Edit and execute programming code online quick

Ever wish you could test a snippet of code? Online. Like now! Or focus on improving an algorithm in isolation. Or have a moment of clarity and need to write a piece of code lickety-split. Yesterday, I found this online tool to do just that. That’s good for me, as I don’t have to create a whole new project in IntelliJ IDEA or use the CLI tools.

CodePad supports several of the most used programming languages. Unfortunately, it doesn’t support Haskell, a language I’d like to tackle this year. But for Scala, it’s really good.

The tool itself is easy to use and the compiler quick enough. In my case, I was using it to optimise a piece of Scala code to submit for an online coding exercise.

How to become the best mad skills programmer

Learning to program in a new language can often be difficult. First, you have to learn the basics to code “Hello World”. Then comes the challenge of learning to use the advanced features. And finally, the challenge of using the language the way the creator had intended.

The challenge is finding exciting exercises and projects to tackle. Something big enough to sink your teeth in. Yet not so big that the challenge seems impossible. Continue reading “How to become the best mad skills programmer”

Why I decided to learn Scala

I find that anything worth learning should be done by jumping in head first. Then find something halfway challenging and go to it. Hence, this is how I went about learning Scala. I’ve recently learned to program in Groovy to develop Spock based unit tests. Groovy was the first JVM language I learned outside of Java. And being pleasantly surprised, I decided to try my hand at Scala.

Why I Chose Scala

My reasoning for wanting to learn Scala is to get into artificial intelligence without straying away from the JVM. I have played around with Python which I really liked. But embarking on Python would take me into a whole new ecosystem. And although I would love to get involved in Python and its data science tools, I think that long term Scala may be the better option. Continue reading “Why I decided to learn Scala”

Startup Project – Part 3 : Testing, Mocking and Learning

Untitled design (5)It’s amazingly interesting what you learn when you’re in the throws of unit testing code. It particular when you’ve written more code than you’ve written unit tests. Yeah, yeah, I know, unit tests should be written with the code as you go; TDD. But let’s face it sometimes you just need to get stuff done. Until you get to the point where you think that now’s a good time to unit test everything.

I spent the whole afternoon, up until 11:30pm writing unit tests. Refactoring some code to make some of it easy to mock. And other parts I rewrote simply because it’s the right thing to do for OOP’s sake. It’s fun. Not everyone likes to unit test, but I love it. It gives me that satisfaction that my code is well written. Especially that feeling you get when you know the architecture you designed is solid. And the libraries you’ve chosen haven’t failed you. Plus learning something new about Java 8. Continue reading “Startup Project – Part 3 : Testing, Mocking and Learning”

A Startup Project – The beginning

frameworkRecently, I started working on a startup project that I am motivated doing.  I had been looking for an idea ever since I can remember. But every idea I thought of always required a heavy upfront ramp-up. The only condition for this idea was that I would find frameworks that were easy to use. Yet would be easy to swap out at a later time. So I set out to search for what I needed to get started.

I did a lot of research into all sorts of frameworks and was impressed with what I was finding. I had already decided that I was going to develop my solution in Java with a MongoDB database. My only condition is that the frameworks and libraries had to be simple, focused and mature. Continue reading “A Startup Project – The beginning”
