How to Build a Red Hat OpenShift PaaS Cartridge

Posted on (0 Comments)

A couple of weeks ago I had the opportunity to visit the Red Hat office in Mountain View to take part in a sort of corporate hackathon. Red Hat invited members from various companies to explore its OpenShift PaaS and build something called a cartridge at the event. These cartridges are not gray boxes that you plug into your old Nintendo console after furiously blowing out all the dust. Cartridges are ways users can extend the OpenShift platform. Third Party developers can create support for languages, databases or other environment requirements which might not exist on OpenShift in order to

If you’re a SendGrid customer you will no doubt have taken a look around your statistics dashboard a few times. It’s great isn’t it? Being able to get such a granular view of what’s happening with the email you send through us.

Command-lining SendGrid for Developer Productivity

Posted on (0 Comments)

I’m pretty bad at letting things break my flow. Twitter, Hacker News, the actual news, buying tech I don’t need; all things that are likely to happen if I leave my editor and head into the browser. Those tabs are just too damn easy to click on. Inspired by other developers and my fellow developer evangelists, I’ve been looking for ways to maximise my productivity when I’m coding. So, I decided to start building an application that would take the elements of SendGrid administration I was doing, remove the browser element, and bring it back to the terminal. The end

My First Hack as a Developer Evangelist

Posted on (0 Comments)

Hi I’m Kunal, I am a new Developer Evangelist at SendGrid. I want to introduce you to my first SendGrid hack, the OCR App. However, before I tell you more about my hack I want to give you a little insight behind my motivation. I wanted to create something that showcased the simplicity and power of our APIs. I also wanted it to be something that people could use after hearing about it. I thought it would be interesting to do a mashup between our SMTP & Inbound Parse APIs as well as Abbyy’s OCR SDK. What does this hack

“How to Send Email with Arduino” at NY Tech Meetup

Posted on (2 Comments)

Last week I had the distinct honor of being able to demo as the “Hack of the Month” at the New York Tech Meetup (NYTM). I didn’t know I was going to be demoing before I showed up and I got insanely lucky that I happened to have all the supplies I needed with me, but I managed to pull together a pretty good demo of some of the hardware hacks that I’ve been working on for the past few months. The video of the event is split into bookmarks, with my Arduino and laptop hack presentation just past halfway.
