CACM Mar. 2018 - A Programmable Programming Language
 
03:22
In the ideal world, software developers would analyze each problem in the language of its domain and then articulate solutions in matching terms. In the real world, however, programmers use a mainstream programming language someone else picked for them. The Racket project seeks to address this problem by utilizing the emerging idea of language-oriented programming. In this video, Matthias Felleisen discusses "A Programmable Programming Language" (cacm.acm.org/magazines/2018/3/225475), a Contributed Article in the March 2018 issue of Communications of the ACM. (Racket is available at http://racket-lang.org/).
ACM A.M. Turing Award - Whitfield Diffie and Martin E. Hellman
 
04:03
Whitfield Diffe and Martin Hellman received the 2015 ACM A.M. Turing Award for critical contributions to modern cryptography. The ability for two parties to use encryption to communicate privately over an otherwise insecure channel is fundamental for billions of people around the world. On a daily basis, individuals establish secure online connections with banks, e-commerce sites, email servers and the cloud. Diffie and Hellman's groundbreaking 1976 paper, "New Directions in Cryptography," introduced the ideas of public-key cryptography and digital signatures, which are the foundation for most regularly-used security protocols on the Internet today. The Diffie-Hellman Protocol protects daily Internet communications and trillions of dollars in financial transactions.

Celebrating 50 Years of the ACM A.M. Turing Award and Computing's Greatest Achievements
 
04:59
Since its inauguration in 1966, the ACM A. M. Turing Award has recognized major contributions of lasting importance in computing. Through the years, it has become the most prestigious technical award in the field, often referred to as the “Nobel Prize of computing.” During the next several months, ACM will celebrate 50 years of the Turing Award and the visionaries who have received it. Our aim is to highlight the significant impact of the contributions of the Turing Laureates on computing and society, to look ahead to the future of technology and innovation, and to help inspire the next generation of computer scientists to invent and dream. Our celebration will culminate with a conference on June 23 - 24, 2017 at the Westin St. Francis in San Francisco with lively moderated discussions exploring how computing has evolved and where the field is headed. We hope you can join us there, or via the web—we will be streaming the sessions in real time. For more information please visit, http://www.acm.org/turing-award-50
CACM Oct. 2018 - Human-Level Intelligence or Animal-Like Abilities?
 
04:30
The recent successes of neural networks in applications like speech recognition, vision, and autonomous navigation has led to great excitement by members of the artificial intelligence (AI) community, as well as by the general public. Over a relatively short time, by the science clock, we managed to automate some tasks that have defied us for decades, using one of the more classical techniques due to AI research. The triumph of these achievements has led some to describe the automation of these tasks as having reached human-level intelligence. This perception, originally hinted at in academic circles, has gained momentum more broadly and is leading to some implications. In this video, Adnan Darwiche discusses "Human-Level Intelligence or Animal-Like Abilities?" (https://cacm.acm.org/magazines/2018/10/231373), a Contributed Article in the October 2018 Communications of the ACM.
CACM June 2014 - Leslie Lamport, recipient of the 2013 ACM A.M. Turing Award
 
05:59
ACM's 2013 A.M. Turing Award recipient Leslie Lamport was cited for discovering the field of distributed computing systems that work as intended, making it possible for computers to cooperate, avoid error, and reach consensus. The June 2014 issue of Communications of the ACM details Lamport's innovative advances in an article (cacm.acm.org/news/175166), a Q&A, and an original video highlighting some of his renowned colleagues. In his own voice, he asserts that the best logic for stating things clearly is mathematics, a concept, he notes, that some find controversial. Assessing his body of work, he concludes that he created a path that others have followed to places well beyond his imagination. cacm.acm.org
CACM Mar. 2019 - The Seven Tools of Causal Inference
 
05:05
The dramatic success in machine learning has led to an explosion of artificial intelligence (AI) applications and increasing expectations for autonomous systems that exhibit human-level intelligence. These expectations have, however, met with fundamental obstacles that cut across many application areas. One such obstacle is adaptability, or robustness. Machine learning researchers have noted current systems lack the ability to recognize or react to new circumstances they have not been specifically programmed or trained for. Intensive theoretical and experimental efforts toward "transfer learning," "domain adaptation," and "lifelong learning"4 are reflective of this obstacle. In this video, Judea Pearl discusses "The Seven Tools of Causal Inference with Reflections on Machine Learning," a Contributed Article in the March 2019 Communications of the ACM.

