Curso de Java #4: La historia completa de Java

Java's Origins and Development

This section delves into the history of Java, its creator James Gosling, and the development of the language at Sun Microsystems.

James Gosling and Green Project

• James Gosling, a computer science graduate who had worked at IBM, was involved in various projects before joining Sun Microsystems.

• In 1990, Sun Microsystems initiated the Green Project led by James Gosling to explore innovative uses of microprocessors beyond traditional computing.

• The Green Project team, fascinated by technology integration outside typical computing realms, conducted extensive research globally to gather ideas for their project.

Creation of Prototypes

• The team developed a business plan based on collected ideas from global companies outside the tech industry.

• A prototype named Start Seven was created using unconventional methods like "hammer engineering," repurposing electronics from various devices.

Evolution of Start Seven Prototype

This section discusses how the Start Seven prototype evolved and its potential as a remote control system for household electronics.

Evolution of Start Seven

• The Start Seven prototype was an experimental device resembling a portable machine with components sourced from diverse consumer electronics.

• Engineers repurposed connectors from Sony Walkmans and other devices to build the prototype.

Java Emergence from Green Project

This part explores how Java emerged from the Green Project's initial focus on remote control systems for home appliances.

Java's Development

• Java originated as a language influenced by C++, Simula, Pascal, Mesa, Lisp, and others due to evolving project requirements beyond networking and security capabilities.

Cosas Flojas y Cream Project 2

The transcript discusses the origins of naming the group "Cream Project 2" and the development of a language independent of platforms.

Naming Origins

• James was sitting at his desk, looking out the window at an oak tree while creating a folder in operating systems.

• The name "Java" was inspired by the oak tree outside, symbolizing independence from platforms.

Challenges with Processors and Language Development

The challenges faced with processors compared to other electronic components and how a language like Java could solve these issues.

Processor Challenges

• Unlike other components, changing processors required extensive reprogramming due to architecture differences.

• Cream Project members sought a language that could run on multiple platforms to ease processor transitions.

Evolution of Technology and Business Opportunities

How Java's adaptability across technologies led to business opportunities for Cream Project members.

Technological Evolution

• Java's adaptability facilitated technology evolution without extensive code rewriting.

• Initial research evolved into potential business ventures post-project completion.

Formation of First Person and Business Decisions

Transition from research to forming First Person within Sun Microsystems and making ethical business decisions.

Business Formation

• First Person formed as a subsidiary within Sun Microsystems after successful project completion.

• Ethical concerns led Cream Project members to part ways with cable companies for internet-focused endeavors.

Java's Positioning for Internet Applications

Strategic positioning of Java as an internet application tool due to its compatibility with evolving consumer needs.

Internet Application Focus

• Anticipation of widespread internet use drove Java's focus on creating applications for online usage.

Desarrollo de Java y su Impacto en la Web

This section discusses the development of Java and its impact on the web, including key events and challenges faced during its integration.

Java's Introduction to the Web

• In late 1994 or early 1995, John Gage introduced dynamic interactive objects on web pages using Java applets.

• Initial struggles with browser compatibility were overcome when a 3D molecule model demonstrated Java's capabilities effectively.

• The introduction of dynamic interactive content on web pages amazed audiences and paved the way for Java's formal announcement at Sun World '95.

Integration Challenges and Success

• Java faced integration challenges with browsers like Netscape and Microsoft but eventually became widely accepted in the web development community.

• Despite security emphasis, integrating with Internet Explorer on Windows 95 posed numerous reliability issues initially.

Oracle's Acquisition of Sun Microsystems and Legal Battles

This section delves into Oracle's acquisition of Sun Microsystems, legal disputes with Google over Java, and James Gosling's departure from Oracle.

Oracle-Sun Acquisition & Legal Disputes

• James Gosling left Oracle due to economic reasons and lack of respect in his role post-acquisition by Oracle.

• Legal battles between Oracle and Google over Java code usage in Android led to intense negotiations regarding licensing agreements.

James Gosling: From Oracle to Google

This part covers James Gosling's transition from Oracle to Google amidst legal disputes involving Java code usage.

Transition to Google

Desarrollo de Liquid Robotics y Contratación de James Gosling

This section discusses the development of Liquid Robotics, its focus on marine unmanned vehicles for data collection, and the hiring of James Gosling by the company.

Liquid Robotics Development

• Liquid Robotics was co-founded by an intimate friend of James Gosling from their time at Sun Microsystems working on Java 2 platform development.

• The company specializes in unmanned marine vehicles that collect vast amounts of ocean data transferred to a cloud database via satellite.

• Wave Gliders are small vessels collecting sensor data, communicating through satellites and mobile networks, utilizing solar and wave energy.

Hiring of James Gosling

• In late 2016, Liquid Robotics was acquired by Boeing. Following this acquisition, James Gosling left to work at Amazon Web Services.

James Gosling's Role at Amazon Web Services

This section delves into James Gosling's role at Amazon Web Services (AWS), particularly his involvement in the Amazon Corretto project related to Java technology.

Role at AWS

• James joined AWS as a Distinguished Engineer focusing on a Java-related project called Amazon Corretto, aimed at creating scalable and secure applications compatible with Java standards.

Success and Impact of Java Programming Language

This part highlights the success and widespread use of the Java programming language due to its lightweight execution environment and independence across various platforms.

Impact of Java

• Java is renowned for its success not only in web pages but also in video games, desktop applications, and mobile devices.

Java's Growth and Influence

The final segment emphasizes the extensive adoption of Java with over 7 million developers worldwide using it across more than 5 billion devices.
