Our racing thoughts

Vim: A sense of project

Vim (or Neovim) is an excellent text editor, it is lightweight, ubiquitous and customizable in its core, but those are secondary traits, what makes Vim shine are its fast-writing capabilities with powerful keyboard-centered composable commands.

Despite its benefits, there is a list of things which Vim can’t do like:

  • Advanced file management.
  • GIT integration.
  • Advanced code completion.
  • Code linting.
  • Pairing sessions.
  • Global find and replace.

All of those are indispensable tools for everyday development. Are Vim users condemned to live without them? Not at all, and I’ll show you how you can...

A quick guide to using Mapbox in Android apps


Google maps has been one of the developers’ preferred choices when thinking of adding maps to their applications but as prices increased and a reduction of free API calls took place, developers had to start looking for an alternative that let them work with a cheaper map tool and that’s when Mapbox started to gain popularity.

Mapbox is one of the largest platforms that provide designed maps for websites and mobile applications; according to its documentation, it offers features such as maps, search, and navigation as well as better map customization compared to other options such as LeafLet or OpenLayers (If you want to know how many maps platforms exists you can visits this link).

Remote work in pandemic times

One of the best things about working in the IT industry is that we are in a state of constant digital transformation, which means that we are able to use technology to adapt our processes and meet the high standards of a fast-paced world. 

It has been 7 weeks since we started to work entirely remotely at Tango, following the government’s recommendations to avoid the spread of the virus, but that doesn’t mean we are new in this game.

Just to add context, Tango has offered the possibility to work remotely, even before the pandemic situation. Consequently, we have been improving our process to manage distributed teams for the last decade. We know transitions to working...

Test Automation Strategy

The search for quality in a software product is the most important activity after the creation of said software and yet, there is so much we have to learn and to define. As time passes, the industry has also come up with a variety of ways to optimize testing tasks, one of them being testing automation.

A misconception is that UI Test Automation would suppress the need for Manual Testing and reduce development costs in a short period of time; far from the truth, manual testing is still a very important (if not the most) part of the software development process and will continue to be so in the foreseeable future.

The Problem


Memoization: Faster Ruby app

The performance impact that your code could have in a certain programming language and/or platform is often overlooked, which might make you prone to blame those tools, instead of analyzing what and how your implementation made your application slower. Memoization may help you to improve your application speed with a non-significant impact on readability or flexibility on your code when appropriately used.

What is Memoization?

Memoization is a technique where you can cache a process result in order to use it later without the need to run that process again. This has the potential to save a massive amount of computing/networking power, thus improving the general performance of your application.

A thoughtful insight into why Redis


It’s common for us developers or technology enthusiasts to encounter technology that we can use right out of the box without really knowing what that thing actually does. It was not long ago when I was first introduced to Redis, this magical thing that solves all sorts of problems. 

I was working on a Rails application when I first heard about Redis, but I wasn’t really trying to work with Redis per se, I was more likely trying to make Sidekiq work; a background processor for Ruby that needs Redis in order to work as I had always been expecting things to work, out of the box.

If you are not familiar with background processors on...

How to be a better developer without coding?

Entering a new company is always a challenge, a challenge that not only entails testing your technical knowledge but also how you interact with your co-workers.

Talking with friends and fellow programmers about their experiences when entering a new company, I gave myself the task of delving a little more into a specific topic “What qualities do you consider positive in a co-worker?” And considering his answers, I made my best effort to take the qualities that they mostly emphasized on as positive aspects of a co-worker. These capabilities are named “Soft Skills” according to Sophia Bernazzani.

What qualities do you look for in a co-worker?


6 reasons why you should stop using Java and use Kotlin instead


As an Android developer who started working with Android 4 years ago, I had to learn Java in order to create native applications. For the first two years, I learned a lot about Java and I started to feel that I was getting good at it. During this period, I heard you could use Kotlin to create Android apps but I always thought “There’s no way Google would deprecate Java, it’s their main language.”

A year passed, and first-class support for Kotlin was announced at Google I/O 2017. In 2018 Kotlin was voted as the second most loved programming language (StackOverflow).


Being a leader as an engineer

Have you heard the story about the two engineers and the manager who found a Genie lamp? This manager and his team were looking for a laptop with crucial information for delivering an app. While searching their storage room, they stumbled into an old oil lamp that would look cool in the office, so they decided to clean it. After a couple of rubs, a Genie comes out.

The Genie told the three he will grant one wish to each one of them, so the first engineer is quick to say: “I want to be in the Bahamas, living in my dream home and owning a yacht” Puff! He is gone. The second engineer screams: “I’m next! I want to be...

Is your organizational culture hurting your recruitment efforts?

“Why has it become so difficult to hire people in startups? Do you think you could send us more options? When would I have the first list?”

As a Technical Recruitment Leader, these are just some of the questions that I hear practically every day,  throughout the years of experience in several companies (Enterprise, Mid Sized Companies, and Startups).

I have realized that one of the most relevant factors, when it comes to attracting talent, is the organizational culture of the company. This, in turn, is part of its “Employer Brand.” Let’s accept it, saying, “I’ll talk to you about X or Y transnational company (that everyone knows...
