Conference presentation: Senior software developer recruiting and community management

Curious about senior recruiting and communities? Here’s a talk I did at Hirepalooza 2015. Here are the Hirepalooza 2015 slides, which might help, given a couple jumps in the video. This is the description from the talk:

Even if you have a limited budget you still need to recruit tech talent. Join Eric Siegfried, CEO of TangoSource as he talks about how to find and hire the most critical technical talent on your team– even when you have close to no budget. From this session you’ll learn how to build and leverage an ecosystem, relate more to senior talent, and raise the level of your team.

The Scrum retrospective meeting: an introduction.

Some people underestimate sprint retrospective meetings and think of it as simply the time when a sprint ends and they can move on to what’s coming next week. But in reality, this meeting provides an opportunity for the team to identify relevant action items to improve their performance. This is the moment where the team can meet and examine each other’s performance for the sake of the project. It’s also an opportunity to update and improve the team’s definition of done.

There are many ways to lead a retrospective meeting. I’ll share with you what has worked for us.

At the beginning of each meeting

Make the purpose of the meeting clear for everyone. If this is the team’s first retrospective meeting, it’s...

Benefits of WordPress + Docker in a production environment + troubleshooting guide.

Hello,

Even though we are a Rails development team, we use WordPress for our blog. We love Rails, but WordPress provides a robust solution for our blogging needs. And lately, we have been experimenting with Docker + WordPress.

So, why Docker?

There are quite a few straightforward reasons why we use Docker with WordPress, namely:

  • Docker reduces clutter.
  • We can run a couple of Rails applications and WordPress instances on the same server.
  • It helps with version conflict management in Rails apps
  • It allows for the duplication of a production server into staging for testing purposes.

 

We can “dockerize” an application, run it in our laptops, run tests and then deploy with confidence that it will work. If you are new to Docker, you should read What is Docker and Dockerizing...

Long live your app: MongoDB Replication

The scenario

Not so long ago a customer requested that we provide the highest server reliability that we could. The application was pretty big, with about seven servers per environment. We needed to increase reliability in web servers and databases. In this article, I’ll explain how we achieved that from the database side.

While searching for options, we found that MongoDB (which was the database engine we were using) offered several options that increase your database reliability, i.e.:
MongoDB – Sharding
MongoDB – Replication

We went for MongoDB Replication –also known as Replica Set– because our customer needed a solution ASAP, and the configuration needed is minimal. Besides, it offers whole database replication, which we needed to implement other security measures, like backups.

The product owner’s job: to say no.

Have you seen a team that doesn’t understand the reason behind developing certain feature? Have you had a sprint review where more than a half of the features are rejected? Or that the team develops a huge feature that doesn’t add any significant value to the product? If you’ve seen this in your project, it might mean that your Product Owner is doing something wrong.

We can consider the Product Owner to be the main stakeholder. She should own the product and determine direction. The reality is that the Product Owner role is different from that of a project manager, since she has the passion, the vision, and, unlike a project manager, has to say no to people. Let me explain.

Saying NO...

Angular.JS controller communication

AngularJS is a Javascript framework made by Google. Over the last few years, its popularity has increased exponentially. Its main features are double data binding, DOM control, form validation and the use of reusable components. Plus, it’s fairly easy to use, which makes AngularJS one of the top choices when looking for a Javascript framework.

When we start working with Angular, we come to this question very quickly: how can we set our controllers to communicate with each other? Which option is the best?

It is typically assumed that in Angular.js there should be only one controller per view. Sometimes, however, we have no choice but to have two controllers within the same page, and they will need to interact with each other.

Given...

Introducing Planning Poker: manage sprint planning and retros like a pro.

Intro

Are you happy with the app you use to do feature estimation in your Scrum process? We weren’t either. How about the way you collect feedback after a sprint is done? We’ve got you covered.

Introducing Planning Poker: the tool to manage Scrum pointing sessions AND retrospectives in the same place, under an Open Source license, for free! How sweet is that? In this post, we’ll tell you why we built this app, and what were we looking for (spoiler alert: you will see those expectations fulfilled in our app). Then, we’ll show you how it actually works, on a step-by-step tutorial to master the main features. Finally, we’ll refer to the technical stack and the reasons behind choosing those specific technologies....

A Tmux crash course: tips and tweaks.

~ Intro

If you are one of those devs who uses the terminal a lot and ends up with way too many tabs open, or practices pair programming, then this post is for you. During the last months, I’ve started using Tmux a lot. Since I’ve found it to be very useful, I thought I would write a post where I share a few recommendations and pro-tips. I’ll show you what Tmux is and how to use it in combination with Vim to make a more effective and elegant use of the Terminal.

So, this is what we’ll cover:

  1. Tmux basics.
  2. The best of Tmux
    1. Windows
    2. Panes
    3. Sessions
    4. Fast text navigation and copying

HTML5 Canvas: playing with shapes and images.

The World Wide Web Consortium (WWC) introduced Canvas with HTML5 last year. We think it’s a pretty interesting drawing tool. So, we decided to experiment with it and share our findings in the form of a short tutorial in this blog post. We’ll cover the basics and mention a couple of recommendations for deeper learning.

To start understanding Canvas, think of it as an area on your page where you can draw and render graphs. It’s user together with Javascript, taking advantage of its properties and methods. Its purpose is to be a container for graphics, as it has no drawing abilities on its own. It may seem like a simple element, however, it can be used for complex tasks, like creating 2D animations. You can see examples...
