By Daniel Ehrenberg. Have you ever found yourself with a disappointing rounding error due to how Numb ers work, or using awkward workarounds to avoid thinking about decimals? It's a shame that JavaScript chose binary floating point as its basic numeric type when it causes all of these problems. What can we do about it?

At Greentube business is booming. However, for the last few years they have faced increasing problems scaling their product and headcount. Like many orgs, Greentube has a complicated SQL Server backend which supports many apps. In 2016, despite best efforts, the database was not in source control, deployments were manual and the production database schemas were out of sync. The core database team was struggling to keep up with the business’s rapid growth because so much time was wasted firefighting unexpected issues. The business recognised that the database was a bottleneck on the company’s growth. And that was an expensive problem. Come and learn from Manoj Lona, the DB Team Lead at Greentube, and Alex Yates, a DLM Consultant from DLM Consultants, about how last year they made the necessary technical and organisational changes that today enable GreenTube to deploy their database at the click of a button - allowing them to scale their product and headcount to meet business demand.

Microsoft Exchange Server is an email solution widely deployed within government and enterprises, and it is an integral part of both their daily operations and security. Needless to say, vulnerabilities in Exchange have long been the Holy Grail for attackers, hence our security research on Exchange. Surprisingly, we've found not only critical vulnerabilities such as ProxyLogon, but a whole new attack surface of Exchange. This new attack surface is based on a significant change in Exchange Server 2013, where the fundamental protocol handler, Client Access Service (CAS), splits into frontend and backend. In this fundamental change of architecture, quite an amount of design debt was incurred, and, even worse, it introduced inconsistencies between contexts, leading us to discover this new attack surface. To unveil the beauty of this attack surface and our novel exploitation, we'll start by analyzing this architecture, followed by 7 vulnerabilities that consist of server-side bugs, client-side bugs, and crypto bugs found via this attack surface. In the end, these vulnerabilities are chained into 3 attack vectors that shine in different attack scenarios: ProxyLogon, ProxyShell, and ProxyOracle. These attack vectors enable any unauthenticated attacker to uncover plaintext passwords and even execute arbitrary code on Microsoft Exchange Servers through port 443, which is exposed to the Internet by ~400K Exchange Servers. This attack surface has its unparalleled impact for a reason: security researchers tend to find vulnerabilities from a certain perspective, such as digging for memory bugs, injections, or logic flaws, but we took a different approach by looking at Exchange from a high-level architectural view and captured this architecture-level attack surface, which yielded multiple vulnerabilities. We hope this brings a new paradigm to vulnerability research and inspires more security researchers to look into Exchange Server. Last but not least, we'll provide hardening actions to mitigate such types of 0days in Exchange.

Slides by Matt Brasier, Principal Consultant at C2B2, from the Hands on Lab delivered at the JavaOne 2014 conference. ABOUT HOL: This session will demonstrate the depth and breadth of the information available via the JMX API. We will tools that come with the JDK to peer deep into the workings of the JVM and understand how to identify and solve common performance bottlenecks or other problems. Attendees will get examples of using tools like VisualVM and Jstat to interrogate the JVM, and how to interpret the data returned, and learn how to add JMX instrumentation to their own applications and expose this to monitoring tools. This will be a session that allows attendees to understand the power available to them in some of the overlooked core JVM features The session will use a combination of slides and examples that the attendees can code-along with on their own laptops, and will focus on what JMX is, how it works, and also how you can expose your own application MBeans and use these to monitor the application. In my work as a Java performance consultant, I have found that JMX and the basic JVM tooling that uses it, is not understood by developers, so this session is about raising awareness of these tools and allowing developers to get inside the JVM and their application to understand how it works (and write better code). In my experience, once developers understand the power of JMX and VisualVM, they find it very interesting, and often the best way to demonstrate it is by allowing people to work with it. The fact that the base JDK is all that is required to demonstrate this means that there are few pre-requisites for this session, and because it is based on a low level technology, it is of interest to people working on all aspects of Java. I think this could make popular talk which will help developers understand the magic and power behind the Java Virtual Machine.

The days of EJB’s being the center of the Java EE universe are coming to an end. CDI is increasingly becoming the de facto component framework, due to its flexibility and lack of legacy. Starting in Java EE 7 and continuing in 8, the Java EE platform is migrating to enable all of EJB’s best features to be usable in the CDI world. In this session, you’ll learn implementation-level details on how they relate to each other, where we are in the EJB/CDI alignment story, what trade-offs you might need to make, and what you have to gain from making the transition. You will walk out with runnable examples and vendor-level insights. This is the perfect session for heavy EJB users looking to keep up with Java EE’s transition to CDI.

The learning curve for security is severe and unforgiving. Specifications promise infinite flexibility, habitually give old concepts new names, are riddled with extensions, and almost seem designed to deliberately confuse. For a back-end REST developer, choking all this down for the first time is mission impossible. With an aggressive distaste for fancy terminology, this session delves into OAuth 2.0 as it pertains to REST and shows how it falls into two camps: stateful and stateless. We then detail a competing Amazon-style approach called HTTP Signatures, ideal for B2B scenarios and similar to what is use to secure all Amazon AWS API calls. Each approach will be explored analyzing the architectural differences, with a heavy focus on the wire, showing actual HTTP messages and enough detail to have you thinking, "I could write this myself." As a bonus at the end, well peak into a new IETF Internet Draft launched this year that combines JWT and HTTP Signatures into the perfect two-factor system that could provide a one-stop shop for business as well as mobile REST scenarios. Come to this session if you want to go from novice to expert with a bit of humor, a big picture perspective and wire-level detail.

The standard Salesforce Approval process can be limiting in many ways, especially in complex scenarios. What if there was a way to implement very flexible approvals where one can use Apex code to make data updates in unrelated records, dynamically generate next steps details, and compute assignees on the fly? And still use UI-based configurations to implement concrete approval processes. In this session, we will share ideas behind such a solution and show a few lines of code to get you started.

I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.
