Fwd: [gsoc18] Boost.Detour & Mentor Search

---------- Forwarded message ---------- From: Michael Kiros <michaelakiros(a)gmail.com> Date: 15 March 2018 at 02:30 Subject: Re: [boost] [gsoc18] Boost.Detour & Mentor Search To: David Bellot <david.bellot(a)gmail.com> Hi David, I have written the draft of a proposal to add a new library (or work on it during the Summer of Code 2018). It's a proposal for the addition of Boost.Hook, a function hooking and control flow augmentation library. It's something I've worked on a lot in the past and would like to incorporate into Boost so that both I and others have a centralized, agreed way of taking an approach to function hooking. I also have plans of integrating it with Boost.Process and some memory mapping libraries from Boost so that there are fewer "third-party dependencies". Here's a link to the draft: https://drive.google.com/file/d/1nh436adVvIHC_ AXTAJi6Wr_uLpM4-SSc/view?usp=sharing I would really like to know the feedback to this and if anyone's interesting in mentoring me during the build up of this project. It's a very interesting, useful topic. I can assure anyone that.

[gsoc18] Project proposal for Boost.Geometry (set operations on boxes)
by Tinko Bartels 22 Mar '18

22 Mar '18

Hi, one week ago I posted a mail searching for mentors for a Boost.Geometry idea about implementing the basic set operations (difference, union_, sym_difference) for <box,box,Collection<box> and I was happy to see interest voiced by Vissarion and Adam. I have now completed my proposal with a slightly extended version of that idea and I'd be thankful for any comments: https://docs.google.com/document/d/1gNtqTbkDVXp9dPCRZZut4bBgjvQwJNdoV-EJOrE… I've also improved my proof of concept/self-designed competency test, added a check for correctness and committed it to the github repository: https://github.com/tinko92/boost_geometry_difference_demo It now includes a patch for the boost_1_66_0 source tree, that allows tests of that implementation with the proper call: boost::geometry::difference(box1,box2,box_vector) (hopefully, if I didn't break anything I didn't see) without breaking it for other geometries. This was tested on GCC (main.cpp can be built if the folder tree from the repository is copied to some directory XYZ with the command g++ main.cpp -o main -IXYZ), VC9 and VC15. Thanks in advance for any comments on the proposal or the preliminary implementation of difference. Best, Tinko -- Sent from: http://boost.2283326.n4.nabble.com/Boost-Dev-f2600599.html

[gsoc18] Seeking a mentor for Boost.Geometry project 2: Nearly antipodal points distance accuracy improvement
by Adeel Ahmad 21 Mar '18

21 Mar '18

Greetings, Congratulations to the Boost community on being selected for GSoC 2018! I recently read through the project ideas listed on the Wiki page, I'm particularly interested in "Boost.Geometry Project 2: Nearly antipodal points distance accuracy improvement". I wanted to know if I should implement a particular algorithm for finding the shortest distance between two points? There are many options, such as the Haversine formula, Equirectangular approximation, and Rhumb line. Or, would any of these be fine? Additionally, could the mentor please let me know on how to share the code? I was thinking of creating a GitHub repository, this would make it easier for the mentor to provide feedback. Would that be alright? I was also a participant in GSoC 2017 with the OpenAstronomy organization. My project was to design and create a Python client for Hierarchical Progressive Surveys. It enabled users to view astronomical figures in an interactive environment. More details of the software package can be found here (https://hips.readthedocs.io/en/latest/getting_started.html) I look forward to your reply. Kind regards, Adeel

[gsoc18] Mentor Search
by Jimmy Beckett 21 Mar '18

21 Mar '18

Hello all, I'm a high school senior out of Texas (I've been accepted into an accredited 4-year college and am therefore eligible for GSOC.) I'm most interested in the uBLAS proposal, but any of the other proposals would be amazing to work on, along with any additional ideas any prospective mentors might have. I've completed the competency test for uBLAS ( https://github.com/jimmybeckett/gsoc18CodeSample) and I also have a lightweight big integer library that I've been working on recently available at https://github.com/jimmybeckett/BigInteger. It doesn't meet the 1000 loc requirement, but it should supplement my competency test. Of course, code reviews are always welcome! If any prospective mentors have project ideas to discuss or any comments to make, I would love to hear them! Thank you, Jimmy Beckett

[CircleCI] boostorg's plan has 8 days left on its trial
by Mateusz Loskot 19 Mar '18

19 Mar '18

Hi, I've been working on CircleCI configuration for Boost.GIL, temporarily, in my GitHub fork (mloskot/gil). When I go to https://circleci.com/gh/mloskot/gil/edit#parallel-builds, I see this message: "boostorg's plan has 8 days left on its trial. You may want to try increasing parallelism below to get the most value out of your containers." Could anyone help me to understand why I see this message even if I added the project to CircleCI from my fork and not from boostorg/gil? Does it mean, all boostorg repositories and all their forks share the CircleCI allowances? There is also second message saying "These settings are only for 1.0 builds. To define parallelism for 2.0 jobs" and since I'm developing CircleCI 2.0 setup for Boost.GIL, I assume I can ignore this secong message. Best regards, -- Mateusz Loskot, http://mateusz.loskot.net

[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

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

[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.

