Dynamic C++
by Alex Fabijanic
3:30 PM Saturday
Room 4218
The C++ static type system is beneficial in many ways; it can, however, also be a straitjacket. Is there a rationale for dynamic type layer on top of a statically typed language like C++? Given both historical (ANSI C union and void*, MS COM Variant, boost::[variant, any, lexical_cast]) and recent (boost::type_erasure, Facebook folly::dynamic) development trends, the answer is a resounding "yes".
This presentation is based on Poco::Dynamic::Var (aka Poco::DynamicAny) - a dynamic-typing set of C++ classes; furthermore, it will show the simplicity and practical advantages of mapping ad-hoc generated data sets of unknown type, size, and structure to C++ data structures.
Specifically, the presentation demonstrates how to:
(1) Execute a generic "SELECT * FROM Table";
(2) Dynamically map returned data (row/column count and types) to C++ data structures at runtime;
(3) Format the result as [XML, JSON, HTML, your-favorite-data-format-here];
(4) Stream the resulting formatted string to std::ostream compliant HTTP socket stream.
Surely, this must be very complicated to do in C++, right? Not at all - we'll demonstrate all of the above done with a single line of code and then peek under the hood to see where/how does the magic happen. Portable? Of course. Scalable? You bet - it's C++! The content of this presentation fits perfectly into modern AJAXian trends and we'll prove it with an ExtJS example; it prompts re-thinking of the rationale for (a) employing dynamic languages on the server side or (b) polluting HTML with server-side code.

Introducing the Clang C++ Compiler
by Chandler Carruth
1:15 PM Sunday
Room 4220
The dragon is on your side now!
Clang is a new, modern C++ compiler that was design from the ground up to bring much needed sanity to C++ development. It has user-centric diagnostics system that makes writing C++ code easier than many have dreamed possible. It provides the basis of a new era of IDE-like C++ tools that have deep and accurate understanding of your code and can automate away the most tedious and painstaking programming tasks. These refactoring and analysis tools are making C++ more fun to write than ever before. Finally, Clang is leading a rising tide of dynamic analysis tools that allow you to make C++ a truly safe language.
Come learn about this exciting new compiler, how to use it in your day to day programming, and how to make the most of your C++ development experience using these advanced tools.
I lead the LLVM and Clang team at Google, building better diagnostics, tools, and more. Previously, I worked on several pieces of Google's distributed build system. I make guest appearances helping to maintain a few core C++ libraries across Google's codebase, and am active in the LLVM and Clang open source communities. I received my M.S. and B.S. in Computer Science from Wake Forest University, but I disavow all knowledge of the contents of my Master's thesis. I am regularly found drinking Cherry Coke Zero in the daytime and pontificating over a single malt scotch in the evening.

Logic Paradigm for C++ [ Part 2 ]
by Roshan Naik
3:30 PM Saturday
Room 4220
This talk will build on top of the foundations laid in part 1. We will cover more examples to get a better feel for using the Logic paradigm and how to combine it with other paradigms. We will also see how an elegant multiparadigm framework can lead to powerful solutions by examining the impact on the design of a game and the ability to write query expressions in C++.
Roshan is a leading expert in multi-paradigm programming techniques and the author of Castor, an open source library which brings the Logic Paradigm to C++. He has worked on a wide range of systems including HP-UX virtual memory, search engines and ad serving engines.

Threads and Shared Variables in C++11
by Hans Boehm
2:45 PM Sunday
Room 5015
In spite of over 40 years of shared memory parallel programming, there has been a surprising amount of confusion surrounding the basic meaning of shared variables.
C++11 both added threads to the language, and clarified the behavior of shared variables. The approach relies on a careful definition of a "data race", which is treated as an error, and a guarantee of expected behavior in the absence of such data races.
We'll quickly introduce some of the thread support features in C++11 and then describe the rules for programming with shared variables. We'll illustrate the finer points of the "data race" definition by going through a number of small examples. Much of this is also applicable to C11.

