Feed: AWS Government, Education, & Nonprofits Blog. Author: publicsector. In many organisations, IT security and data governance processes can be complex since data is stored across multiple environments and applications. Data privacy, including data classification, is now a core component of security requirements. Organisations need an easier and more pragmatic approach in administering their data assets to mitigate operational risk.Mandatory data privacy regulations, including General Data Protection Regulation (GDPR), Health Insurance Portability and Accountability Act (HIPAA), and Information Security Manual (ISM) data stores were administered by IT security based on their environment, application, group of users, and/or use cases. Now, ... Read More

Feed: The Internet of Things on AWS – Official Blog. Author: Eknath Venkataramani. AWS IoT Device Defender supports your efforts to secure your IoT device fleet. AWS IoT Device Defender Detect establishes a baseline behavior for IoT devices and then identifies devices that do not conform as anomalous. AWS IoT Device Defender Detect operates on security profiles, which are applied to the entire device fleet, or to a thing group. From a security standpoint, security profiles specify your IoT device’s expected behavior. We recommend that you group devices that are expected to behave similarly into a thing group. Next, you ...

Feed: R-bloggers. Author: Learning Machines. Sorting values is one of the bread and butter tasks in computer science: this post uses it as a use case to learn what recursion is all about. It starts with some nerd humour… and ends with some more, so read on! Have a look at the following code and try to understand it: bogosort Obviously bogosort did its job… but in a ludicrously inefficient way! It just shuffles all values over and over until they are sorted by chance! In the worst case it just shuffles forever (i.e. until the sun swallows the earth ... Read More

Feed: Planet PostgreSQL. I want to take a few minutes for a deep dive into the effect your data model has on storage density when using PostgreSQL. When this topic came up with a customer, I explained my thoughts on the matter, but I realized at the time that I had never done a reasonably careful apples-to-apples test to see just exactly what the effect is, at least for a model sample size of one. So here it is ... Read More

Feed: Cambridge Intelligence. Author: Dan Williams. To help users make sense of their complex data, KeyLines – the graph visualization toolkit – offers an intuitive way to group and combine different nodes. We call these groupings combos. They’re great for reducing clutter and organizing your networks into something more manageable.Insightful user feedback has helped us make combos even better (you’ll have spotted the latest batch of great enhancements in KeyLines 5.1). There are more improvements to come as this powerful feature will soon move out of Beta development and become an established part of the KeyLines toolkit.How you style nodes ... 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: SAS Blogs. Author: Mary Beth Moore. Every day, military intelligence analysts sit behind computers reading a never-ending stream of reports, updating presentation templates and writing assessments. But intelligence is more than documenting events and sharing breaking news. It involves understanding and predicting complexities in human behavior across various organizational constructs and using facets of information to make assessments on past, current and future circumstances. The availability of both human and technological resources has a large affect on the quality of these assessments. For the past two decades, technology has advanced at an incredible rate. Yet the technology available to ... Read More

Feed: Featured Blog Posts - Data Science Central. Author: Sean Owen. An Introduction to Bayesian Reasoning You might be using Bayesian techniques in your data science without knowing it! And if you're not, then it could enhance the power of your analysis. This blog post, part 1 of 2, will demonstrate how Bayesians employ probability distributions to add information when fitting models, and reason about uncertainty of the model's fit. Grab a coin. How fair is the coin? What is the probability p that it will land 'heads' when flipped? You flip the coin 5 times and see 2 heads ... Read More

Feed: Cloudera Engineering Blog. Author: Tom Wheeler. In the last few years, IT security threats to enterprise systems have increased, which has necessitated installing log ingestion and analysis solutions in any enterprise network. This blog post illustrates how Cloudera built its own scalable solution for log ingestion and analytics using Apache Spot and Cloudera Altus. By leveraging transient workloads in the cloud, Cloudera reduced the solution’s operational costs by 50% when compared to traditional, persistent cluster approaches. At Cloudera, the Infosec team needed to build a centralized log ingestion and analytical solution to monitor all key systems in the company ... Read More

Feed: R-bloggers. Author: Michael. The use case is to create the same plot in different languages. I used this technique for Wikipedia plots. We are going to build a list containing all translations, we will then loop over each language, generating and saving the plot. # Mauna Loa atmospheric CO2 change # multi language plot for Wikipedia # Required packages library(tidyverse) library(gridExtra) library(scales) library(lubridate) # Translations ------------------------------------------------------------ language % group_by(year) %>% mutate(year_mean = mean(co2_filled, na.rm = TRUE), delta = co2_filled - year_mean, vdate = ymd(paste0("2015-", month, "-01"))) # Generate the plot for each language ------------------------------------- for (l in names(language)) { ...
