Fun with Lambdas: C++14 Style (part 1)Sumant Tambe
If virtual functions in C++ imply design patterns, then C++ lambdas imply what? What does it really mean to have lambdas in C++? Frankly, I don't know but I've a hunch: It's BIG.
Just like virtual functions open doors to the OO paradigm, lambdas open doors to a different paradigm--the functional paradigm. This talk is not a praise of functional programming or some elusive lambda-based library. (Although, I'll mention one briefly that tops my list these days.) Instead, the goal is to have fun while working our way through some mind-bending examples of C++14 lambdas. Beware, your brain will hurt! Bring your laptop and code the examples right along because that may be the fastest way to answer the quiz.
C++11 Idioms @ Silicon Valley Code Camp 2012 Sumant Tambe
C++11 feels like a new language. Compared to its previous standards, C++11 packs more language features and libraries designed to make C++ programs easier to understand and faster. As the community is building up experience with the new features, new stylistic ways of using them are emerging. These styles (a.k.a. idioms) give the new language its unique flavor. This talk will present emerging idioms of using rvalue references -- a marquee feature of C++11 as many renowned experts call it. You will see how C++11 opens new possibilities to design class interfaces. Finally, you will learn some advanced use-cases of rvalue references which will likely make you feel something amiss in this flagship feature of C++11.
Systematic Generation Data and Types in C++Sumant Tambe
This presentation will discuss two classic techniques from the functional domain — composable data generators and property-based testing — implemented in C++14 for testing a generic serialization and deserialization library. We will look at a systematic technique of constructing data generators from a mere random number generator and random type generation using compile-time meta-programming. Along the way, we will discuss monoids, functors, and monads as we encounter them.

Map(), flatmap() and reduce() are your new best friends: simpler collections,...Chris Richardson
Higher-order functions such as map(), flatmap(), filter() and reduce() have their origins in mathematics and ancient functional programming languages such as Lisp. But today they have entered the mainstream and are available in languages such as JavaScript, Scala and Java 8. They are well on their way to becoming an essential part of every developer’s toolbox.
In this talk you will learn how these and other higher-order functions enable you to write simple, expressive and concise code that solve problems in a diverse set of domains. We will describe how you use them to process collections in Java and Scala. You will learn how functional Futures and Rx (Reactive Extensions) Observables simplify concurrent code. We will even talk about how to write big data applications in a functional style using libraries such as Scalding.
(video of these slides available here http://fsharpforfunandprofit.com/fppatterns/)
In object-oriented development, we are all familiar with design patterns such as the Strategy pattern and Decorator pattern, and design principles such as SOLID.
The functional programming community has design patterns and principles as well.
This talk will provide an overview of some of these, and present some demonstrations of FP design in practice.

Design Patterns - Compiler Case Study - Hands-on ExamplesGanesh Samarthyam
This presentation takes a case-study based approach to design patterns. A purposefully simplified example of expression trees is used to explain how different design patterns can be used in practice. Examples are in C#, but is relevant for anyone who is from object oriented background.
Oh Crap, I Forgot (Or Never Learned) C! [CodeMash 2010]Chris Adamson
Abstract: Chances are you code in a language that's either descended from C, inspired by C, or run in an interpreter that itself is written in C. Still... do you actually know how to code in C? Despite its long-standing position as a sort of "lingua franca", an agreed-upon common language, more and more developers are putting together successful, satisfying careers, without ever learning this seminal language. But what if you have to call into C code from your favorite scripting language, or use APIs like OpenGL that are written to be called from C? Many developers find C very challenging, particularly its manual memory-management and other low-level concerns. In this session, we'll show you why you shouldn't be afraid of C, how you can use the skills you already have from the languages you code in today, and how to master structs, enums, typedefs, malloc(), free(), and the rest of C's sharp edges. Examples will be from the point-of-view of the C-skewing iPhone SDK, but will be designed to be broadly applicable and platform-agnostic.
Kafka Tiered Storage separates compute and data storage in two independently scalable layers. Uber's Kafka Improvement Proposal (KIP) #405 describes two-tiered storage, which is a major step towards cloud-native Kafka. It stores the most recent data locally and offloads older data to a remote storage service. Operationally, the benefit is faster routine cluster maintenance activities. In Linkedin, Kafka tiered storage is strongly desired to reduce the cost of running Kafka in the Azure cloud environment. As KIP-405 does not dictate the implementation of remote storage substrate, Linkedin's choice for tiering Kafka in Azure deployments is the Azure Blob Service. This presentation will begin with the motivation behind Linkedin efforts to adopt Kafka Tiered Storage. Next, the architecture of KIP-405 will be discussed. Finally, the Remote Storage Manager for Azure Blobs, which is a work-in-progress, will be presented.

