One of my main concern when I considered the migration from Wordpress to Jekyll was how would I be able to handle multiple authors, because this plays an important role in the website supporting our Coding Friend Program. Fear no more, I have found a satisfactory way to handle multiple authors with Jekyll1 and in this short post I list the main points concerning that.

Not long time ago I have rediscovered an old friend - Bash1 Alias2. We got acquainted at the beginning of my computer science studies, when I visited a course held by Cisco, “Linux Essentials” or something similar, where the trainer mentioned at one point what were aliases and how handy they could be. Well 12 years later, and I still had not got that, until recently, when a flash of illumination struck me and since then I’ve been using them extensively in my everyday developer life. In this post I will present a short introduction to aliases and after that my way of using them.

In this post, I will give my two cents on migrating a programming blog from Wordpress1 to Jekyll2, namely I will list and detail the main steps I took for migrating Codingpedia.org.

Why?

Well, there were pains - I was experiencing performance issues (caused mainly by memory shortages on a 4GB machine) with the virtual private server from GoDaddy, where I used to host both Podcastpedia.org and Codingpedia.org. Codingpedia was developed initially with Wordpress1, which I still think is a great tool, if you want to quickly start a blog and don’t have programming experience, but it kinda requires a LAMP2 stack, which it’s kinda performance killer from a number of visitors forward. Of course you can always add more hardware to support the website, but that has a limit too. Limited was also the budget I was ready to spend on hosting, by today’s standards.

In a previous post, I’ve used Server Sent Events to create a monitoring dashboard. SSE are a one way messaging format form server to clients in contrast to Web Sockets where communication is bidirectional. In this post, I’ll use Web sockets to create a tiny chat server using Tyrus, the reference implementation of the Java API for WebSocket (JSR 356). A great introduction to this API can be found on Oracle Network here.

In order to keep the tutorial simple, the server and clients will be command line apps, no GUIs here, it is a serious blog :smile: So let’s get started!

I think it would be fair to state that we, as software developers, are always looking for the ways to write less code which does more stuff, automagically or not. With this regards, Spring Boot project, proud member of the Spring portfolio, disrupted the traditional approaches, dramatically speeding up and simplifying Spring-based applications development.

There is a lot to be said about Spring Boot, intrinsic details of how it works and its seamless integration with most if not all Spring projects. But its capabilities go far beyond that, supporting first-class integration with popular Java frameworks.

In this post we are going to take a look at how we can use Spring Boot in conjunction with Apache CXF project for a rapid REST(ful) web services development. As we are going to see very soon, Spring Boot takes care of quite a lot of boilerplate, letting us to concentrate on the parts of the application which do have real value. Hopefully, at the end of this post the benefits of adopting Spring Boot for your projects become apparent.

With that, let us get started by developing a simple people management REST(ful) web service, wrapped up into familiar PeopleRestService JAX-RS resource:
