HTTP is a protocol that allows browsers and web applications to communicate across the Internet. Everyone knows that HTTP is doing some important work, because “HTTP” is at the beginning of most URLs that you enter

Machine learning is a tool that every software engineer wants to be able to use. Because machine learning is so broadly applicable, software companies

Artificial intelligence is reshaping every aspect of our lives, from transportation to agriculture to dating. Someday, we may even create a superintelligence–a computer system that is demonstrably smarter than humans. But there is widespread disagreement on

Cruise is an autonomous car company with a development cycle that is highly dependent on testing its cars–both in the wild and in simulation. The testing cycle typically requires cars to drive around gathering data, and that data to subsequently be integrated into a simulated system called Matrix. With COVID-19, the ability to run tests

Grafana is an open source visualization and monitoring tool that is used for creating dashboards and charting time series data. Grafana is used by thousands of companies to monitor their infrastructure. It is a popular component in monitoring stacks, and is often used together with Prometheus, ElasticSearch, MySQL, and other data sources. The engineering complexities

Apache Airflow was released in 2015, introducing the first popular open source solution to data pipeline orchestration. Since that time, Airflow has been widely adopted for dependency-based data workflows. A developer might orchestrate a pipeline with hundreds of tasks, with dependencies between jobs in Spark, Hadoop, and Snowflake. Since Airflow’s creation, it has powered the

The life cycle of data management includes data cleaning, extraction, integration, analysis and exploration, and machine learning models. It would be great if all of this data management could be handled with automation, but unfortunately that is not an option. For most applications, data management requires a human in the loop. A human in the

Kubernetes continues to mature as a platform for infrastructure management. At this point, many companies have well-developed workflows and deployment patterns for working with applications built on Kubernetes. The complexity of some of these deployments may be daunting, and when a new employee joins a company, that employee needs to get quickly onboarded with the
