From Internal IT to Hacking Robots in Warsaw

Posted on (0 Comments)

This post comes from Kevin Grablin, IT Operations Engineer and SendGrid’s newest employee ambassador. “How would you like to go to Makerland in Warsaw?” I almost fell off the ski-lift at Eldora when Tim Falls (Director of Developer Relations) offered me the opportunity to fly 5,302 miles to Warsaw Poland to attend the first ever Makerland conference. He was offering me my first chance to play the role of a SendGrid Ambassador and attend an amazing event. It’s important to understand why this was such a huge deal for me, as my role in SendGrid is not that of a

Productivity Tools for Work-Life Balance

Posted on (0 Comments)

Working smart is part of any job. As a developer evangelist, I have to play multiple roles, and there are some tools that I always rely on to help me do a better/faster job. Here are some of them, and hopefully they can also be of use to you. Email Tools Boomerang Boomerang for Gmail is a Chrome/Firefox/Safari extension that lets you schedule emails to be sent later, or set reminders. I love this tool and have been using it non-stop since the day I installed. Replying to emails at 1am (not recommended, but it happens) and don’t want to

Animated GIFs Inside Your Inbox

Posted on (0 Comments)

Want to bring a smile to your face? Try sending yourself an animated GIF. Once a sign of Web 1.0, these graphics are now such a form of expression that there’s a startup just to search them. In this post, I’ll show you how to use an API to find GIFs and the SendGrid Inbound Parse Webhook to request specific search terms. The end result, of course, are animated GIFs inside your inbox.   The demo application uses Giphy to search for animated GIFs. Before I show the technology behind the application, try it out using either the email or

An Update On Yahoo’s DMARC Policy

Posted on (0 Comments)

A recent change in Yahoo’s DMARC validation policy may be preventing your messages from being delivered. Recently, Yahoo made a significant change in their Domain-based Message Authentication, Reporting, and Conformance (DMARC) policy. DMARC is a system for implementing Domain Keys Identified Mail (DKIM) and Sender Policy Framework (SPF) validation and authentication. With a DMARC policy in place, if an email address does not match the domain server/service it originated from, it is bounced or blocked. This is a great security measure for preventing emails from companies spoofing mail domains from reaching the inbox. Yahoo has introduced a DMARC record that

Inside the Hackathon Organiser’s Backpack

Posted on (1 Comment)

I’ve done my fair share of hackathon organising over the years. From small 30 person “specialist” hacks, to larger, 200+ affairs like Music Hack Day London. Over that time I’ve built up a checklist of items that I try to ensure I have with me on the day to make sure everything runs smoothly. This is by no means an exhaustive list, and only covers the scrappier DIY end of the hackathon spectrum. There’s certainly going to be more insight from people who read this too, so I’d love to see contributions in the comments below.   The Hackathon Backpack
