Slides from the Big Data Gurus meetup at Samsung R&D, August 14, 2013
This presentation covers the high level architecture of the Netflix Data Platform with a deep dive into the architecture, implementation, use cases, and future of Lipstick (https://github.com/Netflix/Lipstick) - our open source tool for graphically analyzing and monitoring the execution of Apache Pig scripts.
Netflix uses Apache Pig to express many complex data manipulation and analytics workflows. While Pig provides a great level of abstraction between MapReduce and data flow logic, once scripts reach a sufficient level of complexity, it becomes very difficult to understand how data is being transformed and manipulated across MapReduce jobs. To address this problem, we created (and open sourced) a tool named Lipstick that visualizes and monitors the progress and performance of Pig scripts.
Netflix - Pig with Lipstick by Jeff Magnusson Hakka Labs
In this talk Manager of Data Platform Architecture Jeff Magnusson from Netflix discusses Lipstick, a tool that visualizes and monitors the progress and performance of Apache Pig scripts. This talk was recorded at Samsung R&D.
While Pig provides a great level of abstraction between MapReduce and dataflow logic, once scripts reach a sufficient level of complexity, it becomes very difficult to understand how data is being transformed and manipulated across MapReduce jobs. The recently open sourced Lipstick solves this problem. Jeff emphasizes the architecture, implementation, and future of Lipstick, as well as various use cases around using Lipstick at Netflix (e.g. examples of using Lipstick to improve speed of development and efficiency of new and existing scripts).
Jeff manages the Data Platform Architecture group at Netflix where he is helping to build a service oriented architecture that enables easy access to large scale cloud based analytical processing and analysis of data across the organization. Prior to Netflix, he received his PhD from the University of Florida focusing on database system implementation.
Google File System was innovatively created by Google engineers and it is ready for production in record time. The success of Google is to attributed the efficient search algorithm, and also to the underlying commodity hardware. As Google run number of application then Google’s goal became to build a vast storage network out of inexpensive commodity hardware. So Google create its own file system, named as Google File System that is GFS. Google File system is one of the largest file system in operation. Generally Google File System is a scalable distributed file system of large distributed data intensive apps. In the design phase of Google file system, in which the given stress includes component failures , files are huge and files are mutated by appending data. The entire file system is organized hierarchically in directories and identified by pathnames. The architecture comprises of multiple chunk servers, multiple clients and a single master. Files are divided into chunks, and that is the key design parameter. Google File System also uses leases and mutation order in their design to achieve atomicity and consistency. As of there fault tolerance, Google file system is highly available, replicas of chunk servers and master exists.

Emotional intelligence was first defined scientifically in 1990 by Mayer and Salovey, building on prior concepts. Goleman later proposed it involves five traits that determine one's EQ. Emotional intelligence involves self and social awareness and management. It is debated whether EQ can be accurately measured, though tests do exist to assess specific skills or provide an overall assessment. While EQ may help predict some life outcomes, it does not determine success on its own, and high IQ individuals like Einstein had low EQ without hindrance. EQ is significant for social and workplace interactions but is not a sole predictor of life outcomes and has limitations as a concept.
This document discusses databases and the evolution from flat files to relational databases. It covers:
1) The limitations of flat files including data duplication, separation of data across files, fixed queries, and proliferation of application programs.
2) The introduction of hierarchical and network databases to try to overcome limitations but these still led to inconsistent and redundant data.
3) An introduction to relational databases which overcome limitations by allowing each record to be of fixed length and each field to contain a single data item. This addresses issues with variable length records in previous approaches.
The document discusses the functions and purposes of translators in computing. It describes:
1) Interpreters and compilers translate programs from high-level languages to machine code. Compilers translate the entire program at once, while interpreters translate instructions one at a time as the program runs.
2) Translation from high-level languages to machine code involves multiple stages including lexical analysis, syntax analysis, code generation, and optimization.
3) Linkers and loaders are used to combine separately compiled modules into a complete executable program by resolving addresses and linking the modules together.
This document discusses common network environments, connectivity, and security issues. It describes how LANs and WANs are organized using different topologies and transmission mediums. It then explains key network components like switches, routers, bridges, and modems - how they connect different types of networks and segments. Finally, it discusses common network environments like the Internet, intranets, and extranets as well as technologies that enable them such as hypertext links, URLs, domain names, and HTML.
