And yet it has – and right now it’s flying higher than ever thanks to its 2.0 update. Snapchat’s story is surprising enough on face value but when you learn some of the more surprising twists and turns, the plot only thickens. Read on and let’s take a closer look at some of the things you probably didn’t know about Snapchat… ?Snapchat is Highly Personal If you’ve had your ear to the ground, then you may have heard the buzz about live streaming. Live streaming services are quickly becoming incredibly popular thanks to their ability to allow direct and live communication between a brand and its followers. But in fact, Snapchat has been providing something very similar for a long time. Snapchat allows you to update people about your trip to another country, it allows you to invite people to watch the public unveiling of your new product or service and it allows you to share a joke as you’re coming out the shower. This kind of personal communication has the power to create much more engagement, familiarity and trust. And if you look at the big names on Snapchat – like Arnold Schwarzenegger – then you’ll be able to easily see how it can be used to great effect. It Has Incredible Engagement Yes, Snapchat’s ‘instant’ nature gives it the potential to greatly increase engagement. And in reality, that’s exactly what it does. If ever you think you can’t make it big online, let Snapchat be an inspiring story to suggest otherwise. Snapchat is by no means some miracle feat of coding. Rather, this was actually a relatively poorly put together piece of code and would sap huge amounts of battery and CPU power when running in the background even! That’s not to say it’s a bad app – only that it’s all the more impressive it was able to do as well as it did. Facebook Tried to Buy Snapchat When it was enjoying its first major surge in popularity, Snapchat was offered a purchase bid from Facebook worth $3 billion. That’s a huge vote of confidence from the biggest social network on the planet… and Snapchat turned it down! ??Here’s Why You Need To Take A Close Look At Snapchat… ·Although often overlooked, Snapchat is one of the most powerful new social networks for driving traffic online…? ·Snapchatis all about socialization and a great way to interact with your brand? ·Snapchat was recently offered $3 Billion by Facebook… and they turned it down… this makes it clear that Snapchat is sure that it’s only getting bigger and better!? ·Engagement on Snapchat is MASSIVE, and growing… because all communication is focused on image and video sharing, your audience is very attentive and interested in anything you put in front of them…...Snapchat is adding 200 million new active users every single month!

Leverage Scala and the functional paradigm to build performant softwareAbout This Book·Get the first book to explore Scala performance techniques in depth!·Real-world inspired use cases illustrate and support the techniques studied and the language features·This book is written by Vincent Theron and Michael Diamant, software engineers with several years of experience in the high-frequency trading and programmatic advertising industriesWho This Book Is ForThis book assumes a basic exposure to the Scala programming language and the Java Virtual Machine. You should be able to read and understand moderately advanced Scala code. No other knowledge is required.What You Will Learn·Analyze the performance of JVM applications by developing JMH benchmarks and profiling with Flight Recorder·Discover use cases and performance tradeoffs of Scala language features, and eager and lazy collections·Explore event sourcing to improve performance while working with stream processing pipelines·Dive into asynchronous programming to extract performance on multicore systems using Scala Future and Scalaz Task·Design distributed systems with conflict-free replicated data types (CRDTs) to take advantage of eventual consistency without synchronization·Understand the impact of queues on system performance and apply the Free monad to build systems robust to high levels of throughputIn DetailScala is a statically and strongly typed language that blends functional and object-oriented paradigms. It has experienced growing popularity as an appealing and pragmatic choice to write production-ready software in the functional paradigm. Scala and the functional programming paradigm enable you to solve problems with less code and lower maintenance costs than the alternatives. However, these gains can come at the cost of performance if you are not careful.Scala High Performance Programming arms you with the knowledge you need to create performant Scala applications. Starting with the basics of understanding how to define performance, we explore Scala's language features and functional programming techniques while keeping a close eye on performance throughout all the topics.We introduce you as the newest software engineer at a fictitious financial trading company, named MV Trading. As you learn new techniques and approaches to reduce latency and improve throughput, you'll apply them to MV Trading's business problems. By the end of the book, you will be well prepared to write production-ready, performant Scala software using the functional paradigm to solve real-world problems.Style and approachThis step-by-step guide will help you create high performance applications using Scala. Packed with lots of code samples, tips and tricks, every topic is explained in a detailed, easy-to-understand manner.
