Re: [eigen] Call for survey questions

[David Tellenbach <david.tellenbach@xxxxxxxxxxxxx>]

Hi Christoph,

Is anyone currently working on this? Or willing to start working on it?

I've collected some questions mentioned in this thread. As already said I would set up the survey. However, some time has passed and I just didn't find the time. But it's definitely on my list and I guess I can at least present a first draft in July (since I'm a student my obligations are heavily changing from time to time). 

Another question which came up here:
http://eigen.tuxfamily.org/bz/show_bug.cgi?id=1687

 Is anyone using/setting/changing Eigen-preprocessor directives such as EIGEN_FAST_MATH?
More generally anything from:
http://eigen.tuxfamily.org/dox-devel/TopicPreprocessorDirectives.html

Thanks for the suggestions, going to add them to the list. 

An alternative (or addition) to the survey would be to comb through open-source projects and -- if they use Eigen -- try to automatically analyze things like what modules are used, what language standard is used, etc (depending on the thoroughness this is probably more complicated than doing a survey).

Thats an interesting idea. Do you think about crawling the major code hosting providers? The very different structure of individual project could make this very hard, though.

If someone wants to handle this survey, do you need help in any form? Or access to anything?

Regarding your idea above, is there a way to see where Eigen is used as a submodule? Any guesses if this is the main way of including Eigen into other projects?

Thanks,

David

Sub-question: Used in production/Only in legacy projects/Only for "toy-projects" -- but that sub-question could be asked for every question (and maybe makes the survey too complicated).

Hello together,
as discussed in another mail thread, this mail thread tries to gather questions that are suitable for a little survey among Eigen users and developers to find out how and with which tools Eigen is currently used and how and with which tools Eigen will be used in the future.
I think focussing on simple checkbox questions or questions that can be answered in one or two sentences is a good idea.
Cheers,
David
