Hi,I am fady faragallah 4th year student at faculty of computer engineering. I am interested in Boost.GIL and would like to contribute to the project. I have good experience in C++ programming and image processing algorithms and I am currently working on image processing and deep learning projects using convolutional neural networks. I need to know where I can deliver the competency test and how to contact the mentors. Thanks

Hello, I am Arnav Tiwari, a sophomore year undergraduate student of IIT Kharagpur. I am interested in working on Boost.GIL. I have prior experience in image processing and C++ so I feel I will be able to pick up the project and get to work quickly. I would really appreciate it if someone can point me in the right direction to get started. I hope I'm not spamming the mailing list, apologies if that is the case. -- Regards, Arnav Tiwari

Re: [boost] [variant2] Need rationale for never-empty guarantee

I would not expect perfomance differences on CPUs with branch predictor or if visitation translated into jump table (variant uses switch for this?). > For example, resizing a std::vector implements the strong guarantee that > state will be restored to before the resize if an exception is thrown in > the middle of the resize. Probably one should use different container type if a data types move/copy can throw. There even a vector implementation that will not copy/move on resize https://www.youtube.com/watch?v=Ke1mJiGO-pU (for CPU with virtual memory).

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