ACM Turing Award 2012
 
01:18
Shafi Goldwasser, Silvio Micali Receive 2012 ACM Turing Award For Advances In Cryptography Shafi Goldwasser and Silvio Micali laid the foundations of modern theoretical cryptography, taking it from a field of heuristics and hopes to a mathematical science with careful definitions and security models, precise specifications of adversarial capabilities, and rigorous reductions from formally defined computational problems. Their results, jointly and with others, established the now-standard definitions of security for the fundamental primitives of encryption and digital signatures, and provided exemplary implementations meeting the stated security objectives. Even more importantly, their work helped to establish the tone and character of modern cryptographic research. Jointly and in collaboration with others, they provided stunning innovations in the form of random functions, interactive proofs, and zero-knowledge protocols, with implications beyond cryptography to theoretical computer science in general. http://amturing.acm.org

Keynote - JSON Graph: Reactive REST at Netflix
 
54:58
Every user of a web application wants to believe that all of the data in the cloud is sitting right on their device. Netflix's data platform "JSON Graph" creates this illusion for the web developer. One Model, Available Everywhere. Using an innovative combination of reactive programming techniques and RESTful principles, JSON Graph allows web developers to create a virtual server JSON model for their web application and transparently access it from any cloud-connected device. The Data is the API. Using JSON Graph, Netflix developers retrieve data from the virtual server model the same way they would from an in-memory JSON object. Efficient client/server interactions are ensured by batching concurrent idempotent requests, transparently optimizing requests into point queries, and caching recently-used data. Come learn about the innovative data platform the powers the Netflix UIs, and the new design patterns it enables. Jafar Husain http://dx.doi.org/10.1145/2742580.2742640

01:24
ACM named Leslie Lamport, a Principal Researcher at Microsoft Research, as the recipient of the 2013 ACM A.M. Turing Award for imposing clear, well-defined coherence on the seemingly chaotic behavior of distributed computing systems, in which several autonomous computers communicate with each other by passing messages. He devised important algorithms and developed formal modeling and verification protocols that improve the quality of real distributed systems. These contributions have resulted in improved correctness, performance, and reliability of computer systems. ttp://amturing.acm.org/
Inside Websockets
 
39:12
Author: Leah Hanson Abstract: This talk will focus on how WebSockets work -- the details of the protocol and why they are the way they are. Protocol design is about tradeoffs, and if you pick the wrong tradeoff, you may regret it for a very long time. Were going to take a look at the tradeoffs that the WebSockets protocol made and talk about how you can apply the same principles to your own protocols.

There is more consensus in Egalitarian parliaments
 
25:50
This paper describes the design and implementation of Egalitarian Paxos (EPaxos), a new distributed consensus algorithm based on Paxos. EPaxos achieves three goals: (1) optimal commit latency in the wide-area when tolerating one and two failures, under realistic conditions; (2) uniform load balancing across all replicas (thus achieving high throughput); and (3) graceful performance degradation when replicas are slow or crash. Egalitarian Paxos is to our knowledge the first protocol to achieve the previously stated goals efficiently---that is, requiring only a simple majority of replicas to be non-faulty, using a number of messages linear in the number of replicas to choose a command, and committing commands after just one communication round (one round trip) in the common case or after at most two rounds in any case. We prove Egalitarian Paxos's properties theoretically and demonstrate its advantages empirically through an implementation running on Amazon EC2.

Pivot tracing: dynamic causal monitoring for distributed systems
 
34:34
Authors: Jonathan Mace, Ryan Roelke, Rodrigo Fonseca Abstracts: Monitoring and troubleshooting distributed systems is notoriously difficult; potential problems are complex, varied, and unpredictable. The monitoring and diagnosis tools commonly used today -- logs, counters, and metrics -- have two important limitations: what gets recorded is defined a priori, and the information is recorded in a component- or machine-centric way, making it extremely hard to correlate events that cross these boundaries. This paper presents Pivot Tracing, a monitoring framework for distributed systems that addresses both limitations by combining dynamic instrumentation with a novel relational operator: the happened-before join. Pivot Tracing gives users, at runtime, the ability to define arbitrary metrics at one point of the system, while being able to select, filter, and group by events meaningful at other parts of the system, even when crossing component or machine boundaries. We have implemented a prototype of Pivot Tracing for Java-based systems and evaluate it on a heterogeneous Hadoop cluster comprising HDFS, HBase, MapReduce, and YARN. We show that Pivot Tracing can effectively identify a diverse range of root causes such as software bugs, misconfiguration, and limping hardware. We show that Pivot Tracing is dynamic, extensible, and enables cross-tier analysis between inter-operating applications, with low execution overhead.

