By Tom Tasker, EMEA Storage Partner Solutions Architect at AWSMicrosoft SQL (MSSQL) is an enterprise-level database application used by some of the world’s largest companies.

Feed: Puppet.com Blog RSS Feed. Author: ; How often are you exactly right? I mean, 100% perfect? It’s not often. When delivering new software and services to customers (internal or external), you’ve made a bet that what you’re providing is what the customer truly needs. The problem with traditional delivery is that you might be wrong, and by quite a bit. What if instead of optimizing for shipping the perfect thing when it’s ready, you optimized for feedback from your customer base? The goal of shipping now becomes learning, rather than checking off boxes on a requirement sheet. This is ... Read More

Feed: Puppet.com Blog RSS Feed. Author: ; One of the core principles of DevOps is that responsibilities should be shared across teams and there should be no silos. Silos can have a number of detrimental effects on product development, from making communication across teams less efficient to creating an “us v. them” mentality. One of the most insidious impacts of team silos is the “chuck it over the fence” anti-pattern, where teams complete their part of a project and then relinquish responsibility to the next downstream team. With this mode of operation, ownership is hard to establish until, ultimately, you ... Read More

Feed: R-bloggers. Author: R on Sastibe's Data Science Blog. Recently, I was tasked with a straightforward question: “In an A/B test setting, how many samples do I have to collect in order to obtain significant results?” As ususal in statistics, the answer is not quite as straightforward as the question, and it depends quite a bit on the framework. In this case, the A/B test was supposed to test whether the effect of a treatment on the success rate p had the assumed size e. The value of the success rate had to be estimated in both test and control ... Read More

Feed: AWS Government, Education, & Nonprofits Blog. Author: Professor Rainer Schmidt. Social information systems – how we share information – use both public systems such as social media and private systems internal to organizations such as internal blogs and wikis. These systems increasingly influence opinion-forming processes in societies and organizations, and supplement and sometimes replace traditional media such as newspapers, radio, and TV. The strength of social information systems lies in their ability to present previously unestablished opinions and viewpoints as fact, and can be used to disseminate false information, leading to polarization. The Munich University of Applied Science (MUAS) ... Read More
