Feed: Redis Labs. Author: Kyle Davis. First, let me warn you that I am not a game developer. So this post, which has been rattling around in my head for a number of years now, is partly a look at how a theoretical game would work with Redis but also a metaphor to help readers understand how Redis works.  Phew!  With all that out of the way, let’s talk about implementing a game that is powered by Redis. We’re going to call this game Super Redis Brothers—it’s an action platformer connected to a central server. It stars Redisman, who needs ... Read More

Recently, some colleagues and I attended the 2-day COVID-19 hackathon #wirvsvirus, organized by the German government. Thereby, we’ve developed a great application for simulating COVID-19 curves based on estimations of governmental measure effectiveness (FlatCurver). As there are many COVID-related dashboards and visualizations out there, I thought that gathering the underlying data ... Read More

Feed: AWS Partner Network (APN) Blog. Author: APN Partner Guest Post. By Ravi Yadav, Director, Ecosystem, Corporate Development & Strategy at D2iQThough containers vastly simplify the distribution of applications, Kubernetes ecosystems are so powerful that they, in turn, can become complex. This is particularly true in hybrid cloud environments. D2iQ Kommander simplifies Kubernetes container management, including governance, workload configuration, and life cycles. This post explains how to take advantage of D2iQ Kommander’s capabilities on Amazon Web Services (AWS). To continuously innovate, many organizations are anchoring their infrastructure on container management solutions. The open source project Kubernetes is now the de facto ... Read More

Feed: Planet MySQL; Author: Continuent; For this next blog in our Continuent MySQL Use Case series, we’re diving into a sub-series on the topic of ‘multi-master MySQL’.We’ll cover three (3) multi-master MySQL use cases as part of this sub-series focusing first on e-commerce to start with, and then following up with use cases from financial services and telecommunications. Multi-master replication for MySQL typically means that a user can write to any master node knowing that the write will be eventually consistent for all nodes in the cluster; unlike regular MySQL replication, where writes have to be applied to the sole ...

Feed: R-bloggers. Author: Learning Machines. Learning Machines proudly presents a guest post by Martijn Weterings from the Food and Natural Products research group of the Institute of Life Technologies at the University of Applied Sciences of Western Switzerland in Sion. The topic of this post will be the fitting with the R-package optim. Food? That sounds like a rather unlikely match for writing a post on a blog about quantitative analysis, however, there is a surprising overlap between these disciplinary fields. For example, whether you model the transport of a flavour molecule or transport of a virus, the type of ... Read More

Feed: R-bloggers. Author: the Geocomputation with R website. This post explains how to quickly get key R packages for geographic research installed on Ubuntu, a popular Linux distribution. A recent thread on the r-spatial GitHub organization alludes to many considerations when choosing a Linux set-up for work with geographic data, ranging from the choice of Linux distribution (distro) to the use of binary vs or compiled versions (binaries are faster to install). This post touches on some of these things but, its main purpose is to provide advice on getting R’s key spatial packages up-and-running on a future-proof Linux operating ... Read More

Feed: The Internet of Things on AWS – Official Blog. Author: Chris Snowden. IntroductionSolutions architects, developers, and system designers building IoT solutions need ways to properly secure data and functions that operate on data across the entire solution landscape. In this post, we describe a few design options for scaling authorization policies focused on multi-user and multi-device use cases with AWS IoT Core. We cover several scenarios, including varying levels of device-to-user cardinality and scale. This information is helpful for making security design and architecture decisions for solutions built on AWS IoT services. Security coverage is needed at each tier, ... Read More

Feed: Recent Announcements. RA3 nodes are built on the AWS Nitro System and feature high bandwidth networking and large high performance SSDs as local caches. RA3 nodes with managed storage monitor your workload patterns and deploy adaptive data management techniques, such as automatic fine-grained data eviction and intelligent data pre-fetching, to deliver the performance of local SSD while scaling storage automatically to S3. RA3 nodes remain fully compatible with all your existing workloads.  RA3 nodes are generally available in Asia Pacific (Seoul, Singapore, Sydney, Tokyo), Brazil (São Paulo), Canada (Central), EU (Frankfurt, Ireland, London, Paris), US East (N. Virginia, Ohio), ... Read More

Feed: AWS Partner Network (APN) Blog. Author: Anubhav Sharma. By Anubhav Sharma, Partner Solutions Architect, AWS SaaS FactorySoftware-as-a-Service (SaaS) presents developers and architects with a unique set of challenges. One essential decision you’ll have to make is how to partition data for each tenant of your system. Tenant isolation, performance, noisy neighbor effect, pricing strategy, and a range of other factors will influence the design choices you make. Your data partitioning strategy will determine how you choose to physically or logically separate one tenant’s data from another. You will also be required to come up with security measures to prevent ... Read More
