    1. I enjoy it as a quiet type of game you can play even when you've had a long, tough day. And I don't mind pulling unusable tiles; at least you get to take another one instead of missing your turn. There's just something relaxing about it. After all, lots of people enjoy sitting for hours playing Patience and this is much more entertaining than that.

    1. “Follow your blisters” implies something that you come back to so many times that you eventually move past the blister stage, into toughened skin. Eventually, the activity “marks you” through use and practice, and you develop a special competence. When you practice an activity a bit more obsessively than other people, you build unique character – you earn some wear and some healing that makes you idiosyncratic, and a little unbalanced.It is something that you don’t need to put on your to-do list, something you care enough about to return to repeatedly, even though it causes discomfort. Over time, you develop a layer of protection that enables you to do that something more easily.
    1. When nesting an activity with multiple outcomes, you can wire each terminus to a different route.
    2. For example, an output using Track(:create) will snap to the next possible task that is “magnetic to” :create. That’s how tracks or paths are created.
    3. Semantics are mostly relevant for nesting
    4. Remember, in a railway activity each task has two standard outputs with the “semantics” success and failure.
    5. By using Output(:semantic), you can select an existing output of the task and rewire it.
    6. Why don’t we put the “create user” task onto the failure track, and in case of successfully persisting the new user, we deviate back to the happy path?
    7. the Activity component is the heart of TRB
    8. To implement such an activity, we only need to rewire the second step’s failure output to a new terminus.
    9. Since you can reference outputs by their semantic, you as a modeller only connect conceptual termini to ongoing connections!
    10. it’s a bit as if the following wiring is applied to every task added via #step
    11. Additionally, you may add debugging steps, error handler or rewire the conditions dynamically without touching the original snippet.
    12. Suppose that the validate task was getting quite complex and bloated. When writing “normal” Ruby, you’d break up one method into several. In Trailblazer, that’s when you introduce a new, smaller activity.
    13. Knowing about the wiring mechanics in Trailblazer is one thing. However, the real fun starts with nesting activities. That’s when the ideas of encapsulation, interfaces and reducing dependencies really come into play.
    14. Nesting an activity into another is a bit like calling a library method from another method
    15. the explicit modelling has one massive advantage: all possible outcomes of the nested activity are visible and have to be connected in the outer diagram

    1. Business Process Model and Notation (BPMN) is a standard for business process modeling that provides a graphical notation for specifying business processes in a Business Process Diagram (BPD),[3] based on a flowcharting technique very similar to activity diagrams from Unified Modeling Language (UML).

    1. Matz, alas, I cannot offer one. You see, Ruby--coding generally--is just a hobby for me. I spend a fair bit of time answering Ruby questions on SO and would have reached for this method on many occasions had it been available. Perhaps readers with development experience (everybody but me?) could reflect on whether this method would have been useful in projects they've worked on.

    1. ubjectivity canthen be re-defined as an expanded self, whose relational capacity is notconfined within the human species, but includes non-anthropomorphicelements.

      Like mholder pointed out, this also speaks to Foucault's "Self Writing." In this case, I think the connection to the notebook and/or letter (correspondence) is important, where the "expanded self" is due in large part thanks to the non-anthropomorphic materials the writer interacts with (a la Barad's intra-activity, if I'm making that connect aright).

    3. he addition ofa new con guration can introduce features that aresemantically equivalent. The addition of a new ser-vice for weather predictions by using aforecastfeatureinstead of aweatherfeature will cause the creationof two di erent features with the same semantics
    1. n particular, we note how recent extensions to Activity Theory have addressed theoretical shortcomings similar to our five challenges and suggest directions for bridging the gap between everyday practice and systems support

      theoretical base for the case study.

      Tie this back to HCC readings/critiques by Halverson and Hutchins on distributed cognition.

    2. These extensions increase the complexity of the Activity Theory model but also help to explain tensions present in real-world systems such as when one agent plays different roles in two systems that have divergent goals. Furthermore, this approach provides Activity Theory with a similar degree of agility in representing complex, distributed cognition as competing theoretical approaches, such as Distributed Cognition (Hutchins, 1995).

    1. mporal features. We have then to consider how organizational participants are affected by situations containing temporal features, but also how these actors shape, by their behavior and beliefs, local context according to their needs.

      This provides a good framework for the SBTF study that social coordination practices can sometimes be at odds with the "structures that bear significant temporal features."

      Could this mean data as well as events?

      Is this passage invoking activity theory, if it were an HCI study?

    1. While Activity Theory provides a useful lens for understanding users’ work practices and a language for communicating models of users’ behavior, there are some aspects of work practice that have been shown to be critical for knowledge work but are not captured in the Activity Theory framework. For example, knowledge workers have been shown to rely on the organization of information used in ongoing activities to accomplish their work, particularly when the value or role of that information has not yet been fully determined (Kidd, 1994; Malone, 1983; Mynatt, 1999). Activity Theory alludes to the fact that tools reflect the history of their use, but does not place a strong emphasis on this critical component of knowledge work.

