Feed: AWS Compute Blog. Author: Anuneet Kumar. This post is contributed by Adam McLean – Solutions Developer at AWS and Chirill Cucereavii – Application Architect at AWS In this post, we show you how to automatically refresh the container instances in an active Amazon Elastic Container Service (ECS) cluster with instances built from a newly released AMI. The Amazon ECS-optimized AMI  comes prepackaged with the ECS container agent, Docker agent, and the ecs-init upstart service. We recommend that you use the Amazon ECS-optimized AMI for your container instances unless your application requires any of the following: A specific operating system Custom security and monitoring agents installed ...

Feed: R-bloggers. Author: Lorenz Walthert. How do you program? I feel like there is a lot of advice out there, but most ofit focuses on the micro level rather than on the macro level. That’s why Idecided to think about what makes one an efficient programmer on a macro level. Spend time on improving skills that help you become more productive inthe long run.For example, it’s a fact that git is the version control system of choice. Andthere is no reason why this should change tomorrow. Or in 5 year’s time. Thatin turn means that you need to know the ... Read More

Feed: Featured Blog Posts - Data Science Central. Author: Samual Alister. Data science is among the one of the most discussed term in last few years. Digital industry is hugely dependent on exchange of data. But most of us just know about basic terminology about data science like it just about studying data and finding out some important information from them. But it is more than that. So, what exactly those data scientists do? Why does everyone want one? And how do you become one? Let’s start with what does a data scientist do? Same as a business analyst, data ... Read More

Feed: Planet MySQL; Author: Scotch.io; The importance of online code editing platforms cannot be overemphasized. As much as we love our local IDE's, one too many times we find ourselves needing to quickly share and or collaborate with a friend or colleague in our local projects. Table of ContentsIn cases like this, online playgrounds give us that added functionality to write and run codes as well as share snippets and have colleagues test it out and give us feedback. In this post, we'll be looking at the top 5 online code editors for JavaScript in no particular order. CodePen is ... Read More

Feed: Planet PostgreSQL. Common table expressions, aka CTEs, aka WITH queries, are not only the gateway to writing recursive SQL queries, but also help developers write maintainable SQL. WITH query clauses can help developers who are more comfortable writing in imperative languages to feel more comfortable writing SQL, as well as help reduce writing redundant code by reusing a particular common table expressions multiple times in a query.A new patch, scheduled to be a part of PostgreSQL 12 major release later in the year, introduces the ability, under certain conditions, to inline common table expressions within a query. This is a huge ... Read More

Feed: R-bloggers. Author: Mi Chung. Google searches and the amount of searches for terms can show how interested the public is in that subject. After all, the act of Googling something is result of someone having some level of interest in that topic. The data that comes from Google searches and its statistics can give insight and different interpretation to all subjects, since there are infinite reasons someone would search for something. In this Shiny App, the interest in five rappers, including Cardi B, Drake, Kanye West, Jay Z, and 21 Savage, are explored through their Google search statistics.  In ... Read More

Feed: R-bloggers. Author: xi'an. A new Le Monde mathematical puzzle in the digit category: Given 13 arbitrary relative integers chosen by Bo, Abigail can select any subset of them to be drifted by plus or minus one by Bo, repeatedly until Abigail reaches the largest possible number N of multiples of 5. What is the minimal possible value of N under the assumption that Bo tries to minimise it? I got stuck on that one, as building a recursive functiion led me nowhere: the potential for infinite loop (add one, subtract one, add one, …) rather than memory issues forced ... Read More

Feed: R-bloggers. Author: Rcrastinate. I am currently reproducing a statistical analysis a colleague of mine conducted in Stata. Obviously, I am using R for the replication. I came across what I think is Stata’s default behavior when using log-transformed axes. This is an example. What I like about the tick lines on the axes here is that they show the “distortion” that is introduced by the logarithmic transformation. In other words: Distances between the non-transformed values shrink as we reach higher values and the tick marks show just that. I wanted to reproduce this with R and ggplot2 which does ...

Feed: R-bloggers. Author: John Mount. R users have been enjoying the benefits of SQL query generators for quite some time, most notably using the dbplyr package. I would like to talk about some features of our own rquery query generator, concentrating on derived result re-use. Introduction SQL represents value use by nesting. To use a query result within another query one writes the query to be used inside the query using the values. R query generators can also represent value use by nesting, but they also tend to expose a sequential pipe notation where value use is represented by sequencing ... Read More

Feed: AWS Compute Blog. Author: Anuneet Kumar. This post is contributed by Brent Langston – Sr. Developer Advocate, Amazon Container ServicesLast week, AWS announced enhanced Amazon Elastic Container Service (Amazon ECS) support for GPU-enabled EC2 instances. This means that now GPUs are first class resources that can be requested in your task definition, and scheduled on your cluster by ECS. Previously, to schedule a GPU workload, you had to maintain your own custom configured AMI, with a custom configured Docker runtime. You also had to use custom vCPU logic as a stand-in for assigning your GPU workloads to GPU instances ... Read More
