[gsoc18] Mentor Search for Boost.Geometry idea
by Tinko Bartels 16 Mar '18

16 Mar '18

Hi, my name is Tinko Bartels, I'm studying to get a Master's degree in Mathematics at TU Berlin. I'm interested to work on Boost Geometry. I'm working at the university for a couple of years on C++ projects that rely on Boost libraries, most notably Boost.Geometry. Our work involves the computation of exact covers of spaces with boxes. This motivated my idea to add support to void union_(Geometry1 const & geometry1, Geometry2 const & geometry2, Collection & output_collection) void sym_difference(Geometry1 const & geometry1, Geometry2 const & geometry2, Collection & output_collection) void difference(Geometry1 const & geometry1, Geometry2 const & geometry2, Collection & output_collection) for Geometry1=Geometry2=box and Collection is a collection of boxes. Since I have no merged contributions to open source projects to refer to, I could, for example, provide an implementation of the difference method for types adhering to the box concept and a collection of boxes as output_collection. Since the results of those operations in terms of exact covers of the resulting space with boxes are not uniquely defined and the implementation should take less than 3 months, additional strategies for these specializations of the above algorithms could be added as future milestones. If this endeavor is considered worthwhile by potential mentors, I would get started on writing a proposal right away. Kind regards, Tinko Bartels -- Sent from: http://boost.2283326.n4.nabble.com/Boost-Dev-f2600599.html

Clang on Windows
by Egor Pugin 16 Mar '18

16 Mar '18

Hi, Based on recent news: Clang 6.0.0 is out with very decent support of the latest MSVC STL (15.6). Chrome is built with clang on Windows. So, maybe it is good time to include clang+windows into list of supported configs, setup a CI worker with clang (clang-cl) on Windows? Currently many boost libs already work fine, but some of them require small tweaks like explicit BOOST_USE_WINDOWS_H etc. -- Egor Pugin

Hi, I have shared the 1st draft of my proposal for "adding multicore and GPU computations to uBLAS" through the gsoc portal, but haven't yet gotten any feedback on it. Do I need to share it again on the mailing list too? Regards, Vardhan Gupta

[gsoc18] Student proposal reviewing (Internal process)
by madhur4127 14 Mar '18

14 Mar '18

Hi Boost Community, As per Submission template <https://svn.boost.org/trac10/wiki/SoCSubmissionTemplate> a candidate is required to show competency in C++ and must be "genuinely" interested in the project and also in open-source community. Judging of competency is straight forward, but how can interest be judged? Considering myself as example who had just got in serious open source projects(Sophomore Undergraduate). My coding ablilities <https://github.com/madhur4127/Programming-Competency-Test> are not at expert level but I am improving and learning myself while my university teaches knapsack greedy and automaton. Doesn't this gives an idea of interest in open source of a candidate or am I being a sophomore is a disadvantage with respect to other post graduate candidates? I know boost requires serious level work and it has world's most craftiest libraries but does Boost prefer experienced candidates or take chances with candidates genuinely interested in development and are moderately skilled? As per the division rules "A student must be able to write in C++". Regards, Madhur gsoc18 aspirant [Boost.Intrusive] -- Sent from: http://boost.2283326.n4.nabble.com/Boost-Dev-f2600599.html

[gsoc18] Boost.Detour & Mentor Search
by Michael Kiros 14 Mar '18

14 Mar '18

Hello, I'm a C++ developer and have been developing in C++ for over 6 years now in my personal time. I wanted to accomplish two things with this post: 1. Propose the idea of boost::detour 2. Find a mentor in the process Boost.Detour is not something new that I'd like to implement but a concept in programming that I have been using for a very long time now and would love to have it easily accessible with the inclusion of a simple <boost/detour.hpp>. The idea is to have function hooking easily accessible to everyone using C++. Though it may seem like a niche feature, function hooking is more commonly used than most people think (e.g. modifying binaries after compilation for feature addition, reverse engineering proprietary software). It's a beautiful concept when you see it working. In the process I need a mentor to guide me through the process of putting down my ideas to paper and implementing them according to the standards that Boost holds. This includes replacing components from my library with Boost concepts (e.g. boost::process). I'm also a student at Texas Tech University studying Computer Science. Can't wait to hear from someone. Michael
