JS - Basics
This document discusses JavaScript basics including its history, variable types, statements, and best practices to avoid coding horrors. It notes that JavaScript was originally meant for popups and has evolved with AJAX and Node.js. It recommends using simple quotes, JSON, and functions for consistency. For statements, it suggests formatting like if statements with brackets and spaces. It also advises splitting files, using namespaces, and keeping line lengths under 250 characters.
itft-Overview of java language
This document provides an overview of the Java programming language. It introduces Java as an object-oriented language and describes how Java programs are compiled and executed. It then presents examples of simple Java programs, including a "Hello World" program with one class and main method, and a program using a math function. Finally, it shows a program with two classes, one to define a room with length and breadth variables, and another class to calculate the area of a room object.
Why we need to control scope
This document discusses the process of controlling project scope. It defines scope as the set of deliverables or features of a project derived from requirements. Controlling scope is important to monitor progress, ensure deliverables meet requirements, and manage changes. Key inputs for controlling scope are the project management plan, requirements documentation, work performance data, and organizational process assets. Variance analysis is used to compare the actual and planned scope. Important outputs are work performance information, change requests, and updates to plans and documents. Controlling scope helps manage any differences between the planned and implemented scope.

Synchronization is used in multithreaded programming to prevent race conditions when multiple threads access shared resources. It is implemented using monitors in Java - only one thread can own a monitor at a time. The synchronized keyword is used to synchronize methods and blocks of code so only one thread can execute that code at a time. Daemon threads are low priority background threads that do not prevent the JVM from terminating when only daemon threads are running. Thread groups allow grouping of threads to manipulate them collectively.

TDoc - Bringing Documentation to Tool
TDoc is a documentation framework that allows developers to annotate comments in source code to generate documentation. It works by parsing the source code and annotated comments to build an AST, then using a code generator to produce HTML documentation and insert assertions to check preconditions and postconditions specified in the comments. The goal is to help developers understand and work with code, especially older or unfamiliar code, by automatically generating documentation and checks from the comments.
Android code convention
The Android code convention document outlines conventions for Android code contributions and projects. It recommends fully qualifying imports, using Javadoc comments, and avoiding generic exception handling. It also notes conventions that don't strongly matter but improve readability, such as consistent indentation and acronym/field naming. The document advises using TODO comments for incomplete code and provides sources for more details on code conventions.

Writing code that writes code - Nguyen Luong
“The Pragmatic Programmer” admonished us all to “write code that writes code”: use code generators to increase productivity and avoid duplication. The language communities have clearly caught on, as more and more frameworks generate code at compile time: Project Lombok, Google Auto, and more.
This session reviews these approaches including examples of how and why we’d want to do this.
We will see newest Java language tools, write our own AST tranform and look at some amazing libraries based on these techniques.
Bio: Nguyen Luong is a senior java technical lead at Ekino Vietnam. He likes to research new technologies and solve security challenges.

After leaving Pixar, she founded Chapman Lima Productions with her husband and is developing the upcoming film Come Away. Her motto is to stand up for yourself while mentoring others.
Communication barriers
The document discusses barriers to communication. It defines communication as the exchange of information, ideas, thoughts, and emotions so that everyone gains a common understanding of the intended message. It then outlines five main barriers to effective communication: language barriers due to specialist jargon or abstract terms; physical barriers due to distance or visual/accent disconnections; physiological barriers like speech or hearing disorders; psychological barriers such as attitudes and emotions; and cultural barriers relating to differences in gender, age, or diversity. The document concludes by suggesting solutions for overcoming communication barriers like ensuring clarity of thoughts, understanding the audience, getting feedback, using body language, avoiding overload of information, and controlling emotions.
