends.
Yahoo!'s Micah Alpern describes the culture of Wikimania. Sue Gardner, Wikimedia's executive director, covers the foundations priorities and projects. Ed Chi of PARC summarizes his much-discussed research on the slowing growth of Wikipedia, with data, models, and possible explanations. Naoko Komura shows off the achievements of Wikimedia's Usability Project and describes its future plans. Jack Herrick of wikiHow describes his company's efforts to increase contributions to wikis.
The broad wiki community is strong, productive, and inventive, and our panelists are a few of the people who help make it a success. Whether you use wikis for reference, contribute to wikis at work, use other kinds of user-contributed media, or participate in open-source communities, you'll learn a lot from these experts.

Avoiding the Digital Death Spiral: Surviving & Thriving through understanding...Simon Tanner
Simon will consider how we can use a deeper understanding of value and impact to survive in an ever more competitive and confusing digital landscape. How do the cultural, heritage or creative sectors cope with the twin challenges of meeting the public desire for digital content whilst maintaining their curatorial responsibilities within what could be considered an unfunded mandate? Simon will investigate the values and benefits of digital with a consideration of the risks we face in what he refers to as the Digital Death Spiral. Simon will propose one solution in particular, The Balanced Value Impact Model (BVI Model) that he has recently developed. The BVI Model draws evidence from a wide range of sources to provide a compelling account of the means of measuring the impact of digital resources and using evidence to advocate how change benefits people. Simon will argue that putting people at the centre of our strategic thinking is both the most challenging and satisfying action we can take in securing our digital futures.

The Importance of Facial Features, Gretchen Anderson at BayCHIBayCHI
What's the key facial feature of your design? That one element that grabs people on an irrational level, reflects the big concept, and becomes the icon for your product or service. Gretchen Anderson points to BMW cars' split grill, Tivo's big, bright "pause" button, and the Flip camera's flip-out USB plug as examples of successful facial features. Yes, strive for usability, but the most usable designs can be boring. Your design needs personality, too!

Mindset for Achievement: How to Boost Achievement and Fulfillment Through Min...BayCHI
Carol Dweck at BayCHI, May 11, 2010: Mindset is a simple idea discovered by world-renowned Stanford University psychologist Carol Dweck in decades of research on achievement and success—a simple idea that makes all the difference. In a fixed mindset, people believe their basic qualities, like their intelligence or talent, are simply fixed traits. They spend their time documenting their intelligence or talent instead of developing them. Dweck's research also shows that praising intelligence can harm motivation by creating a fixed mindset. People also tend to believe that talent alone creates success—without effort. They're wrong. In a growth mindset, people believe that their most basic abilities can be developed through dedication and hard work—brains and talent are just the starting point. This view creates a love of learning and a resilience that is essential for great accomplishment. Virtually all great people have had these qualities. Teaching a growth mindset creates motivation and productivity in the worlds of business, education, and sports.
Designing Social Interfaces: 5 Principles, 5 Practices, 5 Anti-PatternsBayCHI
Christian Crumlish at BayCHI April 13, 2010: Designing for social interaction is hard. People are unpredictable, consistency is a mixed blessing, and co-creation with your users requires a dizzying flirtation with loss of control. Christian will present the dos and don'ts of social web design using a sampling of interaction patterns, design principles and best practices to help you improve the design of your digital social environments.
Elaine Wherry, Meebo: What Web Application Design Can Learn from the HarpsichordBayCHI
Baroque harpsichordists excelled at taking simple melodies and creating elaborate, beautiful pieces of music. But in their desire to push the boundaries of experimentation, these keyboard virtuosi eventually ornamented the music beyond the limits of good taste, making the composer's original melody unrecognizable. Listen to enough Baroque music, and you'll ultimately decide, "This is ridiculous. I never want to hear another harpsichord!"
Something similar happens in Web design. With new technology comes a natural desire to experiment, challenging fundamental design rules to push the limits of web applications. As designers explore just how far they can go, there inevitably comes a breaking point, where you think, "This is ridiculous. I never want to see another rounded corner!"
In both cases, the lesson learned is that just because you can, doesn't mean you should.
Web application interaction design brings a wealth of creative freedom and makes it increasingly important to identify the functional rationale for UI choices rather than gut reactions like "this is the way users are accustomed to it" or "this just looks better." Elaine will discuss how to approach web application design when, instead of one dominant voice, there's a multitude of web product and design philosophies.
Elaine Wherry is co-founder and VP of Products at Meebo. Originally a classically-trained violinist, Elaine graduated from Stanford University with a degree in Symbolic Systems with a concentration in Human-Computer Interaction. After graduating, she became the manager of Usability and Design at Synaptics. She co-founded Meebo.com in 2005 with two good friends, Seth Sternberg and Sandy Jen. Initially, she wrote Meebo's JavaScript framework and went on to build and oversee Meebo's web, user experience, and product management teams. Today, Meebo has approximately 40 million unique users in the United States and nearly 100 million unique users worldwide, according to Quantcast.
Scott MacKenzie at BayCHI: Evaluating Eye Tracking Systems for Computer Data ...BayCHI
The human eye, with the assistance of an eye tracking apparatus, may serve as an input controller to a computer system. Much like point-select operations with a mouse, the eye can "look-select", and thereby activate items such as buttons, icons, links, or text. Evaluating the eye working in concert with an eye tracking system requires a methodology that uniquely addresses the characteristics of both the eye and the eye tracking apparatus. Among the interactions considered are eye typing and mouse emulation. Eye typing involves using the eye to interact with an on-screen keyboard to generate text messages. Mouse emulation involves using the eye for conventional point-select operations in a graphical user interface. In this case, the methodologies for evaluating pointing devices (e.g., Fitts' law and ISO 9241-9) are applicable but must be tailored to the unique characteristics of the eye, such as saccadic movement. This presentation surveys and reviews these and other issues in evaluating eye-tracking systems for computer input.
Scott MacKenzie is associate professor of Computer Science and Engineering at York University, Toronto, Canada. His research is in human-computer interaction with an emphasis on human performance measurement and modeling, experimental methods and evaluation, interaction devices and techniques, alphanumeric entry, language modeling, and mobile computing. He has more than 100 peer-reviewed publications in the field of Human-Computer Interaction, including more than 30 from the ACM's annual SIGCHI conference. He has given numerous invited talks over the past 20 years.
Juliette Melton at BayCHI: Real World Remote ResearchBayCHI
Remote research can raise the quality and lower the costs of your user research efforts; using a combination of surveys, video, screensharing, and phone, you can connect with a much broader range of users than you could using traditional lab-based usability tests, while using resources more efficiently than you would doing contextual research. In this workshop-style talk, Juliette Melton will cover recruiting sources, technology tools, and caveats you might not have thought of, including managing time zones and participant distraction. We will also address pros and cons of increasingly popular non-scripted research services.

