On April 11 2013, at the ACCU 2013 conference in Bristol (UK), a 90 minute “Dynamic C++” tutorial will be presented:
Data from external sources comes in diverse types and brings along the need for datatype conversion. How can a C++ programmer accurately and efficiently transfer data from relational or XML database to JSON or HTML without stumbling over the C++ type checking mechanism? The answer is by using type erasure techniques; session will enumerate, explore and compare the most popular C++ type erasure solutions.
Given the above problem as well as 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 (including pending boost::any C++ standard proposal), it is obvious that there is a need for a way around the static nature of C++ language. There is also more than one solution to this problem; session will explore the internals of boost::[variant, any, type_erasure], folly::dynamic and Poco::Dynamic. Design, capabilities as well as pros and cons of each solution will be examined. Performance benchmark comparisons will be reviewed as well.
Type safety is an important feature of C++; type erasure is a necessary technique for modern software development. Session examines and compares existing solutions to these important concerns.
Stop by if you happen to be in the area or attending the conference.
Stable release 1.4.6 brings some bugfixes and minor enhancements. See the CHANGELOG for the details. This is planned to be the last release in the 1.4 series.
Development release 1.5.1 is a major step towards the next stable 1.6.0 release planned for this spring. See the CHANGELOG for what’s new.
Get the source code from the download page or directly from GitHub.
Current development branch is now frozen and tagged as 1.5.1 pre-release in GitHub.
Until release, the development branch will remain frozen and any changes will be pushed to separate branches.
Please download or check it out, run some tests, report bugs, etc.
git clone https://github.com/pocoproject/poco.git

1.5.1 Release is scheduled for Monday, December 24 2012.
Update: Release was postponed for at least a week. Pre-release archives can be downloaded from:
Update 2: Release is available now:
During the month of December, we will be transitioning to GitHub issue tracker. By the end of 2012, all SF issues will be either (a) resolved, (b) discarded or (c) moved to GitHub. Please enter new issues in GitHub issue tracker. If you have a patch, please submit it as a pull request.
The C++ Libraries and Tools from Applied Informatics are based on the POCO C++ Libraries and add additional features such as Remoting for RPC/IPC and SOAP/WSDL web services, Open Service Platform for building modular, extensible applications, DNSSD/Zeroconf, Universal Plug and Play, Fast Infoset processing or secure remote access to smart devices. New in release 2012.1 is support for C++ code generation from XML Schema and WSDL documents, allowing Remoting to invoke SOAP 1.1/1.2 web services created using other middleware technologies such as Java JAX-WS or Microsoft .NET WCF. In addition to SOAP 1.1 and 1.2, the new Remoting also supports MTOM, HTTP Basic and Digest authentication and HTTP compression (gzip content encoding), as well as remote events with the new TCP transport.
A free evaluation version is available for download.
This release brings support for Visual Studio 2012, as well as some bugfixes and enhancements. See the CHANGELOG for the details. Available on the download page.
We’ve been asked and nudged for a long time to make the move; like everything else, it was something that requires resources of time and effort so it did not happen as fast as it should have. But finally, we’ve made it over to GitHub and now we can enjoy the benefits. Branching and merging is simple and intuitive, forking is readily available; we already have

632* “forkers” and 27100* “stargazers“.
I like the code-centered paradigm of GitHub – everything (as it should) revolves around and is linked with code. My favorite feature is the “network graph” (depicted below) showing who forked and what changes were synced. We have a proto-wiki with roadmap and supported platforms.
So, if you have not done it yet, what the fork are you waiting for? Stop by, hang around and – fork it!

The POCO C++ Libraries source code is now on GitHub. The old Subversion repository on SourceForge will no longer be maintained.

This talk will give an update on recent progress and near-future directions for C++, both at Microsoft and across the industry, with some announcements of interest in both areas. The speaker is the lead language architect of Visual C++ and chair of the ISO C++ committee.
UPDATE (Nov 4 2012): It turns out 1.5 release was just in time for the front page.
After talk interview
It’s official! C++ now has it’s own “Marketing Department” and a reliable place to go learn about the language, where is it going and what’s happening around it.
According to isoccp.org About page, goals are:
1) To promote dissemination of correct and up-to-date information about modern C++.
2) To promote greater availability of high-quality C++ libraries, including both standard libraries (by reducing barriers to submitting and adopting libraries in Standard C++ itself) and community libraries (by having an organized, and ideally tool-supported, way for C++ developers to discover and use libraries).
To stay in tune with your favorite language, make sure to bookmark the above web site and visit often.
