Ethereum and Solidity: The Complete Developer’s Guide

Ethereum and Solidity: The Complete Developer’s Guide

Use Ethereum, Solidity, and Smart Contracts to build production-ready apps based on the blockchain

Ethereum and Solidity: The Complete Developer’s Guide
English | MP4 | AVC 1280×720 | AAC 48KHz 2ch | 24 Hours | 3.62 GB
eLearning | Skill level: All Levels


  • Basic Knowledge of Javascript and NPM
  • A Mac, PC, or Linux Machine


Smart Contracts? They’re here.  The Ethereum Blockchain?  Covered.  Solidity?  Yep!

There can be no understating it: Ethereum and Blockchain technology is the most disruptive force in years.  Companies cannot hire developers who understand blockchain technologies fast enough, but there are a tiny number of resources published to help you truly understand what blockchains are used for, let alone build apps with them.  That’s the purpose of this course: to be the best resource online for learning about Ethereum, blockchains, and how to build apps with this new technology.

The development community is still figuring out the best way to use Ethereum in the creation of new and exciting apps.  I spent a tremendous amount of time to research and create best practice for interfacing with Ethereum from Javascript.  I can’t overstate it enough; this course will show you the best and most easily repeatable patterns for creating production-ready apps with Ethereum.

What tools and libraries are used?

The Ethereum tech ecosystem is in constant change.  Don’t be fooled by other courses that mention how you’ll learn a dozen different libraries!  Every library that you’ll use with Ethereum breaks and is deprecated on a near-weekly basis!  Instead, this course will teach you how to assemble your own boilerplate package to develop, compile, and test Smart Contracts.  By learning the core technologies, you’ll be prepared to adjust to Ethereum no matter how the ecosystem changes.

What is Ethereum?

Ethereum is a cryptocurrency much like Bitcoin, and it has been heralded as Bitcoins successor.  Whereas Bitcoin currently has issues scaling with an increasing backlog of transactions, Ethereum is poised to surpass Bitcoin in performance, popularity, and value.  Ethereum was created to help developers like you create applications focused around transferring money or value from one party to another.

What is Solidity?

Solidity is a programming language for writing Smart Contracts.  Essentially, think of it as a way to control a bank account with code.  With Solidity, we can write applications that simulate a crowd funding campaign, a lottery, a loan, or any other type of financial instrument.  Don’t be intimidated by learning ‘another’ programming language; Solidity is known to be quite similar to Javascript and exceptionally easy to pick up for anyone who has previous JS experience.  This course will give you all the tools you need to master Solidity.

Who this course is for:
  • Programmers looking to leverage blockchain technology for advanced apps
  • Engineers who want to understand Ethereum and how to build apps with it

PHP for Beginners
English | MP4 | AVC 1280×720 | AAC 44KHz 2ch | 14 Hours | 1.50 GB
eLearning | Skill level: All Levels


  • Access to a computer running Windows, Mac OS X or Linux.


Are you wanting to get into Web development, but are not sure where to start?

So maybe you tried out some PHP and MySQL tutorials on Youtube, but found them too hard or outdated, and feel that you need a more comprehensive introduction.

Maybe you want to learn how to write PHP the right way.  Secure code, OOP ready, and maximising re-usability as well as finding out about PHP programming standards to adopt and adhere too?

Perhaps your boss or client threw you in the deep end with a PHP and MySQL project, and you need to get up to speed with PHP, fast.

Whatever the reason, this course is for you.

This course is going to teach you how to create web applications using PHP and MySQL.  Specifically, you will learn PHP and then create you own content management system (CMS) from scratch.

Why PHP?

PHP is the most popular website programming language in the world.  The combination of PHP and MySQL is used extensively to create web applications, and developers with these key skills are in high demand.  This course is going to teach you how to create web applications in PHP using the MySQL database.

What will you learn in this course?

You will learn  how to create a dynamic website using the most popular website programming language in the world, PHP.

Dave Hollingworth, your instructor will teach you the PHP programming language, and take you through the steps to build a working CMS in PHP and MySQL from scratch.

Along the way, you will learn how to secure your code, how to write reusable, more maintainable code using programming standards, and how to structure your code using object-oriented programming techniques.

Dave will teach you the theory and then put the theory into practice when building the CMS.

You will also learn how to style your site using Bootstrap, how to integrate third-party code into your site, how to store data in a relational database and use this from PHP code, and more.

