Feed: Featured Blog Posts - Data Science Central. Author: Bill Schmarzo. I’ve been reading the interesting and soul-searching (from a data scientist perspective) book from Cathy O’Neil titled “Weapons of Math Destruction”, or WMD as used in the book.  The book provides several real-world examples of how Big Data and Data Science – when not properly structured – can lead to ethically-wrong unintended consequences.  Chapter 3 “Arms Race: Going to College” describes how the college ranking system developed by “US News & World Report” in 1983 has created its own self-fulfilling, mis-aligned ecosystem. Because of the influence the “US News ... Read More

Remember just a few years ago when we were looking forward to now or a little beyond and imagining what applications AI/ML would have in different industries.  Some ... Read More

Feed: R-bloggers. Author: An Accounting and Data Science Nerd's Corner. The idea OK. We are at home. Again. Given that large parts of Europe and the U.S. are currently experiencing a second large wave of Covid-19 cases and that most European jurisdictions have reacted with more or less rigorous lockdown regulations, one wonders about the effects of these regulations on social distancing compared to the one in March/April. In a recent TRR 266 workshop on data visualization, we (Astrid and Joachim) used this setting to discuss a workflow on how to let data speak graphically. This blog post, which is ... Read More

Feed: AWS Public Sector Blog. Author: Subash D'Souza. Modern data engineering covers several key components of building a modern data lake. Most databases and data warehouses, to an extent, do not lend themselves well to a DevOps model. DataOps grew out of frustrations trying to build a scalable, reusable data pipeline in an automated fashion. DataOps was founded on applying DevOps principles on top of data lakes to help build automated solutions in a more agile manner. With DataOps, users apply principles of data processing on the data lake to curate and collect the transformed data for downstream processing. One ... Read More

The latest Puppet State of DevOps Report shows that 63% of the respondents have at least one internal platform.

The definition of a “platform” isn't set in stone though. Many organizations still struggle to put together a platform team that is really able to add value to the development teams. It's a challenge to build a team with the proper mindset ... Read More

Feed: AWS Big Data Blog. The Amazon Redshift Data API makes it easy for any application written in Python, Go, Java, Node.JS, PHP, Ruby, and C++ to interact with Amazon Redshift. Traditionally, these applications use JDBC connectors to connect, send a query to run, and retrieve results from the Amazon Redshift cluster. This requires extra steps like managing the cluster credentials and configuring the VPC subnet and security group. In some use cases, you don’t want to manage connections or pass credentials on the wire. The Data API simplifies these steps so you can focus on data consumption instead of ... Read More
