Improving the Lives of People with Diabetes

Today, many people with diabetes are choosing to manage their condition using devices called continuous glucose monitors (CGMs). Not only do they replace the need for most finger prick testing, but they also provide a stream of data round the clock. However, like all data, it’s only as useful as the tools that analyze it.

That’s where Sugarmate comes in. Created by serial entrepreneur Josh Juster to help manage his own condition, Sugarmate combines a Heroku back-end with web, mobile, and smartspeaker apps to provide life-changing alerts and analysis for people living with diabetes.

Overcoming Fear Of Failure with a Leadership Coach

As part of my MBA at Carnegie Mellon University, I enrolled in a Leadership development certificate program. I was given the opportunity to work with an amazing Leadership Coach, ( Laura Maxwell ). Laura helped me on my journey of “overcoming my fear of failure”. As part of the program, I was able to share my story with the dean, professors, and the leadership development center at CMU. Since this is a rather common experience, I wanted to share my story with all of you as well.

This story starts, as many do, in childhood. Growing up in India, there has…

Saved by the Schema: Using JSON Schema to Document, Test, and Debug APIs

Heroku has many public API endpoints. Each of these endpoints needs to be tested so that we know how they work, and documented so that our customers (and other API consumers) know how they work. Follow along, and we’ll learn how Heroku uses JSON Schema to test and document our Platform API – and how it helped us uncover an unexpected bug, rooted in the way the Oj gem parses Big Decimals.

JSON Schema files are like blueprints that define the structure and semantics of other JSON documents. When a JSON Schema file is applied to a JSON document, you can…

Stuff Goes Bad

The Heroku Routing team does a lot of work with Erlang, both
in terms of development and maintenance , to make sure the platform scales smoothly
as it continues to grow.

Over time we've learned some hard-earned lessons about making systems that can
scale with some amounts of reliability (or rather, we've definitely learned what doesn't work), and about what kind of operational work we may expect to have
to do in anger.

This kind of knowledge usually remains embedded within the teams that develop
it, and tends to die when individuals leave or change roles. When new members
join the team, it…

Retrospectives

Retrospectives are a valuable tool for software engineering teams . Heroku consistently uses retrospectives to review operational incidents , root cause problems, and generate remediation tasks to improve our systems. Increasingly we use retrospectives for another purpose: to improve teamwork and interactions on projects. Here we intentionally avoid technical discussions and focus on the emotional and human aspects of work, with the goal of creating positive insights into how to improve as a team.

When

The most common times people conduct retrospectives are after some bad incident, or at the conclusion of a big project.…

Heroku Casts: Windows Setup

Getting the entire ruby stack up and running on Windows is a bit tricky. To help out the process we’ve posted a new Windows setup docs page .

This 10 minute screencast walks you through the process. It follows the outstanding instructions put together by Sarah Mei for the Ruby on Rails Workshops.

Heroku Casts: Setting Up Custom Domains

NOTE: This documentation is out-of-date and no longer supported. It will not work with the current version of the Heroku platform. For the latest information about setting up custom domains on Heroku please use this article from the Heroku Dev Center.

Today is a twofer on the screencast front.

Setting up custom domains & DNS is one of those necessary evils that no one likes, and is way more confusing than it should be. Adding insult to injury, there’s not one solution for all cases. At a high level, the process is fairly…

Heroku Casts: Creating Your First App

We’re introducing a series of screencasts going over how Heroku works, how to use it, and some common ways to make your experience better.

To kick this off, I’ve put together a quick <5 minute overview of creating your first Heroku application.

Follow all our videos on our vimeo page

If you’ve got ideas on other screencasts you’d like to see, let us know in the comments!

Watch Remi Showcase Ruby On Rails and Rack Deployment

It’s been a bit of a blur here at Heroku HQ in the past couple of weeks. However, amidst all the launch activity we did notice a screencast so sweet we thought we’d share it with you. It really covers the whole platform exceptionally well, and we particularly dig how it manages to show off both Rails and Rack app deployment.

Big ups to Remi for putting this together, and way to shame us for not getting any official screencasts together for the new and improved Heroku. 🙂

Fork Our Docs

Heroku is now sporting an updated docs layout at docs.heroku.com . These new docs should be much easier to navigate and link to.

We built this as a standalone Sinatra app serving Markdown files, partially inspired by Assaf Arkin’s approach to Buildr. This makes it as snappy as staticly rendered pages, while retaining the flexibility of a dynamic app on the backend.

The docs app is deployed as a regular app on Heroku (just like this blog ). Nothing special-case here: we deploy with git push, just like any other Heroku user. Dogfooding is good…
