The thorough seeding of the list with defunct examples (BeOS, Mac OS < X) gives off a weird vibe.

There's also the standard halo effect listing. Any sufficiently large company is using a language / methodology / philosophy / technology you've heard about. And they're being namechecked on that language / methodology / philosophy / technology's website.

The classic is Microsoft.

Did you know Microsoft uses Scrum? They do!

Did you know Microsoft uses ISO 9295-424:54 (Humungo Software Dev Standard Written by the SEI, the DoD and a committee of 200 researchers from different Fortune 50 companies)? They do!

(Hint: Microsoft doesn't have a single unified method of development, it's largely up to each section to decide how they do the work)

View on HN

BeOS is interesting partly because of how it limited use of C++. C++ was the only supported API for userland, but the kernel was C.

Found a reference: "Creating a driver on BeOS is done using ANSI C; the C++ language requires certain support which is not available in the BeOS kernel environment." http://testou.free.fr/www.beatjapan.org/mirror/www.be.com/ab...

I remember another newsletter article where one of the devs described techniques for getting C++-like power while remaining within C (heavy use of function pointers in structs, that kind of thing).

Another: http://www.haiku-os.org/legacy-docs/benewsletter/Issue4-51.h...

The BeOS userland api had base classes with reserved functions that were there solely to reserve space in the objects vtable becase of the fragile base class problem:

I wonder how modern C++ frameworks are handling this?

I think it's simply an old list...if you look modern OS X stack traces, you often see C++ names in various frameworks. Random ones I found in `Console.app` (sadly this is a rather new & stable system):

> TCharStreamCFString::~TCharStreamCFString() + 37 (CoreText) [0x7fff9454b091]

> JSC::BlockAllocator::blockFreeingThreadMain() + 90 (JavaScriptCore) [0x7fff950fad0a]

> CA::Render::Server::server_thread(void) + 403 (QuartzCore) [0x7fff8c6e435b]

> TFSInfo::FetchProperties() + 1274 (DesktopServicesPriv) [0x7fff93a7da20]

> 0x000000010b50afca ld::tool::InputFiles::forEachInitialAtom(ld::File::AtomHandler&) + 410

Same on iOS...

> CoreMotion 0x043d60a2 CLMotionCore::runMotionThread(void) + 1016

I think I even saw a core part of NSAutoreleasePool in there once. I have never read the public Apple source tarballs, but from just seeing stack traces every now and then, it seems as if Apple is very happy with using both Objective C and C++ (the compiler makes this easy of course - e.g. C blocks have support for C++ construction/destruction etc...).

Almost the whole Objective-C runtime is C++ these days, although really more like C with occasional use of C++ features.
