A recently posted talk by BitTorrent's chief architect:

C++ in the 21st Century

by Arvid Norberg

From the announcement:

In this edition of Tech Talks: an overview of some C++ gems. I threw this talk together because my team was about to start a new project in C++11. Since it’s fairly new, I figured some of it might not be as well-known as it should. Fundamentally, I’m pretty excited about all the new possibilities in C++11. Even higher-level abstractions, at even lower cost than C++98.

In the video below, we go over for-loops, automatic type deduction, lambda functions and more.

Declare functions noexcept wherever possible? -- Scott Meyers

By Blog Staff | Mar 31, 2014 09:39 PM | Tags: None

Scott Meyers' work on his new "Effective C++" book, tentatively titled Effective Modern C++, progresses with an updated draft item:

Declare functions noexcept wherever possible?

by Scott Meyers

From the article:

In the comments following my last post, there was some controversy regarding the wording of my advice on noexcept functions. My advice is "Declare functions noexcept whenever possible." Some people appear to be concerned that this could be misconstrued as advocating noexcept even when it makes no sense, but I think the advice is a reasonable conclusion to the Item that supports it. I posted a draft version of that Item in early February, but I've revised the draft since then, and I'm making the current draft available now: ...









cereal 1.0.0 is available

By Blog Staff | Mar 28, 2014 11:08 AM | Tags: None

cereal 1.0 is available:

cereal - A C++11 library for serialization

cereal is a header-only C++11 serialization library. cereal takes arbitrary data types and reversibly turns them into different representations, such as compact binary encodings, XML, or JSON. cereal was designed to be fast, light-weight, and easy to extend -- it has no external dependencies and can be easily bundled with other code or used standalone.

... cereal uses features new to C++11 and requires a fairly compliant C++ compiler to work properly. cereal has been confirmed to work on g++ 4.7.3, clang++ 3.3, and MSVC 2013 (or newer). It may work on older versions, but there is no emphasis on supporting them. cereal works under both libstdc++ and libc++ when compiling with g++ or clang++.

CppDepend 4 Released

By James | Mar 27, 2014 04:01 PM | Tags: None

cppdepend-features.PNGCppDepend allows architects and developers to analyze a code base, automate code reviews, and facilitate refactoring and migration. It’s based on Clang for more reliability and lets queries the code base over LINQ queries thanks to CQLinq.

New features in CppDepend v4.0 include:

  • A new dashboard panel that shows the state of the current code base at a glance as well as a comparison to a baseline.
  • Monitoring trends on 50 default “Trend Metrics” as well as custom trend metrics. These can be displayed through Trend Charts.
  • Focus on recent rules violations (by using filters) that occur on code elements added or re-factored since a baseline.
  • Listing rules and queries according to common criteria, and quickly listing all violated rules.
  • Major UI enhancements and modernized menu organization.
  • Enhanced and redesigned reports include trend metrics charts and more information.

A follow up on my proposal series & C++14 post:

C++ Status

by Jens Weller

From the Article:

This is the followup I promised after my last series for Issaquah. The current status of the standardization is that C++14 is on its final way to become a new ISO Standard, as you can see on the C++ Status Page of isocpp.org.
