GamingAnywhere: An Open Cloud Gaming System
Cloud gaming is a promising application of the rapidly expanding cloud computing infrastructure. Existing cloud gaming systems, however, are closed-source with proprietary protocols, which raises the bars to setting up testbeds for experiencing cloud games. In this paper, we present a complete cloud gaming system, called GamingAnywhere, which is to the best of our knowledge the first open cloud gaming system. In addition to its openness, we design GamingAnywhere for high extensibility, portability, and reconfigurability. We implement GamingAnywhere on Windows, Linux, and OS X, while its client can be readily ported to other OS's, including iOS and Android. We conduct extensive experiments to evaluate the performance of GamingAnywhere, and compare it against two well-known cloud gaming systems: OnLive and StreamMyGame. Our experimental results indicate that GamingAnywhere is efficient and provides high responsiveness and video quality. For example, GamingAnywhere yields a per-frame processing delay of 34 ms, which is 3+ and 10+ times shorter than OnLive and StreamMyGame, respectively. Our experiments also reveal that all these performance gains are achieved without the expense of higher network loads; in fact, GamingAnywhere incurs less network traffic. The proposed GamingAnywhere can be employed by the researchers, game developers, service providers, and end users for setting up cloud gaming testbeds, which, we believe, will stimulate more research innovations on cloud gaming systems.
GamingAnywhere is now publicly available at http://gaminganywhere.org.
Cloud Gaming
This document discusses cloud gaming and its support from virtualization and hardware technologies. It begins with an introduction to cloud gaming and its two main types: video streaming and file streaming. It then discusses the architecture of cloud gaming systems and the advantages they provide over traditional gaming. Challenges in cloud gaming like high costs are also outlined. The document proposes that virtualization can help solve these challenges by allowing for scalable, cost-effective gaming environments. It presents the design and implementation of Rhizome, a cloud gaming system that uses virtualization and hardware encoding to provide high-performance gaming over the cloud in a customizable way. In conclusion, the document discusses how cloud gaming is rapidly advancing, especially with 4K capabilities, supported by
Quantifying User Satisfaction in Mobile Cloud Games
We conduct real experiments to quantify user satisfaction in mobile cloud games using a real cloud gaming system built on the open-sourced GamingAnywhere. We share our experiences in porting GamingAnywhere client to Android OS and perform extensive experiments on both the mobile and desktop clients. The experiment results reveal several new insights: (1) gamers are more satisfied with the graphics quality on mobile devices, while they are more satisfied with the control quality on desktops, (2) the bitrate, frame rate, and network delay significantly affect the graphics and smoothness quality, and (3) the control quality only depends on the client type (mobile versus desktop). To the best of our knowledge, such user studies have never been done in the literature.
Srinivas, Nirmalaya - Testing a massively multi-player online game
An online game server's functional and non-functional features lead to non-standard challenges for both architecting as well as testing. This talk starts with an overview and then discusses one testing scenario in depth. We stress particularly on testing the asychronous nature of the application's method calls. A few general approaches of testing such applications terms are alluded to at the end.
Are All Games Equally Cloud-Gaming-Friendly? An Electromyographic Approach
Cloud gaming makes any computer game playable on a thin client without worrying the hardware requirements as before. It frees players from the need to constantly upgrade their computers as they can now play games that host on remote servers with a broadband Internet connection and a thin client. However, cloud games are intrinsically more susceptible to latency than online games because game graphics are rendered on server nodes and thin clients do not possess game state information that is required by delay compensation techniques.
In this paper, we investigate how the response latency would affect users' experience when playing games on clouds and how the impact of latency on players' experience varies across different games. We show that not all games are equally friendly to cloud gaming. The same degree of latency may have very different impact on a game's quality of experience depending on the game's real-time strictness. We thus develop a model that can predict a game's real-time strictness based on the rate of players' inputs and game screen dynamics. The model can be used to enhance players' experience in cloud gaming and optimize data center operation cost simultaneously.

