http://blogs.msdn.com/b/vcblog/archive/2015/04/29/c-11-14-17-features-in-vs-2015-rc.aspx[^]
I'm not quoting anything since all the interesting stuff is in a pair of tables; but the only incomplete C++11 items are expression SFINAE (no), constexpr (partial), and C99 preprocessor (partial). C++11 constexpr is footnoted as will probably be working before RTM, the preprocessor is unchanged from VS2013. Even after reading the standard proposal[^] and wiki article[^] I'm not sure WTE SFINAE is supposed to be about beyond that it involves the cluster elephant of C++ templates. Hidden in the faq is a comment that at the compiler level they're planning to release it as an VC2015 update instead of holding it for the next major release; but to avoid compatibility problems the STL won't be updated until later.
C++14 support went from 1/11(12 if you count an optional item) to 8/11 bullet points; and C++17 went from 1/10 to 4/10.
The C++14/17 standard library is complete except for 7 items waiting on constexpr to be fully debugged and one that's related to SFINAE.
Most of the updates are in the just released RC build; but a few were implemented between when that codebase was locked down and now, and won't be available publicly until RTM.
If anything in my attempt to summarize that's wrong I plead knowing just enough C++ to be dangerous. 
Did you ever see history portrayed as an old man with a wise brow and pulseless heart, waging all things in the balance of reason?
Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful?

SFINAE[^] itself is a concept that has been an important part of C++ since the use of templates was seriously explored.
It basically allows the compiler to consider any potential type for the creation of a template. If an error were to occur because of one of the potential substitutions, it will simply remove that from the list of candidates. As long as there is a valid candidate to instantiate the template no error will be emitted.
The "expression SFINAE" in the C++11 standard expands the compiler support to evaluate and consider certain expressions that are known at compile-time, and therefore should be able to be resolved by SFINAE.
IMO, this is a corner-case that will be nice when it's support appears, but it is by no means something that will be sorely missed by many.
constexpr on the other hand is one that I have been waiting for from VS for years.

Everything you said was accurate.
I assert that C, C#, JAVA, JavaScript and even C++ programmers know enough to be dangerous in C++.
I think the devs that are dangerous, are the ones that believe they have learned it all...
I'm pretty sure that's not you

I'll take a look at your article later; but thanks for the plain English short version. Unless I start doing crazy stuff with templates, that's probably all I really need to know.

I've got mixed feelings about the syntax similarities in that family too. Yeah it's nice that you can generally follow code in any of them if you know just one, and being able to jump in and bang out a few quick updates right away is convenient; but they all have enough gotchas to ambush the overconfident. And despite using it for most of the last decade I still wouldn't even claim to know all of C# Winforms programming; never mind WPF or the web bits.

Yes there are both pluses and minuses in making these languages have similar syntax. It requires discipline to learn and adopt the idioms of each. Often you can look at, say, C# code and tell whether the dev came from a C++ or VB background but, ideally, you shouldn't be able to.

IBM sees the future of quantum computing as having a major impact in the life sciences and chemistry fields. Sadly, all it shows are cat videos

Dead cat videos, or live cat videos? Or do I have to watch the video to find out whether that is dead or live?

And if you watch dead cat video, you will never know if you killed it by watching it

The very act of watching could change the state, so leave them unwatched.

The holographic headgear stole the show, thanks to a number of head-turning demonstrations and the unveiling of the Windows Holographic platform. Just wait until ... a certain industry ... gets their "hands" on it. Boom chicka-wow-wow

There are some things that a hologram cannot replace. Enhance perhaps, but not replace

Microsoft today announced Project Oxford, an evolving portfolio of REST APIs and SDK that will help developers build intelligent apps. "Tommy, can you hear me?"

Microsoft just demonstrated one of the intriguing possibilities that emerge from its single platform/multiple form factors approach for Windows 10: the ability to use your phone as your desktop computer. Really, really, really underpowered desktops
But I love the feature. It's about time.
|
|
|
|
|
Belfiore pointed out that the feature really shines when apps have been built to scale across form factors, so whether or not this ends up being a feature most would want to take advantage of really depends on developers committing their efforts to Windows 10.
Great, so in addition to writing websites that scale to mobile devices, now we need to write mobile apps that scale to desktop monitors.
I think I'm turning schizo, yes, I think I'm turning schizo...

When you sign up to a service with a telecomms company for your phone and broadband, you have an obligation to pay your bill every month. However, the company also has an obligation: to provide you with that service and react when something seems out of the ordinary. To be fair, AOL is *totally* worth it.

At its Build 2015 developer conference today, Microsoft announced Project Spartan will be called Microsoft Edge. Joe Belfiore, Microsoft’s corporate vice president of the operating systems group, announced the news on stage, and detailed Edge will have support for extensions. Very... edgy
I'll get my coat...

Not thrilling, but a nice conservative name.

...I would rather they just call it Spartan
