Don't forget that the aim should be to provide a site thats both functional and EASY to use. I've briefly looked at Plone, and my first impressions were that while it seems to be extremely comprehensive and have loads of features, you could spend days learning how to configure it and it took a while to work out how a user should add content to it. Admittedly I didn't spend that long on it, and it might be possible to configure things to make it easier. One of the main advantages that I can see in a Wiki is that it's relatively familiar to people, and in some respects is "self maintaining", in that it doesn't require dedicated admins to look after it.

Different ways of using boost
by Shetty, Diwakar 06 May '05

06 May '05

Hi all, I have come to the following conclusions about using boost. Do please let me know if I am wrong. 1) Download the boost src from web. 2) Build/Install the various libs using "bjam" (For intel, one can download the lib itself) 3) To use the boost lib in one's code, 3 ways are a) Just include the hdr files (e.g.: bind.hpp) The entire template impln is in hdr file b) Include the hdr files and boost will link the reqd libs automatically (e.g.: thread lib) c) Include the hdr file and specify the ".lib" file yourself. Also, whether a particular feature require 3a, 3b or 3c has to be figured out by yourself. Thanks, Diwakar

Since I use outlook for everything (or the main page's archive searching) I was not aware of this view http://lists.boost.org/boost/2005/03/date.php This speaks to what I was raising before. However it is not "in my face" (I never noticed this view existed on the site before today). I would like to amend my suggestion to be the following: 1- Formal link to the list on boost.org main page 2- Boost wiki links also a "first class citizen" link on the first page I.e. it goes from the BOTTOM of the page to the TOP- and it goes from being "Unofficial" to being one if not the FIRST thing on the list My suggestion would be to list the left pane like so: Boost Wiki Boost Mailing list (takes you to the lists view above) And then everything else Addtionally- I would add putting a link to the Wiki in the mail (previously discussed) and at the top of the "archive view" link above.

boost:bind versus bind1st
by Shetty, Diwakar 06 May '05

06 May '05

Will it be okay to say that the advantages of boost::bind over bind1st and bind2nd are 1) bind1st and bind2nd works with func obj only 2) boost::bind does not require func to have result_type and first_argument_type Thanks, Diwakar

Name of the site. As I see it, it should mention the word "Boost" so as to stand clearly among other C++-devoted sites. Something like "Got Boost" (not that I particularly love this name, but you get the idea.) I propose that we do *not* launch a contest to find the name, lest we end up spending three omnths on the issue like it happend witht he Boost logo. 2. Hosting. Dave Abrahams volunteered to host the site. Is he still holding his offer? 3. Technology. I've been doing a small survey among my workmates and some of them are ardent fans of Plone (www.plone.org) an off-the-shelf community product built on top of a content management system called Zope. I lack direct experience with Plone, but from the info I've been able to gather it supports the following features: * Site structuring using the Zope backend. * News sections. * Forums (with a component called CMF.) * Look&feel tweaking thru CSS. If you want to dig deeper, Zope provides a scripting framework using Python. * Built-in hierarchical database. * User management. * Updating workflow, meaning that everybody can contibrute entries (submitting an HTML doc or with a built-in WYSIWG editor) wiki-style, but we can make these pass thru a moderating filter. * Built-in search. * Open source, free. Preferred deployment platform is Linux, but works on Windows and Mac boxes. As I said, I don't have direct experience with Plone, so if anybody out there does maybe she can assist us on wether this is a suitable product to build the site on. I pass on less tecnhical questions like what kind of content we want to include: IMHO once we have some site prototype set up, it is easier to propose ideas and let the the thing evolve organically, so to speak.

FOREACH with only const_iterators?
by Dave Steffen 06 May '05

06 May '05

Given that this is the user list and not the development list, it might be inappropriate to ask about the FOREACH library, since it hasn't gone into an official release yet. Feel free to point me to the development list. My question is fairly simple: I have a container that only provides const_iterators; it's effectively "read-only" except to a small, select group of classes. Is there a way to tell the BOOST_FOREACH macro to use const_iterator instead of iterator? (Not a huge thing - I can add iterators to the class, or I can teach FOREACH how to iterate over it as described in the docs. I'm just wondering if I'm missing something...)