The course is very thorough, and goes through everything from installing a web server on your own computer, and editor to writing the code to create your web app.  Towards the end of the course you will even learn how to upload the code and make your code live on the internet (very useful if you already have your own Hosting account).  This is not necessary to complete the course though.

In summary, the course will teach you the core skills you need to know to become a productive PHP programmer.

Why this course?

Firstly, Dave has been creating web applications since 1999, when he created his first web application for a major insurance company.  In addition he has been teaching IT for many years.

As a result, you will be learning the best practices from an experienced developer.

Dave will teach you the theory but then show how to put those techniques into practice.  You will start building a CMS application from early on in the course and new techniques and theory are introduced as and when they’re needed to build the next part of the CMS.

New code is introduced one word or one line at a time, so you will never get bogged down or overwhelmed.

You will also learn real-world developer skills such as referring to and getting the most out of the documentation. This is an essential skill for developers to learn.

After completing this course, you will have the necessary skills to be able to create your own web applications with PHP and MySQL.

The sooner you sign up for this course, the sooner you will have the skills and knowledge you need to increase your job or consulting opportunities.    PHP developers are in high demand!

Your new job or consulting opportunity awaits!

 Why would you take this course?

Hi! My name is Mihai. I’ve been a Network Engineer since 2008, having the privilege of working for 3 major corporations and configuring, maintaining and testing multi-vendor network environments. At the same time, I managed to obtain several well-known certifications, such as CCNA, CCDA, JNCIA and CCNP, which complemented the skills I was getting from my job and increased the number of job offers I was receiving to my LinkedIn inbox.

But the thing that simply jumpstarted my career was learning the Python programming languageand implementing it in some of my daily tasks and processes. I’ve been a self-taught guy for most of my adult life and, since I lacked the time to read endless, boring programming books, I chose to learn by watching video tutorials and “getting my hands dirty” with code. Unfortunately, at that time I was unable to find a complete, coherent programming course for network engineers, so I had to put together various pieces of information scattered across Google and YouTube.

Almost two years later, after I had the chance to practice my new Python skills intensively, performing various tasks on network devices and automating hundreds of network tests, I decided to create this course for you – the network professional who knows that getting a certification just isn’t enough anymore in today’s job market. The ability to write scripts and automate certain tasks is one of the primary skills that the big employers are looking for.

This course simply enables you to save time and efforts whilst acquiring these in-demand skills and upgrading your career.

Join thousands of successful network engineers who have decided to learn Python using this 100% hands-on course!

Without further ado, I’ll let you read more about the contents of the course down below and I’ll hopefully see you in the first lecture.

 What others have to say about this course?

“I have been programming since 1978 and wanted to learn python. I have had no java or OOP experience, and I tried several ‘paper’ tutorials but got little out of them. The first part of this course is a steady walk through the Python language at just the right speed. The instructor seems to touch all the basis in a logical and methodical way while providing examples and explanations. I can only conclude the instructor is a professional educator who spent considerable time structuring and organizing the course. The result is evident. THIS IS A GREAT WAY TO LEARN PYTHON!” by Larry Laswell

“I’ve tried learning from the books & multiple videos – most were too basic to make a practical app. Some books were too thick and made me sleep. But still none of the materials had the perfect balance like this course where all the basics were covered, instructions were concise, and Mihai walks you through how to create 7 practical apps step by step. I’ve also tried reading some advanced python book which didn’t make sense because it was too advanced. Let me tell you, this is hands down “that course that takes you up to beyond the basics” to bridge you to the advance topics. Right now I’m hitting the advanced topics and it finally makes sense…” by Joon Park

“Usually I’m not doing courses review but this time I will make an exception. During time I took a lot of trainings but very few provided by Udemy proved as having the right approach in teaching the audience. I will mark this one as being one of my personal top three best trainings as content’s quality, technical explanations, and additional learning materials perspective. Long story short this course is a very simple, straight forward way of learning Python for managing IT networks.” by Johnny Stanescu

“This is a great course for network engineers who would like to start automating their tasks. Geared towards beginners, this course teaches the fundamentals of programming and applying those concepts to networking. There is a lot of fluff about python on the internet, however the instructor managed to put together the necessary information to start automating the network. A working knowledge of TCP/IP is needed to get the most out of this course. Should you understand every lecture, you will be ready to start writing your own scripts according to your needs. In particular, I loved the use of scapy, an amazing tool which should be in the arsenal of anyone working with TCP/IP.” by Costin-Alin Neacsu

“I’ve seen the blueprint and some demo videos and I was convinced right away. Without a doubt, it’s one of the best trainings a network engineer can have. It gives you actual valuable and marketable skills that you can use in your daily job. Mihai explains the topics really well, with practical examples making it a fun way to learn. Highly recommended.” by Vlad Vlaicu

Are you embarking on creating an API for your website or mobile app? If so, just striking forward with your API could be a mistake. In this course, you will learn how to design an API to meet the demands of your customers.

