Javascript is a dynamic scripting language used widely for client-side web development. It allows asynchronous HTTP (AJAX) requests to update pages dynamically without reloading. Key features include variables, functions, objects, conditionals, closures and exceptions. The DOM represents the structure of a web page and can be manipulated with Javascript to dynamically change content, add/remove elements.
In object-oriented programming, a class is an extensible program-code-template for creating objects, providing initial values for state (member variables) and implementations of behavior (member functions or methods).
The document discusses object-oriented programming concepts in JavaScript. It begins with an overview of how everything in JavaScript is an object, even functions, and how objects have prototypes. It then provides examples of using constructor functions, prototype inheritance, and the extend method to create base classes and subclasses. Config objects and model-view design patterns are also demonstrated. The examples show how to build classes for containers, limited containers, query controllers, and adding map and view capabilities to queries. Resources for further learning are provided at the end.
Cycle.js is a functional and reactive JavaScript framework for building user interfaces based on Observables and declarative code. It uses RxJS Observables to model asynchronous behavior and data flow in applications. This allows the unidirectional data flow of views updating models via intents to be modeled as Observables. The document includes code examples of using Cycle.js with RxJS to build reactive UIs, including handling events, updating state, and generating HTML. It also summarizes how the Cycle.run function coordinates driving the application by connecting sources to sinks.
The document discusses the concept of composition in programming. It provides examples of how to compose objects and functions to maximize code reuse. It promotes writing small, single-purpose functions that can be reused and combined through patterns like chaining and piping. This allows building complex programs from simple, composable parts that work together through universal interfaces like streams.
This contains all the slides used in Silicon Valley Code Camp presentation on Sunday Oct 4, 10:45 session on "Amazing new features in JavaScript". At the end ut also includes the last year presentation covering ES 5

The document provides code examples and explanations for various JavaScript programming techniques. Some examples covered include:
1. Using logical operators and default parameters to handle function arguments concisely.
2. Different methods for converting strings to numbers, setting default object properties, and checking if an object property exists.
3. Techniques for improving loop performance by caching array lengths and merging arrays without creating new objects.
4. Examples of array slicing and truncation, as well as converting array-like objects to arrays.
5. Explanations of equality comparisons, typeof, instanceof, and immediately invoked function expressions.
This document contains code snippets that demonstrate different Angular data binding syntax and features, including property, event, two-way, attribute, class, and style bindings. It also shows structural directives like *ngIf, *ngFor, and ngSwitch, as well as template references and local variables.
Our favorite language is now powering everything from event-driven servers to robots to Git clients to 3D games. The JavaScript package ecosystem has quickly outpaced past that of most other languages, allowing our vibrant community to showcase their talent. The front-end framework war has been taken to the next level, with heavy-hitters like Ember and Angular ushering in the new generation of long-lived, component-based web apps. The extensible web movement, spearheaded by the newly-reformed W3C Technical Architecture Group, has promised to place JavaScript squarely at the foundation of the web platform. Now, the language improvements of ES6 are slowly but surely making their way into the mainstream— witness the recent interest in using generators for async programming. And all the while, whispers of ES7 features are starting to circulate…
JavaScript has grown up. Now it's time to see how far it can go.
In this meetup Eyal Vardi will talk about Angular 2.0 architecture. The session will focus on the main parts of Angular 2.0:
Application Bootstrap
Angular Compiler
Hierarchical Injector
Component Lifecycle Hooks
Change Detector
Renderer
Angular 2.0 & jQuery
Dynamic component creation
Tips & Tricks
Each part will be explained and analyzed. In some cases we will dive into Angular 2.0 source code. Our purpose is to list the Do's & Don’ts of Angular.
The session is mostly targeted for developers which already have some experience with Angular 2.0.
The document discusses Groovy concepts including types, operators, objects, structures, closures, control structures, and methods for strings, lists, and maps. It covers topics such as optional syntax, imports, type checking, numbers, strings, GStrings, lists, maps, enums, operators, date/time operations, and closure usage including delegation and implicit parameters. Groovy allows for optional syntax elements, dynamic typing, closures, and methods to operate on common data types like strings, lists, and maps.
- The document discusses using the Rubeus gem to access Java Swing and JDBC from JRuby.
- Rubeus provides a DSL for easily creating Java Swing windows and accessing databases using JDBC from Ruby code.
- Examples show how to create a basic Swing window with text fields and buttons, as well as execute JDBC queries and access database metadata.
The document summarizes Dmitry Soshnikov's presentation on ECMAScript 6 features at the HelsinkiJS meetup on December 12, 2011. Key features discussed include default function parameters, modules system, quasi-literals for string templates, array comprehensions, maps and weak maps, destructuring assignment, rest operator for function arguments, proxy objects for meta programming, and struct types.
In this talk, Adrian Kashivskyy, Netguru iOS Developer, digs into rarely discussed Swift features, such as literal convertibles, interpolation convertibles, pattern matching, reflection and advanced Objective-C bridging.
The document discusses exception handling in Java. It provides examples of different types of exceptions like RuntimeException, Exception, and Error. It also covers try-catch blocks for exception handling, custom exceptions, and logging exceptions. Finally, it discusses exception handling best practices like checking for null before calling methods.
The document discusses constructors and destructors in C++. It explains that constructors initialize objects and are called automatically when an object is created. Constructors have the same name as the class and do not have a return type. Destructors are called when an object is destroyed to deallocate memory. The document provides an example of a Distance class with overloaded constructors and a member function to add distances defined outside the class.

