There are several possible reasons for creating a language, some of which are not immediately obvious. I would like to present them together with an approach to make a language for the Java Virtual Machine(JVM) reusing existing tools as much as possible. In this way we will reduce the development effort and provide a toolchain familiar to the user, making it easier to adopt our new programming language.

In this article, the first of the series, I will present an overview of the strategy and various tools involved in creating our very own programming language for the JVM. in future articles, we will dive into the implementation details.

In this post we will go over the current state of ES6 modularity, by learning how to use the Jspm package manager and its associated SystemJs module loader (the sample code is available here). We will go through the following topics:

• Using ES6 modules today
• Why is modularity important in Javascript
• The Jspm package manager and how to use it today
• creating a ready to use bundle with Jspm
• The SystemJs module loader
• Jspm vs Bower
• Jspm vs npm
• Conclusions

In a traditional multi-tiered architecture like the one shown in the picture below a server-side web tier deals with authenticating the user by calling out to a relational database or an LDAP server. An HTTP session is then created containing the required authentication and user details. The security context is propagated between the tiers within the application server so there’s no need to re-authenticate the user.

Thousands of sites are built every day with The Twitter Bootstrap Framework. This is the most popular HTML, CSS and JavaScript responsive framework. Every developer and designer should know or learn how to use it.

If you have never used Bootstrap before, you are probably missing out. Why?

Bootstrap saves you a lot of time – The framework includes predefined CSS classes, styled HTML components and configured Javascript plugins ready to use, to help developers design pages better and faster.

Well, I’ve recently gone to the “silver” side and acquired a MacBook Pro to use it for development when I am not at my PC. By development I mean here mainly Java + Javascript development. So I’ve written this post to remember what I had to install/configure to achieve this goal.

I need to mention that until now I’ve been a user of Windows (XP/7) and Linux (Ubuntu/Mint/Cent OS) operation systems.

At the time of this writing MacBook Pro runs on OS X Yosemite Version 10.10.5. The new version El Capitan was available, but I didn’t do the upgrade first because it had to many bad reviews…