BitSquid Tech: Benefits of a data-driven renderer
BitSquid Tech is a data-driven game engine developed by BitSquid that aims to provide flexibility and fast iteration. Key aspects include supporting hot-reloading of content, utilizing multi-core processors, and having multiple specialized tools instead of a single large editor. The data-driven renderer uses a JSON configuration file to define the entire rendering pipeline, including resources, layers, and resource generators for post-processing, allowing the pipeline to vary dramatically between projects or hardware while remaining high-level and hot-reloadable. This provides significant benefits for flexibility, experimentation, and scaling to different hardware.
Deciphering Agile Big Data
The trend in software development has been changed a lot nowadays. People are expecting predictable features from some unpredictable data. We can now develop software products from raw data, refine raw data to produce business insights and analytic. We are using visualizations, statistics, and machine learning to develop and plan the needful. This is termed as Data Science. Data modelling is the first part of any software product development. So, “Waterfall” is the approach.
During this period, “Agile” approaches has been emerged. Software Development projects are now getting delivered on a stipulated period and budget. Data science is still trapped on waterfall method.
Problem area lies here. Galore of opportunities arrives at the juncture of these two trends of
development. Agile big data is a development methodology which can be utilized to address the same. Session will be focused to explore new approaches and team structures to follow this methodology.

“How We Learnt to Stop Worrying and Live with Uncertainty” – Case Studies fro...India Scrum Enthusiasts Community
Traditionally, businesses like banking and telecom focused high on standardization and national regulation. The development lead times were long. Consequently, the solution providers developed capabilities to influence standards, develop products and interact with the end-service providers. The changing business landscape challenges providers to keep pace. In the slow-moving market, providers honed the ability to run major multi—year projects. Solution Providers became predictable development machinery with extensive mechanisms to enable predictability and control at the expense of flexibility and customer closeness. This led to organizational setups focusing on the alignment with the project structures and deepening the competencies in narrow areas both in the product and in the functional dimensions. The result? Organizational silos with multiple related hand-over challenges.
My talk will cover solutions to these challenges when multiple teams come together to deliver a solution.More Related Content

Deciphering Agile Big Data
The trend in software development has been changed a lot nowadays. People are expecting predictable features from some unpredictable data. We can now develop software products from raw data, refine raw data to produce business insights and analytic. We are using visualizations, statistics, and machine learning to develop and plan the needful. This is termed as Data Science. Data modelling is the first part of any software product development. So, “Waterfall” is the approach.
During this period, “Agile” approaches has been emerged. Software Development projects are now getting delivered on a stipulated period and budget. Data science is still trapped on waterfall method.
Problem area lies here. Galore of opportunities arrives at the juncture of these two trends of
development. Agile big data is a development methodology which can be utilized to address the same. Session will be focused to explore new approaches and team structures to follow this methodology.

“How We Learnt to Stop Worrying and Live with Uncertainty” – Case Studies fro...India Scrum Enthusiasts Community
Traditionally, businesses like banking and telecom focused high on standardization and national regulation. The development lead times were long. Consequently, the solution providers developed capabilities to influence standards, develop products and interact with the end-service providers. The changing business landscape challenges providers to keep pace. In the slow-moving market, providers honed the ability to run major multi—year projects. Solution Providers became predictable development machinery with extensive mechanisms to enable predictability and control at the expense of flexibility and customer closeness. This led to organizational setups focusing on the alignment with the project structures and deepening the competencies in narrow areas both in the product and in the functional dimensions. The result? Organizational silos with multiple related hand-over challenges.
My talk will cover solutions to these challenges when multiple teams come together to deliver a solution.Rubber Meets the Road

