Parker Phinney, creator of Interview Cake, continues his discussion from a previous episode with Julián Duque, a developer advocate at Heroku. Interview Cake provides different interview questions and programming exercise that adapt to the programming language that a candidate is working on. Since their coursework is essential to helping users succeed, they made an effort to ensure that the work was done accurately.

First, they provided their entire course curriculum in Python, the programming language they were most familiar with. Then, they hired a team of language experts to convert those Python lessons into various other languages. Finally, they hired a second team of experts to...

Join Charlie Gleason, a designer and developer at Heroku, as he interviews two people representing The Difference Engine: Kimberly Lowe-Williams, its founder and Executive Director, and Rachel Marro, a recent graduate. The Difference Engine is a Chicago-based nonprofit with the goal of empowering professionals from nontraditional backgrounds to launch their careers in tech. They do this through an apprenticeship web development program, mock technical interviews, and ways to highlight their relevant experience.

Kimberley stresses that The Difference Engine expects applicants to have some familiarity with coding. The programs are designed to help adults with prior work experience navigate...

Erin Allard is a Platform Support Engineer at Heroku, and she's interviewing Ben Orenstein, one of the co-founders of Tuple. Screenshare was a popular pair programming app that was discontinued after being acquired by Slack. Finding no other alternative for this functionality, Ben and his friends built Tuple.

Ben spent much of the early months of Tuple investigating pricing strategies, because he understood that the business wouldn't exist unless he could charge a reasonable price customers would be willing to pay. This process also reduced the risk of their efforts, knowing that they could burn through months of savings with the likely goal of being able to turn a profit. To that...

Giorgio Regni, the co-founder and CTO of Scality, and Robert Blumen, a DevOps engineer at Salesforce, cover the basics of on prem, public cloud, private cloud and multi-cloud. The discussion covers business drivers, use cases, division of workloads, architecture, and networking concerns present in each of these categories.

For enterprises, there is no "one cloud fits all" approach to building applications. The public cloud is more than an experimental platform for non-critical applications and unproven products - nor is the path of all computing migrating to its final home in the public cloud inevitable. Instead enterprises are arriving at the right mix of on premises private...

David Morganthaler, an Account Manager at Heroku, interviews two members from Kevala: Emmanuel Levijarvi, its engineering lead, and Teddy Ward, a software engineer. Kevala is building a one-to-one map of a community's energy grid, to identify how power is produced and model how it's consumed. They pull data from public sources and aggregate data to reliably predict when energy will be needed, and what an optimal price to pay for that energy generation.

Balancing the exact amount of energy that people want alongside the amount that is being produced is an incredibly hard problem for the utility sector. If you don't produce enough, electronics won't work and vehicles...
