This document summarizes the evolution of the Java programming language and platform. It discusses how Java started as a programming language in the 1990s and has since evolved into a popular platform used across desktop, mobile, and enterprise applications. Key points covered include Java's object-oriented design, how it improved productivity through features like automatic memory management, and how the platform has expanded through the Java Community Process and inclusion of dynamic JVM languages. The document argues that while Java the language may not be the best, the Java platform provides a strong, modular foundation for application development.

Computers are connected in a network to exchange information or resources with each other. Two or more computer are connected through network media called computer media.
There are a number of network devices or media that are involved to form computer network.
Computer loaded with Linux Operation System can also be a part of network whether it is a small or large network by multitasking and multi user natures.
Maintaining of system and network up and running is a task of System / Network Administrator’s job. In this article we are going to review frequently used network configuration and troubleshoot commands in Linux.
The components of an operating system all exist in order to make the different parts of a computer work together. All user software needs to go through the operating system in order to use any of the hardware, whether it be as simple as a mouse or keyboard or as complex as an Internet component.

Java: Rumours of my demise are greatly exaggeratedSteve Dalton
The Java Platform has had a rocky year with the acquisition of Sun by Oracle and unfortunate bickering about language release schedules and licensing emerging. Despite all of this the community is strong and extremely innovative use of the platform continues at a great pace.
This talk will cover some of the JVM options available to developers on the Linux platform along with a introduction to the myriad of alternative languages available, some you will have definitely heard of and some not.
I will also give an executive summary of the political side of Java and where I believe the platform is heading.
JavaScript language plays a very important role in Web 2.0 application development. JavaScript has its own characteristics different than object-oriented languages and it's not easy for developers to understand.
This presentation covers major advanced topics in JavaScript languages, including prototype chain, identifier resolving, "this" keyword, "new" operator, execution context and scope chain and closure. Besides that, it also covers best practices when using JavaScript.
GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
