Welcome to rx java2
RxJava is very powerful tool which helps Android code to understand and maintain very easily. Using RxJava, application can be created with lesser bug. With RxJava many complex tasks can be accomplished easily and without errors. As RxJava is new for Android developer, they might have questions like Why? How? When? In this talk, audience will have very useful RxJava information with example of implementing in Applications.
Dom parser
The document discusses two common XML parsers - DOM and SAX. DOM builds an in-memory tree representation of the entire XML document, allowing random access. SAX is event-based and parses the document sequentially, notifying the application of elements and attributes through callback methods. DOM is used when random access or rearranging elements is needed, while SAX is better for large documents or streaming data. Common DOM and SAX methods are also outlined.
JavaScript - Chapter 12 - Document Object Model
What is the DOM?
The DOM is a W3C (World Wide Web Consortium) standard.
The DOM defines a standard for accessing documents:
"The W3C Document Object Model (DOM) is a platform and language-neutral interface that allows programs and scripts to dynamically access and update the content, structure, and style of a document."
The W3C DOM standard is separated into 3 different parts:
Core DOM - standard model for all document types
XML DOM - standard model for XML documents
HTML DOM - standard model for HTML documents
The HTML DOM (Document Object Model)
When a web page is loaded, the browser creates a Document Object Model of the page.
The HTML DOM model is constructed as a tree of Objects.
With the HTML DOM, JavaScript can access and change all the elements of an HTML document.
Error Handling in Swift
Swift uses throws and do/catch for error handling. It has limitations like lacking type information and not working for asynchronous code. The Result type is a good alternative that represents values or errors for both synchronous and asynchronous functions. Exceptions are for crashes and unrecoverable errors, while assertions verify assumptions at debug time.
Java XML Parsing
This document summarizes key aspects of XML including:
- XML is a text-based format for describing data structures that is both human and machine readable.
- XML became a W3C standard in 1998 and is commonly used for exchanging data between disparate systems.
- Java can be used to generate, access, format, parse, validate, and transform XML data.
- XML documents have a root element containing other nested elements and attributes to describe hierarchical data.
- Well-formed XML documents follow syntax rules for proper nesting of start/end tags and quotes around attribute values.
- XML parsers like SAX and DOM are used to read XML documents sequentially or build a navigable tree structure in memory
Xml And JSON Java
This document discusses different ways to parse XML and JSON documents in Java, including DOM, SAX, StAX for XML and common JSON libraries for Java. It provides examples of parsing XML using DOM and SAX, and generating XML and JSON documents from Java.

It begins by defining functional programming as treating computation as the evaluation of mathematical functions and avoiding changing state and mutable data. It then discusses key concepts like mathematical functions, immutability, and pure functions. It provides examples of functional techniques in C# like option types, pattern matching, currying, and local functions. The key takeaways are to use pure functions, write side-effect free code, prefer immutability, and learn functional programming.
6 xml parsing
The document discusses XML parsing and processing. It describes two main approaches:
1) Simple API for XML (SAX) - Parses XML as a sequence of events by using event handlers for start/end tags. This is faster but requires processing elements sequentially.
2) Document Object Model (DOM) - Parses XML into a tree structure of nodes that can be randomly accessed. This allows non-sequential access but uses more memory.
It also discusses the Java API for XML Processing (JAXP) which provides a standardized way to access SAX and DOM parsers from Java code.
32sql server
The document provides an overview of input/output streams and serialization in C#. It discusses how streams are used for reading and writing files and describes classes like FileStream, StreamWriter, and StreamReader that provide methods for working with files. It also explains serialization and deserialization in C# - the processes of converting an object into a byte stream and back, and describes how to apply the SerializableAttribute to allow objects to be serialized.

