A few months ago I got a new computer and I have been very intentional about deciding what I install on it. From past experience I know that computers that are used as a development environment tend to get messy in no time since one might install all kinds of libraries, frameworks, dependencies, you name it, and to makes matters worse, you will probably run into version conflicts for any or most of those things. Hardly ever a development environment is a clean environment and I don’t know about you but there are very few things that I find more frustrating than wasting time troubleshooting development environment set up. Let me write the code already!

The context

Rails 5 introduced a big change in how it handles ActionController::Parameters (the parameters that you get on your Controllers): before Rails 5, if you called your params you would get a hash back and after Rails 5, you get an ActionController::Parameters object. You can see that by calling params.inspect and if you call .to_h on these parameters you should be good to go.

Se você já programa há algum tempo e não sabe JavaScript ou se está pensando em aprender a programar e não sabe por onde começar, aqui está a minha lista de motivos porque eu acho que você deveria aprender JavaScript (ou simplesmente “JS” no resto desse post):

A few years back when I got serious about learning to program to become a software developer, I remember hearing about version control and getting really confused about git and GitHub (one can add GitLab to this list also!). Are they the same thing? Eventually, I figured it out but this past week in a conversation with a coworker, who is interested in getting into software development, I noticed that they also were confused about this so I decided to write about it.

When I first heard about git bisect I thought it sounded scary and complicated, so I never looked for an opportunity to learn more about it and use it. That’s until last week when I ran into a bug in our master branch. I knew that the bug was not there two days before so I tested an earlier commit and confirmed that that older commit was a good one. Now, we had tens of commits in between. How to find out when exactly the bug was introduced? It would be impractical to check and test each individual commit.