This document provides an overview and introduction to building a basic fraction calculator app in Objective-C. It begins with an overview of the project architecture using the MVC pattern with a Fraction model class to represent fractions, a Calculator class to perform operations, and a ViewController class to manage the user interface. It then details the implementation of each class, including the Fraction class with methods for creating, modifying, and performing operations on fractions, the Calculator class for setting operands and performing operations, and the ViewController class for handling user interface events and updating the display.
Component lifecycle hooks in Angular 2.0Eyal Vardi
The document discusses Angular change detection and lifecycle hooks. It provides examples of using change detection strategies like OnPush, examples of implementing DoCheck to watch for changes, and summaries of the different lifecycle hooks and when they are called.
JavaScript Fundamentals with Angular and LodashBret Little
The purpose of this presentation is also largely to explain some of the fun parts of JavaScript (dynamic function invocation with reflection, dynamic arguments, etc). I don't necessarily encourage putting complex logic throughout your templates with lodash, though there may be times it is appropriate.
Lets talk about lodash and how it can easily be married to Angular. Using a six line filter, I will expose the power of lodash directly within angular templates. This will be an introduction to lodash, angular templates, and we'll talk about scope and reflection within JavaScript.
Lodash is a JavaScript library that provides utility functions for common programming tasks like array, object and string manipulation, as well as functions for chaining, currying and binding. It includes methods for filtering, sorting, mapping, reducing, currying, binding and templating JavaScript objects and arrays. Lodash wraps values to enable method chaining and provides both chainable and non-chainable wrapper methods.
This document discusses operator overloading in C++. It begins by defining operator overloading as giving special meanings to operators for user-defined data types. It then covers overloading unary and binary operators using member functions and friend functions. Some key points include: only existing operators can be overloaded, binary operators take operands as arguments, and type conversions between basic and user-defined types require custom conversion routines like constructors or casting functions. The document also provides examples of overloading operators for complex numbers and strings.
Type safe embedded domain-specific languagesArthur Xavier
Language is everything; it governs our lives: from our thought processes, our communication abilities and our understanding of the world, all the way up to law, politics, logic and programming. All of these domains of human experience are governed by different languages that talk to each other, and so should be your code. Haskell provides all the means necessary—and many more—to easily and safely use embedded small languages that are tailored to specific needs and business domains.
In this series of lectures and workshops, we will explore the whats, whys and hows of embedded domain-specific languages in Haskell, and how language oriented programing can bring type-safety, composability and simplicity to the development of complex applications.

