biicode 2.0 is out
by biicode Team
Who's biicode for?
For C/C++ developers that think a dependency manager is needed, biicode is a multiplatform tool and hosting service that allows you to build your projects easily, integrate third party code and reuse code among projects with just #includes.

For all the people that develop for Android, a new version( revision 10d) of the Android Native Development Kit has been released.
Android NDK Revision 10d available
From the release log:
- Made GCC 4.8 the default for all 32-bit ABIs. Deprecated GCC 4.6, and will remove it next release. To restore previous behavior, either add
NDK_TOOLCHAIN_VERSION=4.6to ndk-build, or add--toolchain=arm-linux-androideabi-4.6when executingmake-standalone-toolchain.shon the command line. GCC 4.9 remains the default for 64-bit ABIs.- Stopped all x86[_64] toolchains from adding
-mstackrealignby default. The NDK toolchain assumes a 16-byte stack alignment. The tools and options used by default enforce this rule. A user writing assembly code must make sure to preserve stack alignment, and ensure that other compilers also comply with this rule. (GCC bug 38496)- Added Address Sanitizer functionality to Clang 3.5 support to the ARM and x86 ABIs. For more information on this change, see the Address Sanitizer project.
- Introduced the requirement, starting from API level 21, to use
-fPIE -piewhen building. In API levels 16 and higher, ndk-build usesPIEwhen building. This change has a number of implications, which are discussed in Developer Preview Issue 888. These implications do not apply to shared libraries.
And much more ...

A short article about two error-detection features in GCC:
Address and Thread Sanitizers in GCC
by Dodji Seketeli on Red Hat Developer Blog
From the article:
Since their 4.8 version, the C and C++ compilers of the GNU Compiler Collection are equipped with built-in memory and data race errors detectors named Address Sanitizer and Thread Sanitizer.
This article intends to quickly walk you through the highlights of these two interesting tools.

Now available the presentation slides and videos of the LLVM Developers' Meeting that occured last october:
Notably can be found talks about security in the source code, the OpenMP implementation or optimizations to be made by the compiler, and many more.

An article about a security feature in Visual Studio 2015, called Control Flow Guard.
Visual Studio 2015 Preview: Work-in-Progress Security Feature
by Jim Hogg
From the article:
By simply adding a new option to your Project, the Visual C++ compiler will inject extra security checks into your binaries. These will detect attempts to hijack your code. The check will stop execution of your code, before the hijacker can do damage to your data or PC...

A new major version of the Qt has been released.
Qt 5.4 released
From the news article:
I am happy to announce that Qt 5.4 has been released today and is available for download from qt.io. Together with Qt 5.4, we have also released Qt Creator 3.3 and an update to Qt for device creation on embedded Linux and embedded Android.
But let’s start with Qt 5.4. One of the main focus areas of this Qt release has been around Web technologies and we have a lot of cool new things to offer there...

In case you missed it, now you can develop web apps in C++ to run natively on Google Chrome. This tutorial shows how to develop a Native Client module in C++ and build and run it using PNaCl toolchain:
C++ Tutorial: Getting Started (Part 1)
This tutorial shows how to build and run a web application using Portable Native Client (PNaCl). This is a client-side application that uses HTML, JavaScript and a Native Client module written in C++. The PNaCl toolchain is used to enable running the Native Client module directly from a web page...
Portable Native Client or PNacl, which is supported on Google Chrome at the moment, lets you compile and run native code developed in C or C++ within a secure sandbox in browser. PNaCl uses the LLVM toolchain to generate OS-independent and architecture agnostic intermediate bytecode which is later loaded, translated and executed by the browser. To get more information on PNaCl and it's less portable companion NaCl check the native client developer documentation.

Why Students Need the CppCat Code Analyzer
by Andrey Karpov
CppCat is a simple static code analyzer capable of detecting bugs in C/C++ programs. We started granting free academic licenses to all interested (students, teachers, and so on). For the sake of popularizing CppCat among students, I decided to write this post about errors that can be found in student lab work tasks posted at Pastebin.com...

Blaze, an open-source, high-performance C++ math library for dense and sparse arithmetic, released their new version.
Blaze 2.2 Released
After a total of five and a half months, a little late for SC'14, but right on time for Meeting C++, we finally release Blaze 2.2! But the waiting time was worthwhile! This release comes with several bug fixes and hundreds of improvements, many based on your hints, suggestions and ideas. Thank you very much for your support and help to make the Blaze library even better!
The big new feature of Blaze 2.2 is symmetric matrices. And this is not just any implementation of symmetric matrices, but one of the most complete and powerful implementations available. See the Blaze tutorial to get an idea of how symmetric matrices work and how they can help you prevent some inadvertent pessimizations of your code.

A status update for the work done on OpenMP for Clang/LLVM and future directions presented at the 2014 LLVM Developers' Meeting. The slides are also available here.
OpenMP* Support in Clang/LLVM: Status Update and Future Directions
OpenMP is a well-known and widely used API for shared-memory parallelism. Support for OpenMP in Clang/LLVM compiler is currently under development. In this talk, we will present current status of OpenMP support, what is done and what remains to be done, technical details behind OpenMP implementation. Also, we will elaborate on accelerators and pragma-assisted SIMD vectorization, introduced in the latest 4.0 edition of the OpenMP standard.
