    This volume reveals the capacious albeit underappreciated communities that are making, playing, and studying queer games, demonstrating the centrality of LGBTQ issues to the gamer world and establishing an alternative lens for examining this increasingly important culture. Ekbia and Bonnie A. Through our clicks and swipes, logins and profiles, emails and posts, we are, more or less willingly, participating in digital activities that yield economic value to others but little or no return to us. Arguing that heteromation is a new logic of capital accumulation, Ekbia and Nardi consider different kinds of heteromated labor: communicative labor, seen in user-generated content on social media; cognitive labor, including microwork and self-service; creative labor, from gaming environments to literary productions; emotional labor, often hidden within paid jobs; and organizing labor, made up of collaborative groups such as citizen scientists. Ekbia and Nardi then offer a utopian vision: heteromation refigured to bring end users more fully into the prosperity of capitalism. The Stuff of Bits By Paul Dourish Virtual entities that populate our digital experience, like e-books, virtual worlds, and online stores, are backed by the large-scale physical infrastructures of server farms, fiber optic cables, power plants, and microwave links. But another domain of material constraints also shapes digital living: the digital representations sketched on whiteboards, encoded into software, stored in databases, loaded into computer memory, and transmitted on networks. These digital representations encode aspects of our everyday world and make them available for digital processing.

    This will be the first undergraduate degree offered by the School of Information since its founding in The School of Information already contains a Master's program, Doctorate program, and a professional master's program in conjunction with the School of Public Health.

    The BS in Information at the University of Michigan will be the first curriculum program of its kind in the United States, with the first graduating class to emerge in Students will be able to apply for this unique degree in for the Fall semester; the new degree will be a stem off of the most popular Social Computing track in the current Informatics interdisciplinary major in LSA.

    Applications will be open to upper-classmen, juniors and seniors, along with a variety of information classes available for first and second year students to gauge interest and value in the specific sector of study. The degree was approved by the University on June 11, Bachelor of Science in Informatics is described as "[a] program that focuses on computer systems from a user-centered perspective and studies the structure, behavior and interactions of natural and artificial systems that store, process and communicate information.

    Includes instruction in information sciences, human computer interaction, information system analysis and design, telecommunications structure and information architecture and management. It combines fields such as information science, computer science, statistics, design, and social science. The Informatics HCI option allows one to blend your technical skills and expertise with a broader perspective on how design and development work impacts users.

    Courses explore the design, construction, and evaluation of interactive technologies for use by individuals, groups, and organizations, and the social implications of these systems.

    This work encompasses user interfaces, accessibility concerns, new design techniques and methods for interactive systems and collaboration. Coursework also examines the values implicit in the design and development of technology.

    Information Architecture: Information architecture IA is a crucial component in the development of successful Web sites, software, intranets, and online communities. Architects structure the underlying information and its presentation in a logical and intuitive way so that people can put information to use. As an Informatics major with an IA option, one will master the skills needed to organize and label information for improved navigation and search.

    One will build frameworks to effectively collect, store and deliver information. One will also learn to design the databases and XML storehouses that drive complex and interactive websites, including the navigation, content layout, personalization, and transactional features of the site.

    It is crucial for organizations public and private, large and small. In the IAC option, one will be equipped with the knowledge to create, deploy, use, and manage systems that preserve individual and organizational privacy and security. After a course in the technical, policy, and management foundations of IAC, one may take electives at any campus to learn such specialties as information assurance policy, secure coding, or networking and systems administration.

    Finally, asynchronous or elastic circuits function far more dynamically, without a clock at all. I have already mentioned braking in corners. Temporal synchronization is just as crucial to large system simulators, built by coupling local simulators using their own simulation clocks.

    Logical time, physical time 41In another vein, we find that two notions of time often compete in daily life. These events can be seen to define a logical time, by their reproducible though irregular repetition in relation to physical time.

    Their physical precision is not necessarily great, as shown by the etymology of the nice French word tintamarre racket : the workers of Parisian vineyards were highly organized in former times, and demanded a real midday break.

    But this hour where the sun reaches its zenith in the sky is difficult to determine. When he could really feel it was time, the union leader would take a stone and chink tinter it against the iron of his hoe, called a marre. When all the other vintners did likewise, they produced a splendid tintamarre!

    This does not prevent us from working in logical time when designing the circuit, by acting as though time was regular.

    College of Computing & Informatics | Drexel CCI

    One of the seminars of the lecture series will present elastic circuits 16 , a wonderful way of coordinating flexibly logical and physical time. When programming embedded software, we also often use logical times that are finely correlated to physical time only at the implementation stage, or even during the system integration.

    Multiform time 44We can go further by calling logical time any quasi-time defined by the repetition of a given event, and discuss it with the same vocabulary and logic that we use for physical time. When walking towards a village, metres, and steps are just as often repeated as seconds.

    There is no difference between saying that the village is 10 minutes away or saying that it is 10 kilometres, 10, steps 10 kilosteps or 10, heartbeats 10 kilobeats away. Thus, all time logics together constitute a multiform time.

    The Esterel programming language, which I will briefly describe further on, was designed to program applications by playing on the idea of multiform time. It can be applied equally to real-time control applications and to the specification and synthesis of multi-clock circuits, for which each clock is seen to define its own logical time.

    Modern physics no longer necessarily sees it as continuous on the basic scales, nor even as something which should remain a primitive concept, which is of no concern to us here. More important is the fact that the notion of dating by using real numbers is not natural in informatics, as real numbers with an arbitrary infinity of decimals are not computable.

    We therefore also need discrete scales of time, founded on countable and computable sets of instants and discrete events.

    In order for our work to remain compatible with regular physics, we can carry on using real numbers to refer to discrete dates. This is what is called timestamping, which is particularly useful in telecommunications and database synchronization.

    But we can order events only partially, without necessarily defining a relation of precedence between two instants. In this case, precedence becomes a partial order.

    This is what is often done in asynchronous distributed systems, where actors do not share a common time and where the transmission of messages can take any time. Timestamping is then done in logical time. The thickness of the instant 47In everyday language, the notion of event has a very broad meaning, and is somewhat different from the mathematical notion of the instant without density. For example, we are taught that Charlemagne was crowned in This sentence of everyday language can and should be seen on several scales.

    Broadly speaking, the year is a moment in history, and Charlemagne was crowned at that moment. But the year was composed of days, themselves comprised of 24 hours, etc. Depending on needs, the same event can be seen as atomic, and therefore indecomposable, or rather as aggregated, then representing the abstraction of a succession of more basic events. We will juggle between these two visions of an event: in the atomic vision, we will consider that the aggregated event happens in zero time, which will be formidably efficient mathematically speaking.

    The Informatics of Time and Events

    The key to correcting this double mechanism will be precise control of the real temporal sequence, which will allow us to ensure that the abstraction of zero time is reasonable in practice for the domain considered. The question of determinism 49The difference between determinism and non-determinism is important for our systems. A system is deterministic if its reactions are always identical in identical situations, and non-deterministic otherwise.

    But, if the system must always react in the same way to the same inputs, it must not contain internal non-determinism.

    Conversely, it is important for the transmission of packets on the Internet to be globally non-deterministic, so as to be robust to failures and reconfigurations.
