Hi Everyone, I'm Tanuj Kr Aasawat, a final year student of Information Technology (B.E.). I would like to work on implementing a graph container with at least the following features: size, insert, delete, bfs and dfs. In the later part, would like to work on optimising bfs, using parallel computing techniques. In recent years, we have seen that major research is going on optimising the search operations for real world graphs (including RMAT graph and LiveJournal graph). Anticipating positive reply from your side. Thanks and Regards, Tanuj Kr Aasawat Deptt. of I.T, Jadavpur University, India Mitacs Globalink Research Intern, University of British Columbia, Vancouver, Canada

Gsoc 15 application (boost.uBLAS)
by siddharth kumar 19 Mar '15

19 Mar '15

Hello, I am Siddharth, a Computer science student from IIT Guwahati. After doing a bit of research over the project ideas, I have found the idea of further developing boost.ublas library interesting and so I have written the competency code. Here is the link to the code: https://github.com/sid6641/boost.uBLAS-Gsoc.git I have done a basic course on Linear algebra and Discrete Mathematics, so such a project suits my needs. I need a little help for proceeding further. 1. how is the error handling done in boost library. I am using assert for error handeling (but it does not sem the right way to me), the gaussian elimination doesn't work on singular matrices. So, I would like to set the errno and display apt message to the user when a singular matrix is the input. 2. Is there any predefined format for testing codes in boost library. I have done manual testing. Sorry, I am not familiar with most of the code in boost library. Any further helpful resources are welcome. p.s. I have started writing the proposal for the project and I'll soon draft it for review. Thanks, Siddharth

Boost on Android
by Dmitry Moskalchuk 19 Mar '15

19 Mar '15

Hi all, As someone of you already know, we've started regular regression testing of Boost on Android. After some (bit longer than I expected) time of debugging, we finally made it working in automatic mode so you can see our results of Boost testing on http://www.boost.org/development/tests/develop/developer/summary.html. We also automatically publish Android-only testing results on https://boost.crystax.net/master/developer/summary.html and https://boost.crystax.net/develop/developer/summary.html. Currently, we have numerous of fails. Some of them are bugs of Boost libraries, some - bugs of CrystaX NDK. We're strongly aim to continue support Boost on Android and fix our NDK to make Android as POSIX-conforming as possible; however, it's not easy to review all fails and distinguish NDK bugs from Boost bugs. So we're asking Boost libraries authors to start looking on Android regression testing results and file tickets to our tracker (https://tracker.crystax.net/projects/ndk) if it become clear that root of fail is bug of CrystaX NDK. CrystaX NDK is open-source project started as my personal project in 2009 to add C++ support to the Google's Android NDK (Google published first Android NDK release in 2009, and there was no support of C++ at all). My patches were published immediately but Google have added the same level of C++ support two years after first CrystaX NDK release, being constantly requested within two years to do that by Android developers community. To that time CrystaX NDK was much more than just "Android NDK with C++ support". Nowadays CrystaX NDK differs very much from Google's one - mostly because Google isn't interested in evolving of native development for Android; but we're _very_ interested. Our main goal is to create powerful comprehensive toolkit for native development for Android, and in fact we're making it much better than Google do. We're strongly aim to continue working on CrystaX NDK and support Boost on Android - just because it's helpful to our NDK too, not only to the Boost community. However, since CrystaX NDK is fully open sourced and we're working on it without being paid by any organization, we need help from peoples interested in evolving of native development for Android. Since 2009 I was working on the project in partial time fashion, making money other way (being paid contractor and working on many commercial projects); but last eight months we have switched to the full time scheme, and have achieved significant results in last release. Now we want to continue working on it full time, improving it more and more, and making native development for Android easier. We've started fundraiser on https://www.bountysource.com/teams/crystaxndk/fundraiser to collect funds needed for us to continue working on CrystaX NDK full time. We're calling everyone interested in Boost-on-Android to help us - either by sponsoring us or providing contributions to our project. I hope I did not violated rules of this mailing list because my message is directly related to the Boost development. We just want to make both CrystaX NDK and Boost better. Some links: https://www.crystax.net/android/ndk - CrystaX NDK project page https://tracker.crystax.net/projects/ndk - our bug tracker https://www.crystax.net/contact - here you could contact us directly -- Dmitry Moskalchuk

Hi I'm a graduate student of Northwestern Polytenical University in China. Just as listed in the web,based on the proposal requirement of 'Boost Documant Library development' ,we should copy and past a programming test at the end of the proposal.But i'm not sure,do you just need the result picture or the all code. Thank you Best Regard Jianwei Li

GSoC2015
by raul lopez turcios 19 Mar '15

19 Mar '15

Hello, I wish to apply to the GSoC program, i have already read the wiki, and i'm currently working in a proposal. I just wanted to make a few questions as this is my first time applying for Boost Libraries and GSoC in general. First of all, i would like to know how much of a chance one gets as being "starter" working on boost. Second i would like to know if there is a way for someone to check out my proposal to see if i could improve anything, or should i just ask a teached in regards to that. And also i would like to know if any code i had already made in C++ is valid to be added to the proposal, or if there is anything else to improve your chances to be selected. Thanks for yor time.

[gsoc] Suggestions on Proposal for Boost Document Library Project
by Anurag Ghosh 18 Mar '15

18 Mar '15

Hello Everyone I'm Anurag Ghosh, a 2nd year undergraduate student studying in IIIT-Hyderabad, India and I'm interested in making the Boost Document Library as a part of the Google Summer of Code 2015 Program. My proposal document can be viewed at https://github.com/anuragxel/boost-generic-document-library/wiki/Google-Sum… Kindly provide me with comments on the project proposal, as it may seem I have missed out on something or the other. I'm hopeful that a discussion would be very helpful in enriching my proposal. Also, I have developed a working prototype (only for OpenOffice/LibreOffice API currently) for this project (given as a competency test) whose code is hosted at https://github.com/anuragxel/boost-generic-document-library/ Also, Kindly suggest any changes as may deem fit to the code, I will make the changes appropriately. Thanks Anurag Ghosh (anuragxel)

Could you please provide code for one or more return-by-value test cases that fail because the value gets normalized? I'm really hesitant to change anything without having test cases to work with. That would also help with documenting the specifics of the problem. Thanks, --Beman

[boost.ublas] [gsoc'15]
by Dhruv Kohli 18 Mar '15

18 Mar '15

Hello, I am Dhruv, majoring in Mathematics & Computing from Indian Institute of Technology, Guwahati. After doing a bit of research over the project ideas, I found the idea of further developing boost.ublas library interesting and have started writing the programming competency code. Here is the link to the code I've written yet: https://github.com/chiggum/boost.ublas/blob/master/gaussian_elimination.hpp. Though the code is not yet complete, but a naive version of algorithm is implemented and is integrated into ublas. To me, the code seems to be running properly. I need a little help for proceeding further. 1. Can someone please direct me to some code snippet that shows how the error handling code is written in boost library. To be specific, the gaussian elimination doesn't work on singular matrices. So, I would like to set the errno and display appropriate message to the user whenever a singular matrix is given as an input. 2. What sort of test code is required? Do we need to have a test case with hard-coded output to be checked against the results obtained when the test case is passed to the algo. Or there's some other predefined format for testing codes in boost library. Sorry, I haven't yet gone through most of the code in boost library. Any further helpful links/resources are welcomed. Thanks & Best regards, Dhruv https://github.com/chiggum P.S. Sorry for reposting the mail. I am still waiting for a reply.
