How Ruckit and Heroku are Modernizing Construction

Alex Hendricks turns up the radio in the cabin of his ‘91 Ford LT8501. He’s drowning out the noise of the construction crew 100ft ahead as they make progress on a brand new bridge in Waco, Texas. Alex isn’t here to take in the sight of fresh new infrastructure. He’s in his truck waiting for the go-ahead to deliver a payload of hot mastic asphalt to the bridge crew.

Alex has a ticket in his …

“Do I Qualify?” And Other Questions Imposters Must Ask Themselves

A word of caution from a former AP Computer Science teacher who, with zero real-world programming experience, quit her dependable teaching gig to become a software engineer: Imposter Syndrome is never late to class.

When we grow competent in our craft, yet continue to feel unqualified for our role, that feeling is known as "Imposter Syndrome." The syndrome was with me before I started, it’s here with me now, and it will probably be with …

Building with Web Components and Their Advantages Over Third-party Libraries

In the early years of web development, there were three standard fundamentals upon which every website was built: HTML, CSS, and JavaScript. As time passed, web developers became more proficient in their construction of fancy UI/UX widgets for websites. With the need for newer ways of crafting a site coming in conflict with the relatively slow adoption of newer standards, more and more developers began to build their own libraries to abstract away some of …

Join us for a Live Q&A Chat with Salesforce Product Managers

Wade Wegner is SVP of Product for Salesforce Platform.

On a recent and all-too-short trip to London, I was humbled to have developers in the community spend time with me and other product managers at the UK Salesforce Tower. Building on the massively popular open dialogue with developers that we initiated at Dreamforce last year, our discussion was a transparent conversation with developers who have been building on the Salesforce platform.

I was incredibly inspired …

Using Research Grants to Foster Innovation

As CEO of Disney, Michael Eisner had a policy that any employee could come to his office and pitch an idea. He believed that breaking down hierarchical barriers allowed innovative ideas to come from anywhere, and it worked. Disney invested in many of those pitches, some of which became the kernels for films like The Little Mermaid and Pocahontas.

At Heroku, we know our employees are full of innovative ideas waiting for investment. …

PostgreSQL 12 Generally Available on Heroku

After a successful evaluation period, PostgreSQL 12 is now the default version for new Heroku Postgres databases and an available upgrade for existing databases.

I want to emphasize a few key changes and improvements in Postgres 12:

Native Table Partitioning Concurrent Operations

Native Partitioning was introduced in PostgreSQL 10 and performance improvements for improved parallel processing were added in PostgreSQL 11. Updating tables, altering partitions blocking queries, and executing concurrent operations for Native Partitioning were …

Ruby 2.7.0: The Traditional Holiday Release Is Here

When Heroku launched in 2007 there was only a single Ruby version that could be used on the platform. In 2012 Heroku began to support multiple Ruby versions. Since then, we’ve had a holiday tradition of releasing the new versions of Ruby on the same day they come out, which always happens on Christmas day (December 25th).

If you’re new to the community, you might be curious about where releasing a new minor version …

The Curious Case of the Table-Locking UPDATE Query

Update: On closer inspection, the lock type was not on the table, but on a tuple. For more information on this locking mechanism see the internal Postgresql tuple locking documentation. Postgres does not have lock promotion as suggested in the debugging section of this post.

I maintain an internal-facing service at Heroku that does metadata processing. It’s not real-time, so there’s plenty of slack for when things go wrong. Recently I discovered a Postgres …

Let It Crash: Best Practices for Handling Node.js Errors on Shutdown

This blog post is adapted from a talk given by Julián Duque at NodeConf EU 2019 titled "Let it crash!."

Before coming to Heroku, I did some consulting work as a Node.js solutions architect. My job was to visit various companies and make sure that they were successful in designing production-ready Node applications. Unfortunately, I witnessed many different problems when it came to error handling, especially on process shutdown. When an error …