http://www.baychi.org/calendar/20100112/#2
Technology users are technology observers as well, monitoring for problems or opportunities that might arise. Designing interfaces to support the monitoring of technology presents unique challenges, like detecting situations and knowing how and when to respond, coping with a changing operating environment, and the changing knowledge of the observer.
Conrad describes "Heed," a scale and framework to help observers of a system evaluate which situations need scrutiny and when. He gives an example heed-based interface that encourages the development of situation awareness. Learn how the framework and interface can be applied in three different scenarios: server performance, a business's finances, and user experience in a community forum.

Joy Mountford at BayCHI: Visualizations of Our Collective LivesBayCHI
The lines between art, design, and information are dissolving as we experience new places and objects. Consider, for example, the organic flow of air traffic over North America at daybreak, the bursts of search query memes spreading around the globe, and the pointillist surge of mobile phone usage on New Year's Eve. Using the new techniques of generative data visualization, a new generation of artist/designers/engineer/scientists are creating gorgeous, dynamic experiences driven by massive sets of data about our own lives. Their work comes to life in architectural spaces, on walls of wood and metal and light and shimmering glass clouds suspended overhead. Of course it must be touched to be appreciated and engaged with, simple gestures launch a thousand images and possibilities. Many of these projects have received international recognition. They are primarily 3D applications that can run in real time, but really can only be appreciated by watching them, as movies. These data movies aim to make information easier to understand while being enjoyable to watch. Surprising insights surface through looking at our 'data life' in new ways, and may compel us to design in different, even better ways.
Taming Complexity and Sparking Innovation Through Ideation and Design ThinkingBayCHI
Gayle Curtis, Design Consultant at BayCHI, December 8, 2009: A design thinking approach to product development gives us a place to start and a way to proceed with problems that are tricky and ill-defined. It can help tame their complexity and uncover innovative solutions. At the heart of this approach is ideation, the capacity for generating ideas and entertaining alternatives, which we most often practice in brainstorming sessions. In this talk we will look at the background, values and techniques of brainstorming and how to structure effective brainstorm sessions. We will also look at the ways group brainstorms can enhance team performance and serve as the sparkplug for an innovation pipeline.
Aiming for Innovation: Living Design in a Business WorldBayCHI

"Well, we did all this research ... now what?"BayCHI
Steve Portigal at BayCHI, June 9, 2009: One of the most persistent factors limiting the impact of user research in business is that research projects often stop with a cataloging findings and implications rather than generating opportunities that directly enable the findings. As designers increasingly become involved in using contextual research to inform their design work, they may find themselves holding onto a trove of raw data but with little awareness of how to turn it into design.
Steve introduces a framework for synthesizing raw data into insights, and then creatively using those insights to develop a range of business concepts.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
