The definitive guide to start with ClojureScript

Yesterday, while my working machine was crunching tons of numbers, graphs and maps to produce some (hopefully) meaningful data for a research work, I was looking for a simple guide to build a simple web page with ClojureScript. Unfortunately, I was not able to find something that was at the same time straightforward, simple, minimal and explained! So, I decided to write something by myself to avoid my pain to some future young clojurist.

The main problem with the guides I’ve found online were:

  1. They didn’t use Leiningen or any other build system. Now, this can also be good, but Leiningen is, in practice, a standard for Clojure developer, so I’d like to learn how to setup a project as soon as possible.
  2. They are outdated.
  3. They are not well explained. For sake of simplicity, they assume a lot of things. But I want to know what I’m writing!
  4. They are not simple. I don’t want to write a full featured web application with a lot of dependencies and plugins! I want an hello world!

So, I hope to cover all this points. Let’s start!

My peek on Atom

People who know me already know: I’m a tool maniac. I can spend hours searching for the perfect configuration of keys, plugins, colors, themes, debugging tools and so on, and unfortunately this is how I waste a lot of time every now and then. Text editors and IDE are one of these big tools that I cannot stop searching for the perfect one. The real problem, though, is that I cannot find satisfaction for more than a month on a particular editor, so, during my life as a coder I used with a certain degree of experience tons of editors such as Vim, Emacs, Sublime Text, GEdit and much more. Honestly! Look at this! If  I had spent less time on tweaking my editors and more on coding, now I would have more side projects completed for sure. Anyway…

I have a certain envy for those developers that are able to stick on, for instance, Vim for more than 20 years. They are happy and enthusiastic of their editor! Lucky them! But I’m not in this way. Maybe I find the exploration more rewarding. I don’t know.

So, coming back to the topic, when I used Linux I was happy too and my favourite editor was by far Vim. Yes, the learning curve is steep as hell but this thing has never scared me (I try to learn too many newborn and cryptic programming languages to be scared by a text editor, complex or not that may be. Then, a couple of years ago, I moved back to Windows and I started to work on bigger project. For some reason, my pleasure and muscle memory in using Vim began to disappear.

Now, there is a long story made of IDE and text editors but I don’t want to spend too much time talking about my evolution (or devolution, your call) in the world of programming editors. The real goal of this article is to explain why, for now, I’m happily landed on Atom, the text editor mad in GitHub.

Global Game Jam 2015 Postmortem

First of all, some time ago I stated that I would like to start writing more. Unfortunately, a combination of personal issues, flu and other psychological breaks did not allow me to respect this promise. But I’ll be back soon. I swear.

Second, it is now time to talk about the game we developed for the Global Game Jam 2015 (and obviously valid as a January entry for my One Game A Month challenge!) I’m very happy with this game also if it is not a real “game” because (little spoiler) it is an online game who require a big amount of users to be interesting. I’ll never have so many users connected at the same time, so it is useless in practice. The good thing is that it was a big technical challenge and to be able to complete everything in less than 30 hours was really exciting. But first things first.

The most promising languages of 2015 – Part 2

UPDATE: There is a new version of this article for 2016!

In the the previous post we have seen what are the general trends of the previous year with regard to the fascinating world of programming languages. To summarize, we can say the there are two strong trends: 1) more functional-inspired elements in programming languages 2) more statically strong typed languages that can be compiled in machine code.

Now, in the current article, I want to list all the languages which have attracted interests in the last years and that represent the implementation of these trends. Obviously, as I said in the previous article, these are not languages on which to bet their careers: these are new trendy languages but the real world does not work on “trends”, but on software, oil, commerce, health care and an hundred of categories in which the actual programming languages are doing great with an huge amount of per-existing codebase.

However, it is nice to explore the “future”, so, let’s take a look.
