Feed: Planet MySQL; Author: Severalnines; April 2018 is not just a date for the MySQL world. MySQL 8.0 was released there, and more than 1 year after, it’s probably time to consider migrating to this new version. MySQL 8.0 has important performance and security improvements, and, as in all migration to a new database version, there are several things to take into account before going into production to avoid hard issues like data loss, excessive downtime, or even a rollback during the migration task. In this blog, we’ll mention some of the new MySQL 8.0 features, some deprecated stuff, and ... Read More

Feed: Planet PostgreSQL. One of the great things about PostgreSQL is its reliability: it is very stable and typically “just works.” However, there are certain things that can happen in the environment that PostgreSQL is deployed in that can affect its uptime, such as:The database storage disk fails or some other hardware failure occurs The network on which the database resides becomes unreachable The host operating system becomes unstable and crashes A key database file becomes corrupted A data center is lost There may also be downtime events that are due to the normal case of operations, such as performing ...

Feed: R-bloggers. Author: Przemyslaw Biecek. Version 0.2.1 of the modelStudio package reached CRAN this week. Let me shortly overview coolest new features (list of all changes). Short reminder: The modelStudio package creates an interactive serverless D3.js dashboard for exploration of predictive models, which is based on principles of Explanatory Model Analysis. With modelStudio interface, one can juxtapose instance-level model explanations (Break Down, Shapley values and Ceteris Paribus profiles), dataset-level model explanations (Partial Dependence Plots, Feature Importance, Accumulated Local Effects Plot) and data exploration plots (histogram and scatterplots). Examples below use a GBM model trained on the kaggle FIFA 19 dataset ... Read More

Feed: R-bloggers. Author: Learning Machines. We already covered the so-called Accuracy-Interpretability Trade-Off which states that oftentimes the more accurate the results of an AI are the harder it is to interpret how it arrived at its conclusions (see also: Learning Data Science: Predicting Income Brackets). This is especially true for Neural Networks: while often delivering outstanding results, they are basically black boxes and notoriously hard to interpret (see also: Understanding the Magic of Neural Networks). There is a new hot area of research to make black-box models interpretable, called Explainable Artificial Intelligence (XAI), if you want to gain some intuition ... Read More

Feed: AWS Government, Education, & Nonprofits Blog. Author: Michael Wasielewski. Customers with stringent regulatory or risk-averse considerations may look to Zero Trust architectures to refactor legacy applications or deploy new ones. This blog will help you evaluate your application architecture against Zero Trust principles and use Amazon Web Services (AWS) to build secure and scalable architectures.What is Zero Trust? Zero Trust security is a model where application components or microservices are considered discrete from each other and no component or microservice trusts any other. This manifests as a security posture designed to consider input from any source as potentially malicious ... Read More

Feed: SAS Blogs. Author: Sundeep Tengur. Ever wondered how great magicians can trick us into believing things that aren’t quite true? From David Copperfield’s flying illusion to one of Penn & Teller’s card tricks, they all have one thing in common: misdirection or the art of deception. Fraudsters, like magicians, are crafty individuals who use a series of techniques to appear as legitimate persons or businesses when in fact they are not. Once they gain access to the coveted goods or services, they bust-out and fall off the radar. “Now you see me. Now you don’t.”   In a fraud context, these ‘disappearing ... Read More

Feed: Planet MySQL; Author: Severalnines; With MySQL 8.0 Oracle adopted a new approach to development. Instead of pushing features with major versions, almost every minor MySQL 8.0 version comes with new features or improvements. One of these new features is what we would like to focus on in this blog post.  Historically MySQL did not come with good tools for provisioning. Sure, you had mysqldump, but it is just a logical backup tool, not really suitable for larger environments. MySQL enterprise users could benefit from MySQL Enterprise Backup while community users could use xtrabackup. Neither of those came with a ... Read More

Feed: Puppet.com Blog RSS Feed. Author: ; Everybody talks about how continuous delivery is desirable to deliver products faster, so you can get feedback faster, get to revenue faster, and compete effectively. That said, continuous delivery is not easy. Achieving continuous delivery requires you to focus on your internal processes. Being a skeptical person, I asked myself, "Will focusing on our internal processes really enable us to deliver value to customers, as and when needed?"In fact, we did significantly cut our release cycles. We also found that shortening our release cycles helped us solicit feedback along the way, and build ... Read More
