This document provides an overview of Node.js, including its history as a project started in 2009 by Ryan Dahl, why JavaScript was chosen as the programming language, how its single-threaded and asynchronous event loop model works well for I/O-intensive jobs but can struggle with CPU-intensive tasks, and some gotchas to watch out for like using synchronous APIs, loops, recursion or causing excessive garbage collection which could freeze the process. The document aims to explain what Node.js is and some of its key characteristics and limitations for different use cases.
This document discusses SignalR, an open source library for ASP.NET developers building real-time web functionality. SignalR provides a simple API for adding real-time web functionality to applications, abstracting how real-time connections are established and messages transferred so that it works across technologies like web sockets, forever frames and server-sent events. It supports self-hosting, scaling out, and has clients for .NET, JavaScript and other platforms. SignalR can be used to call client methods from the server and vice versa, enabling two-way communication applications.
This document provides an overview of implementing JSP tag extensions in Java. It discusses:
1. Custom tags which allow creating reusable tags to reduce scripting elements in JSP pages. Tag libraries define custom tags and major features include reusability, readability, maintainability, and portability.
2. Elements of tag extensions including the TLD file which documents the tag library, the tag handler Java class which implements tag functionality, and the taglib directive which identifies the tag library location.
3. Interfaces for developing tag handlers like Tag, IterationTag, BodyTag, and SimpleTag and classes that provide default implementations like TagSupport, BodyTagSupport, and SimpleTagSupport.

Why TypeScript?
with Jeff Francis
OVERVIEW
TypeScript is a type-checked superset of JavaScript that benefits medium-sized to complex JavaScript projects. Why would you want to learn a new language, instead of another JavaScript framework? You have all this existing JavaScript code, so how can you adopt something new without throwing the old stuff out?
This session is about the benefits of using TypeScript on top of JavaScript in your projects, and demonstrate step by step ways of migrating an existing JavaScript project to TypeScript. We will dive into code generated by the compiler and look at resources and tools that make working in TypeScript a pleasurable experience.
OBJECTIVE
To understand when it’s a good idea to use TypeScript.
TARGET AUDIENCE
JavaScript developers.
ASSUMED AUDIENCE KNOWLEDGE
Intermediate JavaScript experience.
FIVE THINGS AUDIENCE MEMBERS WILL LEARN
The basics of TypeScript – types, classes, modules, and functions
How TypeScript’s design makes getting started simple and helps projects
What compiled TypeScript looks like and how to debug
What tools can help take advantage of TypeScript’s type information
How to migrate a JavaScript project to TypeScript

1. The document describes the steps taken to analyze a satellite image, including stacking TIFF images, mosaicking, false color composition, and identifying features.
2. Key features identified include lakes, agriculture, rivers, vegetation, urban settlements, wastelands, and airports based on their color, texture, shape, and brightness.
3. Spectral plots, spatial plots, and surface plots are used to analyze differences between features in band values and across image areas. Statistics like histograms and signature mean plots further characterize the features.

O documento descreve os protocolos de camada de transporte ICMP, UDP e TCP. O ICMP é usado para enviar mensagens de controle e erros na camada de rede. O UDP é um protocolo não orientado a conexão que prioriza a velocidade em detrimento da confiabilidade. O TCP é orientado a conexão e garante a entrega confiável e na ordem correta dos dados.
The document is a presentation on ERDAS IMAGINE software. It discusses layer stacking images, using model maker to add bands, georeferencing images, reprojecting images, and various spatial and radiometric enhancement techniques like filters, histogram equalization, brightness inversion, and haze reduction. Example images are shown to demonstrate the before and after effects of these techniques.
This document provides an overview of the Philippine Elementary Learning Competencies for Science and Health from 2010. It includes a preface describing the vision for science education, followed by sections on the goals and expectations for learning science from Grades 3-6. The standards cover life science, physical science, earth science, and space science. Specific competencies are outlined for each grade level pertaining to human biology, animals, plants and the environment. The document concludes with a note to teachers encouraging hands-on, inquiry-based approaches to teaching science.
Oracle database is a relational database management system. The CREATE TABLE statement is used to create new tables with column names and data types. The ALTER TABLE statement modifies existing table structures by adding, dropping or modifying columns.
The document discusses network security terminology such as threats, attacks, risk analysis, and cryptography. It defines common threats like spoofing, tampering, repudiation, and denial-of-service attacks. The document also outlines the steps for performing risk analysis and includes an exercise asking questions about finding, removing, and preventing vulnerabilities.

Application of Basic Remote Sensing in GeologyUzair Khan
Application of basic remote sensing in Geology. This presentation tries to discriminate the lithology in the Landsat-7 scene located Karachi West. Although other enhanced methodology available to discriminate the rock types, here just a band ratios and simple band combination used for lithology identification.
- TypeScript is a typed superset of JavaScript that adds types, interfaces, and classes but compiles to plain JavaScript. It allows for early detection of bugs through compile-time type checking.
- Some key features of TypeScript include type annotations, access modifiers, interfaces, inheritance, enums, modules, namespaces, and generics. It supports common data types like boolean, string, number, arrays, and functions.
- TypeScript works by compiling TS files to JS files and optional sourcemaps that allow debugging the original TS code. It uses the Node.js runtime and supports editors like VS Code through plugins. Modules are preferred over namespaces for organizing code in larger projects.
This document provides tips and tricks for debugging JavaScript. It discusses common JavaScript mistakes like undefined variables, misspellings, case sensitivity issues, and incorrect brackets or parentheses. It also covers debugging techniques like using alert, console.log, try/catch blocks, and sequentially uncommenting code. The document recommends using developer tools, which allow setting breakpoints and stepping through code line-by-line to debug issues. It concludes with inviting questions from the audience.

Thứ nhất, về tiến bộ KH-CN: Công nghệ lạc hậu từ
50-100 năm so với các nước phát triển, và 20-30
năm so với các nước đang phát triển.
Thứ hai, nguồn vốn đầu tư chưa hợp lý, cơ cấu
chậm thay đổi.
Thứ ba, vấn đề thị trường: sản phẩm của VN dù
được xuất đi nhưng doanh thu không cao.
14. GIẢI PHÁP:
Nông nghiệp: Đưa tiến bộ KH-CN vào các khâu của
SX, tập trung phát triển theo hướng SX lớn…
Công nghiệp: tập trung nguồn lực cho các ngành
VN có ưu thế cạnh tranh, tạo ra sản phẩm xuất
khẩu và thu hút nhiều lao động: Chế biến nông sản
…
Dịch vụ: Phát triển mạnh các ngành dịch vụ phục
vụ sản xuất nông – lâm nghiệp và thuỷ sản, phục
vụ đời sống nông thôn …
