Feed: Planet PostgreSQL. In this post I will show you how I discovered that the backend was putting data into a new table (generate_plist) but the website was still using the ports.pkg_plist column. The result was stale data being shown on the website (for older ports) or no data at all (for newer ports). How long? Since Oct 2017, because that’s when configure_plist showed up on the website. Nobody noticed until recently. I can only guess that I made the backend changes with intent to change the frontend later. I should have created myself a ticket. Why was the change ... Read More

Feed: Featured Blog Posts - Data Science Central. Author: Alaa Mahjoub. In many cases, for an enterprise to build its digital business technology platform, it must modernize its traditional data and analytics architecture. A modern data and analytics platform should be built on a services-based principles and architecture. Introduction part 1, provided a conceptual-level reference architecture of a traditional Data and Analytics (D&A) platform. This part, provide a conceptual-level reference architecture of a modern D&A platform. Parts 3 and 4, will explain how these two reference architectures can be used to modernize an existing traditional D&A platform. This will be ... Read More

Feed: Featured Blog Posts - Data Science Central. Author: akash. Increased consumption of data, more powerful computing, and the strong inclination towards data-driven decisions in business have made data science a crucial part of today's business environment. According to IBM, there is a huge demand for data scientists and data analysts in the present time. Python and R are the two most popular tools for programming for data science. Python and R both are open-source and free and were developed back in the early 1990s. For practitioners of machine learning and data science, these two tools are absolutely essential. While ...

We start a new series on neural networks and deep learning. Neural networks and their use in finance are not new. But are still only a fraction of the research output. A recent Google scholar search found only 6% of the articles on stock price price forecasting discussed neural networks ... Read More

Feed: Matillion. Author: Julie Polito; It’s great when things go right when you’re loading and transforming your data. But it’s equally important, even more so, to know when things don’t go so well. Matillion ETL already has a number of ways to help make jobs more resilient to errors including explicit error handling, logging and notifications. However, as cloud infrastructures become more complex–often extending across multiple platforms–so do the ETL jobs that support them.  Feedback from our  customers confirms this new reality. Many of them say that failures are now  more problematic to diagnose because:Errors may be several layers deep within ... Read More

Originally published 21 April 2020 to the Field Notes blog, and updated in August 2020 with new prechecks to the account enrollment script.  Since the launch of AWS Control Tower, customers have been asking for the ability to deploy AWS Control Tower in their existing AWS Organizations and to extend governance to those accounts in their organization. We are happy that you can now deploy AWS Control Tower in your existing AWS Organizations. The accounts that you launched before deploying AWS Control Tower, what we refer to as unenrolled accounts, remain outside AWS Control Towers’ governance ... Read More

Feed: R-bloggers. Author: Dario Radečić. Deep Learning in R – MNIST Classifier with Keras In a day and age where everyone seems to know how to solve at least basic deep learning tasks with Python, one question arises: How does R fit into the whole deep learning picture? You don’t need deep learning algorithms to solve basic image classification tasks. Here’s how to classify handwritten digits with R and Random Forests. Here is some good news for R fans – both Tensorflow and Keras libraries are available to you, and they’re easy to configure. Today you’ll learn how to solve a well-known ... Read More

Feed: Planet MySQL; Author: MySQL Performance Blog; MySQL Shell is the advanced MySQL client, which has many excellent features. In this blog, I am going to explain the MySQL shell commands “show” and “watch”. Both commands are very useful to monitor the MySQL process. It provides more insights into the foreground and background threads as well.  Overview “show” and “watch” are the MySQL shell commands, which can be executed using the Javascript (JS), Python (Py), and SQL interfaces. Both commands are providing the same information, but the difference is you can refresh the results when using the command “watch”. The ... Read More