Can Agile Enthusiasm See The Organization Through?
The document discusses whether an organization's enthusiasm for agile practices can help it successfully adopt an agile mindset. It notes that while tools and the agile manifesto are important, true agility requires an entrepreneurial, team-oriented and enabling mindset. The presentation was given by Karmath Dangol of CloudFactory to discuss agility in organizations.
Agile HR From the trenches
An Agile transformation often focuses on IT, and at most cases runs into the boundaries of the softer side of the organisation. What if we initiate a transformation which is HR related? which is focused on employee engagement, and which applies Agile principles and the Scrum practice in HR? In this session I’d like to introduce you to the Agile HR manifesto, and share with you my HR agile journey, i hope to inspire you to have your own.
Evolutionary Change
Change is hard and it’s an art to conceptualize a change in any organization. This session about Evolutionary approach for change would guide audience to think about the pros and cons of evolutionary approach over other generic approach.
In my proposed model of Evolutionary Approach, Change starts from Sensing the situation at real time rather proposing a ‘boxed’ solution. Every enterprise is different and to an extent with-in enterprise each organization (or projects) is different. Thus requires deeper Analysis and identification of a fit-for-purpose solution ideas followed by Implementation of solution ideas followed by Measure of the results. Measuring result guides improvement to move in right direction in-place of being biased about the ideas and assuming they would always work. Measure adds value
to manage change effectively and delivers a happier, innovative and better enterprise.
Evolutionary Change Approach’s focus is to deliver measurable business gains by implementing improvements at enterprise.
Software 4.0 : “How” of Building Software Driven Business
Software-driven business models are shaping the business landscape in a big way. Unprecedented growth in technology has helped to create new generation ‘born-in-the-cloud’ business models. These business models have helped newly formed organizations to catch-up with, and often catapulted past, brick & mortar organizations in less than a decade.
‘Born-in-cloud’ business models are built on NextGen systems. NextGen systems are mass personalized, massively distributed, always on and self-adapting system of systems and have broken the boundary between physical and cyber world.
Software 4.0 is a framework for creating NextGen system. It enables mind-set change, develop people competencies, establishes right methodologies for innovation & speed.
Software 4.0 framework leverages nexus of following methodologies / initiatives –
Business Model Canvas for value promise
Design thinking
Hackathon
Modular Architecture
Agile-at-scale
CLM platform & Continuous Engineering
Machine Learning
Software 4.0 ensures NextGen systems are built in iterative, incremental, self-learning and cost-effective manner with superior quality.
Agile Digital Architecture
The Digital Technology is making the enterprises to redefine their strategies and reinvent business models. The customer and market expectations are changing dynamically forcing the organizations to adopt “Agile” processes and systems to these changing business needs. “Developing Agile Digital Architecture’” is an important element for the organizations to succeed. The speaker will address the way the digital technologies are driving the businesses to change their services and operations, and how the organizations should develop the agile digital architectures. The session also covers building business, data, and application and technology architectures in an agile way and thereby meeting the changing business requirements and eventually delivering the business goals.
Governance mechanism to further business agility
Agile transformation has to be accompanied by suitable governance mechanisms such that the metrics and measures conform to newer ways of working. In waterfall methodology it is straightforward – there is a project and a plan, the metrics verify compliance with the plan on triple constraints. Change was not something seen as desirable.
How does this change for agile teams? Do we still continue with “projects”? Do we track utilization or outcomes? Last
Overall this session will delve on the lightweight governance based on #no projects theme and outcome based metrics on business value, throughput, team engagement and system capability.

