When I was in grad school, I learned the hard way -- by my poor showings in data science competitions -- that I was not handling missing data correctly. That motivated me to learn how to handle missing data the right way.
What is missing data? In simple terms, it's data where values are missing for some of the attributes. Let's look at five techniques to handle it correctly.
Atop the Castle of Saint Barbara in Alicante, time sometimes seems to slow down, and words that once held grand meaning seem inadequate. I had a similar feeling both during and on the heels of DrupalCamp Spain, organized by the Spanish Drupal Association and held this year at Las Cigarreras cultural center in a seaside city that is one of the crown jewels of not only the Valencian Community but also of Spain.
Revered management thinker Peter Drucker once wrote, “If you can’t replicate something because you don’t understand it, then it really hasn’t been invented; it’s only been done.” In many ways content modeling in Drupal has been done without being invented. For this reason, we’re developing a discipline for content modeling at Acquia. It’s drastically reducing both costs and defect rates for us.
At no point in the history of digital content has there ever been such a dizzying proliferation of devices in our lives, and experiences we encounter and consume.
Mike Madison, a Technical Architect in Acquia Professional Services, recently completed a Drupal site build for a major public transit agency in the United States. We spoke with him about his experiences using BLT -- an open-source Acquia product that provides an automation layer for testing, building, and launching Drupal 8 applications -- on this project. Mike said that BLT has been a critical component of the project’s success, and has especially helped in three primary ways: by accelerating project spin-up, improving developer onboarding, and increasing development velocity and delivery consistency.
“The most compelling advantage of API-first Drupal is not the way it negates Drupal's presentation features, it's the way it enables the capabilities of the CMS to power multiple applications a
Acquia’s Professional Services team recently released an open-source application that demonstrates how Drupal and Node.js can easily be paired to create beautiful and functional decoupled applications. See how easy it was to create the Drupal backend using a combination of Acquia and Drupal community projects such as Lightning, BLT, and DrupalVM. This will allow you to follow the same process to rapidly create your own custom decoupled applications.
