React Mini Session: Let’s build a small React app together

1691 Kettering St.
Irvine, CA



React is one of the most popular JavaScript libraries on GitHub. Top sites like Instagram, Netflix, Airbnb, the Bleacher Report and Feedly use it, so knowing React is no longer optional. Facebook and Instagram created React to make it easier to build beautiful user interfaces.

React is a library, not a framework like Angular or Ember. It doesn’t require you to be a fully committed true believer to use it. You can quickly add React components to your existing site. Or go full-tilt and create an entire web app with help from libraries like Redux and React-Router.

Join us for an evening session and work with us as we build a small React app together. Along the way, we will describe the pieces of React and what they do. By the end of the evening, you will understand what React is and know whether you are ready to master it in our weekend session on March 25th and 26th.

We will also take a quick peek at React Native, which allows us to create cross-platform mobile apps in JavaScript using native user interface components. The results are so good; even native developers can’t tell that you built your app in JavaScript.

Please join us for a free evening of React. Learn what it is and what it takes to use it to create sophisticated websites. All attendees will also receive a discount code for our already low priced, weekend workshop.

Cyber Attacks and Defenses: Trends, Challenges, and Outlook

TBA - Irvine/Costa Mesa, CA




6:30 PM Doors Open & Networking

7:00 PM Announcements and Presentation

8:30 PM Meeting Adjourned

Event Details

A cyber attacker needs to find only one way in, while defenders need to guard a lot of ground. Adversaries can fully debug and perfect their attacks on their own computers, exactly replicating the environment that they will later be targeting. This is the situation today, which has been exacerbated by an increasing trend towards a software “monoculture” (in which there are only two major desktop operating systems and two major phone operating systems, one major office software suite, and so on).

One possible defense is software diversity, which raises the bar to attackers. A lot of academic and industrial research is currently investigating such software diversity, from simple ASLR (address space layout randomization) to more complex whole-program randomization. In the latter, a diversification engine automatically generates a large number of different versions of the same program, potentially one unique version for every computer. These all behave in exactly the same way from the perspective of the end-user, but they implement their functionality in subtly different ways. As a result, a specific attack will succeed on only a small fraction of targets and a large number of different attack vectors would be needed to take over a significant percentage of them. Because an attacker has no way of knowing a priori which specific attack will succeed on which specific target, this method also very significantly increases the cost of attacks directed at specific targets.

Unfortunately, attackers have now started assembling their attacks on the target itself, circumventing diversity. Hence, in the arms race between attackers and defenders, we are already at the point where yet another set of defenses is needed, before the previous one is even fully deployed across the software industry.

My talk will present a time-line of attacks and defenses, clearly illustrating a “cat and mouse game” in which defenses are almost always reactive to attacks that have already happened.  I will discuss his vision of how to get ahead of the attackers, and close by stating why, in spite of the bleak situation today, I am confident that we will eventually be able to stop most kinds of cyber attacks completely.