Android Developer Group Poznań - Kotlin for Android developers
STXInsider example project in Kotlin:
https://github.com/kosiara/stx-insider
Kotlin - one of the popular programming languages built on top of Java that runs on JVM. Thanks to JetBrains support and excellent IDE integration, it’s an ideal choice for Android development. 100% Java compatibility, interoperability and no runtime overhead is just the beginning of a long list of strengths. Kotlin is supposed to be a subset of SCALA, has clear benefits for developers on one hand and keeps short compile times on the other.
As a mobile team we got interested in Kotlin a few months before its final release which gave us time to test it thoroughly before production use. The language has some clear advantages for an Android programmer - it enables migration from Java projects that have been under development for some time already. Java&Kotlin coexistence simplifies Kotlin introduction as only new functionality is written in JetBrain’s new language leaving all the legacy code untouched.
Transitioning gives the developer an opportunity to use lambdas, new syntax for data objects, extension functions to easily expand Android SDK’s classes functionality and infix notation to write DSL-like structures. Almost all the libraries you use today will work with Kotlin thanks to 100% Java compatibility. The same is true for Android SDK classes - all of them will seamlessly work with the new programming language. Kotlin gives you more choice when it comes to reflection, creating documentation and being null-pointer safe. Android works great with it out of the box so you won’t need to change your development habits.
Our production project in Kotlin turned out to be a success after 4 months of development. We had 0 bugs related to Kotlin as a programming language. Our code footprint is almost 30% smaller thanks to JetBrain’s, we benefit from nullpointer safety, closures, translated enums, data objects and use infix notation for logging and displaying Snackbars.
===========
In this presentation you'll find basic use cases, syntax, structures and patterns. Later on Kotlin is presented in Android context. Simple project structure, imports and Kotlin usage with Android SDK is explained. In the end cost of Kotlin compilation is presented and the language is compared to SCALA and SWIFT.
We look at the positive impact new syntax can have on boilerplate removal and readability improvement.
Kotlin really shines in Android development when one looks at “Enum translation”, “Extension functions”, “SAM conversions”, “Infix notation”, “Closures” and “Fluent interfaces” applied to lists. The talk, however, compares language-specifics of Java & Kotlin in terms of “Type Variance”, “Generics” and “IDE tools” as well.
The document discusses Kotlin DSL and how it can be used to create domain-specific languages. It provides examples of using Kotlin features like operators, lambdas, and extensions to build DSLs for validation rules, UI layouts, dependency injection, and more. Key points include how functions, operators, and properties can be overridden or extended to define new syntax and behaviors for DSLs, and how inline functions allow embedding DSL code without additional overhead.

The Ring programming language version 1.5.1 book - Part 32 of 180Mahmoud Samir Fayed
The document provides documentation on Ring programming language functions and features. It summarizes the use of various functions in the stdlib.ring library including puts(), print(), print2Str(), getstring(), getnumber(), apppath(), justfilepath(), justfilename(), value(), times(), map(), filter(), split(), splitmany(), newlist(), capitalized(), isspecial(), isvowel(), linecount(), factorial(), fibonacci(), isprime(), and sign(). Examples are given to demonstrate the usage of each function.
Higher Order Components and Render PropsNitish Phanse
The document discusses higher order components (HOCs) in React. It begins by introducing HOCs as functions that take a component and return a new component. Various examples of HOCs are provided, including for purposes like code splitting, server side rendering, data tracking, and component logging. Key tips are provided, such as avoiding HOCs inside render and that refs are not passed through. The document also discusses how render props can be used as an alternative pattern to HOCs in some cases, and provides examples of common use cases like async data fetching and geolocation. It concludes by explaining that HOCs can also be created using a render prop approach.
The Ring programming language version 1.7 book - Part 48 of 196Mahmoud Samir Fayed
This document provides code examples and documentation for Ring's web library (weblib.ring). It describes classes and methods for generating HTML pages, forms, tables and other elements. This includes the Page class for adding common elements like text, headings, paragraphs etc., the Application class for handling requests, cookies and encoding, and classes representing various HTML elements like forms, inputs, images etc. It also provides an overview of how to create pages dynamically using View and Controller classes along with Model classes for database access.
Software written in such way might look unconventional, and has a bit of a learning curve. The talk is to show that the advantages it brings make it a viable choice.
This presentation considers certain specific features of C++11 and additions to STL library (uniform initialization, new containers and methods, move semantics).

Think Async: Asynchronous Patterns in NodeJSAdam L Barrett
JavaScript is single threaded, so understanding the async patterns available in the language is critical to creating maintainable NodeJS applications with good performance. In order to master “thinking in async”, we’ll explore the async patterns available in node and JavaScript including standard callbacks, promises, thunks/tasks, the new async/await, the upcoming asynchronous iteration features, streams, CSP and ES Observables.
En vieux bourlingueur du langage Swift, Grégoire Lhotellier viendra nous présenter les séquences et les collections du nouveau langage d’Apple. Il nous briefera sur l’essentiel de ce qu’il faut en savoir et ce qu’elles changent par rapport à leurs équivalent Objective-C.
This document compares features of Kotlin and Ceylon to Java, including null safety, immutability, generics, type inference, traits/interfaces, operators, functions, and DSL capabilities. It also briefly mentions modularity and provides demo links and contact information for Kotlin and Ceylon.
Stamps - a better way to object compositionVasyl Boroviak
The document discusses an approach called "stamps" for composing object behaviors in a declarative way, as an alternative to class inheritance. Stamps are like classes/factories but specify behaviors through composable metadata rather than inheritance. A stamp implementation is shown that allows defining initializers, methods, properties, and static properties and composing them to create new stamps. The stamps approach is compared to configuring classes through annotations and dependency injection in Java.

