To put it simply, esProc SPL is an intriguing programming language and a powerful data computing middleware, and can also work as a high-efficiency data warehouse: find more in Understand SPL in three aspects.

Different from the text-based programming language, SPL writes code in gridlines: find more in A programming language coding in a grid; as a data computing engine, SPL can generate high efficiency at much lower cost: esProc SPL, a data analysis engine reducing application cost by N times.

esProc SPL is a JVM-based data computing class library: SPL: The Open-source Java Library to Process Structured Data. It has much more and better functionalities than the other data processing languages based on JVM (Such as Kotlin and Scala): Competition of data processing languages on JVM: Kotlin, Scala and SPL. It can perform SQL-style computations without databases: Open-source SPL that can…

The Public APIs repository is manually curated by community members like you and folks working at APILayer. It includes an extensive list of public APIs from many domains that you can use for your own products. Consider it a treasure trove of APIs well-managed by the community over the years.

APILayer is the fastest way to integrate APIs into any product. There are a lot of APIs available at APILayer Marketplace.

API	Description	Call this API
IP Stack	Locate and Identify Website Visitors by IP Address
Marketstack	Free, easy-to-use REST API interface delivering worldwide stock market data in JSON format
Weatherstack	Retrieve instant, accurate weather information for any location in the world in lightweight JSON format

Fixer	Fixer is a simple and lightweight API for current and historical foreign exchange (forex) rates.

This repository ("Code - OSS") is where we (Microsoft) develop the Visual Studio Code product together with the community. Not only do we work on code and issues here, we also publish our roadmap, monthly iteration plans, and our endgame plans. This source code is available to everyone under the standard MIT license.

Visual Studio Code is a distribution of the Code - OSS repository with Microsoft-specific customizations released under a traditional Microsoft product license.

Visual Studio Code combines the simplicity of a code editor with what developers need for their core edit-build-debug cycle. It provides comprehensive code editing, navigation, and understanding support along with lightweight debugging, a rich extensibility model, and lightweight integration with existing tools.

Visual Studio Code is updated monthly with new features and bug fixes…

React is a JavaScript library for building user interfaces.

• Declarative: React makes it painless to create interactive UIs. Design simple views for each state in your application, and React will efficiently update and render just the right components when your data changes. Declarative views make your code more predictable, simpler to understand, and easier to debug.
• Component-Based: Build encapsulated components that manage their own state, then compose them to make complex UIs. Since component logic is written in JavaScript instead of templates, you can easily pass rich data through your app and keep the state out of the DOM.
• Learn Once, Write Anywhere: We don't make assumptions about the rest of your technology stack, so you can develop new features in React without rewriting existing code. React can also render on the server using Node and power mobile apps using React Native.

I originally created this as a short to-do list of study topics for becoming a software engineer but it grew to the large list you see today. After going through this study plan, I got hired as a Software Development Engineer at Amazon You probably won't have to study as much as I did. Anyway, everything you need is here.

I studied about 8-12 hours a day, for several months. This is my story: Why I studied full-time for 8 months for a Google interview

Please Note: You won't need to study as much as I did. I wasted a lot of time on things I didn't need to know. More info about that is below. I'll help you get there without wasting your precious time.

The items listed here will prepare you well for a technical interview at just about any software company including the…

An opinionated guide on how to become a professional Web/Mobile App Developer.

🔹 Developer Handbook 2023 🔹 was created to cover the most common technical questions and requirements appearing prior to job interviews, during onboarding or personal goals / career planning at our company - Apptension. We also like to call it a Technical Documentation of our company.

It contains a lot of subjective technical groups, opinionated technologies, vetted requirements and best practices we gathered for Web & Mobile Developers that we believe to be useful in 2023.

Also, check out our SaaS Boilerplate, which is an example of our experience and a real-life application of many of the technologies and designs described in the Handbook.

Enjoy reading! 🙇

• This document originated from a bunch of most commonly used links and learning resources I sent to every new web developer on our full-stack web development team.
• What I'm doing in this document now is trying to provide the complete view angle of modern web (app or page) development ruled by JavaScript, reflect technological advance and help developers to acquire APIs, libraries, tools, services, best practices and learning resource which are not outdated and most commonly used.
• I hope this document can help one developer to have more power to do much more and much better, just like a spellbook does in fantasy worlds.

Software engineering principles, from Robert C. Martin's book Clean Code, adapted for JavaScript. This is not a style guide. It's a guide to producing readable, reusable, and refactorable software in JavaScript.

Not every principle herein has to be strictly followed, and even fewer will be universally agreed upon. These are guidelines and nothing more, but they are ones codified over many years of collective experience by the authors of Clean Code.

Our craft of software engineering is just a bit over 50 years old, and we are still learning a lot. When software architecture is as old as architecture itself, maybe then we will have harder rules to follow. For now, let these guidelines serve as a touchstone by which to assess the quality of the JavaScript…

While most "todo" demos provide an excellent cursory glance at a framework's capabilities, they typically don't convey the knowledge & perspective required to actually build real applications with it.

RealWorld solves this by allowing you to choose any frontend (React, Angular, & more) and any backend (Node, Django, & more) and see how they power a real-world, beautifully designed full-stack app called Conduit.