Large-scale cluster management at Google with Borg
 
27:55
Authors: Abhishek Verma, Luis Pedrosa, Madhukar Korupolu, David Oppenheimer, Eric Tune, John Wilkes Abstract: Google's Borg system is a cluster manager that runs hundreds of thousands of jobs, from many thousands of different applications, across a number of clusters each with up to tens of thousands of machines. It achieves high utilization by combining admission control, efficient task-packing, over-commitment, and machine sharing with process-level performance isolation. It supports high-availability applications with runtime features that minimize fault-recovery time, and scheduling policies that reduce the probability of correlated failures. Borg simplifies life for its users by offering a declarative job specification language, name service integration, real-time job monitoring, and tools to analyze and simulate system behavior. We present a summary of the Borg system architecture and features, important design decisions, a quantitative analysis of some of its policy decisions, and a qualitative examination of lessons learned from a decade of operational experience with it.

Extracting Energy from the Turing Tarpit
 
32:55
Talk by ACM A.M. Turing Laureate Alan C. Kay during the ACM A.M. Turing Centenary Celebration, June, 2012. Abstract: Part of Turing's fame and inspiration came from showing how a simple computer can simulate every other computer, and so "anything is possible". The "Turing Tarpit" is getting caught by "anything is possible but nothing is easy". One way to get caught is to stay close to the underlying machine with our languages so that things seem comprehensible in the small but the code blows up into intractable millions of lines. What if we used "anything is possible" to make very different kinds of computers which require new learning but the code compactly fits the problem and stays small?

From L3 to seL4 what have we learnt in 20 years of L4 microkernels?
 
33:45
The L4 microkernel has undergone 20 years of use and evolution. It has an active user and developer community, and there are commercial versions which are deployed on a large scale and in safety-critical systems. In this paper we examine the lessons learnt in those 20 years about microkernel design and implementation. We revisit the L4 design papers, and examine the evolution of design and implementation from the original L4 to the latest generation of L4 kernels, especially seL4, which has pushed the L4 model furthest and was the first OS kernel to undergo a complete formal verification of its implementation as well as a sound analysis of worst-case execution times. We demonstrate that while much has changed, the fundamental principles of minimality and high IPC performance remain the main drivers of design and implementation decisions.

Naiad: a timely dataflow system
 
27:37
Naiad is a distributed system for executing data parallel, cyclic dataflow programs. It offers the high throughput of batch processors, the low latency of stream processors, and the ability to perform iterative and incremental computations. Although existing systems offer some of these features, applications that require all three have relied on multiple platforms, at the expense of efficiency, maintainability, and simplicity. Naiad resolves the complexities of combining these features in one framework. A new computational model, timely dataflow, underlies Naiad and captures opportunities for parallelism across a wide class of algorithms. This model enriches dataflow computation with timestamps that represent logical points in the computation and provide the basis for an efficient, lightweight coordination mechanism. We show that many powerful high-level programming models can be built on Naiad's low-level primitives, enabling such diverse tasks as streaming data analysis, iterative machine learning, and interactive graph mining. Naiad outperforms specialized systems in their target application domains, and its unique features enable the development of new high-performance applications.

The Challenges of Writing a Massive and Complex Go Application
 
01:01:46
Author: Ben Darnell Abstract: We opted for Go when building CockroachDB, a scale-out, relational database, because of its support for libraries, interfaces, and tooling. However, it has come with its own frustrations, often related to performance and synchronization. And as for Cgo, RocksDB, and other critical external libraries, we've had to hunt down or develop creative workarounds to ensure they work well the rest of the toolchain. In this talk, we'll share how we've optimized our memory usage to mitigate issues related to garbage collection and improved our use of channels to avoid deadlocks. We will also share creative techniques to integrate non-Go dependencies into the Go build process. ACM DL: http://dl.acm.org/citation.cfm?id=2960085 DOI: http://dx.doi.org/10.1145/2959689.2960085

