Continuous Delivery? Easy! Just Change Everything (Well, Maybe It Is Not That Easy)
2013
2013 Agile Conference
Preserved Fulltext
Rally Software transitioned from shipping code every eight-weeks, with time-boxed Scrum sprints, to a model of continuous delivery with Kanban. The team encountered complex challenges with their build systems, automated test suites, customer enablement, and internal communication. But there was light at the end of the tunnel -greater control and flexibility over feature releases, incremental delivery of value, lower risks, fewer defects, easier on-boarding of new developers, less off-hours

... and a considerable uptick in confidence. This experience report describes the journey to continuous delivery with the aim that others can learn from our mistakes and get their teams deploying more frequently. We will describe and contrast this transition from the business (product management) and engineering perspectives.

The increasingly dynamic nature of resource discovery and binding in modern large-scale distributed and mobile systems poses significant challenges for existing middleware platforms. Future platforms must provide strong support for adaptive behaviour in order both to maintain and optimise services in the face of changing context. We use a survey of existing middleware systems to develop some core themes that characterise and constrain the ability of these approaches to support the development

La nature toujours plus dynamique de la decouverte et attachement de services en ce qui concerne les larges systemes modernes mobiles et distribues pose des defis significatifs pour les plate-formes logiciels intermediaires. Ces futures plates-formes devront fournir un large support en ce qui concerne le comportement adaptif afin de maintenir et optimiser les services face a un changement de contexte. Nous exploitons une etude des systemes logiciels intermediaires pour developper des themes centraux qui caracterisent et limitent la portée de ces approches dans le developpement de systemes autonomes et adaptifs, et nous exposons des tendances plausibles pour le developpement de futures plates-formes plus appropriees a ces domaines.

We propose an approach to Distributed Information Retrieval based on the periodic and incremental centralisation of full-text indices of widely dispersed and autonomously managed content sources. Inspired by the success of the Open Archive Initiative's protocol for metadata harvesting, the approach occupies middle ground between: (i) the crawling of content, and (ii) the distribution of retrieval. As in crawling, some data moves towards the retrieval process, but it is statistics about the

... nt rather than content itself. As in distributed retrieval, some processing is distributed along with the data, but it is indexing rather than retrieval itself. We show that the approach retains the good properties of centralised retrieval without renouncing to cost-effective resource pooling. We discuss the requirements associated with the approach and identify two strategies to deploy it on top of the OAI infrastructure.

Advocates and critics of target-setting in the workplace seem unable to reach beyond their own well-entrenched battle lines. While the advocates of goaldirected behaviour point to what they see as demonstrable advantages, the critics of target-setting highlight equally demonstrable disadvantages. Indeed, academic literature on this topic is currently mired in controversy, with neither side seemingly capable of envisaging a better way forward. This paper outlines a more fruitful approach, based

... oth on theory and practical experience. Context Advocates of target-setting in the workplace and their critics seem unable to agree on any common ground. This is perhaps not surprising, as there are clear contradictions between the arguments advanced by both sides. On the one hand, there is incontrovertible evidence of the damaging effects of arbitrary numerical target-setting and, yet, on the other hand, there is a significant body of academic evidence supporting the benefits of 'goal-directed behaviour'. So, the obvious question is, "Can such fundamental contradictions be resolved, and, if so, how?" The logical place to start is by reviewing the two competing points of view. In The Red Corner In the red corner stand the advocates of 'goal-directed behaviour'. They point to sundry benefits, such as: "Challenging goals lead to better performance than do easy or vague goals" (Latham & Locke, 1979) . Indeed, Locke and Latham are insistent that "goal-setting theory is among the most scientifically valid and useful theories in organizational science" (Locke, Latham and Erez, 1988); and Happier people. For instance, experiments conducted by the Department of Psychology at Oxford Brookes University, linked to the Oxford Happiness Project (Holden, 1996) , showed that depressed individuals who identified and then worked towards constructive goals became demonstrably happier through this exercise alone. Indeed, goal-directed planning has been shown to initiate activity in the frontal lobes of our brains, which also control our sense of happiness. Hence there seems to be a direct connection between goal-directed behaviour and happiness (all other influencing factors being equal).

As we gain access to increasing volumes of context data, we face the problem of moving this information from the sensors that produce it to the applications that consume it. Our approach to this problem uses gossiping, a probabilistic routing protocol, to disseminate context information throughout the environment. We present on-going work on evaluating the performance of different gossiping protocols for this purpose.

Construct differs from other pervasive systems platforms in a number of key respects. It is completely standardsbased, using RDF as its data exchange model and ZeroConf for resource discovery. It supports a knowledgecentric model of interaction where clients' actions are driven by queries and triggers about the context of the system. It uses gossiping to maintain a consistent state across a distributed data structure, which maximises robustness and scalability and avoids many problems with

Pervasive computing systems require large amounts of information to be available to devices in order to support contextaware applications. Information must be routed from the sensors that provide it to the applications that consume it in a timely fashion. However, the potential size and ad hoc nature of these environments makes the management of communications a non-trivial task. One proposed solution to this problem uses gossiping, a class of probabilistic routing protocol, to disseminate

... xt information throughout the environment. Gossiping algorithms require far less in the way of guarantees about network structure, reliability, and latency than alternative approaches, but are unproven in real world scenarios. We describe the on-going development of a framework for evaluating the performance of these algorithms within the context of pervasive environments.

Pervasive computing is typically highly sensor-driven, but sensors provide only evidence of fact rather than facts themselves. The uncertainty of sensor data will affect each component in a pervasive computing system, which may decrease the quality of its provided services. We provide a general model to represent semantics of uncertainty in different levels (e.g., sensor, lower-level context and higherlevel context). Within our model, fine-grained approaches are applied to evaluate and

We discuss the significant technical issues that were addressed during the design stage and present the solutions we developed to resolve them, including innovative ideas for varying the pulse stretch and suppressing gain depletion by amplifi ed spontaneous emission. Finally we present some results obtained during the commissioning of the laser.

... r than content itself; this grants more 1 efficient use of network resources and wider scope of application. As in distributed retrieval, some processing is distributed along with the data, but it is indexing rather than retrieval; this reduces the costs of content provision whilst promoting the simplicity, effectiveness, and responsiveness of retrieval. Overall, we argue that the approach retains the good properties of centralised retrieval without renouncing to cost-effective, large-scale resource pooling. We discuss the requirements associated with the approach and identify two strategies to deploy it on top of the OAI infrastructure. In particular, we define a minimal extension of the OAI protocol which supports the coordinated harvesting of full-content indices and descriptive metadata for content resources. Finally, we report on the implementation of a proof-of-concept prototype service for multi-model content-based retrieval of distributed file collections.

Existing software systems designed to support learning do not adequately provide for vicarious learning in a crossinstitutional collaborative environment. We have developed an architecture based on role-based access control, which provides the necessary security, robustness, flexibility, and explicit formulation of policy. Such an architecture is general enough to be used in a variety of educational institutions and settings, yet flexible enough to allow a wide range of policies within a single system.