[MPL] How to Derive from inherit_linearly generated class?
by Rick Sloan 06 May '05

06 May '05

Hello all, Given a mpl::list typedef mpl::list<structA, structB, structC> typeList; and a wrapper struct template <class T> struct wrap { virtual void someFunction(T&) = 0; virtual ~wrap } You can generate a class by mpl::inherit_linearly<typeList, mpl::inherit<wrap<_2>,_1> >:;type generated; This is pretty much straight from "C++ Template Metaprogramming" pg. 193-194. My question is how do you generate the derived concrete class? I can override any particular function by struct Child : public generated { virtual void someFunction(structA&); } but I can't seem to generate an entire class. I apologize if this is a newbie question, but alas I am a newbie to template metaprogramming. Regards, Rick Sloan

sorted vectors as associative container?
by Dave Steffen 06 May '05

06 May '05

Hi Folks, Forgive me if this is a stupid question: I'm looking around for an associative-container-implemented-as-a-sorted-vector sort of thing, a la Scott Meyer's "Effective STL" item 23. I could swear Boost had such a thing, maybe called "vec_multiset" or something, a while back. Is there such a thing about? (I've looked at the 'multi-index' containers; they may be what I'm after, but they seem very complicated. My needs are _extremely_ simple...) Thanks! ---------------------------------------------------------------------- Dave Steffen, Ph.D. "The only justification for our concepts and Software Engineer IV systems of concepts is that they serve to Numerica Corporation represent the complex of our experiences; ph (970) 419-8343 x27 beyond this they have no legitimacy." fax (970) 223-6797 -- Albert Einstein dgsteffen(a)numerica.us ___________________ Numerica Disclaimer: This message and any attachments are intended only for the individual or entity to which the message is addressed.

The Boost Community
by Fernando Cacciola 05 May '05

05 May '05

Hello people, In 1998, Bemans Dawes wrote the "Proposal for a C++ Library Repository Web Site" (you can find the paper in (www.boost.org/more/index.htm) which lunched the Boost we all know and love today. The focus of the site was and is the production of high-quality peer-reviewed C++ libraries. Over the years, Boost grew as a community of experienced C++ developers with the will and means to share their expertise and work contributing to the highly respected Boost Libraries. Today, Boost is a somewhat recongisable part of the C++ programming community at large. Today, the way I see it, Boost as a community encompases only the boost developers, which are just a fraction of the larger C++ crowd. There are certainly Boost users, but I don't think we can say both developers and users form a community. I think is worth and in-the-spirit to reach out for ALL C++ programmers of ALL LEVELS around an "extended" Boost Community whose main sharing point is not just the submission of high-quality libraries but also the efficient and effective use of the language. A Boost Community site would focus not directly in the Libraries produced by Boost but on C++ itself as the great language we all love and on fostering proper use of it (which includes mixing it with other languages when appropiate). It would be volunteer-driven, just like the Boost libraries are, so the site would be moderated but open for external edition (I think a wiki would work). I envision it having home page links to the fundamental resources for C++ programmers (CUJ,ACCU, "the" books, etc), blogs from developers and users (related to state of the art C++ and/or the boost libraties), important C++ related news (not just boost-library related news), reviews, etc... essentially, everything the will of volunteers can bring on to the community. The motto being "fostering proper use of C++". A minimum of moderation would be required but I assume not much. I know there are other programmer communities around (even C++ focused). The reason I propose this here (around Boost) is becasue I think that a community centered around the Boost Libraries but reaching out could stand out for its quality in the same way the Boost Libraries do. I also know that a newsgroup or mailing list is a form of community, and we have c.l.cpp.m and c.s.cpp. But they lack the verstile structure and dynamism of the today's virtual communities. Also, somehow I believe that centering a community around the Boost Libraries would spread their quality into the rest of the site; to some degree at least. I welcome comments, ctricticism and I call interested people to put forward concrete ideas. Best Fernando Cacciola SciSoft