Michael Stonebraker 2014 ACM A.M. Turing Lecture, June 13 2015
 
01:15:49
Michael Stonebraker has made fundamental contributions to database systems, which are one of the critical applications of computers today and contain much of the world's important data. He is the inventor of many concepts that were crucial to making databases a reality and that are used in almost all modern database systems. His work on Ingres introduced the notion of query modification, used for integrity constraints and views. His later work on Postgres introduced the object-relational model, effectively merging databases with abstract data types while keeping the database separate from the programming language. Stonebraker's implementations of Ingres and Postgres demonstrated how to engineer database systems that support these concepts; he released these systems as open software, which allowed their widespread adoption and their code bases have been incorporated into many modern database systems. Since the pathbreaking work on Ingres and Postgres, Stonebraker has continued to be a thought leader in the database community and has had a number of other influential ideas including implementation techniques for column stores and scientific databases and for supporting on-line transaction processing and stream processing. BACKGROUND Michael Stonebraker is adjunct professor at the Massachusetts Institute of Technology Computer Science and Artificial Intelligence Laboratory (MIT CSAIL) where he is also co-founder and co-director of the Intel Science and Technology Center for Big Data. Prior to MIT, Stonebraker was professor of computer science at the University of California at Berkeley for 29 years. A graduate of Princeton University, Stonebraker earned his master's degree and his Ph.D. from the University of Michigan. Stonebraker received the Software System award with Gerald Held and Eugene Wong for the development of Ingres (IBM’s System R was also recognized). He was the recipient of the inaugural SIGMOD Edgar F. Codd Innovations Award, and received the IEEE John von Neumann Medal. Stonebraker is an ACM Fellow and a member of the U.S. National Academy of Engineering. Read more at http://www.acm.org/turing-lecture-stonebraker .
CACM July 2018 - Digital Nudging: Guiding Online User Choices through Interface Design
 
05:16
Life is full of choices, often in digital environments. People interact with e-government applications; trade financial products online; buy products in Web shops; book hotel rooms on mobile booking apps; and make decisions based on content presented in organizational information systems. All such choices are influenced by the environments in which they take place, and designers of these environments can subtly guide users' behavior by gently "nudging" them toward certain choices. “Digital Nudging: Guiding Online User Choices through Interface Design,” a contributed article in the July issue of Communications of the ACM, shows how designers can consider the effects of nudges when designing digital choice environments.

“Moore’s Law Is Really Dead: What Next?” at ACM Turing 50 Celebration
 
01:00:45
The 50-year reign of Moore’s Law, which delivered a billion-fold increase in transistors per chip, is finally over. Given that transistors are no longer getting much better, that the power budgets of microprocessors are not increasing, and that we’ve already replaced the single power-hungry processor with several energy-efficient ones, the only path to improve energy-performance-cost is specialized hardware. Microprocessors of the future will include special-purpose processors that do one class of computation much better than general-purpose processors. Accelerators for deep neural networks are but one of many potential targets. Panelists will discuss what old doors this seismic change will close and what new doors it will open.

Tango: distributed data structures over a shared log
 
26:50
Distributed systems are easier to build than ever with the emergence of new, data-centric abstractions for storing and computing over massive datasets. However, similar abstractions do not exist for storing and accessing meta-data. To fill this gap, Tango provides developers with the abstraction of a replicated, in-memory data structure (such as a map or a tree) backed by a shared log. Tango objects are easy to build and use, replicating state via simple append and read operations on the shared log instead of complex distributed protocols; in the process, they obtain properties such as linearizability, persistence and high availability from the shared log. Tango also leverages the shared log to enable fast transactions across different objects, allowing applications to partition state across machines and scale to the limits of the underlying log without sacrificing consistency.

Sparrow: distributed, low latency scheduling
 
31:24
Large-scale data analytics frameworks are shifting towards shorter task durations and larger degrees of parallelism to provide low latency. Scheduling highly parallel jobs that complete in hundreds of milliseconds poses a major challenge for task schedulers, which will need to schedule millions of tasks per second on appropriate machines while offering millisecond-level latency and high availability. We demonstrate that a decentralized, randomized sampling approach provides near-optimal performance while avoiding the throughput and availability limitations of a centralized design. We implement and deploy our scheduler, Sparrow, on a 110-machine cluster and demonstrate that Sparrow performs within 12% of an ideal scheduler.