[gsoc18] uBLAS competency test
by Arun Ramachandran 11 Mar '18

11 Mar '18

Hello, I'm Arun, a final year computer science undergrad. I'm interested in working on project 1 of the uBLAS library (adding statistics and machine learning functions). I have experience with developing in C++ from working on Code Character (https://github.com/delta/codecharacter-simulator) an online AI programming challenge that some fellow students and I hosted. Since this is an application, I've taken the competency test for uBLAS and have implemented a small matrix library using expression templates along with some unit tests and benchmarks. The repo is currently private, so if a mentor shares their GitHub handle I can add them as a collaborator for reviewing it. Thank you, Arun Ramachandran

Hi, I am Varun Mehrishi, a third year engineering student from Manipal University Jaipur (MUJ), India. I am currently pursuing Bachelors of Technology in Computer Science and Engineering. I am most comfortable with C++(STL) and Python, and also follow the new and experimental features introduced in the new standards with additional help of cppcon and BoostCon. I also have interests in Data Science, Machine Learning. I wish to participate and contribute to Boost.uBLAS. I've read the project idea and description from the suggested GSoC project proposals. I am really interested in working on the project "Project 1 : Add statistics and machine learning functions" which is focused on extending Boost.uBLAS functionality towards statistics/ML. I have implemented a basic template version of the mentioned Programming Competency Test (basic-matrix-lib <https://github.com/varunmehrishi/basic-matrix-lib>) and used C++14 generic lambdas wherever necessary. Your feedback and suggestions will be extremely valuable as they will help me improve my implementation and add more functionality. Looking forward to your guidance -- With warm regards, Varun Mehrishi GSoC 2018 Aspirant

Re: [boost] How to set LDFLAGS in 1.66.0?

Using boost libraries does not prevent you to do so. One could either specify RPATH for your boost library files, application executable, or both. BTW, looking at your pasted output of ldd indicates that you've set your RPATH for wrong value, but that should not be boost specific; try googling without 'boost' keyword? 2018-03-09 9:59 GMT+09:00 Dean Anderson <dean(a)av8.com>: > Thanks for the reply. > > I'm not looking to find an external library, I'm trying to set the RUNPATH > on the boost shared libraries.

[foreach][polygon][xpressive][bimap][ptr_container][gil][assign][typeof][msm] PRs for removing executable attribute for files
by Edward Diener 08 Mar '18

08 Mar '18

The following libraries still have PRs, which I have previously submitted, for removing the executable attribute for one or more files: foreach polygon xpressive bimap ptr_container gil assign typeof msm None of these PRs affect anything other than the file attribute, so no testing is needed AFAICS since no code changes. If the maintainers of the above libraries, or someone else with write access to these libraries, can merge the appropriate PR to 'develop', and then merge 'develop' to 'master', we can get rid of having any files with their executable attribute set in the next release.

[gsoc18] Mentor Request for uBLAS (prefer support for tensors)
by HiImKarl 07 Mar '18

07 Mar '18

Hi, I am Karl, a financial engineering student that is very passionate about C++. I think my background in applied math and stats would make me a great candidate for writing a tensor library. I would also like to point to this header-only multi-dimensional array template library with compile time tensor rank that I've written in the past: https://github.com/HiImKarl/Tensors, which may be good groundwork. It is a little late into March, so I was wondering if there were any mentors still looking for students for this project. I have already completed the competency test. -- Sent from: http://boost.2283326.n4.nabble.com/Boost-Dev-f2600599.html

[gsoc2018] Project 1.1: Add statistics and machine learning functions
by Dattatreya Mohapatra 07 Mar '18

07 Mar '18

Hi, My name is Dattatreya Mohapatra. I am an undergrad at IIIT Delhi, majoring in CS. I am interested in working on extending the Boost.uBLAS library as a project. I have taken courses on Linear Algebra and Machine Learning in the past, so I have a decent basic understanding of the subject. I have used C++11 in several of my course projects, so I have some familiarity with advanced features like lambdas and template programming. I have gone through the earlier threads on the same, and have started working on the core-competency test (CCT). Can the mentors of this project please guide me as to how should I get the CCT reviewed when its ready? Also, is there anything else I should look at apart from the documentation which would be helpful? Thanks and regards, Dattatreya Mohapatra