It begins with an introduction to the speaker, Oleg Tsal-Tsalko, and provides an overview of Java 8 streams including their benefits and common operations. It then covers lambda expressions, functional interfaces, and how lambdas and streams have influenced existing Java classes. The document concludes by providing instructions for downloading a test project to practice using lambdas and streams.
Sax parser
The SAX parser is an event-based XML parser that does not build a DOM tree. It reads XML documents sequentially and notifies registered handlers of parsing events like start elements, end elements, and character data. SAX is useful for large documents since it has a smaller memory footprint than DOM. Handlers implement callback methods to process events. The DefaultHandler class provides empty implementations of required handler interfaces.
30csharp
This document discusses delegates in C#, which are similar to function pointers in C/C++. Delegates allow methods to be passed as arguments and stored for later invocation. The document explains that delegates store references to methods, can reference static or instance methods, and are type-safe. It also covers declaring delegates, instantiating delegates by storing method references, and using single-cast versus multi-cast delegates which can store references to multiple methods and invoke them in sequence.
Xml parsing
This document discusses different approaches to parsing XML documents in Java, including DOM, SAX, and StAX parsers.
It begins by explaining that an XML parser reads XML files and makes the information available to applications. It then describes two main parsing approaches: tree-based APIs like DOM that build an in-memory model of the XML document, and event-based APIs like SAX and StAX that parse the document sequentially and throw events.
DOM parsers create a full object model of the XML document that allows random access but uses more memory. SAX is a push-style event-based parser that is more memory efficient but provides less control. StAX is a pull-style parser that gives clients full control

Functional programming with Scala
Scala is a multi-paradigm programming language that blends object-oriented and functional programming. It is designed to express common programming patterns in a concise, elegant, and type-safe way. Scala runs on the Java Virtual Machine and interoperates seamlessly with Java, but also integrates concepts from languages such as Haskell, ML and Ruby. Some key features of Scala include support for functional programming, a static type system with type inference, pattern matching, actors and immutable data structures.
XML SAX PARSING
This document provides an overview of SAX and DOM, which are APIs for parsing XML documents. It discusses:
- SAX and DOM are standards for XML parsers that allow reading and interpreting XML files. SAX is event-based and reads XML sequentially, while DOM loads the entire XML document into memory allowing random access.
- SAX works through callbacks, where the parser calls methods supplied by the application to handle events like start elements, end elements, and character data.
- A simple SAX program is demonstrated using two classes - one contains the main method and parses the XML, while the other implements handler callbacks.
- Key differences between SAX and DOM are that DOM provides random access to
Angular - Chapter 2 - TypeScript Programming
TypeScript lets you write JavaScript the way you really want to. TypeScript is a typed superset of JavaScript that compiles to plain JavaScript. TypeScript is pure object oriented with classes, interfaces and statically typed like C# or Java. The popular JavaScript framework Angular 2.0 is written in TypeScript. Mastering TypeScript can help programmers to write object-oriented programs and have them compiled to JavaScript, both on server side and client side.
Functions & closures
Scala supports first-class functions that can be passed as arguments to other functions or stored in variables. Functions can be defined as method members or as anonymous function literals. Function literals allow defining unnamed functions inline. Functions in Scala support closures, where functions can close over variables in the enclosing scope. This allows functions to access variables that are not passed in as arguments. The document discusses various ways to define functions in Scala including local functions, function literals, partially applied functions, and repeated parameters.

Json – java script object notation
This document discusses JSON (JavaScript Object Notation), its properties as a data format, how it works, and its advantages for use with AJAX. JSON is a lightweight data format that represents simple data types like strings, numbers, and booleans, as well as more complex data structures. It is human-readable and can be easily parsed into a JavaScript object. Compared to XML, JSON is simpler to use with AJAX due to its direct mapping to JavaScript objects and easier element access. However, security concerns arise from its readability on the client-side. The document recommends using JSON for browser-based applications that require medium data transfer.
Json
JSON is a lightweight data format that can represent complex data structures like objects and arrays. It is useful for AJAX applications because JSON data can be easily evaluated and accessed in JavaScript. JSON has advantages over XML in AJAX as data can be accessed at any depth without additional processing, and JSON syntax is simpler. However, using JSON in AJAX also raises security concerns due to the ability of malicious scripts to access sensitive transmitted data.

