Feed: Big Data Made Simple. Author: Sharafudheen Mangalad. If you have this doubt whether Java can be used for Artificial Intelligence (AI), then, many brilliant Java developers in one voice will say a “YES”. These developers also have the opinion that Java is one of the best programming languages after Python for developing Artificial Intelligence solutions. One thing you need to realise is, there is no individual language only to develop Artificial Intelligence solutions. In spite of that, the existing tools help developers achieve great results when developing AI Solutions.Today, you’ll see the prevalence of Artificial Intelligence in most of ... Read More

Feed: Redis Labs. Author: Alex Milowski. During the 2020 wildfires in California, I, along with millions of others, have been constantly checking the PurpleAir website to monitor the air quality. In addition to looking for clean air to breathe, I was curious about how PurpleAir aggregated data from its sensors and was excited to discover that it had an API for accessing its data. It seemed a perfect opportunity to demonstrate the power of Redis as a database deployed using Kubernetes. In the past, some of my research focused on exposing geospatial data on the web. For this project, I ... Read More

Feed: Featured Blog Posts - Data Science Central. Author: Sharmistha Chatterjee. Importance of C++ in Data Science and Big Data Introduction and Motivation – Why C++ C++ is ideal for dynamic load balancing, adaptive caching, and developing large big data frameworks, and libraries. Google’s MapReduce, MongoDB, most of the deep learning libraries listed below have been implemented using C++. Scylla known for its ultra-low latency and extremely high throughput is coded using C++ acts as a replacement to Apache Cassandra and Amazon DynamoDB. With some of the unique advantages of C++ as a programming language, (including memory management, performance characteristics, and systems programming), it definitely serves as one of the most efficient tools for developing fast scalable Data Science and Big Data libraries. Further, Julia (a compiled and interactive language – ... Read More

Feed: What's New. Author: Steve Schwartz. Data is how we understand elections. In the leadup to major political events, we all become data people: we track the latest candidate polling numbers, evaluate policy proposals, and look for statistics that could explain how the electorate might swing this year. This has never been more true than during this year’s U.S Presidential election. Quality data and clear, compelling visualizations are critical to understanding the polls, and how the sentiment among voters could influence the outcome of the race. Today, Tableau is announcing a new partnership with SurveyMonkey and Axios to bring exclusive ... Read More

Feed: Planet PostgreSQL. pgRouting is a powerful routing tool, usually used for pathfinding/mapping/direction applications. (See Paul Ramsey's introduction to pgRouting here). It is, however, also a robust graph db implementation, and can be used for much more than just finding the directions to your great aunt Tildy’s. Yacht Rock (as if you didn’t know) is a music genre created well after its active era. It’s characterized by smooth dulcet sounds that bring to mind wavy blond-haired waspy men in boat shoes, and ultimately provides a sound that rocks, but won’t rock the boat.   ... Read More

Feed: AWS Big Data Blog. In today’s world, data plays a vital role in helping businesses understand and improve their processes and services to reduce cost. You can use several tools to gain insights from your data, such as Amazon Kinesis Data Analytics or open-source frameworks like Structured Streaming and Apache Flink to analyze the data in real time. Alternatively, you can batch analyze the data by ingesting it into a centralized storage known as a data lake. Data lakes allow you to import any amount of data that can come in real time or batch. With Amazon Simple Storage ... Read More

Feed: AWS Architecture Blog. When you want to optimize your Java application on AWS Lambda for performance and cost the general steps are: Build, measure, then optimize! To accomplish this, you need a solid monitoring mechanism. Amazon CloudWatch and AWS X-Ray are well suited for this task since they already provide lots of data about your AWS Lambda function. This includes overall memory consumption, initialization time, and duration of your invocations. To examine the Java Virtual Machine (JVM) memory you require garbage collection logs from your functions. Instances of an AWS Lambda function have a short lifecycle compared to a ... Read More
