Feed: Featured Blog Posts - Data Science Central. Author: Bill Schmarzo. There is a phrase in baseball about pitchers “pitching through pain” that refers to pitchers taking the mound to pitch even though they have aches and pains – sore arms, stiff joints, blisters, strained muscles, etc. The idea is that these pitchers are so tough that they can pitch effectively even though they are not quite physically right.  However, when the human system is asked to do something that it’s not prepared to do in the most effective manner, other bad habits emerge in an attempt to counter these ...

But with so many distributed databases and tools available today, it’s often difficult to understand what each one offers and how they differ. With this practical guide, Alex Petrov guides developers through the concepts behind modern database and storage engine internals. Throughout the book, you’ll explore relevant material gleaned from numerous books, papers, blog posts, and the source code of several open source databases. These resources are listed at the end of parts one and ... Read More

Feed: R-bloggers. Author: AbdulMajedRaja RS. REGEX is that thing that scares everyone almost all the time. Hence, finding some alternative is always very helpful and peaceful too. Here’s a nice R package thst helps us do REGEX without knowing REGEX. REGEX This is the REGEX pattern to test the validity of a URL: ^(http)(s)?(://)(www.)?([^ ]*)$ A typical regular expression contains — Characters ( http ) and Meta Characters ([]). The combination of these two form a meaningful regular expression for a particular task.So, What’s the problem?

Feed: CronJ. Author: Vignesh M; AI is been in our imagination for the last 40 50 years.In fact, from all the way from 2001 Space Odyssey to even like Ex Machina, there’s been a lot of movies about our fascination with AI.Unfortunately, that’s been a very negative twist around AI because ultimately all those movies are about the machines turning on humans and ultimately killing them. So I would like to offer a more optimistic outlook about AI. But it’s clear that this is something that’s really caught our imagination.The other thing that was clear was that this is all ...

Feed: Blog Post – Corporate – DataStax. Author: Sebastian Estevez. Yesterday at ApacheCon, our very own Patrick McFadin announced the public preview of an open source tool that enables developers to run their AWS DynamoDB™ workloads on Apache Cassandra. With the DataStax Proxy for DynamoDB and Cassandra, developers can run DynamoDB workloads outside of AWS (including on premises, in other clouds, and in hybrid configurations). The Big Picture The cloud has changed computing forever, and as cloud services continue to evolve up the stack, the new capabilities they offer developers come with trade-offs. One of the trade-offs developers, architects, and ... Read More

Feed: Blog Post – Corporate – DataStax. Author: Louise Westoby, Senior Director, Product Marketing. Historically, software was monolithic. In most cases, development teams would have to rewrite or rebuild an entire application to fix a bug or add a new feature. Building applications with any sense of speed or agility was largely out of the question, which is why software suites like Microsoft Office were generally released once a year. Much has changed over the last decade or so. In the age of lightning-fast networks and instant gratification, leading software development teams are adopting DevOps workflows and prioritizing CI/CD so ... Read More

Feed: Radar. Author: Mac Slocum. Radar trends began as an internal resource for O’Reilly. It’s a monthly list of things that I find interesting or important—possibly not “trends,” strictly understood, but ideas that might become trends. Most items on the list have links to media sources—some original sources, more frequently other reporting, whichever I think is more informative. Some items are personal observations or summaries of interesting conversations. Learn faster. Dig deeper. See farther. Many items are about technology, conceived rather broadly. Over time, topics will include biology and biotech, design and user experience, ethics, open source communities, energy, and ... Read More

Feed: Radar. Author: Mac Slocum. Editor's note: Welcome to the first O’Reilly Radar column. We plan to use this column to cover topics related to the themes that have our attention these days: AI/ML; Next Economy and Future of the Firm; Next Architecture; and tech-driven innovation and disruption. We’ll also venture outside of O’Reilly’s core focus on technology practitioners to include how technology fits into the modern economy, and offer the kind of information that can provide guidance and confidence to technology leaders facing this brave new world. The Radar team uses a combination of input from our wide-ranging social ... Read More

Feed: Radar. Author: Mac Slocum. Both quantitatively and qualitatively, the Radar team has uncovered a growing wave of change in software development and architectural trends. Organizations are increasingly choosing the combination of cloud, containers, and orchestration to implement microservices as their directional architecture. The need to support business processes and customer expectations—and to have flexibility, adaptability, and scaling for new projects and for migrating legacy systems—has organizations embracing the interrelated technologies and approaches we call Next Architecture. In this report, we cover background, technology and business drivers, and key components that define the Next Architecture concept. Every company has a ... Read More