2018/11/09 の Swift 愛好会の LT で『Swift の let した変数に値を再代入してみよう』という問題提起をするのに使ったオープニング的なスライドです。
このスライドに「解答」は含まれていないので、この話題をきっかけにあれこれ試行錯誤して、さらにはそこから『どうして2回、代入することができたのか』みたいな理由を考える糸口にしてもらえたら嬉しいです。
This code snippet shows two switch statements in Swift. The first switch statement matches on a variable v and prints different outputs depending on which pattern matches. The second switch statement matches on a device variable and can match multiple patterns on one case or use a where clause to check for a suffix, printing outputs accordingly.
The document discusses control flow statements in Swift including if/else statements to check conditions, switch statements to check multiple options, and looping statements like for-in, while and repeat-while. It also provides examples of if let to safely unwrap optionals and the nil coalescing operator ?? to handle nil values.

Speaker:
- Jianjian Xie (Staff Software Engineer, Alluxio)
As Trino users increasingly rely on cloud object storage for retrieving data, speed and cloud cost have become major challenges. The separation of compute and storage creates latency challenges when querying datasets; scanning data between storage and compute tiers becomes I/O bound. On the other hand, cloud API costs related to GET/LIST operations and cross-region data transfer add up quickly.
The newly introduced Trino file system cache by Alluxio aims to overcome the above challenges. In this session, Jianjian will dive into Trino data caching strategies, the latest test results, and discuss the multi-level caching architecture. This architecture makes Trino 10x faster for data lakes of any scale, from GB to EB.
What you will learn:
- Challenges relating to the speed and costs of running Trino in the cloud
- The new Trino file system cache feature overview, including the latest development status and test results
- A multi-level cache framework for maximized speed, including Trino file system cache and Alluxio distributed cache
- Real-world cases, including a large online payment firm and a top ridesharing company
- The future roadmap of Trino file system cache and Trino-Alluxio integration

Measures in SQL (SIGMOD 2024, Santiago, Chile)Julian Hyde
SQL has attained widespread adoption, but Business Intelligence tools still use their own higher level languages based upon a multidimensional paradigm. Composable calculations are what is missing from SQL, and we propose a new kind of column, called a measure, that attaches a calculation to a table. Like regular tables, tables with measures are composable and closed when used in queries.
SQL-with-measures has the power, conciseness and reusability of multidimensional languages but retains SQL semantics. Measure invocations can be expanded in place to simple, clear SQL.
To define the evaluation semantics for measures, we introduce context-sensitive expressions (a way to evaluate multidimensional expressions that is consistent with existing SQL semantics), a concept called evaluation context, and several operations for setting and modifying the evaluation context.

Consistent toolbox talks are critical for maintaining workplace safety, as they provide regular opportunities to address specific hazards and reinforce safe practices.
These brief, focused sessions ensure that safety is a continual conversation rather than a one-time event, which helps keep safety protocols fresh in employees' minds. Studies have shown that shorter, more frequent training sessions are more effective for retention and behavior change compared to longer, infrequent sessions.
Engaging workers regularly, toolbox talks promote a culture of safety, empower employees to voice concerns, and ultimately reduce the likelihood of accidents and injuries on site.
The traditional method of conducting safety talks with paper documents and lengthy meetings is not only time-consuming but also less effective. Manual tracking of attendance and compliance is prone to errors and inconsistencies, leading to gaps in safety communication and potential non-compliance with OSHA regulations. Switching to a digital solution like Safelyio offers significant advantages.
Safelyio automates the delivery and documentation of safety talks, ensuring consistency and accessibility. The microlearning approach breaks down complex safety protocols into manageable, bite-sized pieces, making it easier for employees to absorb and retain information.
This method minimizes disruptions to work schedules, eliminates the hassle of paperwork, and ensures that all safety communications are tracked and recorded accurately. Ultimately, using a digital platform like Safelyio enhances engagement, compliance, and overall safety performance on site. https://safelyio.com/
