Electricity Map: Real Time Visibility of Power Generation with Olivier Corradi - Episode 157

Summary

One of the biggest issues facing us is the availability of sustainable energy sources. As individuals and energy consumers it is often difficult to understand how we can make informed choices about energy use to reduce our impact on the environment. Electricity Map is a project that provides up to date and historical information about the balance of how the energy we are using is being produced. In this episode Olivier Corradi discusses his motivation for creating Electricity Map, how it is built, and his goals for the project and his other work at Tomorrow Co.

GoCD is the on-premise open source continuous delivery server created by ThoughtWorks and modeled after the ideas in the Continuous Delivery book by Jez Humble and David Farley.

With GoCD’s comprehensive pipeline modeling, you can model complex workflows for multiple teams with ease. And GoCD’s Value Stream Map lets you track a change from commit to deploy at a glance.

GoCD’s real power is in the visibility it provides over your end-to-end workflow. So you get complete control of and visibility into your deployments, across multiple teams.

Say goodbye to deployment panic and hello to consistent, predictable deliveries.

To learn more about GoCD, visit gocd.org for a free download. Professional Support and enterprise add-ons, including disaster recovery, are available.


When your website experiences an error, Airbrake alerts you in real-time, and gives you all the details you need to fix the bug fast. Some of the most useful tools that Airbrake provides for faster resolution are:

  • Exception aggregation to understand the how many users are being affected, so that you can prioritize the work you are doing to have the biggest impact
  • Contextual information to understand how certain states of the application contribute to the exception being raised, and which environments are affected
  • Deployment tracking so that you can easily see whether a new feature is the source of an error
  • Integration with all of the other tools that you use, such as automatically creating issues in GitHub and linking to the line of code where the error came from

Right now, Podcast.__init__ listeners can try Airbrake free for 30 days, plus get 50% off the first 3 months on the Startup plan. To get started, visit airbrake.com/podcastinit today.


Preface

  • Hello and welcome to Podcast.__init__, the podcast about Python and the people who make it great.
  • When you’re ready to launch your next app you’ll need somewhere to deploy it, so check out Linode. With private networking, shared block storage, node balancers, and a 200Gbit network, all controlled by a brand new API you’ve got everything you need to scale up. Go to podcastinit.com/linode to get a $20 credit and launch a new server in under a minute.
  • Finding a bug in production is never a fun experience, especially when your users find it first. Airbrake error monitoring ensures that you will always be the first to know so you can deploy a fix before anyone is impacted. With open source agents for Python 2 and 3 it’s easy to get started, and the automatic aggregations, contextual information, and deployment tracking ensure that you don’t waste time pinpointing what went wrong. Go to podcastinit.com/airbrake today to sign up and get your first 30 days free, and 50% off 3 months of the Startup plan.
  • To get worry-free releases download GoCD, the open source continous delivery server built by Thoughworks. You can use their pipeline modeling and value stream map to build, control and monitor every step from commit to deployment in one place. And with their new Kubernetes integration it’s even easier to deploy and scale your build agents. Go to podcastinit.com/gocd to learn more about their professional support services and enterprise add-ons.