Workplace Happiness - Is Business Agility Taking us Towards Happy Workplaces?India Scrum Enthusiasts Community
With the increase in population that separates ‘work’ from ‘life’, as if work is absence of life, it becomes increasingly important to study about what happiness means to people at work, so that they can be made to feel alive in their offices too. This session is aimed at introducing two interesting research studies that aimed to do just that. Also, this session helps people understand if business agility keeps us happy in the true sense.
The two studies that this session will discuss about are as follows:
Richard M. Ryan et al’s Self Determination Theory – led to a book Drive by Dan Pink
Mihaly’s Measurement of Flow in Everyday’s life – led to book Flow by Mihaly himself
This session does not just explain these two research works but also will find the commonalities between these and will engage the audience with discussions using leading questions, thereby bringing out personal examples that they can relate to.Wave 2 of Agile: Agile Leadership Redefined
We introduce Wave 2 of Agile as a way to understand the high-performance results that come from Being Agile. We know many in our industry have fallen into the trap or “Doing Agile” – where people lose sight of the objectives and lasting results.
Wave 2 is about Living Agile. It is in how we show up. It is in how we work with people and organizations to shape the culture. It is living Mahatma Gandhi's truth:
“Be the change that you want to see in the world”.
When we focus on our own behaviour, we model Being Agile. This is the only way to invite the Agile Mindset. This is Wave 2 Agile. We stop creating conflict and resistance. We become the effective leaders and influencers of lasting change in our organizations.

Agile Engineering Environment – 2017
In October 2009, I presented a well-received session entitled An Agile Engineering Environment (in 59 Minutes or Less) at an Agile conference in Chengdu, China. From 2009 – 2015 the environment presented in that session remained fundamentally unchanged as our primary internal development environment. By 2015, however, we began seeing the emergence of new tools which build upon the basic premises of that environment, but enable an even more robust environment to be established even more quickly and independently than the 59-minute environment realized in the 2009 session.
In this session, we will briefly introduce the original configuration and see how modern tooling and techniques enable the improved environment to be established in a fraction of the time, enabling even greater agility in our engineering environment.
Management for Agility and Outcomes
There’s a lot left unsaid about achieving and maintaining “enterprise” agility for large MNCs. For geo-distributed teams that are in the “Forming”, and even, “Norming” stages, there is perceived chaos while envisioning and building v1 products. Unlike teams that are already “norming” or “performing”, and have then adopted Agile, these “v1 teams” have a steeper trek to agility. Often, Agile process gives way to tactical execution. This session deals talks about dealing with this situation and maintaining business agility.
Agile Mindset Shifting: Agile For All
An Agile mindset believes that diverse teams with complementary skills are best equipped to thrive in today’s business environments.
Many organizations, working with Agile methodologies, talk about changing mindsets. I know from extensive experience that Agile principles and practices by themselves will not lead to this kind of transformation. A real Agile transformation is about not just doing Agile, but being Agile.
‘Follow Agile’ mindset will only help us get into the water but ‘Being Agile’ mindset will help us swim in the current. Most Agile implementations fail and their practitioners cannot tell why. Managers jump onto the Agile bandwagon, and quickly discover that the change runs much deeper and wider than they’d been told. Worse yet, people decide for or against Agile without understanding it properly. It does not have to be this way. This will be an interactive workshop leading toward the Agility.

Five (Oops!) Six Mistakes You are Making as a Leader
The world of work is transforming at an unrelenting pace – product development is increasingly complex and uncertain, the speed of decisions and delivery are escalating at an exponential pace, customers are demanding more attention and responsiveness, and the workforce is entering with new expectations of engagement. Through all of this, 80% of managers continue to believe they are operating effectively with their employees, yet only 25% of employees agree. Something is wrong! Most leaders are unaware of how their own thoughts and actions are working against their leadership objectives. Ineffective leadership fuels the top impediments limiting organizational agility and growth – the fear of losing control, the resistance to change and contrasting values.
Pete illustrates how leadership agility improves self-awareness, amplifies decision-making, improves outcomes and grows organizational resilience and capacity in highly complex and fast-paced environments. Through the art of story telling from his two decades of personal experience, as well as the experiences of other senior leaders with whom he has coached, Pete spotlights six critical mistakes you may be unaware of in your own leadership practice, how they may be working against your intent, and how to reorient your focus to improve your leadership outcomes.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.
- These are slides of the talk given at IEEE International Conference on Software Testing Verification and Validation Workshop, ICSTW 2022.
