by David Bellot 04 Mar '19

04 Mar '19

Dear Boost community, this year again, Boost C++ has been accepted as a mentor organization for the Google Summer of Code 2019. We are very happy to be part of this program every year because it brings talented students and a substantial amount of money to our organization to support our work toward the best libraries in C++. If you want to be a mentor, please propose your project now here: https://github.com/boostorg/boost/wiki/Google-Summer-of-Code:-2019 It's very important to write your proposal as soon as possible to attract the best students. If you have any questions, please contact me immediately. If you happen to be in Sydney, come and have a chat with me directly. Happy coding, David

Regarding project idea for GSOC 2019
by Syed Souban 04 Mar '19

04 Mar '19

Hi guys! I am a machine learning enthusiast looking forward to work in implementing some machine learning algorithms in c++ as a gsoc 2019 project. I know that a similar project has been done last year. So in a way I want to extend to that idea. I needed some suggestions and or pointers on which algorithms are feasible to implement. Regards, Souban

I am a 2nd year computer science student. I want to contribute to Boost.Intrusive as part of GSoC '19. I have some ideas to enhance Boost.Intrusive and also add more features to previous year's project in Intrusive. I am new to Boost. Any help regarding getting started with the library would be appreciated. Regards, Preet Thakkar

Re: [boost] Review request for variant2, review manager wanted
by Peter Dimov 03 Mar '19

> If anyone would like to step forward to manage the review, please do. Michael Caisse was the first to graciously offer his services (via Slack) and I'll be glad to have him manage the review. Thanks to Niall who also volunteered. :-) With respect to Niall's request for compile time and run time measurements, I've added a benchmark https://github.com/pdimov/variant2/blob/develop/benchmark/benchmark1.cpp and the results from compiling and running it on my machine are at https://github.com/pdimov/variant2/blob/develop/benchmark/benchmark1.md This is not a cherry-picked example that makes variant2 look good, so it loses to std::variant here and there. :-)

Here's what the config_info is: https://www.boost.org/development/tests/develop/developer/output/teeks99-te… I'm disappointed that we can't have general support for future versions of msvc. We don't seem to have this problem with pre-release versions of GCC/Clang. https://www.boost.org/development/tests/develop/developer/output/teeks99-02… Tom

Review request for variant2, review manager wanted
by Peter Dimov 28 Feb '19

28 Feb '19

I'd like to request a formal Boost review for the Variant2 library, https://github.com/pdimov/variant2. Variant2 contains an implementation of a variant<T...> type that is an almost conforming std::variant, except it doesn't require C++17 and supports C++11 and above. It's also never valueless and has a few other extensions. The same library also contains an expected<T, E...> type, which is like the proposed std::expected<T, E>, but supports more than one error type. expected<> is not yet production-ready and has no test suite, but I will finish it if the library is accepted. The documentation for the variant<T...> class is at https://pdimov.github.io/variant2/index.html. If anyone would like to step forward to manage the review, please do.

Hello all, I'd be interested in contributing towards Boost.Algorithm - what's the appropriate way forward? Or perhaps this question has already been asked somewhere and I'd appreciate if you could point me to the right place. Thanks

A Unicode library?
by Can Topal 28 Feb '19

28 Feb '19

Hello everyone, Since I regularly work with Unicode text, I have started to design a Unicode library for handling UTF 8,16 and 32. The current support in C++ is still limited. Mainly I'm trying to implement a STL like support for file reading/writing, I/O operations and memory storage. So a user could read/write and process Unicode text like an ASCII string without knowing how the text is encoded. I thought people might have use for it. Even though libraries like ICU exist, they aren't beginner friendly and I couldn't find one with decent support for I/O. Is there demand for this? And if so do you guys have any suggestions? Thank you. - Onur

[GSOC19] [GIL]Image processing algorithms
by Shardul Parab 27 Feb '19

27 Feb '19

Hi! I am Shardul Parab, a computer science student from the Birla Institute of Technology and Science, Pilani. I am highly interested in contributing to Boost via GSoC 2019 and would love to contribute to the GIL library(as per the project idea listed). I believe that I have good practical experience of image processing techniques and if given the opportunity would be a great learning opportunity too. I have a decent experience with the library and would like to ask as to whether there is any particular task that I could begin with for the project and begin contributing from now itself under the guidance of a mentor. Thanking you, Regards. Shardul Parab

[GSOC2019][uBLAS] Linear and Multilinear Algebra with Matrix and Tensor Computations
by Ashar 27 Feb '19

27 Feb '19

Hi, I am Ashar Khan, a Second Year Computer Science Student from India. I would like to work with boost for Summer of Code 2019 and improve on the existing *boost.uBLAS *library. I have completed the Programming Competency test of uBLAS and find myself perfect for the task. I am looking forward to a mentor who can help me in the later parts of the project. I request any Potential mentor of uBLAS (David Bellot, Stefan Seefeld, and Sem Bassoy) to help me start my work. You can check my programming test on the following link here <https://github.com/coder3101/gsoc19-boost-test> Any Suggestions and opinions on the test are welcomed. Sorry if I did wrong by open-sourcing my test. I did not find any specific instructions as to how to submit the test. Looking forward to hearing from you soon. Thanks and Regards Ashar
