Feed: erwin Expert Blog – erwin, Inc.. Author: Danny Sandwell. Organizations have spent a lot of time and money trying to harmonize data across diverse platforms, including cleansing, uploading metadata, converting code, defining business glossaries, tracking data transformations and so on. But the attempts to standardize data across the entire enterprise haven’t produced the desired results.A company can’t effectively implement data governance – documenting and applying business rules and processes, analyzing the impact of changes and conducting audits – if it fails at data management. The problem usually starts by relying on manual integration methods for data preparation and mapping ... Read More

Feed: What's New. Author: Ken Flerlage. I stated earlier that my favorite part of the FiveThirtyEight chart was the arrow at the bottom that grows as you hover and shows which party would be gaining seats and how many. Creating the first iteration of this was relatively simple—it was just a bar chart that is either red or blue and grows in size based on a filter action sourced from the primary bar chart. To create the arrow points on each end, I used PowerPoint to create two custom shapes. Each shape is essentially a white rectangle with a transparent ... Read More

Feed: Redis Labs. Author: Dave Provenza. Introduction After we published our recent RedisGraph benchmarking results, the folks at TigerGraph replied with some thoughts. While we appreciate hearing our competition’s perspective, we’d like to address their accusation of fake news. In our blog post, we introduced a parallel requests benchmark. This test is the same K-hop neighborhood count query test created by TigerGraph, but for our test, we had 22 clients execute the queries against RedisGraph concurrently. We introduced the concurrent requests test because we believe it is representative of almost any real-time, real-world scenario. The results we published measured the ... Read More

Feed: R-bloggers. Author: Thinking inside the box. A new RcppArmadillo bugfix release arrived at CRAN today. The version 0.9.200.7.0 is another minor bugfix release, and based on the new Armadillo bugfix release 9.200.7 from earlier this week. I also just uploaded the Debian version, and Uwe’s systems have already create the CRAN Windows binary. Armadillo is a powerful and expressive C++ template library for linear algebra aiming towards a good balance between speed and ease of use with a syntax deliberately close to a Matlab. RcppArmadillo integrates this library with the R environment and language–and is widely used by (currently) ... Read More

Feed: R-bloggers. Author: R on Rob J Hyndman. The latest minor release of the forecast package has now been approved on CRAN and should be available in the next day or so.

Feed: Planet PostgreSQL. At work I needed to push data out from a Microsoft SQL Server 2005 to a PostgreSQL 11 instance. Foreign Data Wrappers was my first thought! Perl to the rescue was my second, but since I had some time, I decided to investigate the first way first. The scenario was the following: CentOS 7 machine running PostgreSQL 11, it is not my preferred setup (I do prefer either FreeBSD or Ubuntu), but I have to deal with that; Microsoft SQL Server 2005 running on a Windows Server , surely not something I like to work with and ...

Feed: Feed | Tractica. Author: . As vehicles grow increasingly connected and become packed with sensors, there is potential for AI-driven technologies to play a prominent role in the human-machine interface (HMI). It makes logical sense for voice-enabled smart assistants for car controls, infotainment, and more to become the dominant HMI as we move into the era of the connected car, with momentum and regulatory demand (New Car Assessment Program [NCAP]) for driver monitoring. Eventually, when we all become passengers and vehicles become moving entertainment centers in the autonomous vehicle era, these voice assistants will make even more sense. As ... Read More
