Time series: sparse/dense containers for use with non-time-indexed data?
by Phil Endecott 09 Aug '07

09 Aug '07

I have had a look at the Time Series docs and it looks like a worthwhile library, though I have not done anything recently with time-indexed data that could use it. I have, however, had to deal with sparse vs. dense data structure decisions with other index types, e.g. integers; this leads me to wonder what ties this library specifically to _time_ series. One of the elements of this library is a pair of containers that have a common interface but store their contents either in a dense or a sparse structure. I wonder whether it would be worth generalising those containers to make them applicable to non-time applications - and to make them as close to standard library containers as possible. One way to approach this would be to think about how a std::map-like interface can be presented to a std::vector, and/or how a std::vector-like interface can be presented to a std::map. My motivation is that I sometimes find myself with code like this: typedef std::map<int,T> T_container; // I'm not sure yet if this is best stored in a sparse T_container tt; // (map) or dense (vector) structure, but by making // it a typedef I can easily change it later. Of course, when I change the typedef from map<int,T> to vector<T> I discover that there are plenty of other places where I have to change the code; for example I have to add or remove '->second' wherever I dereference an iterator. How about: dense_map<int,T> : provides the interface of std::map<int,T> (or a subset of it), implemented using a vector. Needs to grow the vector when something is inserted. sparse_vector<T> : provides the interface of std::vector<T> (or a subset of it), implemented using a map. Needs an iterator that can point to gaps between the map elements. How close do the sparse and dense time series containers come to this? Regards, Phil.

[Subversion] Library authors, please read

There was some mild corruption in the Sourceforce CVS repository that made it unclear whether some files actually belonged in the Subversion trunk or not. The following list of files were in this kind of limbo; please glance through the list of differences between boost-svn (Subversion) and boost-cvs (CVS), and make any of the necessary corrections in the Subversion repository for your libraries.

[MD5] now in the vault
by Kevin Sopp 08 Aug '07

08 Aug '07

Hi all, I finished my own MD5 implementation today and decided to boostify it. It's not header only which is slightly inconvenient but Jamfiles, Docs and Tests are provided. Comments on the interface and other things are welcome! http://boost-consulting.com/vault/index.php?action=downloadfile&filename=md… just extract it to your boost directory and run 'bjam md5' regards, Kevin Sopp

Entry for Océ on Who's using Boost
by Peters, Richard 08 Aug '07

08 Aug '07

Hello all, The company I'm working for is using Boost for a year now, and we're very happy that we started using it. I would like to submit an entry to the Who's using Boost page, for the "In House Boost" section: -------------------------------- Océ-Technologies B.V. Throughout the world Océ is one of the major suppliers of document management and printing systems and the related services. We develop, manufacture, service and sell printers, scanners, peripheral equipment and media, supported by unique software. Océ products for the corporate and commercial market are widely known for their quality, ease of use, speed and reliability. "The Boost libraries enable us to get a higher degree of uniformity and quality in our code. During a redesign last year we found that lots of small constructions from Boost shortens development time and prevents having to reinvent many wheels. Libraries that we use include assign, date_time, enable_if, filesystem, format, function, iterators, multi_index, operators, optional, pointer_container, signals, smart_ptr, thread, and variant." --------------------------------- URL to our website: http://www.oce.com Best regards, Richard Peters This message and attachment(s) are intended solely for use by the addressee and may contain information that is privileged, confidential or otherwise exempt from disclosure under applicable law.

Time Series "review"
by Lewis Hyatt 08 Aug '07

08 Aug '07

Hi, here are my quick thoughts on this library. I don't have time for much more than this... sorry it isn't more thorough. * What is your evaluation of the design? I guess my first impression was "way too many concepts", but after a while it all starts to make sense. It seems pretty flexible what you can do with it. It looks quite daunting at first to write new series classes, but that probably isn't going to be that common a task. Writing new algorithms seems pretty straightforward and I wouldn't mind trying to add some new ones. * What is your evaluation of the potential usefulness of the library? I don't have a current use for it, but I can see how a lot of people would! * Did you try to use the library? With what compiler? Did you have any problems? cygwin only has boost 1.33 still, and I didn't have time to get 1.34.1, so I was missing too much stuff to compile the library. * How much effort did you put into your evaluation? A glance? A quick reading? In-depth study? About an hour reading the docs and looking at the examples. * Are you knowledgeable about the problem domain? More or less. I do a lot of data analyis with std::vector and legacy C libraries like clapack. Here are some random comments: -I don't like the names "daily", "weekly", etc, because they give the impression that the library is only meant for daily data. I think it would be better just to define a template stride<> inheriting from mpl::int_<>, so you could write instead something like dense_series<double, stride<7> > and the meaning of 7 would depend on the context of the program. -I am confused by the statement in the docs that "A time series is a series of data points, sampled at regular intervals". If that's true, then what does it mean to use a floating point offset? Doesn't that mean I can use irregular intervals too? I was thinking it would be natural to have an FFT algorithm for a dense time series, but that would only make sense if it was sampled at regular intervals. I guess a dense series always has an integral offset type, so it would make sense there. -I worry a little about the dual interfaces for ordered_inserter, maybe it should be split into two classes? Especially for the output iterator usage, I think people would frequently try to use it with std::copy and then forget to call commit(), causing silent errors. Maybe that's just something the user will have to get used to. Another option could be to use a new class called ordered_insert_iterator with a shared_ptr pImpl setup, so that the last temporary object would call commit() from its destructor after the algorithm completed. In that case, problems would be caused if people created non-temporary objects, but I think in practice, in the majority of cases, the output iterator would be used by creating a temporary object and passing it to std::copy or whatever. -I think invert_elements() should have a different name. For one thing, there is confusion with invert_heaviside(), which is completely unrelated, and for another, this name could also work fine to describe a function which multiplied every element by -1. I can't think of a decent one, though. * Do you think the library should be accepted as a Boost library? Given that I didn't have time to look into this much more, I'm not sure how seriously my opinion can be taken, but I do vote yes. -Lewis

[Boost][Interprocess] Lengthy test runtimes
by K. Noel Belcourt 08 Aug '07

08 Aug '07

Hi, The named_recursive test in boost.interprocess takes an excessive amount of time to run. Here you can see it's been running for 45+ minutes 13008 kbelco 25 0 14988 1360 1176 R 99.9 0.0 46:28.97 named_recursive 13014 kbelco 25 0 15040 1380 1188 R 99.8 0.0 46:10.09 named_recursive on fast hardware processor : 3 vendor_id : GenuineIntel cpu family : 6 model : 15 model name : Intel(R) Xeon(R) CPU 5160 @ 3.00GHz Is there something wrong with this test, or my system? I'd like to request that this test be removed or somehow scaled back so it runs a bit faster. Is this possible? Thanks. -- Noel Belcourt

[www] typo in ptr_container online docs (but not in CVS)

07 Aug '07

Hi all, when I look at http://boost.org/libs/ptr_container/doc/ptr_container.html I see a link to "The Clobable Concept" but the version in CVS says Clonable. Can someone with access to the webserver fix the 'b' ? Jon

Howdy, The web page on compiler status: http://boost.org/status/compiler_status.html still has an acknowledgement for KAI Software, which IIUC no longer exists. Should that go away? ron
