They found their solution with the combined power of Neo4j and Linkurious, even though they encountered some ... Read More

Feed: Planet PostgreSQL. PoWA 4 is available in beta. New remote mode! The new remote mode is the biggest feature introduced in PoWA 4, though there have been other improvements. I’ll describe here what this new mode implies and what changed in the UI. If you’re interested in more details about the rest of the changes in PoWA 4, I’ll soon publish other articles for that. For the most hurried people, feel free to directly go on the v4 demo of PoWA, kindly hosted by Adrien Nayrat. No credential needed, just click on “Login”. Why is a remote mode important ...

Feed: Neo4j Graph Database Platform. Author: Jocelyn Hoppa. “Always ask why,” said Stephen O’Grady, Co-Founder of Redmonk.When deciding what projects to take on, developers should consider the broader context and the implications of what they’re being asked to build. So says Stephen O’Grady from Redmonk, a developer-focused industry analyst firm that tracks, among other things, the top 20 programming languages over time.In this week’s five-minute interview (conducted at GraphConnect 2018 in NYC), Stephen O’Grady shared his view of the use cases and future of graph technology. Where do you think graphs fit into the wider tech ecosystem?O’Grady: I think the ... Read More

Feed: Microsoft Azure Blog. Author: Parul Matah. This post is part of a 2-part series about how organizations are using Azure Cosmos DB to meet real world needs, and the difference it’s making for them. In part 1, we explored the challenges that led the Microsoft 365 usage analytics team to take action, the architecture of the new solution, and migration of the production workload. In this post, we’ll examine additional implementation details and the outcomes resulting from the team’s efforts. Finding the right partition key—a critical design decision After moving to Azure Cosmos DB, the team revisited how data ... Read More

Feed: R-bloggers. Author: John Mount. In this note we share a quick study timing how long it takes to perform some simple data manipulation tasks with R data.frames. We are interested in the time needed to select a column, alter a column, or select a row. Knowing what is fast and what is slow is critical in planning code, so here we examine some common simple cases. It is often impractical to port large applications between different work-paradigms, so we use porting small tasks as approximate stand-ins for measuring porting whole systems. We tend to work with medium size data ... Read More

Feed: SAS Blogs. Author: Rick Wicklin. Have you ever run a statistical test to determine whether data are normally distributed? If so, you have probably used Kolmogorov's D statistic. Kolmogorov's D statistic (also called the Kolmogorov-Smirnov statistic) enables you to test whether the empirical distribution of data is different than a reference distribution. The reference distribution can be a probability distribution or the empirical distribution of a second sample. Most statistical software packages provide built-in methods for computing the D statistic and using it in hypothesis tests. This article discusses the geometric meaning of the Kolmogorov D statistic, how you ... Read More