Kafka is a high-throughput, fault-tolerant, scalable platform for building high-volume near-real-time data pipelines. This presentation is about tuning Kafka pipelines for high-performance.
Select configuration parameters and deployment topologies essential to achieve higher throughput and low latency across the pipeline are discussed. Lessons learned in troubleshooting and optimizing a truly global data pipeline that replicates 100GB data under 25 minutes is discussed.
Variants have been around in C++ for a long time and C++17 now has std::variant. We will compare inheritance and std::variant for their ability to model sum-types (a fancy name for tagged unions). We will visit std::visit and discuss how it helps us model the pattern matching idiom. Immutability is one of the core pillars of Functional Programming (FP). C++ now allows you to model deep immutability; we'll see a way to do that using the standard library. We'll explore if `return std::move(*this)` makes any sense in C++. Immutability may be a reason for that.
Remote Log Analytics Using DDS, ELK, and RxJSSumant Tambe

Reactive Stream Processing Using DDS and RxSumant Tambe
In this presentation you will see why Reactive Extensions (Rx) is a powerful technology for asynchronous stream processing. RTI Data Distribution Service (DDS) will be used as the source of data and as a communication channel for asynchronous data streams. On top of DDS, we'll use Rx to subscribe, observe, project, filter, aggregate, merge, zip, and correlate one or more data streams (Observables). The live demo will be very visual as bouncing shapes of different colors will be transformed in front of you using C# lambdas, Rx.NET, and Visual Studio. You will also learn about the new Rx4DDS.NET library that integrates RTI DDS with Rx.NET. Rx and DDS are a great match because both are reactive. Rx is based on the subject-observer pattern, which is quite analogous to the publish-subscribe pattern of DDS. When used together they support distributed dataflows seamlessly. If time permits, we will touch upon advanced Rx concepts such as stream of streams (IGroupedObservable) and how it captures DDS "keyed topics". The DDS applications using Rx4DDS.NET dramatically simplify concurrency to the extent that it can be simply configured.
An Extensible Architecture for Avionics Sensor Health Assessment Using DDSSumant Tambe
Avionics Sensor Health Assessment is a sub-discipline of Integrated Vehicle Health Management (IVHM), which relates to the collection of sensor data, distributing it to diagnostics/prognostics algorithms, detecting run-time anomalies, and scheduling maintenance procedures. Real-time availability of the sensor health diagnostics for aircraft (manned or unmanned) subsystems allows pilots and operators to improve operational decisions. Therefore, avionics sensor health assessments are used extensively in the mil-aero domain. As avionics platforms consist of a variety of hardware and software components, standards such as Open System Architecture for Condition-Based Maintenance (OSA-CBM) have emerged to facilitate integration and interoperability. However, OSA-CBM is a platform-independent standard that provides little guidance for avionics sensor health monitoring, which requires onboard health assessment of airborne sensors in real-time. In this paper, we present a distributed architecture for avionics sensor health assessment using the Data Distribution Service (DDS), an Object Management Group (OMG) standard for developing loosely coupled high-performance real-time distributed systems. We use the data-centric publish/subscribe model supported by DDS for data acquisition, distribution, health monitoring, and presentation of diagnostics. We developed a normalized data model for exchanging the sensor and diagnostics information in a global data space in the system. Moreover, Extensible and Dynamic Topic Types (XTypes) specification allows incremental evolution of any subset of system components without disrupting the overall health monitoring system. We believe, the DDS standard and in particular RTI Connext DDS, is a viable technology for implementing OSA-CBM for avionics systems due to its real-time characteristics and extremely low resource requirements. RTI Connext DDS is being used in other major avionics programs, such as FACE™ and UCS. We evaluated our approach to sensor health assessment in a hardware-in-the-loop simulation of an Inertial Measurement Unit (IMU) onboard a simulated General Atomics MQ-9 Reaper UAV. Our proof-of-concept effectively demonstrates real-time health monitoring of avionics sensors using a Bayesian Network –based analysis running on an extremely low-power and lightweight processing unit.
Overloading in Overdrive: A Generic Data-Centric Messaging Library for DDSSumant Tambe
