Feed: Featured Blog Posts - Data Science Central. Author: ajit jaokar.  Nvidia CEO Jensen Huang proposed an idea which the media has labelled ‘Huang’s law’ along the lines of Moore’s law. Moore’s predicts that the number of transistors in an integrated circuit doubles every two years. As per Huang’s law, GPU performance will double every two years. Whether or not you subscribe to the idea of Huang’s law – the concept itself has far reaching implications for the AI stack – especially for Edge devices Nvidia claims that innovation is not only in the chip – but across the entire ...

Feed: Planet PostgreSQL. One of the new features coming in PostGIS 3.1 is fixed precision support. This new feature will require compilation with not yet released GEOS 3.9. There are a couple of functions already in PostGIS 3.1 that have this new feature -- they are ST_Subdivide, ST_Union, ST_SymDifference, ST_Union, and ST_UnaryUnion as summarized in What's new in PostGIS 3.1. To take advantage of these new to die for features, you'll need to have compiled your PostGIS with development GEOS 3.9 which is planned for release around the same time we get around to releasing PostGIS 3.1 ...

Feed: Planet PostgreSQL. Back in June, I wrote about testing Postgres extensions on multiple versions of Postgres using GitHub Actions. The pattern relies on Docker image, pgxn/pgxn-tools, which contains scripts to build and run any version of PostgreSQL, install additional dependencies, build, test, bundle, and release an extension. I’ve since updated it to support testing on the the latest development release of Postgres, meaning one can test on any major version from 8.4 to (currently) 14. I’ve also created GitHub workflows for all of my PGXN extensions (except for pgTAP, which is complicated). I’m quite happy with it. But I ... Read More

Feed: SAS Blogs. Author: Kagan Sen. Zorlu Son Aşama: Model İmplementasyonu Günümüzde neredeyse tüm organizasyonların iş kararları vermek için, veriden faydalanarak gerçek zamanlı içgörüler elde etmeye çalıştığı bir dijital yolculuk içerisinde olduklarını görüyoruz. Sınırlarını hayalgücümüzün ve yeteneklerimizin belirlediği veri analitiği bizlere sonsuz bir potansiyel sunuyor. 2019 yılında analitik yazılımlara 190 milyar Dolar yatırım yapılması da şirketlerin bu potansiyelin farkında olduklarını gösteriyor. Ancak bu kadar büyük yatırımlar yapılmasına rağmen: Boşa giden veya kullanıma çok geç alınan analitik modeller hem efor kaybına hem de yatırım getirisinin düşmesine sebep veriyor. Modeller kullanıma alınsalar dahi analitik yaşam döngüsü üzerinde yaşanan gecikmeler ve aksaklıklar model ... Read More

Feed: Planet PostgreSQL. This post by Postgres committer Andres Freund about improving Postgres connection scalability in Postgres 14 was originally published on the Azure Postgres Blog on Microsoft TechCommunity. I recently analyzed the limits of connection scalability, to understand the most effective way to improve Postgres’ handling of large numbers of connections, and why that is important. I concluded that the most pressing issue is snapshot scalability. This post details the improvements I recently contributed to Postgres 14 (to be released Q3 of 2021), significantly reducing the identified snapshot scalability bottleneck. As the explanation of the implementation details is fairly ... Read More
