Feed: Percona Database Performance Blog. Author: Jervin Real. Jervin Real  | September 19, 2017 |  Posted In: MySQL, ProxySQL, Security, SSL PREVIOUS POST In this blog post, we’ll look at how ProxySQL improves MySQL SSL connection performance. When deploying MySQL with SSL, the main concern is that the initial handshake causes significant overhead if you are not using connection pools (i.e., mysqlnd-mux with PHP, mysql.connector.pooling in Python, etc.). Closing and making new connections over and over can greatly impact on your total query response time. A customer and colleague recently educated me that although you can improve SSL encryption/decryption performance with the AES-NI ... Read More

Feed: R-bloggers. Author: Shirin's playgRound. I have written a blog post about why I love R and prefer it to other languages. The post is on my new site, but since it isn’t on R-bloggers yet I am also posting the link here: Working in Data Science, I often feel like I have to justify using R over Python. And while I do use Python for running scripts in production, I am much more comfortable with the R environment. Basically, whenever I can, I use R for prototyping, testing, visualizing and teaching. But because personal gut-feeling preference isn’t a very ... Read More

Feed: R-bloggers. Author: Christoph Safferling. Q: What has 8 legs, 8 arms and 8 eyes?A: 8 pirates. Avast, ye scurvy scum! Today be September 19, the International Talk Like A Pirate Day. While it’s a silly “holiday”, it’s a great chance to switch your Facebook to Pirate English (“Arr, this be pleasing to me eye!”). Also, it’s as good a reason as any to go sailing the Internet Main, scouring for booty (data)! Well, any excuse, y’know… What is today known (more or less) as “Pirate English” (the bit with all the “arrr!”, “ahoy, ye matey!”, etc) is in fact ... Read More

Traffic Light (source: Bertsz) Learn how to rewrite monoliths into microservices at the O’Reilly Velocity Conference, taking place in London Oct. 17-20. Use code ORM20 to save 20% on your conference pass (Gold, Silver, and Bronze passes). Microservices are small programs, each with a specific and narrow scope, that are glued together to produce what appears from the outside to be one coherent web application. This architectural style is used in contrast with a traditional "monolith" where every component and sub-routine of the application is bundled into one codebase and not separated ... Read More

Feed: Microsoft Azure Blog. Author: Corey Sanders. Just one month ago, we announced our increased investment in Terraform. It is amazing to see the progress we have already made together with HashiCorp and the Terraform community. In the last month alone, we added support for Azure Container Instances and Azure Event Grid to the Terraform provider. Today at HashiConf, I announced native Terraform support built-in to the Azure Cloud Shell. I also announced 8 verified Azure Modules as part of the Terraform Module Registry launch. Now is a great time for you to try Terraform on Azure. Terraform Module Registry ... Read More

Feed: R-bloggers. Author: business-science.io - Articles. Employee turnvover (attrition) is a major cost to an organization, and predicting turnover is at the forefront of needs of Human Resources (HR) in many organizations. Until now the mainstream approach has been to use logistic regression or survival curves to model employee attrition. However, with advancements in machine learning (ML), we can now get both better predictive performance and better explanations of what critical features are linked to employee attrition. In this post, we’ll use two cutting edge techniques. First, we’ll use the h2o package’s new FREE automatic machine learning algorithm, h2o.automl(), to ... Read More

Feed: MapD Blog - Thoughts on GPU databases, data visualization and integrated analytics. Author: MapD Team. Twitter is an excellent way to gain insight into a wide variety of social phenomena. Data can be sliced in many different ways, looking at user, geography or topic/hashtag as well as diving down to the level of individual tweets. In fact, MapD originated when Todd Mostak needed to build a better interactive analysis tool to understand the Arab Spring. Streaming data from Twitter was added later. MapD recently released an open source Tweetmap Demo online showing roughly 390 million tweets. The code is ... Read More

Feed: All - O'Reilly Media. Author: Justin Francis. Filter (source: Pixabay) Attention readers: We invite you to access the corresponding Python code and iPython notebooks for this article on GitHub. Given all of the higher level tools that you can use with TensorFlow, such as tf.contrib.learn and Keras, one can very easily build a convolutional neural network with a very small amount of code. But often with these higher level applications, you cannot access the little inbetween bits of the code, and some of the understanding of what’s happening under the surface is lost. In this tutorial, I’ll walk you ... Read More