The operating system must manage hardware resources, provide an interface between users/software and hardware, and provide services like data security. It schedules programs to make best use of the processor when programs are performing input/output tasks. It uses interrupts to change the normal order of program execution in response to events like I/O device signals. Scheduling aims to maximize system usage, be fair to all programs, and prioritize more important programs when needed.
The document discusses computer architecture and the fetch-execute cycle. It describes the Von Neumann architecture, which uses a single processor that follows a linear sequence of fetching, decoding, and executing instructions. It then explains the fetch-execute cycle in more detail with the steps involved. Finally, it discusses parallel processor systems that can split up the fetching, decoding, and executing stages to improve efficiency.
The document discusses techniques for developing computer systems, including structured systems analysis and design method (SSADM) and data flow diagrams (DFDs). It provides details on the stages of SSADM and the symbols and steps used to develop DFDs. An example of a hotel reservation and payment system is presented as a DFD to illustrate the technique. Project management is also discussed, with an example of building a bungalow broken down into tasks, durations, and dependencies shown in a graph.
The document discusses different ways of representing numerical data in computing systems, including:
1) Binary representation, which converts decimal numbers to binary by repeatedly dividing by column headings and tracking the remainders as 1s and 0s.
2) Negative numbers can be represented using sign-and-magnitude or two's complement methods.
3) Other number systems like octal and hexadecimal are also discussed which use different column headings but the same representation principles.
4) Floating point representation separates a real number into a mantissa and exponent to store fractional numbers more efficiently in binary.
The document discusses how data and databases are valuable to organizations. It provides examples of how stock control systems and sales data can be used to automatically reorder stock. Banks also find customer data valuable for assessing loan risks. Modern communication allows sharing of data worldwide through value added network services and databases. Standards are needed for sharing data accurately between different systems. Computers now aid various forms of communication like voice mail, e-commerce, and video conferencing. The internet allows global communication and advertising. IT training must be continually updated as technology changes, which is altering many work patterns and jobs.
This document discusses different programming paradigms including procedural, object-oriented, and declarative paradigms. It provides examples of code using these paradigms. Specifically, it shows an assembly language program that adds two numbers, a C++ program that calculates the area of a rectangle, and Prolog queries to retrieve information from a database about people's genders and family relationships. It also discusses how parameters are used to pass values to functions in Visual Basic.
This document discusses real-time systems and simulation. It defines a real-time system as one that can react quickly enough to input data to affect the real world. Real-time applications include airline booking systems and nuclear reactor controls. Sensors measure physical quantities and transmit data to processors, while actuators accept signals from processors and initiate physical movements. Simulations allow computers to model real-world systems and scenarios through calculations, enabling testing without real-world risks or costs. Simulations have limitations in predicting truly random or complex human events. Parallel processing is needed for simulations involving vast data, complex relationships, and immense calculations.
This document is an exam for an Advanced Subsidiary Level computing exam. It contains 9 questions testing knowledge of topics like memory addressing, data structures, networks, and software development processes. The exam is 2 hours and contains multiple choice, short answer, and longer explanatory questions.
Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots.
To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?

Bram Verhoef, Head of Machine Learning at Axelera AI, presents the “How Axelera AI Uses Digital Compute-in-memory to Deliver Fast and Energy-efficient Computer Vision” tutorial at the May 2024 Embedded Vision Summit.
As artificial intelligence inference transitions from cloud environments to edge locations, computer vision applications achieve heightened responsiveness, reliability and privacy. This migration, however, introduces the challenge of operating within the stringent confines of resource constraints typical at the edge, including small form factors, low energy budgets and diminished memory and computational capacities. Axelera AI addresses these challenges through an innovative approach of performing digital computations within memory itself. This technique facilitates the realization of high-performance, energy-efficient and cost-effective computer vision capabilities at the thin and thick edge, extending the frontier of what is achievable with current technologies.
In this presentation, Verhoef unveils his company’s pioneering chip technology and demonstrates its capacity to deliver exceptional frames-per-second performance across a range of standard computer vision networks typical of applications in security, surveillance and the industrial sector. This shows that advanced computer vision can be accessible and efficient, even at the very edge of our technological ecosystem.
