“We will reject Apps for any content or behavior
that we believe is over the line. What line, you ask?
Well, as a Supreme Court Justice once said, "I'll
know it when I see it". And we think that you will
also know it when you cross it.”

Wordpress is a powerful and ubiquitous tool, but it uses resources and introduces vulnerabilities. Most campuses have several instances of Wordpress running, and they are usually hacked into simple CMS functionality. We'll show you why we end up doing that and how we can set up Cascade Server to adress those needs. For the few situations where Wordpress really is the better tool, we'll give an overview of best practices for using Cascade Server's Wordpress connector while minimizing risk and upkeep costs.

If you've ever developed code for processing data, you know what a mess it can be—especially on Hadoop. You lack debugging tools, instant feedback, automated tests, and a sane deploy. Mortar has developed a modern framework for data processing on Hadoop and Amazon Elastic MapReduce. It is a free, open framework providing instant, step-by-step execution visibility, automated testing, reusable components, and one-button deployment. See how Mortar demonstrates this framework on Amazon EMR on a sample data set to solve a big data problem.

Designing the code of a large application in production and scaling up to thousands of users while doing it all in Node.js is a challenge that no developer should face alone. I will discuss how we have developed a highly decoupled, plugin-based architecture and a decentralized infrastructure for Cloud9 IDE, along with the technologies we've developed and the difficulties we faced in order to build the largest Node.js application that exists in production.

Media queries blah blah blah. You've all heard that talk a hundred times, so I won't do that. Instead, I'll go beyond the obvious, looking at what we can do today to adapt our front-ends to different browsing environments, from mobiles and other alternative devices to older browsers we may be called upon to support. You'll learn advanced media query and viewport tricks, including a look at @viewport, Insights into responsive images: problems, and current solutions, providing usable alternatives to older browsers with Modernizr and YepNope, other CSS3 responsive goodness - multi-col, Flexbox, and more, and finally where RWD is going ‚Äî matchMedia, CSS4 media queries, etc.

With more memory available, system performance of three Dell devices increased, which can translate to a better user experience Conclusion When your system has plenty of RAM to meet your needs, you can efficiently access the applications and data you need to finish projects and to-do lists without sacrificing time and focus. Our test results show that with more memory available, three Dell PCs delivered better performance and took less time to complete the Procyon Office Productivity benchmark. These advantages translate to users being able to complete workflows more quickly and multitask more easily. Whether you need the mobility of the Latitude 5440, the creative capabilities of the Precision 3470, or the high performance of the OptiPlex Tower Plus 7010, configuring your system with more RAM can help keep processes running smoothly, enabling you to do more without compromising performance.

Discord is a free app offering voice, video, and text chat functionalities, primarily catering to the gaming community. It serves as a hub for users to create and join servers tailored to their interests. Discord’s ecosystem comprises servers, each functioning as a distinct online community with its own channels dedicated to specific topics or activities. Users can engage in text-based discussions, voice calls, or video chats within these channels. Understanding Discord Servers Discord servers are virtual spaces where users congregate to interact, share content, and build communities. Servers may revolve around gaming, hobbies, interests, or fandoms, providing a platform for like-minded individuals to connect. Communication Features Discord offers a range of communication tools, including text channels for messaging, voice channels for real-time audio conversations, and video channels for face-to-face interactions. These features facilitate seamless communication and collaboration. What Does NSFW Mean? The acronym NSFW stands for “Not Safe For Work,” indicating content that may be inappropriate for professional or public settings. NSFW Content NSFW content encompasses material that is sexually explicit, violent, or otherwise graphic in nature. It often includes nudity, profanity, or depictions of sensitive topics.