    3. The hierarchical structure of the Boer et al. adaptation of the Activity Theory model can help to reconcile the differences in granularity and the difficulties of supporting collaboration identified in our work; future activity-centered user interfaces might take advantage of the zoomable user interface paradigm or feature control over the level of detail (LOD) represented in the interface to more accurately reflect the depth at which a given user conceptualizes their own tasks or the tasks of their colleagues.

      Boer extension attends to some of the challenges which began this paper

    4. Activity Theory casts a wide but well-defined net around the multifaceted nature of activity, suggesting that the user’s colleagues and the object of the activity are of the utmost importance, but that the tools, social rules, and roles of collaborators within the community must also be reflected back to the user as critical components of that activity. The idea that components of activity reflect their history of use through time suggest several ways for activity-centered systems to support a dynamic working landscape; for example, they might capture past activities in an archive for quick—and potentially automated—reference during related tasks in the future, and that the tools used in previous and ongoing activities (e.g., documents and information resources) both be available at all times and tagged with meta-information about how they have been used in the past

      Further description of how activity theory could incorporate temporality through history (past), dynamic (tempo), automated references (future), and toolsets (past, previous).

    5. Engeström (1987) provides a classic visualization summarizing the structure of an activity (figure 3). This model is based around three mutual relationships: that between the actor (subject) and the community (other actors involved), that between subject and the object (in the sense of objective) of the activity, and that between the object and the community. These mutual relationships are mediated by the other components of activity.

    6. Activity Theory is described both as a guiding framework for analyzing observations of work practice and a language for communicating those findings within the community of practitioners (Halverson, 2001).

      description of Activity Theory

    7. Nardi (1996) argues that one of the inherent strengths of Activity Theory is in its ability to capture the idea of context in user models for HCI, a notion that is gaining momentum particularly with respect to the ubiquitous computing paradigm and as its own design movement, so-called activity-centered design (Gay & Hembrooke, 2003). The world that Gay and Hembrooke envision relies upon design that is not user-centered (which is currently the dominant view in the HCI community) but activity-centered, since Activity Theory provides the right “orientation” for future classes of interactions mediated by ubiquitous computing devices.

    8. Besides the fact that an activity is situated in a network of influencing activity systems, it is also situated in time....In order to understand the activity system under investigation, one therefore has to reveal its temporal interconnectedness....Rather than analyzing an activity system as a static picture of reality, the developments and tensions within the activity system need to be

    9. However, Gay and Hembrooke point out a weakness in the original formulation of Activity Theory: “The model of activity theory...has traditionally been understood as a synchronic, point-in-time depiction of an activity. It does not depict the transformational and developmental processes that provide the focus of much recent activity theory research” (Gay & Hembrooke, 2003).

      Not discussed here but those deveopmental processes have temporal qualities and attributes

    10. In their well-known “activity checklist,” Kaptelinin, Nardi, and Macaulay (1999) identified five basic principles of Activity Theory: 1.Hierarchical structure of activity In Activity Theory, the unit of analysis is an activity which is directed at an objectthat motivates the activity. Activities are composed of conscious, goal-directed actions; different actions may be taken to complete any given goal. Actions are implemented through automatic operations, which do not have goals of their own. This hierarchical structure is dynamic and can change throughout the life of an activity. 2.Object-orientedness Activity Theory holds that humans exist in an broadly-defined objective reality, that is, the things around us have properties that are objective both to the natural sciences and society and culture. 3.Internalization/externalization Activity Theory considers both internal and external actions and holds that the two are tightly interrelated. Internalization is the process of transforming an external process into an internal one for the purposes of planning or simulating an action without affecting the world. Externalization transforms internal actions into external ones and is often used to resolve failures of internal actions and to coordinate actions among independent agents. 4.Mediation A central tenet of Activity Theory is that activity is mediated by tools, and that these tools are created and transformed over the course of the activity so that the culture and history of the activity becomes embedded in the tools. Vygotsky’s definition of tool is very broad; one of the tools he was most interested in was language. 5.Development Activity Theory relies upon development as one of its primary research methodologies; that is, “experiments” often include consist of a subject’s participation in an activity and observation of developmental changes in the subject over the course of the activity. Ethnographic methods that identify the cultural and historical roots of activity are also frequently used.

    1. We’ve made an annual thing out of doing it every year over the Super Bowl. We have an event called Break the Super Bowl, where kids are looking at Super Bowl ads and then remixing them. Then we throw them back up online, if they’re fair use, in real time. We get a bunch of kids together for the Super Bowl and it looks like a regular Super party. We’ve got pizza, and Doritos, and wings, and soda, and all the junk food. But then they’re all working in teams on laptops, and they’re remixing the actual ads from the Super Bowl that go up that night. We have the game playing on a larger screen so that it has a fun party atmosphere, but they’re actually doing something.

      This feels like a great example for anecdote / color / something creative in the final report.
