PJP-Introduction
Java is a computer programming language that allows programmers to express concepts and solve problems. The course teaches Java programming through practical implementation and hands-on projects to help students learn. It covers Java fundamentals, object-oriented programming, graphical user interfaces, databases, and other advanced topics. Students will build several small applications over the course to gain experience applying their Java skills.
Isotope
Isotope is a jQuery plugin that enables magical layouts by filtering and sorting DOM elements. While it may be possible to implement similar behaviors without Isotope using only JavaScript and jQuery, it would likely be more difficult. Knowing Isotope provides the benefit of being able to easily implement these interactions, even if the plugin was not widely known and did not have a distinctive name. General programming ability and skills with JavaScript and jQuery would remain valuable regardless of experience with any specific libraries or plugins.

Notice Me, Senpai! Get Discovered with Creative Technical Content
"Notice me, Senpai!" - well, in this case, Senpai = developers.
Developer acquisition and adoption don't go proportionally to the quality of your platform, APIs, dev tools etc. If developers out there have never heard of your products, you fail no matter how awesome your developer offerings are. You must be discovered first, and getting discovered is not so easy.
In this talk, Tomomi Imura will share her experiences at various companies, including large corporates to start-ups and how she created developer-centric contents and docs to drive the community and acquire new developers.
Visual Validation - The Missing Tip of the Automation Pyramid
The Test Automation Pyramid is not a new concept. The top of the pyramid is our UI / end-2-end functional tests - which should cover the breadth of the product.
What the functional tests cannot capture though, is the aspects of UX validations that can only be seen and in some cases, captured by the human eye. This is where the new buzzwords of AI & ML can truly help.
In this session, we will explore why Visual Validation is an important cog in the wheel of Test Automation and also different tools and techniques that can help achieve this. We will also see a demo of Applitools Eyes - and how it can be a good option to close this gap in automation!

Let’s say, you are searching certain frameworks, or APIs to satisfy your new project- what if you stumble on some awesome-sounding shiny website, but it comes with very poor documentations. Do you want to try it out, or keep searching something else? Or when you see a GitHub project with no README, how do you feel? I think this developer experience is one of big key factors for you to decide what technologies to use.
User-Experience (UX) focuses on understanding what users' need and value, and provide practical products or services. This human-computer interaction acts the same when the users are developers. The ideas of “Developer Experiences” is to establish a good relationship between developers and platform providers.
So, as a developer evangelist, what can we do to improve DX to get developers' interests?
In this talk, Tomomi Imura will talk about her experiences, and how I create developer-centric contents and docs to drive the community and acquired new developers and customers.
Full-Stack Development
A full-stack developer is someone who can take a project from conception to a finished product, handling both front-end and back-end development. They have a wide range of skills across the stack rather than deep expertise in one area. Full-stack developers are well-suited for small startups but may face more scaling challenges in larger companies with more specialized roles. The document discusses technologies used in full-stack development and tips for learning new skills like contributing to open source projects.
Architecture @ Appknox

Whay QA- engineers should know how to code
This document discusses why a QA engineer should learn to code. It provides several reasons why the author, a QA engineer, decided to learn programming including wanting to better understand what is happening in the code, becoming a true testing expert, and earning more money. The document then outlines a plan for learning to code starting with Python and provides recommendations on online courses and resources for getting started with programming.
Recipe of a rockstar developer
A developer must focus on delivering working software instead of just coding. To be a "rockstar developer", one must have strong knowledge in algorithms, object-oriented programming, design patterns, refactoring, source control, unit testing, and software development processes like Scrum. It is important to continuously learn new technologies, practices, and standards. When choosing a company, consider factors like their use of source control and continuous integration, availability of mentors, and work-life balance. Freelancing can hinder career growth; working with other experienced developers is most beneficial for improvement.
Js basics
John was learning how to code by watching courses and reading tutorials. However, he was not practicing what he learned and was just copying code without understanding how it worked. He became frustrated easily and lost motivation because he thought he would never know everything. To succeed, it is important to set clear learning goals, understand each new concept by typing the code, take notes, practice coding regularly through exercises and personal projects, and ask others for help.

Orthogonality: A Strategy for Reusable Code
This document discusses the concept of orthogonality in software design. It defines orthogonality as making features that minimally depend on each other, such as code, methods, classes, libraries, and more. The benefits of orthogonality include easier maintenance, reading, and reuse as changes to one part do not affect others. Techniques for achieving orthogonality include designing components as reusable "Lego bricks", minimizing state, favoring immutability, and separating concerns through clear APIs. The document provides examples of applying these principles in case studies of image processing, analytics and OCR libraries.

Clean code
This document summarizes key principles for writing clean code as outlined in the book "Clean Code" by Robert C. Martin. It discusses ideas like writing code that is easy to read and understand through use of meaningful names, small functions that do one thing well, and avoiding duplication. It also covers principles for object-oriented design like encapsulation, organization for change, and separation of concerns. Testing philosophies like test-driven development and ensuring tests are fast, independent, repeatable, self-validating, and timely are also emphasized. The overall message is that writing clean code requires attention to structure, naming, formatting and testing to produce software that is simple, well-organized and a pleasure to maintain.

Test Driven Development with Laravel
This document discusses test driven development (TDD) with Laravel. It begins with an introduction to the author and overview of TDD. The main benefits of TDD are described as code confidence, cleaner code, and fewer bugs. An example of building tests for a car wash management tool is provided to demonstrate the TDD cycle of red-green-refactor. Key points are made about what to test, including focusing on data transformations and keeping controllers skinny. Views are generally not tested, but using presenters allows views to be fully tested.

TDD - Cultivating a Beginner's Mind
The document discusses how test-driven development (TDD) can help software developers avoid design mistakes that stem from relying too heavily on past experience. It notes that experience can make developers vulnerable by leading them to automatically apply familiar patterns without considering if they are the best solution. TDD encourages an incremental "beginner's mind" approach where the simplest code is written to pass each test before refactoring, which helps developers introduce the right abstractions and avoid over-engineering. Refactoring is key to improving designs emerging from TDD. The document advocates practicing TDD and refactoring to cultivate humility and flexibility in design.
Java 9, JShell, and Modularity
Java 9 introduced several new features including JShell, modules, and services. JShell allows developers to test Java code interactively from the command line. Modules allow Java code to be modularized by defining explicit dependencies and encapsulating packages. Services allow modules to discover implementations of an interface at runtime through a service loader. The modularization of Java aims to improve maintainability, security, and performance of Java applications.
