Code review has become one of the most important (and used) techniques when it comes to code quality. The code review process may have very different workflows and subtleties, but it is often driven around the following steps: The developer responsible by the code (a new feature, a bug fix, a refactor, etc) sends his changes to other colleagues (in git it is called a patch, that can be transformed into a pull request, merge request, or any other name your Git repository hosting service calls ...| Spaghetti and Hammers - Articles
This month Slack announced to have raised $200M on its most recent financing. At the same time I started to turn off Slack during working hours. One chat to rule them all Slack (just as Hipchat, and many other alternatives) are messaging apps for teams. If you are on a still small startup (< 5 guys) maybe you don’t have anything similar yet, but as you start to grow, you will fell the need for it. And as soon as you notice, Slack will be one of the most important tools you have. Besides com...| Spaghetti and Hammers - Articles
Last week GitHub released another new feature: GPG signature verification. While it may seem something new, Git already supports signing commits and tags with GPG . Still, GitHub turned easier to verify if the commit is signed by the author, introducing a badge next to the commit UUID. How to sign my own commits If you want GitHub to display your verified commits there are a couple of steps required. GitHub provides a very good explanation on that. Assuming you don’t have a GPG key yet, you...| Spaghetti and Hammers - Articles
Following up my previous post on mapping json objects to Scala models, it is time to present some more advanced use cases.

Git has become one of the most essential tools for every developer. While most developers trust in GitHub to host their git repositories, Bitbucket, and more recently Gitlab, have become worthy alternatives. When users rely so much on those services for the everyday workflow, it became crucial for both, the providers and the users, to have almost non existing downtimes. One common approach to provide information to users about technical issues was to offer a status service (and API) for consu...| Spaghetti and Hammers - Articles
If you deal with external APIs (like Twitter, Facebook, Intercom, Github, and many others) on a regular basis there’s a big chance that you have already dealt with JSON answers before. JSON (JavaScript Object Notation) is a lightweight data-interchange format. It is easy for humans to read and write. It is easy for machines to parse and generate. It is a text format that is completely language independent but uses conventions that are familiar to programmers of the C-family of languages. JS...| Spaghetti and Hammers - Articles
This post was originally published on Codacy blog by me: I believe the Open Source movement is the biggest breakthrough in software development. Open Source has allowed many projects to increase the number of contributors (and contributions) to unreachable standards for any enterprise. Just take a look at the Linux kernel, which counts with 500,000+ commits and 5,600+ contributors. In this evolution, platforms such as SourceForge, Google Code, Bitbucket, and especially GitHub played a fundame...| Spaghetti and Hammers - Articles
Edit: You may want to have a look at the updated example using Play 2.7 instead of Play 2.4 at Play Framework and Slick example updated Typical nowadays applications need to store some persistent data frequently. And when we talk about persistent storage we are talking about databases. Among the most common applications, we have web applications. And it is uncommon to have a web application that does not require persistent storage. Building webapps in Scala is typically done using the Play fr...| Spaghetti and Hammers - Articles
For those who don’t know, the Play Framework is the standard web framework for Scala (also available to Java), and it is similar to many other MVC frameworks, such as Spring MVC, Ruby on Rails, Django, and so on. And it has been a while since I’ve been wanting to play a little bit and experiment the Play Framework. Unfortunately, I never had the time, or any good idea to start with it. And simply going through the available tutorials is not enough to learn about a library/framework, in my...| Spaghetti and Hammers - Articles
Last week, on September 1st, I started a new adventure on Codacy. Codacy is an automated code review tool that allows developers to improve code quality and monitor technical debt. It aims to improve the code review process. To achieve such goal, not only automates the code review process, but also integrates with existing project management tools such Bitbucket, Github, Travis CI, and so on. As usual, when getting a new job, you have to configure your workstation once again. Having a mac, yo...| Spaghetti and Hammers - Articles
It has been a while since my last post, but between some side projects, summer vacation, and personal hobbies, it hasn’t been exactly easy to get time to write something.

Recently I’ve finished reading the book ‘Languages in Seven Weeks’. It is part of Seven in Seven series and it approaches seven different programming languages: Ruby, IO, Prolog, Scala, Erlang, Clojure, and Haskell. The publisher, The Pragmatic Bookshelf, introduces this book by making reference to a recommendation by The Pragmatic Programmer, which states “You should learn a programming language every year”, and suggesting that this book will make you learn seven new languages in a...| Spaghetti and Hammers - Articles
Have you ever committed code that made you feel ashamed? Maybe, for instance, a print statement you used for debugging just because you were too lazy to use the debugger? Maybe you even had that crazy idea of using a not so pretty print message? (Don’t worry, we all felt desperate to that point.) If the project you are working on has strong code review practices then, those print statements should get caught before going to production. Nevertheless, the code review process may let pass thos...| Spaghetti and Hammers - Articles
