  • python regex of a date in some text, enclosed by two keywords

    - by Horace Ho
    This is Part 2 of this question and thanks very much for David's answer. What if I need to extract dates which are bounded by two keywords? Example: text = "One 09 Jun 2011 Two 10 Dec 2012 Three 15 Jan 2015 End" Case 1 bounding keyboards: "One" and "Three" Result expected: ['09 Jun 2011', '10 Dec 2012'] Case 2 bounding keyboards: "Two" and "End" Result expected: ['10 Dec 2012', '15 Jan 2015'] Thanks!

  • In CodeIgniter, how to clear "form data" after redirecting page

    - by Obay
    I'm not sure I explained it correctly in the question title, so here's the details: Login controller: function authenticate() { if ( authorized ) { redirect('lobby'); } else { redirect('login'); } } Lobby controller: function index() { //load lobby view } What happens is that in the login page, I enter user / pass, click Login, then authenticate() is called, and redirects me to the Lobby. However, when I click refresh while on the Lobby, the login form gets submitted again, so I get "logged in" again. How do I prevent that from happening?

  • Recommendations for a free GIS library supporting raster images

    - by gspr
    Hi. I'm quite new to the whole field of GIS, and I'm about to make a small program that essentially overlays GPS tracks on a map together with some other annotations. I primarily need to allow scanned (thus raster) maps (although it would be nice to support proper map formats and something like OpenStreetmap in the long run). My first exploratory program uses Qt's graphics view framework and overlays the GPS points by simply projecting them onto the tangent plane to the WGS84 ellipsoid at a calibration point. This gives half-decent accuracy, and actually looks good. But then I started wondering. To get the accuracy I need (i.e. remove the "half" in "half-decent"), I have to correct for the map projection. While the math is not a problem in itself, supporting many map projection feels like needless work. Even though a few projections would probably be enough, I started thinking about just using something like the PROJ.4 library to do my projections. But then, why not take it all the way? Perhaps I might aswell use a full-blown map library such as Mapnik (edit: Quantum GIS also looks very nice), which will probably pay off when I start to want even more fancy annotations or some other symptom of featuritis. So, finally, to the question: What would you do? Would you use a full-blown map library? If so, which one? Again, it's important that it supports using (and zooming in and out with) raster maps and has pretty overlay features. Or would you just keep it simple, and go with Qt's own graphics view framework together with something like PROJ.4 to handle the map projections? I appreciate any feedback! Some technicalities: I'm writing in C++ with a Qt-based GUI, so I'd prefer something that plays relatively nicely with those. Also, the library must be free software (as in FOSS), and at least decently cross-platform (GNU/Linux, Windows and Mac, at least). Edit: OK, it seems I didn't do quite enough research before asking this question. Both Quantum GIS and Mapnik seem very well suited for my purpose. The former especially so since it's based on Qt.

  • OPS4j repository alternative

    - by Paul Whelan
    The OPS4J repository is down at present and I am trying to run pax-provision using a profile for spring-dm. My question is how do I tell maven to locate the profile information from a site other than ops4j.org. Is this possible? ideally I would like to cache all the packages from the repo especially the spring-dm details which seem never to be cached and are downloaded all the time making coding on the train and times when the site is down impossible. Thanks Paul

  • How many copies of files are needed by video server?

    - by Trilok
    A quick question. How many copies of the same movie are kept in a video server (a video streaming server)? Suppose a particular video is at max requested by 1000 users at the same instant of time, how many copies would be sufficient so that parallel streams can be provided to each user? Ideally 1 copy would solve the purpose, but what is the optimum number keeping the bandwidth and simultaneous access in mind?

  • Filtering Attributes with Weka

    - by hrzafer
    Hi eveyone! I have a simple question about filtering attributes in WEKA. Let's say I have 500 attributes 30 classes and 100 samples for each class which equals 3000 rows and 500 columns. This causes time and memory problems a you can guess. How do I filter attributes that occur only once or twice (or n times) in 3000 rows. And is it a good idea? Thank you

  • Facebook connect on Google App Engine with Django Patch

    - by yoav.aviram
    We are building a website on Google App Engine, using django patch. We would like to use Facebook connect for two purposes: Authenticate users. Access user's social data. Searching for a solution in the usual places (google, FB, SO) brigs up a lot of noise, many partial solutions and no clear answer. So the question is this: does anyone has a clear working solution? maybe even a recipe? Thanks.

  • Changing directory in Open File Dialog programatically.

    - by ofarooq
    Hi All, I have a customized OpenFileDialog (VS2008, C#, Windows Forms) with a ComboBox. The ComboBox will have a list of paths which the user can select. My question, is there a way I can change the directory in Open File Dialog to point to the path in the combobox selected item. InitialDirectory works only before I open the dialog, I wanted a way to change the directory programatically after the dialog is open. Thanks

  • Access to Perl's empty angle "<>" operator from an actual filehandle?

    - by Ryan Thompson
    I like to use the nifty perl feature where reading from the empty angle operator <> magically gives your program UNIX filter semantics, but I'd like to be able to access this feature through an actual filehandle (or IO::Handle object, or similar), so that I can do things like pass it into subroutines and such. Is there any way to do this? This question is particularly hard to google, because searching for "angle operator" and "filehandle" just tells me how to read from filehandles using the angle operator.

  • MOSS 2007 - list permission

    - by nav
    Hi All, I have configured my list so that users can only read and edit items they have created. I now need to configure this list so that a particular group of users can edit and read all items on this list. I know users with the 'Manage Lists' permission would be able to do this. My question is can this be configured to be even more granular to apply a permission that works like the 'Manage Lists' permission but only for a particular list, rather than all lists? Many Thanks, Nav

  • Sibling UIViewController Navigation

    - by Joo Park
    would anybody care to comment on this piece of code? It allows you to do "prev" or "next" once in the detail view of a uiviewcontroller. So, if you have 4 uiviewcontrollers, you can navigate from #3 to #2 with previous or #3 to #4 with next. It works, but, my question is, is this the best way to implement this? or, is there a better way. http://github.com/joop23/UIViewController