When it comes to sending data across a network, applications send either binary or self-describing data (XML). Both approaches have merits. Data Distribution Service (DDS) combines the best of both in what’s called “data-centric messaging”. DDS shares the type description once, upfront, and later on sends binary data that meets the type description. You typically use IDL or XSD to specify the types and run them through a code generator for type-safe wrapper APIs for your application in your programming language. Simple and fast! As it turns out, however, C++11 bends the rules once again. In this presentation you will learn about a template-based C++11 messaging library that gives the DDS code generator a run for its money. The types and objects in your C++11 application are mapped to standard DDS X-Types type descriptions and serialized format, respectively, using template meta-programming. If you have never heard about SFINAE you won’t stop talking about it after you see "overloading in overdrive" in this presentation. What’s more? I will share my newfound hatred for std::vector of bool/enums. This presentation will cover DDS-XTypes, DDS_TypeCode, DDS_DynamicData, STL, type_traits, Boost Fusion, and overloading with enable_if (lots and lots of it!).
Communication Patterns Using Data-Centric Publish/SubscribeSumant Tambe
Fundamental to any distributed system are communication patterns: point-to-point, request-reply, transactional queues, and publish-subscribe. Large distributed systems often employ two or more communication patterns. Using a single middleware that supports multiple communication patterns is a very cost-effective way of developing and maintaining large distributed systems. This talk will begin with an introduction of Data Distribution Service (DDS) – an OMG standard – that supports data-centric publish-subscribe communication for real-time distributed systems. DDS separates state management and distribution from application logic and supports discoverable data models. The talk will then describe how RTI Connext Messaging goes beyond vanilla DDS and implements various communication patterns including request-reply, command-response, and guaranteed delivery. You will also learn how these patterns can be combined to create interesting variations when the underlying substrate is as powerful as DDS. We’ll also discuss APIs for creating high-performance applications using the request-reply communication pattern.
Retargeting Embedded Software Stack for Many-Core SystemsSumant Tambe
Novel techniques are needed for high-performance applications to exploit massive local concurrency in many-core systems. Getting software applications to run faster on machines with more cores requires substantial restructuring of embedded software stacks, including applications, middleware, and the operating system (OS). Contemporary software stacks are not designed to exploit hundreds or thousands of cores. New OS and middleware mechanisms must be developed to handle scheduling, resource sharing, and communication in many-core systems. The solution must also provide high-level API to simplify development of concurrent software. In this session, we describe new mechanisms for scheduling and communication for many-core embedded platforms.
Native XML processing in C++ (BoostCon'11)Sumant Tambe
XML programming has emerged as a powerful data processing paradigm with its own rules for abstracting, partitioning, programming styles, and idioms. Seasoned XML programmers expect, and their productivity depends on the availability of languages and tools that allow usage of the patterns and practices native to the domain of XML programming. The object-oriented community, however, prefers XML data binding tools over dedicated XML languages because these tools automatically generate a statically-typed, vocabulary-specific object model from a given XML schema. Unfortunately, these tools often sidestep the expectations of seasoned XML programmers because of the difficulties in synthesizing abstractions of XML programming using purely object-oriented principles. This talk demonstrates how this prevailing gap can be significantly narrowed by a novel application of multi-paradigm programming capabilities of C++. In particular, how generic programming, meta-programming, generative programming, strategic programming, and operator overloading supported by C++ together enable native and typed XML programming.

Acetabularia acetabulum is a single-celled green alga that in its vegetative state is morphologically differentiated into a basal rhizoid and an axially elongated stalk, which bears whorls of branching hairs. The single diploid nucleus resides in the rhizoid.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202
