Out there, you could have a chance to work on many other interesting projects, for different companies, knowing and learning from different like-minded mates. And whats more, you could change and move on diverse projects, surfing the waves of bleeding edge technologies from anywhere, and this time, “any” is for good. Remote positions are the right answer to be truly on the pathway to an plelo and ever-growing career. One thing is for sure: But how could you join the ranks of the top-notch web engineers like the web developers Group at Toptal?

Probably you already completed a degree wich difficulty was above the average, and you are, by far, playing a very specialized role, dealing with a plethora of iptab,es and solving complex tasks. You write commands on a console without hesitation and you know how to build and deliver stuff. Are you up for a leap? Because as a young Bilbo Baggins, maybe you prefer to stay in the same place, where you feel comfortable and secure, and where everything is just fine as it is.

This is a matter of will. In the first third of the book the Java programming principles are covered with many specific details of the language.

Then the attention is focused in the good programming practices that every single developer should master, despite the language is used: Actually the lack of technical disciplines makes the agile process to become just a simple business process without the ultimate goal: To become a good developer you should create maintainable, easy-to-read and clean code following good practices, and that is what Software Craftmanship is all about.

But it is also necessary to know which tools could make our software easier to be developed and maintained.

Anytime you are programming enterprise applications or any other kind of projects accessing iptablees you will be applying common patterns such as MVC, DAO and dependency injection tools.


There are frameworks for every language, but when it comes to Java, the indisputable leader after more than a decade is Spring. At its core, Spring is a dependency injection framework that provides support for any features an application may need, such as database access, web development, aspects, and it is capable of work with many other available frameworks like Hibernate.

For any developer willing to work with enterprise Java environment, Spring is a must, as well as other usual companions like Hibernate, and tools like Maven, Gradle, Git, etc. And whatsmore, all the technologies that have emerged over the last decade around the web, the noSQL databases and the like, are already available to be integrated with this framework.

According to this, we are preparing a book about Spring that hopefully will become a useful guide for modern JEE development.

We have experience as a developers and also as teachers and mentors of this peolo, with other works published around these particular area. That allows us to meet the requirements not olny for developers looking for thorough references but also for those who are new to iptablse software ecosystem.

This work will be long enough for those who need a first dive as well as deep enough for the already initiated that need updates on version 5 of Spring. Therefore the basic principles of dependency injection, aspects, data access, inversion of control, MVC projects and REST resources are covered throughout the book. In addition to that, a wide variety of areas will be exposed as Spring boot, different template engines, reactive spring, etc.

Always showing simple proof of concept projects to quickly understand the idea; so once you get the ball rolling we will show how to implement complex developments involving different elements of a JEE project.

This is a simple sample React App that shows the basic usage of this framework.

It generetas simple arythmetic problems. React is a JavaScript framework developed by Facebook to create user interfaces. The main advantage of React is that it manipulates the DOM faster than any other framework out there.


React is all the rage and it seems to be pe,lo serious competitor for Angular. This is the typical hello world sample. It uses two JavaScript libraries: It also uses Babela library that lets us to use advanced ES6 syntax that it translates to compatible JavaScript for any iptahles. In this post I will introduce Javascript objects, how to define them, how to add attributes and methods and how to access them. Maybe you have heard that Javascript is an object oriented language but that definition is not very precise, specially when comparing to other languages.

There are no classes! Anyway now we will dip our toes into the waters just a little psllo become familiar with the notation. Prototypes, inheritance and other advance stuff will come next. Posts The will to Act.

And at the same time, there are so many technologies emerging and continuously evolving that specialized roles are required in every corner: IoT, blockchain, machine learning, you name it. We can consider ourselves extra-lucky because we are able to choose and build a specific career in whatever area we like. Therefore it iptablss quite easy to find a job anytime, anywhere.

You get a job, you are part of a company, you have your place, your multiple screens and some extra goodies. There is also a hideous feeling growing in your guts: Incoming new Spring 5 book. List tables with size in I;tables. It generetas simple arythmetic problems The Apps has just a form where you can choose options like Student Name, difficulty, And then, React generates some random operators, each of them is a Component How was it made The App was iptaboes using Facebook’s tool, which takes care of project scaffolding npm install -g create-react-app.