05:25
IllumiRoom is a proof-of-concept system that surrounds a television with projected light, bringing video games, and film experiences out of the TV screen and into the real world. It uses 3D scanning and projected light to change the appearance of the room, induce apparent motion, extend the field of view, and enable entirely new gaming experiences. It's entirely self-calibrating and is designed to work in any room. Hrvoje Benko and Brett R. Jones discuss "IllumiRoom: Experiences Beyond the TV Screen," their Research Highlights article in the June 2015 CACM, http://cacm.acm.org/magazines/2015/6/187312-illumiroom/abstract.

HLF is a world-renowned networking event for mathematicians and computer scientists based on the Lindau Nobel Laureate Meetings. Each September, HLF brings the laureates of the ACM Turing Award, The Abel Prize, the Fields Medal, and the Nevanlinna Prize together with brilliant young researchers from around the world to Heidelberg for a week of intensive exchange.
Sir Tim Berners Lee Receives 2016 ACM A.M. Turing Award
 
06:32
ACM named Sir Tim Berners-Lee, a Professor at Massachusetts Institute of Technology and the University of Oxford, the recipient of the 2016 ACM A.M. Turing Award. Berners-Lee was cited for inventing the World Wide Web, the first web browser, and the fundamental protocols and algorithms allowing the Web to scale. Considered one of the most influential computing innovations in history, the World Wide Web is the primary tool used by billions of people every day to communicate, access information, engage in commerce, and perform many other important activities.

CACM June 2018 David Patterson and John Hennessy, 2017 ACM A.M.  Turing Award
 
08:13
At a time when "making an impact" can feel like a vague or even overwhelming prospect, it's worth reviewing the accomplishments of two scientists who have done just that: ACM A.M. Turing Award recipients John Hennessy and David Patterson. What began as a simple-sounding insight—that you could improve microprocessor performance by including only instructions that are actually used—blossomed into a paradigm shift as the two honed their ideas in the MIPS (Microprocessor without Interlocked Pipeline Stages) and RISC (Reduced Instruction Set Computer) processors, respectively. A subsequent textbook, Computer Architecture: A Quantitative Approach, introduced generations of students not just to that particular architecture, but to critical principles that continue to guide designers as they balance constraints and strive for maximum efficiency. In this video, Hennessy and Patterson discuss their pioneering work, their partnership, and the future of computer architecture.
CACM Feb. 2018 - The Next Phase in the Digital Revolution
 
05:04
Digital Platforms in the computing "cloud" are fundamental features of the digital revolution, entangled with what we term "intelligent tools." An abundance of computing power enabling generation and analysis of data on a scale never before imagined permits the reorganization/transformation of services and manufacturing. How will the increased movement of work to digital platforms provide real and rising incomes with reasonable levels of equality? In this video, John Zysman and Martin Kenney discuss "The Next Phase in the Digital Revolution: Intelligent Tools, Platforms, Growth, Employment," a Contributed Article in the February 2018 issue of Communications of the ACM.

ACM Prize in Computing 2017: Dina Katabi, Massachusetts Institute of Technology
 
03:13
The ACM Prize in Computing is presented to Dina Katabi for creative contributions to wireless networking. Recognized as one of the most innovative researchers in the field of networking, Katabi applies methods from communication theory, signal processing and machine learning to solve problems in wireless networking. Among her contributions, she is cited for co-authoring several highly influential papers on overcoming interference in wireless networks to improve the flow of data traffic. And in inventing a device that seems to be lifted out of the pages of science fiction, she and her team pioneered the use of the wireless signals in the environment to sense humans behind walls, determine their movements and even surmise their emotional states. These trailblazing human-sensing technologies hold out promise for use in several applications of daily life including helping the house-bound elderly, and-perhaps determining survivors within buildings during search and rescue operations. Katabi, along with MIT colleague Piotr Indyk and students, developed a new algorithm, the Sparse Fast Fourier Transform (SFFT) that processes data 10 to 100 times faster than previous methods. The ACM Prize in Computing recognizes an early to mid-career fundamental innovative contribution in computing that, through its depth, impact and broad implications, exemplifies the greatest achievements in the discipline. The award carries a prize of $250,000. Financial support is provided by Infosys. The ACM Prize in Computing was previously known as the ACM-Infosys Foundation Award in the Computing Sciences from 2007 through 2015.