It defines AJAX as a group of interrelated technologies that allow asynchronous data retrieval without page reloads. The key aspects covered include the XMLHttpRequest object for asynchronous client-server communication, callback functions, properties and methods. It also introduces web services, describing how to create, publish, test and consume a web service, as well as using SOAP.
AJAX
Ajax allows for asynchronous retrieval of data from a server in the background without reloading the page. It uses a combination of technologies like XMLHttpRequest, JavaScript, and DOM to make asynchronous calls to a server and update portions of a page without reloading. The document then provides an example of how an Ajax interaction works, from making an asynchronous request to a server to processing the response and updating the HTML DOM.

Pascarello_Investigating JavaScript and Ajax Security
The document discusses JavaScript and Ajax security. It provides background on the presenter and outlines what will be investigated, including the Ajax model, form hacks, cross-site scripting (XSS), and other injections. It then discusses the basics of Ajax, including the XMLHttpRequest object and its methods. It covers potential security issues with Ajax and demonstrates simple scripted attacks on a server.
Ajax Fundamentals Web Applications
1. AJAX allows web applications to asynchronously retrieve and display data from a server without reloading the entire page.
2. AJAX can be used in Domino applications to dynamically retrieve data from the server like validating entries, looking up names, or getting category lists.
3. Making an AJAX request involves creating an XMLHttpRequest object, opening a GET request to a URL, setting an onreadystatechange handler, and sending the request. The response is then parsed as XML.
Ajax
The document discusses AJAX (Asynchronous JavaScript and XML), which allows web pages to be updated asynchronously by exchanging data with a web server behind the scenes, without reloading the entire page. It provides an overview of the basic objects and steps needed to make AJAX work, including the XMLHttpRequest object, how servers respond, and using the response. It then contrasts the traditional synchronous web page model with AJAX's asynchronous approach. The document also covers the basics of writing AJAX applications, including creating XMLHttpRequest objects, sending requests, handling responses, and using properties and methods. Finally, it provides a skeleton for a general AJAX application and an example to get the time from the server without refreshing the whole page.

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

AJAX and JSON
- 2. Lecture Outline JSON AJAX
- 4. JSON http://www.json.org/ A lightweight data-interchange format. Humans readable. Easy for machines to parse and generate. A text format that is completely language independent. An ideal data-interchange language.
- 5. JSON (Cont’d) Built on two structures: A collection of name/value pairs (object) An object begins with { and ends with }. Each name is followed by : and the name/value pairs are separated by ‘,’ . An ordered list of values (array) An array begins with [ and ends with ]. Values are separated by ‘,’ . A value can be a string in double quotes, or a number, or true or false or null, or an object or an array.
- 6. JSON (Cont’d) There are libraries in nearly all languages to parse JSON files. In JavaScript, these libraries contain function to convert from objects to json text and vice versa.
- 9. AJAX Allows client-side JavaScript to request and receive data from a server without refreshing the web page. Only partial reload occurs Jesse James Garrett originally coined the term Ajax in 2005. (www.adaptivepath.com/publications/essays/archives /000385.php ). Let web applications look and behave more like desktop applications than web sites,
- 11. Steps to send a simple ajax request 1. Create XMLHttpRequest Object 2. Open the request, set the HTTP method and URL 3. Set callback for onreadychange 4. Send asynchronous request 5. Create an event to call the previous steps
- 13. Sending Request var xhr = new XMLHttpRequest(); xhr.onreadystatechange = myCallback; xhr.open('GET', 'somefile.txt', true); xhr.send('');
- 14. For Cross-browser compatibility
- 15. readyState values Value Description 0 Uninitialized 1 Loading 2 Loaded 3 Interactive 4 Complete
- 16. Some status values Value Description 200 Ok 204 No content 401 UnAuthorized 404 Not Found 411 Request Timeout
- 17. Processing Request function myCallback() { if (xhr.readyState < 4) { return; } if (xhr.status !== 200) { alert('Error!'); // the HTTP status code is not OK return; } alert(xhr.responseText); }
- 18. Try Ajax Use Developer tools
