It's better to know the story of the technology you work, you need to know why it's created, what are the problems it solves.
Here, you will know the story of the most famous technology.
Man, It's Java
This document discusses polyglot or multi-language programming. It defines polyglot programming as knowing many programming languages and being able to use them correctly. It notes that polyglot programmers work subtly in the background rather than seeking attention like "rockstar programmers." It encourages becoming a polyglot programmer through deliberate practice, participating in language and platform communities, taking on projects, and being willing to take risks. It also discusses some challenges of being a polyglot programmer like lack of revenue potential or chance to practice if employers are not open to the approach.
The document outlines a futuristic programming language that could be controlled using voice instead of typing code. It would integrate with search engines and allow objects to be declared in 3D. Debugging would use models like water flow or an adventure game. The conclusion questions whether such an advanced language could exist within 10 years and if developers would still need to use low-level languages like assembly.

This document discusses several key advantages of the Java programming language and platform:
1) Write Once, Run Anywhere - Java code can run on any system that supports the Java Virtual Machine.
2) Security - The Java platform allows running untrusted code securely by restricting what it can access.
3) Network-centric Programming - Java makes it easy to build networked and client-server applications.
4) Dynamic and Extensible - Java programs can dynamically load new classes as needed at runtime.
Java was created in the early 1990s by James Gosling and his team at Sun Microsystems. It was originally designed for interactive television but was found to be better suited for use on the internet. In 1995, Sun Microsystems released Java 1.0 and it became popular for developing web applications and applets due to its cross-platform capabilities. Today Java is widely used across many applications and devices due to its portability and ability to write code once and run anywhere. Some key aspects of Java include its object-oriented design, support for multithreading, and capacity for distributed applications through remote method invocation.

- The goal is to design a new programming language by combining common qualities from two existing languages.
- When designing a new language, it is important to consider aspects like syntax, semantics, data types, control structures, modularity, and libraries/frameworks.
- The language design should aim to take useful features from other languages while avoiding their shortcomings to create a language that is efficient, readable, and meets modern programming needs.
This document discusses the design of a smart emotion-based music player with a sleep alert system. The proposed system uses a camera to capture a user's facial expressions in order to analyze their emotions. Based on the emotion detected, the music player will select music accordingly. The system also monitors eye blinking and yawning frequency to detect sleepiness and will alert the user. The goal is to introduce an application of facial expression recognition technology and develop a music player that responds to user emotion and alerts them if sleepy.

This document provides an overview of 11 programming trends that are changing how developers work:
1. The Java Virtual Machine (JVM) is being used by many languages beyond just Java through cross-compilation, like Ruby, Scala, and Groovy.
2. Similarly, JavaScript is being used beyond just JavaScript through languages that cross-compile to JavaScript like Google Web Toolkit (GWT) and CoffeeScript.
3. There is a rise in "walled gardens" or tightly controlled development platforms like Apple's App Store and Facebook apps that limit developers' freedom.
4. Code is increasingly being developed as modules or snippets that integrate into frameworks rather than standalone programs, challenging traditional notions of ownership
Java was created by James Gosling and his team at Sun Microsystems in 1991. It was originally designed for television but later shifted focus to use on the Internet when released in 1996. Java applications are compiled to bytecode that can run on any Java Virtual Machine, making code portable across platforms. Key features of Java include its simplicity, object-oriented design, security, and ability to write code once and run it anywhere. It differs from C/C++ in its removal of pointers and inclusion of automatic memory management through garbage collection.

Javascript has fundamental flaws that cannot be fixed merely by evolving the language. Building delightful applications on the web today is far too difficult. The cyclone of innovation is increasingly moving off the web onto iOS and other closed platforms. Javascript has been a part of the web platform since its infancy, but the web has begun to outgrown it. Complex web apps--the kind that Google specializes in--are struggling against the platform and working with a language that cannot be tooled and has inherent performance problems. Even smaller-scale apps written by hobbyist developers have to navigate a confusing labyrinth of frameworks and incompatible design patterns. Javascript as it exists today will likely not be a viable solution long-term. Something must change.

3. Introduction
So, What is a programming language?
A programming language is a formal constructed language
designed to communicate instructions to a machine, particularly
a computer. Programming languages can be used to create
programs to control the behavior of a machine or to express
algorithms.
5. The green project
Sun Microsystems decided to develop special software that
could be used to manipulate consumer electronic devices.
A team of Sun Microsystems
programmers headed by James
Gosling was formed to undertake
this task.
6. Team Gathering
Staffed at 13 people, they began work in
a small office on Sand Hill Road in Menlo
Park, California.
7. The reason for Java
They take apart many electronic devices, like cable TV set-
top boxes and remote controls to find a way for the
appliances to talk to each other. They discover that the
consumer electronic devices like VCRs and settop boxes
all have different CPUs and limited memory.
8. The reason for Java
No longer was its aim to create a new language far
superior to the present ones, but it aimed to target the
language to devices(Embedded System) other than the
computer.
9. The Solution
● Brain storming of the team, all participated.
So the first outcome was (C++ ++ --).
● It renamed to Oak.
● the first demo 1991.
10. The failure
● Regarding the good solution but this technology did not
take off.
● March 15, 1993, the development team, now
incorporated as FirstPerson.
● FP shifted focus to to the settop box OS market
because of Time Warner.
11. Surviving
● April, 1993, NCSA Mosaic 1.0, the first graphical browser for the Internet, is
released.
● The focus of the team, now diverted towards where they thought the "next-wave" of
computing would be — the internet.
● The team then divulged into the realms of creating the same embeddable
technology to be used in the web browser space calling it an
applet — a small application.
12. The success
The team created a list of features tackling the C++ problems. In their opinion,
the project should:
● Be simple and gather tested fundamentals and features from the earlier languages in it.
● Have standard sets of APIs with basic and advanced features bundled with the language,
● Get rid of concepts requiring direct manipulation of hardware (in this case,
● Be platform independent and may written for every platform once (giving birth to the WORA
idiom),
● Be able to manipulate network programming out-of-the-box,
● Be embeddable in web browsers, and ...
● Have the ability for a single program to multi-task and do multiple things at the same time.
13. Show time
May 23, 1995 Sun formally announces Java and HotJava
at SunWorld '95.
