A vision of Boost
by David Sankel 21 Jul '17

21 Jul '17

I got involved with Boost in 1999. I was 17, attempting to learn C++, and saw a footnote in "The C++ Standard Library" that mentioned boost.org as a place where quality C++ libraries are found. For me, it was love at first sight. Automatic pointers? Amazing. 'std::array'? Fantastic. I've been using C++ and Boost ever since. Never in my wildest dreams would I have imagined that eighteen years later I'd be sitting on the C++ standardization and Boost steering committees. As I listen in the Library Evolution Working Group I imagine what it must've been like for Beman and Dave to sit in similar meetings and ask themselves "wouldn't it be great if there were an online place that collects freely available C++ libraries and offers a peer-review process for incorporation? It'd be hugely beneficial for C++ users and the C++ standard as well." People get involved in Boost for many reasons. Some think it'll improve the chances they get their library standardized (and it's true!). Some think it'll improve their consulting or job prospects (true as well!). Others hone in on particular aspects, such as the build system, the people, or individual libraries. All these reasons are great, but for me the key was Boost's mission: to improve the way people code. At first it was more about improving the way I code, but as time went on it became more and more about helping others. For me, this is something worthwhile; worth sacrificing for. Now there are pros and cons with moving Boost to CMake, but at the center of all steering committee discussions has been the Boost mission. "How is this going to help us reach more users?" "How is this going to help us reach more developers?" "How is this going to impact the standard and the greater C++ community?" We may have made the wrong choice (though I doubt it). We may have communicated it in a non-ideal way. However, one thing is for sure: We made the decision based on furthering Boost's mission. A mission I want others to fall in love with like I have. So, we're moving to CMake. And, yes, we'll get there together. Many questions still exist and we'll have to figure out the answers as a community. The stalemate, however, is now over. -- David Sankel

[outcome v2] ntkernel_category() custom error category appropriate for Outcome?
by Niall Douglas 21 Jul '17

21 Jul '17

I put together a custom `std::error_category` for NT kernel `NTSTATUS` error codes with error condition comparison support for both POSIX and Win32 error code spaces: https://github.com/ned14/ntkernel-error-category Question: Is this custom `std::error_category` so niche and unlikely to be useful to anybody that people would object to it being supplied in Outcome v2?

Hello, I'm Arnav. I came across Boost when going through the list of organisations that take part in GSoC. I found Boost very interesting, so can anyone guide me with how to proceed? Thanks!

[BB++] Now is 3.5x faster than Node.JS
by Phil Bouchard 21 Jul '17

21 Jul '17

Greetings, I am now using C++14 standards, the error reporting is all compile-time now and I get a test that is 3.5 faster than Node.JS! You can see it by yourselves here: https://github.com/philippeb8/root_ptr/tree/bb++/bbpp2cpp Furthermore there is no need for 'operator ->' anymore because the access operator is deduced at compile-time. Here is a code sample: int main() { int temporary = 1; auto foo = function () { return function (int argument) { return argument; }; }; for (int i = 0; i < 1000000; ++ i) cout << foo()(temporary) << endl; } Note that it's also possible to dynamically allocate function pointers like this: int main() { int temporary = 1; auto foo = new function () { return new function (int argument) { return argument; }; }; for (int i = 0; i < 1000000; ++ i) cout << foo()(temporary) << endl; } I will show you a clear example of cyclic references handling soon. Regards, -Phil http://bbplusplus.com/

MS controlled email domains - not going to work
by Michael Caisse 20 Jul '17

20 Jul '17

The irony in sending this message is that the people who need to see it probably wont get it. We are having trouble with hotmail.com, live.com, msn.com, and outlook.com. Microsoft is filtering the dedicated IP address used by the mail lists and most recently has responded with: Not qualified for mitigation [ip address] Our investigation has determined that the above IP(s) do not qualify for mitigation. These IP(s) have previously received mitigations from deliverability support, and have failed to maintain patterns within our guidelines, so they are ineligible for additional mitigation at this time. We have tried to explain multiple times that the IP address has a new owner but we seem to be stuck in almost an auto-response loop. We will continue to try and get service unblocked; however, I would recommend that you dump your MS controlled accounts for Boost mail lists and use another service. michael -- Michael Caisse Ciere Consulting ciere.com

Re: [boost] CMake announcement timing

The situation is difficult to handle now that the announcement has been made, other than to ask people to show temperance for the duration of the review, which ends next Monday (July 24th.)

I think it is very unfair to make the announcement regarding Boost and CMake while a review is ongoing. Surely the announcement could have waited until after the review period for mp11.

Introducing the Backbone++ Programming Language
by Phil Bouchard 19 Jul '17

19 Jul '17

Hello Boost, (The former language name is already taken by Microsoft) By taking advantage of the simplicity of the code of Javascript, the power of C++ and the deterministic C++ memory manager Root.Ptr, I decided to write my own programming language which takes advantage of all these powerful features. On the downside Javascript suffers from a slow garbage collector that kicks in randomly which makes it impossible to write real-time engines and C++ just doesn't have any objective memory manager up to this day. My initial attempt was to convert Javascript into C++ but then the principle of 'closures' and 'escape analysis' inlaid with Javascript just makes it impossible to get rid of the garbage collector. So if we sacrifice these principles away then we can integrate Root.Ptr and take advantage of the power of C++ and the true flexibility and run-time features of Javascript. It has to be noted that BB++ is an extension of C++ and therefore everything we can do in C++ can also be done in BB++ and vice-versa. You can find the source code here: https://github.com/philippeb8/root_ptr/tree/bb++/bbpp2cpp And the benchmarks indicate BB++ is 3 times faster than Node.JS! Note that the language is still in a preliminary state but we can already compare it. Furthermore, in theory, it should be possible to offer a service which compiles the executables for combinations of major architecture / OS only once, cache these executables on the webserver and executing them in a specialized container on the client's desktop. This or convert the file BB++ -> C++ -> WebAssembly. Thus, in theory, we would be able to execute real-time engines from within our own browser! So I am including Boost because the backend of BB++ is Root.Ptr and the benefits are inevitable at this point. You can see here an example of mixing BB++ with C++ code and how easy it is for the language to get rid of cyclic references: https://github.com/philippeb8/root_ptr/blob/bb++/bbpp2cpp/tests/input2.bb Regards, -Phil http://www.fornux.com http://www.finitetheory.com https://www.actatabula.com http://www.backbonepp.com
