[config] Supporting newer compilers: what does it take?
by Olaf van der Spek 22 Jan '18

22 Jan '18

Hi, What does it take to support new compilers, especially MSVC? 15.6 Preview 1 has been released now. Is some documentation or policy regarding test runners etc available? https://blogs.msdn.microsoft.com/vcblog/2017/12/19/c17-progress-in-vs-2017-… Gr, -- Olaf

[bjam] Can I disable a test based on an environment variable?
by James E. King, III 21 Jan '18

21 Jan '18

I'd like to disable some serialization tests if I am running a ubsan build on travis. Is there a way in the Jamfile I can make it conditional on an environment variable, or should I define something like BOOST_DATE_TIME_UBSAN and put "if !defined" in the appropriate tests?

[gsoc2018] Dynamic Shortest Path Tree
by a.i＠acm.org 21 Jan '18

21 Jan '18

Hi, I am Donghyuk Kim, a Ph.D. Student at Korea Advanced Institute of Science and Technology. I tried to contribute something last year but was not able to start the project for some reason. So I am about to re-try again this year. What I would like to contribute is a specific algorithm, "Dynamic Shortest Path Tree" which is simply, a dynamic version of Dijkstra's algorithm. It is a tree-based data structure to maintain single-source to all destination shortest paths and known to outperform Dijkstra or A* where the insertion and deletion of vertex/edge frequently occur. The concept of "Dynamic Shortest Path Computation" was originally introduced in [Fully Dynamic Algorithms for Maintaining Shortest Paths Trees] by D. Frigioni, et al. (http://dl.acm.org/citation.cfm?id=338900) I have already implemented a working prototype for my research, but unit test, coding style unification, and much more c++ style modifications are required for the general purpose. I hope someone finds it interesting and be a mentor on this journey. Thanks in advance.

[gsoc18] SafeFloat proposal
by Damian Vicino 21 Jan '18

21 Jan '18

Hi, I added a proposal to get SafeFloat ready for review: https://github.com/boostorg/boost/wiki/Boost-Google-Summer-of-Code-2018#3-b… This was a project I started in gsoc2015 as student mentored by Robert Ramey. Please contact me if you are interested in further details. Best regards, Damian Vicino

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
