Google Summer of Code 2018
by David Bellot 20 Jan '18

20 Jan '18

Dear Boost community, once again this year, we will apply to be a mentoring organization for the Google Summer of Code 2018. Our organization has been quite succesful for the last decade and this year we hope to be selected again. As part of filling in our application for 2018, we must supply to Google a list of potential GSoC mentors and potential GSoC projects for summer 2018 in order to be approved as an organisation this year. Therefore a lengthy page of awesome project ideas at https://svn.boost.org/trac/boost/wiki/SoC2018 before *January 23rd* would be an enormous help to getting us approved again this year and bringing to Boost another Google funding (worth dozens of thousands of dollars on average). If you think yourself able to mentor a student doing some work on Boost this summer, *please* consider adding a description of the proposed work item and your name to the list. If you want to have a better chance receiving funding for your project ideas, it is better to find good students early and that is best done by getting project ideas floated *early*. If you want to know more about mentoring a Google Summer of Code funded student work before you nominate yourself, please feel free to ask on the main Boost developers mailing list boost(a)lists.boost.org or via gsoc-admin(a)boost.org. Thank you in advance for your time. Finally, I would like to thank Niall Douglas, our previous Boost admnistrator for GSoC, who did an awesome work during many years and helped the Boost community grow thanks to all the funding we received years after years from Google. Best regards, David

Fwd: Re: [gsoc18][ublas] Proposal to add advanced matrix operations
by Mike Gresens 20 Jan '18

20 Jan '18

Hi Mike, Apart from the operations I was proposing, the idea of solving polynomials via QR reduction seems a great idea to me. I can add this module in the list of operations to be added to Boost.ublas in my proposal. I am looking for someone to mentor me on this project.

I have strong programming experience in C++ through internships, self projects and programming events. I wish to be a part of gsoc18 under boost and am particularly interested in the linear algebra library Boost.ublas. The ublas library can be made more useful for Machine Learning applications like recommendation systems, clustering and classification, pattern recognition by adding some operations required in those. I propose to add advanced matrix operations to ublas including - 1. Triangular Factorisation (LU and Cholesky) 2. Orthogonal Factorisation (QR and QL) 3. Operations to find Singular Value lists 4. Eigenvalue algorithms 5. Singular Value Decomposition (SVD) 6. Jordan Decomposition 7. Schur Decomposition 8. Hessenberg Decomposition This is a very brief description of what I would like to propose. Any suggestions that help in refining the requirements before making a draft proposal would be great.

[geometry][gsoc2018] Similarity between geometries
by Xing GUO 20 Jan '18

20 Jan '18

Hello, My name is Guo Xing, I have sent a mail for some ideas on gsoc18 projects. David's uBLAS project on GPU computation is a little bit hard for me. Still thanks for his kind reply :) . These days, I found a project that I could possibly work on. So, I decide to take "Similarity between geometries". Below is my short self-introduction. Name: Guo Xing University: Southeast University Major: Electronic Engineering Email: higuoxing(a)gmail.com Github: https://github.com/higuoxing Homepage: https://higuoxing.com Availability: (Feb-Jun 4 hr/day) (Jun-Aug 6hr/day or more) As for my code competency, I will take the project 1 competency test after my final exam. Thank you! Regards, Guo Xing

[callable_traits] Incorrect newlines in git
by Andrey Semashev 20 Jan '18

20 Jan '18

Hi, I've created this PR to fix newlines and tabs in Boost.CallableTraits: https://github.com/boostorg/callable_traits/pull/170 Without it, I cannot update my local Boost tree because git treats the files are modified. Could someone, please, merge this PR? It's really annoying that the update process breaks every time. Thanks.

[gsoc18] Implement HTTP Library
by Xing GUO 19 Jan '18

19 Jan '18

Dear community: I'm Guo Xing, who is currently a student in his third year of college(bachelor's degree). I have interests in web development. I've done some projects with Python and node before. I want to do some work with C++ in GSoC18. So, is there any ideas for me? Or, someone could be my mentor? I love open source, but never contribute to them. I want to do some contribution. Regards, Guo Xing https://github.com/higuoxing

crypto hash library
by kerukuro 19 Jan '18

19 Jan '18

While boost::hash and the proposed additions and are good for generic hashing, its API is not very suitable for cryptographic hashes and XOFs. Would there be any interest in boostifying this library eg under name 'boost::digest' and putting cryptographic hashes in there? https://github.com/kerukuro/digestpp

[gsoc18] R-tree serialization
by Kirill Mishchenko 19 Jan '18

19 Jan '18

Hi, My name is Kirill. I’m interested in the contribution to the project “R-tree serialization”. The search through the mailing list archive has shown there was an interest in this project among students in 2017, but as the GSoC 2017 archive site displays there was no student that participated to accomplish this project. Is it possible to work on this project as a GSoC 2018 participant? It seems like last year Adam Wulkiewicz was ready to be a mentor for the project. Briefly about myself. I am a PhD student working on Computational Humor. More precisely I’m working on the problem of finding/generating a humorous response given a textual input. My C++ programming experience includes a summer internship at Yandex Search and my contribution to mlpack (a machine learning library written in C++) as a GSoC 2017 participant (https://summerofcode.withgoogle.com/archive/2017/projects/4812231682293760/ <https://summerofcode.withgoogle.com/archive/2017/projects/4812231682293760/>). For mlpack I designed and implemented cross-validation and hyper-parameter tuning modules with significant usage of C++ metaprogramming. Best regards, Kirill Mishchenko

mingw and windows.h
by Raffi Enficiaud 18 Jan '18

18 Jan '18

Hi all, I recently pushed something for boost.test on develop that is apparently breaking the builds on mingw: http://www.boost.org/development/tests/develop/developer/output/igaztanaga-… What I do in the code is this: ---------- #ifdef _WIN32 #include <Windows.h> #endif ---------- and then later ---------- #ifdef _WIN32 class setcolor { protected: void set_console_color(std::ostream& os, WORD *attributes = NULL) const { DWORD console_type; /// some additional windows specific code #endif ---------- I thought that this would be enough for having the windows specific code, but apparently mingw disagrees with the error that some windows specific define is not there. Is this an issue with the code, the SDK, the machine? I have no experience with mingw, but if we are able to include windows.h, then we have to have the defines there (the missing macro is there since Windows 2000). Thanks for the help, Raffi

Change Trac wiki permissions
by David Bellot 17 Jan '18

17 Jan '18

Hi, does anyone have access to the boost Trac wiki. I need to change permissions on a page to allow users to edit the page as well, but I can't find any option. There should be an Admin button next to the Search button but it doesn't appear. The page in question is the Google Summer of Code 2018: https://svn.boost.org/trac10/wiki/SoC2018 Thanks David
