From the desk of an author going by the name Pubby, a nice short article showing off "yield return" using Boost's coroutines library:
Multi-step iterators using coroutines
by Pubby
Note: The short article is serious. The author's favorite image, maybe not so much.

Scott Meyers' work on his new "Effective C++" book, tentatively titled Effective Modern C++, progresses with an updated draft item:
Declare functions
noexceptwherever 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
noexceptwhenever possible." Some people appear to be concerned that this could be misconstrued as advocatingnoexcepteven 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: ...

[For very new programmers, this is a basic review of the control flow language features available in C++ -- most of them also valid C, but at our request now with coverage also of the C++-specific range-for loop. -- Ed.]

New on Dr. Dobb's:
The Mixed Blessings of Compatibility
by Andrew Koenig
From the article:
Last week, I discussed the social pressures against changing the behavior of any system, even if the change is an improvement. I want to continue that discussion by exploring the implications of C++'s intent to act as an extension to C.

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.

Quick A: Yes.
Today on SO:
Move constructors and
std::arrayAccording to N3485 §23.3.2.2:
(...) the implicit move constructor and move assignment operator for array require that
Tbe MoveConstructible or MoveAssignable, respectively.So,
std::arraysupports move semantics if the type of its elements does. Great!However, what does this really mean? I tend to picture this type as a safer version of an array providing an STL-compliant interface but, if this is true, then how can an
std::arraymove-construct its elements? Can I do the same with an ordinary array?

Peter Sommerlad on C++11 and C++14 Standard(s) and Standardization
Created by Peter Sommerlad March 6, 2014
From the presentation:
Why is C++ in again?
• more computing per Watt!
• mobile - battery powered
• servers - cloud computing
• high-performance computing & GPUs
• better abstractions than C
• without performance price (e.g. of a VM)
• embedded (higher-level type safety)
• security (buffer overruns, pointers)

Scott Meyers' work on his new "Effective C++" book, tentatively titled Effective Modern C++, progresses with an updated draft table of contents and sample Item available:
Book Report: New Title, New TOC, New Sample Item
by Scott Meyers
Highlights from the article:
I recently finished the 32nd Item for the book, thus giving me drafts of five full chapters. The math still shows that about 40 Items will fit in the book's allotted 300 pages, so yesterday I took a hatchet to the prospective table of contents and chopped the number of Items down from 51 to 41. (Why 41? Because I have a feeling that one of the Items I've written will eventually get jettisoned as not being important enough to make the final cut.) Here's the current draft TOC....
[Table of Contents -- read it, just the titles give useful guidance]
... The most recent Item I wrote was "Distinguish
()and{}when creating objects." I blogged about one aspect of this topic here, and I thought you might be interested to see what I came up with. I've therefore made the current draft of this Item available, and I welcome your comments on it. Like almost all Items I've written, it's too long, so I'm especially interested in suggestions on how I can make it shorter, but I welcome all suggestions for improvement.

String's Length
by Andrzej Krzemieński
From the article:
Let’s start with a small test. Is the invariant expressed with the following assertion correct?
void test_length(std::string const& s) { assert(s.length() == strlen(s.c_str())); }It is not; otherwise I wouldn’t be mentioning this in the post; but do you know why it is wrong? ...

A few weeks ago the C++ committee did meet in Issaquah, its most important result: the final draft for C++14. See Herb Sutters trip report for details, I have written an overview based on his trip report, clangs C++14 status page and of course the papers it self.
Looking at C++14
by Jens Weller
From the Article:
As I have read through most papers of last and this year, a short overview which papers now have made it into the standard. So, what are the new features of C++14? Already before the last meeting, clang had implemented all known C++14 features of the draft published after the Chicago meeting.
