The SendGrid Ambassador Programme

Posted on (0 Comments)

Over the last year I’ve had the joy and privilege of being in charge of the SendGrid Ambassador Programme for Europe, the Middle East, and Africa (EMEA). My colleague, Yamil, has been in charge of the Ambassador Programme over in the United States and Latin America. If you’ve read my previous blogs, you’ll know by now that one of my absolute favourite parts of this job is teaching. I value teaching higher than anything. I believe if you have knowledge to share, share it. That being said, I jumped at the opportunity in December last year to take on the Ambassador Programme

The Value of Open Source (Part 2)

Posted on (0 Comments)

I wrote a few weeks ago about How I Value Open Source, the first part in this two-part blog series. The post covered my own thoughts on Open Source (OS), and its values to me. This post aims to cover more real-life fundamentals of OS, a deeper dive into OS and of course, the business value that lies in OS. I’ve also included a video from my original presentation about Open Source for WXG 2014 at the bottom of this post! Defining Open Source… If you look up the term Open Source (OS), you’ll probably find a bunch of articles telling

How I Value Open Source (Part 1)

Posted on (0 Comments)

This article is a personal look at Open Source, and how I value it. Part 2 will be a deeper dive into Open Source. Its true values, success stories, horror stories, licenses, and much more. Make sure you come back to read that one! I gave a talk last week at WXG 2014 on “The Value of Open Source.” This topic is something near and dear to all of our hearts here at SendGrid, and was definitely an eye opener for me; revealing a lack of Open Source uptake in the developer community. Around 1/3 of my audience didn’t embrace Open Source

Young Rewired State & Code on the Road

Posted on (0 Comments)

“It was a sea of Blue SendGrid T-Shirts. Everywhere I looked, I saw SendGrid! You guys rock!” My first answer when asked the question “What do Developer Evangelists do?” is always: We empower and nurture developers. In previous talks I’ve given and articles I’ve written, I’ve described how teaching, mentoring, empowering, and nurturing are the most important parts of my job, and there’s no age limit to which this help is confined. In the many hackathons I (and the rest of the Developer Evangelist team) travel to, I see developers of all ages and I’m never more impressed, and quite

Intro to Golang

Posted on (0 Comments)

An Introduction to the Go Programming Language (And Why I Love It) If you follow me on Twitter, you’ll no doubt know that I’m a huge fan of Go. You may have read my endless stream of Tweets ogling its brilliance, complaining about its few pitfalls, and bathing in the sweet, sweet light that is the over-indulgent default package set. But why? Why am I constantly marveling over this language, and frequently choosing it above others? I hope to clear that point up in this blog, introduce you to Golang, its wonders, its pitfalls, and introduce you to how SendGrid is

What is NoSQL? Four Things, Actually

Posted on (0 Comments)

I’m almost certain the majority of you will have heard the term “NoSQL.” I’m sure many of you know exactly what it means, and some of you already use it in production! But for those who are unfamiliar–what is NoSQL? This is an overview of the many different options across four types of NoSQL databases. NoSQL is a Database? Yes, it is! But you knew that already, right? In the Database world, we have almost always been accustomed to a type of database known as a relational database. These include the very common MySQL, PostgreSQL, SQLite and MSSQL. In the

Build a Scheduled News Reader with Golang, Reddit and SendGrid

Posted on (0 Comments)

I have too many good things to say about Go. I absolutely love the language. I could write a full article just on how much I love it and why. Instead, I’ll use Go to help you learn more about Go. Very meta. Luckily, I am not the only person on our Developer Relations team that loves Go. Yamil is a keen Gopher, and has already written a basic Golang wrapper for the SendGrid API. But especially since the engineering team is adopting Go, we need more examples. As the title states, we will be building a Scheduled News Reader