Too many APIs are just built on an as-needed basis. In this course, Designing RESTful Web APIs, you will design your API to meet your needs before you embark on implementing the service. First, you will explore the design philosophies of creating an API on top of REST without the dogma. Next, you will discover how to design APIs to take URIs, verbs, message bodies, versioning and security into account. Finally, you will examine how creating an API can stand up to the test of time instead of extending your proof of concept into a supported API you can’t get rid of. By the end of this course, you will have complete understanding and knowledge to produce useful APIs for your project.

The Complete React Web Developer Course (2nd Edition)


The Complete React Web Developer Course (2nd Edition)

Learn how to build and launch React web applications using React, Redux, Webpack, React-Router, and more!


React Web Developer


  • A computer on which you can install software (Windows, MacOS, or Linux)
  • An understanding of core JavaScript (functions, objects, arrays, callback functions)

This course was just updated to support React v16 (React Fiber)!

Have you tried to learn React before?

It’s easy to go down the rabbit hole of libraries and tools only to come out of it not knowing how to build and launch a real-world React application. You get things configured, but you’re not sure how the libraries fit together (or if you’re even using the right one).

Sound familiar?

I built this course to show you how you can build and launch real-world React web applications.

The Complete React Web Developer Course 2 starts with the fundamentals and covers everything you’ll need to build and launch React web apps.

You’ll see what it takes to build and launch a React app, from the first line of code to the final production deployment.

This course was designed around one goal: turning you into a professional React developer capable of developing, testing, and deploying real-world production applications.

You’ll learn React by doing, not watching.

From the first videos you’ll be building out each project as well as completing programming challenges I’ve designed to test and reinforce what you’ve learned.

Throughout the course you’ll build two React web apps:

  1. The first app, a decision-making app called Indecision, is our starter application. You’ll learn the fundamentals of React while seeing exactly what it takes to get a React app up and running.
  2. The second app, an expense manager called Expensify, has all the features you’d expect from a real application. You’ll set up authentication, user accounts, routing, testing, form validation, database storage, and more.

Stay up-to-date in an ever changing world.

The world of React changes fast, and that’s why I’m always working to keep this course as up-to-date as possible. You can jump in knowing you’re getting access to hot-off-the-press features.

Everything you need comes in one easy-to-use package.

There’s no need to worry if you’re learning the right skills to land that React job or launch that React app. I’ve mapped out everything you need to know in an interactive easy-to-follow package designed to get you up and running in a couple of weeks.

There’s no better time to learn React.

React’s not going anywhere. Companies like Facebook, Walmart, Uber, Airbnb, and Netflix are all using React in production right now.

They’ve also made heavy investments in the React ecosystem, creating new libraries and tools that speed up and simplify React development. From the biggest to the smallest, everyone’s using React and new jobs are popping up every day.

Get access to fast support if you get stuck.

There’s nothing worse than getting stuck ten hours into a course and not getting the help you need to continue. Getting stuck is part of the learning process. That’s why I’m here to answer every single question.

I’ll work with you to get you unstuck and back on track. It’s one of the reasons students love taking my courses:

“This is the absolute best course I’ve taken on udemy. Andrew is amazing at explaining things concisely, and the flow of the course is perfect. He doesn’t skip over anything and he doesn’t over-explain anything. On top of all that, he responds to questions so quickly that you won’t be stuck at any point.” – Tanya Gamarian

“The lessons are of high quality and even more important, he actually takes time to answer your questions!” – Thomas Vercamer

“The instructor does an excellent job in explaining how to build React Apps. He also responds quickly to any questions that are asked.” – Matt Willy

I guarantee that this is the most up-to-date and engaging React course available, and it comes with a Udemy 30-day money-back guarantee.

Over eighteen sections you’ll learn:

  1. React
  2. Redux
  3. React-Router
  4. Webpack
  5. Babel
  6. Testing with Jest
  7. Enzyme
  8. App Debugging
  9. App Deployment
  10. Firebase
  11. Authentication
  12. Git/GitHub
  13. ES6/ES7
  14. And many more tools

I can’t wait to see you on the inside!

– Andrew

Who is the target audience?
  • Anyone looking to launch their own React applications, switch careers, or freelance as a React developer
