Herb Sutter presents the C++ Core Guidelines and demonstrates static analysis tools designed to enforce lifetime and memory safety by default.
cppcon.org — Presentation Slides, PDFs, Source Code and other presenter materials are available at: github.com/isocpp/CppCoreGuidelines/blob/master/talks/Sutter… -- Modern C++ is clean, safe, and fast. It continues to deliver better and simpler features than were previously available. How can we help most C++ programmers get the improved features by default, so that our code is better by upgrading to take full advantage of modern C++? This talk continues from Bjarne Stroustrup’s Monday keynote to describe how the open C++ core guidelines project is the cornerstone of a broader effort to promote modern C++. Using the same cross-platform effort Stroustrup described, this talk shows how to enable programmers write production-quality C++ code that is, among other benefits, type-safe and memory-safe by default – free of most classes of type errors, bounds errors, and leak/dangling errors – and still exemplary, efficient, and fully modern C++. Background reading: Bjarne Stroustrup’s 2005 “SELL” paper, “A rationale for semantically enhanced library languages," is important background for this talk. -- Videos Filmed & Edited by Bash Films: BashFilms.com Work at Hudson River Trading (HRT): tinyurl.com/safxfctfWhy it's here
6 people recommend this, 1 disputes itWhat people say. Engineers reference this talk for its early demonstration of lifetime-checking static analysis in C++ and discussions on memory safety.

We should be seeing completely safe C++ code soon. Take a look at Herb Sutter's CppCon talk this year: link to this video Reinventing the wheel isn't entirely necessary. Though if you're a SysAdmin and you write your codebase in Rust.. that's some nice job security. ;)

On “Rust Lifetimes”
At this year's CppCon Herb Sutter the chair of the ISO C++ committee addressed just this issue of lifetime safety. Here is a video of his talk and includes a demo of the upcoming static analysis tool that can do this with very minimal annotations link to this video I remember thinking when watching the talk that this was a very bad day for Rust as C++ could now do most of what Rust was promising

Take a look at Herb Sutter's talk from CppCon 2015. The slides are here ( link ) and the video is here link to this video . Microsoft will be releasing the static analysis tool as a free cross-platform tool (and I think open-source IIRC). They shipped a preview for Visual Studio 2015 with Update 1, and are planning on shipping a cross-platform version soon. As tools like this become free and ubiquitous, it will greatly improve C++ code safety.

…hen you're supposed to do an intro course to C++): "CppCon 2015: Kate Gregory “Stop Teaching C"": link (But again, I want an open wiki/live tutorial, along the lines of "How I start", but longer, which goes through all this stuff. We really should make one, both for C++14 and for C11). CppCon 2015: Herb Sutter "Writing Good C++14... By Default": link to this video Is also rather uplifting, and: CppCon 2015: Sean Parent "Better Code: Data Structures": link makes a pretty good case for simple, modern C++ being clear, easy and efficient.

> you can see C++ adopting pretty much the borrow checker as a tool - see Herb Sutter's talk at CppCon 2015 - link to this video . I have a lot of questions about this tool, both in terms of soundness/expressivity (how do you deal with shared_ptr and similar things if your goal is to statically guarantee no-alias on function entry) and in terms of practicality (the massive subsetting it requires basically makes ISO Core C++ an entirely new language). Also, Herb's claims about the ISO Core C++ lifetime profile requiring fewer annotations than Rust were incorrect. I gave basically this exact answer last time you posted a variant of this same comment on the last Rust thread.

On “C++ Core Guidelines”
Sure. That was kind of my point. Still, as Herb Sutter asked at CppCon 2015: "How many of you have your own homegrown string types at your companies? ... Don't lie. ... Right. And those of you who didn't put up your hand and are just bashful, ... we know we have them." 1 1 link to this video

On “Ask HN: C, C++, or Rust which language to learn next?”
…s. Rust is interesting, but I think it will remain an interesting language outside the mainstream without any major commercial backers (Mozilla does not count). In addition, C++ is taking a lot of the ideas from Rust and incorporating them along with tooling that will provide 95+% of the value of Rust while still keeping the advantages of C++ (see link to this video ) What is interesting with C++ is that although a lot of vendors are pushing their own languages - Microsoft with C#, Apple with Swift, Google with Go, Facebook with Hack, Mozilla with Rust - they are all deeply involved with C++ because C++ powers their mission-critical code. Another way of putting it would be that despite all the promotio…

If it was that easy. CppCon 2015, Herb Sutter's talk about writing safe code in C++14, just check how many in the audience use such tools. link to this video A tiny 1%, this on the conference of with many of the top C++ developers. Now imagine how little they get used on the typical enterprise environment, specially worse with C, that lacks many of the C++ added safety layers.

…king will allow you to pretty much get the same memory safety in C++ using unique_ptr and shared_ptr and const. The difference is that the compiler makes you think about it in Rust. Much like Scala inspired the adoption of features for Java, you can see C++ adopting pretty much the borrow checker as a tool - see Herb Sutter's talk at CppCon 2015 - link to this video . As the experience with Scala shows, the adopted features of the establishe…

I don't believe it is, unless something's changed. To quote MSDN: "The package currently contains checkers for the Bounds and Type profiles. Tooling for the Lifetime profile demonstrated in Herb Sutter’s plenary talk (video at link to this video ) will be made available in a future release of the code analysis tools." link
