I recently migrated my blog from Wordpress to GitHub Pages. Being the first post on this new platform it seems fitting that I write about the migration experience. If you are not familiar with GitHub pages you can go to that previous link and it will give you a nice overview of what it is and what you can do with it. The short version? It’s a free hosting for your site which is linked to your GitHub account. This means that when you push your code to your repo, your site is magically updated. This is something really cool and convenient.

In this post I’ll talk about Archaius, a pretty cool and easy to use Configuration Management tool from Netflix.

Following the topic of the last post, I will discuss another problem that can be solved efficiently using dynamic programming. Unlike the Fibonacci sequence that we saw on the introduction post, the problem that I present here is a bit more tricky to solve (which also makes it more interesting).

On this post I wanted to talk about Dynamic Programming. If you ever took an algorithms university course then you have probably heard about it. If you haven’t, here’s a good chance to learn something extremely useful, easy and intuitive (at least when you understand it properly).

I feel like I should start this post saying that I absolutely love git. If you’ve never heard of it, is a source control system like CVS or Subversion but, unlike those two, is a distributed version control system. I’m not going to get into much details about the history and capabilities of git but if you’re curious about it you can go to http://git-scm.com/book which is an amazing resource with everything from intro to advanced concepts.

I’ve previously talked a little bit about the Builder Pattern, a useful pattern to instantiate classes with several (possibly optional) attributes that results in easier to read, write and maintain client code, among other benefits. Today, I’m going to continue exploring object creation techniques but this time for a more general case.

In my first post I talked a little bit about the builder pattern and I mentioned a really powerful but yet overlooked concept: immutability. What is an immutable class? It’s simply a class whose instances can’t be modified. Every value for the class’ attributes is set on their declaration or in its constructor and they keep those values for the rest of the object’s life-cycle.

So, this is my first post (and my first blog for that matter). I can’t remember exactly where I read this (although I’m almost sure it was on Practices of an Agile Developer), but writing in a blog is supposed to help you get your thoughts together. Concretely, by taking the time to explain what you know, you get a better understanding of it yourself.