C++11 Idioms
by Sumant Tambe
10:45 AM Sunday
Room 4306
C++11 feels like a new language. Compared to its previous standards, C++11 packs more language features and libraries designed to make C++ programs easier to understand and faster. As the community is building up experience with the new features, new stylistic ways of using them are emerging. These styles (a.k.a. idioms) give the new language its unique flavor. This talk will present emerging idioms of using rvalue references -- a marquee feature of C++11 as many renowned experts call it. You will see how C++11 opens new possibilities to design class interfaces. Finally, you will learn some advanced use-cases of rvalue references which will likely make you feel something amiss in this flagship feature of C++11. (This talk will assume some basic knowledge of rvalue references, move semantics, and perfect forwarding in C++11. If these concepts are new to you, I highly recommend Jon Kalb's session just before this one.)
Sumant is working for Real-Time Innovations after a PhD in distributed systems and has been programming in C++ for nearly a decade. He enjoys working on standards-based data distribution middleware for real-time systems and using C++ to solve interesting problems ranging from systems to meta-programming. He believes that knowledge is gained by spreading it.

Exception-Safe Coding in C++ Part II
by Jon Kalb
11:15 AM Saturday
Room 4301
Are you 100% confident that your code is exception-safe?
Safe usage of exceptions is a non-trivial problem that the industry has struggled with for the better part of two decades. If you have fear, uncertainty, or doubt about exception safety or just want to see the best practices for using exceptions in C++, this session is for you. We’ll start with “What is the problem we are trying to solve?” and discuss alternatives, acknowledge the challenges associated with exception usage, and cover some well-meaning but misguided attempts at safety. I will then present a set of guidelines that are the basis for safe exception usage and solid implementation techniques, including how to transition from an exception-unsafe legacy code base.
When we are finished you will know how to produce code that is easier to write, easier to understand, faster to execute, and 100% robust in the face of exceptions.
This update of last year's talk covers substantially more material including C++11. This talk won Best Tutorial at this year's BoostCon.

Logic Paradigm for C++ [ Part 1 ]
by Roshan Naik
1:45 PM Saturday
Room 4220
The Logic paradigm (LP) is a powerful, Turing-complete programming
paradigm that has seen little representation in mainstream languages.
LP is an important approach in Computer Science towards
what is sometimes referred to as the Holy-Grail of programming "The
user states the problem, the computer solves it". Origins of Logic
theory dates back to about 300 B.C. when Aristotle founded
Formal Logic to bring rigor to logical inferencing. The theory
matured into Modern Logic more recently (early 1900s) when Russell &
Whitehead showed that all of Mathematics could be reduced to Logic.
This talk will provide a fast track introduction to the basics of LP in C++
without indulging too much in arcane theory. We will observe how blending LP into existing C++ concepts allows programmers to come up with really cool solutions.
For this talk we shall use Castor, an open source C++ library which introduces LP into standard C++.
Roshan is a leading expert in multi-paradigm programming techniques and the author of Castor, an open source library which brings the Logic Paradigm to C++. He has worked on a wide range of systems including HP-UX virtual memory, search engines and ad serving engines.

C++11: Rvalue References, Move Semantics, and...
by Jon Kalb
9:15 AM Sunday
Room 3525
This presentation is on what Scott Meyers has called the marquee feature of C++11. Rvalue references is a feature introduced in the new 2011 ISO C++ Standard that enables both move semantics and perfect forwarding.
Move semantics improves exception-safe coding, increases code clarity, and and can enable dramatic increases in performance.
Perfect forwarding makes it much easier to create certain kinds of libraries that combine power and expressiveness with ease of use..

Generic Programming in C++: A real-world example
by Marshall Clow
5:00 PM Saturday
Room 8403
In this session, I will take a request from the boost mailing list:
| Why doesn’t boost have hex/unhex functions, I think they would be useful.
And walk through the design and implementation of these algorithms for the Boost.Algorithm library. Although the functions are simple, there are a surprising number of interesting design decisions that were made along the way – and I will explore them in this talk.
Issues covered:
1) Generic programming design
2) Dealing with iterators (including the problems with output iterators)
3) Template metaprogramming (including enable_if)
4) Boost.Exception
5) Fit and polish of code.
