Snapchat ?Marketing ?Success Virtually all social media sites out there have users communicating with text or chat…sure, some social media sites are starting to adopt video and there is some image sharing, but at the core, comments are left and messages are sent. That is NOT the case with Snapchat. Communication is all done through images and videos with the occasional small caption. This is how the younger generation likes to communicate… Short and sweet. Snapchat is one of the most unusual social networks to make it big online. You wouldn’t have thought that such a simple concept, handled arguably quite poorly to begin with, would become the huge behemoth it has today. 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!

Its wide use in server and cloud environments, its speed and ease of use, and its evident capabilities for data analysis, have made it a prime choice for developers who need to think about security. Security with Go is the first Golang security book, and it is useful for both blue team and red team applications. With this book, you will learn how to write secure software, monitor your systems, secure your data, attack systems, and extract information. Defensive topics include cryptography, forensics, packet capturing, and building secure web applications. Offensive topics include brute force, port scanning, packet injection, web scraping, social engineering, and post exploitation techniques. Style and approach John Leon has divided the book into two parts which present the team playing defense against anyone breaking into servers and the team playing (ethical!) offense to perform said attacks. All Go *s and programs are workable solutions that can be easily understood and expanded upon by anyone with a system administrator’s level view of networking and cloud-based systems.
